Key clinical point: Axicabtagene ciloleucel (axi-cel) led to a durable response and long-term survival in patients with refractory large B-cell lymphoma (LBCL), with no new safety signals.
Major finding : At a median follow-up of 63.1 months from infusion, the objective and complete response rates were 83% (95% CI 74%-90%) and 58% (95% CI 48%-68%), respectively. The median overall survival (OS) was 25.8 (95% CI 12.8-not estimable) months, and the 5-year OS rate was 42.6% (95% CI 32.8%-51.9%). No new treatment-related adverse events were observed.
Study details: This 5-year follow-up analysis of the ZUMA-1 study phase 2 included 101 adult patients with refractory LBCL (diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, and transformed follicular lymphoma) who received lymphodepleting chemotherapy followed by axi-cel infusion.
