What was measured

This is the summary cellular kinetic concentrations for CTL019 by flow cytometry. It evaluated the persistence of transduced CTL019 cells post-infusion. Observation was up to Month 6 for bone marrow.

Analysis population: PAS: The PAS consisted of patients in the FAS who had at least one sample providing evaluable cellular kinetic data for tisagenlecleucel parameter under investigation. Analysis of this particular outcome included a subset of PAS who had evaluation data of the parameter at the specific timepoint.

Groups in this outcome

Main Cohort: Single Dose of CTL019

Pediatric patients with relapsed or refractory B-cell ALL who were treated with single dose of tisagenlecleucel (CTL019).

Cohort 1: Single Dose of CTL019

Pediatric B-ALL patients who are very high risk at first relapse.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
