Details and patient eligibility


A single-center, open-label pilot study to determine the safety, tolerance and engraftment potential of zeushield cytotoxic T lymphocytes in subjects with PD-L1+ positive non-small cell lung cancer.

Full description

The purpose of this first in human study is to determine the safety and feasibility of Zeushield Cytotoxic T Lymphocytes(Z-CTLs) in patients with relapsed or refractory NSCLC. Z-CTLs therapy is a novel immunotherapy under investigation in which patients have their T-cells (a type of white blood cell) collected and modified in the laboratory, before they are given back to the patient. The T-cells are modified to transform the intracellular signal domain of PD-1 and CTLA-4 to immune activation stimulus signal and transform T cells to a new kind of cancer-killer cells: zeushield cytotoxic T lymphocytes (Z-CTls).

  • HIV/AIDS infection
  • active infection
  • previously suffered from diseases or concurrent diseases as followed:
  • patients confirmed as severe autoimmune diseases in long-term (over 2 months) need of systemic immune inhibitors (steroid) or as immune-mediated symptomatic diseases including ulcerative colitis, Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus (SLE), autoimmune vasculitis (for example, Wegener's granulomatosis)
  • subjects with previous diagnosis as motor neurone disease caused by autoimmunity
  • subjects previously suffered from toxic epidermal necrolysis (TEN)
  • subjects with any mental diseases including dementia, mental status change that may impinge the understanding and performance of informed consent and related questionnaire
  • subjects with severe, uncontrollable diseases judged by investigators that may hinder them receiving this treatment
  • subjects with previously active malignant tumors including basal or squamous skin cancer, superficial bladder cancer, and in situ breast carcinoma within 5 years who had been completely cured without the need of follow-up treatment are not excluded.
  • during ongoing treatment using systemic steroid or steroid inhalants
  • subjects with unstable or active peptic ulcer or alimentary tract hemorrhage
  • subjects with previous organ transplantation or ready for organ transplantation
  • subjects in need of anticoagulant therapy treatment (warfarin or heparin)
