Immunotherapy shows promise for rare cancers in new trial

NCT ID NCT06333314

First seen Jan 03, 2026 · Last updated May 14, 2026 · Updated 26 times

Summary

This study tests whether the immunotherapy drug dostarlimab works better than standard chemotherapy as the first treatment for people with advanced cancers that have specific genetic markers (dMMR/MSI). The cancers studied are rare types like pancreatic, stomach, and small bowel cancers, but not colorectal or endometrial. About 120 adults will be randomly assigned to receive either dostarlimab or chemo, and those on chemo whose cancer gets worse may switch to dostarlimab.
