Interim analysis of ZUMA-5: A phase II study of axicabtagene ciloleucel (axi-cel) in patients (pts) with relapsed/refractory indolent non-Hodgkin lymphoma (R/R iNHL)
Abstract No : 8008
Indication : indolent Non-Hodgkin's Lymphoma
Intervention : Yescarta
Company : Kite, a Gilead Company
Technology : CAR T Cell therapy
As of 8/20/19, 94 pts (80 FL; 14 MZL) received axi-cel with a median follow-up of 11.5 mo (range, 4.2 – 24.9). Median age was 63 y (range, 34 – 79), 47% of pts were male, 52% had stage IV disease, 51% had ≥ 3 FLIPI, and 59% had high tumor bulk (GELF). Pts had a median 3 prior lines of therapy, 66% progressed < 2 y after initial anti-CD20 mAb-containing therapy (POD24), and 73% were refractory to the last prior treatment. Of 87 pts evaluable for efficacy, ORR was 94% (79% complete response [CR] rate). Pts with FL (n = 80) had an ORR of 95% (80% CR rate). Pts with MZL (n = 7) had an ORR of 86% (71% CR rate). Overall, 68% of pts had ongoing responses as of the data cutoff. Updated data, including DOR, PFS, and OS with longer follow-up, will be included in the presentation. Of 94 pts evaluable for safety, 83% experienced Grade ≥ 3 adverse events (AEs), most commonly neutropenia (33%) and anemia (28%). Grade ≥ 3 cytokine release syndrome (CRS; per Lee et al, Blood 2014) and neurologic events (NEs; per CTCAE v4.03) occurred in 11% and 19% of pts, respectively. Median times to onset of CRS and NEs were 4 and 7 d, with median durations of 6 and 14.5 d. There were 2 Grade 5 AEs: multisystem organ failure in the context of CRS (related to axi-cel) and aortic dissection (unrelated to axi-cel). Median peak and AUC0-28 CAR T cell levels were 44 cells/µL and 490 cells/µL × d, respectively.
Axi-cel demonstrated significant and durable clinical benefit, with high rates of ORR and CR, and a manageable safety profile in pts with R/R Inhl.
Impressive response rates in heavily pre-treated patient pool, Patients with FL had CR of 80%.
