Official title
A Phase 1 Study to Evaluate the Safety and Tolerability of GS-4528 as Monotherapy and in Combination With an Anti-PD-1 Monoclonal Antibody in Adults With Advanced Solid Tumors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goals of this clinical study are to identify if GS-4528 alone or in combination with anti-programmed cell death protein 1 (PD-1) (Anti-PD-1) Monoclonal Antibody is safe and tolerable in people with solid tumors and to identify the recommended dose of GS-4528 for further development that is safe to give to people alone or in combination with Anti-PD-1 Monoclonal Antibody. The primary objectives of this study are: * To assess the safety and tolerability of GS-4528 as monotherapy and in combination with Anti-PD-1 Monoclonal Antibody in participants with advanced solid tumors. * To identify the maximum tolerated dose (MTD)/maximum administered dose (MAD) and/or the recommended Phase 2 dose (RP2D) of GS-4528 as monotherapy and in combination with Anti-PD-1 Monoclonal Antibody in participants with advanced solid tumors.
