NCT ID NCT05990738

First seen Jun 27, 2026 · Last updated Aug 05, 2026 · Updated 5 times

Summary

This early-stage trial tests a new antibody-like drug called BI 764532 alongside standard chemotherapy in adults with advanced small cell lung cancer that has returned after platinum-based treatment. The main goal is to find a safe dose and check for side effects. About 69 participants will receive the combination and be monitored regularly.

What this could mean

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

Active substance
BI 764532 (Obrixtamig) plus topotecan or other single-agent chemotherapy
What this could lead to
If it works, this could point toward a new combination treatment for small cell lung cancer that has stopped responding to standard chemotherapy.
What could go wrong
This is an early Phase 1 safety trial with only 69 participants, so it is too small to prove effectiveness. The drug may cause side effects or fail to shrink tumors.
