Study of autologous immune cell therapy in combination with the luteinizing hormone releasing hormone agonists (LHRH-a) in patients with metastatic castration-resistant prostate cancer

Autologous dendritic cells (DC) are known to activate other immune cells, such as central memory T cells (Tcm cells), that are able to mount an attack against cancer cells. The purpose of this study is to evaluate the feasibility, safety and efficacy of patients' own immune cells combined with the luteinizing hormone releasing hormone agonists (LHRH-a) for treatment of metastatic castration-resistant prostate cancer.

Inclusion Criteria:

• Males age ≥ 18 years；
• Subjects who understand and sign the consent form for this study；
