- This global, phase 3 study compared lisocabtagene maraleucel (liso-cel) with standard of care (SOC) as second-line therapy for primary refractory or early relapsed (≤12 months) large B-cell lymphoma (LBCL). Adults eligible for autologous stem cell transplantation (ASCT) were randomized 1:1 to liso-cel (100×106 CAR+ T cells) or SOC (3 cycles of platinum-based immunochemotherapy followed by high-dose chemotherapy and ASCT in responders). The primary end point was event-free survival (EFS) by independent review. A total of 184 patients were randomized. In this primary analysis with a median follow-up of 17.5 months, median EFS was not reached (NR) for liso-cel versus 2.4 months for SOC (hazard ratio [HR] = 0.356; 95% confidence interval [CI]: 0.243‒0.522). Complete response (CR) rate was 74% for liso-cel versus 43% for SOC (P < .0001) and median progression-free survival (PFS) was NR for liso-cel versus 6.2 months for SOC (HR = 0.400; 95% CI: 0.261‒0.615; P < .0001). Median overall survival was NR for liso-cel versus 29.9 months for SOC (HR = 0.724; 95% CI: 0.443‒1.183; P = .0987). When adjusted for crossover from SOC to liso-cel, median overall survival was NR for liso-cel and SOC (HR = 0.415; 95% CI: 0.251‒0.686). Grade 3 cytokine release syndrome and neurological events occurred in 1% and 4% of patients in the liso-cel arm, respectively (no grade 4/5 events). These data show significant improvements in EFS, CR rate, and PFS for liso-cel over SOC and support liso-cel as a preferred second-line treatment compared with SOC in patients with primary refractory or early relapsed LBCL.

- The JULIET phase 2 trial evaluated a single infusion of tisagenlecleucel in adult patients with relapsed/refractory (r/r) diffuse large B-cell lymphoma (DLBCL). The objective of the current analysis was to evaluate patient-reported health-related quality of life (HRQoL) with a median follow-up of 19.3 months among patients infused with a single dose of tisagenlecleucel. Patients enrolled were ≥18 years of age with r/r DLBCL after ≥2 lines of therapy and had either undergone a failed autologous stem cell transplant or were ineligible for the procedure. Two validated HRQoL instruments, Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) and Short Form-36 (SF-36) Health Survey, were used to measure HRQoL at baseline and months 3, 6, 12, and 18. At data cutoff (21 May 2018), 115 patients had received tisagenlecleucel infusion. Among the 99 patients evaluated, overall response rate was 54%, and 40% of patients achieved complete response (CR). Initially, 108 patients completed the HRQoL assessments at baseline, including 57 patients who eventually achieved CR or partial response (PR). Further, 30 and 21 patients in clinical response who completed assessments at baseline also completed assessments at months 12 and 18, respectively. Patients who achieved CR or PR sustained HRQoL improvement in all FACT scores at all time points. SF-36 instruments showed improvement above the minimal clinically important differences on 5 of 8 subscales. Long-term follow-up in the phase 2 JULIET study demonstrated that patients with r/r DLBCL who respond to tisagenlecleucel therapy had sustained, clinically meaningful improvements in HRQoL. This trial was registered at www.clinicaltrials.gov as #NCT02445248.
