JW Therapeutics Presents Primary Clinical Response on Carteyva(R) (relmacabtagene autoleucel injection) in Adults with Relapsed/Refractory Follicular Lymphoma in China at the 63rd ASH Annual Meeting

SHANGHAI,Dec. 15,2021 -- 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."
