Trial Information

Aspirin in Reducing Events in the Elderly

Low dose aspirin therapy has been shown to reduce the risk of vascular events, largely in
middle-aged people. There is also some evidence of its potential to reduce the rate of
intellectual decline and certain types cancers in older participants. However, part of the
benefit of aspirin may be offset by adverse effects, such as those related to its potential
to cause bleeding.

The balance of risks and benefits of low dose aspirin has not been established in older
persons. Previous studies on the effects of aspirin in primary prevention have mainly
focused on cardiovascular outcomes. In the elderly, these alone may not be the most
appropriate measure of benefit associated with aspirin treatment. Prolonging a life free of
functional disability in a healthy aging population would be the most desirable benefit of
aspirin as a preventative medicine.

ASPREE will determine whether taking a daily low-dose aspirin will extend the length of a
disability-free life in healthy participants aged 65 years and above.

Inclusion Criteria:

- Men and women

- African American and Hispanic persons age 65 or older

- Any person from another ethnic minority group age 70 or older

- Willing and able to provide informed consent, and willing to accept the study

[ASPREE has completed enrollment of Caucasian participants in the US.]

Exclusion Criteria:

- A history of a diagnosed cardiovascular event

- A serious intercurrent illness likely to cause death within the next 5 years, such as
terminal cancer or obstructive airways disease

- A current or recurrent condition with a high risk of major bleeding, ex: cerebral

- Anemia

- Absolute contraindication or allergy to aspirin

- Current participation in a clinical trial

- Current continuous use of aspirin or other anti-platelet drug or anticoagulant for
secondary prevention. People with previous use of aspirin for primary prevention may
enter the trial, provided they agree to cease existing use of aspirin and understand
that they may be subsequently randomly allocated to low dose aspirin or placebo.

- A systolic blood pressure ≥180 mmHg and / or a diastolic blood pressure ≥105 mmHg

- A history of dementia

- Severe difficulty or an inability to perform any one of the 6 Katz ADLs

- Non-compliance to taking pill
