Participants that do not have a BRAF V600 mutation but did receive BRAF or BRAF/MEKi therapy are eligible to participate in this study after discussion with the medical monitor.
b. Prior adjuvant or neoadjuvant therapy, with targeted therapy or immunotherapy (such as anti-cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], anti-programmed cell death 1 [anti-PD-1] therapy or interferon) will only be permitted if relapse did not occur during active treatment or within 6 months of treatment discontinuation.

- Has urine protein ≥1 g/24-hour. Note: Participants with ≥2+ (≥100 mg/dL) proteinuria on urine dipstick testing (or urinalysis) will undergo 24-hour urine collection for quantitative assessment of proteinuria.
- Prolongation of QTcF interval to >480 ms. Note: If the QTcF is prolonged to >480 ms in the presence of a pacemaker, contact the Sponsor to determine eligibility.
- Has left ventricular ejection fraction (LVEF) below the institutional (or local laboratory) normal range, as determined by multigated acquisition scan (MUGA) or echocardiogram.
- Has received prior therapy in the adjuvant setting. Note: Targeted therapy, anti-CTLA-4, or anti-PD-1 may be allowed.
- Has received prior systemic treatment for unresectable or metastatic melanoma other than targeted therapy as noted in Inclusion Criteria above.
- Has received prior therapy with a monoclonal antibody, chemotherapy, or an investigational agent or device within 4 weeks or 5 half-lives (whichever is longer) before administration of study treatment or not recovered (≤Grade 1 or at Baseline) from adverse events due to previously administered agents.
Exception to this rule would be use of denosumab, which is not excluded. Note: Participants with alopecia and ≤Grade 2 neuropathy are an exception and may enroll.
- Has received prior radiotherapy within 2 weeks of first dose of study treatment (Cycle 1 Day 1). Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis.
- Has received live vaccine within 30 days before the first dose of study treatment.
- Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the treating investigator.
- Has had an allogeneic tissue/solid organ transplant.
- Has a known psychiatric or substance abuse disorder that would interfere with cooperation with the requirements of the study.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Progression-free Survival (PFS) as Assessed by Modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame: Up to approximately 36 months
|
PFS is defined as the time from date of randomization to the date of the first documentation of progressive disease (PD) or death from any cause, whichever occurs first.
Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions.
In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm.
Note: The appearance of one or more new lesions is also considered PD.
For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
PFS as assessed by modified RECIST 1.1 will be presented.
|
Up to approximately 36 months
|
Overall Survival (OS)
Time Frame: Up to approximately 36 months
|
OS is defined as the time from date of randomization to date of death from any cause.
OS will be presented.

|
ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1.
For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.

Duration of Response (DOR) as Assessed by Modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame: Up to approximately 36 months
|
For participants who demonstrated CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions), DOR is defined as the date of the first documented evidence of CR or PR until PD or death from any cause, whichever occurs first.
Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions.
In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm.
Note: The appearance of one or more new lesions is also considered PD.
For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
DOR as assessed by modified RECIST 1.1 will be presented.
