Study of S-531011 for Advanced Solid Tumors

This study is testing a new drug called S-531011, alone and in combination with other approved cancer medicines like pembrolizumab and bevacizumab, for people with advanced or metastatic (spread) solid tumors. You might be eligible if you have solid tumors that have returned or spread, and you have no standard treatment options, or you can't tolerate them. The study aims to find a safe dose of S-531011 and see how well these treatments shrink tumors. Researchers are also looking at specific genetic markers (biomarkers) like BRAF, EGFR, KRAS, and NRAS in your tumor. The study plans to enroll 282 participants.

Study design
This is an interventional study with an unclear phase, meaning it's testing a treatment. It plans to enroll 282 participants.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Your response to treatment will be measured every 6 weeks for the first 24 weeks, then every 9 weeks until your disease progresses, for approximately 12 to 24 months.
