156UV1 is a therapeutic cancer vaccine that has been explored in prostate, lung cancer, in combination with ipilimumab in malignant melanoma and in combination with pembrolizumab in metastatic melanoma. This study will explore the Efficacy and Safety of UV1 administered with GM-CSF in combination with nivolumab and ipilimumab.
This is a randomized, open label study to investigate efficacy and safety of UV1 vaccination in combination with nivolumab and ipilimumab as first line treatment of adult patients with histologically confirmed unresectable metastatic melanoma.
Patients in the experimental arm will receive 8 UV1 vaccinations over 4 cycles of nivolumab and ipilimumab. Patients in the control arm will receive 4 cycles of nivolumab and ipilimumab. Patients in both arms will start maintenance therapy 6 weeks after the last dose of induction therapy, nivolumab at a dose of 480 mg every 4 weeks.
All patients will be followed up until death or until the end of the study.
To support the Extended Exploratory Cohort of the study, an additional 20 patients at selected sites will be enrolled in a single arm UV1 cohort for collection of additional biological material. These patients are in addition to the 156 randomized patients in the main part of the study.
UV1 vaccine (300 μg) will be injected intradermally.

Women of childbearing potential (WOCBP) must have a negative urine or serum/plasma pregnancy test. WOCBP must use adequate contraception. Exclusion Criteria: Previous non melanoma malignancies unless curatively treated and complete remission was achieved at least 2 years prior to randomization. Patients with prior curatively treated basal or squamous cell carcinoma of the skin, carcinoma in situ of the cervix, or carcinoma in situ of the breast, or other in situ cancers are allowed irrespective of time passed since curative treatment. Patients with prior completely resected malignant melanoma are also allowed. Known brain metastases or leptomeningeal metastases.

Known history or any evidence of active, non-infectious pneumonitis. History of New York Heart Association class 3-4 congestive heart failure or history of myocardial infarction within 6 months of starting induction therapy. Active infection requiring systemic treatment. Diagnosis of immunodeficiency. Known history of severe hypersensitivity reactions to nivolumab, ipilimumab, sargramostim, or their excipients. Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies). History of or active hepatitis B (hepatitis B surface antigen reactive) or active hepatitis C (hepatitis C virus antibody). Women who are breastfeeding. Prior systemic treatment for unresectable stage IIIB D or unresectable stage IV malignant melanoma. Systemic corticosteroid treatment (doses exceeding 10 mg daily of prednisone or equivalent) or any other form of immunosuppressive treatment within 7 days prior to the first dose of induction therapy. Receipt of a live vaccine within 30 days prior to start of induction therapy. Receipt of any other investigational treatment within 4 weeks of the first dose of induction therapy.
