About this trial
Melanoma has emerged as the fastest-growing malignancy in recent years, with incidence and mortality rates among both men and women in East Asian countries exceeding the Asian average. China ranks fifth among East Asian nations in melanoma incidence. Currently, immune checkpoint inhibitors are achieving significant breakthroughs in adjuvant melanoma therapy. This study aims to evaluate the efficacy and safety of sintilimab combined with chemotherapy versus chemotherapy alone in patients with PD-L1-positive, completely resectable mucosal melanoma, thereby providing additional clinical evidence for treatment decisions.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Sign a written informed consent form (Informed Consent, ICF) and be able to comply with the visit schedule and related procedures outlined in the protocol.
Histologically/cytologically confirmed mucosal melanoma, with primary and/or metastatic lesions completely resected, with negative surgical margins.
Tissue specimen: PD-L1 positive (CPS ≥ 1).
The first dose of the study drug must be administered only after the melanoma resection wound has fully healed, and the injection time must not exceed 13 weeks post-surgery (if the time limit is exceeded by no more than 7 days due to unforeseen circumstances, the decision to enroll may be discussed with the medical monitor).
Disqualifiers
Previous exposure to any anti-PD-1 or anti-PD-L1/2 antibody.
Previous use of interferon.
Hyperthyroidism or hypothyroidism. Note: Hypothyroid patients whose condition is stable after hormone replacement therapy may be included.
Concurrent participation in another clinical trial.

Overall Survival
Time from randomization to documented death from any cause.
Number of participants with treatment-emergent adverse events (TEAEs) as assessed by CTCAE v5.0.
