What was measured

ORR is defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR). A participant was defined as a responder if he/she sustained a complete response (CR: the disappearance of all target lesions and any pathological lymph nodes must have a short axis of \<10 mm and the disappearance of all non-target lesions) or partial response (PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters or the persistence of 1 or more non-target lesions or lymph nodes identified as a site of disease at Baseline with a short axis of ≥10mm). Only descriptive analysis performed.

Analysis population: Intent-to-Treat (ITT) Population was considered. Only participants with measurable disease at Baseline per RECIST were analyzed.

Groups in this outcome

Dabrafenib + Trametinib

Participants received dabrafenib 150 milligram (mg) HPMC capsules orally twice daily (BID), once in the morning and a second dose approximately 12 hours after the morning dose, and trametinib 2 mg once daily in the morning. Treatment was continued until disease progression, death, unacceptable toxicity, or withdrawal of consent.

Dabrafenib + Placebo

Participants received dabrafenib 150 mg HPMC capsules orally BID, once in the morning and a second dose approximately 12 hours after the morning dose, and trametinib placebo once daily in the morning. Treatment was continued until disease progression, death, unacceptable toxicity, or withdrawal of consent. Crossover to the combination therapy arm was allowed for subjects still receiving study treatment on the dabrafenib monotherapy arm after the positive result for the final OS analysis.
