A Phase 3, Randomized, Open-label Study of Adjuvant Immunotherapy with'Bempegaldesleukin Combined with Nivolumab Versus Nivolumab After Complete Resection of Melanoma in Participants at High ·sk for Recurrence (PIVOT-12)

The main purpose of this study is to compare the efficacy of bempegaldesleukin plus nivolumab versus nivolumab in patients with completely resected Stage IIIA/B/C/D, or Stage IV cutaneous melanoma who are at high risk for recurrence.

Inclusion Criteria:
• 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 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 curable cancers that have been apparently cured.
