The purpose of this study is to assess the safety and effectiveness of natural killer T (NKT) cell-based autologous adoptive immunotherapy in subjects with metastatic, treatment-refractory breast cancer, glioma, hepatocellular carcinoma, squamous cell lung cancer, pancreatic cancer, colon cancer or prostate cancer.

A randomized controlled trial on the efficacy and safety of autologous natural killer T (NKT) cells infusion treatment in advanced cancer.
