Tracking a bleeding disorder treatment in real-world use

This is a monitoring study of OBIZUR, a medication used to treat acquired hemophilia A—a rare bleeding disorder that develops in adults. The study will collect information from people in South Korea who are receiving this treatment, both from their past medical records and from ongoing follow-up visits. Researchers want to understand how well this medication works and how safe it is when used in real-world medical settings.

After a medication is approved and available to patients, companies need to keep watching how it performs in everyday use to make sure it remains safe and effective for the people who need it. This study helps gather that real-world evidence.
