Brief Summary:
The purpose of this study is to learn about the effects of 3 study medicines (encorafenib, binimetinib, pembrolizumab) compared to 2 study medicines (ipilimumab and nivolumab) given for the treatment of melanoma.
Melanoma is a type of cancer that starts in the cells that give color to your skin.
The study is seeking participants who:
- have advanced or metastatic melanoma (has spread to other parts of the body);
- have a certain abnormal gene called "BRAF".
- have taken nivolumab or pembrolizumab treatment before this study.
Participants will either receive:
- pembrolizumab given by intravenous infusion (directly into a vein) every 3 weeks at the study clinic. Participants will also receive encorafenib and binimetinib by mouth every day at home,
- or will receive ipilimumab and nivolumab given by intravenous infusion (directly into a vein) every 3 weeks at the study clinic 4 times. This will be followed by nivolumab given by intravenous infusion every 4 weeks at the study clinic.
Both pembrolizumab and nivolumab will be given for a maximum of around 2 years. However, there is no time limit for encorafenib and binimetinib treatment.
The study team will see how each participant is doing after receiving the study treatments during regular visits to the study clinic.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Melanoma | Drug: encorafenib Drug: binimetinib Drug: pembrolizumab Drug: ipilimumab Drug: nivolumab | Phase 2 |
The purpose of the study is to compare the efficacy of a triplet therapy (encorafenib, binimetinib, pembrolizumab) versus a doublet/control therapy (nivolumab and ipilimumab). Participants will have metastatic or unresectable locally advanced BRAF V600E/K-mutant melanoma, which progressed during or after prior treatment in the adjuvant or first-line metastatic setting, with an approved anti-PD-1 monotherapy (pembrolizumab or nivolumab),
Approximately 150 participants will be randomized in a 1:1 ratio to the triplet or the doublet/control therapy (75 participants in each arm). Randomization will be stratified by baseline serum LDH level, and by type of PD-1 resistance.

Primary Outcome Measures :
- Objective Response Rate (ORR) is defined as the proportion of participants in each treatment arm with a confirmed best overall response of either Complete Response (CR) or Partial Response (PR), as determined by investigator assessment per RECIST v1.1 [ Time Frame: Time from the date of randomization to the earliest date disease progression, or start of subsequent anticancer therapy, or death due to any cause (assessed up to approximately 48 months). ]
Secondary Outcome Measures :
- Progression Free Survival in each treatment arm [ Time Frame: Time from the date of randomization to the earliest date of disease progression, as determined by investigator assessment per RECIST v1.1, or death due to any cause, whichever occurs first (assessed up to approximately 48 months) ]
- Overall Survival in each treatment arm [ Time Frame: Time from date of randomization to the date of death due to any cause or the last known alive date (assessed up to approximately 48 months) ]
- Duration of Response (CR or PR) in each treatment arm [ Time Frame: Time from the date of the first documented response (CR or PR) to the earliest date of disease progression, as determined by investigator assessment per RECIST v1.1, or death due to any cause (assessed up to approximately 48 months) ]
- Disease Control Rate (proportion of participants with a confirmed best overall response of CR, PR or SD) in each treatment arm [ Time Frame: Time from the date of randomization to the earliest date of disease progression, or start of subsequent anticancer therapy (assessed up to approximately 48 months) ]
- Time to Response (CR or PR) [ Time Frame: Time from the date of randomization to the date of first documented response (CR or PR), as determined by investigator assessment per RECIST v1.1 (assessed up to approximately 48 months) ]
- Progression Free Survival 2 in each treatment arm [ Time Frame: Time from date of randomization to date of discontinuation of next-line treatment after 1st disease progression, 2nd disease progression after initiation of next line treatment, or death due to any cause (assessed up to approximately 48 months) ]
- Incidence and severity of Adverse Events (AEs) and changes in clinical laboratory parameters, vital signs, and cardiac assessments. [ Time Frame: Time from first dose of study intervention through 28 days after the last dose of study intervention ]Number of participants with treatment emergent Adverse Events as as assessed per National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE], version 4.03).
- Patient Reported Outcomes using EORTC QLQ-C30 questionnaires in each treatment arm [ Time Frame: Change from Baseline until Progressive Disease, death, withdrawal of consent, lost to follow-up, or end of study, whichever occurs first (assessed up to approximately 48 months) ]EORTC (European Organization for Research and Treatment of Cancer) QLQ-30 includes 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 scale
- Patient Reported Outcomes using EuroQOL EQ-5D-5L questionnaires in each treatment arm [ Time Frame: Change from Baseline until Progressive Disease, death, withdrawal of consent, lost to follow-up, or end of study, whichever occurs first (assessed up to approximately 48 months) ]The EQ-5D-5L is a standardized measure of health utility that provides a single index value of health status and contains 1 item for each of 5 dimensions of HRQoL (ie, mobility, self-care, usual activities, pain or discomfort, and anxiety or depression).
- BRAF V600E/K Variant Allele Frequency and/or overall mean Variant Allele Frequency from circulating tumour DNA analysis in each treatment arm [ Time Frame: Change from baseline, Day 1 of Cycle 2 (after 3 weeks), and End of Treatment (assessed up to approximately 48 months) ]
