China’s investigator trials accelerate competitive CAR T development

China’s CAR T market is expected to grow from $72 million in 2022 to $342 million over the next decade. There are currently more than 400 CAR T therapies in the pipeline in China, and most of these are being developed by specialized Chinese biotechs. Research by Clarivate plc, BioWorld’s parent company, indicates that a notable proportion of CAR T-cell therapies in late-phase development in China are being developed through strategic partnerships and joint ventures between multinational corporations and domestic companies, including Johnson & Johnson and Nanjing Legend Biotech Corp., Juno Therapeutics Inc. and Wuxi Apptec Co. Ltd., and CASI Pharmaceuticals Inc. and Juventas Cell Therapy Ltd.

CAR T pipelines bloom to treat world’s largest cancer population

As of Jan. 31, 2024, there were more than 300 CAR T trials registered in China, surpassing the U.S. and becoming the country with the most CAR T therapy clinical trials. Among them, CD19 is the most frequently studied target, according to BioWorld and Cortellis. The rapid evolution of CAR T-cell therapies in China has escalated over the past decade from the start of the first clinical trials in 2013 to the country becoming an established host for CAR T-cell-related trials by 2017, according to Yongxian Hu and researchers from Zhejiang University in Hangzhou, China. Chinese cell therapy companies – backed by $2.37 billion in funding in 2021 – have since significantly increased basic research and trial output for CAR Ts, which was welcomed by large patient demand.

China grapples with providing access to CAR T therapies

The process of manufacturing autologous T-cell therapies is technically challenging when compared with other oncology drugs, making the overall cost of developing CAR T therapies significantly higher. A challenging reimbursement environment for drugs listed on China’s National Reimbursement Drug List also means that most patients will have to pay out of pocket to access CAR T therapies. Taken together, complex logistics – production, manufacturing and supply chain – and complicated administration requirements are key bottlenecks that inflate the input costs involved in developing these specialized treatment options.
