New study tests safer bleeding control for hemophilia a patients on emicizumab

NCT ID NCT04563520

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 3 study is testing whether a low, personalized dose of FEIBA (aPCC) can safely control bleeding in children and adults with hemophilia A who have inhibitors and are already taking emicizumab. The study will measure how well the blood clots after FEIBA is given and track any serious side effects. Only 5 participants are being enrolled, so results will be very preliminary.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Emicizumab (Hemlibra) and FEIBA (activated prothrombin complex concentrate)
What this could lead to
If successful, this could show that a low, personalized dose of FEIBA is safe and effective for managing breakthrough bleeding in people with hemophilia A and inhibitors who are already on emicizumab.
What could go wrong
This is a very small study (only 5 participants) and is still recruiting. It focuses on lab measures of clotting, not long-term outcomes, so results may not apply broadly. There is also a risk of blood clots or other serious side effects.
