Application Number:	15/945,011
Patent Claims:	1. An antibody that binds human PD-L1 (SEQ ID NO: 1) and human TIM-3 (SEQ ID NO: 2) comprising: a) a first heavy chain (HC) comprising the amino acid sequences of SEQ ID NO: 3, SEQ ID NO: 19, and SEQ ID NO: 22, b) a first light chain (LC) comprising the amino acid sequences of SEQ ID NO: 4 and SEQ ID NO: 27, c) a second HC comprising the amino acid sequences of SEQ ID NO: 7, SEQ ID NO: 23, and SEQ ID NO: 26, d) a second LC comprising the amino acid sequences of SEQ ID NO: 10 and SEQ ID NO: 28; and wherein, the first LC forms an inter-chain disulfide bond with the first HC, the second LC forms an inter-chain disulfide bond with the second HC, and the first HC forms two inter-chain disulfide bonds with the second HC, and the first HC and second HC are human IgG1 isotype. 2. The antibody of claim 1, wherein: a) the first HC comprises the amino acid sequences of SEQ ID NO: 20 and SEQ ID NO: 21, and b) the second HC comprises the amino acid sequences of SEQ ID NO: 24 and SEQ ID NO: 25. 3. An antibody that binds human PD-L1 (SEQ ID NO: 1) and human TIM-3 (SEQ ID NO: 2) comprising two light chains (LC) and two heavy chains (HC), wherein: a) the first LC has the amino acid sequence of SEQ ID NO: 12, b) the first HC has the amino acid sequence of SEQ ID NO: 11, c) the second LC has the amino acid sequence of SEQ ID NO: 16, SEQ ID NO: 17, or SEQ ID NO: 18, and d) the second HC has the amino acid sequence of SEQ ID NO: 13, SEQ ID NO: 14, or SEQ ID NO: 15. 4. The antibody of claim 3, wherein the second LC has the amino acid sequence of SEQ ID NO: 16, and the second HC has the amino acid sequence of SEQ ID NO: 13. 5. The antibody of claim 3, wherein the second LC has the amino acid sequence of SEQ ID NO: 17, and the second HC has the amino acid sequence of SEQ ID NO: 14. 6. The antibody of claim 3, wherein the second LC has the amino acid sequence of SEQ ID NO: 18, and the second HC has the amino acid sequence of SEQ ID NO: 15. 7. A process for producing an antibody comprising cultivating a mammalian cell, comprising (1) a DNA molecule comprising a polynucleotide sequence encoding polypeptides having the amino acid sequences of SEQ ID NO: 11, SEQ ID NO: 15, SEQ ID NO: 12, and SEQ ID NO: 18, or (2) a first DNA molecule and a second DNA molecule, wherein the first DNA molecule comprises a polynucleotide sequence encoding polypeptides having the amino acid sequence of SEQ ID NO: 11 and SEQ ID NO: 12, and wherein the second DNA molecule comprises a polynucleotide sequence encoding polypeptides having the amino acid sequence of SEQ ID NO: 15 and SEQ ID NO: 18, wherein the cell is capable of expressing the antibody of claim 6, under conditions such that the antibody is expressed, and recovering the expressed antibody. 8. An antibody produced by cultivating a mammalian cell comprising a DNA molecule comprising a polynucleotide sequence encoding polypeptides having the amino acid sequences of SEQ ID NO: 11, SEQ ID NO: 15, SEQ ID NO: 12, and SEQ ID NO: 18 under conditions such that the antibody is expressed, and recovering the expressed antibody. 9. An antibody produced by cultivating a mammalian cell comprising a first DNA molecule and a second DNA molecule, wherein the first DNA molecule comprises a polynucleotide sequence encoding polypeptides having the amino acid sequence of SEQ ID NO: 11 and SEQ ID NO: 12, and wherein the second DNA molecule comprises a polynucleotide sequence encoding polypeptides having the amino acid sequence of SEQ ID NO: 15 and SEQ ID NO: 18 under conditions such that the antibody is expressed, and recovering the expressed antibody. 10. A pharmaceutical composition, comprising the antibody of claim 3 and an acceptable carrier, diluent, or excipient. 11. A method of treating cancer, comprising administering to a patient in need thereof, an effective amount of the antibody of claim 3. 12. The method of claim 11, wherein the cancer is melanoma, lung cancer, head and neck cancer, liver cancer, colorectal cancer, pancreatic cancer, gastric cancer, kidney cancer, bladder cancer, prostate cancer, breast cancer, ovarian cancer, endometrial cancer, esophageal cancer, soft tissue sarcoma, cholangiocarcinoma, or hepatocellular carcinoma. 13. The method of claim 12, wherein the lung cancer is non-small cell lung cancer, small cell lung cancer, or mesothelioma. 14. The method of claim 11, further comprising administering simultaneously, separately, or sequentially one or more standard of care agents selected from the group consisting of cisplatin, carboplatin, dacarbazine, liposomal doxorubicin, docetaxel, cyclophosphamide and doxorubicin, navelbine, eribulin, paclitaxel, paclitaxel protein-bound particles for injectable suspension, ixabepilone, capecitabine, FOLFOX (leucovorin, fluorouracil, and oxaliplatin), FOLFIRI (leucovorin, fluorouracil, and irinotecan), gemcitabine, topotecan, liposomal irinotecan, pemetrexed, and cetuximab.
