Exanta (ximelagatran) receives first approval

PublishPublishEXANTA (XIMELAGATRAN) RECEIVES FIRST APPROVAL First indication for prevention of venous thromboembolic events in major orthopaedic surgery AstraZeneca has received its first regulatory approval for ExantaTM (ximelagatran) in France for the prevention of venous thromboembolic events in major orthopaedic (hip or knee replacement) surgery. France is the Reference Member State for the European Union (EU) Mutual Recognition Procedure for Exanta. Subject to approval, launches of Exanta in this first 'proof of principle' indication are expected to take place later in 2004. Exanta is the first oral treatment in a new World Health Organisation class of direct thrombin inhibitors (DTIs) and is the first new oral anticoagulant approved since the introduction of warfarin almost 60 years ago. Exanta benefits from administration as a fixed oral dose, has a rapid onset and offset of action and shows low potential for food and drug interactions. Importantly, coagulation monitoring is also not necessary in treatment with Exanta. The approval of Exanta for this first indication in France is based on the METHRO study programme, involving an early postoperative start of Exanta treatment, with initial injectable dosing administered at least four hours after the completion of surgery, followed by oral Exanta 24mg twice daily for up to 11 days. This approval reflects clinical practice that is becoming increasingly common in Europe and allows use in conjunction with spinal anaesthesia with the oral dosing route enabling treatment to be easily continued following discharge from hospital. More than half of patients undergoing major orthopaedic surgery develop VTE in the absence of preventative anticoagulant treatment, and while effective treatments are available, no treatment regimen to date has successfully balanced efficacy and bleeding risk with oral dosing. Regulatory submissions for prevention of stroke in atrial fibrillation and treatment of VTE, have already been filed in France as part of the EU Mutual Recognition Procedure. In the US, the Food and Drug Administration (FDA) submissions for use of Exanta in stroke prevention in patients with atrial fibrillation and long-term secondary prevention of VTE have also been filed alongside the orthopaedic surgery file for use of Exanta in prevention of VTE in total knee replacement. "Exanta offers a fundamentally new approach to prevention of thrombosis, one of the largest causes of morbidity and mortality in the western world", commented Dr Hamish Cameron, Vice President, Head of Exanta, AstraZeneca. "We are very pleased to announce this approval as the first step in introducing this innovative new anticoagulant to patients." Thrombosis leads to the occlusion of blood vessels and prevents the circulation of blood to the heart (myocardial infarction) and brain (stroke). When blood clots break away, they can lead to thromboembolism in the lungs (pulmonary embolism), limbs (deep vein thrombosis) or within any blood vessels (venous thrombosis). Each year, nearly four million people experience thrombosis worldwide and those at greatest risk include people with atrial fibrillation, those who have experienced a previous cardiac event such as a myocardial infarction, and patients following orthopaedic surgery (OS: total hip or knee replacement surgery). Although existing treatments are effective, they have many limitations. Several require subcutaneous or intravenous administration, whilst current oral treatments are limited by risk of drug and food interactions, the need for regular coagulation monitoring and dose titration.
