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.

This was a multi-center Phase II study investigating the efficacy and safety of reinfusion of tisagenlecleucel in pediatric and young adult patients with acute lymphoblastic leukemia (ALL) who were treated with tisagenlecleucel and experience B cell recovery.

This trial was a phase II, open label, multi-center trial to determine the efficacy and safety of tisagenlecleucel re-infusion in pediatric and adolescent young adult (AYA) patients with acute lymphoblastic leukemia (ALL) experiencing loss of B cell aplasia. Loss of B-cell aplasia is defined as: peripheral blood (PB) absolute B lymphocyte count ≥ 50/µL, OR PB B lymphocyte ≥ 10% of the total lymphocytes. B-cell aplasia is defined as PB absolute B lymphocyte count \<50/µL.

The study had the following phases for all patients: Screening, Treatment and Follow-up. The total duration of the study was about 12 months. After tisagenlecleucel re-infusion, efficacy was assessed at months 1, 3, 6, and End of Study at which time blood samples were obtained.

The study stopped early due to slow enrollment into the trial. The rate of enrollment made the trial no longer feasible to continue.

The patients were able to voluntarily withdraw from the study for any reason, at any time. Patients who received commercial tisagenlecleucel had to be followed for up to 15 years post-infusion. Patients could have been followed under the Center for International Blood and Marrow Transplant Research (CIBMTR) cellular therapy registry if consented for participation. For patients who do not provide consent for participation in the Center for International Blood and Marrow Transplant Research (CIBMTR) registry, adverse events were to be reported for 15 years or until the patient enrolls in the registry.

Novartis is committed to sharing with qualified external researchers, access to patient-level data and supporting clinical documents from eligible studies. These requests are reviewed and approved by an independent expert panel on the basis of scientific merit. All data provided is anonymized to respect the privacy of patients who have participated in the trial in line with applicable laws and regulations.

This trial data is currently available according to the process described on www.clinicalstudydatarequest.com.

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.

Overall remission rate (ORR) was defined as the percentage of participants with a best overall disease response of complete remission (CR) or CR with incomplete blood count recovery (CRi). However, the rate was not calculated due to low enrollment. Participants' best responses have been listed by day and participants may be counted more than once.

An event was defined as one of the following: death from any cause after remission, relapse, treatment failure (defined as no response in the study or discontinuation from the study for death, adverse event, lack of efficacy or progressive disease or new cancer therapy).
