ClinicalTrials ID:NCT04032847

Patient View

This phase I/IIa study evaluates the safety and clinical activity of ATL001, an autologous T cell therapy, in adults with advanced NSCLC. Eligible patients, aged 18-75 with smoking-related NSCLC, will receive ATL001 post-lymphodepletion. Pembrolizumab may also be administered. Participants must have ECOG 0-1, adequate organ function, and a life expectancy of ≥6 months.

Patient Parameters

Program Overview

This is a first-in-human, open-label, multi-centre, phase I/IIa study to characterise the safety and clinical activity autologous clonal neoantigen reactive T cells (cNeT) administered intravenously in adults with advanced non-small cell lung cancer (NSCLC).

Description

This is a first-in-human, open-label, multi-centre, phase I/IIa study to characterise the safety and clinical activity of autologous clonal neoantigen reactive T cells (cNeT) administered intravenously in adults with advanced non-small cell lung cancer (NSCLC).

Patients will initially enter the study for procurement of tumour materials required to manufacture ATL001.

Following manufacture of ATL001, the product will be given back to eligible patients following lymphodepletion. Patients will continue to be followed up for a minimum of 5 years, as part of a separate Long Term Follow Up Protocol, or, if the separate protocol is not available at the study site, within this protocol.

Eligibility Criteria

Inclusion Criteria

  1. Patient must be at 18-75 years old.
  2. Patients must have confirmed diagnosis of non-small cell lung cancer that is considered to be smoking related.
  3. Patient is considered medically fit to undergo procurement of starting material and ATL001 administration procedures.
  4. ECOG Performance Status 0-1.
  5. Adequate organ function per the laboratory parameters defined in the protocol.
  6. Anticipated life expectancy ≥ 6 months at the time of tissue procurement.
  7. Measurable disease according to RECIST 1.1 criteria.

Additional Inclusion Criteria will apply as per the protocol.

Exclusion Criteria

  1. Patients with untreated, symptomatic or progressing CNS metastases. Lesions should be clinically and radiologically stable for 2 months after treatment and should not require steroids.
  2. Patients with hepatitis B or C, human immunodeficiency virus infection (HIV1/2), syphilis or HTLVI/II infection.
  3. Patients for whom there is documented evidence of an actionable tumour driver oncogene mutation (EGFR, ALK or ROS-1) at the time of initial screening. Patients who have progressed on standard targeted therapies, or for whom no approved targeted treatments are available, are not excluded.
  4. Patients requiring immunosuppressive treatments.
  5. Patients requiring regular steroids at dose higher than prednisolone 10mg/day (or equivalent)
  6. Patients with superior vena cava syndrome.
  7. Patients with clinically significant, progressive, and/or uncontrolled renal, hepatic, haematological, endocrine, pulmonary, cardiac, gastroenterological or neurological disease.
  8. Patients with a history of immune mediated central nervous system toxicity, or a history of ≥ Grade 2 diarrhoea/colitis within the past 6 months caused by previous immunotherapy.
  9. Patients with an active concurrent cancer or a history of cancer within the past 3 years (except for in situ carcinomas, early prostate cancer with normal Prostate- Specific Antigen (PSA) or non-melanomatous skin cancers)
  10. Patients with a history of organ transplantation
  11. Patients who have previously received any investigational cell or gene therapies

Additional Exclusion Criteria will apply as per the protocol.
