Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - Tisagenlecleucel
Treatment: Drugs - Lenalidomide and rituximab (R2) in 28-day cycles for up to 12 cycles.
Treatment: Drugs - Rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone or prednisolone (R-CHOP) in 21-day cycles for 6 to 8 cycles
Treatment: Drugs - Lymphodepleting chemotherapy
Other interventions - Corticosteroids and/or Radiation (Bridging therapy)

Experimental: Tisagenlecleucel - Participants randomized to the tisagenlecleucel treatment strategy will receive a single infusion of 0.6 to 6 x 10\^8 CAR-positive viable T-cells

Active comparator: R2 or R-CHOP - Participants randomized to Standard of Care treatment will receive either R2 or R-CHOP based on investigator choice of therapies, and this has to be determined prior to randomization.


Treatment: Other: Tisagenlecleucel
Tisagenlecleucel is a solution for infusion of 0.6 to 6 x 10\^8 CAR-positive viable T-cells taken intravenously (i.v.).

Treatment: Drugs: Lenalidomide and rituximab (R2) in 28-day cycles for up to 12 cycles.
Lenalidomide 20 mg daily on days 1-21 for up to 12 cycles Rituximab 375 mg/m2 IV on days 1, 8, 15, and 22 of cycle 1 and day 1 of cycles 2-5

Treatment: Drugs: Rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone or prednisolone (R-CHOP) in 21-day cycles for 6 to 8 cycles
Rituximab 375 mg/m2 i.v. on day 1 Cyclophosphamide 750 mg/m2 i.v. day 1 Doxorubicin 50 mg/m2 i.v. day 1 Vincristine 1.4 mg/2 (capped at 2 mg) i.v. day 1 Prednisone or prednisolone 40 mg/m2 PO days 1-5

Treatment: Drugs: Lymphodepleting chemotherapy
Fludarabine (25 mg/m\^2 intravenously \[i.v.\] daily for 3 doses) OR Cyclophosphamide (250 mg/m\^2 i.v. daily for 3 doses starting with the first dose of fludarabine).

OR Bendamustine 90 mg/m\^2 i.v. daily for 2 days (If there was previous grade IV hemorrhagic cystitis with cyclophosphamide, or the participant demonstrated resistance to a previous cyclophosphamide-containing regimen)
