Although the mean population age and the gross inclusion and exclusion criteria were similar across these studies, they differed in other aspects such as overall study design and acute treatment strategies. The 4 DOACs examined in phase III trials (apixaban, edoxaban, rivaroxaban, and dabigatran) showed noninferiority compared with standard therapy for the treatment of deep vein thrombosis and\/or pulmonary embolism and for the prevention of recurrent venous thromboembolism. Furthermore, these DOACs exhibited a similar safety profile to standard therapy, with the risk of major bleeding significantly reduced in some of these studies. Rivaroxaban and apixaban were tested as a single-drug approach, whereas in the dabigatran and edoxaban studies, initial bridging with parenteral agents was employed. The purpose of this review is to compare the phase III studies of DOACs in this indication, to highlight the differences, and to discuss a series of clinically relevant issues, including the management of key patient subgroups (eg, fragile patients, those with cancer or renal impairment), extended treatment, use of comedications, heparin pretreatment versus a single-drug approach, and the bleeding profiles of the DOACs.<\/jats:p>","DOI":"10.1177\/1076029615600791","type":"journal-article","created":{"date-parts":[[2015,9,1]],"date-time":"2015-09-01T19:57:59Z","timestamp":1441137479000},"page":"209-221","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Direct Oral Anticoagulants and Their Use in Treatment and Secondary Prevention of Acute Symptomatic Venous Thromboembolism"],"prefix":"10.1177","volume":"22","author":[{"given":"Serena","family":"Granziera","sequence":"first","affiliation":[{"name":"Vascular Medicine, King\u2019s College Hospital, London, United Kingdom"},{"name":"Department of Medicine\u2014DIMED, University of Padova, Padova, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arjumand","family":"Hasan","sequence":"additional","affiliation":[{"name":"Geriatric Medicine, Kingston Hospital, Surrey, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander (Ander) T.","family":"Cohen","sequence":"additional","affiliation":[{"name":"Department of Haematological Medicine, Guys and St Thomas\u2019 NHS Foundation Trust, King\u2019s College London, London, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,8,31]]},"reference":[{"key":"bibr1-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1160\/TH04-05-0323"},{"issue":"4","key":"bibr2-1076029615600791","first-page":"756","volume":"98","author":"Cohen AT","year":"2007","journal-title":"Thromb Haemost"},{"key":"bibr3-1076029615600791","doi-asserted-by":"publisher","DOI":"10.2146\/ajhp060388"},{"key":"bibr4-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1378\/chest.11-2301"},{"key":"bibr5-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehu283"},{"key":"bibr6-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.164.10.1077"},{"key":"bibr7-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1378\/chest.08-0670"},{"key":"bibr8-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1302507"},{"key":"bibr9-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1306638"},{"key":"bibr10-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1007903"},{"key":"bibr11-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1113572"},{"key":"bibr12-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0906598"},{"key":"bibr13-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.113.004450"},{"key":"bibr14-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1207541"},{"key":"bibr15-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1113697"},{"key":"bibr16-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1007\/s12325-013-0041-4"},{"key":"bibr17-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1111\/j.1538-7836.2008.02835.x"},{"key":"bibr18-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.158.6.585"},{"key":"bibr19-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1186\/1477-9560-11-21"},{"key":"bibr20-1076029615600791","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.10516"},{"key":"bibr21-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2013-10-512616"},{"key":"bibr22-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1111\/j.1538-7836.2007.02468.x"},{"key":"bibr23-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2002-01-0108"},{"key":"bibr24-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.10847"},{"key":"bibr25-1076029615600791","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-125-1-199607010-00001"},{"key":"bibr26-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199205073261902"},{"key":"bibr27-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjmed.2007.08.011"},{"key":"bibr28-1076029615600791","doi-asserted-by":"publisher","DOI":"10.1016\/S1701-2163(16)34240-2"},{"key":"bibr29-1076029615600791","unstructured":"Boehringer Ingelheim International GmbH.
