Diagnosis of melanoma of unknown primary at the discretion of the treating oncologist and sponsor c.Cohort 3: Patients with stage IV or unresectable cutaneous melanoma, acral or mucosal melanoma already receiving standard-of-care ICI (either single-agent anti-PD-1 or combination anti-CTLA-4 plus anti-PD-1) at the first sign of progression i.Patients with melanoma of unknown primary are permitted to enroll.

7. In the last year, has a known history of a malignancy requiring anti-neoplastic treatment.

   a. NOTE: This time requirement does not apply to patients who underwent successful definitive resection of basal or squamous cell carcinoma of the skin, superficial bladder cancer, in situ cancers including cervical cancer, breast cancer, melanoma, or other in situ cancers;

8. Symptomatic central nervous system (CNS) metastases
9. Leptomeningeal involvement (leptomeningeal enhancement on MRI/CT imaging and/or positive CSF cytology);

    a. Patients with vitiligo, type I diabetes, well controlled hypothyroidism due to Hashimoto disease, resolved childhood asthma/atopy are permitted to enroll.

11. A history of (non-infectious) pneumonitis that required steroids or current pneumonitis.
12. Has serious concomitant illnesses, such as: impaired cardiovascular function or clinically significant cardiovascular disease (uncontrolled congestive heart failure requiring treatment (NYHA grade > 3), uncontrolled hypertension, acute myocardial cardiac ischemia or unstable angina < 2 months prior to study entry, and severe cardiac arrhythmia), active inflammatory bowel disorders.
13. Active kidney disease/severe chronic kidney or liver disease or hematological blood test alteration that would preclude safe administration of chemotherapy at the discretion of the sponsor.
