tisagenlecleucel 在复发/难治性滤泡性淋巴瘤日本成人患者中的疗效和安全性：II 期 ELARA 试验结果

Tisagenlecleucel yielded a high durable response rate in patients with relapsed/refractory (r/r) follicular lymphoma (FL) in the global phase 2 ELARA trial. Here, we report the efficacy, safety, and cellular kinetics of tisagenlecleucel in a subgroup of Japanese patients with r/r FL from ELARA.

ELARA (NCT03568461) is a global single-arm trial of tisagenlecleucel in patients with r/r FL who received 2 prior lines of therapy. The primary endpoint was the complete response rate (CRR), and the secondary endpoints were the overall response rate, duration of response, progression-free survival, overall survival, safety, and cellular kinetics.

As of March 29, 2021, nine Japanese patients were enrolled and received tisagenlecleucel with a median follow-up of 13.6 months (range, 10.5 19.3). Per independent review committee, CRR was 100% (95% CI 63.1 100). Within 8 weeks of infusion, cytokine release syndrome (CRS) of any grade was reported in 6 patients (66.7%); however, no grade 3 CRS or any grade serious neurological events or treatment-related deaths were observed.

Tisagenlecleucel showed high efficacy and manageable safety in adult Japanese patients with r/r FL. Moreover, the clinical outcomes were similar to the global population, which supports the potential of tisagenlecleucel in Japanese patients with r/r FL.
