Risk of Recurrent Venous Thromboembolism After Provoked Venous Thromboembolism (AURECpro)

October 11, 2019 updated by: Sabine Eichinger, Medical University of Vienna

Risk of Recurrent Venous Thromboembolism in Patients With Provoked Deep Vein Thrombosis of the Leg and/or Pulmonary Embolism: a Prospective Cohort Study

Venous thromboembolism (VTE) is a common disease with an incidence of 1-2/1000 persons per year. VTE is a chronic disease with a considerable risk of recurrence. Patients with unprovoked VTE, i.e. VTE in the absence of a temporary risk factor including surgery, cancer or immobilisation, have a high recurrence risk and indefinite anticoagulation is generally recommended. The recurrence risk of patients with VTE provoked by a transient risk factor is regarded as low. Discontinuation of anticoagulation after three months is recommended because the benefit of reducing the recurrence risk further by prolonged anticoagulation is outweighed by the bleeding risk. However, the newer direct oral anticoagulants are potentially associated with a lower bleeding risk than vitamin K antagonists. Because they are also meanwhile widely available and are convenient there is a trend towards prolonging anticoagulation also in patients with a VTE after a transient provoking factor. However, the definition of transient provoking factors is imprecise and a distinct categorization according to the risk of recurrence is lacking. Preliminary evidence suggests that the recurrence risk varies considerably between the different transient provoking factors. In a prospective cohort study, the investigators will include patients with a deep vein thrombosis or pulmonary embolism provoked by a transient risk factor defined according to Guidance of the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis (Kearon et al., J Thromb Haemost 2016; 14: 1480-3) after discontinuation of anticoagulation. The study endpoint is recurrent symptomatic VTE.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 15, 2019

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
