Clinical Trial Summary

This is a randomized, controlled, multicenter Phase II clinical study to evaluate the efficacy and safety of toripalimab injection combined with axitinib in the first-line treatment of patients with advanced mucosal melanoma. The target population is the patients with previously untreated, histopathologically confirmed, unresectable or metastatic mucosal melanoma. At the randomization, patients are randomized 1:1:1 into three groups with approximately 33 subjects in each group to receive toripalimab injection plus axitinib, toripalimab injection monotherapy (subjects who meet the criteria after disease progression may cross over to receive toripalimab plus axitinib), or axitinib monotherapy (subjects who meet the criteria after disease progression may cross over to receive toripalimab plus axitinib); when the patient has disease progression or intolerable toxicity, the treatment is terminated, and the survival follow-up will be initiated.

3. Major surgery, live vaccination, immunotherapy within 4 weeks prior to study start, and radiotherapy within 2 weeks prior to study start.

4. History of malignancy other than mucosal melanoma within the past 3 years, with the exception of cured basal cell carcinoma of the skin, squamous cell carcinoma of the skin, early stage prostate cancer, and carcinoma in situ of the cervix.

5. Patients who received hematopoietic stimulating factors, such as granulocyte colony-stimulating factor (G-CSF) and erythropoietin, within 1 week prior to study start.

6. HIV test positive.

7. Patients with active hepatitis B or C:

• If HBsAg or HBcAb is positive, additionally test HBV DNA (results above the lower limit of detection at site);

• If the result of HCV antibody test is positive, additionally test HCV RNA.

8. Known to be allergic to recombinant humanized PD-1 monoclonal antibody drug and its components; known to be allergic to axitinib and any of its excipients.

9. Hypertension that cannot be controlled by medication.

10. Massive pleural effusion or ascites with clinical symptoms requiring symptomatic management.

11. Subjects with active central nervous system (CNS) metastases are excluded. Subjects with metastatic brain lesions are eligible if they have received treatment and have no evidence of disease progression on magnetic resonance imaging (MRI) at least 8 weeks after completion of treatment and within 28 days before the first dose. Immunosuppressive doses of systemic corticosteroids (>10 mg/day prednisone equivalent) must not be required at least 2 weeks prior to study drug administration.

12. History of active pulmonary tuberculosis.

13. Have any uncontrollable clinical problems, including but not limited to:

• Active autoimmune disease requiring systemic steroid/immunosuppressive therapy, such as hypophysitis, colitis, hepatitis, nephritis, etc.;

• Have the following occurrence within 6 months prior to randomization: 1) deep vein thrombosis or pulmonary embolism; 2) percutaneous coronary intervention, acute coronary syndrome, coronary artery bypass grafting; 3) cerebrovascular accident, transient ischemic attack.

• Other serious, uncontrollable concomitant illness that may affect protocol compliance or interfere with interpretation of results, including active opportunistic infection or progressive (severe) infection, uncontrolled diabetes, cardiovascular disease (New York Heart Association class III or IV heart failure, second degree or higher heart block, myocardial infarction within the past 6 months, unstable arrhythmia or unstable angina, cerebral infarction within 3 months, etc.) or pulmonary disease (history of interstitial pneumonia, obstructive pulmonary disease, and symptomatic bronchospasm).

14. Any condition that affects the subject's swallowing of the drug, and any condition that affects the absorption or pharmacokinetics of the investigational product.

15. Have received stem cell transplant or organ transplant.

16. Women of childbearing age, pregnant or lactating women with positive serum or urine pregnancy test 7 days before starting treatment.

17. Have a history of psychotropic drug abuse and unable to withdraw or have a history of mental disorders.

18. Other severe, acute, or chronic medical conditions or laboratory abnormalities that, in the judgment of the investigator, may increase the risk associated with study participation or may interfere with the interpretation of study results.

19. Patients who are judged by the investigator to have poor compliance, or other conditions that make them unsuitable for this trial.

Secondary	INV-ORR	INV-ORR in crossover subjects is the number of subjects with DOR of CR or PR based on INV assessment divided by the number of crossover subjects. DOR is defined as the best response recorded as measured by INV from the date of the first crossover dose to the date of objective documentation of progression per RECIST 1.1 or the date of subsequent therapy, including tumor-directed radiotherapy and tumor-directed surgery, whichever occurs first. For subjects without documented progression or subsequent treatment, all available response designations will be assigned to the DOR evaluation. Baseline tumor assessments for crossover subjects are based on the last tumor assessment for monotherapy prior to the combination crossover. Exploratory endpoints will be analyzed at the time of primary endpoint analysis if data are available.	36 months
