Tests treatment safety and results for Hemophilia A
Official title SAFE Study: Safety of aPCC Following Emicizumab Prophylaxis
ClinicalTrials.gov ID: NCT04563520
What this study is testing
What is Emicizumab?
Emicizumab is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for hemophilia a.
Also referred to as ACE910, Hemlibra and RO5534262.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The purpose of the aPCC-emicizumab safety study is to investigate the hemostatic efficacy as measured by thrombin generation, of a low personalized dose of aPCC (FEIBA) in children and adults with hemophilia A and inhibitors on emicizumab prophylaxis.
- Phase 3: a large, late-stage study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 6 and older
You may be able to join if
- Moderately severe hemophilia A, defined as FVIII level \<0.05 IU/mL before development of an inhibitor
- Age ≥6 years of age at time of informed consent
- Documented on 2 occasions a high titer inhibitor (\>5 BU/mL) with a 72-hour washout within 2 years of enrollment
- Parent/guardian (Legally Authorized Representative) or the patient has provided written informed consent
- Adequate hematologic function (Hgb \>8 g/dL and platelet count \>100,000 µL)
You likely can't join if
- Inherited or acquired bleeding disorder other than hemophilia A excluding low VWF (\>30% VWF:RCo or VWF:GP1bm)
- Had an active bleed requiring factor therapy at screening
- Previous or current treatment for thromboembolic disease or signs of thromboembolic disease (excluding previously resolved line-associated thrombosis)
- Had a surgical procedure 14 days before screening
- Conditions that may increase the risk of bleeding or thrombosis
- If the patient is treated with rFVIIa or aPCC seven days before screening

- Participants who are at high risk for TMA (for example, have a previous medical/family history of TMA), in the investigator's judgment
- Concurrent disease, treatment, or abnormality in clinical laboratory tests that could interfere with the conduct of the study, may pose an additional risk, or would, in the opinion of the investigator, preclude the...
