Toripalimab in the Neoadjuvant Treatment of BRAF V600 Wild Type Melanoma

Study Purpose

In view of the fact that neoadjuvant therapy for malignant melanoma is in the exploratory stage, and the current data on neoadjuvant immunology are mainly from European and American populations, it is necessary to carry out clinical trials in the status of neoadjuvant immunotherapy for patients with melanoma in China. Toripalimab has been extensively studied in the field of malignant melanoma, and its effectiveness and safety have been proven. Therefore, the investigators initiated a single-arm exploratory study to investigate the efficacy and safety of Toripalimab in neoadjuvant treatment of patients with BRAF V600 wild-type malignant melanoma.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.
