Summary

This phase 3 trial is testing whether a combination of three drugs (disitamab vedotin, trastuzumab, and tislelizumab) works better than standard chemotherapy plus trastuzumab with or without pembrolizumab for people with advanced HER2-high stomach or gastroesophageal junction cancer. The study will enroll 555 participants who have not had prior treatment for advanced disease. The main goal is to see if the new combo delays cancer progression or improves survival.

What this could mean

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

Active substance
Disitamab vedotin, trastuzumab, tislelizumab, CAPOX chemotherapy, pembrolizumab
What this could lead to
If this works, it could offer a more effective first-line treatment option for people with advanced HER2-high stomach cancer, potentially extending life without progression.
What could go wrong
This is an early-stage phase 3 trial with 555 participants, so results are not yet known. The new combination may not be better than standard therapy and could have more side effects.
