NCT ID NCT04023019

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study follows 120 men with hemophilia A who have developed inhibitors (antibodies that block standard treatment). Researchers will observe how doctors manage their condition using different therapies, including immune tolerance induction and newer drugs like emicizumab. The goal is to see which approaches work best to lower inhibitor levels and reduce bleeding episodes over up to 5 years.
