What was measured
DoR is defined as the time from first partial or complete response (CR or PR) to disease progression, start of new antineoplastic therapy due to efficacy concerns or death, whichever occurs first. CR: Target nodes masses must regress to ≤ 1.5cm in LDi, no extralymphatic sites, no new lesions. PR: ≥ 50% decrease in sum of diameters of up to 6 target nodes and extranodal sites, no new lesions, spleen must have regressed \> 50% in length. PD: LDi \> 1.5cm, increase by ≥ 50% from PPD nadir, an increase in LDi or SDi from nadir, 0.5 cm for lesions ≤ 2cm, 1.0cm for lesions \> 2cm. Complete metabolic response: Lymph nodes score 1, 2, 3 with/without residual mass on 5-point scale, no new lesions, no FDG-avid disease. Partial metabolic response: Lymph nodes score 4 or 5, reduced uptake from baseline, no new lesions, residual uptake higher than normal, reduced from baseline. Progressive metabolic disease: Score 4 or 5 with an increase in uptake intensity from baseline and/or new FDG-avid.
Analysis population: All randomized participants with PR or CR
Groups in this outcome
Standard of Care Arm
3 cycles of standard of care (SOC) salvage therapy (R-DHAP, R-ICE and R-GDP) per physician's choice. Participants responding to SOC are expected to undergo high dose chemotherapy (HDCT) and hematopoietic stem cell transplant (HSCT). If requested by the investigator, participants may be allowed to receive JCAR017 upon meeting progression, relapse, or suboptimal response. 1 cycle = 3 weeks
Liso-cel Arm
\[Lymphodepleting chemotherapy (LDC)\] Fludarabine IV (30 mg/m\^2/day for 3 days) and cyclophosphamide IV (300 mg/m\^2/day for 3 days) followed by JCAR017 IV infusion at a dose of 100 x 10\^6 JCAR017-positive viable transduced T cells (CAR+ T cells) on Day 29 (2 to 7 days after completion of LD chemotherapy)
