About this study

Official title: Benefit/Risk in Real Life of New Oral Anticoagulants and Vitamin K Antagonists in the Treatment of Non Valvular Atrial Fibrillation in Patients Aged 80 Years and Over, Living at Home or in Nursing Home. A Prospective Cohort Study

The aim of the study is to compare, in real life, the risk benefit (including both major bleeding and thrombotic events (TE) and death from any cause) associated with direct oral anticoagulants (DOA) and with anti vitamin K (VKA) in older adults (≥ 80 years) suffering from non valvular atrial fibrillation and living in community or nursing home settings.

An observational multicenter prospective inception cohort will be conducted within the PRESAGE-Network, an ongoing active network on drug safety in older adults in France involving a sample of general practitioners (GPs) and pharmacists, for an active surveillance of drug safety in older adults. GPs and pharmacists will prospectively include all octo+ patients they care for, newly treated with an oral anticoagulant (VKA or DOA) for nv AF and will follow them during 2 years at least.

Read the detailed description
  • Context: Oral anticoagulation is recommended for prevention of stroke and thrombo-embolic events in people aged 80 years and over (octo+) suffering from non vavular atrial fibrillation (nv AF) and without contraindication to anticoagulant therapy. Two drug classes are available to achieve this oral anticoagulation: the vitaminK antagonists (VKA, warfarin, fluindione and acenocoumarol) or the direct oral anticoagulants (DOA, dabigatran, rivaroxaban and apixaban). The data of evidence-based and post-marketing literature on the benefit/risk ratio of DOA comparatively to VKA are limited, conflicting, potentially biased and finally inconclusive in this population. Nevertheless, octo+ are the age bracket the most at risk for nv AF and the population with the highest risk of both anticoagulant-related major bleedings and AF-related thrombotic (TE) events.
  • Objectives: The aim of the study is to assess and compare the real benefits and harms of the two therapeutic strategies available in routine practice, for the anticoagulation in octo+ suffering from nvAF. The main objective is to estimate and compare a composite event including major bleeding, TE events and death from any cause of DOA and VKA in octo+ suffering from nv AF and living in community or nursing home settings. The secondary objectives are, in this population: to estimate and compare the composite event of each DOA (dabigatran, rivaroxaban, and apixaban) with the composite event of VKA, to estimate and compare the rate of occurrence of each component of the composite event in patients exposed to DOA as compared to patients exposed to VKA, to identify factors associated with the occurrence of major bleeding events and TE events in patients exposed to oral anticoagulants (OAC), to describe others adverse drug reactions (ADRs) (not serious bleeding and TE events; other serious or not serious ADRs) and to provide related rates in users of VKA and DOA as well as individual DOA, to describe the utilization patterns of oral anticoagulants.
  • Design: An observational multicenter prospective inception cohort will be conducted within the PRESAGE-Network, an ongoing active network on drug safety in older adults in France involving a sample of general practitioners (GPs) and pharmacists, for an active surveillance of drug safety in older adults.

What is being measured

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

  1. Composite of major bleeding events or thromboembolic events or death from any cause

    Major bleeding is defined as a bleeding resulting in death, requiring hospital admission, resulting in persistent or significant disability/incapacity, or being life threatening, according to the WHO definition of seriousness of Adverse Drug Reactions (ADRs). Thromboembolic events (TE) include: Ischemic stroke, systemic or pulmonary embolism.

    Measured: 2 years at least

Secondary outcomes (5)
  1. Major bleeding eventThromboembolic event

    Bleeding resulting in death, requiring hospital admission, resulting in persistent or significant disability/incapacity, or being life threatening, according to the WHO definition of seriousness of Adverse Drug Reactions (ADRs)

    Measured: 2 years at least

  2. Thromboembolic event

    Ischemic stroke, systemic or pulmonary embolism

    Measured: 2 years at least

  3. All adverse events

    All adverse events

    Measured: 2 years at least

  4. Risk factors of TE events or major bleeding events

    Risk factors of TE events or major bleeding events

    Measured: 2 years at least

  5. Patterns of use of oral anticoagulants

    Pattern of use will be described by: characteristics of the treated population (age, comorbidities), drug indication, dose and regimen, time on treatment, reason of discontinuation where applicable, concomitant drugs

    Measured: 2 years at least

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 4 inclusion and 2 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 29 Mar 2022. 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 France. 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?

Composite of major bleeding events or thromboembolic events or death from any cause (time frame: 2 years at least). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Mar 2022.
