Summary

This early-phase study tests an experimental drug called OKN4395, taken as a pill, alone or together with the immunotherapy pembrolizumab. The goal is to find a safe dose and see if the combination can shrink tumors in people with advanced solid cancers like lung, colorectal, stomach, or sarcoma. About 146 participants will take part across the US, Australia, UK, and EU.
