Summary
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.
