Study of Oncolytic Virus in Combination With HX-008 and Axitinib in Melanoma Patients With Liver Metastasis

Study Purpose

Malignant melanoma, is a kind of malignant tumor derived from melanocytes. It is common in skin, mucous membrane, eye choroid and other parts. Melanoma is one of the fastest growing malignant tumors with an annual incidence rate of 3-5%. In 2012, there were 232000 new cases of melanoma and 55000 deaths worldwide. Though, the incidence rate of melanoma is relatively low in China, it has been increasing rapidly in recent years. Melanoma has seriously endangering the health of Chinese people. Patients with stage Ⅳ melanoma have a poor prognosis. According to statistics, the median survival time of stage M1a melanoma is 15 months, while stage M1b is 8 months. The median survival time of bone metastasis melanoma is 6 months, while liver and brain metastasis is 4 months. The overall median survival time of metastatic melanoma is only 7.5 months, and the 2-year survival rate is 15%. For patients with advanced melanoma, dacarbazine is the only chemotherapy drug approved by NMPA, but its overall effective rate is only 13.4%, and the median survival time is 5.6 ~ 11 months. Therapies(new drugs or new combination treatments)with higher remission rate and longer survival are urgently needed for patients with advanced melanoma.

Recruitment Criteria
