Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.
