The Breakthrough Designation for CNCT19 was granted based on initial data from the ongoing single arm, open-label, non-randomized, dose-escalation, Phase I study designed to determine the safety and efficacy of CNCT19 in B-ALL.

The Breakthrough Designation procedure is part of the recently revised Drug Registration Regulation which went into effect on July 1, 2020. The Breakthrough Designation process is designed to expedite the development and review of therapies that are intended for treatment of serious diseases for which there is no existing treatment and where preliminary evidence indicates advantages of the therapy over available treatment options.

Dr. Wei-Wu He, CASI’s Chairman, and CEO commented, "Our partner Juventas continues to make encouraging progress in developing their CD19 CAR-T therapy. Breakthrough Designation represents a significant regulatory milestone and has only been granted thirteen times in China. Receiving Breakthrough Designation is a very encouraging and important step forward for patients suffering from B-ALL."

About CNCT19

CNCT19 targets CD19, a B-cell surface protein widely expressed during all phases of B-cell development and a validated target for B-cell driven hematological malignancies. CD19- targeted CAR constructs from several different institutions have demonstrated consistently high antitumor efficacy in children and adults with relapsed B-cell acute lymphoblastic leukemia (B-ALL), chronic lymphocytic leukemia (CLL), and B-cell non-Hodgkin lymphoma (B-NHL). CD19 antigen is the most frequently used target in the CAR-T cell therapy clinical trials for hematological malignancies such as leukemia and lymphoma. Juventas is responsible for the development of CNCT19. CASI and Juventas will co-commercialize CNCT19 under the direction of the program’s joint steering committee.
