Patients with hereditary antithrombin deficiency are at increased risk of venous thrombosis and pulmonary embolism, particularly during certain high risk procedures. The trial focused on patients with confirmed hereditary antithrombin deficiency who were undergoing a surgical procedure or induced/spontaneous labor and delivery, and/or caesarean section. The study assessed the incidence of thromboembolic events following prophylactic intravenous administration of recombinant human antithrombin (rhAT) to patients with hereditary antithrombin (AT) deficiency in situations usually associated with a high risk for thromboembolic events.
Name: Recombinant human antithrombin (rhAT)
Description: To assess the incidence of thromboembolic events acute deep venous thrombosis (DVT) and/or thromboembolic events other than acute deep venous thrombosis (DVT) by clinical signs and symptoms of venous thromboembolism (VTE), confirmed by diagnostic assessments.Measure: Incidence of Thromboembolic Events Acute Deep Venous Thrombosis (DVT) and/or Thromboembolic Events Other Than Acute Deep Venous Thrombosis (DVT) Time: During treatment and follow up period of 7 days
Single Group Assignment
There is one SNP

In September 2006, GTC Biotherapeutics modified exclusion criteria 1 (below) to allow for the participation of previously excluded patients with the hereditary thrombophilic disorders Factor V Leiden and prothrombin gene mutation (G20210A). --- G20210A ---
