Advanced Non Small Cell Lung Cancer | Biological: ATL001 Drug: Pembrolizumab | Phase 1 Phase 2 |
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 be followed up for a period of 24 months post ATL001 infusion in the study. Patients will then be requested to enter a separate long term follow up protocol for a further 5 years (total 84 months)

- Assessment of Treatment Emergent Adverse Events (TEAEs) to evaluate Safety and Tolerability [ Time Frame: 84 months ]Evaluate TEAEs and serious AEs, by incidence, severity and relationship to ATL001
- Disease Assessment for Change from Baseline in Tumour Size [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate the clinical activity of ATL001 in patients with advanced NSCLC using change from baseline in tumour size at week 6 , week 12 and best overall change from baseline, as assessed by investigator and independent central review (ICR)
- Disease Assessment for Objective Response Rate (ORR) [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate the endpoint of ORR as assessed by investigator and ICR, per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune modified RECIST( im-RECIST).
- Disease Assessment for Time to Response (TTR) from ATL001 infusion [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate the endpoint of TTR by the investigator and ICR, per RECIST v1.1 and im-RECIST
- Disease Assessment for Duration of Response (DoR). The DoR is defined as the time from the date of first documented response until the date of documented disease progression or death [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate the endpoint of DOR by the investigator and ICR, per RECIST v1.1 and im-RECIST
- Disease Assessment for Disease Control Rate (DCR) [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate the endpoints of DCR as assessed by the investigator and ICR per RECIST v1.1 and im-RECIST
- Disease Assessment for Progression-Free Survival (PFS) [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate the efficacy endpoints of PFS as assessed by the investigator and ICR per RECIST v1.1 and im-RECIST
- Overall Survival (OS) [ Time Frame: Every 6 weeks for 6 months, then every 3 months for a maximum of 84 months ]Evaluate OS by the investigator
