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 receive 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 Adult patients with Relapsed/Refractory Mantle Cell Lymphoma (r/r MCL) in China (abstract number: 3326)
People with MCL who took part in this phase II single-arm open-label study in China got at least two types of treatment, such as anti-CD20 antibodies, anthracycline or bendamustine, and BTKis. After lymphodepleting chemotherapy, participants received relma-cel (100×106 CAR+ T cells). As of Nov 30, 2021, the preliminary data based on 11 patients provided promising clinical efficacy outcomes (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.
