Daiichi Sankyo Company Ltd announced that the U.S. Food and Drug Administration (FDA) has approved savaysa (edoxaban) Tablets, an oral, once-daily selective factor Xa-inhibitor, to reduce the risk of stroke and systemic embolism (SE) in patients with non-valvular atrial fibrillation (NVAF). In ENGAGE AF-TIMI 48, savaysa was non-inferior to warfarin in the overall study population for the primary efficacy endpoint of stroke or SE.1 As stated in the U.S. label, savaysa should not be used in NVAF patients with creatinine clearance (CrCL) levels greater than 95 mL/min because in that population there is an increased risk of ischemic stroke compared to warfarin. Patients with CrCL less than or equal to 95 mL/min represented 77 percent of the patients studied. In those patients, savaysa 60 mg reduced the risk of stroke and SE when compared to warfarin, and the rates of cardiovascular death with savaysa and warfarin were 2.95 percent per year vs. 3.59 percent per year, respectively.1 The FDA also approved savaysa for the treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE) following 5-10 days of initial therapy with a parenteral anticoagulant.
“The approval of savaysa demonstrates our commitment to providing new treatment options for cardiovascular diseases with significant unmet needs and reinforces our leadership in factor Xa-inhibition research, which began more than 30 years ago,” said Joji Nakayama, representative director, President and Chief Executive Officer, Daiichi Sankyo. “We look forward to making savaysa available to patients in the U.S. with NVAF and venous thromboembolism, two serious conditions that are expected to double in prevalence by mid-century.”
“savaysa is an important new anticoagulant in the U.S. and in the ENGAGE AF-TIMI 48 trial, savaysa has been shown to reduce the risk of stroke and SE with significantly less major bleeding for patients with NVAF, and in the Hokusai-VTE trial, to treat DVT and PE with significantly less clinically relevant bleeding versus warfarin, the most commonly prescribed anticoagulant,” said Glenn Gormley, MD, PhD, Senior Executive Officer and Global Head of R&D, Daiichi Sankyo Company, Limited and Executive Chairman and President, Daiichi Sankyo, Inc. “In addition, savaysa offers the convenience of once-daily dosing, no need for routine blood monitoring and the flexibility to be taken with or without a meal.”
The approved indications in the U.S. for savaysa are based on data from the ENGAGE AF-TIMI 48 and Hokusai-VTE studies. The most common side effects observed in clinical trial participants were bleeding and anemia.1,2 savaysa increases the risk of bleeding and can cause serious and potentially fatal bleeding.
