screening and prior to dosing and through 48 hours post dosing. At screening this
includes a washout of FIX for 96 hours and FVIII for 72 houts. At dosing this includes
a washout of FIX for 96 hours and FVIII and other hemostatic agents for 72 hours
through 48 hours post dosing.

- Subjects must agree and commit to using a a highly effective method of birth control
from the time of screening through four weeks after study drug administration.
Minimum age
18 Years
Maximum age
64 Years

Key exclusion criteria
- Presence of a bleeding disorder in addition to hemophilia A or B.

- Regular, concomitant therapy with immunomodulating drugs (eg, intravenous
immunoglobulin, and routine systemic corticosteroids).

- History of coronary artery disease, thrombolic disease or diagnosis of prothrombic
disorder.

Summary
Brief summary
This study hypothesizes that the study drug, PF-05280602 (at the selected doses) will be safe
to administer to subjects with severe Hemophilia A or B with or without inhibitors and will
demonstrate evidence of hemostatic activity. This is supported by the preclinical findings in
hemophilic animal models.
