New drug cocktail shows promise in shrinking esophageal tumors before surgery
NCT ID NCT07244978
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial will test whether adding the experimental drug ivonescimab to standard chemotherapy before surgery can improve outcomes for people with resectable esophageal squamous cell carcinoma. About 49 participants will receive three cycles of the combination, then undergo surgery. The main goal is to see how many patients have no cancer cells left in their removed tissue (pathological complete response).
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ivonescimab (a bispecific antibody targeting PD-1 and VEGF) combined with chemotherapy (albumin paclitaxel and carboplatin)
- What this could lead to
- If successful, this combination could become a new standard pre-surgery treatment to improve tumor clearance and long-term survival for esophageal cancer patients.
- What could go wrong
- This is a small, early-phase exploratory study (49 participants) with no control group, so results may not be definitive. The combination may cause significant side effects, and not all patients may benefit.
