The Study of JS001 Compared to High-Dose Interferon In Patients With Mucosal Melanoma That Has Been Removed by Surgery

A Phase II Randomized, Control, Multi-center Study of Recombinant Humanized Anti-PD-1 mAb for Injection Compared to High-Dose Interferon In Patients With Mucosal Melanoma That Has Been Removed by Surgery

This is a phase II randomized, control, multi-center study of recombinant humanized anti-PD-1 mAb for injection compared to high-Dose interferon in patients with mucosal melanoma that has been removed by surgery.

This is a multi-centre，open, randomized, parallel-group study of mucosal melanoma adjuvant therapy to evaluate the efficacy of recombinant humanized anti-PD-1 mAb for injection compared to high-Dose interferon in patients with mucosal melanoma that has been removed by surgery.There will be 220 subjects enrolling the study, and randomized 1:1 grouped into recombinant humanized anti-PD-1 mAb for injection group (experimental group) or interferon group (control group).Each group will have 110 subjects.Random stratification factor is the disease stage (I vs II vs III).The whole research lasts about 60 months.

Inclusion Criteria:

• Male and Female aged between 18 and 75 years are eligible;

Exclusion Criteria:

• Prior treatment with anti-PD-1/PD-L1/PD-L2 antibody;
• Hypersensitivity to recombinant humanized anti-PD-1 monoclonal mAb or its components;
• Skin melanoma, ocular melanoma, original unknown melanoma;
• The primary lesion was incomplete;
• The examination suggests that the tumor remains or metastases;
• Pregnant or nursing;Women with fertility but not contraception;

• Participate in other clinical studies at the same time;
• Positive tests for HIV, HCV, HBsAg or HBcAb with positive test for HBV DNA (>500IU/ml);
• Patients with any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications, such as hypophysitis, pneumonia, colitis, hepatitis, nephritis, hyperthyroidism or hypothyroidism;
• Prior live vaccine therapy within past 4 weeks;
• Underlying medical condition that, in the Investigator's opinion, would increase the risks of study drug administration or obscure the interpretation of toxicity determination or adverse events
