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 100 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Men and women over 18 years of age with NVAF requiring anticoagulant treatment with a DOAC. The prescription of the treatment will be previous and independent to the inclusion of the patient in the study. Patients who will initiate treatment (which will only be evaluated prospectively) and patients already in treatment (which will also be evaluated retrospectively) will be included.

Who may be able to join

  • Men or women over 18 years of age
  • Patients with non-valvular atrial fibrillation (NVAF).
  • Patients who are going to receive or are receiving treatment with any of the DOACs (dabigatran, rivaroxaban, apixaban or edoxaban) for the prevention of stroke and systemic embolism in adult patients with NVAF, according to the drug label.
  • Patients who agree to participate in the study and give their written consent.

Who cannot join

  • Patients on treatment with other anticoagulants.
  • Patients suffering from a malignant or terminal disease whose life expectancy is less than 6 months.

About this study

Official title: Identification of Clinical and Pharmacogenetic Factors Predictive of Response to New Oral Anticoagulants in the Treatment of Non-valvular Atrial Fibrillation.

Post-authorization observational, prospective, follow-up study of a cohort of patients with non-valvular atrial fibrillation who are treated with direct oral anticoagulants (DOACs) to evaluate the clinical course (occurrence of stroke, major bleeding and mortality) and its correlation with clinical, pharmacokinetic (plasma concentrations), pharmacodynamic (haemostatic) and pharmacogenetic factors.

Read the detailed description

Post-authorization observational, prospective, follow-up study of a cohort of patients with non-valvular atrial fibrillation treated with direct oral anticoagulants (dabigatran, rivaroxaban, apixaban and edoxaban) to assess the clinical course (occurrence of stroke, other ischemic or bleeding events and mortality) and its correlation with clinical, pharmacokinetic (plasma concentrations), pharmacodynamic (haemostatic) and pharmacogenetic factors.

Patient selection and follow-up will be performed in 6 public Spanish hospitals: Hospital Universitario de la Princesa, Hospital Universitario La Paz, Hospital Universitario Ramón y Cajal, Fundación Jiménez Díaz, Hospital Gómez Ulla (Madrid) and Hospital Universitario de Burgos (Burgos). To reduce variability, the determination of anticoagulant activity will be performed in the Hematology Service of the Hospital Universitario de Burgos and the measurement of plasma concentrations and genotyping of all patients in the Clinical Pharmacology Service of the Hospital Universitario de la Princesa.

Patients who are to receive or are receiving one of the four DOACs currently available in Spain will be informed about the characteristics of this study and will be asked to sign the consent form for their participation. The treatment or clinical management of these patients at each centre will not be modified. They will be asked three blood samples, coinciding with other tests that will be carried out to monitor their pathology (one blood sample for the study of the effect on coagulation, another for drug quantification in plasma and another for genetic studies) with the only requirement that they must have been treated with the drug for at least one week so that they have spent more than 5 half-lives and are in steady state. The samples will be extracted in the morning, before medication intake (trough concentrations).

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Fundación de Investigación Biomédica - Hospital Universitario de La Princesa at 6 sites in Spain.

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: status not confirmed, as of the sponsor's last update on 6 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Spain. 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?

Results are not available in the source record.

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?

Major haemorrhages (time frame: Throughout the follow-up, i.e. for at least 15 months and up to 30.). 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 6 Jun 2023.
