Brief summary
This is a multi-center, phase II study to determine the efficacy and safety of tisagenlecleucel in adult patients with relapsed or refractory FL.
Detailed description
This single-arm, open label study had the following sequential phases: Screening, Pretreatment, Treatment and Follow-up. In the Pre-treatment phase, the patient could undergo bridging therapy (optional) and lymphodepleting (LD) chemotherapy. Treatment and Follow-up Phase included tisagenlecleucel infusion, and safety and efficacy follow-up for at least 24 months. For all the patients who received tisagenlecleucel infusion, additional survival follow-up was to be performed to determine survival status every 3 months.
Interventions
Tisagenlecleucel is single infusion.

Outcome results
Complete Response Rate (CRR) Per Independent Review Committee (IRC) Assessment
Complete response rate was defined as the percentage of participants with a best overall response (BOR) of complete response (CR) recorded from tisagenlecleucel infusion until progressive disease or start of new anticancer therapy, whichever came first. CRR was determined by an independent review committee (IRC) and was based on Lugano 2014 classification response criteria. The radiological response is first obtained from CT and PET studies according to the Lugano 2014 criteria. CT response is based on anatomical measurements of index/non-index/new lesions and spleen length. The possible response outcomes are complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD). PET response based on a 5-point scale (5PS) or Deauville score. The possible outcomes for PET response are complete metabolic response (CMR), partial metabolic response (PMR), no metabolic response (NMR), or progressive metabolic disease (PMD).
Time frame: 1 year
Population: Efficacy analysis set (EAS): All the patients who received tisagenlecleucel, and had measurable disease at baseline per IRC. Non-measurable disease at baseline is defined as absence of index lesion at baseline disease evaluation (i.e. no disease at baseline).

The AUC from time zero to day 84, in peripheral blood (%\*days or days\*copies/ µg)
Time frame: 2 years
Cellular Immunogenicity
Presence of T lymphocytes activated by the tisagenlecleucel protein
Time frame: 2 years
Cmax; Cellular Kinetic Parameter of Tisagenlecleucel

Time frame: 2 years
Duration of Response (DOR) Per IRC
Duration of response (DOR) applied only to participants whose best overall disease response was CR or PR. It is defined as the time from the date of first documented disease response (CR or PR) to the date of first documented progression or death due to follicular lymphoma (FL).
Time frame: 1 year
Humoral Immunogenicity
Antibody titers specific to the tisagenlecleucel molecule prior to and following infusion.
Time frame: 2 years
Overall Response Rate (ORR) Per IRC Assessment
Overall response rate is defined as the percentage of participants with a best overall disease response of complete response (CR) or partial response (PR). Response was evaluated per Lugano 2014 classification response criteria. The radiological response is first obtained from CT and PET studies according to the Lugano 2014 criteria. CT response is based on anatomical measurements of index/non-index/new lesions and spleen length. The possible response outcomes are complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD). PET response based on a 5-point scale (5PS) or Deauville score. The possible outcomes for PET response are complete metabolic response (CMR), partial metabolic response (PMR), no metabolic response (NMR), or progressive metabolic disease (PMD).
