Catalyst Biosciences gets OK for hemophilia med in S. Korea

March 28, 2017

Catalyst Biosciences, Inc. (Nasdaq: CBIO), a clinical-stage biopharmaceutical company focused on developing novel medicines to address hematology indications, today announced that the Korean Ministry of Food and Drug Safety (MFDS) approved the Investigational New Drug Application (IND) for CB 2679d/ISU304. Hemophilia is a serious bleeding disorder that results in spontaneous bleeding episodes as well as substantially prolonged bleeding times upon injury.

CB 2679d/ISU304, a highly potent next-generation coagulation Factor IX variant, has demonstrated the potential to normalize human Factor IX levels with a daily subcutaneous injection in preclinical studies. Catalyst’s collaborator, ISU Abxis (KOSDAQ:086890), plans to initiate a Phase 1/2 proof-of-concept study with single and multiple subcutaneous injections in individuals with severe hemophilia B in the second quarter of 2017.

“We are very pleased with the progress we and our collaborator ISU Abxis have made in advancing this Factor IX candidate towards the clinic and we look forward to the initiation of a Phase 1/2 clinical trial next quarter,” said Nassim Usman, Ph.D., President and Chief Executive Officer of Catalyst. “We believe that stopping bleeding is good, but preventing bleeding is better. CB 2679d/ISU304 has the properties required, including high potency, to allow for daily subcutaneous injection with the potential to achieve stable and normal Factor IX clotting levels.”

Catalyst has a collaboration with ISU Abxis to advance the development of CB 2679d/ISU304 through a Phase 1/2 proof-of-concept study in individuals with severe hemophilia B. After Phase 1/2, ISU Abxis has an option for exclusive commercial rights in South Korea and a profit share on ex-South Korean commercialization. Catalyst retains full development and commercial rights for CB 2679d/ISU304 outside of South Korea.
