Brief Summary
Official Title: “PRoFESS - Prevention Regimen For Effectively Avoiding Second Strokes: A Double-Blind, Active and Placebo Controlled Study of Aggrenox vs. Clopidogrel, With and Without Micardis”
Condition Keyword(s):
The purpose of the trial is to determine if extended-release dipyridamole + aspirin [Aggrenox, Asasantin] is superior to clopidogrel [Plavix], and if telmisartan [Micardis, Gliosartan, Kinzal, Kinzalmono, Predxal, Pritor, Samertan, Telmisartan] is superior to placebo, in the presence of background antihypertensive therapy, in prevention of a second stroke in patients who have recently suffered a stroke and therefore are at high risk of suffering another one.

Criteria for Participation in this Clinical Trial
Inclusion Criteria:
- Male or female subjects 55 year or older who have suffered an ischemic stroke within the past 90 days and who meet all other inclusion criteria.
- Include also patients of ages 50 - 54 years and/or 90 to 120 days after the qualifying stroke provided the patient has at least two of the following additional risk factors:
- Diabetes mellitus
- Hypertension (systolic BP 140 or diastolic BP 90)
- Smoker at time of qualifying stroke
- Obesity (BMI>30; BMI=weight (kg)/[height (m)]2)
- Previous vascular disease (stroke, MI, or peripheral arterial disease prior to qualifying stroke)
- End-organ-damage (retinopathy, LVH, or microalbuminuria)
- Hyperlipidemia
Exclusion Criteria:
- hemorrhagic stroke (must be ruled out by imaging);unable to give informed consent;
- known brain tumor, severe renal or hepatic insufficiency, current active peptic ulcer disease, severe coronary artery disease including unstable angina pectoris or an MI within the previous 3 months,or history of a hemostatic disorder or systemic bleeding;
- hyperkalemia;uncorrected volume or sodium depletion;
- pre-stroke history of dementia;modified Rankin score greater than 4;
- qualifying stroke induced by surgical or cardiovascular procedure;
- uncontrolled hypertension at entry above 180/110 mmHg (goal BPs are lower);
- SBP 120 mmHg or less for hospitalized patients; currently taking an ARB and not able or willing to switch to alternative; required or planned continuing treatment with antithrombotics or anticoagulants including heparin or warfarin or non-study platelet inhibitors;
- syndrome of asthma, rhinitis and nasal polyps;
- scheduled for major surgery, carotid endarterectomy, or carotid angioplasty (4 weeks post surgery is allowed);
- unlikely to be released from hospital following the qualifying stroke or presence of a severe disability likely to lead to being bedridden or demented or a non-vascular disease or condition which makes it unlikely that the patient will survive to the end of the trial;
- history of thrombocytopenia or neutropenia.
