The POBOY Study

This is the app for the Prevention Of Bleeding by Optimizing prophYlaxis study. Your use of the app creates a valuable record that may allow us to develop an optimal administration regimen for the prophylactic treatment of hemophilia and better understand what causes breakthrough bleeding.

Use the app to record and review your own daily activities, infusions, and bleeds. The app also allows you to easily keep up with your own care as well by allowing you to see what you've taken and when.

Quickly scan the boxes of your factor or other product to record when you take anti-hemophilic medications. The app supports automated scanning of many products that contain these clotting factors/medications:

• Clotting Factor VIII
• Clotting Factor IX
• Hemlibra
• Von Willebrand Factor
• Activated Factor VII
