Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1 study to evaluate the safety, tolerability, PK, and preliminary efficacy of IO-108 monotherapy and in combination with anti-PD-1 monoclonal antibody pembrolizumab or tislelizumab in adult patients with advanced solid tumors. The study will be conducted in 3 parts, including Part A IO-108 monotherapy dose confirmation; Part B IO-108 + anti-PD-1 dose confirmation, and Part C dose expansion.
