  • Publication number: 20210011022
    Abstract: Provided herein are diagnostic antibodies that bind to glucocorticoid-induced tumor necrosis factor receptor (GITR). Such antibodies are useful for methods of detecting the expression of GITR in biological samples, for example, tumor tissue, and identifying a cancer patient likely to respond to anti-GITR immunotherapy or predicting whether a cancer patient will respond to anti-GITR immunotherapy.

  • Publication number: 20200308282
    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.
