Oral Dabigatran Etexilate Versus Enoxaparin for Prevention of Venous Thromboembolism After Total Hip or Knee Arthroplasty: A Pooled Analysis of Four Randomized Trials

Abstract Abstract 2312 Introduction: Thromboprophylaxis after major orthopaedic surgery reduces the risk of venous thromboembolism (VTE). Four randomized, double-blind, non-inferiority trials compared oral dabigatran etexilate doses of 220 mg or 150 mg once daily (qd) with subcutaneous enoxaparin for the primary prevention of VTE in patients undergoing elective total hip or knee arthroplasty. In the hip arthroplasty trials (RE-NOVATE® and RE-NOVATE® II) the treatment duration was 28–35 days; in the knee arthroplasty trials it was 6–10 days (RE-MODEL™) and 12–15 days (RE-MOBILIZE®). Three of the trials used a comparator enoxaparin regimen of 40 mg qd started the evening before surgery, while…
