First seen Nov 01, 2025 · Last updated Apr 29, 2026 · Updated 24 times

Summary

This early-stage study tests whether combining vorasidenib (a targeted therapy) with pembrolizumab (an immunotherapy) is safe and can boost the immune system's attack on recurrent IDH-1 mutant gliomas, a type of brain tumor. About 60 adults with grade 2 or 3 tumors will receive the drugs before and after surgery. The main goals are to check for side effects and measure immune cells in the tumor tissue.
