Induced-T Cell Like NK Cellular Immunotherapy for Cancer Lack of MHC-I

Overview

T effector cells and NK cells have mutual compensatory killing functions on various of cancer types. For those cancers that have no available targets for CAR-T cell generations, we established potent T cell-like NK cells (ITNK) with a specific conversion protocol for the T cells from the patient, to perform anti-cancer therapy, especially for those cancers that are lack of MHC-I molecule expression. We have finished pre-clinical investigations for the ITNK cell therapy and scheduled to start a clinical phase I study.

Description

One gene can be knockout of the T cells to produce a T-like NK cells which obtain killing function of both T effector cells and NK cells. We will collect appropriate patient's T cells, produce T-like NK cells (ITNK), and infuse the ITNK cells back to the patients to treat various of cancers.
