Acquired Hemophilia A Clinical Trial
Official title:
Emicizumab in Patients With Acquired Hemophilia A: Multicenter, Single-arm, Open-label Clinical Trial
This is a phase II multicenter open-label, single-arm prospective study to evaluate the efficacy of prophylactic emicizumab administered on a scheduled basis to prevent bleeds in patients with acquired hemophilia A (AHA).
Patients with AHA who are eligible will receive two loading doses of the study drug, emicizumab (6mg/kg on day 1 and 3 mg/kg on day 2) followed by once weekly subcutaneous emicizumab (1.5 mg/kg). Immunosuppression will be given concurrently as per investigator discretion. The primary endpoint (bleed rate) will be assessed after 12 weeks on study drug. If partial remission of the AHA has not been achieved, an additional 12 weeks of study drug may be given. A historical cohort and a study conducted in parallel in Germany (NCT04188639) will serve as control groups for evaluation of secondary endpoints provided the study cohort are comparable. ;
