Long Term Follow-up Observational Study in Patients Treated with Gene-Modified T-Cell Therapy

February 8, 2025 updated by: CARsgen Therapeutics Co., Ltd.
This is a prospective long-term follow-up (LTFU) study to evaluate the long-term safety and survival benefit for patients who received at least one of CARsgen's GM T cell product in a clinical trial or as a commercially available product. In this study, patients will be followed for up to 15 years after last GM T-cell infusion for the evaluation of delayed adverse events (AEs), vector persistence, potential risk for integration, and survival time due to GM T-cell exposure.
