CB 2679d demonstrated a 22-fold greater potency over BeneFIX and a longer mean residence time
SOUTH SAN FRANCISCO, Calif., Nov. 01, 2017 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (NASDAQ:CBIO), a clinical-stage biopharmaceutical company focused on developing novel medicines to address hematology indications, today announced an oral presentation, entitled “Phase I/2 Trial of Subcutaneously Administered Factor IX Variant CB 2679d/ISU304: Pharmacokinetics and Activity” authored by Chur Woo You, M.D., Ph.D., Eulji University Hospital, et al., will be presented by Dr. Howard Levy, chief medical officer of Catalyst at the 59th American Society of Hematology (ASH) Annual Meeting and Exposition being held Dec. 9-12, 2017 in Atlanta.
Dr. Levy will present interim pharmacokinetic and pharmacodynamic results from intravenous and subcutaneous dosing of several subjects from ISU Abxis Co., Ltd. (KOSDAQ:086890), and Catalyst’s ongoing Phase 1/2 trial of drug candidate CB 2679d/ISU304, a coagulation Factor IX (FIX) variant being developed for the subcutaneous treatment of hemophilia B. Results from the first cohort of patients in the trial demonstrated that CB 2679d has 22-fold greater potency than BeneFIX, the most commonly prescribed FIX treatment for hemophilia B, after a single intravenous dose. The data to date support the potential of achieving normal or mild hemophilia FIX levels in individuals with hemophilia B with repeated daily subcutaneous dosing.
“All current FIX treatments require intravenous administration and do not provide sustained normal or even mild FIX trough levels,” said Dr. Levy. “However, due to its subcutaneous administration route and potential to normalize FIX levels, CB 2679d is an exciting potential new prophylactic treatment option for individuals, especially children, with hemophilia B. We look forward to announcing our top-line results by Q1 of 2018.”
