First seen Jun 24, 2026 · Last updated Jul 29, 2026 · Updated 5 times
Summary
This early-stage trial is testing an experimental drug called RO7566802, alone or with the immunotherapy atezolizumab, in people with advanced solid tumors that have not responded to standard treatments. The study aims to find a safe dose and check for early signs of activity. About 250 participants will take part in this first-in-human study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- RO7566802 (an experimental drug) and atezolizumab (Tecentriq, an immunotherapy)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced solid tumors that have stopped responding to standard therapies.
- What could go wrong
- This is a very early (Phase 1) trial, so the main goal is safety, not effectiveness. The drug may not work or could have serious side effects.
