Efficacy and Safety of Tisagenlecleucel in Adult Patients With Refractory or Relapsed Follicular Lymphoma

Phase 2
Active, not recruiting
Conditions
Follicular Lymphoma
Interventions
Registration Number
NCT03568461
Lead Sponsor
Novartis Pharmaceuticals
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.

Primary Outcome Measures
NameTimeMethod
Complete Response Rate (CRR) Per Independent Review Committee (IRC) Assessment1 year

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).

Secondary Outcome Measures
NameTimeMethod
Humoral Immunogenicity2 years

Antibody titers specific to the tisagenlecleucel molecule prior to and following infusion.

AUC0-84d; Cellular Kinetic Parameter of Tisagenlecleucel2 years

The AUC from time zero to day 84, in peripheral blood (%\*days or days\*copies/ µg)

Overall Response Rate (ORR) Per IRC Assessment1 year

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).
