  Purpose

The purpose of the study is to assess the efficacy and safety of Prothromplex Total as a treatment for the immediate reversal of oral anticoagulant therapy with vitamin K antagonists in patients with acquired deficiency of prothrombin complex coagulation factors (II, VII, IX, X). Upon enrolment, subjects will receive Prothromplex Total for the treatment of acute bleeding due to oral anticoagulants or for the prevention of excessive bleeding during the interventional procedure (Day 1). Additional doses of Prothromplex Total may be administered at the discretion of the investigator. Efficacy and safety assessments will be performed during a period of 72 (± 4) hours after administration of the last dose of Prothromplex Total or until discharge from hospital, whichever occurs first.

Primary Outcome Measures:
  • Proportion of subjects who achieve normalisation of International normalised ratio (INR) to <= 1.3 within 30 (±5) minutes post administration of Prothromplex Total [ Time Frame: within 35 minutes after administration of study drug ] [ Designated as safety issue: No ]

Enrollment: 61
Study Start Date: July 2010
Study Completion Date: June 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: Prothrombin complex concentrate (coagulation factors IX, II, VII and X in combination)
    Intravenous infusion; regimen is guided by the pre-treatment international normalised ratio (INR); dosage and duration of replacement therapy depend on the severity of the disorder, on the location and extent of bleeding and on the patient´s clinical condition.
