Description

[Technical Field]

[0001] Cross-reference of related applications This application claims priority under 35 U.S.C. § 119(e) of U.S. Provisional Application 62 / 977,932 filed February 18, 2020, and incorporates the entire disclosure thereof herein by reference.

[0002] Field of Invention The present invention relates to a method for treating prostate cancer and other cancers that express prostate-specific membrane antigen (PSMA), such as PSMA-expressing cancers and cancers that express PSMA in neovascular structures. In particular, the present invention provides a novel therapy based on a combination of a PSMA therapeutic agent, such as radiolabeled compound I disclosed herein, and an immuno-oncology (IO) therapeutic agent, wherein the IO therapeutic agent is selected from LAG-3 inhibitors, TIM-3 inhibitors, GITR agonists, TGF-β inhibitors, IL15 / IL-15RA complexes, PD-1 inhibitors, PD-L1 inhibitors, and CTLA-4 inhibitors. [Background technology]

[0003] Background and Overview of the Invention The prostate gland is a male reproductive organ that functions to produce and store semen, which provides nutrients and fluids for the survival of sperm introduced into the vagina during reproduction. Like other tissues, the prostate can develop malignant (cancerous) or benign (non-cancerous) tumors. In fact, prostate cancer is one of the most common cancers in men in Western society and the second most common form of malignant tumor in American men. Current treatments for prostate cancer include hormone therapy, radiation therapy, surgery, chemotherapy, photodynamic therapy, and combination therapy. However, many of these treatments affect the quality of life of patients, especially men diagnosed with prostate cancer after the age of 50. For example, the use of hormone therapy is often accompanied by side effects such as osteoporosis and liver damage. Such side effects are more selective or specific to the tissue responsible for the diseased condition and should be mitigated by using treatments that avoid non-target tissues such as bone or liver.

[0004] Prostate-specific membrane antigen (PSMA) is a biomarker expressed in prostate cancer. PSMA can be overexpressed in malignant prostate tissue compared to other organs in the human body, such as the kidneys, proximal small intestine, and salivary glands. PSMA is also expressed in neovascular structures within many non-prostate solid tumors, including lung, colon, breast, kidney, liver, and pancreatic carcinomas, but not in normal vascular structures. PSMA expression in the brain is also minimal. PSMA is a type II cell surface membrane-bound glycoprotein with a molecular weight of approximately 110 kD, containing an intracellular segment (amino acids 1-18), a transmembrane domain (amino acids 19-43), and a broad extracellular domain (amino acids 44-750). While the functions of the intracellular segment and transmembrane domain are currently considered trivial, the extracellular domain is involved in several different activities. For example, PSMA plays a role in the central nervous system, where it metabolizes N-acetyl-aspartylglutamate (NAAG) to glutamine and N-acetylaspartate. PSMA also plays a role in the proximal small intestine, removing gamma-linked glutamate from poly-gamma-glutamate folate and alpha-linked glutamate from peptides and small molecules. However, the specific function of PSMA in prostate cancer cells remains unclear.

[0005] PSMA is named primarily because of its high expression levels in prostate cancer cells compared to other tissues; however, its specific function in prostate cancer cells remains unclear. PSMA expression is highly restricted in normal tissues. It is present only in salivary gland tissue, kidney tissue, and a small number of cells in the small and large intestines. PSMA is overexpressed in malignant prostate tissue compared to other organs in the human body, such as the kidneys, proximal small intestine, and salivary glands. Higher PSMA expression is associated with higher malignancy, metastasis, and castration resistance. Tumor expression of PSMA in prostate cancer is typically 100 to 1,000 times higher than in normal tissue. Unlike many other membrane-bound proteins, PSMA undergoes rapid intracellular translocation in a manner similar to cell surface-bound receptors such as vitamin receptors. PSMA translocates via clathrin-coated pits and can then be recycled to the cell surface or go to lysosomes. Therefore, diagnostic agents, contrast agents, and therapeutic agents can target PSMA for delivery to PSMA-expressing cells, such as prostate cancer cells.

[0006] PSMA is also expressed in neovascularization in cancers other than prostate cancer, such as thyroid cancer, renal clear cell carcinoma, bladder transitional cell carcinoma, colon adenocarcinoma, neuroendocrine cancer, glioblastoma multiforme, malignant melanoma, pancreatic ductal carcinoma, non-small cell lung cancer, soft tissue sarcoma, and breast cancer. These cancers represent a broad range of cancers with different histological subtypes, growth rates, and cell cycle times. In some cases, the cancer is embedded within normal tissue, which can alter radioresistance. Furthermore, hypoxic areas of large deposits also become radioresistant. These and other factors are known to result in various intrinsic responses to traditional external beam radiotherapy. [Overview of the project]

[0007] While the activity of PSMA on the cell surface of prostate cells is under investigation, PSMA has been shown to be a viable target for the selective and / or specific delivery of bioactive agents, including drug compounds, or combinations of bioactive agents, to such prostate cells. Some such drug compounds are formulated with formula I [ka] It is a compound or a salt thereof.

[0008] Compound I can be described as a small molecule that specifically binds to PSMA (prostate-specific membrane antigen) expressed on the surface of prostate cancer cells. Compound I is a pharmacophore ligand, glutamate-urea-lysine; chelator, DOTA( 177 Lu and 225 It can be characterized as consisting of a compound that can complex with Ac and a linker that connects the ligand and the chelator. Although not bound by theory, it is thought that urea-based pharmacophore ligands can bind drugs to PSMA at the disease site and allow for internal delivery. Furthermore, it is thought that binding of I-Lu or I-Ac can lead to internal delivery via endocytosis, which can provide sustained retention of the ligand and its bound radioactive cargo within cancer cells. When used here, the term "compound I" is used in the context of therapy, and it binds to a radionuclide.

[0009] The radioactive ligand therapy (RLT) used in the clinic is for thyroid cancer. 131 I and for bone metastasis treatment 223 Radium or 89 It contains alpha-emitting elements such as strontium.

[0010] 177 Lu has a half-life of 6.7 days. It travels undisorderly through tissues, moving approximately 20–80 cells or 0.5–2 mm, emitting 0.5 MeV energy consisting of negatively charged beta particles (electrons) that primarily cause base damage and single-strand disruption. At high doses, these lesions can interact to convert sublethal damage (SLD) or potentially lethal damage (PLD) into irreversible lethal damage. 177 Lu also emits 113kv and 208kV radiation, which can be used for contrast imaging.

[0011] 225The half-life of Ac is 9.9 days, and it emits 8.38 MeV energy alpha particles during imaging. Only a mere 0.5% of the energy is emitted as 142 Kv photons. Therefore, most of the radiation particles are positively charged and are approximately 8,000 times larger than beta particles. Furthermore, the energy from these particles deposits over a relatively short distance (2 - 3 cells). As a result, there is high-density and severe tissue damage in the form of double-strand breaks with multiple damage sites representing irreparable lethal damage. This is referred to as high linear energy transfer (LET) or densely ionizing ionization and delivers 3 - 7 times more absorbed dose than beta particles. The type of cell damage caused by any isotope ( 177 Lu or 225 Ac) is predicted to be different due to the differences in the characteristics of each projectile. 177 Lu provides radiation with a long path length and can thus effectively deliver radiation to adjacent cells. In particular, the predominance of single-strand breaks, especially in the presence of oxygen, provides an opportunity to repair sublethal damage (SLD) and / or potentially lethal damage (PLD), which are optimal conditions for normal tissue repair. Conversely, 225 Ac delivers extremely powerful, high LET radiation and has a much more limited potential to repair normal tissue. The radiobiological effectiveness of alpha radiation is at least 5 times that of beta irradiation, and the biological effect ratio (RBE) should be considered for the irradiation dose. 225 Ac treatment is more effective even in hypoxic tumor regions because the type of DNA damage caused does not require oxygen. 225 A potential drawback of Ac treatment is that due to the short path length, a large amount of damaging radiation may deposit only within a short distance of 2 - 4 cells.

[0012] Combinations of therapeutic agents based on combinations of PSMA therapeutic agents and cancer immunotherapy (I-O) therapeutic agents and methods of treating PSMA-expressing cancers are described herein.

[0013] Cancer immunotherapy (I-O) therapeutic agents can break established resistance to cancer and restore an effective cancer-specific immune response.

[0014] The internal radiation of tumor cells provided by the radiolabeled compounds I described herein, particularly compound Ia, can damage tumors, induce the release of tumor antigens, and thus allow the immune system to better visualize the tumor. IO therapy provides immune checkpoint blockade and therefore improves the immune anti-tumor T cell response. In this way, IO therapy can synergistically enhance the effects of internal radiation by radiolabeled compounds I, particularly compound Ia.

[0015] The present invention provides a novel combination of a PSMA therapeutic agent, for example, compound I, particularly compound Ia, and one or more cancer immunotherapy (IO) therapeutic agents for use in treating PSMA-expressing cancers in a subject, wherein the IO therapeutic agent is selected from the group consisting of LAG-3 inhibitors, TIM-3 inhibitors, GITR agonists, TGF-β inhibitors, IL15 / IL-15RA complexes, PD-1 inhibitors, PD-L1 inhibitors, and CTLA-4 inhibitors.

In one embodiment, in combination therapy, the concentration of the second therapeutic agent required to achieve inhibition, e.g., growth inhibition, is lower than the therapeutic dose of the second therapeutic agent as monotherapy, e.g., 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower. In one embodiment, in combination therapy, the concentration of the first therapeutic agent required to achieve inhibition, e.g., proliferation inhibition, is lower than the therapeutic dose of the first therapeutic agent as monotherapy, e.g., at least 10-20%, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, or 80-90% lower.

[0075] The terms “inhibition,” “inhibitor,” or “antagonist” include a reduction in a parameter of a molecule, such as an immune checkpoint inhibitor, e.g., activity. For example, inhibition of activity by at least or about 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or more of the activity of a molecule, e.g., an inhibitory molecule, is included in this term. Therefore, inhibition does not have to be 100%.

[0076] A "fusion protein" and a "fusion polypeptide" are proteins or polypeptides having at least two parts covalently linked to each other, where each part is a polypeptide having different properties. These properties can be biological, such as in vitro or in vivo activity. They can also be simple chemical or physical properties, such as binding to a target molecule or catalysis of a reaction. The two parts may be linked directly by a single peptide bond or via a peptide linker, but are within a leading frame relative to each other.

[0077] The terms “activation,” “activator,” or “agonist” involve an increase in a parameter of a molecule, such as a co-stimulatory molecule, e.g., activity. For example, an increase of at least or about 5%, 10%, 15%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or more of activity, e.g., co-stimulatory activity, is included in this term.

[0078] The term "anti-cancer effect" refers to biological effects that can be manifested by various means, including, but not limited to, a reduction in tumor volume, a reduction in the number of cancer cells, a reduction in the number of metastases, an extension of life expectancy, a reduction in cancer cell proliferation, a reduction in cancer cell survival, or an improvement in various physiological symptoms associated with the cancerous state. "Anti-cancer effect" can also be manifested by the ability of the therapeutic agents described herein (e.g., peptides, polynucleotides, cells, small molecules, and antibodies) to first prevent the development of cancer.

[0079] The term "antitumor effect" refers to a biological effect that can be manifested by various means, including, but not limited to, a reduction in tumor volume, a reduction in tumor cell number, a reduction in tumor cell proliferation, or a reduction in tumor cell survival.

[0080] The term "cancer" refers to a disease characterized by the rapid and immature proliferation of abnormal cells, but may include benign cancers. In various embodiments, cancer cells may spread locally or to other parts of the body via the bloodstream and lymphatic system. In some embodiments, cancer is PSMA-expressing cancer; in other embodiments, PSMA may be expressed in the neovascularization of cancer. Examples of various cancers are described herein and include, but are not limited to, breast cancer, prostate cancer, ovarian cancer, cervical cancer, skin cancer, pancreatic cancer, colorectal cancer, kidney cancer, liver cancer, brain cancer, lymphoma, leukemia, lung cancer, thyroid cancer, renal clear cell carcinoma, bladder transitional cell carcinoma, colon adenocarcinoma, neuroendocrine cancer, glioblastoma multiforme, malignant melanoma, pancreatic ductal carcinoma, non-small cell lung cancer, soft tissue sarcoma, etc. In some embodiments, cancer is selected from the group consisting of glioma, carcinoma, sarcoma, lymphoma, melanoma, mesothelioma, nasopharyngeal carcinoma, leukemia, adenocarcinoma, and myeloma. Other exemplary cancers include small cell lung cancer, bone cancer, head and neck cancer, hepatocellular carcinoma, cutaneous or intraocular melanoma, uterine cancer, gastric cancer, colon cancer, fallopian tube cancer, endometrial cancer, cervical cancer, vaginal cancer, vulvar cancer, Hodgkin's disease, gastric and esophageal cancer, endocrine cancer, parathyroid cancer, adrenal cancer, urethral cancer, penile cancer, ureteral cancer, central nervous system (CNS) tumors, primary CNS lymphoma, spinal axis tumors, brainstem gliomas, pituitary adenomas, inflammatory myofibroblastic tumors, and combinations thereof.

[0081] The terms “tumor” and “cancer” are used interchangeably here, and both terms encompass tumors of solid and liquid nature, for example, generalized or circulating. When used here, the terms “cancer” or “tumor” include premalignant, as well as malignant cancers and tumors and benign cancers. When used here, the term “cancer” includes primary malignant cells or tumors (for example, cells that have not migrated to a location other than the original malignant tumor or tumor site in the subject body) and secondary malignant cells or tumors (for example, those resulting from metastasis, which is the migration of malignant cells or tumor cells to a secondary site different from the original tumor site).

[0082] As used herein, the terms “treatment” and “to treat” mean a reduction or improvement in the progression, severity and / or duration of a disorder, such as cancer, a proliferative disorder, or improvement in one or more symptoms of the disorder (e.g., one or more recognizable symptoms), resulting from the administration of one or more treatments or therapeutic agents. In specific embodiments, the terms “treatment” and “to treat” mean an improvement in at least one measurable physical parameter of a proliferative disorder, such as cancer, which is not necessarily recognizable by the patient, such as tumor growth. In other embodiments, the terms “treatment” and “to treat” mean inhibition of the progression of a proliferative disorder, such as cancer, by physical means, for example, by stabilization of recognizable symptoms, or by physiological means, for example, by stabilization of physical parameters, or both. In other embodiments, the terms “treatment” and “to treat” mean a reduction or stabilization of tumor size or cancer cell count.

[0083] In many of the embodiments described herein, the therapeutic agent administered as described herein in combination with a PSMA therapeutic agent such as radiolabeled compound I, particularly compound Ia, may be an antibody or other polypeptide or a nucleic acid encoding such polypeptide. In some embodiments, the therapeutic agent described herein for use in combination with a PSMA therapeutic agent such as radiolabeled compound I, particularly compound Ia, comprises a polypeptide and / or nucleic acid having the sequence specified herein or a sequence substantially identical or similar thereto, for example, a sequence that is at least 85%, 90%, 95%, 96%, 97%, 98%, or 99% identical to the sequence specified herein. In amino acid sequences, the term “substantially identical” as used herein means a first amino acid sequence containing a sufficient or minimum number of amino acid residues that are i) identical to or ii) conserved substitutions of aligned amino acid residues in the second amino acid sequence, such that the first and second amino acid sequences may have a common structural domain and / or common functional activity. For example, a control sequence, such as an amino acid sequence containing a common structural domain that is at least about 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% identical to the sequence provided herein, is substantially similar to the amino acid sequence provided herein.

[0084] In nucleotide sequences, the term "substantially identical" as used herein means a first nucleic acid sequence containing a sufficient or minimum number of nucleotides that are identical to the aligned nucleotides in the second nucleic acid sequence such that the first and second nucleotide sequences encode a polypeptide having common functional activity or a common structural polypeptide domain or common functional polypeptide activity. For example, a control sequence, e.g., a nucleotide sequence having at least about 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% identity with the sequence provided herein, is substantially identical to the nucleic acid sequence provided herein.

[0085] The term "functional variant" refers to a polypeptide that has a naturally occurring sequence or a substantially identical amino acid sequence to the sequence provided herein, is encoded by substantially identical nucleotide sequences, and can have one or more activities of the naturally occurring sequence or the sequence provided herein.

[0086] In various embodiments, the calculation of homology, sequence identity, or similarity between sequences (these terms are used interchangeably here) can be carried out as follows:

[0087] To determine the percentage identity of two amino acid sequences or two nucleic acid sequences, the sequences may be aligned for optimal comparison purposes (for example, gaps may be introduced in one or both of the first and second amino acid or nucleic acid sequences for optimal alignment, and non-homologous sequences may be ignored for comparison purposes). In various embodiments, the length of the reference sequence aligned for comparison purposes is at least 30%, at least 40%, at least 50%, or 60%, or at least 70%, 80%, 90%, or 100% of the length of the reference sequence. Then, amino acid residues or nucleotides at the corresponding amino acid or nucleotide positions may be compared. If a position in the first sequence is occupied by the same amino acid residue or nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position (wherein used, amino acid or nucleic acid "identity" is equivalent to amino acid or nucleic acid "homology").

[0088] Percent identity between two arrays is a function of the number of identical positions shared by the arrays, taking into account, for example, the number of gaps and the length of each gap, which was necessary to introduce for optimal alignment of the two arrays.

[0089] In one embodiment, the comparison of sequences and determination of percentage identity between two sequences can be achieved using a mathematical algorithm. In one embodiment, the percentage identity between two amino acid sequences is determined using the Needleman and Wunsch ((1970) J. Mol. Biol. 48:444-453) algorithm, which is incorporated into the GAP program of the GCG software package (available at www.gcg.com), using a Blossum 62 matrix or PAM250 matrix and gap weights 16, 14, 12, 10, 8, 6 or 4 and length weights 1, 2, 3, 4, 5 or 6. In yet another embodiment, the percentage identity between two nucleotide sequences is determined using the GAP program of the GCG software package (available at www.gcg.com), using an NWSgapdna.CMP matrix and gap weights 40, 50, 60, 70 or 80 and length weights 1, 2, 3, 4, 5 or 6. In one embodiment, the set of parameters that can be used is a Blossum 62 scoring matrix with a gap penalty of 12, a gap extension penalty of 4, and a frameshift gap penalty of 5.

[0090] In one explanatory embodiment, the percentage identity between two amino acid or nucleotide sequences can be determined using the algorithm of E. Meyers and W. Miller ((1989) CABIOS, 4:11-17), which is incorporated into the ALIGN program (version 2.0), using the PAM120 weighted residue table, gap length penalty 12, and gap penalty 4.

[0091] In one embodiment, the nucleic acid and amino acid sequences described herein can be used as "query sequences" to perform a search against public databases, for example, to identify other family members or related sequences. Such searches can be performed using the NBLAST and XBLAST programs (version 2.0) described in Altschul, et al. (1990) J. Mol. Biol. 215:403-10. In one embodiment, a BLAST nucleotide search can be performed in the NBLAST program with a score of 100 and a word length of 12 to obtain nucleotide sequences homologous to the nucleic acid molecules described herein. In one embodiment, a BLAST amino acid sequence search can be performed in the XBLAST program with a score of 50 and a word length of 3 to obtain amino acid sequences homologous to the amino acid sequences described herein. In one explanatory embodiment, to obtain gapped alignments for comparative purposes, Gapped BLAST can be used as described in Altschul et al., (1997) Nucleic Acids Res. 25:3389-3402. In other embodiments, when using the BLAST and Gapped BLAST programs, the fault parameters of each program (e.g., XBLAST and NBLAST) may be used. See www.ncbi.nlm.nih.gov.

[0092] As used herein, the terms "hybridize under low stringency, medium stringency, high stringency, or very high stringency conditions" describe the conditions for hybridization and washing. Exemplary guidance for carrying out hybridization reactions can be found in the current protocol in Molecular Biology, John Wiley & Sons, NY (1989), 6.3.1–6.3.6, which is incorporated herein by reference. Aqueous and non-aqueous methods are described in that reference, and either may be used. The exemplary specific hybridization conditions described herein are as follows: 1) Low-stringency hybridization conditions involve washing twice with 6× sodium chloride / sodium citrate (SSC) at approximately 45°C, followed by 0.2× SSC and 0.1% SDS at at least 50°C (the washing temperature may be increased up to 55°C for low-stringency conditions); 2) Medium-stringency hybridization conditions involve washing once or twice with 6× SSC at approximately 45°C, followed by 0.2× SSC and 0.1% SDS at 60°C; 3) High-stringency hybridization conditions involve washing once or once with 6× SSC at approximately 45°C, followed by 0.2× SSC and 0.1% SDS at 65°C; and 4) Ultra-high-stringency hybridization conditions involve washing once or once with 0.5M sodium phosphate and 7% SDS at 65°C, followed by 0.2× SSC and 1% SDS at 65°C. In some embodiments, therapeutic agents for use in the combinations and methods described herein may have further conservative or non-essential amino acid substitutions that do not substantially affect the function of the therapeutic agents described herein.

[0093] The term "amino acid" is intended to encompass all molecules, whether natural or synthetic, that contain both amino and acid functional groups and can be included in polymers of naturally occurring amino acids. Examples of amino acids include naturally occurring amino acids; their analogs, derivatives, and congeners; amino acid analogs with variant side chains; and all stereoisomers of any of the foregoing. As used herein, the term "amino acid" includes both D- and L-optical isomers and peptide mimetic compounds.

[0094] A "conservative amino acid substitution" is the replacement of an amino acid residue with an amino acid residue having a similar side chain. Families of amino acid residues with similar side chains are defined in this art. These families include amino acids having basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), non-charged side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine), nonpolar side chains (e.g., alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, tryptophan), beta-branched side chains (e.g., threonine, valine, isoleucine), and aromatic side chains (e.g., tyrosine, phenylalanine, tryptophan, histidine).

[0095] The terms “polypeptide,” “peptide,” and “protein” (if single-chain) are used interchangeably here to refer to amino acid polymers of any length. The polymers may be linear or branched, may contain modified amino acids, and may have non-amino acid molecules in between. The term also encompasses amino acid polymers modified by any other operation, such as disulfide bond formation, glucosylation, lipid addition, acetylation, phosphorylation, or conjugation with labeling components. In various embodiments, polypeptides may be isolated from natural sources, produced by recombinant techniques from eukaryotic or prokaryotic hosts, or be products of synthetic methods.

[0096] The terms “nucleic acid,” “nucleic acid sequence,” “nucleotide sequence,” or “polynucleotide sequence” and “polynucleotide” are interchangeable. These refer to polymeric forms of nucleotides of any length, such as deoxyribonucleotides or ribonucleotides or their analogues. In some embodiments, polynucleotides may be single-stranded or double-stranded, and if single-stranded, they may be coding or non-coding (antisense) strands. In various embodiments, polynucleotides may include modified nucleotides such as methylated nucleotides and nucleotide analogs, and nucleotide sequences may be further modified after polymerization, such as by the presence of non-nucleotide components and / or by conjugation with labeling components. In various embodiments, nucleic acids may be recombinant polynucleotides or polynucleotides of genomic, cDNA, semi-synthetic or synthetic origin, which are linked with other polynucleotides in non-natural or non-natural configurations.

[0097] The term "isolated," as used herein, refers to a substance removed from its original or natural environment (e.g., the natural environment, if it exists naturally). For example, a naturally occurring polynucleotide or polypeptide present in a living animal is not isolated, but the same polynucleotide or polypeptide separated from some or all of the substances simultaneously present in the natural system by human intervention is isolated. Such a polynucleotide is part of a vector and / or such a polynucleotide or polypeptide is part of a composition, and such a vector or composition is still isolated if it is not part of the environment in which it is found naturally.

[0098] Various aspects of the present invention are described in further detail below. Further definitions are given throughout the specification.

[0099] antibody molecule In one embodiment, the combination described herein comprises a therapeutic agent which is an antibody molecule together with a PSMA therapeutic agent such as radiolabeled compound I, particularly compound Ia, or the method described herein involves using such a therapeutic agent which is an antibody molecule together with a PSMA therapeutic agent such as radiolabeled compound I, particularly compound Ia.

[0100] As used herein, the term “antibody molecule” refers to a protein containing at least one immunoglobulin variable domain sequence. The term “antibody molecule” includes, for example, full-length, mature antibodies and antigen-binding fragments of antibodies. For example, an antibody molecule may contain a heavy (H) chain variable domain sequence (hereinafter abbreviated as VH) and a light (L) chain variable domain sequence (hereinafter abbreviated as VL). In other examples, an antibody molecule may contain two heavy (H) chain variable domain sequences and two light (L) chain variable domain sequences, thereby forming two antigen-binding sites such as Fab, Fab', F(ab')2, Fc, Fd, Fd', Fv, single-chain antibodies (e.g., scFv), single-variable domain antibodies, bispecific antibodies (Dab) (bivalent and bispecific), and chimeric (e.g., humanized) antibodies, which can be produced by modification of the entire antibody or de novo-synthesized using recombinant DNA technology. In some embodiments, a functional antibody fragment retains the ability to selectively bind to each antigen or receptor. In various embodiments, antibodies and antibody fragments may be derived from any class and any subclass of antibodies (e.g., IgG1, IgG2, IgG3, and IgG4), including but not limited to IgG, IgA, IgM, IgD, and IgE, and may be monoclonal or polyclonal, human, humanized, CDR-transplanted, or in vitro-produced antibodies. In other embodiments, the antibody may have a heavy chain constant region selected from, for example, IgG1, IgG2, IgG3, or IgG4. In other embodiments, the antibody may have a light chain selected from, for example, kappa or lambda.

[0101] Examples of antigen-binding fragments include (i) Fab fragments, which are monovalent fragments consisting of VL, VH, CL, and CH1 domains; (ii) F(ab')2 fragments, which are bivalent fragments containing two Fab fragments linked by disulfide crosslinking at the hinge region; (iii) Fd fragments, which consist of VH and CH1 domains; (iv) Fv fragments, which consist of VL and VH domains of a single arm of an antibody; (v) bispecific antibody (dAb) fragments, which consist of a VH domain; (vi) camelid or camelid variable domains; (vii) single-stranded 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); and (viii) single-domain antibodies. In one embodiment, these antibody fragments can be obtained using conventional techniques known to those skilled in the art, and the fragments can be screened for usefulness in the same manner as intact antibodies.

[0102] The term "antibody" includes intact molecules and their functional fragments. In various embodiments, the constant region of an antibody may be modified, for example, mutated, to alter the properties of the antibody (e.g., for Fc receptor binding, antibody glucosylation, cysteine ​​residue count, or an increase or decrease of one or more effector cell functions or complement functions).

[0103] In one embodiment, the antibody molecule may also be a single-domain antibody. A single-domain antibody may include an antibody in which the complementarity-determining region is part of a single-domain polypeptide. Examples include, but are not limited to, heavy-chain antibodies, naturally occurring light-chain-deficient antibodies, single-domain antibodies derived from conventional four-chain antibodies, engineered antibodies, and non-antibody-derived single-domain scaffolds. A single-domain antibody may be any single-domain antibody known in the art or any future single-domain antibody. In various embodiments, a single-domain antibody may be derived from any species, including, but not limited to, mouse, human, camel, llama, fish, shark, goat, rabbit, and cattle. According to another aspect of the invention, a single-domain antibody is a naturally occurring single-domain antibody known as a light-chain-deficient heavy-chain antibody. Such a single-domain antibody is disclosed, for example, in WO9404678. For clarity, this variable domain derived from a naturally occurring light-chain-deficient heavy-chain antibody is referred here to as VHH or nanobody to distinguish it from the conventional VH of four-chain immunoglobulins. Such VHH molecules may originate from antibodies produced in camelid species, such as camels, llamas, dromedaries, alpacas, and guanacos. Other non-camellid species may naturally produce heavy-chain antibodies lacking light chains; such VHHs are within the scope of this invention.

[0104] The VH and VL regions can be subdivided into highly variable regions called "complementarity determination regions" (CDRs), which contain scattered, more conserved regions called "framework regions" (FR or FW).

[0105] The scope of the framework region and CDR is strictly defined by several methods (see Kabat, EA, et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, US Department of Health and Human Services, NIH Publication No. 91-3242; Chothia, C. et al. (1987) J. Mol. Biol. 196:901-917; and the AbM definition used in Oxford Molecular's AbM antibody modeling software. Generally, see, for example, Protein Sequence and Structure Analysis of Antibody Variable Domains. In: Antibody Engineering Lab Manual (Ed.: Duebel, S. and Kontermann, R., Springer-Verlag, Heidelberg).

[0106] In this context, the terms "complementarity-determining region" and "CDR" refer to the amino acid sequences within the antibody variable region that confer antigen specificity and binding affinity. Generally, each heavy chain variable region has three CDRs (HCDR1, HCDR2, HCDR3) and each light chain variable region has three CDRs (LCDR1, LCDR2, LCDR3).

[0107] The precise amino acid sequence boundaries of a given CDR can be determined using one of several well-known schemes, including those described by Kabat et al. (1991), “Sequences of Proteins of Immunological Interest,” 5th Ed. Public Health Service, National Institutes of Health, Bethesda, MD (“Kabat” numbering scheme) and Al-Lazikani et al., (1997) JMB 273,927-948 (“Chothia” numbering scheme). When used here, CDRs defined by the “Chothia” numbering scheme are sometimes referred to as “hypervariable loops.”

[0108] For example, under Kabat, the CDR amino acid residues of the heavy chain variable domain (VH) are numbered 31-35 (HCDR1), 50-65 (HCDR2), and 95-102 (HCDR3); and the CDR amino acid residues of the light chain variable domain (VL) are numbered 24-34 (LCDR1), 50-56 (LCDR2), and 89-97 (LCDR3). Under Chothia, the CDR amino acids of VH are numbered 26-32 (HCDR1), 52-56 (HCDR2), and 95-102 (HCDR3); and the amino acid residues of VL are numbered 26-32 (LCDR1), 50-52 (LCDR2), and 91-96 (LCDR3). By combining the CDR definitions of both Kabat and Chothia, the CDR consists of amino acid residues 26-35 (HCDR1), 50-65 (HCDR2), and 95-102 (HCDR3) in human VH, and amino acid residues 24-34 (LCDR1), 50-56 (LCDR2), and 89-97 (LCDR3) in human VL.

[0109] As used herein, "immunoglobulin variable domain sequence" refers to an amino acid sequence capable of forming the structure of an immunoglobulin variable domain. For example, a sequence may include all or part of the amino acid sequence of a naturally occurring variable domain. For example, a sequence may or may not include one, two, or more N-terminal or C-terminal amino acids, and may include other modifications that are compatible with the formation of a protein structure.

[0110] The term "antigen-binding site" refers to a portion of an antibody molecule that contains determinants that form an interface for binding to an antigen or its epitope. For proteins (or protein mimes), the antigen-binding site typically includes one or more loops (of at least four amino acids or amino acid mimes) that form an interface for binding to the antigen. Typically, the antigen-binding site of an antibody molecule includes at least one or two CDRs and / or hypervariable loops, or more typically, at least three, four, five, or six CDRs and / or hypervariable loops.

[0111] As used herein, the terms "monoclonal antibody" or "monoclonal antibody composition" refer to a preparation of an antibody molecule with a single-molecule composition. Monoclonal antibody compositions exhibit single-binding specificity and affinity for a particular epitope. Monoclonal antibodies can be manufactured by hybridoma technology or by non-hybridoma technology methods (e.g., recombinant methods).

[0112] An "effectively human" protein is one that does not elicit a neutralizing antibody response, such as a human anti-mouse antibody (HAMA) response. HAMA can be problematic in some situations, for example, if antibody molecules are repeatedly administered in the treatment of chronic or recurrent disease conditions. The HAMA response may render repeated antibody administration ineffective due to increased antibody clearance from serum (see, e.g., Saleh et al., Cancer Immunol. Immunother., 32:180-190 (1990)) and also due to the possibility of an allergic reaction (see, e.g., LoBuglio et al., Hybridoma, 5:5117-5123 (1986)).

[0113] In various embodiments, the antibody molecule may be a polyclonal or monoclonal antibody. In other embodiments, the antibody may be produced by recombinant methods, for example, by phage display or combinatorial methods.

[0114] Phage display and combinatorial methods for antibody production are known in the art (for example, all of which are incorporated herein by reference: Ladner et al. U.S. Patent 5,223,409; Kang et al. International Publication WO92 / 18619; Dower et al. International Publication WO91 / 17271; Winter et al. International Publication WO92 / 20791; Markland et al.

(1991) PNAS (As described in 88:7978-7982).

[0115] In one embodiment, the antibody is either a fully human antibody (e.g., an antibody produced in a mouse genetically engineered to produce antibodies from human immunoglobulin sequences) or a non-human antibody, such as a rodent (mouse or rat), goat, primate (e.g., monkey), or camel antibody. In one embodiment, the non-human antibody is a rodent (mouse or rat antibody). Methods for producing rodent antibodies are known in the art.

[0116] Human monoclonal antibodies can be produced using transgenic mice that carry human immunoglobulin genes, rather than using mouse strains. Splenocytes from these transgenic mice immunized with the target antigen can be used to produce hybridomas that secrete human mAbs with specific affinity for epitopes from human proteins (e.g., Wood et al. International Application WO91 / 00906, Kucherlapati et al. PCT Publication WO91 / 10741; Lonberg et al. International Application WO92 / 03918; Kay et al. International Application 92 / 03917; Lonberg, N. et al. 1994 Nature 368:856-859; Green, LL et al. 1994 Nature Genet. 7:13-21; Morrison, SL et al. 1994 Proc. Natl. Acad. Sci. USA 81:6851-6855; Bruggeman et al. 1993 Year Immunol 7:33-40; Tuaillon et al. 1993 PNAS 90:3720-3724; Bruggeman et al. 1991 Eur J Immunol 21:1323-1326).

[0117] In one embodiment, the antibody may have a variable region or part thereof, e.g., a CDR, produced in a non-human organism, e.g., a rat or mouse. In another embodiment, chimeric, CDR-implanted, and humanized antibodies may be used. In yet another embodiment, an antibody produced in a non-human organism, e.g., a rat or mouse, and then modified, e.g., by modifying the variable framework or constant region to reduce its antigenicity in humans may be used.

[0118] Chimeric antibodies can be produced using recombinant DNA technology known in this field (Robinson et al., International Patent Publication PCT / US86 / 02269; Akira, et al., European Patent Application 184,187; Taniguchi, M., European Patent Application 171,496; Morrison et al., European Patent Application 173,494; Neuberger et al., International Application WO86 / 01533; Cabilly et al., US Patent 4,816,567; Cabilly et al., European Patent Application 125,023; Better et al. (1988 Science 240:1041-1043); Liu et al. (1987) PNAS 84:3439-3443; Liu et al., 1987, J. Immunol. 139:3521-3526; Sun et al.). (See PNAS 84:214-218 (1987); Nishimura et al., 1987, Canc. Res. 47:999-1005; Wood et al. (1985) Nature 314:446-449; and Shaw et al., 1988, J. Natl Cancer Inst. 80:1553-1559).

[0119] In one embodiment, a humanized or CDR-transplanted antibody may have at least one or two, but generally three, recipient CDRs (heavy and / or light immunoglobulin chains) replaced by donor CDRs. In various embodiments, the antibody may be replaced by at least a portion of non-human CDRs, or only a portion of the CDRs may be replaced by non-human CDRs. In one explanatory embodiment, the number of CDRs required for the humanized antibody to bind to the antigen may be replaced. In one embodiment, the donor may be a rodent antibody, e.g., a rat or mouse antibody, and the recipient may be a human framework or a human consensus framework. Typically, the immunoglobulin providing the CDRs is referred to as the “donor,” and the immunoglobulin providing the framework is referred to as the “acceptor.” In one embodiment, the donor immunoglobulin is non-human (e.g., rodent). In one exemplary embodiment, the acceptor framework is a naturally occurring (e.g., human) framework or consensus framework or an array of similarities, with approximately 85% or more, or approximately 90%, 95%, 96%, 97%, 98%, or 99% or more.

[0120] In this context, the term "consensus sequence" refers to a sequence formed from the most frequently occurring amino acids (or nucleotides) within a family of related sequences (see, for example, Winnaker, From Genes to Clones (Verlagsgesellschaft, Weinheim, Germany 1987)). Within a family of proteins, each position in the consensus sequence is occupied by the most frequently occurring amino acid at that position within the family. If two amino acids occur with equal frequency, either may be included in the consensus sequence. "Consensus framework" refers to the framework region within a consensus immunoglobulin sequence.

[0121] Antibodies can be humanized by methods known in this field (see, for example, Morrison, SL, 1985, Science 229:1202-1207, by Oi et al., 1986, BioTechniques 4:214 and Queen et al. US5,585,089, US5,693,761 and US5,693,762, all of which are incorporated herein by reference).

[0122] Humanized or CDR-implanted antibodies can be produced by CDR implantation or CDR substitution, in which one, two, or all CDRs in the immunoglobulin chain can be replaced. See, for example, U.S. Patent 5,225,539; Jones et al. 1986 Nature 321:552-525; Verhoeyan et al. 1988 Science 239:1534; Beidler et al. 1988 J. Immunol. 141:4053-4060; Winter US5,225,539, all of which are expressly incorporated herein by reference. Winter describes a CDR implantation method that can be used to prepare humanized antibodies used in the combinations and methods described herein (UK Patent Application GB2188638A, filed March 26, 1987; Winter US5,225,539), all of which are expressly incorporated herein by reference.

[0123] Further, humanized antibodies in which specific amino acids are substituted, deleted, or added may be used. Criteria for selecting amino acids from a donor are described in columns 12-16 of US5,585,089, for example, the content of which is incorporated herein by reference. Other techniques for humanizing antibodies are described in Padlan et al. EP519596A1, published December 23, 1992.

[0124] In one embodiment, the antibody molecule may be a single-chain antibody. In one embodiment, a single-chain antibody (scFV) may be manipulated (see, for example, Colcher, D. et al. (1999) Ann NY Acad Sci 880:263-80; and Reiter, Y. (1996) Clin Cancer Res 2:245-52). In another embodiment, a single-chain antibody may be dimerized or polymerized to produce a polyvalent antibody that is specific to various epitopes of the same target protein.

[0125] In yet another embodiment, the antibody molecule has a heavy chain constant region, for example, IgG1, IgG2, IgG3, IgG4, IgM, IgA1, IgA2, IgD, and IgE; or a heavy chain constant region selected from, for example, the (e.g., human) heavy chain constant regions of IgG1, IgG2, IgG3, and IgG4. In another embodiment, the antibody molecule has a light chain constant region, selected from, for example, the (e.g., human) light chain constant regions of kappa or lambda. In another embodiment, the constant region may be modified, for example, mutated, to modify the properties of the antibody (e.g., Fc receptor binding, antibody glucosylation, cysteine ​​residue count, one or more increases or decreases in effector cell function and / or complement function). In one embodiment, the antibody has effector function and can immobilize complement. In another embodiment, the antibody does not recruit effector cells or immobilize complement. In another embodiment, the antibody has reduced or no ability to bind to the Fc receptor. For example, isotypes or subtypes, fragments or other variants that do not support binding to the Fc receptor, such as those in which the Fc receptor binding region is mutagenic or deleted.

[0126] Methods for modifying the constant region of an antibody are known in the art. In one embodiment, an antibody with modified function, such as modified affinity for an effector ligand like cellular FcR or the C1 component of complement, can be produced by replacing at least one amino acid residue in the constant region of the antibody with a different residue (see, for example, EP388,151A1, U.S. Patent 5,624,821 and U.S. Patent 5,648,260, all of which are incorporated herein by reference). Similar types of modifications can be used to reduce or eliminate these functions when applied to immunoglobulins of mouse or other species.

[0127] In one embodiment, an antibody molecule may be derivatized with or linked to another functional molecule (e.g., another peptide or protein). As used herein, the “derivativeized” antibody molecule is modified. Methods of derivatization include, but are not limited to, the addition of affinity ligands such as fluorescent moieties, radionucleotides, toxins, enzymes, or biotin. Therefore, antibody molecules used as therapeutic agents in conjunction with PSMA therapeutic agents such as the radiolabeled compound I described herein may include derivatized and other modified forms of the antibodies described herein, including immunoadhesion molecules. For example, an antibody molecule may be functionally linked (chemically coupled, genetically fused, non-covalently associated, or otherwise) to one or more other molecules, such as other antibodies (e.g., bispecific antibodies), detectable agents, cytotoxic agents, drugs, and / or proteins or peptides (e.g., streptavidin core regions or polyhistidine tags) that can mediate the association of an antibody or antibody moiety with other molecules.

[0128] In one embodiment, a certain type of derivatized antibody molecule is produced by crosslinking two or more antibodies (of the same type or different types to, for example, create a bispecific antibody). Suitable crosslinkers include heterobifunctional or homobifunctional (e.g., disuccinimidyl suberate) having two distinctly reactive groups separated by a suitable spacer (e.g., m-maleimidobenzoyl-N-hydroxysuccinimidyl). Such linkers are available from Pierce Chemical Company, Rockford, Ill.

[0129] In various embodiments, antibody molecules may be conjugated with other molecules, typically labeling or therapeutic agents (e.g., cytotoxic or cell proliferation inhibitors) or moieties. Radioisotopes may be used in therapeutic applications. Radioisotopes that can bind to antibodies include, but are not limited to, α-, β-, or γ-emitters or β- and γ-emitters. Such radioisotopes include iodine ( 131 I or 125 I), Yttrium ( 90 Y), Lutetium ( 177 Lu), Actinium ( 225 Ac), praseodymium, astatine ( 211 At), Rhenium ( 186 Re), bismuth ( 212 Bi or 213 Bi), Indium ( 111 In), technetium ( 99 mTc), phosphorus ( 32 P), Rhodium ( 188 Rh), sulfur (35S), carbon ( 14 C), tritium ( 3 H), chromium ( 51 Cr), chlorine ( 36 Cl), cobalt ( 57 Co or 58 Co), iron ( 59 Fe), selenium ( 75 Se) or gallium ( 67 This includes, but is not limited to, Ga. Radioactive isotopes useful as therapeutic agents include yttrium ( 90 Y), Lutetium (177 Lu), Actinium ( 225 Ac), praseodymium, astatine ( 211 At), Rhenium ( 186 Re), bismuth ( 212 Bi or 213 Bi) and rhodium ( 188 It contains Rh. For example, radioactive isotopes useful as labels for diagnostic use include iodine ( 131 I or 125 I), Indium ( 111 In), technetium ( 99 mTc), phosphorus ( 32 P), carbon ( 14 C) and tritium ( 3 H) or one or more of the therapeutic isotopes listed above.

[0130] In one embodiment, a radiolabeled antibody molecule and a method for labeling the same are provided. In one embodiment, a method for labeling an antibody molecule is disclosed. The method comprises contacting an antibody molecule with a chelating agent to produce a conjugated antibody. The conjugated antibody is radiolabeled with radioisotopes, for example, 111 indium, 90 yttrium, and 177 lutetium, to produce a labeled antibody molecule.

[0131] In one embodiment, as described above, antibody molecules can be conjugated into therapeutic agents. Therapeutically active radioisotopes have already been described. Examples of other therapeutic agents include Taxol, cytochalasin B, gramicidin D, ethidium bromide, emetine, mitomycin, etoposide, tenoposide, vincristine, vinblastine, colchicine, doxorubicin, daunorubicin, dihydroxyanthracinedione, mitoxantrone, mitramycin, actinomycin D, 1-dehydrotestosterone, glucocorticoids, procaine, tetracaine, lidocaine, propranolol, puromycin, meitansinoids, e.g., meitansinol (see U.S. Patent 5,208,020), CC-1065 (see U.S. Patents 5,475,092, 5,585,499, 5,846,545) and their analogues or homologues. Therapeutic agents include, but are not limited to, antimetabolites (e.g., methotrexate, 6-mercaptopurine, 6-thioguanine, cytarabine, 5-fluorouracil decarbazine), alkylating agents (e.g., mechloretamine, thiotepa chlorambucil, CC-1065, melphalan, carmustine (BSNU) and lomustine (CCNU), cyclophosphamide, busulfan, dibromomannitol, streptozocin, mitomycin C and cis-dichlorodiamine platinum(II) (DDP) cisplatin), anthracyclines (e.g., daunorubicin (formerly daunomycin) and doxorubicin), antibiotics (e.g., dactinomycin (formerly actinomycin), bleomycin, mitramycin and anthramycin (AMC)), and mitotic inhibitors (e.g., vincristine, vinblastine, taxol and maytansinoids).

[0132] multispecific antibody molecules In some embodiments, the antibody molecule used with the PSMA therapeutic agent described herein, particularly compound Ia, is a multispecific antibody molecule, for example, comprising multiple immunoglobulin variable domain sequences, where the multiple first immunoglobulin variable domain sequences have binding specificity to a first epitope, and the multiple second immunoglobulin variable domain sequences have binding specificity to a second epitope. In some embodiments, the first and second epitopes are on the same antigen, e.g., the same protein (or a subunit of a multimeric protein). In some embodiments, the first and second epitopes overlap. In some embodiments, the first and second epitopes do not overlap. In some embodiments, the first and second epitopes are on different antigens, e.g., different proteins (or different subunits of a multimeric protein). In some embodiments, the multispecific antibody molecule comprises a third, fourth, or fifth immunoglobulin variable domain. In some embodiments, the multispecific antibody molecule is a two-specific antibody molecule, a three-specific antibody molecule, or a four-specific antibody molecule.

[0133] In one embodiment, the multispecific antibody molecule is a bispecific antibody molecule. The bispecific antibody has specificity for no more than two antigens. The bispecific antibody molecule is characterized by a first immunoglobulin variable domain sequence having binding specificity to a first epitope and a second immunoglobulin variable domain sequence having binding specificity to a second epitope. In one embodiment, the bispecific antibody molecule includes a heavy chain variable domain sequence and a light chain variable domain sequence having binding specificity to a first epitope, and a heavy chain variable domain sequence and a light chain variable domain sequence having binding specificity to a second epitope. In one embodiment, the bispecific antibody molecule includes a semi-antibody having binding specificity to a first epitope and a semi-antibody having binding specificity to a second epitope. In one embodiment, the bispecific antibody molecule includes a semi-antibody or a fragment thereof having binding specificity to a first epitope and a semi-antibody or a fragment thereof having binding specificity to a second epitope. In one embodiment, the bispecific antibody molecule includes an scFv or a fragment thereof having binding specificity to a first epitope and an scFv or a fragment thereof having binding specificity to a second epitope.

[0134] Protocols for producing bispecific or heterodimeric antibody molecules are known in the art; e.g., the “knob-in-hole” approach described in US5731168; e.g., electrostatic steering Fc pair formation described in WO09 / 089004, WO06 / 106905 and WO2010 / 129304; e.g., chain exchange operation domain (SEED) heterodimer formation described in WO07 / 110205; e.g., Fab arm exchange described in WO08 / 119353, WO2011 / 131746 and WO2013 / 060867 For example, a bi-antibody conjugate, e.g., by antibody crosslinking, to produce a bi-specific structure using heterobifunctionality having an amine-reactive group and a sulfhydryl-reactive group, as described in US4433059; for example, a bi-specific antibody determinant produced by the recombination of hemiantibodies (heavy-light chain pairs or Fabs) from different antibodies via a cycle of reduction and oxidation of disulfide bonds between two heavy chains, as described in US4444878; for example, a trifunctional antibody, e.g., three Fabs crosslinked via sulfhydryl-reactive groups, as described in US5273743 Fragments; for example, pairs of scFv crosslinked via a C-terminal tail through a disulfide or amine-reactive chemical crosslink, such as the biosynthetic binding protein described in US5534254; for example, bifunctional antibodies described in US5582996, such as Fab fragments with different binding specificities, dimerized via leucine zippers (e.g., c-fos and c-jun) with a replaced constant domain; for example, bispecific and oligospecific monovalent and oligovalent receptors described in US5591828, such as one antibody VH-CH1 regions of two antibodies (two Fab fragments) linked via a polypeptide spacer between the CH1 region and the VH region of the other antibody, which typically has a light chain; for example, the bispecific DNA-antibody conjugate described in US5635602, e.g., crosslinking of an antibody or Fab fragment via a DNA double-strand fragment; for example, the bispecific fusion protein described in US5637481, e.g., an expression construct comprising two scFvs and a hydrophilic helical peptide linker and a complete constant region between them; for example, the one described in US5837242,Polyvalent and multispecific binding proteins, for example, dimers of polypeptides having a first domain with a binding region for the Ig heavy chain variable region and a second domain with a binding region for the Ig light chain variable region, generally referred to as bispecific antibodies (which form bispecific, trispecific, or tetraspecific molecules; higher-order structures are also disclosed); for example, as described in US5837821, which can dimerize to form bispecific / polyvalent molecules. Mini-body constructs having linked VL and VH chains further connected to a peptide spacer to the antibody hinge region and CH3 region; VH and VL domains linked in either direction by a short peptide linker (e.g., 5 or 10 amino acids) or without any linker, capable of dimerizing to form bispecific bispecific antibodies; trimers and tetramers, e.g., as described in US5844094; strings of VH domains (or VL domains in family members) linked by peptide bonds with a crosslinkable group at the C-terminus further linked to a VL domain, e.g., as described in US5864019; and single-chain linked polypeptides, e.g., as described in US5869620, in which both VH and VL domains linked via a peptide linker are combined into a multivalent structure via non-covalent or chemical crosslinking, and both scFV or bispecific antibody type forms are used to form, e.g., homodivalent, heterodivalent, trivalent and tetravalent structures.

The contents of the above-cited applications are incorporated herein by reference as a whole.

[0136] Cancer immunotherapy drugs Selected PD-1 inhibitors In various embodiments, IO agents may be used in conjunction with PSMA therapeutic agents such as the radiolabeled compound I described herein, particularly compound Ia. Any of the IO agents described below in this section titled "Cancer Immunotherapy Agents" may be used for cancer treatment in conjunction with PSMA therapeutic agents such as the radiolabeled compound I described herein, particularly compound Ia. For example, PD-1 inhibitors may be used. Programmed death 1 (PD-1) protein is an inhibitory member of the CD28 / CTLA-4 family of T cell regulators (Okazaki et al. (2002) Curr Opin Immunol 14: 391779-82; Bennett et al. (2003) J. Immunol. 170:711-8). Two ligands for PD-1, PD-L1 (B7-H1) and PD-L2 (B7-DC), have been identified and shown to downregulate T cell activation by binding to PD-1 (Freeman et al. (2000) J. Exp. Med. 192:1027-34; Carter et al. (2002) Eur. J. Immunol. 32:634-43). PD-L1 is abundant in a variety of human cancers (Dong et al. (2002) Nat. Med. 8:787-9).

[0137] PD-1 is known as an immunosuppressive protein that downregulates TCR signaling (Ishida, Y. et al. (1992) EMBO J. 11:3887-3895; Blank, C. et al. (Epub 2006 Dec. 29) Immunol. Immunother. 56(5):739-745). The interaction between PD-1 and PD-L1 can act as an immune checkpoint, potentially leading to, for example, tumor-infiltrating lymphopenia, decreased T-cell receptor-mediated proliferation, and / or immune evasion by cancer cells (Dong et al. (2003) J. Mol. Med. 81:281-7; Blank et al. (2005) Cancer Immunol. Immunother. 54:307-314; Konishi et al. (2004) Clin. Cancer Res. 10:5094-100). Immunosuppression can be reversed by inhibiting the local interaction between PD-1 and PD-L1 or PD-L2; when the interaction between PD-1 and PD-L2 is similarly blocked, the effect is additive (Iwai et al. (2002) Proc. Nat'l. Acad. Sci. USA 99:12293-7; Brown et al. (2003) J. Immunol. 170:1257-66).

[0138] In one embodiment, the combination or method described herein includes an IO therapeutic agent such as a PD-1 inhibitor. In one embodiment, the IO treatment agent is selected from PDR001 (Novartis), pembrolizumab (Merck & Co), pidilizumab (CureTech), durvalumab, atezolizumab, avelumab, nivolumab (Bristol-Myers Squibb Company), MK-3475, MPDL3280A, MEDI5736, ipilimumab (Bristol-Myers Squibb Company), tremelimumab, MEDI0680 (Medimmune), REGN2810 (Regeneron), TSR-042 (Tesaro), PF-06801591 (Pfizer), BGB-A317 (Beigene), BGB-108 (Beigene), INCSHR1210 (Incyte), or AMP-224 (Amplimmune). In one embodiment, the IO treatment agent is a PD-1 inhibitor, and the PD-1 inhibitor is PDR001, also known as spartalizumab. In another embodiment, the PD-1 inhibitor is not pembrolizumab.

In one embodiment, the PD-1 inhibitor is an anti-PD-1 antibody molecule such as that described in US2015 / 0210769, published July 30, 2015, entitled “Antibody Molecules to PD-1 and Uses Thereof,” which is incorporated herein by reference in its entirety.

[0195] TIM-3 inhibitor In one embodiment, the combination or method described herein includes a TIM-3 inhibitor. While not intended to be theoretically bound, TIM-3 is thought to correlate with tumor bone marrow signature in The Cancer Genome Atlas (TCGA) database, and the most abundant TIM-3 in normal peripheral blood mononuclear cells (PBMCs) is found in bone marrow cells. TIM-3 is expressed in multiple bone marrow subsets in human PBMCs, including but not limited to monocytes, macrophages, and dendritic cells.

[0196] Tumor purity estimation is performed on several TCGA tumor samples (e.g., adrenocortical carcinoma (ACC), urothelial carcinoma of the bladder (BLCA), invasive breast carcinoma (BRCA), cervical squamous cell carcinoma and cervical adenocarcinoma (CESC), colon adenocarcinoma (COAD), glioblastoma multiforme (GBM), head and neck squamous cell carcinoma (HNSC), renal chromophobe cell carcinoma (KICH), renal clear cell carcinoma (KIRC), renal papillary cell carcinoma (KIRP), and low-grade brain glioma). TIM-3 expression correlates well with (LGG), hepatocellular carcinoma of the liver (LIHC), adenocarcinoma of the lung (LUAD), squamous cell carcinoma of the lung (LUSC), serous cystadenocarcinoma of the ovary (OV), adenocarcinoma of the prostate (PRAD), adenocarcinoma of the rectum (READ), cutaneous melanoma (SKCM), thyroid cancer (THCA), endometrial carcinoma of the uterus (UCEC), and carcinosarcoma of the uterus (UCS), suggesting that TIM-3 expression in tumor samples originates from tumor invasion.

[0197] In one embodiment, the combination or method is used to treat kidney cancer (e.g., clear cell carcinoma of the kidney (KIRC) or papillary cell carcinoma of the kidney (KIRP)). In another embodiment, the combination is used to treat brain tumors (e.g., low-grade glioma of the brain (LGG) or glioblastoma multiforme (GBM)).

In some embodiments, inhibition of PD-L1 and TIM-3 may result in tumor reduction and survival in mouse models of cancer. In some embodiments, inhibition of PD-L1 and LAG-3 may result in tumor reduction and survival in mouse models of cancer.

[0203] In one embodiment, the method or combination is used to treat cancers having high levels of expression of TIM-3 and one or more bone marrow signature genes (e.g., one or more genes expressed in macrophages). In one embodiment, cancers with high levels of TIM-3 and bone marrow signature gene expression are selected from sarcoma (SARC), mesothelioma (MESO), brain tumors (e.g., glioblastoma (GBM)), kidney cancer (e.g., renal papillary cell carcinoma (KIRP)), or prostate cancer. In another embodiment, the combination or method is used to treat cancers having high levels of expression of TIM-3 and one or more T cell signature genes (e.g., one or more genes expressed in dendritic cells and / or T cells). In one embodiment, cancers with high levels of TIM-3 and T cell signature gene expression are selected from kidney cancer (e.g., renal clear cell carcinoma (KIRC)), lung cancer (e.g., lung adenocarcinoma (LUAD)), pancreatic adenocarcinoma (PAAD), prostate cancer, or testicular cancer (e.g., testicular germ cell tumor (TGCT)).

[0204] While not intended to be theoretically bound, in some embodiments, cancers that can be effectively treated by combinations or methods targeting two, three, or more of the targets described herein through clustering of signs by immunosignature can be identified, for example, by determining a patient fraction of more than 75 percent for both or all of the targets.

[0225] GITR agonist Glucocorticoid-induced TNFR-related protein (GITR) is a member of the tumor necrosis factor superfamily (TNFRSF). GITR expression is constitutively detected in mouse and human CD4+CD25+ regulatory T cells and can be further increased upon activation. In contrast, effector CD4+CD25− T cells and CD8+CD25− T cells have low to undetectable levels of GITR expression and are rapidly upregulated after T cell receptor activation. GITR expression is also detected in activated NK cells, dendritic cells and macrophages. The signaling pathways downstream of GITR have been shown to be involved in the MAPK and canonical NFκB pathways. Various TRAF family members are involved as signaling intermediates downstream of GITR (Nocentini et al. (2005) Eur. J. Immunol. 35:1016-1022).

[0226] GITR-mediated cell activation is thought to perform several functions, including, but is not limited to, co-stimulation to enhance proliferation and effector function, inhibition of regulatory T cell suppression, and protection from activation-induced cell death, depending on cell type and microenvironment (Shevach and Stephens (2006) Nat. Rev. Immunol. 6:613-618). Agonist monoclonal antibodies against mouse GITR effectively induce tumor-specific immunity and eradicate established tumors in a mouse syngeneic tumor model (Ko et al.

[0253] [Table 8]

[0254] TGF-β inhibitors In one embodiment, the combination or method described herein includes a transforming growth factor beta (also known as TGF-β, TGFβ, TGFb, or TGF-beta, and used herein interchangeably) inhibitor for use in combination with any of the IO agents described herein, similar to the above combination or method, in a PSMA therapeutic agent such as radiolabeled compound I described herein.

[0255] TGF-β belongs to a large family of structurally related cytokines, including, for example, bone morphogenetic proteins (BMPs), growth and differentiation factors, activins, and inhibins. In one embodiment, the TGF-β inhibitors described herein can bind to and / or inhibit one or more isoforms of TGF-β (e.g., one, two, or all of TGF-β1, TGF-β2, or TGF-β3).

[0256] Under normal conditions, TGF-β maintains homeostasis and restricts the proliferation of epithelial, endothelial, neuronal, and hematopoietic cell lineages, for example, by inducing antiproliferative and apoptotic responses. Canonical and non-canonical signaling pathways are involved in the cellular response to TGF-β. Activation of the TGF-β / Smad canonical pathway can mediate the antiproliferative effect of TGF-β. Non-canonical TGF-β pathways can activate further intracellular pathways, such as mitogen-active protein kinase (MAPK), phosphatidylinositol 3 kinase / protein kinase B, and Rho-like GTPases (Tian et al. Cell Signal. 2011; 23(6):951-62; Blobe et al. N Engl J Med. 2000; 342(18):1350-8), and thus regulate epithelial-mesenchymal transition (EMT) and / or cell motility.

[0257] Modifications of the TGF-β signaling pathway are associated with human diseases, such as cancer, cardiovascular disease, fibrosis, reproductive disorders, and wound healing. While not intended to be theoretically bound, in some embodiments, the role of TGF-β in cancer is thought to depend on the disease context (e.g., tumor stage and genetic alterations) and / or cellular context. For example, in the later stages of cancer, TGF-β can modulate cancer-related processes, for instance, by promoting tumor growth (e.g., EMT induction), blocking antitumor immune responses, increasing tumor-associated fibrosis, or enhancing angiogenesis (Wakefield and Hill Nat Rev Cancer. 2013; 13(5):328-41). In some embodiments, combinations or methods comprising the TGF-β inhibitors described herein are used to treat cancer in the later stages, metastatic, or advanced stages.

[0258] Preclinical evidence indicates that TGF-β plays a crucial role in immune regulation (Wojtowicz-Praga Invest New Drugs. 2003; 21(1):21-32; Yang et al. Trends Immunol. 2010; 31(6):220-7). TGF-β can downregulate the host immune response through several mechanisms, e.g., a shift in the T helper balance towards the Th2 immunophenotype; inhibition of antitumor Th1 type responses and M1 macrophages; suppression of cytotoxic CD8+ T lymphocyte (CTL), NK lymphocyte, and dendritic cell function, and production of CD4+CD25+ T regulatory cells; or enhancement of the protumor activity of M2 macrophages mediated by the secretion of immunosuppressive cytokines (e.g., IL10 or VEGF), pro-inflammatory cytokines (e.g., IL6, TNFα, or IL1), and the production of genotoxic reactive oxygen species (ROS) (Yang et al. Trends Immunol. 2010; 31(6):220-7; Truty and Urrutia Pancreatology. 2007; 7(5-6):423-35; Achyut et al Gastroenterology. 2011; 141(4):1167-78).

[0259] In one embodiment, the TGF-β inhibitor is used in combination with a PSMA therapeutic agent such as radiolabeled compound I and further with one or more (e.g., two, three, four, or all) of PD-1 inhibitors and LAG-3 inhibitors, GITR agonists, c-MET inhibitors, IDO inhibitors, or A2aR antagonists. In one embodiment, the combination or method is used to treat pancreatic cancer, colorectal cancer, gastric cancer, prostate cancer, or melanoma (e.g., refractory melanoma). In one embodiment, the TGF-β inhibitor is selected from fresolimmab or XOMA089.

[0260] Exemplary TGF-β inhibitors In one embodiment, the TGF-β inhibitor includes compounds disclosed in XOMA089 or in International Patent Application Publication WO2012 / 167143, which are incorporated herein by reference in their entirety.

[0261] XOMA089 is also known as XPA.42.089. XOMA089 is a fully human monoclonal antibody that specifically binds to and neutralizes TGF-beta 1 and 2 ligands.

[0262] The heavy chain variable region of XOMA089 has the amino acid sequence QVQLVQSGAEVKKPGSSVKVSCKASGGTFSSYAISWVRQAPGQGLEWMGGIIPIFGTANYAQKFQGRVTITADESTSTAYMELSSLRSEDTAVYYCARGLWEVRALPSVYWGQGTLVTVSS (SEQ ID NO: 240) (disclosed as SEQ ID NO: 6 in WO2012 / 167143). The light chain variable region of XOMA089 has the amino acid sequence SYELTQPPSVSVAPGQTARITCGANDIGSKSVHWYQQKAGQAPVLVVSEDIIRPSGIPERISGSNSGNTATLTISRVEAGDEADYYCQVWDRDSDQYVFGTGTKVTVLG (SEQ ID NO: 241) (disclosed as SEQ ID NO: 8 in WO2012 / 167143).

[0263] XOMA089 binds to human TGF-β isoforms with high affinity. Generally, XOMA089 binds to TGF-β1 and TGF-β2 with high affinity and to TGF-β3 with less affinity. In the Biacore assay, the K of XOMA089 to human TGF-β D The concentrations are 14.6 pM to TGF-β1, 67.3 pM to TGF-β2, and 948 pM to TGF-β3. Considering the high affinity binding to all three TGF-β isoforms, in one embodiment, XOMA089 is expected to bind to TGF-β1, 2, and 3 at the doses of XOMA089 described herein. XOMA089 cross-reacts with rodent and cynomolgus monkey TGF-β and exhibits functional activity in vitro and in vivo, making rodents and cynomolgus monkeys suitable species for toxicity testing.

[0264] While not intended to be theoretically bound, in one embodiment, resistance to PD-1 immunotherapy is thought to be associated with the presence of transcriptional signatures, including genes linking TGF-β signaling and TGF-β-dependent processes, such as wound healing or angiogenesis (Hugo et al. Cell. 2016; 165(1):35-44). In one embodiment, TGF-β blockade expands the therapeutic range of therapies that inhibit the PD-1 / PD-L1 axis. TGF-β inhibitors may influence the clinical benefits of PD-1 immunotherapy, for example, by modulating factors affecting the tumor microenvironment, such as vascularization, fibrosis, or effector T cell recruitment (Yang et al. Trends Immunol. 2010; 31(6):220-7; Wakefield and Hill Nat Rev Cancer. 2013; 13(5):328-41; Truty and Urrutia Pancreatology. 2007; 7(5-6):423-35).

[0265] While not intended to be constrained by theory, in certain embodiments, it is conceivable that some elements of the antitumor immune cycle expressing PD-1 and TGF-β receptors, or both, may propagate non-redundant cellular signaling. For example, in a mouse model of autotopic prostate cancer, the use of either dominant-negative morphology of TGFBRII or suppression of TGF-β production in T cells delayed tumor growth (Donkor et al. Immunity. 2011; 35(1):123-34; Diener et al. Lab Invest. 2009; 89(2):142-51). Studies in transgenic adenocarcinoma (TRAMP) mice of the mouse prostate showed that blocking TGF-β signaling in adoptive T cells increased persistence and antitumor activity (Chou et al. J Immunol. 2012; 189(8):3936-46). The antitumor activity of transplanted T cells may decrease over time, partly due to upregulation of PD-1 in tumor-infiltrating lymphocytes, supporting the PD-1 and TGF-β inhibitory combinations described herein. The use of neutralizing antibodies against PD-1 or TGF-β may also affect Tregs, considering the high expression levels of PD-1 and the response to TGF-β stimulation (Riella et al. Am J Transplant. 2012; 12(10):2575-87), supporting the PD-1 and TGF-β inhibitory combinations for treating cancer, for example, by enhancing the regulation of Treg differentiation and function.

[0266] While not intended to be constrained by theory, it is conceivable that cancer can use TGF-β to evade immune surveillance to promote tumor growth and metastatic progression. For example, in some advanced cancers, high levels of TGF-β are associated with tumor aggressiveness and poor prognosis, and the TGF-β pathway can promote one or more of cancer cell motility, aggression, EMT, or stem cell phenotypes. Immune regulation mediated by cancer cells and leukocyte populations (e.g., via diverse cell expression or secretion molecules, e.g., IL-10 or TGF-β) may limit the response to checkpoint inhibitors as monotherapy in some patients. In one embodiment, combined inhibition of TGF-β and checkpoint inhibitors (e.g., PD-1 inhibitors described herein) is used to treat cancers that do not respond or respond poorly to checkpoint inhibitor (e.g., anti-PD-1) monotherapy, such as pancreatic cancer or colorectal cancer (e.g., microsatellite-stable colorectal cancer (MSS-CRC)). In other embodiments, combined inhibition of TGF-β and checkpoint inhibitors (e.g., PD-1 inhibitors described herein) is used to treat cancers exhibiting high levels of effector T cell infiltration, such as lung cancer (e.g., non-small cell lung cancer), breast cancer (e.g., triple-negative breast cancer), liver cancer (e.g., hepatocellular carcinoma), prostate cancer, or kidney cancer (e.g., clear cell renal cell carcinoma). In some embodiments, combinations of TGF-β inhibitors and PD-1 inhibitors may produce synergistic effects.

[0267] In one embodiment, the TGF-β inhibitor (e.g., XOMA089) is administered in doses of 0.1 mg / kg to 20 mg / kg, for example, 0.1 mg / kg to 15 mg / kg, 0.1 mg / kg to 12 mg / kg, 0.3 mg / kg to 6 mg / kg, 1 mg / kg to 3 mg / kg, 0.1 mg / kg to 1 mg / kg, 0.1 mg / kg to 0.5 mg / kg, 0.1 mg / kg to 0.3 mg / kg, and 0.3 mg / kg. The dosage is g / kg to 3 mg / kg, 0.3 mg / kg to 1 mg / kg, 3 mg / kg to 6 mg / kg, or 6 mg / kg to 12 mg / kg, for example, approximately 0.1 mg / kg, 0.3 mg / kg, 0.5 mg / kg, 1 mg / kg, 3 mg / kg, 6 mg / kg, 12 mg / kg, or 15 mg / kg, for example, administered once a week, once every two weeks, once every three weeks, once every four weeks, or once every six weeks.

For example, the TGF-β inhibitor (e.g., XOMA089) may be administered in doses of 0.1 mg / kg to 1 mg / kg (e.g., 0.1 mg / kg to 1 mg / kg, e.g., 0.3 mg / kg), for example, once every three weeks. In one embodiment, the TGF-β inhibitor (e.g., XOMA089) is administered intravenously.

[0270] In one embodiment, a TGF-β inhibitor (e.g., XOMA089) is administered intravenously, for example, in doses of 0.1 mg / kg to 15 mg / kg (e.g., 0.3 mg / kg to 12 mg / kg or 1 mg / kg to 6 mg, e.g., about 0.1 mg / kg, 0.3 mg / kg, 1 mg / kg, 3 mg / kg, 6 mg / kg, 12 mg / kg or 15 mg / kg), for example, once every three weeks, and a PD-1 inhibitor (e.g., an anti-PD-1 antibody molecule) is administered intravenously, for example, in doses of 50 mg to 500 mg (e.g., doses of 100 mg to 400 mg, e.g., about 100 mg, 200 mg, 300 mg or 400 mg), for example, once every three weeks or once every four weeks, for example, by intravenous infusion. In one embodiment, a PD-1 inhibitor (e.g., an anti-PD-1 antibody molecule) is administered in doses of 100 mg to 300 mg (e.g., doses of approximately 100 mg, 200 mg, or 300 mg), for example, once every three weeks, for example, by intravenous infusion.

Adenocarcinoma includes malignant tumors such as most colon cancers, rectal cancers, renal cell carcinomas, liver cancers, non-small cell lung cancers, small intestine cancers, and esophageal cancers. Squamous cell carcinoma includes, for example, malignant tumors of the lungs, esophagus, skin, head and neck region, oral cavity, anus, and cervix. Metastatic lesions of the above cancers can also be treated or prevented using the methods, combinations, and compositions of the present invention.

[0354] As used herein, the term "subject" is intended to include both humans and non-human animals.

[0355] In one embodiment, the combination therapy described herein comprises a composition of the present invention co-formulated and / or co-administered with one or more further therapeutic agents, such as one or more anticancer agents, cytotoxic or cell proliferation inhibitors, hormonal treatments, vaccines and / or other immunotherapies. In other embodiments, the combination is further administered or used in combination with other therapeutic modalities, including surgery, radiation, cryosurgery and / or hyperthermia. In one embodiment, such combination therapy can take advantage of therapeutic agents administered at lower doses and thus avoid the potential toxicity or complications associated with various monotherapies.

[0356] In one embodiment, when administered as a combination, a PSMA therapeutic agent or further therapeutic agent, such as radiolabeled compound I, may be administered individually, for example, in an amount or dose higher, lower, or the same as each agent used as a monotherapy. In one embodiment, the amount or dose administered of the PSMA therapeutic agent or further therapeutic agent, such as radiolabeled compound I, is lower (e.g., at least 20%, at least 30%, at least 40%, or at least 50%) than the amount or dose administered of each agent used as a monotherapy. In another embodiment, the amount or dose of the PSMA therapeutic agent or further therapeutic agent, such as radiolabeled compound I, that produces the desired effect (e.g., cancer treatment) is low (e.g., at least 20%, at least 30%, at least 40%, or at least 50%).

[0357] Pharmaceutical composition In other embodiments, the present invention provides compositions, e.g., pharmaceutically acceptable compositions, comprising one or more, e.g., two, three, four, five, six, seven, eight or more, of the PSMA therapeutic agents or further therapeutic agents described herein, such as radiolabeled compound I, either alone or together with a pharmaceutically acceptable carrier. **Polarity of use herein** includes any and all physiologically compatible solvents, dispersion media, isotonic and absorption retardants, etc. In some embodiments, the carrier may be suitable for intravenous, intramuscular, subcutaneous, non-enteral, rectal, spinal, or epithelial administration (e.g., by injection or infusion).

[0358] The compositions described herein may be in a variety of forms. Various embodiments include, for example, solutions (e.g., injectable and infusible solutions), dispersions or suspensions, liquid, semi-solid and solid dosage forms such as liposomes and suppositories. The form depends on the intended method of administration and therapeutic application. In some embodiments, the composition is in the form of an injectable or infusible solution. In some embodiments, the method of administration is non-enteral (e.g., intravenous, subcutaneous, intraperitoneal, or intramuscular). In some embodiments, the composition is administered by intravenous infusion or injection. In other embodiments, the composition is administered by intramuscular or subcutaneous injection.

[0359] As used herein, the terms “non-enteral administration” and “administer non-enterally” mean methods of administration other than enteral and local administration, usually by injection, and include, but are not limited to, intravenous, intramuscular, intra-arterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subepidermal, intra-articular, subcapsular, subarachnoid, intrathecal, epidural, and intrasternal injections and infusions.

[0360] In some embodiments, the therapeutic composition must be sterile and stable under manufacturing and storage conditions. In various embodiments, the composition may be formulated as a solution, microemulsion, dispersion, liposome, or other regular structure. In some embodiments, the composition is suitable for high antibody concentrations. A sterile injection solution may be prepared by incorporating the required amount of the active compound into a suitable solvent containing, as needed, one or a combination of the components listed above, followed by filtration sterilization. In some embodiments, a dispersion is prepared by incorporating the active compound into a sterile medium containing a basic dispersion medium and other necessary components from those listed above. For sterile powders for preparing sterile injection solutions, suitable preparation methods are vacuum drying and freeze-drying, which yield a powder of the active component and any further desired components from a pre-sterilically filtered solution. In some embodiments, the proper fluidity of the solution may be maintained, for example, by the use of a coating such as lecithin, in the case of a dispersion by maintaining the required particle size, and by the use of a surfactant. In other embodiments, long-term absorption of the injection composition may be achieved by adding absorption-delaying agents, such as monostearate and gelatin, to the composition.

In other embodiments, a PSMA therapeutic agent such as radiolabeled compound I or other therapeutic agents can be administered by intravenous infusion to reach a dose of less than 10 mg / min, e.g., at a rate of 10 mg / min or less, about 1 - 100 mg / m 2 , e.g., about 5 - 50 mg / m 2 , about 7 - 25 mg / m 2 or about 10 mg / m 2 It should be noted that the dosage values can vary depending on the type and severity of the condition to be alleviated. For any particular subject, the specific dosing regimen should be adjusted by the professional judgment of the person administering or supervising the administration of the composition, and it is also understood that the dosage ranges shown herein are merely exemplary and are not intended to limit the scope or practice of the compositions of the present application.

[0412] The pharmaceutical composition of the present invention may contain a "therapeutic effective dose" or "preventive effective dose" of a PSMA therapeutic agent such as radiolabeled compound I or other therapeutic agents. "Therapeutic effective dose" refers to an effective amount in the dosage and duration required to achieve the desired therapeutic outcome. The therapeutic effective dose of a PSMA therapeutic agent such as radiolabeled compound I or other therapeutic agents may vary depending on factors such as the individual's disease state, age, sex, and weight, and the ability of the PSMA therapeutic agent such as radiolabeled compound I or other therapeutic agent to induce the desired response in the individual. The therapeutic effective dose is also such that the therapeutic benefits outweigh any toxic or adverse effects of the PSMA therapeutic agent such as radiolabeled compound I or other therapeutic agent. A "therapeutic effective dose" can inhibit measurable parameters, such as tumor growth rate, by at least about 20%, at least about 40%, at least about 60%, or at least about 80% compared to an untreated subject. Measurable parameters of a PSMA therapeutic agent such as radiolabeled compound I or other therapeutic agent, such as the ability to inhibit cancer, can be evaluated in animal model systems that predict efficacy in human tumors. Alternatively, this property of the composition can be evaluated by testing the in vitro inhibitory capacity of a PSMA therapeutic agent, such as radiolabeled compound I, or other therapeutic agents, by assays known to those skilled in the art.

[0413] "Prophylactic effective dose" refers to the effective amount of dosage and duration required to achieve the desired preventive outcome. Typically, since prophylactic doses are used for pre-disease or early-stage conditions, the prophylactic effective dose is less than the therapeutic effective dose.

The full scope of the invention should be determined by considering the claims and specification, along with such variations and the full scope of equivalents. [Examples]

[0417] Radiolabeled compound I can be prepared by the method described in WO2015055318, which is incorporated herein by reference for the preparation of radiolabeled compound I, particularly compound Ia. The preparation of radiolabeled compound Ia is abbreviated below.

[0418] Example 1: Synthesis of Compound Ia The glutamyl isocyanate was produced in situ by adding a mixture of 3 mmol of bis(tert-butyl) L-glutamate hydrochloride and 1.5 mL of N-ethyldiisopropylamine (DIPEA) in 200 mL of dry CH2CI2 to 1 mL of dry CH2CI2 solution of 1 mmol of triphosgene over 4 hours at 0°C. After stirring the reaction mixture at 25°C for 1 hour, 0.5 mmol of resin immobilization (2-chloro-trityl resin) 4 mL of DCM solution of ε-allyloxycarbonyl protected lysine was added, and the mixture was reacted for 16 hours with gentle stirring. The resin was filtered off, and the allyloxy protecting group was removed by using a 4 mL CH2CI2 solution of 30 mg of tetrakis(triphenyl)palladium(0) and 400 pL of morpholine for 3 hours. The coupling of Fmoc-3-(2-naphthyl)-L-alanine and trans-4-(Fmoc-aminomethyl)cyclohexanecarboxylic acid was carried out stepwise using 2 mmol of Fmoc protective acid, 1.96 mmol of HBTU, and 2 mmol of N-ethyldiisopropylamine in a final volume of 4 mL of DMF. After activation with 3.95 equivalents of HBTU and DIPEA for 2 hours, 4 equivalents of tris(t-bu)-DOTA (Chematech) were reacted with the resin packing for 3 hours in a final volume of 3 mL of DMF. The product was cleaved from the resin in a 2 mL mixture of trifluoroacetic acid, triisopropylsilane, and water (95:2.5:2.5). Purification was performed using RP-HPLC, and the purified product was analyzed by analytical RP-HPLC and MALDI-MS.

[0419] Example 2: Radiolabeling of compound Ia 177 Lu label: 177Lu (approximately 100 MBq) was mixed with 200 μI of 0.4 M sodium acetate buffer containing Chelex (pH=5). A 1 mM solution of compound I in 10 μI of 10% DMSO aqueous solution, 2 μI of saturated ascorbic acid solution, and 40 μI of [unclear text] were also mixed. 177 The solution containing Lu was mixed and stirred at 95°C for 10 minutes. Labeling was confirmed by radio-HPLC (within 5 minutes using an aqueous solution of 0-100% ACN, Monolith column).
