JW Therapeutics (HKEx: 2126), an independent innovative biotechnology company focused on developing, manufacturing and commercializing cell immunotherapy products, presented the primary clinical response on Carteyva? (relmacabtagene autoleucel injection) in adults with relapsed/refractory follicular lymphoma (r/r FL) in China at the 63rd American Society of Hematology (ASH) Annual Meeting.

As of the data cut-off of September 10, 2021, 28 patients were treated with Carteyva? with at least three months of follow-up.

Of 27 efficacy evaluable patients, as assessed by the investigator, best overall response rate (ORR) was 100% (27/27) and best complete response rate (CRR) was 92.6% (25/27). With a median follow-up of 8.84 months, the median duration of response (DOR), progression-free survival (PFS) and overall survival (OS) were not reached.

In 28 patients who received Carteyva?, any grade and severe (grade≥3) cytokine release syndrome (CRS) were 42.9% and 0%, respectively, and any grade and severe (grade≥3) neurotoxicity (NT) were 17.9% and 3.6%, respectively.

Dr. Mark J. Gilbert, Chief Medical Officer of JW Therapeutics, commented: "Most patients with r/r FL remain incurable and eventually relapse or progress. Results from this pivotal study provide evidence that Carteyva? can result in high tumor remission rates and a manageable toxicity profile in r/r FL patient. Encouraged by these findings, we are looking forward to expanding the indications of Carteyva? use into r/r FL, hopefully benefiting more patients soon."
