What this study is about

This trial is testing a new medication called S241656 in people with certain types of cancer. The goal is to see if it's safe and how well it works when used alone or with other treatments. Participants will take the medication orally every 28 days until their cancer progresses, they experience too much side effects, or they stop participating in the trial.
