Brief Summary

Innate immune cells are an important part of the body's innate immune system, the first line of defense against infection and cancer. Tumor killer cells (TKC) are mixed cultures of two kinds of innate immune cells, namely natural killer cells (NK cells) and gamma delta T cells (γδT cells), which are co-activated and co-cultured ex-vivo in a certain proportion by the unique TKC technology. Adoptive TKC transfer is expected to exert a strong anti-tumor effect through synergistic action between NK cells and γδT cells. In this study, the safety, tolerance, and preliminary efficacy of adoptive TKC transfer combined with chemotherapy will be examined in patients with advanced NSCLC.

Detailed Description

Primary Objective:

● To describe the safety profile and toxicity tolerance of combining adoptive TKC transfer with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC).

Secondary Objectives:

● To evaluate the preliminary efficacy of combining adoptive TKC transfer with chemotherapy in the treatment of advanced NSCLC.

Design:

• This is a single-centre, open label, non-randomised, no control clinical trial.
• NK cells and γδT cells are isolated from the patients' peripheral blood mononuclear cells (PBMCs) obtained before chemotherapy and then co-cultured with TKC technology ex-vivo. The mixed cultures will be used in multiple infusions under administration. The first infusion will be conducted in 7-10 days after chemotherapy and is assessed by the investigators.
• Clinical responses will be evaluated closely in about 30 days and last up to 2 years after treatment.

Study Groups

adoptive TKC transfer combined with chemotherapy

NK cells and γδT cells are isolated from the patients' PBMCs obtained before standard chemotherapy and then co-cultured ex-vivo. Patients will receive multiple TKC treatments under administration, 3 weeks/cycle. The first infusion will be conducted in 7-10 days after chemotherapy and is assessed by the investigators. TKC cells are transfused to patients in a dosage escalated manner. Dose escalation starts at 1×10\^8 cells/kg (based on the whole body weight). After the safety assurance of the initial administration, the next course, up to 8 courses, is resumed and the dose maybe increased subsequently at the discretion of the investigators, or reduced for safety reason.
