One-Time immune boost for ARID1A-Mutant cancers?

NCT ID NCT06824363

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial is testing whether a single dose of two immunotherapy drugs (tremelimumab and durvalumab) can increase cancer-fighting immune cells inside tumors. It includes 34 people with untreated, non-metastatic stomach or esophageal cancers that have an ARID1A gene mutation. The main goal is to see if the treatment is feasible and changes the tumor's immune environment.

What this could mean

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

Active substance

Tremelimumab and Durvalumab (two immunotherapy drugs given as a single dose)

What this could lead to

If successful, this could point toward a new treatment option for people with hard-to-treat stomach and esophageal cancers that have a specific genetic mutation (ARID1A).

What could go wrong

This is a very early, small proof-of-principle study with only 34 people. It is designed to see if the drugs increase immune cells in the tumor, not yet to prove they shrink tumors or extend life. Immune checkpoint inhibitors can cause serious immune-related side effects.
