Melanoma (Excluding Uveal Melanoma)

This is a multicenter, randomized controlled, open-label Phase II clinical study designed to evaluate the efficacy and safety of HS-IT101 Injection versus the investigator's choice of chemotherapy in participants with advanced melanoma. A total of 90 participants are planned to be enrolled, and eligible participants will be randomly assigned to the experimental group or control group at a 1:1 ratio. The experimental group will receive a single administration of autologous tumor-infiltrating lymphocyte therapy, while the control group will receive chemotherapy regimens selected by the research physicians. Efficacy and safety evaluations will be conducted for all enrolled participants throughout the study.
