Clinical Trial Summary

This trial will compare tisagenlecleucel to standard of care in adult participants with relapsed or refractory (r/r) follicular lymphoma.

Description:

The purpose of this phase III study is to verify the clinical benefit of tisagenlecleucel for the treatment of r/r FL by comparing the tisagenlecleucel treatment strategy to standard of care therapy in patients with r/r FL after two or more lines of systemic therapy, with progression-free survival (PFS) as the primary endpoint. The primary objective is to demonstrate superiority of the tisagenlecleucel treatment strategy over standard of care (SOC) therapy with respect to progression-free survival (PFS) determined by blinded independent review committee (BIRC) based on the Lugano response criteria. Participants randomized to Arm A (tisagenlecleucel treatment) will receive a single infusion of 0.6 to 6 x 10^8 CAR-positive viable T-cells. Participants randomized to Arm B (Standard of Care) will receive R2 or R-CHOP based on investigator choice and this has to be determined prior to randomization.

5. Active neurological autoimmune or inflammatory disorders (e.g., Guillain-Barré syndrome).

6. Investigational medicinal product within the last 30 days or five half-lives (whichever is longer) prior to randomization.

7. Clinically significant cardiovascular conditions such as acute coronary syndrome, significant cardiac arrhythmias, heart failure or decreased LVEF. Other protocol defined inclusion/exclusion criteria may apply
