SOUTH SAN FRANCISCO, Calif., Nov. 07, 2019 (GLOBE NEWSWIRE) -- Catalyst Biosciences, Inc. (NASDAQ: CBIO) today announced its operating and financial results for the third quarter ended September 30, 2019 and provided a corporate update.

“We continued to make progress in both the marzeptacog alfa (activated) (MarzAA – FVIIa) and dalcinonacog alfa (DalcA – FIX) clinical programs,” said Nassim Usman, Ph.D., president and chief executive officer of Catalyst. “We presented final MarzAA Phase 2 clinical data that clearly demonstrated the potential for subcutaneously (SQ) dosed MarzAA as a prophylactic treatment for hemophilia A or B patients with inhibitors.

In the DalcA Phase 2b trial, we successfully completed dosing in two subjects, achieving high FIX activity levels with a long SQ half-life without eliciting anti-drug antibodies (ADAs).”
