JW Therapeutics Achieves Breakthrough Designation for CART Therapy

Groundbreaking Progress in Cancer Treatment

JW Therapeutics (HKEx: 2126), a pioneering biotechnology company that specializes in cell immunotherapy, has made significant strides in the medical field. The company's innovative efforts were recently recognized when they announced that the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) has granted Breakthrough Therapy Designation for Carteyva (relmacabtagene autoleucel injection). This status applies to the use of Carteyva as a second-line treatment for adults suffering from relapsed or refractory large B-cell lymphoma (r/r LBCL).

An Effective Response to an Urgent Need

Large B-cell lymphoma is notorious for being a highly aggressive form of non-Hodgkin’s lymphoma, representing the most common subtype in adults. Although LBCL can be curable, alarming statistics show that about 30-40% of patients continue to experience either refractory or relapse symptoms. Those who fail to respond to the first line of treatment often face grim outcomes.

Traditional treatment methods, such as high-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (HDCT/ASCT), have become the standard of care. Yet, more than half of the patients are often ineligible for ASCT due to various reasons, including advanced age and underlying medical conditions. This highlights a critical gap in effective treatment options and an urgent need for innovative therapies to address r/r LBCL.

Clinical Study Insights

The Breakthrough Therapy Designation for Carteyva was underscored by promising findings from clinical studies that evaluated its efficacy and safety in Chinese adults suffering from r/r LBCL who were not candidates for autologous stem cell transplantation after initial treatment failure. Remarkably, these studies marked the first time clinical results were obtained from Chinese patients, showcasing the potential of Carteyva in this demographic.

Comprehensive Understanding of Carteyva

Relmacabtagene autoleucel injection, commonly known as Carteyva, is an innovative CAR-T cell immunotherapy developed independently by JW Therapeutics. It targets the CD19 protein on cancer cells and has obtained approval from the NMPA for treating multiple conditions, including relapsed or refractory large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma. This makes Carteyva a groundbreaking product, being the first CAR-T cell therapy approved as a Category 1 biologic in China.

Currently, it stands out as the only CAR-T product in the country that holds recognition under the National Significant New Drug Development Program, along with receiving priority review and breakthrough therapy designations.

Details on the Ongoing JWCAR029-216 Study

A phase II clinical trial known as the JWCAR029-216 study (NCT06093841) is currently in progress, aiming to assess the safety and efficacy of Carteyva among Chinese adults with r/r LBCL. This study is particularly noteworthy as it adheres to Chinese clinical practices, ensuring that the findings genuinely reflect the safety and efficacy in this specific group of patients. Preliminary results indicate that Carteyva demonstrates a remarkable best overall response rate of 84%, offering a beacon of hope for individuals battling this challenging condition.
