Time frame
From randomization until censoring date/death, whichever occurred first (up to 117.8 months [M] of treatment exposure for LGX818 +MEK162; up to 111.4 months of treatment exposure for LGX818; up to 110.5 months of treatment exposure for Vemurafenib)

What was measured

Overall survival was defined as the time from the date of randomization to the date of death due to any cause. If a death was not observed by the date of analysis cutoff, OS was censored at the date of last contact.

Analysis population: FAS included all randomized participants.

Groups in this outcome

Part 1: LGX818 450 mg QD+MEK162 45 mg BID (Combo 450)

Participants received 450 milligram (mg) of LGX818 orally once daily (QD) along with 45 mg of MEK162 twice daily (BID) for each 28 day treatment cycle until progressive disease (PD) as confirmed by Blinded Independent Review Committee (BIRC), withdrawal of consent, intolerable toxicity, study discontinuation, lost to follow-up or death.

Part 1: LGX818 300 mg

Participants received 300 mg of LGX818 orally once daily for each 28 day treatment cycle until PD as confirmed by BIRC, withdrawal of consent, intolerable toxicity, study discontinuation, lost to follow-up or death.

Part 1: Vemurafenib 960 mg BID

Participants received 960 mg of Vemurafenib according to the locally approved prescribing information twice daily for each 28 day treatment cycle until PD as confirmed by BIRC, withdrawal of consent, intolerable toxicity, study discontinuation, lost to follow-up or death.
