While China leads in terms of ongoing trials, only two CAR T treatments have been approved: axicabtagene ciloleucel and relmacabtagene autoleucel, indicating accessibility challenges due to regulatory and economic constraints.
China is leading the way in CAR T-cell therapy innovation, addressing safety concerns, and investigating novel targets and dual-targeting. Although there are still obstacles in the way of wider patient access, the future of this game-changing treatment is bright.
Key Areas Of Progress In Chimeric Antigen Receptor T-Cell Therapy In China
Targeting Solid Tumors
Challenge: Traditionally, CAR T therapies have shown greater success in blood cancers than solid tumors due to complex tumor microenvironments and antigen heterogeneity.
Progress: Several Chinese trials are looking at new ways to target solid tumors.
Trials evaluating CAR T cells that express two different receptors and target several tumor antigens for increased efficacy (e.g., BCMA/CD19 for multiple myeloma, GD2/NGFR for neuroblastoma).
Studies are looking into personalized TIL-based CAR T cells tailored to each patient’s tumor, with encouraging early results in lung cancer and melanoma.
Combining CAR T cells with additional treatments such as checkpoint inhibitors or radiation has the potential to improve response and overcome resistance in solid tumors.
For example: A Phase I trial (NCT05424241) using a dual CAR T cell targeting BCMA and CD19 in relapsed/refractory multiple myeloma found encouraging safety and effectiveness findings, including full responses in certain patients.
Overcoming Toxicity Challenges
Challenge: Cytokine release syndrome (CRS) and neurotoxicity are severe side effects of CAR T therapy that raise safety concerns.
Progress: Chinese researchers are finding techniques to treat and reduce these toxicities:
Trials are being conducted on CAR T cells with changes such as “suicide genes” to allow for easy removal if significant side effects arise.
Drugs targeting specific pathways involved in CRS or neurotoxicity are being tested in combination with CAR T therapy to reduce severe reactions.
To reduce toxicity risks, CAR T cell doses and treatment plans are being tailored to specific patient’s characteristics.
For example, a Phase I/II trial (NCT04552054) using a BCMA-targeted CAR T cell with a “suicide gene” in multiple myeloma patients showed promising safety and controllable CRS, as well as encouraging effectiveness results.
Achieving Durable Responses
Challenge: CAR T cell therapy continues to face challenges in maintaining long-term tumor control and preventing relapse.
Progress: Efforts are ongoing to improve the persistence and lifetime of CAR T cells:
Trials are being conducted on CAR T cells modified to establish memory function, which could lead to longer-lasting anti-tumor actions.
Methods for stimulating CAR T cell expansion within the patient’s body following infusion are being investigated to improve their persistence and efficiency.
Researchers are looking into combining CAR T cells with other immune-stimulating drugs to provide a more long-lasting anti-tumor response.
For example, a Phase I/II trial (NCT04418739) evaluating a CD19-targeted CAR T cell with memory capabilities in B-cell leukemia revealed persistent complete responses in a large number of patients after 12 months, indicating better long-term efficacy.
