| Abstract Text | Pediatric low-grade glioma (pLGG) is the most prevalent childhood brain tumor. Patients with BRAF V600 mutation-positive pLGG may benefit from treatment with dabrafenib. Part 2 of a phase I/IIa study, open-label study (NCT01677741) explores the activity and safety of dabrafenib treatment in these patients.Patients ages 1 to <18 years who had BRAF V600-mutant solid tumors (≥1 evaluable lesion) with recurrent, refractory, or progressive disease after ≥1 standard therapy were treated with oral dabrafenib 3.0 to 5.25 mg/kg/day (part 1) or at the recommended phase II dose (RP2D; part 2). Primary objectives were to determine the RP2D (part 1, results presented in a companion paper) and assess clinical activity (part 2). Here, we report the clinical activity, including objective response rates (ORRs) using Response Assessment in Neuro-Oncology criteria and safety across parts 1 and 2.Overall, 32 patients with pLGG were enrolled (part 1, n = 15; part 2, n = 17). Minimum follow-up was 26.2 months. Among all patients, the ORR was 44% [95% confidence interval (CI), 26-62] by independent review. The 1-year progression-free survival rate was 85% (95% CI, 64-94). Treatment-related adverse events (AE) were reported in 29 patients (91%); the most common was fatigue (34%). Grade 3/4 treatment-related AEs were reported in 9 patients (28%).Dabrafenib demonstrated meaningful clinical activity and acceptable tolerability in patients with BRAF V600-mutant pLGG. | ||||||||||||

| BRAF V600X | low grade glioma | predicted - sensitive | Dabrafenib | Phase Ib/II | Actionable | In a Phase I/II trial, Tafinlar (dabrafenib) treatment was well tolerated and demonstrated preliminary efficacy, resulted in an objective response rate of 44% (14/32, 1 complete response, 13 partial response) and a disease control rate of 78% (25/32), with a median duration of response of 26 months in pediatric patients with BRAF V600-mutant low-grade gliomas (PMID: 31811016; NCT01677741). | 31811016 |
| BRAF V600X | ganglioglioma | predicted - sensitive | Dabrafenib | Case Reports/Case Series | Actionable | In a Phase I/II trial, Tafinlar (dabrafenib) treatment resulted in a partial response in a pediatric patient with BRAF V600-mutant ganglioglioma (PMID: 31811016; NCT01677741). | 31811016 |
