Study to Compare Adjuvant Immunotherapy of Bempegaldesleukin Combined With Nivolumab Versus Nivolumab After Complete Resection of Melanoma in Patients at High Risk for Recurrence

Inclusion Criteria:

Male or female patients, age 12 years or older at the time of signing the informed consent form (age 18 years or older where local regulations, countries, and/or institutional policies do not allow for patients < 18 years of age (adolescents) to participate). In regions where adolescents are not allowed to participate in the study due to age restrictions, enrolled patients must be ≥ 18 years of age.
Histologically confirmed Stage IIIA (LN metastasis > 1 mm), IIIB/C/D, or IV (M1a/b/c/d) cutaneous melanoma by AJCC (8th edition) at study entry that has been completely surgically resected within 12 weeks prior to randomization.
Tumor tissue available from biopsy or resected disease must be provided to central laboratory for PD-L1 status analysis. Must have PD-L1 expression classification for stratification purposes.
Disease-free status documented by a complete physical examination and imaging studies within 28 days prior to randomization.

Exclusion Criteria:

History of ocular/uveal melanoma or mucosal melanoma.
Active, known or suspected autoimmune disease. Patients with Type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
Conditions requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of randomization. Inhaled or topical steroids, and adrenal replacement steroid doses > 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.
Prior therapy for melanoma except surgery for the melanoma lesion(s) and/or adjuvant radiation therapy for central nervous system lesions.
Prior therapy with interferon, talimogene laherparepvec (Imylgic®), interleukin-2 (IL-2) directed therapy, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-cytotoxic T lymphocyte-associated protein 4 antibody (including ipilimumab or any other antibody or drug specifically targeting T cell co-stimulation or checkpoint pathways).
Prior malignancy active within the previous 3 years except for locally potentially curable cancers that have been apparently cured.
