New antibody drug aims to stop lung cancer relapse in its tracks
NCT ID NCT07010263
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This Phase 3 trial is testing whether AK112 (Ivonescimab), a bispecific antibody that targets both PD-1 and VEGF, can help prevent cancer progression in people with limited-stage small-cell lung cancer who have completed chemoradiation. About 560 participants will receive either AK112 or a placebo every three weeks. The study measures how long patients live without their cancer worsening and overall survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AK112 (Ivonescimab), a bispecific antibody targeting PD-1 and VEGF
- What this could lead to
- If successful, this could provide a new consolidation treatment option to delay cancer progression and improve survival for patients with limited-stage small-cell lung cancer.
- What could go wrong
- This is a Phase 3 trial, but results are not yet known. The drug may not improve outcomes over placebo, and side effects from immune activation or anti-VEGF effects could occur.
