What was measured

Time from first dose to death due to any cause in the LGG cohort. Confidence Intervals were estimated using the Brookmeyer Crowley method. If a patient was not known to have died at the time of analysis cut-off, OS was censored at the date of last contact.

Analysis population: All participants on the LGG cohort to whom study treatment had been assigned by randomization regardless of whether or not treatment was administered. According to the intent to treat principle, patients were analyzed according to the treatment they had been assigned to during the randomization procedure.

Groups in this outcome

LGG Cohort: Dabrafenib and Trametinib

Participants in the LGG cohort randomized to receive dabrafenib (orally, twice daily and dosed based on weight and age) in combination with trametinib (orally, once daily in combination with the first daily dose of dabrafenib and was dosed based on weight)

LGG Cohort: Carboplatin and Vincristine

Participants in the LGG cohort randomized to receive active comparator chemotherapy (carboplatin and vincristine). Participants received one course of induction (10 weeks of chemotherapy with 2 weeks of rest), followed by 8 cycles of maintenance chemotherapy. Participants were allowed to crossover to dabrafenib and trametinib after centrally confirmed and RANO-defined disease progression.
