New drug targets hard-to-treat cancers with missing MTAP gene
NCT ID NCT05245500
First seen Jun 27, 2026 · Last updated Sep 03, 2026 · Updated 2 times
Summary
This early-stage trial tests an experimental drug called MRTX1719 in adults with advanced solid tumors that have a missing MTAP gene. The study aims to find a safe dose and see if the drug can shrink tumors or slow their growth. About 336 participants with cancers like mesothelioma, lung cancer, or pancreatic cancer will take part.
