Phase 1 Study Evaluating the Safety and PK of ADU-1805 in Advanced Solid Tumors

This study is designed to evaluate the safety, PK, PD and preliminary clinical activity of ADU-1805, an anti- SIRPα monoclonal antibody, as monotherapy and in combination with pembrolizumab (anti-PD-1 antibody). The study is divided into a dose escalation phase and a dose expansion phase. The dose expansion phase investigates ADU-1805 plus pembrolizumab at the respective recommended phase 2 dose (RP2D) in four advanced solid tumors: advanced PD-(L)1-naïve MSS colorectal cancer (CRC), PD-1 relapsed/refractory patients with either advanced MSS endometrial cancer (EC), renal cell carcinoma (RCC) or non-small cell lung cancer (NSCLC) patients.
