Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Is the new drug, RP-6306, safe to use, and what effects does it have on cancer when given with standard treatment?
* If there are specific biomarkers, do patients have an improved response to treatment compared to those without the biomarker?
This study is being done to find out if this approach is better or worse than the usual approach for this type of cancer. The usual approach is defined as care most people get for this type of cancer.
