Key clinical point: Second-line lisocabtagene maraleucel (liso-cel) offers better efficacy over standard of care (SOC; platinum-based immunochemotherapy followed by high-dose chemotherapy+autologous stem cell transplantation [ASCT]) in chemotherapy-sensitive patients with relapsed/refractory large B-cell lymphoma (LBCL) along with a favorable safety profile.
Major finding: After a 17.5-month median follow-up, the liso-cel vs SOC group had significantly improved median event-free survival (hazard ratio [HR] 0.356; 95% CI 0.243-0.522), median progression-free survival (HR 0.400; P < .0001), and complete response rate (74% vs 43%; P < .0001), along with low grade 3 cytokine release syndrome (1%) and neurological event (4%) rates.
Study details: This phase 3 study, TRANSFORM, included 184 adult patients with relapsed/refractory LBCL who were eligible for high-dose chemotherapy+ASCT and were randomly assigned to receive liso-cel (100×10 6 chimeric antigen receptor-positive T cells) or three cycles of SOC.
Disclosures: This study was funded by Celgene, a Bristol-Myers Squibb Company. Some authors reported ties with various organizations, including Celgene. Three authors declared being employees of Celgene.
