1. Age = 18 years
2. Written informed consent must be obtained from all patients prior to any study procedures.
3. Patients with advanced non-uveal melanoma defined as unresectable
Stage III or metastatic Stage IV disease. Patients with acral or mucosal melanoma are acceptable. Patients with melanoma of unknown primary source are acceptable for Phase Ib cohorts (Arms 1 to 4), but are excluded in Phase II cohorts. Patients with the diagnosis of uveal melanoma are excluded from all cohorts.
4.Phase Ib Arm 4 and Phase II: Patients with disease progression
following initiation of treatment with an approved PD-1 inhibitor. No
prior cytotoxic therapy in the advanced setting is permitted. Patients
with BRAF mutations must be refractory to approved BRAF-based
therapy. CTLA-4-inhibition therapy is acceptable as a prior line of
therapy or in combination with anti-PD-1 therapy
5. Note: intentionally left blank by Sponsor in order to align with Protocol revision.
6. Phase Ib Arms 1, 2 and 3: no restriction on prior therapy.
7. Human leukocyte antigen-A*0201 (HLA- A*0201) positive
8. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
9. Life expectancy of at least 3 months
10. Phase II cohorts only: patients must have measurable disease according to RECIST v.1.1 criteria. Patients enrolled in Phase Ib cohorts must have evaluable disease
11. Phase Ib Arm 4 and Phase II cohorts only: Patients must have a site
of disease amenable to biopsy that is not an index lesion, and be a
candidate for tumor biopsy according to the treating institution's
guidelines. Phase Ib Arms 1-3 patients need not have disease accessible
to biopsy
12. Those receiving prior immunotherapy must meet all of the following conditions:
-Must not have experienced an immune-related adverse event (irAE) which was the reason for permanent discontinuation of prior immunotherapy in the most recent prior treatment regimen
- All irAEs while receiving prior immunotherapy must have resolved to = grade 1 or Baseline prior to Screening for this study. Must not have experienced a = grade 3 immune-related AE within the past 16 weeks or any grade 4 life-threatening AE (regardless of duration) or neurologic or ocular AE of any grade while receiving prior immunotherapy. (NOTE: Patients with endocrine AE of any grade are permitted to enroll if they are stably maintained on appropriate replacement therapy, but must have no history of adrenal crisis and be asymptomatic)
- Patients currently receiving chronic corticosteroid treatment (longer than 8 weeks duration) for management of pre-existing adverse events, or patients with a history of chronic corticosteroid treatment longer than 8 weeks’ duration for adverse events within 6 months of Screening are excluded

1. Presence of untreated or symptomatic central nervous system metastases, or central nervous system metastases that currently require local therapy (such as radiotherapy or surgery), or require doses of corticosteroids within the prior 4 weeks.
2. History of severe hypersensitivity reactions to other monoclonal antibodies (mAb)s.
3. History of treatment-related interstitial lung disease/pneumonitis.
4. Patient with any out of range laboratory values.
• Serum creatinine > 1.5 x ULN and/or creatinine clearance (calculated using Cockcroft-Gault formula, or measured) < 50 mL/min
• Total bilirubin > 1.5 x upper limit of normal (ULN), except for patients with Gilbert’s syndrome who are excluded if total bilirubin > 3.0 x ULN or direct bilirubin > 1.5 x ULN
• Alanine aminotransferase (ALT) > 3 x ULN
• Aspartate aminotransferase (AST) > 3 x ULN
• Absolute neutrophil count (ANC) < 1.0 x 109/L
• Absolute lymphocyte count < 0.5 x 109/L
• Platelet count < 75 x 109/L
• Hemoglobin (Hgb) < 8 g/dL
• Potassium, magnesium, corrected calcium or phosphate abnormality of National Cancer Institute Common Terminology Criteria for Adverse Events, (CTCAE) > grade 1
5. Clinically significant cardiac disease or impaired cardiac function.
• Clinically significant and/or uncontrolled heart disease such as congestive heart failure (New York Heart Association NYHA grade = 2), uncontrolled hypertension or clinically significant arrhythmia currently requiring medical treatment
• QTcF >470 msec on screening electrocardiogram (ECG) or congenital long QT syndrome
• Acute myocardial infarction or unstable angina pectoris < 6 months prior to Screening
6. Active autoimmune disease or a documented history of autoimmune disease within 3 years before Screening (or as indicated below), including the following:
• A documented history of inflammatory bowel disease (ulcerative colitis or Crohn’s disease, within 3 years)
• Patients with vitiligo, alopecia, managed hypothyroidism (on stable replacement doses), psoriasis, resolved childhood asthma/atopy, well-controlled asthma and type I diabetes mellitus are NOT excluded
7. Recent (< 12 months) active diverticulitis (PhIb combination arms
and PhII only)
8. Active infection requiring systemic antibiotic therapy. Patients requiring systemic antibiotics for infection must have completed therapy before Screening is initiated.
9. Known history of human immunodeficiency virus (HIV) infection.
10. Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, currently requiring medical intervention, per institutional protocol.
11. Malignant disease, other than that being treated in this study.
12. Any medical condition that would, in the investigator’s judgment, prevent the patient’s participation in the clinical study due to safety concerns, compliance with clinical study procedures or interpretation of study results.
13. Systemic anti-cancer therapy within 2 weeks of the first dose of study treatment. For cytotoxic agents that have major delayed toxicity and any prior immunotherapy approach, 4 weeks is indicated as washout period.
14. Presence of NCI CTCAE = grade 2 toxicity (except alopecia, peripheral neuropathy and ototoxicity, which are excluded if = NCI CTCAE grade 3) due to prior cancer therapy.
15. Chronic, systemic corticosteroid use
