Up to 90 patients with advanced non-small cell lung cancer ( NSCLC) or melanoma 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 studies prior to the completion of the 2 year of follow-up period.~Each patient will be followed up for a minimum period of 5 years, or until death if sooner, in this Long-Term Follow Up Protocol.~For patients who are still alive after 5 years of follow-up, survival data will continue to be collected until the end of the study, which will occur when the last patient has completed 5 years of follow-up withdraws from study or has died.
This is an Open-Label, Multi-Centre Phase II study to evaluate the long-term safety and clinical activity of ATL001, previously administered intravenously to patients in Study ATX-NS-001 (NCT04032847) or Study ATX-ME-001 (NCT03997474).
