Description
PSIVIA ANTIBODIES AND PROTEIN MULTIMERS
Field of the Invention This invention relates generally to the field of cancer associated polypeptides and antibodies that recognize native epitopes on the polypeptides. In particular, the invention relates in part to antibodies or antigen-binding fragments thereof which bind specifically to conformational epitopes on the extracellular domain of PSMA, rnultimeric forms of PSMA
proteins, antibodies that selectively bind to the m.ultimers, and compositions containing such antibodies or multimers.
Background of the Invention Prostate cancer is the most prevalent type of cancer and the second leading cause of death from cancer in American men, with an estimated 179,000 cases and 37,000 deaths in 1999, (Landis, S.H. et al. CA Cancer J. Clin. 48:6-29 (1998)). The number of men diagnosed with prostate cancer is steadily increasing as a result of the increasing population of older men as well as a greater awareness of the disease leading to its earlier diagnosis (Parker et al., 1997, CA Cancer .1. Clin. 47:5-280). The life time risk for men developing prostate cancer is about 1 in 5 for Caucasians, 1 in 6 for African Americans. High risk groups are represented by those with a positive family history of prostate cancer or African Americans.
Over a lifetime, more than 2/3 of the men diagnosed with prostate cancer die of the disease (Wingo et al., 1996, CA Cancer J. Clin. 46:113-25). Moreover, many patients who do not succumb to prostate cancer require continuous treatment to ameliorate symptoms such as pain, bleeding and urinary obstruction. Thus, prostate cancer also represents a major cause of suffering and increased health care expenditures.
Where prostate cancer is localized and the patient's life expectancy is 10 years or more, radical prostatectomy offers the best chance for eradication of the disease.

Where prostate cancer is localized and the patient's life expectancy is 10 years or more, radical prostatectomy offers the best chance for eradication of the disease.
- 2 -Historically, the drawback of this procedure is that most cancers had spread beyond the bounds of the operation by the time they were detected. Patients with bulky, high-grade tumors are less likely to be successfully treated by radical prostatectomy.
Radiation therapy has also been widely used as an alternative to radical prostatectomy. Patients generally treated by radiation therapy are those who are older and less healthy and those with higher-grade, more clinically advanced tumors.
Particularly preferred procedures are external-beam therapy which involves three dimensional, confocal radiation therapy where the field of radiation is designed to conform to the volume of tissue treated;
interstitial-radiation therapy where seeds of radioactive compounds are implanted using ultrasound guidance; and a combination of external-beam therapy and interstitial-radiation therapy.
For treatment of patients with locally advanced disease, hormonal therapy before or following radical prostatectomy or radiation therapy has been utilized.
Hormonal therapy is the main form of treating men with disseminated prostate cancer. Orchiectomy reduces serum testosterone concentrations, while estrogen treatment is similarly beneficial.
Diethylstilbestrol from estrogen is another useful hormonal therapy which has a disadvantage of causing cardiovascular toxicity. When gonadotropin-releasing hormone agonists are administered testosterone concentrations are ultimately reduced. Flutamide and other nonsteroidal, anti-androgen agents block binding of testosterone to its intracellular receptors.
As a result, it blocks the effect of testosterone, increasing serum testosterone concentrations and allows patients to remain potent--a significant problem after radical prostatectomy and radiation treatments.
Cytotoxic chemotherapy is largely ineffective in treating prostate cancer. Its toxicity makes such therapy unsuitable for elderly patients. In addition, prostate cancer is relatively resistant to cytotoxic agents.
Relapsed or more advanced disease is also treated with anti-androgen therapy.
Unfortunately, almost all tumors become hormone-resistant and progress rapidly in the absence of any effective therapy.
Accordingly, there is a need for effective therapeutics for prostate cancer which are not overwhelmingly toxic to normal tissues of a patient, and which are effective in selectively eliminating prostate cancer cells.

- 21 -Detailed Description of the Invention The present invention provides antibodies or antigen-binding fragments thereof which bind specifically to conformational epitopes on the extracellular domain of PSMA, compositions containing one or a combination of such antibodies or antigen-binding fragments thereof, hybridoma cell lines that produce the antibodies, and methods of using the antibodies or antigen-binding fragments thereof for cancer diagnosis and treatment.
Prostate specific membrane antigen (PSMA) is a 100 kD Type II membrane glycoprotein expressed in prostate tissues and was originally identified by reactivity with a monoclonal antibody designated 7E11-05 (Horoszewicz et al., 1987, Anticancer Res. 7:927-935; U.S. Pat. No. 5,162,504). PSMA was obtained in purified form (Wright et al., 1990, Antibody Immunoconjugates and Radio Pharmaceuticals 3:Abstract 193) and characterized as a type II transmembrane protein having sequence identity with the transferrin receptor (Israeli et al., 1994, Cancer Res. 54:1807-1811) and with NAALADase activity (Carter et al., 1996, Proc. Natl. Acad. Sci. U.S.A. 93:749-753). More importantly, PSMA is expressed in increased amounts in prostate cancer, and elevated levels of PSMA are also detectable in the sera of these patients (Horoszewicz et al., 1987; Rochon et al., 1994, Prostate 25:219-223;
Murphy et al., 1995, Prostate 26:164-168; and Murphy et al., 1995, Anticancer Res. 15:1473-1479). PSMA expression increases with disease progression, becoming highest in metastatic, hormone-refractory disease for which there is no present therapy. Provocative recent data indicates that PSMA is also abundantly expressed on the neovasculature of a variety of other important tumors, including bladder, pancreas, sarcoma, melanoma, lung, and kidney tumor cells, but not on normal vasculature.
One aspect of the invention provides an isolated antibody or an antigen-binding fragment thereof which specifically binds to an extracellular domain of PSMA
wherein the antibody or the antigen-binding fragment thereof competitively inhibits the specific binding of a second antibody to its target epitope on PSMA, and wherein the second antibody is selected from the group consisting of PSMA 3.7, PSMA 3.8, PSMA 3.9, PSMA 3.11, PSMA

The term "high stringency conditions" as used herein refers to parameters with which the art is familiar. Nucleic acid hybridization parameters may be found in references that compile such methods, e.g. Molecular Cloning: A Laboratory Manual, J.
Sambrook, et al., eds., Second Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York, 1989, or Current Protocols in Molecular Biology, F.M. Ausubel, et al., eds., John Wiley &
Sons, Inc., New York. One example of high-stringency conditions is hybridization at 65 C in TM
hybridization buffer (3.5X SSC, 0.02% Ficoll, 0.02% polyvinyl pyrrolidone, 0.02% Bovine Serum Albumin, 2.5mM NaH2PO4(pH7), 0.5% SDS, 2mM EDTA). SSC is 0.15M sodium chloride/0.015M sodium citrate, p117; SDS is sodium dodecyl sulphate; and EDTA
is ethylenediaminetetracetic acid. After hybridi7ation, a membrane upon which the nucleic acid is transferred is washed, for example, in 2X SSC at room temperature and then at 0.1 - 0.5X

Antigen-binding fragments of the foregoing also are provided, as described elsewhere herein.
As used herein, the term "antibody" refers to a glycoprotein comprising at least two heavy (H) chains and two light (L) chains inter-connected by disulfide bonds.

The
- 28 -variable regions of the heavy and light chains contain a binding domain that interacts with an antigen. The constant regions of the antibodies may mediate the binding of the immunoglobulin to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (Cl q) of the classical complement system.
The term "antigen-binding fragment" of an antibody as used herein, refers to one or more portions of an antibody that retain the ability to specifically bind to an antigen (e.g., PSMA). It has been shown that the antigen-binding function of an antibody can be performed by fragments of a full-length antibody. Examples of binding fragments encompassed within the term "antigen-binding fragment" of an antibody include (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab')2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL
and VH domains of a single arm of an antibody, (v) a dAb fragment (Ward et al., (1989) Nature 341:544-546) which consists of a VH domain; and (vi) an isolated complementarity determining region (CDR). Furthermore, although the two domains of the Fv fragment, V
and VH, are coded for by separate genes, they can be joined, using recombinant methods, by a synthetic linker that enables them to be made as a single protein chain in which the VL and VH regions pair to form monovalent molecules (known as single chain Fv (scFv);
see e.g., Bird et al. (1988) Science 242:423-426; and Huston et al. (1988) Proc. Natl.
Acad. Sci. USA
85:5879-5883). Such single chain antibodies are also intended to be encompassed within the term "antigen-binding portion" of an antibody. These antibody fragments are obtained using conventional procedures, such as proteolytic fragmentation procedures, as described in J.
Goding, Monoclonal Antibodies: Principles and Practice, pp 98-118 (N.Y.
Academic Press 1983). The fragments are screened for utility in the same manner as are intact antibodies.
An "isolated antibody", as used herein, is intended to refer to an antibody which is substantially free of other antibodies having different antigenic specificities (e.g., an isolated antibody that specifically binds to PSMA is substantially free of antibodies that specifically bind antigens other than PSMA). An isolated antibody that specifically binds to an epitope, isoform or variant of PSMA may, however, have cross-reactivity to other related antigens, e.g., from other species (e.g., PSMA species homologs).

An isolated antibody that specifically binds to an epitope, isoform or variant of PSMA may, however, have cross-reactivity to other related antigens, e.g., from other species (e.g., PSMA species homologs). Moreover, an isolated antibody may
- 29 -be substantially free of other cellular material and/or chemicals. As used herein, "specific binding" refers to antibody binding to a predetermined antigen. Typically, the antibody binds with an affinity that is at least two-fold greater than its affinity for binding to a non-specific antigen (e.g., BSA, casein) other than the predetermined antigen or a closely-related antigen.
The isolated antibodies of the invention encompass various antibody isotypes, such as IgGl, IgG2, IgG3, IgG4, IgM, IgAl, IgA2, IgAsec, IgD, IgE. As used herein, "isotype"

The antibodies can be full length or can include only an antigen-binding fragment such as the antibody constant and/or variable domain of IgGl, IgG2, IgG3, IgG4, IgM, IgAl, IgA2, IgAsec, IgD or IgE or could consist of a Fab fragment, a F(ab1)2 fragment, and a Fv fragment.
The antibodies of the present invention can be polyclonal, monoclonal, or a mixture of polyclonal and monoclonal antibodies. The antibodies can be produced by a variety of techniques well known in the art. Procedures for raising polyclonal antibodies are well known. For example anti-PSMA polyclonal antibodies are raised by administering PSMA.
protein subcutaneously to New Zealand white rabbits which have first been bled to obtain pre-immune serum. The PSMA can be injected at a total volume of 100 tl per site at six different sites, typically with one or more adjustments. The rabbits are thembled two weeks after the first injection and periodically boosted with the same antigen three times every six weeks. A sample of serum is collected 10 days after each boost. Polyclonal antibodies are recovered from the serum, preferably by affinity chromatography using PSMA to capture the antibody. This and other procedures for raising polyclonal antibodies are disclosed in E.
Harlow, et. al., editors, Antibodies: A Laboratory Manual (1988).
Monoclonal antibody production may be effected by techniques which are also well known in the art. The term "monoclonal antibody," as used herein, refers to a preparation of antibody molecules of single molecular composition. A monoclonal antibody displays a single binding specificity and affinity for a particular epitope. The process of monoclonal antibody production involves obtaining immune somatic cells with the potential for producing antibody, in particular B lymphocytes, which have been previously immunized with the antigen of interest either in vivo or in vitro and that are suitable for fusion with a B-cell myeloma line.
The isolated antibodies of the invention encompass various antibody isotypes, such as IgGl, IgG2, IgG3, IgG4, IgM, IgAl, IgA2, IgAsec, IgD, IgE. As used herein, "isotype"
refers to the antibody class (e.g. IgM or IgG1) that is encoded by heavy chain constant region genes. The antibodies can be full length or can include only an antigen-binding fragment such as the antibody constant and/or variable domain of IgGl, IgG2, IgG3, IgG4, IgM, IgAl, IgA2, IgAsec, IgD or IgE or could consist of a Fab fragment, a F(ab1)2 fragment, and a Fv fragment.

- 30 -Mammalian lymphocytes typically are immunized by in vivo immunization of the animal (e.g., a mouse) with the desired protein or polypeptide, e.g., with PSMA in the present invention. Such immunizations are repeated as necessary at intervals of up to several weeks to obtain a sufficient titer of antibodies. Once immunized, animals can be used as a source of antibody-producing lymphocytes. Following the last antigen boost, the animals are sacrificed and spleen cells removed. Mouse lymphocytes give a higher percentage of stable fusions with the mouse myeloma lines described herein. Of these, the BALB/c mouse is preferred.
However, other mouse strains, rabbit, hamster, sheep and frog may also be used as hosts for preparing antibody-producing cells. See; Goding (in Monoclonal Antibodies:
Principles and Practice, 2d ed., pp. 60-61, Orlando, Fla., Academic Press, 1986). In particular, mouse strains that have human imm-unoglobulin genes inserted in the genome (and which cannot produce mouse immunoglobulins) are preferred. Examples include the HuMAb mouse strains produced by Medarex/GenPharm International, and the XenoMouse strains produced by Abgenix. Such mice produce fully human iinmunoglobulin molecules in response to immunization.
Those antibody-producing cells that are in the dividing plasmablast stage fuse preferentially. Somatic cells may be obtained from the lymph nodes, spleens and peripheral blood of antigen-primed animals, and the lymphatic cells of choice depend to a large extent on their empirical usefulness in the particular fusion system. The antibody-secreting lymphocytes are then fused with (mouse) B cell myeloma cells or transformed cells, which are capable of replicating indefinitely in cell culture, thereby producing an immortal, immunoglobulin-secreting cell line. The resulting fused cells, or hybridomas, are cultured, and the resulting colonies screened for the production of the desired monoclonal antibodies.
Colonies producing such antibodies are cloned, and grown either in vivo or in vitro to produce large quantities of antibody. A description of the theoretical basis and practical methodology of fusing such cells is set forth in Kohler and Milstein, Nature 256:495 (1975).
Alternatively, human somatic cells capable of producing antibody, specifically B
lymphocytes, are suitable for fusion with myeloma cell lines. While B
lymphocytes from biopsied spleens, tonsils or lymph nodes of an individual may be used, the more easily accessible peripheral blood B lymphocytes are preferred. The lymphocytes may be derived from patients with diagnosed prostate carcinomas or another PSMA-expressing cancer. In

Although somatic cell hybridization procedures are preferred, in principle, other techniques for producing monoclonal antibodies can be employed such as viral or oncogenic transformation of B lymphocytes.
Myeloma cell lines suited for use in hybridoma-producing fusion procedures preferably are non-antibody-producing, have high fusion efficiency, and enzyme deficiencies that render them incapable of growing in certain selective media which support the growth of the desired hybridomas. Examples of such myeloma cell lines that may be used for the production of fused cell lines include P3-X63/Ag8, X63-Ag8.653, NS1/1.Ag 4.1, Sp2/0-Ag14, FO, NSO/U, MPC-11, MPC11-X45-GTG 1.7, S194/5XXO Bul, all derived from mice;

Fusion with mammalian myeloma cells or other fusion partners capable of replicating indefinitely in cell culture is effected by standard and well-known techniques, for example, by using polyethylene glycol ("PEG") or other fusing agents (See Milstein and Kohler, Eur.

The term "recombinant antibody", as used herein, is intended to include antibodies that are prepared, expressed, created or isolated by recombinant means, such as antibodies isolated from an animal (e.g., a mouse) that is transgenic for another species' immunoglobulin genes, antibodies expressed using a recombinant expression vector transfected into a host cell, antibodies isolated from a recombinant, combinatorial antibody library, or antibodies prepared, expressed, created or isolated by any other means that involves splicing of immunoglobulin gene sequences to other DNA sequences.

As used herein, the term "chimeric antibody" refers to an antibody, that combines the murine variable or hypervariable regions with the human constant region or constant and variable
- 32 -framework regions. As used herein, the term "humanized antibody" refers to an antibody that retains only the antigen-binding CDRs from the parent antibody in association with human framework regions (see, Waldmann, 1991, Science 252:1657). Such chimeric or humanized antibodies retaining binding specificity of the murine antibody are expected to have reduced immunogenicity when administered in vivo for diagnostic, prophylactic or therapeutic applications according to the invention.
According to an alternative embodiment, the monoclonal antibodies of the present invention can be modified to be in the form of a bispecific antibody, or a multispecific antibody. The term "bispecific antibody" is intended to include any agent, e.g., a protein, peptide, or protein or peptide complex, which has two different binding specificities which bind to, or interact with (a) a cell surface antigen and (b) an Fc receptor on the surface of an effector cell. The term "multispecific antibody" is intended to include any agent, e.g., a protein, peptide, or protein or peptide complex, which has more than two different binding specificities which bind to, or interact with (a) a cell surface antigen, (b) an Fc receptor on the surface of an effector cell, and (c) at least one other component.
Accordingly, the invention includes, but is not limited to, bispecific, trispecifie, tetraspecific, and other multispecific antibodies which are directed to cell surface antigens, such as PSMA, and to Fc receptors on effector cells. The term "bispecific antibodies" further includes diabodies.
Diabodies are bivalent, bispecific antibodies in which the VH and VL domains are expressed on a single polyp eptide chain, but using a linker that is too short to allow for pairing between the two domains on the same chain, thereby forcing the domains to pair with complementary domains of another chain and creating two antigen-binding sites (see e.g., Holliger, P., et al. (1993) Proc. Natl. Acad. Sci. USA 90:6444-6448; Poijak, R.J., et al. (1994) Structure 2:1121-1123).
A bispecific antibody can be formed of an antigen-binding region specific for the extracellular domain of PSMA and an antigen-binding region specific for an effector cell which has tumoricidal or tumor inhibitory activity. The two antigen-binding regions of the bispecific antibody are either chemically linked or can be expressed by a cell genetically engineered to produce the bispecific antibody. (See generally, Fanger et al., 1995 Drug News & Perspec. 8(3):133-137). Suitable effector cells having tumoricidal activity include but are not limited to cytotoxic T-cells (primarily CD8+ cells), natural killer cells, etc. An effective amount of a bispecific antibody according to the invention is administered to a prostrate

- 33 -cancer patient and the bispecific antibody kills and/or inhibits proliferation of the malignant cells after localization at sites of primary or metastatic tumors bearing PSMA.
In certain embodiments, the antibodies are human antibodies. The term "human antibody", as used herein, is intended to include antibodies having variable and constant regions derived from human germline immunoglobulin sequences. The human antibodies of the invention may include amino acid residues not encoded by human germline immunoglobulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo). However, the term "human antibody", as used herein, is not intended to include antibodies in which CDR sequences derived from the germline of another mammalian species, such as a mouse have been grafted onto human framework sequences (referred to herein as "humanized antibodies"). Human antibodies directed against PSMA are generated using transgenic mice carrying parts of the human immune system rather than the mouse system.
Fully human monoclonal antibodies also can be prepared by immunizing mice transgenic for large portions of human immunoglobulin heavy and light chain loci. See, e.g., U.S. patents 5,591,669, 5,598,369, 5,545,806, 5,545,807, 6,150,584, and references cited therein. These animals have been genetically modified such that there is a functional deletion in the production of endogenous (e.g., murine) antibodies. The animals are further modified to contain all or a portion of the human germ-line immunoglobulin gene locus such that immunization of these animals results in the production of fully human antibodies to the antigen of interest.
Following immunization of these mice (e.g., XenoMouse (Abgenix), HuMAb mice (Medarex/GenPharm)), monoclonal antibodies are prepared according to standard hybridoma technology. These monoclonal antibodies have human immunoglobulin amino acid sequences and therefore will not provoke human anti-mouse antibody (HAMA) responses when administered to humans.
Preferably, the mice are 6-16 weeks of age upon the first immunization. For example, a purified or enriched preparation of PSMA antigen (e.g., recombinant PSMA or PSMA-expressing cells) is used to immunize the mice intraperitoneally (IP), although other routes of immunization known to one of ordinary skill in the art are also possible. PSMA
antigen is injected in combination with an adjuvant, such as complete Freund's adjuvant, and preferably the initial injection is followed by booster immunizations with antigen in an adjuvant, such as

- 34 -incomplete Freund's adjuvant. The immune response is monitored over the course of the immunization protocol with plasma samples obtained by, for example, retroorbital bleeds.
The plasma is screened by ELISA (as described below), and mice with sufficient titers of anti-PSMA human immunoglobulin are used for fusions. Mice are boosted intravenously with antigen 3 days before sacrifice and removal of the spleen.

Plasmids of the invention include plasmids selected from the group consisting of: AB-PG1-XG1-006 Heavy Chain (SEQ ID NO: 2), AB-PG1-XG1-006 Light Chain (SEQ ID NO: 8), AB-PG1-XG1-026 Heavy Chain (SEQ ID NO: 3), AB-PG1-XG1-026 Light Chain (SEQ ID NO: 9), AB-PG1-XG1-051 Heavy Chain (SEQ JD NO: 4), AB-PG1-XG1-051 Light Chain (SEQ ID NO: 10), AB-PG1-XG1-069 Heavy Chain (SEQ ID

The isolated antibody or antigen-binding fragment thereof preferably is selected for its ability to bind live cells expressing PSMA. In order to *demonstrate binding of monoclonal antibodies to live cells expressing the PSMA, flow cytometry can be used. For example, cell lines expressing PSMA (grown under standard growth conditions) or prostate cancer cells that express PSMA are mixed with various concentrations of monoclonal antibodies in PBS
TM
containing 0.1% Tween 80 and 20% mouse serum, and incubated at 37 C for 1 hour. After washing, the cells are reacted with fluorescein-labeled anti-human IgG
secondary antibody (if human anti-PSMA antibodies were used) under the same conditions as the primary antibody staining._ The samples can be analyzed by a fluorescence activated cell sorter (FACS) instrument using light and side scatter properties to gate on single cells. An alternative assay using fluorescence microscopy may be used (in addition to or instead of) the flow cytometry assay. Cells can be stained exactly as described above and examined by fluorescence microscopy. This method allows visualization of individual cells, but may have diminished sensitivity depending on the density of the antigen.
Binding of the antibody or antigen-binding fragment thereof to live cells expressing PSMA can inhibit the growth of the cells or mediate cytolysis of the cells.
Cytolysis can be complement mediated or can be mediated by effector cells. In a preferred embodiment, the cytolysis is carried out in a living organism, preferably a mammal, and the live cell is a tumor cell. In a preferred embodiment the tumor cell is a prostate cancer cell.

In order to *demonstrate binding of monoclonal antibodies to live cells expressing the PSMA, flow cytometry can be used. For example, cell lines expressing PSMA (grown under standard growth conditions) or prostate cancer cells that express PSMA are mixed with various concentrations of monoclonal antibodies in PBS
TM
containing 0.1% Tween 80 and 20% mouse serum, and incubated at 37 C for 1 hour. After washing, the cells are reacted with fluorescein-labeled anti-human IgG
secondary antibody (if human anti-PSMA antibodies were used) under the same conditions as the primary antibody staining._ The samples can be analyzed by a fluorescence activated cell sorter (FACS) instrument using light and side scatter properties to gate on single cells. An alternative assay using fluorescence microscopy may be used (in addition to or instead of) the flow cytometry assay. Cells can be stained exactly as described above and examined by fluorescence microscopy. This method allows visualization of individual cells, but may have diminished sensitivity depending on the density of the antigen.
Binding of the antibody or antigen-binding fragment thereof to live cells expressing PSMA can inhibit the growth of the cells or mediate cytolysis of the cells.
Cytolysis can be complement mediated or can be mediated by effector cells. In a preferred embodiment, the cytolysis is carried out in a living organism, preferably a mammal, and the live cell is a tumor cell. In a preferred embodiment the tumor cell is a prostate cancer cell.
- 36 -The testing of antibody cytolytic activity in vitro by chromium release assay can provide an initial screening prior to testing in vivo models. This testing can be carried out using standard chromium release assays. Briefly, polymorphonuclear cells (PMN), or other effector cells, from healthy donors can be purified by Ficoll Hypaque density centrifugation, followed by lysis of contaminating erythrocytes. Washed PMNs can be suspended in RPMI
supplemented with 10% heat-inactivated fetal calf serum and mixed with 51Cr labeled cells expressing PSMA, at various ratios of effector cells to tumor cells (effector cells:tumor cells).
Purified anti-PSMA IgGs can then be added at various concentrations.
Irrelevant IgG can be used as negative control. Assays can be carried out for 0-120 minutes at 37 C.
Samples can be assayed for cytolysis by measuring 51Cr release into the culture supernatant. Anti-PSMA
monoclonal antibodies can also be tested in combinations with each other to determine whether cytolysis is enhanced with multiple monoclonal antibodies.
Antibodies which bind to PSMA also can be tested in an in vivo model (e.g., in mice) to determine their efficacy in mediating cytolysis and killing of cells expressing PSMA, e.g., tumor cells. These antibodies can be selected, for example, based on the following criteria, which are not intended to be exclusive:
1) binding to live cells expressing PSMA;
2) high affinity of binding to PSMA;
3) binding to a unique epitope on PSMA (to eliminate the possibility that antibodies with complimentary activities when used in combination would compete for binding to the same epitope);
4) opsonization of cells expressing PSMA;
5) mediation of growth inhibition, phagocytosis and/or killing of cells expressing PSMA in the presence of effector cells;
6) modulation (inhibition or enhancement) of NAALADase, folate hydrolase, dipeptidyl peptidase IV and/or 7-glutamyl hydrolase activities;
7) growth inhibition, cell cycle arrest and/or cytotoxicity in the absence of effector cells;
8) internalization of PSMA;
9) binding to a conformational epitope on PSMA;

- 37 -10) minimal cross-reactivity with cells or tissues that do not express PSMA; and 11) preferential binding to dimeric forms of PSMA rather than monomeric forms of PSMA.
Preferred antibodies of the invention meet one or more, and preferably all, of these criteria. In a particular embodiment, the antibodies are used in combination, e.g., as a pharmaceutical composition comprising two or more different anti-PSMA
antibodies or binding fragments thereof. For example, anti-PSMA antibodies having different, but complementary activities can be combined in a single therapy to achieve a desired therapeutic or diagnostic effect. An illustration of this would be a composition containing an anti-PSMA
antibody that mediates highly effective killing of target cells in the presence of effector cells, combined with another anti-PSMA antibody that inhibits the growth of cells expressing PSMA.
In a preferred aspect of the invention, the antibody or antigen-binding fragment thereof binds to a conformational epitope within the extracellular domain of the PSMA
molecule. To determine if the selected human anti-PSMA antibodies bind to conformational epitopes, each antibody can be tested in assays using native protein (e.g., non-denaturing immunoprecipitation, flow cytometric analysis of cell surface binding) and denatured protein (e.g., Western blot, immunoprecipitation of denatured proteins). A comparison of the results will indicate whether the antibodies bind conformational epitopes. Antibodies that bind to native protein but not denatured protein are those antibodies that bind conformational epitopes, and are preferred antibodies.
To determine if the selected human anti-PSMA antibodies bind preferentially (i.e., selectively and/or specifically) to a PSMA dimer, each antibody can be tested in assays (e.g., immunoprecipitation followed by Western blotting) using native dimeric PSMA
protein and dissociated monomeric PSMA protein. A comparison of the results will indicate whether the antibodies bind preferentially to the dimer or to the monomer. Antibodies that bind to the PSMA dimer but not to the monomeric PSMA protein are preferred antibodies.
Preferred antibodies include antibodies that competitively inhibit the specific binding of a second antibody to its target epitope on PSMA. To determine competitive inhibition, a variety of assays known to one of ordinary skill in the art can be employed.
For example, the cross-competition assays set forth in Examples 4 and 21 can be used to determine if an

For example, the cross-competition assays set forth in Examples 4 and 21 can be used to determine if an
- 38 -antibody competitively inhibits binding to PSMA by another antibody. These examples provide cell-based methods employing flow cytometry or solid phase binding analysis. Other assays that evaluate the ability of antibodies to cross-compete for PSMA
molecules that are not expressed on the surface of cells, in solid phase or in solution phase, also can be used.
These assays preferably use the PSMA multimers described herein.
Certain preferred antibodies competitively inhibit the specific binding of a second antibody to its target epitope on PSMA by at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 99%. Inhibition can be assessed at various molar ratios or mass ratios; for example competitive binding experiments can be conducted with a 2-fold, 3-fold, 4-fold, 5-fold, 7-fold, 10-fold or more molar excess of the first antibody over the second antibody.
Other preferred antibodies include antibodies that specifically (i.e., selectively) bind to an epitope on PSMA defined by a second antibody. To determine the epitope, one can use standard epitope mapping methods known in the art. For example, fragments (peptides) of PSMA antigen (preferably synthetic peptides) that bind the second antibody can be used to determine whether a candidate antibody binds the same epitope. For linear epitopes, overlapping peptides of a defined length (e.g., 8 or more amino acids) are synthesized. The peptides preferably are offset by 1 amino acid, such that a series of peptides covering every 8 amino acid fragment of the PSMA protein sequence are prepared. Fewer peptides can be prepared by using larger offsets, e.g., 2 or 3 amino acids. In addition, longer peptides (e.g., 9-, 10- or 11-mers) can be synthesized. Binding of peptides to antibodies can be determined using standard methodologies including surface plasmon resonance (BIACORE; see Example 22) and ELISA assays. For examination of conformational epitopes, larger PSMA
fragments can be used. Other methods that use mass spectrometry to define conformational epitopes have been described and can be used (see, e.g., Baerga-Ortiz et al., Protein Science 11:1300-1308, 2002 and references cited therein). Still other methods for epitope determination are provided in standard laboratory reference works, such as Unit 6.8 ("Phage Display Selection and Analysis of B-cell Epitopes") and Unit 9.8 ("Identification of Antigenic Determinants Using Synthetic Peptide Combinatorial Libraries") of Current Protocols in Immunology, Coligan et al., eds., John Wiley & Sons. Epitopes can be confirmed by introducing point mutations or deletions into a known epitope, and then testing binding with one or more antibodies to determine which mutations reduce binding of the antibodies.

Toxins that are less preferred in the compositions and methods of the invention include poisonous lectins, plant toxins such as ricin, abrin, modeccin, botulina and diphtheria toxins. Of course, combinations of the various toxins could also be coupled to one antibody molecule thereby accommodating variable cytotoxicity. Other chemotherapeutic agents are known to those skilled in the art.

- 41 -The coupling of one or more toxin molecules to the anti-PSMA antibody is envisioned to include many chemical mechanisms, for instance covalent binding, affinity binding, intercalation, coordinate binding, and complexation. The toxic compounds used to prepare the anti-PSMA immunotoxins are attached to the antibodies or PSMA-binding fragments thereof by standard protocols known in the art.
The covalent binding can be achieved either by direct condensation of existing side chains or by the incorporation of external bridging molecules. Many bivalent or polyvalent agents are useful in coupling protein molecules to other proteins, peptides or amine functions, etc. For example, the literature is replete with coupling agents such as carbodiimides, diisocyanates, glutaraldehyde, diazobenzenes, and hexamethylene diamines. This list is not intended to be exhaustive of the various coupling agents known in the art but, rather, is exemplary of the more common coupling agents.
In preferred embodiments, it is contemplated that one may wish to first derivatize the antibody, and then attach the toxin component to the derivatized product.
Suitable cross-linking agents for use in this manner include, for example, SPDP (N-succinimidy1-3-(2-pyridyldithio)propionate), and SMPT, 4-succinimidyl-oxycarbonyl-methyl-(2-pyridyldithio)toluene.
In addition, protein toxins can be fused to the anti-PSMA antibody or PSMA
binding fragment by genetic methods to form a hybrid irnmunotoxin fusion protein. To make a fusion immunotoxin protein in accordance with the invention, a nucleic acid molecule is generated that encodes an anti-PSMA antibody, a fragment of an anti-PSMA antibody, a single chain anti-PSMA antibody, or a subunit of an anti-PSMA antibody linked to a protein toxin. Such fusion proteins contain at least a targeting agent (e.g., anti-PSMA antibody subunit) and a toxin of the invention, operatively attached. The fusion proteins may also include additional peptide sequences, such as peptide spacers which operatively attach the targeting agent and toxin compound, as long as such additional sequences do not appreciably affect the targeting or toxin activities of the fusion protein. The two proteins can be attached by a peptide linker or spacer, such as a glycine-serine spacer peptide, or a peptide hinge, as is well known in the art. Thus, for example, the C-terminus of an anti-PSMA antibody or fragment thereof can be fused to the N-terminus of the protein toxin molecule to form an imrnunotoxin that retains the binding properties of the anti-PSMA antibody. Other fusion arrangements will be known to one of ordinary skill in the art.

Other fusion arrangements will be known to one of ordinary skill in the art.
- 42 -To express the fusion immunotoxin, the nucleic acid encoding the fusion protein is inserted into an expression vector in accordance with standard methods, for stable expression of the fusion protein, preferably in mammalian cells, such as CHO cells. The fusion protein can be isolated and purified from the cells or culture supernatant using standard methodology, such as a PSMA affinity column.
Radionuclides typically are coupled to an antibody by chelation. For example, in the case of metallic radionuclides, a bifunctional chelator is commonly used to link the isotope to the antibody or other protein of interest. Typically, the chelator is first attached to the antibody, and the chelator-antibody conjugate is contacted with the metallic radioisotope. A
number of bifunctional chelators have been developed for this purpose, including the diethylenetriamine pentaacetic acid (DTPA) series of amino acids described in U.S. patents 5,124,471, 5,286,850 and 5,434,287. As another example, hydroxamic acid-based bifunctional chelating agents are described in U.S. patent 5,756,825. Another example is the chelating agent termedp-SCN-Bz-HEHA (1,4,7,10,13,16-hexaazacyclo-octadecane-N,N',N",N"',N",N"'"-hexaacetic acid) (Deal et al., J. Med. Chen2. 42:2988, 1999), which is an effective chelator of radiometals such as 225AC. Yet another example is DOTA
(1,4,7,10-tetraazacyclododecane N,N',N",N"'-tetraacetic acid), which is a bifunctional chelating agent (see McDevitt et al., Science 294:1537-1540, 2001) that can be used in a two-step method for labeling followed by conjugation.
In another aspect, the invention provides compositions comprising an isolated antibody, an antibody derivatized or linked to other functional moieties, or an antigen-binding fragment thereof or a combination of one or more of the aforementioned antibodies or antigen-binding fragments thereof. The compositions include a physiologically or pharmaceutically acceptable carrier, excipient, or stabilizer mixed with the isolated antibody or antigen-binding fragment thereof. In a preferred embodiment, the compositions include a combination of multiple (e.g., two or more) isolated antibodies or antigen-binding portions thereof of the invention. Preferably, each of the antibodies or antigen-binding portions thereof of the composition binds to a distinct conformational epitope of PSMA.
In one embodiment, anti-PSMA antibodies having complementary activities are used in combination, e.g., as a pharmaceutical composition, comprising two or more anti-PSMA
antibodies. For example, an antibody that mediates highly effective cytolysis of target cells
Radionuclides typically are coupled to an antibody by chelation. For example, in the case of metallic radionuclides, a bifunctional chelator is commonly used to link the isotope to the antibody or other protein of interest. Typically, the chelator is first attached to the antibody, and the chelator-antibody conjugate is contacted with the metallic radioisotope. A
number of bifunctional chelators have been developed for this purpose, including the diethylenetriamine pentaacetic acid (DTPA) series of amino acids described in U.S. patents 5,124,471, 5,286,850 and 5,434,287. As another example, hydroxamic acid-based bifunctional chelating agents are described in U.S. patent 5,756,825. Another example is the chelating agent termedp-SCN-Bz-HEHA (1,4,7,10,13,16-hexaazacyclo-octadecane-N,N',N",N"',N",N"'"-hexaacetic acid) (Deal et al., J. Med. Chen2. 42:2988, 1999), which is an effective chelator of radiometals such as 225AC. Yet another example is DOTA
(1,4,7,10-tetraazacyclododecane N,N',N",N"'-tetraacetic acid), which is a bifunctional chelating agent (see McDevitt et al., Science 294:1537-1540, 2001) that can be used in a two-step method for labeling followed by conjugation.
In another aspect, the invention provides compositions comprising an isolated antibody, an antibody derivatized or linked to other functional moieties, or an antigen-binding fragment thereof or a combination of one or more of the aforementioned antibodies or antigen-binding fragments thereof. The compositions include a physiologically or pharmaceutically acceptable carrier, excipient, or stabilizer mixed with the isolated antibody or antigen-binding fragment thereof. In a preferred embodiment, the compositions include a combination of multiple (e.g., two or more) isolated antibodies or antigen-binding portions thereof of the invention. Preferably, each of the antibodies or antigen-binding portions thereof of the composition binds to a distinct conformational epitope of PSMA.
In one embodiment, anti-PSMA antibodies having complementary activities are used in combination, e.g., as a pharmaceutical composition, comprising two or more anti-PSMA

As used herein, "target cell" shall mean any undesirable cell in a subject (e.g., a human or animal) that can be targeted by a composition of the invention. In preferred embodiments, the target cell is a cell expressing or overexpressing PSMA.
Pharmaceutical compositions of the invention also can be administered in combination therapy, i.e., combined with other agents. For example, the combination therapy can include a composition of the present invention with at least one anti-tumor agent, immunomodulator, immunostimulatory agent, or other conventional therapy. The agent may be bound or conjugated to or formed as a recombinant fusion molecule with the PSMA =
antibodies of the present invention for directed targeting of the agent to PSMA-expressing cells.
The PSMA antibodies of the present invention may be used as a targeting moiety for delivery of replication-selective virus to PSMA-expressing cells for tumor therapy.

As used herein, "pharmaceutically acceptable carrier" or "physiologically acceptable carrier" includes any and all salts, solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like that are physiologically compatible. Preferably, the carrier is suitable for intravenous, intramuscular, subcutaneous, parenteral, spinal or epidermal administration (e.g., by injection or infusion).
Depending on the route of administration, the active compound, i.e., antibody may be coated in a material to protect the compound from the action of acids and other natural conditions that may inactivate the compound.
When administered, the pharmaceutical preparations of the invention are applied in pharmaceutically-acceptable amounts and in pharmaceutically-acceptable compositions.. The term "pharmaceutically acceptable" means a non-toxic material that does not interfere with the effectiveness of the biological activity of the active ingredients.

- 44 -adjuvants, chemokines and cytokines. When used in medicine, the salts should be pharmaceutically acceptable, but non-pharmaceutically acceptable salts may conveniently be used to prepare pharmaceutically-acceptable salts thereof and are not excluded from the scope of the invention.
A salt retains the desired biological activity of the parent compound and does not impart any undesired toxicological effects (see e.g., Berge, S.M., et al.
(1977)1 Pharm. Sci.
66: 1-19). Examples of such salts include acid addition salts and base addition salts. Acid addition salts include those derived from nontoxic inorganic acids, such as hydrochloric, nitric, phosphoric, sulfuric, hydrobromic, hydroiodic, phosphorous and the like, as well as from nontoxic organic acids such as aliphatic mono- and dicarboxylic acids, phenyl substituted alkanoic acids, hydroxy alkanoic acids, aromatic acids, aliphatic and aromatic sulfonic acids and the like.

An anti-PSMA antibody composition may be combined, if desired, with a pharmaceutically-acceptable carrier. The term "pharmaceutically-acceptable carrier" as used herein means one or more compatible solid or liquid fillers, diluents or encapsulating substances which are suitable for administration into a human. The term "carrier" denotes an organic or inorganic ingredient, natural or synthetic, with which the active ingredient is combined to facilitate the application. The components of the pharmaceutical compositions also are capable of being co-mingled with the molecules of the present invention, and with each other, in a manner such that there is no interaction which would substantially impair the desired pharmaceutical efficacy.
The pharmaceutical compositions may contain suitable buffering agents, including:
acetic acid in a salt; citric acid in a salt; boric acid in a salt; and phosphoric acid in a salt.
The pharmaceutical compositions also may contain, optionally, suitable preservatives, such as: benzalkonium chloride; chlorobutanol; parabens and thimerosal.
The pharmaceutical compositions may conveniently be presented in unit dosage form and may be prepared by any of the methods well-known in the art of pharmacy.
All methods include the step of bringing the active agent into association with a carrier which constitutes one or more accessory ingredients. In general, the compositions are prepared by uniformly

-45 -and intimately bringing the active compound into association with a liquid carrier, a finely divided solid carrier, or both, and then, if necessary, shaping the product.
Compositions suitable for parenteral administration conveniently comprise a sterile aqueous or non-aqueous preparation of anti-PSMA antibodies, which is preferably isotonic with the blood of the recipient. This preparation may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation also may be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butane diol.
Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono-or di-glycerides. In addition, fatty acids such as oleic acid may be used in the preparation of injectables. Carrier formulations suitable for oral, subcutaneous, intravenous, intramuscular, etc. administration can be found in Remington 's Pharmaceutical Sciences, Mack Publishing Co., Easton, PA.
The active compounds can be prepared with carriers that will protect the compound against rapid release, such as a controlled release formulation, including implants, transdermal patches, and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Many methods for the preparation of such formulations are patented or generally known to those skilled in the art. See, e.g., Sustained and Controlled Release Drug Delivery Systems, J.R. Robinson, ed., Marcel Dekker, Inc., New York, 1978.
The therapeutics of the invention can be administered by any conventional route, including injection or by gradual infusion over time. The administration may, for example, be oral, intravenous, intraperitoneal, intramuscular, intracavity, intratumor, or transdermal.
When antibodies are used therapeutically, preferred routes of administration include intravenous and by pulmonary aerosol. Techniques for preparing aerosol delivery systems containing antibodies are well known to those of skill in the art. Generally, such systems should utilize components which will not significantly impair the biological properties of the antibodies, such as the paratope binding capacity (see, for example, Sciarra and Cutie, "Aerosols," in Remington's Pharmaceutical Sciences, 18th edition, 1990, pp.

The compositions of the invention are administered in effective amounts. An "effective amount" is that amount of an anti-PSMA antibody composition that alone, or together with further doses, produces the desired response, e.g. treats a malignancy in a subject. This may involve only slowing the progression of the disease temporarily, although more preferably, it involves halting the progression of the disease permanently. This can be monitored by routine methods. The desired response to treatment of the disease or condition also can be delaying the onset or even preventing the onset of the disease or condition.
Such amounts will depend, of course, on the particular condition being treated, the severity of the condition, the individual patient parameters including age, physical condition, size and weight, the duration of the treatment, the nature of concurrent therapy (if any), the specific route of administration and like factors within the knowledge and expertise of the health practitioner. These factors are well known to those of ordinary skill in the art and can be addressed with no more than routine experimentation. R is generally preferred that a maximum dose of the individual components or combinations thereof be used, that is, the highest safe dose according to sound medical judgment. It will be understood by those of ordinary skill in the art, however, that a patient may insist upon a lower dose or tolerable dose for medical reasons, psychological reasons or for virtually any other reasons.
The pharmaceutical compositions used in the foregoing methods preferably are sterile and contain an effective amount of anti-PSMA antibodies for producing the desired response in a unit of weight or volume suitable for administration to a patient. The response can, for example, be measured by determining the physiological effects of the anti-PSMA
antibody composition, such as regression of a tumor or decrease of disease symptoms.
Other assays will be known to one of ordinary skill in the art and can be employed for measuring the level of the response.
The doses of anti-PSMA antibodies administered to a subject can be chosen in accordance with different parameters, in particular in accordance with the mode of administration used and the state of the subject. Other factors include the desired period of treatment. In the event that a response in a subject is insufficient at the initial doses applied,

-47 -higher doses (or effectively higher doses by a different, more localized delivery route) may be employed to the extent that patient tolerance permits.
In general, doses can range from about 10 1.1g/kg to about 100,000 Kg/kg.
Based upon the composition, the dose can be delivered continuously, such as by continuous pump, or at periodic intervals. Desired time intervals of multiple doses of a particular composition can be determined without undue experimentation by one skilled in the art. Other protocols for the administration of anti-PSMA antibody compositions will be known to one of ordinary skill in the art, in which the dose amount, schedule of administration, sites of administration, mode of administration and the like vary from the foregoing.
In general, doses of radionuclide delivered by the anti-PSMA antibodies of the invention can range from about 0.01 mCi/Kg to about 10 mCi/kg. Preferably the dose of radionuclide ranges from about 0.1 mCi/Kg to about 1.0 mCi/kg. The optimal dose of a given isotope can be determined empirically by simple routine titration experiments well known to one of ordinary skill in the art.
Administration of anti-PSMA antibody compositions to mammals other than humans, e.g. for testing purposes or veterinary therapeutic purposes, is carried out under substantially the same conditions as described above.
The compositions (antibodies to PSMA and derivatives/conjugates thereof) of the present invention have in vitro and in vivo diagnostic and therapeutic utilities. For example, these molecules can be administered to cells in culture, e.g. in vitro or ex vivo, or in a subject, e.g., in vivo, to treat, prevent or diagnose a variety of disorders. As used herein, the term "subject" is intended to include humans and non-human animals. Preferred subjects include a human patient having a disorder characterized by expression, typically aberrant expression (e.g., overexpression) of PSMA.
One aspect of the present invention relates to a method of detecting cancerous cells or portions thereof in a biological sample (e.g., histological or cytological specimens, biopsies and the like), and, in particular, to distinguish malignant tumors from normal tissues and non-malignant tumors. This method involves providing an antibody or an antigen-binding binding fragment thereof, probe, or ligand, which binds to an extracellular domain of PSMA
of such cells, e.g., an anti-PSMA antibody. The anti-PSMA antibody is bound to a label that permits the detection of the cells or portions thereof (e.g., PSMA or fragments thereof liberated from such cancerous cells) upon binding of the anti-PSMA antibody to the cells or

This method involves providing an antibody or an antigen-binding binding fragment thereof, probe, or ligand, which binds to an extracellular domain of PSMA
of such cells, e.g., an anti-PSMA antibody. The anti-PSMA antibody is bound to a label that permits the detection of the cells or portions thereof (e.g., PSMA or fragments thereof liberated from such cancerous cells) upon binding of the anti-PSMA antibody to the cells or
-48 -portions thereof. The biological sample is contacted with the labeled anti-PSMA antibody under conditions effective to permit binding of the anti-PSMA antibody to the extracellular domain of PSMA of any of the cells or portions thereof in the biological sample. The presence of any cells or portions thereof in the biological sample is detected by detection of the label. In one preferred form, the contact between the anti-PSMA antibody and the biological sample is carried out in a living mammal and involves administering the anti-PSMA antibody to the mammal under conditions that permit binding of the anti-PSMA
antibody to PSMA of any of the cells or portions thereof in the biological sample. Again, such administration can be carried out by any suitable method known to one of ordinary skill in the art.
In addition, the anti-PSMA antibodies of the present invention can be used in immunofluorescence techniques to examine human tissue, cell and bodily fluid specimens. In a typical protocol, slides containing cryostat sections of frozen, unfixed tissue biopsy samples or cytological smears are air dried, formalin or acetone fixed, and incubated with the monoclonal antibody preparation in a humidified chamber at room temperature.
The slides are then washed and further incubated with a preparation of a secondary antibody directed against the monoclonal antibody, usually some type of anti-mouse immunoglobulin if the monoclonal antibodies used are derived from the fusion of a mouse spleen lymphocyte and a mouse myeloma cell line. This secondary antibody is tagged with a compound, for instance rhodamine or fluorescein isothiocyanate, that fluoresces at a particular wavelength. The staining pattern and intensities within the sample are then determined by fluorescent light microscopy and optionally photographically recorded.
As yet another alternative, computer enhanced fluorescence image analysis or flow cytometry can be used to examine tissue specimens or exfoliated cells, i.e., single cell preparations from aspiration biopsies of tumors using the anti-PSMA antibodies of this invention. The anti-PSMA antibodies of the invention are particularly useful in quantitation of live tumor cells, i.e., single cell preparations from aspiration biopsies of prostate tumors by computer enhanced fluorescence image analyzer or with a flow cytometer.

The percent PSMA positive cell population, alone or in conjunction with determination of other
- 49 -attributes of the cells (e.g., DNA ploidy of these cells), may, additionally, provide very useful prognostic information by providing an early indicator of disease progression.
In yet another alternative embodiment, the antibodies of the present invention can be used in combination with other known antibodies to provide additional information regarding the malignant phenotype of a cancer.
The method of the present invention can be Used to screen patients for diseases associated with the presence of cancerous cells or portions thereof.
Alternatively, it can be used to identify the recurrence of such diseases, particularly when the disease is localized in a particular biological material of the patient. For example, recurrence of prostatic disease in the prostatic fossa may be encountered following radical prostatectomy. Using the method of the present invention, this recurrence can be detected by administering a short range radiolabeled antibody to the mammal and then detecting the label rectally, such as with a transrectal detector probe.
Alternatively, the contacting step can be carried out in a sample of serum or urine or other body fluids, including but not limited to seminal fluid, prostatic fluid, ejaculate, and the like, such as to detect the presence of PSMA in the body fluid. When the contacting is carried out in a serum or urine sample, it is preferred that the biological agent recognize substantially no antigens circulating in the blood other than PSMA. Since intact cells do not excrete or secrete PSMA into the extracellular environment, detecting PSMA in serum, urine, or other body fluids generally indicates that cells are being lysed or shed.
Thus, the biological agents and methods of the present invention can be used to determine the effectiveness of a cancer treatment protocol by monitoring the level of PSMA
in serum, urine or other body fluids.
In a particularly preferred embodiment of the method of detecting cancerous cells in accordance with the present invention, the anti-PSMA antibodies or an antigen-binding fragment thereof, binds to and is internalized with the prostate specific membrane antigen of such cells. Again, the biological agent is bound to a label effective to permit detection of the cells or portions thereof upon binding of the biological agent to and internalization of the biological agent with the prostate specific membrane antigen.

Again, the biological agent is bound to a label effective to permit detection of the cells or portions thereof upon binding of the biological agent to and internalization of the biological agent with the prostate specific membrane antigen.
Biological agents suitable for detecting cancerous cells include anti-PSMA
antibodies, such as monoclonal or polyclonal antibodies. In addition, antibody fragments, half-antibodies, hybrid derivatives, probes, and other molecular constructs may be utilized. These
- 50 -biological agents, such as antibodies, antigen-binding fragments thereof, probes, or ligands, bind to extracellular domains of prostate specific membrane antigens or portions thereof in cancerous cells. As a result, the biological agents bind not only to cells which are fixed or cells whose intracellular antigenic domains are otherwise exposed to the extracellular environment. Consequently, binding of the biological agents is concentrated in areas where there are prostate cells, irrespective of whether these cells are fixed or unfixed, viable or necrotic. Additionally or alternatively, these biological agents bind to and are internalized with prostate specific membrane antigens or portions thereof in normal, benign hyperplastic, and to a greater degree in cancerous cells.
The antibodies or antigen-binding fragments thereof can also be utilized in in vivo therapy of cancer. The antibodies can be used alone or covalently attached, either directly or via linker, to a compound which kills and/or inhibits proliferation of the malignant cells or tissues following administration and localization of the conjugates. When the antibody is used by itself, it may mediate tumor destruction by complement fixation or antibody-dependent cellular cytotoxicity. Alternatively, the antibody may be administered in combination with a chemotherapeutic drug to result in synergistic therapeutic effects (Baslya and Mendelsohn, 1994 Breast Cancer Res. and Treatment 29:127-138). A variety of , different types of substances can be directly conjugated to the antibody for therapeutic uses, including radioactive metal and non-metal isotopes, chemotherapeutic drugs, toxins, etc. as described above and known in the art (see, e.g., Vitetta and Uhr, 1985, Annu.

The antibodies or antigen-binding fragments thereof of the invention can also be administered together with complement. Accordingly, within the scope of the invention are compositions comprising antibodies or antigen-binding fragments thereof and serum or complement. These compositions are advantageous in that the complement is located in close proximity to the human antibodies or antigen-binding fragments thereof.
Alternatively, the antibodies or antigen-binding fragments thereof of the invention and the complement or serum can be administered separately.

Antigens, such as the PSMA dimers described herein, can be administered with one or more adjuvants to induce or enhance an immune response. An adjuvant is a substance which potentiates the immune response. Adjuvants of many kinds are well known in the art.
Specific examples of adjuvants include monophosphoryl lipid A (MPL, SmithKline Beecham); saponins including QS21 (SmithKline Beecham); immunostimulatory oligonucleotides (e.g., CpG oligonucleotides described by Kreig et al., Nature 374:546-9, 1995);incomplete Freund's adjuvant; complete Freund's adjuvant; montanide;
vitamin E and various water-in-oil emulsions prepared from biodegradable oils such as squalene and/or tocopherol, Quil A, Ribi Detox, CRL-1005, L-121, and combinations thereof.
Other agents which stimulate the immune response of the subject to PSMA
multimer antigens can also be administered to the subject. For example, cytokines are also useful in vaccination protocols as a result of their lymphocyte regulatory properties.
Many cytoldnes useful for such purposes will be known to one of ordinary skill in the art, including interleukin-2 (IL-2); IL-4; IL-5; IL-12, which has been shown to enhance the protective effects of vaccines (see, e.g., Science 268: 1432-1434, 1995); GM-CSF; IL-15;
IL-18;
combinations thereof, and the like. Thus cytoldnes can be administered in conjunction with antibodies, antigens, chemokines and/or adjuvants to increase an immune response.
Chemokines useful in increasing immune responses include but are not limited to SLC, ELC, MIP3a, MIP313, IP-10, MIG, and combinations thereof.
The antibodies or antigen-binding fragments thereof of the present invention can be used in conjunction with other therapeutic treatment modalities. Such other treatments include surgery, radiation, cryosurgery, thermotherapy, hormone treatment, chemotherapy, vaccines, and other immunotherapies.
Also encompassed by the present invention is a method which involves using the antibodies or antigen-binding fragments thereof for prophylaxis. For example, these materials can be used to prevent or delay development or progression of cancer.
Use of the cancer therapy of the present invention has a number of benefits.
Since the anti-PSMA antibodies or antigen-binding fragments thereof according to the present invention preferentially target prostate cancer cells, other tissue is spared.
As a result, treatment with such biological agents is safer, particularly for elderly patients. Treatment

Since the anti-PSMA antibodies or antigen-binding fragments thereof according to the present invention preferentially target prostate cancer cells, other tissue is spared.
As a result, treatment with such biological agents is safer, particularly for elderly patients. Treatment
- 52 -according to the present invention is expected to be particularly effective, because it directs high levels of anti-PSMA antibodies or antigen-binding fragments thereof to the bone marrow and lymph nodes where prostate cancer metastases predominate. Moreover, tumor sites for prostate cancer tend to be small in size and, therefore, easily destroyed by cytotoxic agents. Treatment in accordance with the present invention can be effectively monitored with clinical parameters such as serum prostate specific antigen and/or pathological features of a patient's cancer, including stage, Gleason score, extracapsular, seminal, vesicle or perineural invasion, positive margins, involved lymph nodes, etc. Alternatively, these parameters can be used to indicate when such treatment should be employed.
Because the antibodies or antigen-binding fragments thereof of the present invention bind to living cells, therapeutic methods using these biological agents are much more effective than those which target lysed cells. For the same reasons, diagnostic and imaging methods which determine the location of living normal, benign hyperplastic, or cancerous cells are much improved by employing the antibodies or antigen-binding fragments thereof of the present invention. In addition, the ability to differentiate between living and dead cells can be advantageous, especially to monitor the effectiveness of a particular treatment regimen.
Also within the scope of the invention are kits comprising the compositions of the invention and instructions for use. The kits can further contain at least one additional reagent, such as complement, or one or more additional antibodies of the invention (e.g., an antibody having a complementary activity which binds to an epitope in PSMA
antigen distinct from the first antibody). Other kits can include the PSMA multimers described hereinbelow.
Kits containing the antibodies or antigen-binding fragments thereof of the invention can be prepared for in vitro diagnosis, prognosis and/or monitoring cancer by the immunohistological, immunocytological and immunoserological methods described above.
The components of the kits can be packaged either in aqueous medium or in lyophilized form. When the antibodies or antigen-binding fragments thereof are used in the kits in the form of conjugates in which a label moiety is attached, such as an enzyme or a radioactive metal ion, the components of such conjugates can be supplied either in fully conjugated form, in the form of intermediates or as separate moieties to be conjugated by the user or the kit.

antibodies (or fragment thereof).

In one aspect of the invention, a method for modulating at least one enzymatic activity of PSMA, the activity selected from the group consisting of N-acetylated a-linked acidic dipeptidase (NAALADase), folate hydrolase, dipeptidyl dipeptidase IV
and y-glutamyl hydrolase activity or combination thereof in vitro or in vivo. The modulation may be enhancement or inhibition of at least one enzymatic activity of PSMA.
In a preferred embodiment, the invention provides methods for inhibiting at least one enzymatic activity of PSMA, the activity selected from the group consisting of N-acetylated a-linked acidic dipeptidase (NAALADase), folate hydrolase, dipeptidyl dipeptidase IV and y-glutamyl hydrolase activity or combination thereof in vitro or in vivo. The method comprises contacting a NAALADase, a folate hydrolase, a dipeptidyl dipeptidase IV and/or a y-glutamyl hydrolase with an amount of an isolated antibody or antigen-binding fragment thereof of the invention under conditions wherein the isolated monoclonal antibody or antigen-binding fragment thereof inhibits NAALADase, folate hydrolase, dipeptidyl dipeptidase IV or y-glutamyl hydrolase activity.
Tissue levels of NAALADase can be determined by detergent solubilizing homogenizing tissues, pelleting the insoluble material by centrifugation and measuring the NAALADase activity in the remaining supernatant. Likewise, the NAALADase activity in
antibodies (or fragment thereof).

Tissue levels of NAALADase can be determined by detergent solubilizing homogenizing tissues, pelleting the insoluble material by centrifugation and measuring the NAALADase activity in the remaining supernatant. Likewise, the NAALADase activity in
- 54 -bodily fluids can also be measured by first pelleting the cellular material by centrifugation and performing a typical enzyme assay for NAALADase activity on the supernatant.
NAALADase enzyme assays have been described by Frieden, 1959, J. Biol, Chem., 234:2891. In this assay, the reaction product of the NAALADase enzyme is glutamic acid.
This is derived from the enzyme catalyzed cleavage of N-acetylaspartylglutamate to yield N-acetylaspartic acid and glutamic acid. Glutamic acid, in a NAD(P)+ requiring step, yields 2-oxoglutarate plus NAD(P)H in a reaction catalyzed by glutamate dehydrogenase.
Progress of the reaction can easily and conveniently be measured by the change in absorbance at 340 nm due to the conversion of NAD(P)+ to NAD(P)H.
Folate hydrolase activity of PSMA can be measured by performing enzyme assays as described by Heston and others (e.g., Clin. Cancer Res. 2(9):1445-51, 1996;
Urology 49(3A
Suppl):104-12,1997). Folate hydrolases such as PSMA remove the gamma-linked glutamates from polyglutamated folates. Folate hydrolase activity can be measured using substrates such as rnethotrexate tri-gamma glutamate (MTXG1u3), methotrexate di-gamma glutamate (MTXG1u2) and pteroylpentaglutamate (PteGlu5), for example using capillary electrophoresis (see Clin. Cancer Res. 2(9):1445-51, 1996). Timed incubations of PSMA
with polyglutamated substrates is followed by separation and detection of hydrolysis products.
The invention also includes isolated antibodies and binding fragments thereof that selectively bind PSMA multimers. As used herein, particularly with respect to the binding of PSMA multimers by the anti-PSMA antibodies and binding fragments, "selectively binds"
means that an antibody preferentially binds to a PSMA protein multimer (e.g., with greater avidity, greater binding affinity) rather than to a PSMA protein monomer. In preferred embodiments, the antibodies of the invention bind to a PSMA protein multimer with an avidity and/or binding affinity that is 1.1-fold, 1.2-fold, 1.3-fold, 1.4-fold, 1.5-fold, 1.6-fold, 1.7-fold, 1.8-fold, 1.9-fold, 2-fold, 3-fold, 4-fold, 5-fold, 7-fold, 10-fold, 20-fold, 30-fold, 40-fold, 50-fold, 70-fold, 100-fold, 200-fold, 300-fold, 500-fold, 1000-fold or more than that exhibited by the antibody for a PSMA protein monomer. Preferably, the antibody selectively binds a PSMA protein multimer, and not a PSMA protein monomer, i.e., substantially exclusively binds to a PSMA protein multimer. Most preferably, the antibody selectively binds a PSMA protein dimer.

Preferably, the antibody selectively binds a PSMA protein multimer, and not a PSMA protein monomer, i.e., substantially exclusively binds to a PSMA protein multimer. Most preferably, the antibody selectively binds a PSMA protein dimer.
- 55 -The isolated antibody or binding fragment that selectively binds a PSMA
protein multimer can, in some embodiments, modulate enzymatic activity of the PSMA
protein multimer. In one such embodiment, the antibody inhibits at least one enzymatic activity such as NAALADase activity, folate hydrolase activity, dipeptidyl dip eptidase IV
activity, y-glutamyl hydrolase activity, or combinations thereof. In another embodiment, the antibody enhances at least one enzymatic activity such as NAALADase activity, folate hydrolase activity, dipeptidyl dipeptidase IV activity, y-glutamyl hydrolase activity, or combinations thereof.
A PSMA protein multimer, as used herein, is a protein complex of at least two PSMA
proteins or fragments thereof. The PSMA protein multimers can be composed of various combinations of full-length PSMA proteins (e.g., SEQ ID NO:1), recombinant soluble PSMA
(rsPSMA, e.g., amino acids 44-750 of SEQ ID NO:1) and fragments of the foregoing that form multimers (i.e., that retain the protein domain required for forming dimers and/or higher order multimers of PSMA). In preferred embodiments, at least one of the PSMA
proteins forming the multimer is a recombinant, soluble PSMA (rsPSMA) polypeptide.
Preferred PSMA protein multimers are dimers, particularly those formed from recombinant soluble PSMA protein. A particularly preferred embodiment is a rsPSMA homodimer.
The PSMA protein multimers referred to herein are believed to assume a native conformation and preferably have such a conformation. The PSMA proteins in certain embodiments are noncovalently bound together to form the PSMA protein multimer. For example, it has been discovered that PSMA protein noncovalently associates to form dimers under non-denaturing conditions, as described in the Examples below.
The PSMA protein multimers can, and preferably do, retain the activities of PSMA.
The PSMA activity may be an enzymatic activity, such as folate hydrolase activity, NAALADase activity, dipeptidyl peptidase IV activity and y-glutamyl hydrolase activity.
Methods for testing the PSMA activity of multimers are well known in the art (reviewed by O'Keefe et al. in: Prostate Cancer: Biology, Genetics, and the New Therapeutics, L.W.K.
Chung, W.B. Isaacs and J.W. Simons (eds.) Humana Press, Totowa, NJ, 2000, pp.
307-326), some of which are described in the Examples herein below.
In certain aspects, the invention also includes compositions including one or more of the isolated PSMA protein multimers described herein, such as the PSMA protein dimer. In preferred embodiments, a PSMA protein multimer composition contains at least about 10%
protein multimer can, in some embodiments, modulate enzymatic activity of the PSMA
protein multimer. In one such embodiment, the antibody inhibits at least one enzymatic activity such as NAALADase activity, folate hydrolase activity, dipeptidyl dip eptidase IV
activity, y-glutamyl hydrolase activity, or combinations thereof. In another embodiment, the antibody enhances at least one enzymatic activity such as NAALADase activity, folate hydrolase activity, dipeptidyl dipeptidase IV activity, y-glutamyl hydrolase activity, or combinations thereof.

In certain aspects, the invention also includes compositions including one or more of the isolated PSMA protein multimers described herein, such as the PSMA protein dimer. In preferred embodiments, a PSMA protein multimer composition contains at least about 10%
-56-.
PSMA protein multimer. In other embodiments, the PSMA protein multimer composition contains at least about 20%, 30%, 40%, 50%, 60%, 70%, 75%, 80%, 85%, 90%, 95%, 99%
or 99.5% PSMA protein multimer. In a preferred embodiment, the PSMA protein multimer composition contains substantially pure PSMA protein multimer, with substantially no PSMA protein monomer. It is understood that the list of specific percentages includes by inference all of the unnamed percentages between the recited percentages.
As used herein with respect to polypeptides, proteins or fragments thereof, "isolated"
means separated from its native environment and present in sufficient quantity to permit its identification or use. Isolated, when referring to a protein or polypeptide, means, for example: (i) selectively produced by expression cloning or (ii) purified as by chromatography or electrophoresis. Isolated proteins or polypeptides may be, but need not be, substantially pure. The term "substantially pure" means that the proteins or polypeptides are essentially free of other substances with which they may be found in nature or in vivo systems to an extent practical and appropriate for their intended use.
Substantially pure polypeptides may be produced by techniques well known in the art. Because an isolated protein may be admixed with a pharmaceutically acceptable carrier in a pharmaceutical preparation, the protein may comprise only a small percentage by weight of the preparation.
The protein is nonetheless isolated in that it has been separated from the substances with which it may be associated in living systems, i.e. isolated from other proteins.
Fragments of a PSMA protein preferably are those fragments which retain a distinct functional capability of the PSMA protein. Functional capabilities which can be retained in a fragment include binding of other PSMA molecules to form dimers and higher order multimers, interaction with antibodies, interaction with other polypeptides or fragments thereof, and enzymatic activity. Other PSMA protein fragments, e.g., other recombinant soluble fragments of SEQ ID NO:1, can be selected according to their functional properties.
For example, one of ordinary skill in the art can prepare PSMA fragments recombinantly and test those fragments according to the methods exemplified below.
Modifications to a PSMA polypeptide are typically made to the nucleic acid which encodes the PSMA polypeptide, and can include deletions, point mutations, truncations, amino acid substitutions and additions of amino acids or non-amino acid moieties.
Alternatively, modifications can be made directly to the polypeptide, such as by cleavage, addition of a linker molecule, addition of a detectable moiety, such as biotin, addition of a
PSMA protein multimer. In other embodiments, the PSMA protein multimer composition contains at least about 20%, 30%, 40%, 50%, 60%, 70%, 75%, 80%, 85%, 90%, 95%, 99%
or 99.5% PSMA protein multimer. In a preferred embodiment, the PSMA protein multimer composition contains substantially pure PSMA protein multimer, with substantially no PSMA protein monomer.

Modifications to a PSMA polypeptide are typically made to the nucleic acid which encodes the PSMA polypeptide, and can include deletions, point mutations, truncations, amino acid substitutions and additions of amino acids or non-amino acid moieties.
Alternatively, modifications can be made directly to the polypeptide, such as by cleavage, addition of a linker molecule, addition of a detectable moiety, such as biotin, addition of a
- 57 -fatty acid, and the like. Modifications also embrace fusion proteins comprising all or part of the PSMA amino acid sequence.
In general, modified PSMA polypeptides include polypeptides which are modified specifically to alter a feature of the polypeptide unrelated to its physiological activity. For example, cysteine residues can be substituted or deleted to prevent unwanted disulfide linkages. Similarly, certain amino acids can be changed to enhance expression of a PSMA
polypeptide by eliminating proteolysis by proteases in an expression system (e.g., dibasic amino acid residues in yeast expression systems in which KEX2 protease activity is present).
Modifications conveniently are prepared by altering a nucleic acid molecule that encodes the PSMA polypeptide. Mutations of a nucleic acid which encode a PSMA
polypeptide preferably preserve the amino acid reading frame of the coding sequence, and preferably do not create regions in the nucleic acid which are likely to hybridize to form secondary structures, such a hairpins or loops, which can be deleterious to expression of the modified polypeptide.
Modifications can be made by selecting an amino acid substitution, or by random mutagenesis of a selected site in a nucleic acid which encodes the PSMA
polypeptide.
Modified PSMA polypeptides then can be expressed and tested for one or more activities (e.g., antibody binding, enzymatic activity, multimeric stability) to determine which mutation provides a modified polypeptide with the desired properties. Further mutations can be made to modified PSMA polypeptides (or to non-modified PSMA polypeptides) which are silent as to the amino acid sequence of the polypeptide, but which provide preferred codons for translation in a particular host. The preferred codons for translation of a nucleic acid in, e.g., E. coil, are well known to those of ordinary skill in the art. Still other mutations can be made to the noncoding sequences of a PSMA coding sequence or cDNA clone to enhance expression of the polypeptide. The activity of modified PSMA polypeptides can be tested by cloning the gene encoding the modified PSMA polypeptide into a bacterial or mammalian expression vector, introducing the vector into an appropriate host cell, expressing the modified PSMA polypeptide, and testing for a functional capability of the PSMA
polypeptides as disclosed herein. The foregoing procedures are well known to one of ordinary skill in the art.
The skilled artisan will also realize that conservative amino acid substitutions may be made in PSMA polypeptides to provide functionally equivalent PSMA
polypeptides, i.e.,
In general, modified PSMA polypeptides include polypeptides which are modified specifically to alter a feature of the polypeptide unrelated to its physiological activity. For example, cysteine residues can be substituted or deleted to prevent unwanted disulfide linkages. Similarly, certain amino acids can be changed to enhance expression of a PSMA
polypeptide by eliminating proteolysis by proteases in an expression system (e.g., dibasic amino acid residues in yeast expression systems in which KEX2 protease activity is present).
Modifications conveniently are prepared by altering a nucleic acid molecule that encodes the PSMA polypeptide. Mutations of a nucleic acid which encode a PSMA
polypeptide preferably preserve the amino acid reading frame of the coding sequence, and preferably do not create regions in the nucleic acid which are likely to hybridize to form secondary structures, such a hairpins or loops, which can be deleterious to expression of the modified polypeptide.
Modifications can be made by selecting an amino acid substitution, or by random mutagenesis of a selected site in a nucleic acid which encodes the PSMA
polypeptide.
Modified PSMA polypeptides then can be expressed and tested for one or more activities (e.g., antibody binding, enzymatic activity, multimeric stability) to determine which mutation provides a modified polypeptide with the desired properties. Further mutations can be made to modified PSMA polypeptides (or to non-modified PSMA polypeptides) which are silent as to the amino acid sequence of the polypeptide, but which provide preferred codons for translation in a particular host. The preferred codons for translation of a nucleic acid in, e.g., E. coil, are well known to those of ordinary skill in the art. Still other mutations can be made to the noncoding sequences of a PSMA coding sequence or cDNA clone to enhance expression of the polypeptide. The activity of modified PSMA polypeptides can be tested by cloning the gene encoding the modified PSMA polypeptide into a bacterial or mammalian expression vector, introducing the vector into an appropriate host cell, expressing the modified PSMA polypeptide, and testing for a functional capability of the PSMA

As used herein, a "conservative amino acid substitution" refers to an amino acid substitution which does not alter the relative charge or size characteristics of the protein in which the amino acid substitution is made. Modified PSMA polypeptides can be prepared according to methods for altering polypeptide sequence known to one of ordinary skill in the art such as are found in references which compile such methods, e.g. Molecular Cloning: A

Ausubel, et al., eds., John Wiley & Sons, Inc., New York. Exemplary functionally equivalent PSMA polypeptides include conservative amino acid substitutions of SEQ lD
NO:1, or fragments thereof, such as the recombinant soluble PSMA polypeptide (amino acids 44-750 of SEQ ID NO:1). Conservative substitutions of amino acids include substitutions made amongst amino acids within the following groups: (a) M, I, L, V; (b) F, Y, W; (e) K, R, H; (d) A, G; (e) S, T; (f) Q, N; and (g) E, D.
Conservative amino-acid substitutions in PSMA polypeptides typically are made by alteration of a nucleic acid encoding a PSMA polypeptide. Such substitutions can be made by a variety of methods known to one of ordinary skill in the art. For example, amino acid substitutions may be made by PCR-directed mutation, site-directed mutagenesis, or by chemical synthesis of a gene encoding a PSMA polypeptide. Where amino acid substitutions are made to a small fragment of a PSMA polypeptide, the substitutions can be made by directly synthesizing the peptide. The activity of functionally equivalent fragments of PSMA
polypeptides can be tested by cloning the gene encoding the altered PSMA
polypeptide into a bacterial or mammalian expression vector, introducing the vector into an appropriate host cell, expressing the altered PSMA polypeptide, and testing for a functional capability of the PSMA polypeptides as disclosed herein.
The PSMA protein multimers as described herein have a number of uses, some of which are described elsewhere herein. The multimers are useful for testing of compounds that modulate PSMA enzymatic activity or PSMA multimerization. The multimers can be used to isolate antibodies that selectively bind PSMA, including those selective for conformational epitopes, those selective for binding PSMA multimers and not PSMA
monomers, and those that selectively modulate an enzymatic activity of PSMA.

The
- 59 -multimers, particularly dimeric PSMA, also can be used to induce or increase immune responses to PSMA, as vaccine compositions.
Agents that selectively modulate an enzymatic activity of PSMA include agents that inhibit or enhance at least one enzymatic activity of PSMA, such as NAALADase activity, folate hydrolase activity, dipeptidyl dipeptidase IV activity, y-glutamyl hydrolase activity, or combinations thereof.
Thus methods of screening for candidate agents that modulate at least one enzymatic activity of a PSMA enzyme are provided in accordance with the invention. The methods can include mixing the candidate agent with an isolated PSMA protein multimer to form a reaction mixture, thereby contacting the PSMA enzyme with the candidate agent.
The methods also include adding a substrate for the PSMA enzyme to the reaction mixture, and determining the amount of a product formed from the substrate by the PSMA
enzyme. Such methods are adaptable to automated, high-throughput screening of compounds. A
decrease in the amount of product formed in comparison to a control is indicative of an agent capable of inhibiting at least one enzymatic activity of the PSMA enzyme. An increase in the amount of product formed in comparison to a control is indicative of an agent capable of enhancing at least one enzymatic activity of the PSMA enzyme. The PSMA enzyme can be NAALADase, folate hydrolase, dipeptidyl dipeptidase IV and/or y-glutamyl hydrolase. The PSMA enzyme preferably is a PSMA multimer that includes recombinant soluble PSMA, most preferably a noncovalently associated dimer of PSMA in a native conformation.
The reaction mixture comprises a candidate agent. The candidate agent is preferably an antibody, a small organic compound, or a peptide, and accordingly can be selected from combinatorial antibody libraries, combinatorial protein libraries, or small organic molecule libraries. Typically, a plurality of reaction mixtures are run in parallel with different agent concentrations to obtain a different response to the various concentrations.
Typically, one of these concentrations serves as a negative control, i.e., at zero concentration of agent or at a concentration of agent below the limits of assay detection.
Candidate agents encompass numerous chemical classes, although typically they are organic compounds, proteins or antibodies (and fragments thereof that bind antigen). In some preferred embodiments, the candidate agents are small organic compounds, i.e., those having a molecular weight of more than 50 yet less than about 2500, preferably less than about 1000 and, more preferably, less than about 500.

Candidate agents comprise functional
- 60 -chemical groups necessary for structural interactions with polypeptides and/or nucleic acids, and typically include at least an amine, carbonyl, hydroxyl, or carboxyl group, preferably at least two of the functional chemical groups and more preferably at least three of the functional chemical groups. The candidate agents can comprise cyclic carbon or heterocyclic structure and/or aromatic or polyaromatic structures substituted with one or more of the above-identified functional groups. Candidate agents also can be biomolecules such as peptides, saccharides, fatty acids, sterols, isoprenoids, purines, pyrimidines, derivatives or structural analogs of the above, or combinations thereof and the like.
Candidate agents are obtained from a wide variety of sources including libraries of synthetic or natural compounds. For example, numerous means are available for random and directed synthesis of a wide variety of organic compounds and biomolecules, including expression of randomized oligonucleotides, synthetic organic combinatorial libraries, phage display libraries of random or non-random peptides, combinatorial libraries of proteins or antibodies, and the like. Alternatively, libraries of natural compounds in the form of bacterial, fungal, plant, and animal extracts are available or readily produced. Additionally, natural and synthetically produced libraries and compounds can be readily be modified through conventional chemical, physical, and biochemical means. Further, known agents may be subjected to directed or random chemical modifications such as acylation, alkylation, esterification, amidification, etc. to produce structural analogs of the agents.
A variety of other reagents also can be included in the mixture. These include reagents such as salts, buffers, neutral proteins (e.g., albumin), detergents, etc. which may be used to facilitate optimal protein-protein and/or protein-agent binding. Such a reagent may also reduce non-specific or background interactions of the reaction components. Other reagents that improve the efficiency of the assay such as protease inhibitors, nuclease inhibitors, antimicrobial agents, and the like may also be used.
The mixture of the foregoing reaction materials is incubated under conditions whereby, the candidate agent interacts with the PSMA enzyme. The order of addition of components, incubation temperature, time of incubation, and other parameters of the assay may be readily determined. Such experimentation merely involves optimization of the assay parameters, not the fundamental composition of the assay. Incubation temperatures typically are between 4 C and 40 C. Incubation times preferably are minimized to facilitate rapid, high throughput screening, and typically are between 0.1 and 10 hours.

- 61 -After incubation, the presence or absence of PSMA enzyme activity is detected by any convenient method available to the user. For example, the reaction mixture can contain a substrate for the PSMA enzyme. Preferably the substrate and/or the product formed by the action of the PSMA enzyme are detectable. The substrate usually comprises, or is coupled to, a detectable label. A wide variety of labels can be used, such as those that provide direct detection (e.g., radioactivity, luminescence, optical, or electron density, etc) or indirect detection (e.g., epitope tag such as the FLAG epitope, enzyme tag such as horseradish peroxidase, etc.). The label may be bound to the substrate, or incorporated into the structure of the substrate.
A variety of methods may be used to detect the label, depending on the nature of the label and other assay components. For example, the label may be detected while bound to the substrate or subsequent to separation from the substrate. Labels may be directly detected through optical or electron density, radioactive emissions, nonradiative energy transfers, etc.
or indirectly detected with antibody conjugates, strepavidin-biotin conjugates, etc. Methods for detecting a variety of labels are well known in the art.

Example 1: Generation of a panel of monoclonal antibodies (mAbs) to conformational gitopes on PSMA
- 63 -A panel of anti-PSMA mAbs that represent promising candidates for therapy was created. Briefly, the mAbs were generated as follows: BALB/c mice were immunized subcutaneously with recombinant PSMA at approximately three-week intervals.
After a total of 4 injections, mice were sacrificed and their splenocytes fused with a m.yeloma cell line using standard techniques in order to create hybridomas. Individual hybridoma supernatants were screened by ELISA for reactivity with PSMA derived from either LNCaP
human prostate tumor cells or from 3T3 cells engineered to express full-length human PSMA (3T3-PSMA cells). Positive clones were secondarily screened by flow cytometry for specific reactivity with intact 3T3-PSMA and LNCaP cells so as to select antibodies that recognize native, cell-surface PSMA and thus have the greatest therapeutic potential.
Mice having the ability to produce human antibodies (XenoMouse, Abgenix;
Mendez et al., Nature Genetics 15:146, 1997) were immunized subcutaneously once or twice weekly with 5 X 106 LNCaP cells adjuvanted with alum or Titermax Gold (Sigma Chemical Co., St.
Louis, MO). Animals were boosted twice with 10 lug of recombinant PSMA protein immunoaffinity captured onto protein G magnetic microbeads (Miltenyi Biotec, Auburn, CA). PSMA mAb 3.11 was used for capture. Splenocytes were fused with NSO
myeloma cells and the hybridomas that resulted were screened as above by flow cytometry to detect clones producing antibodies reactive with the extracellular portion of PSMA.
One clone, 10.3 (PTA-3347), produced such antibodies.
These methods have yielded a high proportion of mAbs that react exclusively with conformation-specific epitopes on cell-surface PSMA. As shown in Fig. 1, several (mAbs 3.7, 3.9, 3.11, 5.4, and 10.3) but not all (mAb 3.12) mAbs specifically bind viable PSMA-expressing cells. Using recombinant soluble PSMA proteins expressed in Chinese hamster ovary (CHO) cell lines, it further was demonstrated that the mAbs bind epitopes in the extracellular region of PSMA. The mAbs were also tested for their ability to immunoprecipitate native PSMA from 3T3-PSMA cell lysates. The mAbs positive in flow cytometry (Fig. 1) were also effective in immunoprecipitation (Fig. 2), whereas mAb 3.12 was unreactive. Fig. 3 shows the recognition of non-denatured full-length PSMA
and recombinant soluble PSMA by several PSMA antibodies that recognize PSMA
conformation.
This further confirms that these methods yield a preponderance of mAbs that efficiently recognize native PSMA.

- 64 -The mAbs were tested for reactivity with denatured PSMA by Western blot analysis (Fig. 4). Lysates from the indicated cells and samples (controls: 3T3 cells, PSMA-negative human prostate cell lines PC-3 and DU145, mock supernatant; PSMA-positive samples:
PSMA-expressing 3T3 cells, PSMA-positive human prostate cell line LNCaP, rsPSMA-positive supernatant) were resolved by SDS-PAGE, electroblotted, and probed with anti-PSMA mAbs 3.1 and 3.12 (ATCC Patent Deposit Designations PTA-3639 and PTA-3640, respectively). Four mAbs tested in parallel (3.7, 3.8, 3.9, 3.11) showed no reactivity to either full-length or secreted rsPSMA proteins. 7E11 mAb immunoprecipitated full-length but not secreted rsPSMA.
The mAbs reactive in flow cytometry and immunoprecipitation (mAbs 3.7, 3.9, 3.11, 5.4, and 10.3) were all unreactive in Western blot analysis, indicating that the mAbs do not recognize linear epitopes. Taken together, the data strongly suggest that these 5 mAbs recognize conformation-specific epitopes located in the extracellular domain of PSMA.
Since mAbs to conformational epitopes typically possess the greatest affinity and specificity for antigen, they represent preferred candidates for therapy.
The reactivities of certain anti-PSMA antibodies are described in Table 2:

Although a number of anti-PSMA mAbs have been described over the years and evaluated for therapeutic potential (see, e.g., Liu, H. et al. Cancer Res. 57: 3629-3634, 1997; Chang, S.S. et al. Cancer Res. 59: 3192-3198, 1999; Murphy, G.P. et al. J Urology 160: 2396-2401, 1998), none inhibit the enzymatic activity of PSMA and few recognize conformational determinants on PSMA.
to Example 2: Production of anti-PSMA mAbs To accurately and quantitatively assess the therapeutic potential of these mAbs, the mAbs are produced in a quantity and quality suitable for extensive in vitro and in vivo characterization. Briefly, the mAb-secreting hybridomas are cultured in roller bottles in DMEM/F12 medium supplemented with 10% PBS that has been depleted of bovine IgG
(Life Technologies). During the production phase of the culture, cells are maintained at ¨5 x 106 cells/mL via twice-weekly exchanges of media. Collected media are clarified by filtration through a 0.22 micron filter and stored at ¨95 C prior to purification. Given an average antibody expression levels of ¨25 mg/L, approximately 3L of roller bottle supernatants are required for each antibody to allow for losses in purification.

Mouse IgG2a, mouse IgG2b and human IgG1 antibodies are loaded directly, but supernatants containing mouse IgG1 antibodies are adjusted to pH 8.5 and 1M NaCI prior to loading in order to promote binding.

- 66 -buffers and sanitized chromatography columns. Purified mAbs are tested for purity by reducing and nonreducing SDS-PAGE, for PSMA binding affinity by ELISA, and for endotoxin levels by the limulus amebocyte lysate assay. These procedures routinely yield "animal-grade" antibody at >95% purity and <0.5 endotoxin units per milligram of protein.
Example 3: Evaluation of the therapeutic potential of the unlabeled mAbs in vitro Purified mAbs are tested in a battery of assays for therapeutically relevant properties, including affinity, specificity, enzyme inhibitory activity and effector functions. The ideal product candidate binds and inhibits PSMA activity at subnanomolar concentrations and mediates potent cell-killing through Fe-related effector functions.
First, the mAbs' affinity for cell-surface and secreted forms of PSMA is measured by flow cytometry and ELISA, respectively. In the flow cytometry assay, varying amounts of mAbs are incubated with 5x105 3T3-PSMA cells in FACS buffer (PBS containing 1%
FBS
and 0.1% NaN3) for 2 hr to allow for saturation binding. Cells are washed and incubated with a phycoerythrin-coupled goat antibody to mouse IgG (ICN/Cappel) for detection of bound mAb by flow cytometry. Specific binding is calculated by subtracting the fluorescence intensity observed with parental 3T3 cells.
For ELISA, CHO cell-derived recombinant soluble PSMA protein (rsPSMA, Progenies, Tarrytown, NY) is diluted to 1 )_tg/m1 in 50 mM carbonate buffer, pH 9.4, and coated overnight at 4 C onto 96-well Immulon II microtiter plates at 100 pl/well. The plates are then blocked for 2 hr with PBS buffer containing 5% BSA. mAbs are added in a range of concentrations in ELISA buffer (PBS buffer containing 2% BSA, 1% FBS and 0.5%
Tween 20) for 2 hours at room temperature. The plates are washed, and horseradish peroxidase conjugated goat antibody to mouse IgG is added for 1 hr at room temperature.
The plates are washed again and 3,3',5,5'-tetramethylbenzidine dihydrochloride (TMB) substrate (Pierce, Rockford, IL) is added for colorimeffic readout at 450 nm using an ELISA
plate reader (Molecular Devices, Sunnyvale, CA).
Example 4: mAb cross-competition binding assay To identify whether a given group of mAbs recognize distinct or overlapping epitopes on PSMA, cross-competition binding assays are performed (Liu, H. et al. Cancer Res 57:

- 67 -3T3-PSMA cells in the presence or absence of varying concentrations of unlabeled competitor mAbs as described above. Following washing, phycoerythrin-conjugated streptavidin is added to determine the amount of bound biotinylated mAb. The percent inhibition is defined relative to that observed in the presence of an isotype-matched mAb of irrelevant specificity (0% inhibition) and to that observed using excess unlabeled test mAb (100% inhibition).
Example 5: Effects of mAbs on PSMA enzymatic activity PSMA has been shown to possess both folate hydrolase and N-acetylated a-linked acidic dipeptidase (NAALADase) enzymatic activities, which may influence the proliferation and malignancies of the tumor cell (Heston, W.D.W. Prostate: Basic and Clinical Aspects (R.K. Naz, ed.). CRC Press, New York: 219-243, 1997). Several of the mAbs described above (mAb 3.9, mAb 5.4 and mAb 7.3) and mAb J591 (ATCC #HB-12126) were tested for folate hydrolase modulating activity using previously described assays for measuring PSMA
enzymatic activity (Pinto, J.T. et al. Clinical Cancer Res 2: 1445-1451, 1996).
Briefly, folate hydrolase activity was measured as follows. Fifty tM
methotrexate di-gamma glutamate and 10 pg/m1rsPSMA (premixed with anti-PSMA or irrelevant mAb) was incubated in pH 4.5 acetate buffer in a volume of 1000 for 2 hr at 37 C.
Reactions were terminated by boiling for 5 minutes prior to separation of free, mono- and di-gamma glutamate forms of methotrexate by capillary electrophoresis on a Spectra Phoresis 1000 (Thermo Separation, San Jose, CA). The various methotrexate derivatives were quantified based on their retention times and absorbance at 300 nm.
The data show that mAb 5.4 potently blocks the enzymatic activity of purified rsPSMA protein and in lysates of C4-2 cells. C4-2 is an androgen independent derivative of the LNaCP cell line (human prostate cancer line) which expresses endogenous PSMA. More details regarding the C4-2 cell line may be found in O'Keefe D.S. et al.
Prostate 45: 149-157, 2000). Figures 7 and 8 provide the results for two production lots of rsPSMA
(rsPSMA #7 and rsPSMA #8). The results for the C4-2 cell lysates are shown in Figure 9.
The figures illustrate the effect of four antibodies (mAb 3.9, mAb 5.4, mAb 7.3 and mAb J591) on the enzymatic activity of folate hydrolase by way of the rate of cleavage of glutamate from methotrexate di-gamma glutamate (MTXG1u2) by folate hydrolase present in the two

production lots of rsPSMA and in the C4-2 cell lysates. In addition to the inhibitory effects of mAb 5.4, mAb 3.9 was also found to inhibit folate hydrolase activity.
For NAALADase activity assays, rsPSMA protein is incubated with varying amounts of anti-PSMA or control mAbs in 50mM Tris pH 7.4, 1mM CoC12 for 10 minutes at before adding 50 1 of 0.6iuM N-acetylaspartyl-[3H]glutamate. After 15 minutes, the reaction is stopped by adding 1 ml of 100mM NaPO4. Cleaved glutamate is separated from the substrate by ion exchange chromatography and detected by scintillation counting. Each measurement is performed in triplicate.
Example 6: Reactivity with normal and malignant human tissues by immunohistochemistry Anti-PSMA mAbs are tested by immunohistochemistry for reactivity with both normal and malignant human tissues using an avidin-biotin peroxidase method (Silver, D.A.
et al. Clin Cancer Res 3: 81-85,1997). Frozen or paraffin-embedded tissues can be used.
Paraffin-embedded tissue sections are deparaffinized and endogenous peroxidase activity is blocked by incubation with 1% H202 for 15 minutes. Sections are blocked in a 1:10 dilution of horse serum in 2% PBS-BSA (Sigma Chemical, St Louis, MO) for 30 minutes before overnight incubation with 21.1g/m1 anti-PSMA mAb in 2% PBS-BSA. After washing, sections are incubated with biotinylated secondary antibody, washed, and incubated with avidin:biotin peroxidase complexes (Vector Laboratories, Burlingame, CA) diluted 1:25 in PBS for 30 minutes. After washing, sections are visualized by immersion in PBS
containing 0.05% diaminobenzidine tetrachloride, 0.01% H202, and 0.5% Triton X-100.
Negative control sections are incubated with isotype-matched mAbs of irrelevant specificity. As a positive control, 7E11 (Cytogen, Princeton, NJ), a well-characterized anti-PSMA mAb, is used.
Example 7: Antibody-dependent cellular cytotoxicity (ADCC) In the ADCC assay, mAbs are serially diluted and combined with 51Cr-labeled PSMA cells or human prostate PC-3 cells that have been engineered to express human PSMA
(PC-3-PSMA cells). NK effector cells are purified from lymph nodes or spleens using anti-NK microbeads (Miltenyi Biotec). Sera, NK effector cells, and 51Cr-loaded target cells are co-incubated at effector:target cell ratios of 10:1, 20:1, and 40:1, with each condition performed in triplicate.

Example 8: Complement-mediated lysis (CML) For CML, 51Cr-loaded 3T3-PSMA or PC-3-PSMA cells serve as target cells. Serial dilutions of mAbs are co-incubated with rabbit complement and target cells for 4-5 hours at 37 C, with each condition being performed in triplicate. Supernatants are then collected and counted with a gamma counter. Specific lysis is computed as previously done with the ADCC assay data.
Example 9: Anti-proliferative effects To test anti-proliferative effects of these antibodies, anti-PSMA mAbs are serially diluted and incubated with LNCaP, PC-3-PSMA and parental PC-3 cells in log-phase growth.
At 4 hr, 24 hr, and 72 hr intervals, cells are removed and analyzed for density and viability by =
trypan blue staining and WST-1 assay (Roche Biochemicals).
Example 10: Optimization of chelation and radiolabeling procedures The most promising mAbs identified using the procedures described in the foregoing examples will be optimized for biochemical and biological stability and activity after labeling prior to evaluation in animals. Success in in vitro experiments is defined as identification of a radiolabeled mAb that specifically kills PSMA-expressing tumor cells at >10-fold lower concentrations than unlabeled or similarly labeled isotype control mAb.
Because the preferred a- and n-emitting isotopes are all radiometals, each of the mAbs is first conjugated with an appropriate metal chelating agent. Based on the favorable in vivo stability data and its proven use in human clinical trials, the bifunctional chelating agent C-functionalized trans cyclohexyldiethylenetriaminepentaacetic acid (p-SCN-CHX-A"-DTPA) is the preferred agent for attaching either 90Y or 213Bi to the antibody (Brechbiel, M.W. et al. J. Chem. Soc. Chem. Commun. 1169-1170, 1991). A form of this chelate has previously been tested in more than 70 doses in humans in ongoing trials at Memorial-Sloan Kettering Cancer Center (McDevitt, M.R. et al. J. Nucl. Med. 40:1722-1727, 1999).

The objective is to optimize the antibody conjugation and chelation ratios to maximize labeling yield and activity while maintaining suitable stability for in vivo utilization. Additional chelating agents also are used as they become available from the N.I.H. and other sources.
Initially, the antibody is rendered metal-free by incubation with a large molar excess of EDTA at pH=5. The EDTA and any metals scavenged from the antibody preparation are removed via continuous buffer exchange/dialysis so as to replace the pH=5 buffer with the conjugation buffer (Nikula, T.K. et al. Nucl. Med. Biol. 22:387-390, 1995).
Conditions that yield optimal chelator to antibody ratio but still remain immunoreactive are identified by systematically varying the chelator:antibody ratio, reaction time, temperature, and/or buffer systems about initial conditions that employ a 40-fold molar excess of chelator to antibody in HEPES buffer, pH 8.5. The number of chelates bound per antibody is determined using an established spectrophotometric method (Pippin, C.G. et al. Bioconjugate Chemistiy 3: 342-345, 1992).
For 90Y and 225AC constructs, labeling efficiency is measured directly. For 213Bi, initial antibody constructs are tested for chelation efficiency using 111m which has similar chelation chemistry as 213Bi but possesses the advantages of a longer half life (ti/2=3 days), ready availability, and traceable 7-emission. Once optimized using 1111n, labeling efficiency is determined for 213Bi.
Radiolabeled mAb is purified over a BioRad 10DG desalting column using 1% HSA
as the mobile phase and evaluated by instant thin layer liquid chromatography (ITLC) and/or high performance liquid chromatography (HPLC) to determine the percent incorporation of radionuclide (Zamora, P.O. et al. Biotechniques 16: 306-311, 1994). ITLC and HPLC
provide a means of establishing purity and identifying the percent of low molecular weight radiochemical impurities (i.e., metal chelates, colloids, and free metal).
Duplicate ITLC
strips for each mobile phase are developed, dried, and cut at the Rf of 0.5 mark and counted in a gamma counter. The HPLC system is equipped with both an online UV
absorption detector and radioactivity detector. The HPLC elution profile directly correlates radioactivity with protein and low molecular weight species as a function of the elution time. A TSK
SW3000xL column (TosoHaas, Montgomeryville, PA) is used and calibrated using a range of protein molecular weight standards.

- 71 -Example 11: Affinity and immunoreactivity of radiolabeled mAbs Once radiolabeled constructs are obtained, purified, and assessed for biochemical and radiochemical purity, biological activity is determined. Binding activity of the radioconstruct is performed by Scatchard analysis of binding data obtained using whole LNCaP
and 3T3-PSMA cells and/or membrane fractions as previously described (Scheinberg, D.A.
et al.
Leukemia 3: 440-445 (1991).
The immunoreactivity of the synthetic constructs is evaluated in order to correlate the chelate:antibody molar ratio with the biological activity. Briefly, 2 ng of labeled mAb is incubated with a ¨25-fold excess of PSMA as expressed on 3T3-PSMA cells. After a 30 min incubation at 0 C, the cells are collected by centrifugation and the supernatant containing unbound mAb is added to fresh 3T3-PSMA cells for an additional 30 min at 0 C.
Both sets of cells are centrifuged and washed twice with cold PBS. The cell pellets, supernatant and wash fractions are counted for radioactivity. Immunoreactivity is defined as the amount of radioactivity in the cell pellets divided by the total radioactivity in the cell pellets, supernatant and wash fractions.
Example 12: mAb internalization The activity of radiolabeled mAbs can be significantly modulated by their internalization rates. Internalization of the cell surface antibody-antigen complex is measured using Win radiolabeled antibody constructs (Caron, P.C. et al. Cancer Res 52:
6761-6767, 1992). Briefly, 5x105 3T3-PSMA cells are incubated at 37 C with 111In radiolabeled antibody for varying time periods. Cells are washed with PBS and cell-surface bound radiolabeled constructs are stripped with lml of 50mM glycine/150mM NaC1, pH=2.8. Total cell-associated radioactivity and acid-resistant (internalized) radioactivity are determined by y-counting to ascertain the rate of internalization. Parental 3T3 cells that do not express PSMA are used as a control to determine non-specific binding. Based upon previous results by other groups (Smith-Jones P.M. et al. Cancer Res 60: 5237-5243, 2000), significant internalization of PSMA after binding with one or more of the mAb constructs is expected.

and 3T3-PSMA cells and/or membrane fractions as previously described (Scheinberg, D.A.
et al.
Leukemia 3: 440-445 (1991).
The immunoreactivity of the synthetic constructs is evaluated in order to correlate the chelate:antibody molar ratio with the biological activity. Briefly, 2 ng of labeled mAb is incubated with a ¨25-fold excess of PSMA as expressed on 3T3-PSMA cells. After a 30 min incubation at 0 C, the cells are collected by centrifugation and the supernatant containing unbound mAb is added to fresh 3T3-PSMA cells for an additional 30 min at 0 C.
Both sets of cells are centrifuged and washed twice with cold PBS. The cell pellets, supernatant and wash fractions are counted for radioactivity. Immunoreactivity is defined as the amount of radioactivity in the cell pellets divided by the total radioactivity in the cell pellets, supernatant and wash fractions.
Example 12: mAb internalization The activity of radiolabeled mAbs can be significantly modulated by their internalization rates. Internalization of the cell surface antibody-antigen complex is measured using Win radiolabeled antibody constructs (Caron, P.C. et al. Cancer Res 52:
6761-6767, 1992). Briefly, 5x105 3T3-PSMA cells are incubated at 37 C with 111In radiolabeled antibody for varying time periods. Cells are washed with PBS and cell-surface bound radiolabeled constructs are stripped with lml of 50mM glycine/150mM NaC1, pH=2.8. Total cell-associated radioactivity and acid-resistant (internalized) radioactivity are determined by y-counting to ascertain the rate of internalization. Parental 3T3 cells that do not express PSMA are used as a control to determine non-specific binding. Based upon previous results by other groups (Smith-Jones P.M. et al.

Example 13: In vitro cytotoxicity studies
- 72 -Assessment of in vitro cytotoxicity of a-labeled inAbs was undertaken once the inununoreactivity of the radioimmunoconjugate was established. Approximately 50,000 target cells (either LNCaP or 3T3-PSMA cells) were treated in 96 well plates and analyzed 24-96 hours later. Quantification of cell death due to 225Ac-labeled constructs (or 213Bi) was accomplished by determining the uptake of3H-thymidine by surviving cells (Nikula, T.K. et al. J. NucL Med. 40: 166-176, 1999). Specificity was determined by use of control cells (PSMA-negative human prostate cell lines PC-3 and DU-145, as well as control 3T3 cells), blocking with excess unlabeled antibody, and control radioconjugates.
The cytotoxic effects of antibody conjugate concentration, specific activity, and time of exposure were then assessed. Cytotoxicity was expressed relative to that seen with 1M
HC1 (100% cell death) and media (background cell death). LD50 values were calculated by plotting cell viability as a function of the number of225Ac atoms bound on the cells (McDevitt, M.R. et al. (1998) Eur. NucL Med. 25: 1341-1351 (1998).
Multicellular spheroids of LNCaP-FGC cells had been established and were used to investigate the potential of radioimmunotherapy (RIT) to eradicate minimal disease in vitro.
These three-dimensional spheroids mimic tissue structures more accurately than monolayer cultures and thus provide a more relevant model of solid tumors (O'Connor, K.C. Pharm.
Res. 16: 486-493, 1999). LNCaP-FGC is a fast growing clone of the original LNCaP cell line, and the cells were grown using a liquid overlay technique to a size of 200-6001_tm (Ballangrud, A.M. et al. ain. Cancer Res. 5: 3171s-3176s, 1999). In larger spheroids, the inner mass of cells becomes necrotic, while the outer rim consists of proliferating tumor cells.
Antibody penetration was measured by confocal microscopy, and prior results suggested that an anti-PSMA antibody should penetrate to a depth of 40-501.un (Ballangrud, A.M. et al. 7th Conference on Radioimmunodetection and Radioimmunotherapy of Cancer, Princeton NJ, 1998). The in vitro cytotoxicity of225Ac-3.9 on LNCaP target cells is shown in Figure 23.
The percentage of viable PSMA+ LNCaP cells was plotted as a function of activity of the radioconjugate. Addition of a 100-fold excess of unlabeled antibody was used as a control for specificity.

Example 14: Evaluation of the in vivo efficacy of unlabeled and radiolabeled mAbs in mouse xenograft models of human prostate cancer
- 73 -Antibodies that are successful in the foregoing assays demonstrate significant specificity and functional properties that suggest they will be useful for therapeutic use. The most promising of these radiolabeled and "naked" mAb constructs are evaluated in the best available mouse models of prostate cancer. The studies employ an established xenograft model in which the LNCaP human prostate tumor cell line is injected into immunocompromised nude mice and allowed to form solid tumors (Ellis, W.J. et al. Clin Cancer Res 2: 1039-1048 (1996), which then are treated with both radiolabeled and unlabeled anti-PSMA mAb constructs. Follow-on studies also utilize a mouse xenograft model, CWR22, which reproduces many of the key biological features of human prostate cancer.
LNCaP tumor cell xenograft model A construct showing high affinity and high specificity is taken into the LNCaP
tumor cell xenograft in vivo model for biodistribution and pharmacokinetic analysis.
1111n-labeled anti-PSMA antibody is used for these studies due to its favorable chelation chemistry, radioactive half-life and traceable gamma emission. Timepoints are evaluated as appropriate for the half-lives of213Bi, , 225 c 177 a Lu and 90Y, which are the nuclides of therapeutic interest.
Labeled radioconstructs (1-5m) are injected i.v. into nude mice (normal and tumor bearing) and the mice are sacrificed at 5 mm, 15 min, 30 mm, 60 mm, 2 hrs, 4 hrs, 18hrs, and 24hrs post-injection. Blood and major organs are taken from animals, weighed, and the percent radioactivity injected per gram of tissue is determined (Nikula, T.K. et al.
J. Nucl. Med. 40:
166-176, 1999). Specificity is addressed by pre-injection with excess unlabeled construct.
Macroscopic tumor volume and animal survival rates is recorded throughout the experiments.
A dose-ranging study is also conducted to determine the toxicity of the constructs when administered via i.v. or i.p. injection to normal and tumor-bearing mice.
These animals are routinely examined for toxic side effects during the course of the studies by blood chemistry and physical examination. Animals are sacrificed during and at the conclusion of the study in order to collect blood and body tissues for further evaluation.
Previous data has demonstrated an approximate maximum tolerated dose of 250 Ci/mouse, so total doses are kept below that level.
Once i.v. biodistribution and toxicity is documented, radiotherapy of tumors is assessed. Groups of five mice are injected with <111g radiolabeled anti-PSMA

mAb pretreatment before 213Bi, 225Ac, 177Lu and/or 90Y-labeled anti-PSMA to block specific targeting.
Groups of tumor bearing mice are injected with unlabeled anti-PSMA mAbs (at equimolar concentrations) and several dose levels of radiolabeled anti-PSMA or a similarly labeled isotype control antibody. The effect on tumor growth is assessed over time.
Statistical differences between therapy groups is determined using an analysis of variance (ANOVA) method and animal survival is illustrated using Kaplan-Meier plots.
The efficacy of 213Bi, 225Ac, 177Lu and/or 90Y-labeled anti-PSMA constructs is correlated to the data obtained in vitro. Success in these experiments is defined as the ability to significantly (p <0.05) increase life-span and/or decrease tumor volume as compared to a radiolabeled isotype control mAb.
Furthermore, the tumor models are used to test whether predosing with unlabeled antibody prior to injection of radiolabeled antibody improves delivery of the radiolabeled antibody to the tumor. The tumor-bearing mice are injected with <1 pg radiolabeled anti-PSMA antibody with or without a prior single injection of 5-100pg of unlabeled antibody.
After several days, animals are sacrificed for evaluation of the distribution of radioactivity in the tumor, normal tissue, and blood. If predosing with unlabeled antibody improves delivery and targeting of radiolabeled antibody to the tumors, this approach is applied and optimized in toxicity and therapeutic studies.
In addition to overall survival, the role of timing of the injection after tumor transplantation (Day 1 vs 3 vs 7), the role of dosage (dose-response curves using 3-4 dose levels), the role of schedule (single vs multiple divided daily injections) and the specificity of the treatment (pre-treatment with unlabeled anti-PSMA to block targeting) is examined.
These in vivo studies are designed to address the maximum tolerated dose of radiolabeled antibody, the activity of the antibody, the optimal dosing schedule (single or multiple injections), and the effect on tumor size.

-75 -CWR22 mouse xenograft model The most promising anti-PSMA mAbs in unlabeled, toxin-labeled and/or radiolabeled form are tested in the CWR22 human prostate cancer xenograft mouse model, (Wainstein, M.A. et al. Cancer Res 54:6049-6052 (1994); Nagabhushan, M. et al. Cancer Res 56:3042-3046 (1996); Pretlow, T.G. et al. J Natl Cancer Inst 85:394-398 (1993)). This model has many features of the human condition including a dependence on androgens, a correlation between measured levels of PSA in serum and tumor size, and high-level expression of PSMA. Following androgen withdrawal, PSA levels decrease to nearly undetectable levels and tumor volume decreases. Later, the tumor regrows as an androgen-independent neoplasm, manifest initially by a rise in PSA and later, measurable tumor growth. After androgen withdrawal, tumors regrow at variable time periods.
Four to six week old nude athymic BALB/c male mice are obtained from the National Cancer Institute-Frederick Cancer Center and maintained in pressurized ventilated caging.
While immunodeficient in many respects, these mice mediate wild-type levels of ADCC and CML. The CWR22 tumor line is propagated in the animals by the injection of minced tumor tissue from an established tumor into the subcutaneous tissue of the flanks of athymic nude mice together with reconstituted basement membrane (Matrigel, Collaborative Research, Bedford, MA). To maintain serum androgen levels, the mice are administered 12.5-mg sustained-release testosterone pellets (Innovative Research of America, Sarasota, FL) subcutaneously before receiving tumors. Three to four weeks after inoculation, tumors of approximately 1.5 x 1.0 x 1.0 cm are measured. Androgens are withdrawn by surgical castration under pentobarbital anesthesia and removal of the sustained-release testosterone pellets. Tumor size is determined by caliper measurements of height, width and depth. PSA
values are performed on the serum of the mice after tail bleeding using a Tandem-R PSA
immuno-radiometric assay (Hybritech, San Diego, CA).
Groups of five mice are injected with anti-PSMA mAb or a similar isotype control mAb at dosages from 5-100 g to assess anti-tumor activity. The effect of scheduling single doses vs. multiple divided daily injections is also examined. Macroscopic tumor volume and animal survival rates are recorded throughout the experiments. Statistical differences between therapy groups are determined using an analysis of variance (ANOVA) method and animal survival are illustrated using Kaplan-Meier plots, with success defined as a difference

The cells were washed twice with PBS and resuspended with 2m1 of MPerTM
Mammalian Protein Extraction Reagent (Pierce, Rockford, IL). Following incubation for 10 min at 4 C, cell debris and insoluble aggregates were removed by centrifugation at 15,000 rpm for 30 min at 4 C. The supernatant was transferred to a cryogenic vial and stored at -80 C until further use.

Polyacrylamide Gel Electrophoresis (PAGE) and Western Blotting of the different PSMA
proteins For each individual PAGE analysis, 15111 of each cell lysate and 51.11 of the purified rsPSMA were used.
SDS-PAGE was performed using standard procedures. Samples were prepared by boiling for 5 minutes in the presence of Laemmli sample buffer (with or without the reducing agent dithiothreitol [DTT]). Samples were then applied on a 4-15% Tris-Glycine gel (BioRad, Hercules, CA). After electrophoresis for lh at 200V, the proteins were transferred onto nitrocellulose (BioRad) and analyzed by Western blotting.
The oligomeric nature of the different PSMA proteins was analyzed using Blue Native PAGE (BN-PAGE). Each sample was diluted with an equal volume of 2x BN-PAGE
sample buffer (0.1M MOPS! 0.1M Tris /40% glycerol! 0.1% Coomassie G-250) prior to loading onto the gel. BN-PAGE was performed using 4-12% BisTris gels (Invitrogen, Carlsbad, CA) and 50m_M MOPS / 50mM Tris, pH 7.7 as running buffer. Coomassie Blue was omitted from the cathode buffer to avoid interference with protein binding during the transfer of the proteins onto nitrocellulose. Following electrophoresis for 2.5hrs at 125V, the proteins were transferred onto a nitrocellulose membrane (BioRad) and analyzed by Western blotting.
Western blotting was performed as follows: Subsequent to transfer, the nitrocellulose membrane was blocked with 5% milk in PBS / 0.1% Triton X-100 / 0.02% SDS, which was also used for the subsequent wash and antibody incubation steps. PSMA proteins were detected using the anti-PSMA mAbs 3.1 or 3.9 (Progenics Pharmaceuticals) as primary antibody and HRP-labeled anti-mouse IgG as secondary antibody and lh incubation at room temperature. The membranes were colorimetrically developed using chemiluminescence (NEN Plus, Perkin Elmer Life Sciences, Boston, MA).

Results Both full-length PSMA and recombinant, soluble PSMA (rsPSMA) migrate on reducing and non-reducing SDS-PAGE with a molecular weight of ¨100 kDa (Fig.
5). The
- 78 -result for full-length PSMA is in accordance with prior observations (Israeli et al., U.S. Patent 5,538,866; Murphy et al., U.S. Patent 6,158,508; Israeli, et al., Cancer Research 54:1807, 1994; Troyer et al. Int. J. Cancer 62:552, 1995; Troyer et al., The Prostate 30:233, 1997;
Grauer et al., Cancer Research 58:4787, 1998). In each of these reports, full-length PSMA
migrated as a major band of 100-120 kDa, with a minor (typically <5% of the total PSMA
protein) 180-200 kDa band observed in a subset of reports (U.S. Patent 6,158,508; Troyer et al., 1995; Troyer et al., 1997). Troyer et al. (1995) describe the 180-200 kDa species as being a noncovalently associated PSMA dimer that can be disrupted with increasing concentrations of SDS detergent.
rsPSMA contains 94% (707 of 750) of the amino acids present in full-length PSMA, and the two proteins are not clearly resolved in this analysis, as expected.
SDS-PAGE allows the analysis of denatured proteins only. In order to examine native proteins in their native state, other techniques have to be employed, such as Blue Native PAGE (BN-PAGE). BN-PAGE is used to determine the native molecular weight of proteins and their noncovalent complexes (Schagger & v. Jagow, Anal. Biochem.
199:223-231, 1991; Schagger et al., Anal. Biochenz. 217:220-230, 1994). The dye Coomassie Blue G-250 binds to the hydrophobic domains on the surface of most proteins, enhances solubility, and introduces a charge shift on the native proteins resulting in migration towards the anode at pH 7.5 irrespective of the isoelectic point of the protein. Although the migration velocity of proteins in BN-PAGE varies somewhat, the molecular mass of proteins can be determined by their respective end points of migration due to the decreasing pore size of the acrylamide gradient present in the gels.
When analyzed by BN-PAGE, full-length PSMA (extracted from LNCaP or 3T3 cells) as well as purified rsPSMA migrate with a molecular weight of ¨190kDa (Fig. 6). This surprising observation for full-length PSMA indicates that the predominant form of cell-surface PSMA is a noncovalently associated dimer. This unexpected result can be contrasted with that of previous reports (U.S. Patent 6,158,508; Troyer et al. 1995;
Troyer et al., 1997), where the PSMA dimer represents a minor species in SDS-PAGE analyses.
Presumably, the noncovalent PSMA dimer is largely dissociated by boiling in the presence of the denaturing detergent SDS.
Moreover, the result for the purified rsPSMA protein indicates that the dimer is stabilized via interactions between extracellular amino acids in addition to or exclusive of
Grauer et al., Cancer Research 58:4787, 1998). In each of these reports, full-length PSMA
migrated as a major band of 100-120 kDa, with a minor (typically <5% of the total PSMA
protein) 180-200 kDa band observed in a subset of reports (U.S. Patent 6,158,508; Troyer et al., 1995; Troyer et al., 1997). Troyer et al. (1995) describe the 180-200 kDa species as being a noncovalently associated PSMA dimer that can be disrupted with increasing concentrations of SDS detergent.
rsPSMA contains 94% (707 of 750) of the amino acids present in full-length PSMA, and the two proteins are not clearly resolved in this analysis, as expected.
SDS-PAGE allows the analysis of denatured proteins only. In order to examine native proteins in their native state, other techniques have to be employed, such as Blue Native PAGE (BN-PAGE). BN-PAGE is used to determine the native molecular weight of proteins and their noncovalent complexes (Schagger & v. Jagow, Anal. Biochem.
199:223-231, 1991; Schagger et al., Anal. Biochenz. 217:220-230, 1994). The dye Coomassie Blue G-250 binds to the hydrophobic domains on the surface of most proteins, enhances solubility, and introduces a charge shift on the native proteins resulting in migration towards the anode at pH 7.5 irrespective of the isoelectic point of the protein. Although the migration velocity of proteins in BN-PAGE varies somewhat, the molecular mass of proteins can be determined by their respective end points of migration due to the decreasing pore size of the acrylamide gradient present in the gels.
When analyzed by BN-PAGE, full-length PSMA (extracted from LNCaP or 3T3 cells) as well as purified rsPSMA migrate with a molecular weight of ¨190kDa (Fig. 6). This surprising observation for full-length PSMA indicates that the predominant form of cell-surface PSMA is a noncovalently associated dimer. This unexpected result can be contrasted with that of previous reports (U.S. Patent 6,158,508; Troyer et al. 1995;
Troyer et al., 1997), where the PSMA dimer represents a minor species in SDS-PAGE analyses.
Presumably, the noncovalent PSMA dimer is largely dissociated by boiling in the presence of the denaturing detergent SDS.
Moreover, the result for the purified rsPSMA protein indicates that the dimer is stabilized via interactions between extracellular amino acids in addition to or exclusive of
- 79 -amino acids in the transmembrane or intracellular segments, which are not present in rsPSMA.
Example 16: Dissociation of PSMA Multimers PSMA is a putative zinc metalloprotease, and site-directed mutagenesis of amino acids implicated in zinc binding results in a profound loss of enzymatic activity (Speno et al., Molecular Pharmacology, 55:179, 1999). These amino acids include His-377, Asp-387, Glu-425, Asp-453 and His-553. Ethylenediaminetetraacetic acid (EDTA) is a strong chelating agent for Zn2+ and other divalent cations, and thus has the potential to remove Zn24-or other coordinate divalent cations from PSMA. We have determined that EDTA
treatment causes the PSMA homodimer to dissociate into monomeric subunits. Similar results can be expected for other agents that possess similar chelating properties, such as ethyleneglycol-bis(beta-aminoethyl ether) (EGTA).
The purified rsPSMA protein was incubated with or without 10mIvIEDTA for 16 hr at 4 C and then analyzed by BN-PAGE. Under these conditions, the EDTA-treated protein was monomeric, whereas rsPSMA remained dimeric in the absence of EDTA.
Although the dissociation of the PSMA dimer into monomer was essentially complete, any residual dimeric protein can be removed if desired by gel filtration, ultracentrifugation or other size-based separation methods that are well-known to those skilled in the art.
Example 17: Methods for identifying promoters of PSMA dissociation Compounds are screened for the ability to promote dissociation of PSMA dimers using a method that includes:
(a) contacting a PSMA dimer with a compound under conditions that do not promote dissociation of the PSMA dimer in the absence of the compound;
(b) measuring the amount of PSMA monomer; and (c) comparing the amount of PSMA monomer measured in the presence of the compound with that observed in the absence of the compound.
An increase in the amount of PSMA monomer measured in the presence of the compound indicates that the compound is capable of promoting dissociation of the PSMA
dimer.

antibody constructs were added into each well. After a 2 hour incubation on ice for competition binding, the cells were washed 5 times using cold PBS. The cells containing bound In-111 antibodies were recovered from microplates into test tubes and counted in a gamma counter.
Results detailed in Figures 29 show that mJ591 blocked In-111 4.40 binding to PSMA-3T3 cells and did not block In-111 4.304. In addition, 4.40 and 4.304 did not block each other.

followed by a "dissociation phase" for 10 min. SPR was monitored and displayed as a function of time.
For each antibody at one concentration, the chip was regenerated and equilibrated. An example of the analysis of antibody PRGX1-XG-006 in association phase and dissociation phase at different concentrations of rsPSMA from 100 nM to 6.25 nM is shown in Figure 31.
Thermodynamic and kinetic rate constants of binding were calculated using the Biacore Evaluation software. For example, the affinity of XG-006 antibodies in a supernatant to rsPSMA was determined to be 4.92x10-1 M with a Ka of 1.3x105 M-1 s-1 and a Kd of 6.4x10-5 s-1. Selective data for several human PSMA antibodies in crude supernatant, purified form, and modified with bifunctional chelate is listed in Table 4 for comparison.
Binding activity of In-111 radiolabeled antibodies was determined by Scatchard analysis of binding data obtained using PSMA-expressing cells (LNCaP, C4.2, and parental 3T3 as a control). The experimental procedures and methods of data analysis have been described previously (Scheinberg, D.A. et al. Leukemia 3: 440-445 (1991).

Selective data for several human PSMA antibodies in crude supernatant, purified form, and modified with bifunctional chelate is listed in Table 4 for comparison.
Binding activity of In-111 radiolabeled antibodies was determined by Scatchard analysis of binding data obtained using PSMA-expressing cells (LNCaP, C4.2, and parental 3T3 as a control). The experimental procedures and methods of data analysis have been described previously (Scheinberg, D.A. et al. Leukemia 3: 440-445 (1991).

- 88 -Example 24: Cytotoxicity of radiolabeled antibody The in vitro cytotoxicity of Ac-225 labeled anti-PSMA antibody was determined using methodology similar to that used in Example 19. Prostate cancer cells (1001.11, of C4-2, LNCaP, and PC3 cells at a concentration of 2 x 104 cells/mL) were placed into separate well of a 96 well microplate. After overnight incubation, the cells were treated with Ac-225 labeled human anti-PSMA 4.40 antibody at different concentrations for over 4 days. Cell cytotoxicity was quantified using Alamar Blue (Biosource International, Camarillo, CA).
Figure 34 shows a plot of cell survival vs. Ac-225 activity concentration. The for PSMA expressing cells (C4-2 and LNCaP) was <2 nCi/mL. However, the EC50 was 420 nCi/mL for PC3 cells, which do not express PSMA on the cell surface.
Therefore, the Ac-225 labeled human anti-PSMA 4.40 antibody shows > 200-fold selectivity in killing PSMA
expressing prostate cancer cells (C4-2 and LNCaP) vs. control cells (PC3).
Example 25: In Vivo Radioimmunotherapv with Lu-177 Labeled Antibodies Athymic nude mice from the National Cancer Institute were implanted subcutaneously with 2 x 106 PSMA-3T3 cells. After measurable tumors appeared at day 7 post implantation, the mice were treated by injection with either a single 250 uCi dose human anti-PSMA antibody 4.40 or 4.304 labeled with Lu-177 (University of Missouri Research Reactor), or were injected with buffer only as control. The tumor size of individual animals was measured using an electronic caliper. Figure 35 shows a plot of the median tumor size in each group overtime. Tumor growths were substantially reduced in Lu-177 antibody treated groups compared to the control group.
Example 26: Immunization with rsPSMA dimer preparations Immunization BALB/c mice were immunized by subcutaneous injection at days 0, 7, 14, and 42 with either 5 ps clinical rsPSMA lot # 4019-0001 (75 % dimer/25 % monomer) or 5 lig rsPSMA batch # TD045-003 run 1/peak 2 (100 % monomer) and adjuvanted with 50 lig alhydrogel per dose. Serum was drawn 10 days after the fourth immunization and analyzed by enzyme-linked immunoassay (ETA) and flow cytometry.
Figure 34 shows a plot of cell survival vs. Ac-225 activity concentration. The for PSMA expressing cells (C4-2 and LNCaP) was <2 nCi/mL. However, the EC50 was 420 nCi/mL for PC3 cells, which do not express PSMA on the cell surface.
