摘要：
Provided herein are uses of fibroblast growth factor receptor 2 (FGFR2) inhibitors in cancer treatment, in some cases in combination with immune stimulating agents, such as inhibitors of PD-1 or PD-L1. In some embodiments, FGFR2 inhibitors may comprise FGFR2 antibodies or FGFR2 extracellular domain (ECD) polypeptides, or FGFR2 ECD fusion molecules comprising an FGFR2 ECD and a fusion partner. In some embodiments, PD-1/PD-L1 inhibitors may comprise anti-PD-1 antibodies such as antibodies that bind to PD-1 or to PD-L1 and inhibit interactions between these proteins, as well as PD-1 fusion proteins or polypeptides. This application also provides methods of predicting response to treatment of cancer, such as bladder or gastric cancer, with FGFR2 inhibitors by determining FGFR2 overexpression and/or gene amplification in tumor cells of cancer subjects before treatment with FGFR2 inhibitors either alone or in combination with immune stimulating agents.
