Summary

This trial aims to test the safety and dosage of GS-2121 alone and with zimberelimab in patients with advanced solid tumors. The study will focus on evaluating how well the drugs are

Who is the study for?

This trial is for adults with advanced solid tumors who are eligible to receive new treatments. Specific eligibility criteria aren't provided, but typically participants must have measurable disease and adequate organ function, and cannot be receiving other cancer therapies.

What is being tested?

The study is testing GS-2121 alone or combined with zimberelimab (ZIM) in patients with advanced solid tumors. It aims to determine the safety, tolerability, and optimal dosing of these treatments.

What are the potential side effects?

While specific side effects are not listed, common ones for cancer immunotherapy like GS-2121 and ZIM may include fatigue, skin reactions, flu-like symptoms, allergic reactions, and potential autoimmune responses.
