Clinical Efficacy and Safety of NK and NKT Cells Infusion in Patients With Non Small Cell Lung Cancer

Phase 1

• Conditions: Non-small Cell Lung Cancer
• Interventions: Biological: natural killer and natural killer T cell

• Registration Number: NCT03198923
• Lead Sponsor: Wenxiang Wang

Brief Summary

The purpose of this study is to assess the safety and effectiveness of natural killer (NK) cell and natural killer T (NKT) cell-based immunotherapy in subjects with non small cell lung cancer.

Detailed Description

With the development of oncology and immunology in recent years, immunotherapy represents a novel path to obtain a durable and long-lasting response in cancer patients. NK and NKT cells are expanded conventionally from peripheral blood mononuclear cells by addition of a variety of cytokines in vitro culture. Our previous studies demonstrated that the expansion of NK and NKT cells in a clinical usage scale from peripheral blood mononuclear cells is feasible. Those expanded NK and NKT cells exhibit antitumor effect in vitro and in vivo against a variety of tumor cells. The current study proposes a 3-course treatment of doses administered at one week intervals with monitoring at each administration plus 4 weeks after the last dose. The total study time (apheresis through last follow-up) is estimated at 3 year.
