Brief Summary:
The use of acetylsalicylic acid in the primary prevention of cardiovascular events has been extensively studied but to a lesser extent in patients with moderate levels of cardiovascular risk. The current study is designed to prove the efficacy and tolerability of 100 mg enteric-coated Aspirin versus placebo in the prevention of cardiovascular disease (CVD) events, which include fatal and nonfatal myocardial infarction, fatal and nonfatal stroke and CV death, in a population with no history of known CVD who are at moderate risk of major CHD events (approximately 10-20% 10 year CHD risk). This corresponds to a patient population mean 10-year CVD risk of approximately 30%. Subjects are treated in a standard care setting and may receive treatment for the underlying risk factors as defined by the treating physician. Outcome events will be adjudicated by an Endpoint Adjudication Committee and the study will be monitored by an independent Data Safety Monitoring Board.

Condition or disease Intervention/treatment Phase
Moderate Risk of CVD Drug: Aspirin (Acetylsalicylic acid, BAYE4465) Drug: Placebo Phase 3

Detailed Description:

Summary of substantial Protocol amendments

Amendment #2 from 09-APR-2008:

  • Systolic blood pressure (SBP) limit of 170 mmHg has been added to the exclusion criteria
  • Exclusion of patients currently taking anticoagulant medication
  • A longer interval between the daily dose of study drug and ibuprofen
  • Revised wording in moderate risk definitions for coronary heart disease (CHD) and cerebrovascular disease (CVD): "To evaluate the clinical effects of a 100 mg/day enteric-coated acetylsalicylic acid versus placebo in the reduction of CVD events in patients at moderate risk of major CHD events (approximately 10 to 20% 10-year CHD risk; approximately 20 to 30% 10-year risk of CVD). This corresponds to a patient population mean 10-year CVD risk of approximately 30%."

Amendment #3 from 02-JAN-2009

• Increase in the number of allowed risk factors for males, age is no longer a risk factor

Amendment #4 from 02-OCT-2013

  • The primary endpoint is changed to include confirmed UA and TIA.
  • The estimated event rate is changed to 1.5% per year due to new information.
  • Effect size (risk reduction) changed from 14.9% to 17 to 18%.
  • Achieving 60,000 person-years instead of 1488 primary endpoint events
  • Additional treatment and follow-up for a maximum of another 12 months.
  • Change to reduced adverse event and concomitant therapy reporting

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time to the First Occurrence of the Composite Outcome of MI (Myocardial Infarction), Stroke, Cardiovascular Death, UA (Unstable Angina) or TIA (Transient Ischemic Attack) [ Time Frame: Until follow-up (approximate 6 years) ]
    The primary efficacy endpoint was a composite outcome consisting of the first occurrence of confirmed MI, stroke, cardiovascular death, UA, TIA. The time to event was defined as the number of days from the date of randomization to the date of the event confirmed by adjudication. The numbers of days for milestones when 1%, 2%, 3% and 4% of the subjects have reached endpoint events were estimated from Kaplan-Meier-Analyses.


Secondary Outcome Measures :
  1. Time to the First Occurrence of the Composite Outcome of Cardiovascular Death, MI, or Stroke (Ischemic, Hemorrhagic, or Unknown) [ Time Frame: Until follow-up (approximate 6 years) ]
    The time to Composite outcome consisting of the first occurrence of cardiovascular death, MI, or stroke (ischemic, hemorrhagic, or unknown) was defined as the number of days from the date of randomization to the date of the event confirmed by adjudication. The numbers of days for milestones when 1%, 2%, 3% and 4% of the subjects have reached endpoint events were estimated from Kaplan-Meier-Analyses.

  2. Time to the First Occurrence of the Individual Components of the Primary: Non-fatal MI, Total MI, Non-fatal Stroke, Total Stroke, Cardiovascular Death, UA and TIA [ Time Frame: Until follow-up (approximately 6 years) ]
    The time to event was defined as the number of days from the date of randomization to the date of the event confirmed by adjudication. The numbers of days for milestones when 1%, 2%, 3% and 4% of the subjects have reached endpoint events were estimated from Kaplan-Meier-Analyses.

  3. Time to All-cause Mortality, the First Occurrence of All Cancers Excluding Non-melanoma Skin Cancer (NMSC) and the First Occurrence of Colon Cancer [ Time Frame: Until follow-up (approximately 6 years) ]
    The time to event was defined as the number of days from the date of randomization to the date of the event confirmed by adjudication. The numbers of days for milestones when 1%, 2%, 3% and 4% of the subjects have reached endpoint events were estimated from Kaplan-Meier-Analyses.

  4. Incidence of All-cause Mortality, All Cancers Excluding Non-melanoma Skin Cancer and Colon Cancer [ Time Frame: Until follow-up (approximately 6 years) ]
  5. Incidence of Confirmed MI, Stroke, Cardiovascular Death, UA, and TIA Separately [ Time Frame: Until follow-up (approximately 6 years) ]
    The percentages of subjects with the efficacy endpoints of confirmed MI, stroke, cardiovascular death, UA and TIA are reported separately. *all other CV death without fatal MI and fatal stroke


Other Outcome Measures:
  1. Number of Subjects With Adjudicated GI Bleeding by Severity [ Time Frame: Until follow-up (approximate 6 years) ]
  2. Incidence of Composite Outcomes and Non-fatal MI [ Time Frame: Until follow-up (approximate 6 years) ]
  3. Incidence of Composite Outcomes and Individual Outcomes in Per-protocol Population [ Time Frame: Until follow-up (approximate 6 years) ]
    *all other CV death without fatal MI and fatal stroke.
