Key information

About this study

This is a non-therapeutic study design. After successful screening, subjects will be monitored for potential gene therapy-related adverse events for up to 15 years post MB-CART2019.1 infusion. Subjects will be assessed yearly for the occurrence of delayed adverse events (AEs), monitored for replication competent lentivirus (RCL) and assessed for long term efficacy as well as CAR-T persistence.

Primary outcomes

  1. Number of subjects with new or recurrence of pre-existing malignancy

    Time frame: Up to 15 years

  2. Number of subjects with new incidence or exacerbation of a pre-existing neurological disorder

    Time frame: Up to 15 years

  3. Number of subjects with new incidence or exacerbation of pre-existing rheumatologic or other autoimmune disorders

    Time frame: Up to 15 years

  4. Number of subjects with new incidence of Grade ≥ 3 hematologic disorders

    Time frame: Up to 15 years

  5. Number of subjects with related AEs, related SAEs, and all AESIs

    Time frame: Up to 15 years

    AESIs will be collected

Secondary outcomes

  1. Number of subjects with measurable replication competent lentivirus in peripheral blood (if positive at study entry)

    Time frame: Up to 15 years

    Peripheral blood samples may be collected for RCL assessment

  2. Duration of zamtocabtagene autoleucel persistence

    Time frame: Up to 15 years

    Peripheral blood samples will be collected to test for CAR T cells

  3. Objective Response Rate (ORR)

    Time frame: Up to 15 years

    ORR for subjects who did not have progressive disease at their last assessment in the parent study; will be assessed by IRC and Investigator using Lugano 2014 Criteria for DLBCL and SCNSL and using IPCG Criteria (Abrey 2005) for PCNSL

  4. Overall Survival

    Time frame: Up to 15 years

    OS, measured from the date of zamtocabtagene autoleucel infusion to the date of the subject's death or the date the subject is last to known to be alive

  5. To determine the number of subjects who relapse after zamtocabtagene autoleucel infusion during LTFU

    Time frame: Up to 15 years

    Disease relapse: Number of subjects who enter the study as responders and relapse

  6. To assess immune reconstitution based on the recovery of total lymphocytes

    Time frame: Up to 15 years

    Change from baseline in peripheral B cell and lymphocyte levels
