Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 99 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 130 patients who are currently receiving treatment with apixaban for non-valvular atrial fibrillation and scheduled for an elective surgical procedure.

Who may be able to join

  • At least 18 years of age
  • On long term anticoagulation with apixaban for treatment of non-valvular atrial fibrillation or venous thromboembolism
  • Undergoing elective major surgery or invasive procedure

Who cannot join

  • Inability to obtain informed consent for the blood sample draws
  • Any condition precluding collection of follow-up information
  • Participation in another clinical trial
  • Apixaban Package Insert Recommendations and Cautions
  • Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of study drug.
  • Women must not be breastfeeding

  • WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug apixaban plus 5 half-lives of study drug apixaban (approximately 3 days) plus 30 days (duration of ovulatory cycle) for a total of 33 days post- treatment completion.
  • Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug apixaban plus 5 half-lives of the study drug (approximately 3 days) plus 90 days (duration of sperm turnover) for a total of 93 days post-treatment completion.
  • Azoospermic males and WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements. However WOCBP must still undergo pregnancy testing as described.
  • The safety and efficacy of apixaban have not been studied in patients with prosthetic heart valves. Therefore, use is not recommended in these patients.

About this study

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.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lab tests for plasma levels of apixaban and anti-10a factorOther

    All patients will have a blood draw at 48 hours prior to elective surgical procedure and then a second blood draw on the morning of the procedure to test apixaban plasma and anti-Xa levels.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Apixaban plasma concentration

    Determine whether the recommended 48 hour pre-procedure discontinuation period is sufficient to achieve minimal apixaban plasma concentration of < 30 ng/ml prior to surgery

    Measured: Prior to elective surgery

Secondary outcomes (2)
  1. Anti-10a apixaban plasma concentration

    Assess changes in anti-Xa apixaban levels following apixaban discontinuation but prior to the procedure

    Measured: Prior to elective surgery

  2. 30 day outcomes assessment

    Incidence of major events within 30 days including bleeding events, arterial thromboembolic events, and deaths caused by bleeding or thrombosis.

    Measured: Up to 30 days post- procedure

Questions about this trial

What is this clinical trial studying?

An observational study of Hemorrhage and Thromboembolism, run by Thomas Jefferson University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Apixaban plasma concentration (time frame: Prior to elective surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02935751, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Sep 2018.
