About this study

Official title: A PHASE 2, RANDOMIZED, OPEN-LABEL STUDY OF ENCORAFENIB AND BINIMETINIB PLUS PEMBROLIZUMAB VERSUS NIVOLUMAB AND IPILIMUMAB IN PARTICIPANTS WITH BRAF V600E/K MUTATION-POSITIVE MELANOMA WHO PROGRESSED DURING OR AFTER PRIOR TREATMENT WITH ANTI-PD-1 THERAPY

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.

Read more

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.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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

    Measured: 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 outcomes (10)
  1. Progression Free Survival in each treatment arm

    Measured: 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)

  2. Overall Survival in each treatment arm

    Measured: 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)

  3. Duration of Response (CR or PR) in each treatment arm

    Measured: 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)

  4. Disease Control Rate (proportion of participants with a confirmed best overall response of CR, PR or SD) in each treatment arm

    Measured: 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)

  5. Time to Response (CR or PR)

    Measured: 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)

  6. Progression Free Survival 2 in each treatment arm

    Measured: 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)

  7. Incidence and severity of Adverse Events (AEs) and changes in clinical laboratory parameters, vital signs, and cardiac assessments.

    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).

    Measured: Time from first dose of study intervention through 28 days after the last dose of study intervention

  8. Patient Reported Outcomes using EORTC QLQ-C30 questionnaires in each treatment arm

    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

    Measured: 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)

  9. Patient Reported Outcomes using EuroQOL EQ-5D-5L questionnaires in each treatment arm

    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).

    Measured: 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)

  10. BRAF V600E/K Variant Allele Frequency and/or overall mean Variant Allele Frequency from circulating tumour DNA analysis in each treatment arm

    Measured: Change from baseline, Day 1 of Cycle 2 (after 3 weeks), and End of Treatment (assessed up to approximately 48 months)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing encorafenib, binimetinib and pembrolizumab in people with Melanoma, run by Pfizer at 24 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 9 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Italy, Spain, Germany, Slovakia, Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Study terminated due to inability to recruit the target number of patients. There were no safety and/or efficacy concerns involved in the decision to stop enrollment.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?
