Sufferers with early relapsed or refractory massive B-cell lymphoma had considerably improved total survival when handled with the chimeric antigen receptor (CAR) T cell remedy axicabtagene ciloleucel (axi-cel) when in comparison with the present standard-of-care chemoimmunotherapy, based on Outcomes of the Section III ZUMA-7 trial reported by researchers from The College of Texas MD Anderson Most cancers Middle.
Knowledge from the examine had been offered right this moment by Jason Westin, MD, director of scientific analysis within the Division of Lymphoma and Myeloma, on the 2023 American Society of Medical Oncology (ASCO) Annual Assembly and revealed concurrently within the New England Journal of Drugs.
At a median follow-up of 47.2 months, axi-cel demonstrated a statistically vital enchancment in total survival (OS) over customary remedy. The median OS had not but been reached for axi-cel, which means greater than half of the sufferers remained alive on the time of this evaluation, in comparison with a median OS of 31.1 months on the management arm. The estimated four-year survival price was 54.6% with axi-cel and 46% with customary care, comparable to a 27.4% discount within the threat of loss of life with the cell remedy.
That is the primary randomized section III trial in practically 30 years to enhance total survival with second-line healing remedy for sufferers with aggressive lymphoma. Excessive-dose chemotherapy and stem cell transplant, the outdated customary, cured a small portion of sufferers however resulted in unintended effects for all. The standard of life for sufferers handled with axi-cel improved quicker than these handled with chemotherapy, and our outcomes help axi-cel as a second-line therapy for these sufferers.”

B-cell lymphoma is a kind of non-Hodgkin lymphoma that originates within the B cells. In keeping with the American Most cancers Society, B-cell lymphomas account for about 85% of all lymphomas within the US Diffuse massive B-cell lymphoma is the most typical, with practically 30,000 individuals throughout the nation newly recognized every year. Axi-cel was accepted by the Meals and Drug Administration in 2017 for the therapy of particular sufferers with B-cell lymphomas, and ongoing research proceed to guage the advantages of this remedy relative to present customary approaches.
The worldwide ZUMA-7 trial included 359 sufferers who had been refractory or relapsed inside one 12 months of finishing first-line remedy. Sufferers had been randomized to obtain both axi-cel, an autologous anti-CD19 CAR T cell remedy, or customary of care, which consists of two to a few cycles of chemoimmunotherapy adopted by high-dose chemotherapy with autologous stem-cell transplantation in responding sufferers.
Sufferers receiving axi-cel achieved a median progression-free survival (PFS) of 14.7 months versus 3.7 months with customary remedy, with an estimated four-year PFS price of 41.8% versus 24.4% with customary remedy. The OS and PFS advantages favoring axi-cel had been constant throughout all key affected person subgroups.
The protection of axi-cel was manageable and according to earlier trials. In these handled with axi-cel, grade 3 cytokine launch syndrome occurred in 6% of sufferers and grade 3 or increased neurologic occasions occurred in 21% of sufferers, as reported within the major event-free survival evaluation. No new cytokine launch syndrome occasions had been recorded.
“On this groundbreaking trial, extra sufferers lived longer with axi-cel in comparison with the usual therapy. That is the primary trial in any most cancers kind the place a CAR T cell remedy improved survival versus older chemotherapy. That is an unimaginable breakthrough, however we proceed to work to be taught the place else CAR T cell remedy can show to be superior in treating sufferers with high-risk B-cell lymphoma,” Westin stated. “We at the moment are enrolling sufferers in a examine in first-line remedy, the ZUMA-23 scientific trial, to guage axi-cel in contrast with chemotherapy.”
The trial was funded by Kite Pharma, a Gilead Firm. Westin receives analysis help and served on the advisory board and as a guide for Kite Pharma. A full record of co-authors and their disclosures could also be discovered right here.
