-- Orphan drug designation provides marketing exclusivity if approved by FDA --
SOUTH SAN FRANCISCO, Calif., Sept. 26, 2017 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (Nasdaq:CBIO) today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation (ODD) for CB 2679d/ISU304, Catalyst’s highly potent subcutaneous next-generation recombinant human Factor IX variant, for the treatment of hemophilia B.
“Receipt of FDA orphan status will support the development of this promising subcutaneous treatment option for individuals with hemophilia B. Notable benefits of ODD include the potential for seven years of market exclusivity,” said Nassim Usman, Ph.D., President and Chief Executive Officer of Catalyst. “Assuming our ongoing clinical development program is successful, this important designation will bolster the rapid availability of CB 2679d for subcutaneous prophylaxis in this life-threatening and chronically debilitating disorder.”
In June 2017, the Company announced that the European Commission had also granted orphan medicinal product designation to CB 2679d for hemophilia B. Catalyst and its collaborator, ISU Abxis, are evaluating CB 2679d in a Phase 1/2 proof-of-concept study in individuals with severe hemophilia B. The Companies plan to have interim, top-line results by the end of 2017 and complete trial results in early 2018.
About Orphan Designation
Orphan drug designation is granted by the FDA to drugs and biologics that are defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases/disorders that affect fewer than 200,000 people in the U.S. Orphan drug designation provides certain incentives which may include tax credits towards the cost of clinical trials and prescription drug user fee waivers. If a product that has orphan drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan product exclusivity.
About Factor IX
CB 2679d is a next-generation high-potency coagulation Factor IX variant that is being evaluated in a Phase 1/2 proof-of-concept clinical trial in South Korea. Catalyst believes that CB 2679d may allow for subcutaneous prophylactic treatment of individuals with hemophilia B. Learn more about Factor IX.
