Key clinical point: Bendamustine lymphodepletion (LD) relative to fludarabine/cyclophosphamide (Flu/Cy) LD prior to axicabtagene ciloleucel (axi-cel) therapy leads to comparable efficacy and lower rates of any-grade immune effector cell-associated neurotoxicity syndrome (ICANS) in patients with relapsed or refractory aggressive B-cell lymphoma (aBCL).

Major finding: The bendamustine and Flu/Cy cohorts had similar rates of best overall response (77.8%, 95% CI 57.7%-91.4%; and 81.0%, 95% CI 65.9%-91.4%, respectively) and complete response (48.1%, 95% CI 28.7%-68.1%; and 50.0%, 95% CI 34.2%-65.8%, respectively), 6-month progression-free survival (43.8%, 95% CI 24.7%-61.3%; and 55.6%, 95% CI 39.0%-69.3%, respectively), and 6-month overall survival (81.5%, 95% CI 61.1%-91.8%; and 90.4%, 95% CI 76.4%-96.3%, respectively). Bendamustine vs Flu/Cy was associated with decreased odds of any-grade ICANS (odds ratio 0.35; 95% CI 0.12-0.97).

Study details: This retrospective study included patients with relapsed or refractory aBCL who received bendamustine (n = 27) or Flu/Cy (n = 42) LD before axi-cel therapy.

Disclosures: This study did not receive any funding. Some authors declared serving as speaker's bureau members or consultants for or receiving research funding or honoraria from various organizations.
