BRL Medicine's new generation of CD19 UCAR-T products

a new generation of UCAR-T product developed based on the self-developed universal cell platform (TyUCell ^® ), which is mainly transformed by gene editing technology Allogeneic immune cells effectively avoid the risks of GVHD and HVG that may exist in allogeneic cell transplantation. On the basis of ensuring the safety and effectiveness of cell products, it truly realizes the generalization of immune cell therapy products. The indication field of the product layout A B-cell malignancy.

Compared with similar products at home and abroad, BRL Medicine's new generation CD19 UCAR-T product has the following clinical advantages:

01 Great Patient Accessibility

03 Better clinical treatment effect

The T cells of BRL Medicine's UCAR-T products come from young healthy donors. Their activity is far superior to that of long-term blood disease patients' own immune cells, and they have excellent expansion potential and persistence after reinfusion. In the IIT research in the early stage of the product, BRL Medicine's UCAR-T showed a significant and durable tumor clearance ability, and quickly achieved complete remission of the disease.

It can be said that the new generation of UCAR-T products of BRL Medicine solves the pain points and difficulties of the CAR-T treatment industry, and realizes the comprehensive improvement of curative effect, safety and clinical accessibility. It has very significant industrialization advantages, and its excellent Excellent clinical safety, therapeutic effect and extremely low production cost can enable more tumor patients to fully enjoy the dividends brought by the high technology of CAR-T therapy. In the future, BRL Medicine will also fully promote the clinical transformation and application of UCAR-T in the treatment of autoimmune diseases and solid tumors, so as to bring better treatment options to patients.
