5 months ago

SOUTH SAN FRANCISCO, Calif., Feb. 16, 2017 (GLOBE NEWSWIRE) — Catalyst Biosciences, Inc., (CBIO) a clinical-stage biopharmaceutical company focused on developing novel medicines to address hematology indications, today announced that Andrew Hetherington has been promoted to Senior Vice President of Technical Operations. Mr. Hetherington joined Catalyst in September 2015 and has successfully led the Pfizer-to-Catalyst technology transfer of the Company’s next-generation Factor VIIa clinical candidate, and has been instrumental in advancing the Company’s next generation Factor IX clinical manufacture and associated program activities.

“Andrew’s significant contributions to our manufacturing initiatives, especially establishing our ability to manufacture marzeptacog alfa (activated), our next-generation Factor VIIa, at commercial scale has been critical to our plan to commence a subcutaneous efficacy trial of marzeptacog alfa (activated) in individuals with hemophilia B with inhibitors in 2017,” said Nassim Usman, Ph.D., President and Chief Executive Officer of Catalyst.

Catalyst is focused on the prevention of bleeding in individuals with hemophilia through the development of clotting factors that may be injected subcutaneously to potentially achieve normal coagulation activity. The Company plans to initiate a subcutaneous efficacy trial of marzeptacog alfa (activated), a next-generation Factor VIIa, in individuals with hemophilia B with inhibitors in 2017. In addition, in the second quarter of 2017, Catalyst and its collaboration partner, ISU Abxis, plan to initiate a Phase 1/2 proof-of-concept clinical trial of CB 2679d/ISU304, a next-generation coagulation Factor IX, in individuals with hemophilia B that includes single and multiple subcutaneous dose regimens.

About Factor VIIa
Marzeptacog alfa (activated) is a high potency next-generation Factor VIIa that successfully completed an intravenous Phase 1 clinical trial in severe hemophilia A and B patients with and without inhibitors. Marzeptacog alfa (activated) is initially being developed for the subcutaneous prophylactic treatment of severe hemophilia B patients with inhibitors. Preclinical studies of Marzeptacog alfa (activated) have demonstrated efficacy and good subcutaneous pharmacokinetic/pharmacodynamic properties in several models that support subcutaneous dosing in clinical trials.

About Factor IX
CB 2679d/ISU304 is a high potency next-generation coagulation Factor IX variant that is in advanced preclinical development. CB 2679d/ISU304 has exhibited enhanced procoagulant activity, improved efficacy in inhibiting blood loss, and prolonged duration of action in bleeding and non-bleeding preclinical models compared with other Factor IX products and has recently shown good subcutaneous dosing properties in preclinical models. Catalyst believes that CB 2679d/ISU304 may allow for subcutaneous prophylactic treatment of individuals with hemophilia B. 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 hemophilia B. After Phase 1/2, ISU Abxis has an option for exclusive commercial rights in South Korea while Catalyst retains full development and commercial rights for CB 2679d/ISU304 outside of South Korea.

About Hemophilia and Factor Replacement Therapy
Hemophilia, for which there is no cure, is a rare but serious bleeding disorder that results from a genetic or an acquired deficiency of a protein required for normal blood coagulation. There are two major types of hemophilia, A and B, that are caused by alterations in Factor VIII or Factor IX genes, respectively, with a corresponding deficiency in the affected proteins. The prevalence of hemophilia A and B in the United States is estimated to be around 20,000 people, with more than 400,000 cases worldwide. Individuals with hemophilia suffer from spontaneous bleeding episodes as well as substantially prolonged bleeding times upon injury. In cases of severe hemophilia, spontaneous bleeding into muscles or joints is frequent and often results in permanent, disabling joint damage and can become life threatening. Treatment usually involves management of acute bleeding episodes or prophylaxis through factor replacement therapy by intravenous infusion of patients’ missing Factor VIII or IX. With the frequent infusion schedule of current therapies, adherence is difficult. In addition, convenient access to peripheral veins is often a problem, and many children require use of central venous access devices, with the concomitant risks of infection and thrombosis.
