A Study of Safety and Efficacy of KFA115 Alone and in Combo With Pembrolizumab in Patients With Select Advanced Cancers

Inclusion Criteria: * Non-small cell lung cancer with historic PD-L1 ≥ 1%, as determined locally using a clinically accepted assay. Patients must have experienced benefit from previous anti-PD(L)1-containing therapy for at least 4 months based on investigator-assessed disease stability or response prior to developing documented disease progression. Patients must have also received prior platinum-based chemotherapy, either in combination or in sequence with anti-PD-(L)1, unless patient was ineligible to receive such treatment. * Renal cell carcinoma, clear cell histology, previously treated with anti-PD(L)1-containing therapy and a VEGF targeted therapy as monotherapy or in combination. Patients should have documented disease progression following anti-PD(L)1-containing therapy. * Cutaneous melanoma, previously treated with anti-PD(L)1-containing therapy. Patients should have documented disease progression following anti-PD(L)1-containing therapy. Patients with BRAF V600-mutant melanoma must have also received prior therapy with a BRAF V600 inhibitor, with or without a MEK inhibitor. * Ovarian cancer, high-grade serous histology, naïve to anti-PD(L)1 therapy, must have received one prior systemic therapy in platinum-resistant setting. * Nasopharyngeal carcinoma, non-keratinizing locally advanced recurrent or metastatic. Depending on the study arm, patients may be naïve to anti-PD(L)1 therapy, or previously treated with platinum-based chemotherapy with or without anti-PD-(L)1.…
