Description

Inclusion Criteria:

1. Sign the written informed consent (Informed Consent, ICF), and be able to abide by the visits and related procedures stipulated in the plan.
2. Completely resected stage IIIB-IV acral melanoma (according to the 8th edition of AJCC staging criteria for malignant melanoma of the skin). Complete resection of stage III melanoma includes extended resection of the primary lesion and/or regional lymph node dissection and/or resection of satellite nodules. Complete resection of stage IV melanoma includes resection of primary tumor and complete resection of metastases. Complete resection of melanoma should conform to the principle of R0 resection and be confirmed by the investigator. Requirements for regional lymph node dissection refer to: upper extremity melanoma, at least 10 lymph nodes in the draining lymph node area; lower extremity melanoma, at least 5 lymph nodes in the draining lymph node area. In special cases, such as ① the long diameter of lymph nodes is ≥ 3 cm, it is considered that the number of lymph nodes can not be resected because of lymph node fusion; ② the draining lymph node area that needs to be cleaned only includes the cubital fossa or popliteal fossa, and the number of lymph nodes is difficult to reach 5-10, etc., it needs to be studied The patient confirmed whether the lymph node dissection was in line with R0 resection.
3. Stage IIIB-IV acral melanoma with histologically/cytologically confirmed primary lesions in extremities (hands, feet, subungual nails). For subjects with only metastatic lesions confirmed by histopathology, researchers need to confirm that the primary lesions are in the extremities and exclude other primary sites, and they can discuss with the medical monitors to decide whether to enroll.
4. The first study drug injection can only be carried out when the incision is completely healed after melanoma resection, and the injection time should not exceed 13 weeks after the operation (if the time limit is exceeded due to unforeseen reasons, it can be discussed with the medical supervisor decision to enroll).
5. Within 4 weeks before randomization, R0 complete resection was confirmed by physical examination and imaging examination.

Exclusion Criteria：

1. Mucosal-derived melanoma, ocular uveal melanoma, transitional metastasis and leptomeningeal metastasis.
2. Previously exposed to any anti-CTLA-4, anti-PD-1 or anti-PD-L1/2 antibodies.
3. Previous use of interferon. If interferon therapy was used ≥ 1 year before the first dose of study treatment, and the treatment time was ≤ 30 days or the treatment dose was ≤ 3×106IU/d, they could be enrolled.
4. Hyperthyroidism or hypothyroidism, Note: Hypothyroidism subjects with stable condition after hormone replacement therapy can be enrolled.
5. Participate in another clinical study at the same time.
