Double/Triple Combinations of AN2025, AN0025 and Atezolizumab in Advanced Solid Tumors

This is an open-label, multicenter, Phase 1a study to evaluate the safety, tolerability, PK and preliminary efficacy of AN2025 and AN0025 in double or triple combination treatments with Atezolizumab in patients with locally advanced/metastatic tumors. This study consists of three DLT Observation Periods I, II and III. Observations I and II are double combination treatments, which will be conducted in parallel, whereas Observation III (the triple combination treatment) will be initiated only after a thorough review of the safety data from Observations I and II. In all three Observation Periods, a "6 + 3 design" will be utilized for dose finding with dose escalation and de-escalation.
