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.

Outcome Measures

Primary Outcomes (1)

  • Safety evaluation by the incidence of adverse events (AEs) and serious adverse events (SAEs)

    Incidence of AEs and SAEs of each participant will be recorded and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0).

    24 months

Secondary Outcomes (3)

  • Overall response rate (ORR)

    24 months

  • Duration of response (DOR)

    24 months

  • Progression-free survival (PFS)

    24 months

Study Arms (1)

adoptive TKC transfer combined with chemotherapy

EXPERIMENTAL

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.

  • Prothrombin time (PT)/international normalized ratio (INR) \<1.5 ULN and partial thromboplastin time (PTT)/activated partial thromboplastin time (APTT) \<1.5 ULN;
  • Acceptable liver and kidney functions: aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤2.5 ULN in subjects without liver metastases and ≤3.5 upper limit of normal (ULN) in those with liver metastases; bilirubin≤1.5 ULN (excluding hyperbilirubinemia or non-liver-derived hyperbilirubinemia); creatinine ≤1.5 ULN and creatinine clearance rate≥40 mL/min;
  • Women of child-bearing age must be negative for pregnancy test at 7 days before initiation of the treatment.
  • Eastern Cooperative Oncology Group (ECOG) scores≤1.
  • Expected survival no less than 6 months.

You may not qualify if:

  • Participating in other clinical trials in the past 30 days;
  • Current on systemic steroid or steroid inhalers;
  • Active brain metastasis or spinal cord compression
  • Uncontrollable pleural and peritoneal effusion requiring clinical treatment or intervention;
  • Active bleeding, and thrombotic diseases requiring treatment;
  • Uncontrolled infectious diseases, such as baseline hepatitis B virus (HBV) DNA≥2000 IU/mL, positive for anti-human immunodeficiency virus (HIV) antibody and hepatitis C virus (HCV)-RNA; Other active infection with clinical significance;
  • Organ failure; Heart: Grade III and IV ; or with hypertension uncontrolled by the standard treatment, history of myocarditis or myocardial infarction within 1 year; Liver: Class C according to the Child-Turcottei-Pugh System (CTP); Kidneys: Kidney failure and uremic syndrome; Lungs: Serious symptoms of respiratory failure; Brain: Disturbance of consciousness;
  • Allergic diathesis and allergic to immunotherapy or relevant drugs;
  • Pregnancy or lactation;
  • History of other active malignancies in the past 5 years, excluding basal or squamous skin carcinoma, superficial bladder cancer, and breast cancer in situ which have completely healed and require no follow-up treatment;
  • Serious autoimmune diseases or immunodeficiency disease, including those with confirmed severe autoimmune diseases and requiring long-term use (over 2 months) of systemic immunosuppressants (steroids) or having immune-mediated symptomatic diseases, such as ulcerative colitis, Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus (SLE) and autoimmune vasculitis (eg., Wegener's granulomatosis);
  • Any mental diseases, including dementia and changes in mental status that may influence the understanding about the informed consent and questionnaire;
  • Judged as serious uncontrollable diseases by the researchers, or other conditions that may interfere with the treatment and therefore being ineligible.
