Primary Outcome Measures

Name	Time	Method
Part 1: Progression Free Survival (PFS) by Blinded Independent Review Committee (BIRC) in Combo 450 Group as Compared to Vemurafenib Group	From randomization until documented disease progression (PD), initiation of new anti-cancer therapy, censoring date or death, whichever occurred first (up to 29 months)	PFS was defined as the time from the date of randomization to the date of the first documented disease progression (PD) or death due to any cause, whichever occurs first. PFS was determined based on tumor assessment (RECIST version 1.1 criteria) as per BIRC/central review and survival information. If a participant did not had an event at the time of the analysis cut-off or at the start of any new anti-cancer therapy, data was censored at the date of last adequate tumor assessment. PD was defined as at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20%, the sum must demonstrate an absolute increase of at least 5 square millimeter (mm\^2).

Other items include physical, functional and social/family well-being (7 items each),emotional well-being (6 items),surgery specific concerns related to melanoma(8 items,not included in this study). Each item range from 0(not at all) to 4(very much), combined to produce subscale scores.Total score range for FACT-M excluding surgery specific items is 0 to 172,higher scores represent better quality of life.Melanoma subscale score range from 0(worst response) to 64(best response),higher score indicated better quality of life. Time to definitive 10% deterioration:time from date of randomization to date of event with at least 10% relative to baseline worsening of corresponding scale score with no later improvement or death due to any cause.

DOR was estimated for responders (i.e. participants achieving at least once CR or PR) only using a Kaplan-Meier method. CR was defined as disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \<10 mm. PR was defined as at least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. If a participant with a CR or PR had no progression or death due to underlying disease, the participant was censored at the date of last adequate tumor assessment. Results are based on confirmed BIRC response.
Part 1 and Part 2: Change From Baseline in the Function Assessment Cancer Therapy-melanoma (FACT-M) Subscale at Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and End of Treatment Visit	Baseline (Day 1 of Cycle 1), Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and end of treatment visit (within14 days after the last dose of study drug)	FACT-M: melanoma specific questionnaire to assess participant health-related quality of life. Melanoma specific subscale consists of 16 items related to signs, symptoms, physical/social activities most relevant to participants with advanced-stage melanoma. Other items include physical, functional and social/family well-being (7 items each),emotional well-being (6 items),surgery specific concerns related to melanoma(8 items, not included in this study). Each item range from 0(not at all) to 4(very much), combined to produce subscale scores. Total score range for FACT-M excluding surgery specific items is 0 to 172,higher scores represented better quality of life. Melanoma subscale score range from 0(worst response) to 64(best response),higher score indicated better quality of life.
Part 1 and Part 2: Change From Baseline in EuroQoL-5 Dimension-5 Level (EQ-5D-5L) Index Score at Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and End of Treatment Visit	Baseline (Day 1 of Cycle 1), Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and end of treatment visit (within14 days after the last dose of study drug)	EQ-5D-5L is a standardized participant completed questionnaire that measures health status in terms of a single index value or utility score. EQ-5D-5L consisted of two components: a health state profile (descriptive system) and a visual analogue scale (VAS) in which participants rate their overall health status from 0 (worst imaginable) to 100 (best imaginable), where higher scores indicated better health status. EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 response levels: 1=no problems, 2=slight problems, 3=moderate problems, 4=severe problems and 5=extreme problems. EQ-5D-5L health status index score range between 0 to 1. Higher score indicated better health status.
Part 1 and Part 2: Change From Baseline in Emotional Functioning Scale Score of the EORTC QLQ-C30 at Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and End of Treatment Visit	Baseline (Day 1 of Cycle 1), Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and end of treatment visit (within14 days after the last dose of study drug)	EORTC QLQ-C30 contains 30 items and is composed of multi-item and single-item measures. These include 5 functional scales (physical, role, emotional, cognitive and social functioning), 3 symptom scales (fatigue, nausea/vomiting, and pain), 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial impact) and a global health status/quality of life (QOL) scale. The questionnaire employs 28 4-point Likert scales with responses from "not at all" to "very much" and two 7-point Likert scales for global health and overall QOL. Responses to all items converted to 0 to 100 scale. For functional and global QOL scales, higher scores represent a better level of functioning/QOL. For symptom-oriented scales, a higher score represented more severe symptoms.
Part 1 and Part 2: Change From Baseline in Physical Functioning Scale Score of the EORTC QLQ-C30 at Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and End of Treatment Visit	Baseline (Day 1 of Cycle 1), Day 1 of Cycle 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25 and end of treatment visit (within14 days after the last dose of study drug)	EORTC QLQ-C30 contains 30 items and is composed of multi-item and single-item measures.
