Study Evaluating On-Demand Treatment Of Xyntha In Chinese Subjects
An Evaluation Of The Safety And Efficacy Of On-Demand Treatment With Xyntha (B Domain Deleted Recombinant Factor VIII, Albumin Free) In Chinese Subjects With Hemophilia A
This study will evaluate the safety and efficacy of on-demand treatment with Xyntha in Chinese hemophilia A subjects.

Interventional
Phase 3
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Hemophilia A
Biological: Xyntha
Xyntha for on-demand treatment of bleeding episodes were according to investigator prescription during the 6 months observation period. The recovery assessed by determining the Factor VIII (FVIII) concentration (FVIII:C) levels in individual subjects at the initial and final visits. The dose of Xyntha for recovery assessments is: single 50 IU/kg (±5 IU/kg) IV bolus infusion. All Xyntha administrations occurred in the clinic (hospital).
Experimental: Xyntha
This trial was an open-label and included assessments of safety, clinical efficacy, and Factor VIII (FVIII) recovery in Chinese subjects with hemophilia A. Subjects received on-demand treatments with Xyntha over a 6-month (calendar day) period.
Intervention: Biological: Xyntha
