PCC treatment for hemophilia A patients with inhibitors

Official title: A Multicenter, Prospective, Single-arm Exploratory Study of Prothrombin Complex Concentrate in the Treatment of Bleeding Episodes in Patients With Hemophilia A With Inhibitors

Run by Institute of Hematology & Blood Diseases Hospital, China · NCT07406139 · Data updated 2026-11-12

This trial tests whether giving prothrombin complex concentrate (PCC) during bleeding episodes can stop bleeds in people aged 12–65 with hemophilia A who have inhibitors.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people aged 12–65 with diagnosed hemophilia A and inhibitors who have had at least three joint bleeds in the past six months and can give informed consent.

Probably not a fit

Patients with other bleeding disorders, significant liver or kidney impairment, active immune tolerance induction with low-titer inhibitors, a history of thrombosis, or relevant allergies are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, prospective, single-arm study that gives on-demand PCC to patients with hemophilia A and inhibitors during bleeding episodes. Dosing was guided by investigators with a recommended 50 IU/kg per infusion every 8–12 hours and a maximum total daily dose of 150 IU/kg. If bleeding was not controlled within 24 hours, investigators could add other hemostatic agents or switch treatments. Safety and hemostatic effectiveness were recorded across participating centers.

Why it matters

Potential benefit: If successful, PCC could provide an effective on-demand option to stop bleeding in patients with inhibitors when standard factor VIII replacement does not work.

How similar studies have gone: Bypassing agents such as activated PCC (aPCC) and recombinant activated factor VII (rFVIIa) have achieved >80% hemostatic success in prior studies, so the general bypassing approach has established efficacy though formulations and availability vary.
