Harry R. B\u00fcller, MD, University of Amsterdam, Amsterdam, The Netherlands, presented data from the Comparative Investigation of Edoxaban Tosylate (DU176b) Versus Warfarin in the Treatment of Symptomatic Deep-Vein Clots and\/or Lung Blood Clots trial [Edoxaban Hokusai-VTE Study; B\u00fcller HR et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013].\u003C\/p\u003E\u003Cp id=\u0022p-3\u0022\u003EThe third most frequent cardiovascular disease, VTE is estimated to affect about 700,000 North Americans annually [White RH. \u003Cem\u003ECirculation\u003C\/em\u003E 2003]. The traditional therapy for VTE, initial treatment with heparin followed by vitamin K antagonists [Kearon C et al. \u003Cem\u003EChest\u003C\/em\u003E 2012], has been challenged by several novel oral anticoagulants which have been studied either as monotherapy or after initial treatment with heparin in the treatment of VTE [Schulman S et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2009; EINSTEIN Investigators. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2010, 2012; Agnelli G et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013]. The Edoxaban Hokusai-VTE Study tested the hypothesis that treatment with edoxaban would be noninferior to warfarin after acute therapy with heparin in patients presenting with acute VTE.\u003C\/p\u003E\u003Cp id=\u0022p-4\u0022\u003EThe international Phase 3 Edoxaban Hokusai-VTE trial randomized 8240 patients with acute symptomatic deep-vein thrombosis (DVT) or pulmonary embolism (PE) to receive 60 mg daily edoxaban or warfarin with a target INR of 2\u20133. Those patients with a creatinine clearance of 30 to 50 mL\/min, body weight of \u0026lt;60 kg, or those patients treated with potent P-glycoprotein inhibitors randomized to edoxaban received a reduced dose of 30 mg daily. The duration of therapy was left to the treating physician and ranged from 3 to 12 months [B\u00fcller HR et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013]. Patients were eligible if they were aged \u226518 years, and were diagnosed with either an acute and symptomatic DVT in the popliteal, femoral, or iliac veins, or an acute and symptomatic PE. All patients were initially treated with low molecular weight or unfractionated heparin for at least 5 days. Blinded treatment allocation was maintained through the use of a point-of-care device for INR measurement in all patients that provided sham values for patients who were randomized to edoxaban.\u003C\/p\u003E\u003Cp id=\u0022p-5\u0022\u003EThe mean age of trial participants was 56 years and 57% were male. Overall, 4921 patients had DVT and 3391 patients had PE. The 30-mg dose of edoxaban was administered to 18% and 17% of patients in the edoxaban and warfarin arms, respectively. Patients in the warfarin arm had a mean time in the therapeutic window of 63.5%. Approximately 40% of patients were treated for 12 months.\u003C\/p\u003E\u003Cp id=\u0022p-6\u0022\u003EThe primary efficacy endpoint was recurrent symptomatic VTE (either DVT or PE). The efficacy analyses were performed in a modified intention-to-treat population consisting of all patients randomized who received at least one dose of the study drug. The upper confidence interval for noninferiority was 1.5. The primary safety endpoint was a composite of clinically relevant major and non-major bleeding.\u003C\/p\u003E\u003Cp id=\u0022p-7\u0022\u003ERates of recurrent VTE were similar with edoxaban compared with warfarin (3.2% vs 3.5%; HR, 0.89; 95% CI, 0.70 to 1.13; p\u0026lt;0.001 for noninferiority) [B\u00fcller HR et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013]. Similar results were found when limiting the analysis to events which occurred while on treatment (HR, 0.82; 95% CI, 0.60 to 1.14; p\u0026lt;0.001 for noninferiority). In a subgroup of patients with evidence of severe PE (evidence of right ventricular dysfunction or elevated natriuretic peptides), edoxaban reduced recurrent VTE (HR, 0.52; 95%\nCI, 0.28 to 0.98).\u003C\/p\u003E\u003Cp id=\u0022p-8\u0022\u003ERates of clinically relevant bleeding (major or nonmajor) were lower with edoxaban compared with warfarin (8.5% vs 10.3%; HR, 0.81; 95% CI, 0.71 to 0.94; p=0.004) [B\u00fcller HR et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013]. Major bleeding was similar with edoxaban compared with warfarin (1.4% vs 1.6%; HR, 0.84, 95% CI, 0.59 to 1.21; p=0.35).\u003C\/p\u003E\u003Cp id=\u0022p-9\u0022\u003EProf. B\u00fcller concluded by noting that the Edoxaban Hokusai-VTE Study confirmed the hypothesis that in patients with acute VTE treated initially with heparin, treatment with edoxaban is noninferior to warfarin for the prevention of recurrent VTE. In addition, he highlighted that edoxaban had similar efficacy as warfarin but did have a lower rate of clinically relevant bleeding and a similar rate of major bleeding when compared with warfarin.\u003C\/p\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2013 MD Conference Express\u00ae\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/13\/15\/11.2.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nznmm2\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
