Trial Outcomes & Findings for Study Evaluating B-Domain Deleted Recombinant Factor VIII (BDDrFVIII, ReFacto AF) in Patients With Hemophilia A Undergoing Elective Major Surgery (NCT NCT00243659)

NCT ID: NCT00243659

Last Updated: 2011-06-03

Results Overview

Efficacy at the end of surgery as determined by the investigator and/or the surgeon using the 4 point ordinal scale (Excellent, Good, Moderate or None). Excellent: Achieved hemostatic comparable to non-hemophilic patients. Good: Prolonged time to hemostasis (with somewhat increased bleeding compared to non-hemophilic patients.
