CAR-T Long Term Follow Up (LTFU) Study

Per Health Authorities guidelines for gene therapy medicinal products that utilize integrating vectors (e.g. lentiviral vectors), long term safety and efficacy follow up of treated patients is required. The purpose of this study is to monitor all patients exposed to CAR-T therapied for 15 years following their last CAR-T (e.g. CTL019) infusion to assess the risk of delayed adverse events (AEs), monitor for replication competent lentivirus (RCL) and assess long-term efficacy, including vector persistence.

Patients are enrolled following completion or early discontinuation from a Novartis sponsored or supported study of CAR T-Cell treatment. Patients will be followed for 15 years post treatment from the last treatment. They will be monitored for safety and efficacy within the primary treatment protocols for the protocol defined duration. Patients can drop off treatment protocols at any time to enter this long term Follow up study. Patients discontinuing from the primary treatment protocols for any reason will be enrolled in this long term follow up (LTFU). This will allow collecting data on long term safety and efficacy (as applicable) as mandated by the health authorities of all patients treated with CAR-T therapy within the concept of a single protocol.

Collection of such long term effects of CAR-T cell therapy will help to further define the risk-benefit profile of CAR-T Therapies.
