Hemophilia A Clinical Trial
Official title:
AN OPEN-LABEL, NON-INVESTIGATIONAL PRODUCT, MULTI-CENTER, LEAD-IN STUDY TO EVALUATE PROSPECTIVE EFFICACY AND SAFETY DATA OF FACTOR IX OR FACTOR VIII PROPHYLAXIS REPLACEMENT THERAPY IN THE USUAL CARE SETTING OF MODERATELY SEVERE TO SEVERE ADULT HEMOPHILIA B SUBJECTS (FIX:C≤2%) WHO ARE NEGATIVE FOR NEUTRALIZING nAb TO AAV VECTOR-SPARK100 AND MODERATELY SEVERE TO SEVERE HEMOPHILIA A ADULT SUBJECTS (FVIII:C≤1%) WHO ARE NEGATIVE FOR nAb TO AAV VECTOR SB-525 CAPSID (AAV6), PRIOR TO THE RESPECTIVE THERAPEUTIC PH 3 GENE THERAPY STUDIES (See Detailed Description Section for Official Protocol Title)
To establish baseline prospective efficacy data of current FIX prophylaxis replacement therapy in the usual care setting of hemophilia B subjects, who are negative for nAb to AAV-Spark100, prior to the Phase 3 gene therapy study. To establish baseline prospective efficacy data of current FVIII prophylaxis replacement therapy in the usual care setting of hemophilia A subjects, who are negative for nAb to AAV6, prior to the Phase 3 gene therapy study. The enrollment for hemophilia A participants is completed. At this time participants are only being enrolled for hemophilia B cohort.
