SOUTH SAN FRANCISCO, Calif., July 06, 2017 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (Nasdaq: CBIO ), a clinical-stage biopharmaceutical company focused on developing novel medicines to address hematology indications, today announced that it has achieved a financial milestone under its collaboration with ISU Abxis. In June of 2017, the first patient and cohort were enrolled in a Phase 1/2 proof-of-concept clinical trial in individuals with severe hemophilia B, which triggered the milestone payment to Catalyst. The clinical trial will evaluate Catalyst’s next-generation Factor IX variant, CB 2679d/ISU304, for subcutaneous prophylaxis. ISU Abxis and Catalyst plan to have top-line data from the clinical trial by the end of 2017.
As previously announced, ISU Abxis has completed dosing of the first cohort of up to five patient cohorts in the clinical trial. The trial will include single intravenous and subcutaneous dosing cohorts, followed by daily subcutaneous injections of CB 2679d/ISU304.
“We are pleased to have achieved another financial milestone with the Factor IX clinical program, but for us the highlight of the Factor IX program has been the rapid patient enrollment in the clinical trial to date,” said Nassim Usman, Ph.D., President and Chief Executive Officer of Catalyst. “We want to prevent bleeding in individuals with hemophilia B and we look forward to results later this year that may determine whether CB 2679d/ISU304 can achieve sustained normalization of Factor IX activity with subcutaneous dosing.”
Catalyst has a collaboration with ISU Abxis to advance the development of CB 2679d/ISU304 through the Phase 1/2 proof-of-concept clinical trial in individuals with 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.
