  • Research summary

    Research Summary:
    This trial is an open-label, multi-centre phase II study evaluating the long-term safety and clinical activity of clonal neoantigen reactive T cells (cNeT) in patients who have previously received ATL001 in a clinical trial.
    The primary objective of this trial is to assess the long-term safety and tolerability of ATL001 based on the frequency and severity of adverse events related to ATL001. The long-term clinical activity of ATL001 and requirement for cancer-related medical resources will also be evaluated as secondary objectives.
    Additional exploratory endpoints will be evaluated to further characterize ATL001 for clinical development.
    Patients will be enrolled after either: completing 2 years of follow-up visits in study ATX-NS-001 or study ATX-ME-001; or voluntary withdrawal from these aforementioned studies prior to the completion of the 2 year follow-up period.
    In this Long Term Follow Up Protocol, each patient will be followed up for a minimum period of 5 years, or until death if sooner.

    Lay summary of study results: For the whole duration of the study, 1 patient was enrolled onto the
    ATX-LTFU-001 clinical study and has since been transferred back to the original parent clinical study as part of its Long Term Follow-Up.
