Triple-Drug attack on Hard-to-Treat stomach cancer shows promise in early trial

NCT ID NCT07176312

First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 4 times

Summary

This Phase II trial is testing a combination of three drugs—zanidatamab, pembrolizumab, and chemotherapy—in 80 people with advanced stomach or esophageal cancer that has spread and tests positive for HER2 and PD-L1. The goal is to see if this triple therapy can keep the cancer from growing for at least 12 months. All participants receive the same treatment, and the study is currently recruiting.

What this could mean

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

Active substance

Zanidatamab (a targeted antibody), pembrolizumab (an immunotherapy), and chemotherapy (mFOLFOX)

What this could lead to

If successful, this combination could offer a new first-line treatment option for people with HER2 and PD-L1 positive metastatic gastroesophageal cancer, potentially improving how long they live without the disease getting worse.

What could go wrong

This is an early Phase II trial with only 80 participants and no comparison group, so results may not be definitive. The combination of three drugs may cause significant side effects, and not all patients will respond.
