Novartis announced the U.S. Food and Drug Adminiration (FDA) granted approval for Tafinlar(R) (dabrafenib)+ Mekinist(R) (trametinib) for the treatment of pediatric patients 1 year of age and older with low-grade glioma (LGG) with a BRAF V600E mutation who require systemic therapy. The FDA also approved liquid formulations of Tafinlar and Mekinist, marking the first time a BRAF/MEK inhibitor has been developed in a formulation suitable for patients as young as one year of age. These approvals make Tafinlar + Mekinist the first and only approved combination targeted therapy to treat pediatric patients with BRAF V600E LGG.

This FDA approval of Tafinlar + Mek inist is based on results from the Phase II/III TADPOLE trial (NCT02684058) that showed patients randomized to receive Tafinlar + Mek Inist experienced a statistically significant improvement in overall response rate (ORR) of 47% (CI: 35-59%) compared to 11% (CI: 3-25%) for those randomized to receive chemotherapy. At a median follow-up of 18.9 months, median progression-free survival (PFS) was 20.1 months with Tafinlar + MekINist (CI: 12.8 months-not estimable) compared to 7.4 months with chemotherapy (CI: 3.6-11.8 months, hazard ratio=0.31 [CI: 0.17-0.55] [p<0.001).
