New pill targets hard-to-treat cancers with specific gene flaw
NCT ID NCT07284186
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new experimental drug called PLX-61639 for people with advanced solid tumors that have a specific genetic change (SMARCA4 mutation) and have stopped responding to standard treatments. The drug is taken as a daily pill and aims to shrink or control the cancer. About 155 adults will take part to see if the drug is safe and how well it works.
