Chinese Scientists Break CAR-T Therapy's "Sky-High Price" Barrier: Allogeneic Universal CAR-T Costs Reduced to Below $10,000
A breakthrough by East China Normal University (ECNU) Professor Du Bing and his team, in collaboration with Shanghai Changzheng Hospital and Zhejiang University Second Hospital, has been selected as one of the top ten domestic and international scientific news stories of 2024. This innovation not only overcomes the rejection challenges of allogeneic CAR-T cells but also slashes treatment costs to 1% of autologous CAR-T therapies, offering new hope to global patients.
Crushing the "Sky-High Price" Barrier: From Personalization to Mass Production
Traditional CAR-T therapy requires extracting a patient’s own T cells for gene editing, a personalized process that drives exorbitant costs. The first approved CAR-T product globally cost $475,000, while the lowest-priced domestic product remains at RMB 999,000 (≈$140,000). However, Du Bing’s team developed a novel gene-editing strategy targeting five critical genes in donor T cells, effectively masking the human leukocyte antigen (HLA) "identity barcode." This enables mass production of "off-the-shelf" allogeneic CAR-T cells, reducing manufacturing costs to 1% of autologous therapies. Once commercialized, this product, named TyU19, is expected to cost under RMB 100,000 (≈$14,000), marking a tenfold price reduction.
Technical Advantages: Safety and Efficacy Breakthroughs
Unlike international counterparts requiring pre-treatment immunosuppression, Du’s team’s allogeneic CAR-T cells evade immune recognition entirely, significantly lowering infection risks. Clinical trials demonstrated remarkable outcomes in severe autoimmune diseases, including immune-mediated necrotizing myopathy and systemic sclerosis. One paralyzed patient regained mobility within three months, driving complete remission in all three trial participants. Published in 《Cell》, this study represents the first global success of allogeneic CAR-T in autoimmune diseases.
Broader Applications and Industrialization Prospects
The TyU19 product has already achieved 100% complete remission in acute lymphoblastic leukemia patients. In 2025, the team plans to expand clinical trials to systemic lupus erythematosus, hematologic malignancies, and solid tumors. Collaborations with biotech firms like Shanghai Bangyao Biotechnology aim to scale production, potentially establishing a "Shanghai-made" CAR-T technology cluster. Recognized by 《Science》 magazine as a 2024 breakthrough, this innovation underscores China’s leadership in cell therapy.
Conclusion: From "Catch-Up" to "Pioneering"**
This breakthrough signifies China’s transition from follower to leader in CAR-T innovation. Chinese scientists are addressing global healthcare disparities, ensuring cutting-edge therapies benefit broader populations. As allogeneic CAR-T therapies advance, the era of "sky-high" medical costs may soon become a relic.
