RARE-09. EFFICACY AND SAFETY OF DABRAFENIB + TRAMETINIB IN PATIENTS WITH RECURRENT/REFRACTORY BRAF V600E–MUTATED HIGH-GRADE GLIOMA (HGG)

ABSTRACT: Abstract

BACKGROUND

Current treatment outcomes for patients with recurrent HGG are poor, with median progression-free survival (PFS) and overall survival (OS) of 2.5 and 7.5 months, respectively. Dabrafenib (BRAF inhibitor) + trametinib (MEK inhibitor) resulted in an intracranial overall response rate (ORR) of 58% in BRAF V600–mutated melanoma brain metastases. Dabrafenib + trametinib was evaluated as treatment for patients with BRAF V600E–mutated HGG.

METHODS

In this phase 2, open-label trial (NCT02034110), patients with BRAF V600E mutations in 9 rare tumor types, including HGG, received continuous dabrafenib (150 mg BID) + trametinib (2 mg QD) until unacceptable toxicity, disease progression, or death. For the HGG cohort, eligible patients had histologically confirmed r
