Safety and Effectiveness Study of Autologous Natural Killer and Natural Killer T Cells on Cancer
A Phase I Open Label, Single Site, Safety and Efficacy Study of the Effects of Autologous Natural Killer and Natural Killer T Cell Immunotherapy on Malignant Disease
The purpose of this study is to assess the safety and effectiveness of natural killer (NK) cell and 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.
Not Provided
Phase 1
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Breast Cancer
  • Glioma
  • Hepatocellular Cancer
  • Squamous Cell Lung Cancer
  • Pancreatic Cancer
  • Colon Cancer
  • Prostate Cancer
Biological: Autologous Natural Killer / Natural Killer T Cell Immunotherapy

The study drug is derived from ex vivo expansion of each subject's own white blood cells and is therefore autologous.

The current study proposes a 3-course treatment of doses administered at one week intervals with monitoring at each administration plus 2 weeks after the last dose. The total study time (apheresis through last follow-up) is estimated at 15 weeks.
