Catalyst Biosciences Receives FDA Fast Track Designation for Subcutaneous MarzAA for the
Treatment of Episodic Bleeding in Hemophilia A or B with Inhibitors
SOUTH SAN FRANCISCO, Calif. – Dec. 2, 2020 – Catalyst Biosciences, Inc. (NASDAQ: CBIO) today announced the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for Marzeptacog alfa (activated) – or MarzAA, the Company’s subcutaneously (SQ) administered next-generation engineered coagulation Factor VIIa (FVIIa) for the treatment of episodic bleeding in subjects with Hemophilia A or B with inhibitors that will enter a pivotal Phase 3 study CRIMSON 1 this month.
The Fast Track program is designed to facilitate and expedite the development and review of drug candidates that have demonstrated the potential to address an unmet medical need in treating serious diseases or conditions. A drug candidate with Fast Track designation is eligible for greater access to the FDA as well as a priority review and rolling review of the marketing application.
“We believe the FDA Fast Track Designation validates MarzAA’s potential to improve patient care. As the only SQ delivered therapy in development for on-demand treatment of bleeding events, MarzAA is uniquely positioned to become an important addition to the treatment landscape.” said Nassim Usman, Ph.D., president and chief executive officer of Catalyst.
The Phase 3 CRIMSON 1 study is an open-label, global, multi-center, randomized, cross-over study, designed to evaluate the safety and efficacy of MarzAA for on-demand treatment of spontaneous or traumatic bleeding episodes, in adolescents and adults with congenital Hemophilia A or B with inhibitors, compared to the Standard of Care. The study will enroll approximately 60 subjects to treat 244 eligible bleeding episodes with each treatment. The primary endpoint for the trial is the percentage of treated bleeds resulting in effective hemostasis at the 24-hour timepoint. The objective of the trial is to demonstrate non-inferiority of MarzAA compared with Standard of Care.
About Catalyst Biosciences
Catalyst is a research and clinical development biopharmaceutical company focused on addressing unmet medical needs in rare hematologic and complement-mediated disorders. Our protease engineering platform has generated two late-stage clinical programs in hemophilia; a research program on engineering of subcutaneous (SQ) complement inhibitors; a discovery stage Factor IX gene therapy construct—CB 2679d-GT—for Hemophilia B, and a partnered preclinical development program with Biogen for dry age-related macular degeneration (AMD). The product candidates generated by our protease engineering platform have improved functionality and potency that allow for: SQ administration of recombinant coagulation factors and complement inhibitors; low-dose, high activity gene therapy constructs; and less frequently dosed intravitreal therapeutics.
Forward-Looking Statements
This press release contains forward-looking statements that involve substantial risks and uncertainties. Forward-looking statements include statements about Catalyst’s plans for a Phase 3 study of MarzAA for on-demand treatment of spontaneous or traumatic bleeding episodes, the potential for MarzAA to effectively and therapeutically treat hemophilia subcutaneously, the potential benefits of Fast Track Designation, and the Company’s collaboration with Biogen for the development and commercialization of pegylated CB 2782 for the potential treatment of geographic atrophy-associated dry age-related macular degeneration. Actual results or events could differ materially from the plans, intentions, expectations and projections disclosed in the forward-looking statements. Various important factors could cause actual results or events to differ materially, including, but not limited to, the risk that trials and studies may be

delayed as a result of COVID-19 and other factors, that trials may not have satisfactory outcomes, that additional human trials will not replicate the results from earlier trials, that potential adverse effects may arise from the testing or use of MarzAA, including the generation of neutralizing antibodies, the risk that costs required to develop or manufacture the Company’s products will be higher than anticipated, including as a result of delays in development and manufacturing resulting from COVID-19 and other factors, the risk that Biogen will terminate Catalyst’s agreement, competition and other risks described in the “Risk Factors” section of the Company’s quarterly report filed with the Securities and Exchange Commission on November 5, 2020, and in other filings with the Securities and Exchange Commission.
