Inclusion Criteria

- Male or female must be = 18 years
- body weight > 40kg
- Histologically confirmed unresectable or metastatic cutaneous melanoma
- Previously treated for unresectable or metastatic melanoma:Participants with NRAS mutation:
Participants must have received prior systemic therapy for unresectable or metastatic melanoma with checkpoint inhibitors ( CPI) either an anti-PD-1/PD-L1 as a single agent or in combination with anti-CTLA-4. investigational agents, chemotherapy or locally directed antineoplastic agents
- Prior checkpoint inhibitor therapy in the unresectable or metastatic setting is not required for participants who have progressed on or within 6 months of adjuvant therapy with a checkpoint inhibitor
- Prior therapy with T-VEC (talimogene laherparepvec) is allowed and will not be counted as a prior line of systematic therapy
- A maximum of two prior lines of systemic CPI-containing immunotherapy for unresectable or metastatic melanoma are allowed
- Additional agents administered with a CPI are permitted
- To rule out pseudo-progression, participants must have documented confirmed progressive disease as per RECIST v1.1 while on/after
treatment with checkpoint inhibitor therapy. Confirmation is not required for patients who remained on treatment >6 months.
Participants with BRAFV600 mutant disease:
- Participants must have received prior systemic therapy for unresectable or metastatic melanoma with a checkpoint inhibitor (CPI),
either an anti-PD-1/anti-PD-L1 as a single agent or in combination with anti-CTLA-4, investigational agents, chemotherapy or locally directed anti-neoplastic agents. Additionally, participants must have received targeted therapy with a RAFi as a single agent or in combination with a MEKi (+/- CPI allowed) as the last prior therapy
- Prior checkpoint inhibitor therapy in the unresectable or metastatic setting is not required for participants who have progressed on or within 6 months of adjuvant checkpoint inhibitors
- Prior therapy with T-VEC (talimogene laherparepvec) is allowed and will not be counted as a prior line of systematic therapy
- A maximum of two prior lines of CPI-containing systemic immunotherapy for unresectable or metastatic melanoma are allowed. Additional agents with CPI are permitted
- A maximum of one line of targeted therapy is allowed, and it must be the most recent line of therapy
- If a participant discontinued targeted therapy for reasons other than disease progression, a switch to another targeted therapy regimen is allowed
- Participants must have documented confirmed progressive disease as per RECIST v1.1 while on/after treatment with checkpoint inhibitor therapy. The last progression must have occurred within 12 weeks prior to randomization in the study
- Participants with BRAFV600 mutant disease:
- Participants must have received prior systemic therapy for unresectable or metastatic melanoma with anti-PD-1/PD-L1 as a single agent or in combination with anti-CTLA-4. Additionally, participants must have received targeted therapy with a RAFi as a single agent or in combination with a MEKi as the last prior therapy. No additional systemic treatment is allowed for advanced or metastatic melanoma
- A maximum of three prior lines of systemic therapy for unresectable or metastatic melanoma are allowed
- The last dose of targeted therapy (last prior therapy) must have been received more than 2 weeks prior to randomization
- Participants must have documented progressive disease as per RE

Exclusion Criteria

Treatment with any of the following anti-cancer therapies prior to the first dose of study treatment within the stated timeframes:
= 4 weeks for radiation therapy or = 2 weeks for limited field radiation for palliation prior to the first dose of study treatment.
= 2 weeks for small molecule therapeutics.
= 4 weeks for any immunotherapy treatment including immune checkpoint inhibitors.
• = 4 weeks for chemotherapy agents, locally directed antineoplastic agents, or other investigational agents.
• = 6 weeks for cytotoxic agents with major delayed toxicities, such as nitrosourea and mitomycin c.
- Participants participating in additional parallel investigational drug or medical device studies.
- All primary central nervous system (CNS) tumors or symptomatic CNS metastases that are neurologically unstable
- History or current evidence of retinal vein occlusion (RVO) or current
risk factors for RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyperviscosity or hypercoagulability syndromes).
- Patients receiving proton pump inhibitors (PPI) which cannot be discontinued 3 days prior to the start study treatment and for the duration of the study.
Any medical condition that would, in the investigator's judgment,prevent the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures.
-Other protocol-defined inclusion/exclusion criteria may apply
