- RFS of bempegaldesleukin plus nivolumab versus nivolumab alone by BICR, is defined as the time between date of randomization and date of first recurrence, new primary melanoma, or all-cause death [ Time Frame: Approximately up to 60 months ]
- Overall Survival (OS) defined as the time between the date of randomization and the date of death due to any cause [ Time Frame: Approximately up to 83 months ]
- Distant metastasis-free survival (DMFS) by BICR and by Investigator in patients who have Stage IIIA (LN metastasis > 1 mm) or IIIB/C/D melanoma at study entry. [ Time Frame: Approximately up to 60 months ]To evaluate distant metastasis-free survival (DMFS) by BICR and by Investigator in patients who have Stage IIIA (LN metastasis > 1 mm) or IIIB/C/D melanoma at study entry. Distant Metastasis Free Survival is defined as the time between the date of randomization and the date of first distant metastasis or date of death due to any cause.
- Overall safety and tolerability of bempegaldesleukin plus nivolumab will be measured by the incidence of AEs, SAEs, deaths, and laboratory abnormalities using CTCAE Version 5.0 criteria [ Time Frame: Approximately up to 60 months ]
- Patient Reported Outcomes will be measured by changes from baseline in scores for the global health/quality of life and physical functioning subscales of the European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire [ Time Frame: Approximately up to 60 months ]
- The predictive strength of PD-L1 expression as a biomarker will be measured by the endpoint RFS by BICR based on PD-L1 expression level [ Time Frame: Approximately up to 60 months ]
- RFS by Investigator will be measured similarly to the primary endpoint, but recurrence and new primary melanoma will be decided by the Investigator [ Time Frame: Approximately up to 60 months ]
- Time to disease progression after the next line of treatment for study patients following discontinuation of bempegaldesleukin plus nivolumab versus nivolumab [ Time Frame: Approximately up to 60 months ]To evaluate time to disease progression after the next line of treatment for study patients following discontinuation of bempegaldesleukin plus nivolumab versus nivolumab

Ages Eligible for Study: | 12 Years and older (Child, Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
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.
