Can a protein replacement tame a rare Blood-Clotting disorder?

NCT ID NCT06590974

First seen Jul 31, 2026 · Last updated Jul 31, 2026

Summary

This study looks at how well a medicine called Ceprotin (TAK-662) works and how safe it is for people with congenital protein C deficiency, a rare inherited condition that raises the risk of dangerous blood clots. Participants receive the medicine through an IV as part of their usual care, and researchers track any side effects and how effective it is over up to 24 months. The goal is to gather real-world information on this treatment in everyday practice.

What this could mean

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

Active substance
Freeze-dried Human Protein C Concentrate (TAK-662) given by intravenous injection
What this could lead to
If successful, this could support the safe use of protein C concentrate to manage congenital protein C deficiency, potentially reducing the risk of dangerous blood clots.
What could go wrong
This is a small, observational study in Japan with only 7 participants, so results may not apply broadly. As with any blood product, there is a risk of allergic reactions or other adverse events.
