Abstract: The disclosure provides a method for immunotherapy of a subject afflicted with cancer, comprises administering to the subject a composition comprising a therapeutically effective amount of an antibody that inhibits signaling from the PD-1/PD-L1 signaling pathway. This disclosure also provides a method for immunotherapy of a subject afflicted with cancer comprising selecting a subject that is a suitable candidate for immunotherapy based on an assessment that the proportion of cells in a test tissue sample from the subject that express PD-L1 on the cell surface exceeds a predetermined threshold level, and administering a therapeutically effective amount of an anti-PD-1 antibody to the selected subject. The invention additionally provides rabbit mAbs that bind specifically to a cell surface-expressed PD-L1 antigen in a FFPE tissue sample, and an automated IHC method for assessing cell surface expression in FFPE tissues using the provided anti-PD-L1 Abs.

Abstract: The disclosure provides a method for immunotherapy of a cancer patient, comprises administering to the patient an Ab that inhibits signaling from the PD-1/PD-L1 signaling pathway, or a combination of such Ab and an anti-CTLA-4 Ab. This disclosure also provides a method for immunotherapy of a cancer patient comprising selecting a patient who is a suitable candidate for immunotherapy based on an assessment that the proportion of cells in a test tissue sample from the patient that express PD-L1 on the cell surface exceeds a predetermined threshold level, and administering an anti-PD-1 Ab to the selected subject. The disclosure additionally provides rabbit mAbs that bind specifically to a cell surface-expressed PD-L1 antigen in a FFPE tissue sample, and an automated IHC method for assessing cell surface expression in FFPE tissues using the provided anti-PD-L1 Abs.

Abstract translation: 本公开提供了一种用于癌症患者的免疫治疗的方法，包括向患者施用抑制PD-1 / PD-L1信号传导途径的信号传导的Ab，或该抗体与抗CTLA-4Ab的组合。 本公开还提供了一种用于癌症患者的免疫治疗的方法，包括选择作为免疫治疗的合适候选者的患者，该评估基于来自表达细胞表面上的PD-L1的患者的来自患者的测试组织样品中细胞的比例超过 预定阈值水平，以及对所选择的受试者施用抗PD-1Ab。 本公开另外提供了与FFPE组织样品中的细胞表面表达的PD-L1抗原特异性结合的兔mAb，以及使用所提供的抗PD-L1抗体评估FFPE组织中的细胞表面表达的自动化IHC方法。

Abstract: The invention provides a method of treating a tumor in a human patient comprising (i) identifying a patient as having a LAG-3 positive tumor and (ii) administering to the patient a PD-1 pathway inhibitor, a combination of a PD1 pathway inhibitor and an immune checkpoint inhibitor, a combination of a LAG-3 inhibitor and a PD-1 pathway inhibitor, or an anti-CTLA4 antibody. In some embodiments, the method further comprises identifying the patient as having a LAG-3 positive PD-L1 positive tumor. In some embodiments, the LAG-3 inhibitor is an anti-LAG-3 antibody and the PD-1 pathway inhibitor is an anti-PD-1 antibody. The methods of the invention can improve response rates to treatment with a PD-1 pathway inhibitor, a combination of a PD1 pathway inhibitor and an immune checkpoint inhibitor, or a combination of a LAG-3 inhibitor and a PD-1 pathway inhibitor.
