New cancer drug enters early human testing for advanced solid tumors
NCT ID NCT07438782
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This early-phase study tests a new drug called GSK5533524, alone or with other cancer treatments, in adults with advanced solid tumors that have stopped responding to standard therapies. The main goals are to find a safe dose and see if the drug can shrink tumors or slow cancer growth. About 97 participants will take part to help researchers decide the best dose for future studies.
