AstraZeneca Submits Marketing Authorisation Application To European Union For Cardiovascular Drug Axanum

Friday, 4 June 2010 AstraZeneca announced today that it has submitted a Marketing Authorisation Application (MAA) in the European Union via the Decentralised Procedure (DCP) for a product combining low-dose ASA (acetylsalicylic acid) and the active ingredient of Nexium (esomeprazole) for the prevention of cardio- and cerebrovascular (CV) events in patients requiring continuous low-dose ASA treatment who are at risk of developing ASA-associated gastric and/or duodenal ulcers. Pending approval, the proposed trade name for the product is Axanum. Low-dose ASA, commonly known as aspirin, is a mainstay of therapy for patients at high risk of a CV event such as myocardial infarction or stroke. However, upper GI problems (including symptoms, ulcers and ulcer-related complications) are common reasons for discontinuing low-dose ASA therapy. Up to 30% of patients with upper GI problems discontinue or take deliberate breaks from their low-dose ASA treatment, which can place them at risk of a potentially life-threatening CV event as early as 8-10 days after discontinuation. Two phase III studies, ASTERIX and OBERON, including more than 3,400 patients, have demonstrated the clinical benefit of low-dose ASA plus esomeprazole compared to low-dose ASA plus placebo in patients who required low-dose ASA treatment and had an increased risk for ulcer development. ASTERIX reported that esomeprazole 20 mg once daily was significantly more effective compared to placebo in preventing gastric and/or duodenal ulcers and associated upper GI symptoms in this patient group. OBERON showed that acid-suppressive therapy with esomeprazole 20mg or 40mg given daily is effective in preventing the occurrence of gastric/duodenal ulcers as well as upper GI symptoms in patients at increased risk of ulcer development during low-dose ASA therapy.
