Study of MK-4280 as Monotherapy and in Combination With Pembrolizumab (MK-3475) With or Without Chemotherapy AND MK-4280A as Monotherapy in Adults With Advanced Solid Tumors (MK-4280-001)

Brief description of study

This is a safety and pharmacokinetics study of MK-4280 as monotherapy and in combination with pembrolizumab (MK-3475) AND MK-4280A as monotherapy in adults with metastatic solid tumors for which there is no available therapy which may convey clinical benefit. Part A of this study is a dose escalation design in which participants receive MK-4280 as monotherapy or MK-4280 in combination with pembrolizumab. Part B is a dose confirmation design to estimate the recommended Phase 2 dose (RPTD), as determined by dose-limiting toxicity, for MK-4280 in combination with pembrolizumab in participants with advanced solid tumors. Part B will also assess the efficacy of MK-4280 as monotherapy and in combination with pembrolizumab with and without chemotherapy AND MK-4280A as monotherapy in expansion cohorts.
