NCT00059306

Brief Summary

The goal of this study is to learn if combination antiplatelet therapy (aspirin and clopidogrel) is more effective than aspirin alone for the prevention of recurrent stroke and cognitive decline, and if intensive blood pressure control is associated with fewer recurrent strokes and cognitive decline. On July 21, 2011 the DSMB recommended terminating the anti platelet arm of the study due to an imbalance of overall and major non-CNS hemorrhagic SAE's and total deaths in the investigational anti platelet combination of aspirin + clopidogrel and an interim statistical analysis that demonstrated futility in the investigational anti platelet arm. It was recommended that patients be continued on standard care of aspirin mono therapy until their study close-out visit. Also, recommended the continuation and completion of the plood pressure arm following the protocol.

Outcome Measures

Primary Outcomes (2)

  • Evidence of clinically defined ischemic stroke (focal neurological deficits persisting for more than 24 hours) confirmed by non-investigational CT or MRI

    Mean follow up of 4 years

  • Evidence of hemorrhagic stroke; a neurologic deficit associated with intraparenchymal or subarachnoid space lesion on CT/MRI or cerebral hemorrhage demonstrated by surgery or autopsy.

    within mean follow-up of 4 years

Secondary Outcomes (1)

  • The difference in the rate of cognitive decline among SPS3 participants assigned to receive aspirin alone versus combination of aspirin and clopidogrel, assessed through repeated neuropsychological tests; and major vascular events.

    within mean follow-up of 4 years

Study Arms (2)

Antiplatelet

ACTIVE COMPARATOR

Participants receive aspirin + placebo OR aspirin + clopidogrel

Drug: aspirinDrug: clopidogrelOther: placebo

Blood pressure

ACTIVE COMPARATOR

The goal of the blood pressure aspect of this trial is to find out if lowering blood pressure after stroke helps to prevent recurrent stroke and preserves cognition.

Other: Target of Blood Pressure

Interventions

Participants receive aspirin + placebo, specifically: aspirin (325 mg) with placebo (an inactive substance). Participants will take 1 of each pill a day until the end of the study.

Antiplatelet

Participants will receive aspirin + clopidogrel, specifically: aspirin (325 mg) with clopidogrel (75 mg)-- Participants will take 1 of each pill a day until the end of the study.

Antiplatelet

Participants will be assigned to one of 2 groups of blood pressure control. The difference between the two groups is the target level of systolic blood pressure-either 130-149 mmHg or below 130 mmHg; to do so, the scientists will use medications that are already in the market for blood pressure management.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

Presence of an S3 (1.5 and 2 cm in diameter corresponding to the qualifying event on DWI; when TIA, ADC image must confirm lesion or T2/FLAIR (hyperintense lesions) (required for all brainstem events) OR multiple S3s on FLAIR/TI(\<1.5 cm in diameter) (hypointense lesions) b. Absence of cortical stroke and large subcortical stroke (recent or remote).

You may not qualify if:

  • To be eligible for entry into the study, the patient must not meet any of the criteria listed below:
  • Disabling stroke (Modified Rankin Scale less than or equal to 4)
  • Previous intracranial hemorrhage (excluding traumatic) or hemorrhagic stroke
  • Age under 30 years
  • High risk of bleeding (e.g. recurrent GI or GU bleeding, active peptic ulcer disease, etc)
  • Anticipated requirement for long-term use of anticoagulants (e.g. recurrent DVT) or other antiplatelets
  • Prior cortical stroke (diagnosed either clinically or by neuroimaging), or prior cortical or retinal TIA
  • Prior ipsilateral carotid endarterectomy
  • Impaired renal function: GFR \<40
  • Intolerance or contraindications to aspirin or clopidogrel (including thrombocytopenia, prolonged INR)
  • A score \< 24 (adjusted for age and education) on the Folstein Mini Mental Status Examination
  • Medical contraindication to MRI
  • Pregnancy or women of child-bearing potential who are not following an effective method of contraception
  • Geographic or social factors making study participation impractical
  • Unable or unwilling to provide informed consent
