Axi-Cel Superior to SOC in Elderly Patients with Diffuse Large B-Cell Lymphoma

Jason Westin, MD, FACP, leader, DLBCL research team, MD Anderson Cancer Center, discussed results from the ZUMA-7 trial at ASCO 2022.

“For patients with relapsed refractory diffuse large B cell lymphoma, one of the big unmet needs is what to do for patients who are frail...The ability for us to deliver a therapy such as CAR T-cell in a patient population that historically has been considered as potentially not eligible for transplant would be a very important unmet need for us to define with this clinical trial.”

Axicabtagene ciloleucel (axi-cel; Yescarta; Kite) has demonstrated superiority to standard-of-care (SOC) chemotherapy in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) over the age of 65 years, according to new data from the ZUMA-7 study (NCT03391466).

These data were presented at the 2022 American Society of Clinical Oncology (ASCO) meeting, held June 3-7, 2022, held both virtually and in Chicago, Illinois, by Jason Westin, MD, FACP, leader, DLBCL research team, MD Anderson Cancer Center.

ZUMA-7 has enrolled 109 elderly patients as of March 18, 2021, 51 to the axi-cel arm and 58 to the SOC arm. Participants in the axi-cel arm had a median age of 70 years (range, 65-80) and participants in the SOC arm had a median age of 69 years (range, 65-81). The axi-cel arm had more participants with high-risk features, including second-line adjusted International Prognostic Index scores of 2-3 in 53% of participants and elevated lactate dehydrogenase in 61% of participants, compared with 31% and 41% in the SOC arm, respectively.

Westin and colleagues found that the axi-cel arm had superior event-free survival compared to the SOC arm (hazard rate, 0.276; P <.0001) and higher complete response rates (75% vs 33%). Quality of life analyses from 46 patients in the axi-cel arm and 42 in the SOC arm also revealed statistically significant and clinically meaningful score differences with axi-cel treatment. Score changes from baseline to day 100 after treatment were significantly better in the axi-cel arm for EORTC global health (P <.0001) and physical functioning domains (P = .0019), as well as the EQ-5D-5L visual analogue scale (P <.0001). Scores continued to favor the axi-cel arm over SOC at day 150 (P <.05).

Axi-cel had a managable safety profile in study participants, although most experienced at least grade 3 treatment-emergent adverse events (AEs; 94%). Similarly, most patients receiving SOC chemotherapy also experienced these AEs (82%). A grade 5 treatment-related AE occurred in 1 patient in the SOC arm and none in the axi-cel arm.

CGTLive spoke with Westin to learn more about the ZUMA-7 trial and the unmet needs of elderly patients with DLBCL. He also discussed the importance of enrolling diverse patient populations in clinical trials.
