Apixaban Discontinuation Prior to Major Surgery

2016-10-18 02:08:21 | BioPortfolio


The ADIOS study is a prospective, observational study will evaluate one hundred and thirty (130) patients with non-valvular atrial fibrillation who are currently receiving treatment with apixaban as indicated to reduce the risk of stroke or systemic embolism, and who require an elective major surgical or invasive procedure will be included in the study. The purpose of the study is to evaluate the efficacy of the recommended pre-procedure washout period of 48 hours.


This study will estimate for what proportion of patients a 48 hour pre-procedure apixaban discontinuation is sufficient to achieve minimal apixaban plasma levels (less than 30 ng/mL) prior to surgery. The investigators hypothesize that this portion will be 80-95%.

All patients will have a blood draw at 48 hours prior to procedure and then a second blood draw on the morning of the procedure to test apixaban plasma and anti-Xa levels. Patients will also receive a follow-up phone call at 30 days to collect information on clinical events.

Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.
