NCT ID NCT07208136
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tests an experimental tablet, JMKX005425, in people with advanced solid tumors that have high microsatellite instability or mismatch repair deficiency. The main goals are to check the drug's safety and find the right dose. About 102 participants will take the drug by mouth, and researchers will also look for signs that the tumors shrink.
