DNA-Guided immunotherapy trial aims to match drug to tumor

NCT ID NCT04273061

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tests the immunotherapy drug atezolizumab in 200 people with advanced solid tumors (breast, lung, GI, and others). Researchers use each person's tumor DNA to see if it predicts a response. Participants get the same dose every 3 weeks. The goal is to see if DNA analysis can help select who benefits most.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Atezolizumab (TECENTRIQ), an immunotherapy drug given by IV every 3 weeks

What this could lead to

If successful, this could show that analyzing a tumor's DNA can predict which patients will benefit from atezolizumab, leading to more personalized cancer treatment.

What could go wrong

This is an early Phase 2 trial with small groups per cancer type, so results may not apply broadly. Not all participants will respond, and side effects from immunotherapy can be serious.
