A Phase II Study of Dabrafenib plus Trametinib after Radiation Therapy for Newly Diagnosed High-Grade Glioma


Full Title

ACNS1723: A Phase 2 Study of Dabrafenib (NSC# 763760) with Trametinib (NSC# 763093) after Local Irradiation in Newly Diagnosed BRAFV600-Mutant High-Grade Glioma (HGG) (IND #145355) (CIRB)


The purpose of this study is to assess the safety and effectiveness of giving the drugs dabrafenib and trametinib after radiation therapy in children, adolescents, and young adults with newly diagnosed high-grade glioma that has been surgically removed and contains a particular mutation in a gene called BRAF.

Dabrafenib works by blocking the mutated BRAF protein, which lets cancer cells grow without stopping. Trametinib blocks another protein, called MEK, which also fuels cancer cell growth. Both medications are taken orally (by mouth).
