A Study Comparing 3 Study Medicines (Encorafenib, Binimetinib, Pembrolizumab) to 2 Study Medicines (Ipilimumab and Nivolumab) in Patients With Advanced Melanoma

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

- Prior or current symptomatic brain metastasis, leptomeningeal disease or other active CNS metastases.

- Participants who permanently discontinued prior anti-PD-1 therapy due to toxicity or will be unable to tolerate combination therapy based on investigator judgement are excluded.

- Prior treatment with ipilimumab; prior combined immunotherapy blockade with anti-PD-1/L-1; prior treatment with a BRAFi and/or MEKi; or previous administration of an investigational anti-cancer agent for the adjuvant or first-line treatment of melanoma prior to randomization.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05926960
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 2

Additional Details

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.
