What is being measured

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

  1. Yearly Event Rate for Composite Endpoint of Stroke, Transient Ischaemic Attacks, System Thromboembolism, Myocardial Infarction, Other Major Adverse Cardiac Events and Mortality.

    Time to first occurrence of stroke, transient ischaemic attacks, system thromboembolism, myocardial infarction, other major adverse cardiac events and mortality. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  2. Yearly Event Rate for Major Bleeding

    Time to first occurrence of fatal or life-threatening, retroperitoneal, intracranial, intraocular, or intraspinal bleeding, which required surgical treatment, led to a transfusion of a minimum of 2 units of packed cells or whole blood, or led to a fall in hemoglobin of 20g/L or less.

    Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  3. Yearly Event Rate for Major + Minor/Relevant Bleeding

    Time to first occurrence of either major or minor/relevant bleeding. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  4. Yearly Event Rate for Any Bleeding

    Time to first occurrence of any bleeding event. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  5. Yearly Event Rate for Minor Bleeding

    Time to first occurrence of minor bleeding. A minor bleeding event is any bleed that does not qualify as a major bleed. All minor bleeding events not fulfilling one of the criteria for clinically relevant were classified as nuisance bleeds.

    Clinically-relevant was defined as spontaneous skin hematoma ≥25 cm², spontaneous nose bleed >5 min, macroscopic hematuria spontaneous or lasting longer than 24 hours if associated with an intervention, spontaneous rectal bleeding, gingival bleeding >5 min, leading to hospitalization, leading to a transfusion of <2 units of packed cells or whole blood and any other bleeding event considered clinically relevant by the investigator.

    Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

Secondary outcomes (11)
  1. Yearly Event Rate for Stroke

    Time to first occurrence of any fatal or non-fatal stroke. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  2. Yearly Event Rate of Ischaemic Stroke

    Time to first occurrence of any ischaemic stroke. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Time to first occurrence of any transient ischaemic attacks. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  5. Yearly Event Rate for Systemic Thromboembolism

    Time to first occurrence of any non-central nervous system systemic thromboembolism.

    Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  6. Yearly Event Rate of Myocardial Infarction

    Time to first occurrence of any myocardial infarction. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  7. Yearly Event Rate of Other Major Adverse Cardiac Events

    Time to first occurrence of any other major adverse cardiac events. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  8. Yearly Event Rate of Death

    Time to death of any cause. Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  9. Yearly Event Rate for Composite Secondary Endpoint of Ischaemic Stroke, Transient Ischaemic Attacks, Non-central Nervous System Systemic Thromboembolism, Myocardial Infarction, Other Major Adverse Cardiac Events and All-cause Mortality

    Time to first occurrence of ischaemic stroke, transient ischaemic attacks, non-central nervous system systemic thromboembolism, myocardial infarction, other major adverse cardiac events and all-cause mortality.

    Yearly event rate (%) = number of subjects with event / subject-years * 100. Subject years = sum (date of end of treatment - date of start of treatment) of all entered subjects / 365.25

    Measured: 5 years

  10. Severe Adverse Event

    Frequency of patients with severe adverse events.

    Measured: 5 years

  11. Laboratory Analyses

    Frequency of patients with possible clinically significant abnormalities, i.e. with values out of normal range.

    Normal ranges are defined as:

    • Alanine aminotransferase (ALT): 5-45 [U/L]
    • Aspartate aminotransferase (AST): 10-40 [U/L]
    • Bilirubin, total: 0.2-1.0 [mg/dL]

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing dabigatran etexilate in people with Atrial Fibrillation and Stroke, run by Boehringer Ingelheim at 50 sites in 4 countries.

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 8 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: stopped early, as of the sponsor's last update on 19 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 50 sites in Denmark, Netherlands, United States, Sweden. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Feb 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Yearly Event Rate for Composite Endpoint of Stroke, Transient Ischaemic Attacks, System Thromboembolism, Myocardial Infarction, Other Major Adverse Cardiac Events and Mortality. (time frame: 5 years). The study lists 5 primary outcomes in all. 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 19 May 2014.
