Outcome Measures

Primary Outcomes (1)

  • Percentage of Patients Who Establish B Cell Aplasia Within 9 Months of Reinfusion

    Percentage of patients who establish B-cell aplasia at any visit following re-infusion with tisagenlecleucel. B-cell aplasia is defined as peripheral blood (PB) absolute B lymphocyte count \<50/μL. Planned timeframe was 12 months but actual timeframe was approximately 9 months due to early termination of the trial. Day 1 is post lymphodepleting chemotherapy and pre-reinfusion of tisagenlecleucel.

    Post-reinfusion up to 9 months (Day 1 is excluded)

Secondary Outcomes (3)

  • Complete Response (CR) or Complete Response With Incomplete Blood Count Recovery (CRi) by Day

    Post-reinfusion up to 9 months

  • Participants With an Event

    Reinfusion up to 9 months

  • Overall Survival (OS)

    Reinfusion up to 9 months

Study Arms (1)

Biological: Tisagenlecleucel

Interventions

Tisagenlecleucel Cell Dispersion for Infusion given once during the study. The approved dose range for tisagenlecleucel is: 0.2 to 5.0×106 CAR positive viable T cells / kg for patients' ≤ 50 kg body weight or 0.1 to 2.5×108 CAR-positive viable T cells for patients \> 50 kg body weight.
