About Catalyst Biosciences

Catalyst is a clinical-stage biopharmaceutical company focused on addressing unmet needs in rare diseases and systemic complement mediated disorders. Our protease engineering platform includes development programs in hemophilia and a research program on subcutaneous (SQ) systemic complement inhibitors. Our engineered coagulation factors are designed to overcome the significant limitations of current IV treatment options, facilitate prophylaxis, and ultimately deliver substantially better outcomes for patients using SQ dosing. Our lead asset, MarzAA (FVIIa) has successfully completed Phase 2 development, reducing the annualized bleed rate (ABR) in individuals with hemophilia A or B with inhibitors by >90%. Our second hemophilia asset, DalcA (FIX) is completing a Phase 2b clinical trial for the prophylactic treatment of hemophilia B and has achieved FIX levels from 12-27%. We also have a global license and collaboration agreement with Biogen for the development and commercialization of pegylated CB 2782 (anti-C3 protease) for the potential treatment of geographic atrophy associated dry age-related macular degeneration.
