JW Therapeutics Presents Latest Clinical Data on Carteyva® in Follicular Lymphoma and Mantle Cell Lymphoma at the 64th ASH Annual Meeting

SHANGHAI, Dec. 12, 2022 /PRNewswire/ — JW Therapeutics (HKEX: 2126), an independent and innovative biotechnology company focusing on developing, manufacturing and commercializing cell immunotherapy products, presented the latest clinical data on Carteyva® (relmacabtagene autoleucel injection) in Chinese adults with relapsed/refractory follicular lymphoma (r/r FL) and relapsed/refractory mantle cell lymphoma (r/r MCL) at the 64th American Society of Hematology (ASH) Annual Meeting.

Efficacy and Safety of Relmacabtagene Autoleucel in Adults with Relapsed/Refractory Follicular Lymphoma in China (abstract number: 4640)

In this pivotal phase II RELIANCE study, patients who had histologically confirmed grade 1, 2, or 3a FL, with r/r disease were included. Eligible patients were randomized to received relma-cel at the dose level of 100×106 or 150×106 CAR+ T cells, following lymphodepletion chemotherapy. At data cut-off (Dec 17, 2021), based on 28 patients with 11.7 months of median follow-up, relma-cel demonstrated remarkable clinical responses achieving high rates of complete response rate (CRR) and overall response rate (ORR) (6 months ORR, CRR were 100% and 83.33% respectively), and a manageable safety profile (only 1 patient experienced Gr ≥3 neurotoxicity (NT), no Gr ≥3 cytokine release syndrome (CRS)). Updated safety and efficacy data with a longer follow-up will be presented.

Preliminary Safety and Efficacy of Relmacabtagene Autoleucel (relma-cel) in Adults with Relapsed/Refractory Mantle Cell Lymphoma (r/r MCL) in China (abstract number: 3326)

In this phase II single-arm open-label study in China, participants with MCL underwent ≥2 lines of therapy including anti-CD20 antibody, anthracycline or bendamustine, and BTKis were included. After lymphodepleting chemotherapy, participants received relma-cel (100×106 CAR+ T cells). As of Nov 30, 2021, the preliminary data of relma-cel based on 11 patients provided promising clinical efficacy outcome (best ORR 81.8%, best CRR 54.5%) in high risk patients with r/r MCL and a low incidence of grade ≥ 3 CRS (1 patient) and immune effector cell-associated neurotoxicity syndrome (ICANS, 1 patient). This study is ongoing and further results will be presented.

About Relmacabtagene Autoleucel Injection (trade name: Carteyva®)

Relmacabtagene autoleucel injection (abbreviated as relma-cel, trade name: Carteyva®) is an autologous anti-CD19 CAR-T cell immunotherapy product independently developed by JW Therapeutics based on a CAR-T cell process platform of Juno Therapeutics (a Bristol Myers Squibb company). Being the first product of JW Therapeutics, relma-cel has been approved by the China National Medical Products Administration (NMPA) for two indications, including the treatment of adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, and the treatment of adult patients with follicular lymphoma that is refractory or that relapses within 24 months of second-line or above systemic treatment (r/r FL), making it the first CAR-T product approved as a Category 1 biologics product in China. Currently, it is the only CAR-T product in China that has been simultaneously included in the National Significant New Drug Development Program, priority review and breakthrough therapy designations.
