About this study
Official title: A Phase III, Multicenter, Multinational, Randomized, Parallel Group, Double-blind Trial of Clopidogrel Versus Placebo in High-risk Patients Aged 45 Years and Older, at Risk of Atherothrombotic Events, and Who Are Receiving Background Therapy Including Low-dose ASA.
RATIONALE:
- Atherothrombosis is a progressive and generalized vascular disease resulting in events leading to myocardial infarction (heart attack), stroke, and vascular death.
- In patients at risk for this disease, it is characterized by an unpredictable, sudden disruption of atherosclerotic plaques, which may lead to total occlusion of artery due to formation of a clot. The use of aspirin (blood thinner agent) for reducing those major ischemic events is either indicated, or recommended by international guidelines. However, aspirin fails to prevent a high percentage of such life-threatening events. Therefore, more effective blood thinning therapy may provide additional clinical benefit to such patients.
- The results of the CURE trial in patients with unstable angina demonstrate the additional benefit of long-term treatment (up to one year) with clopidogrel, (a blood thinner agent), when administered in combination with standard therapy including aspirin. The purpose of CHARISMA is to investigate whether a similar clinical benefit of clopidogrel may apply to a broad population of high-risk patients receiving low-dose aspirin therapy. Such population includes patients with previous cardiovascular, neurovascular or peripheral arterial manifestations of atherothrombosis and patients with combinations of recognized risk factors for atherosclerosis.

OBJECTIVES:
- To assess the efficacy of clopidogrel 75 mg once-daily by comparison with a placebo, in preventing cardiovascular morbidity/mortality. The study will compare the efficacy of the two regimens in preventing the occurrence of major cardiovascular complications (stroke, heart attack, cardiovascular death) in high-risk patients who are otherwise receiving low-dose aspirin therapy (75-162 mg daily).
- To evaluate the safety of clopidogrel in this population, and more specifically the incidence of fatal or severe bleeding (as per GUSTO definition), in order to estimate the global benefit of clopidogrel in this patient population.
Read the detailed description
TREATMENTS:
- Clopidogrel (Plavix® and/or Iscover®) is an agent inhibiting platelet aggregation involved in clot formation. Each tablet contains 75mg of clopidogrel. A matching placebo of clopidogrel is an inactive substance that looks similar to the active clopidogrel tablet.
TREATMENT PLAN:
- There will be two treatment groups; one will receive clopidogrel 75 mg (1 tablet qd), the second matching placebo of clopidogrel (1 tablet qd). These study drugs will be administered on top of low-dose aspirin (75-162 mg qd) systematically prescribed to such patients. In addition, patients enrolled in CHARISMA will be managed as appropriate for their risk factors for atherosclerosis: eg. high blood pressure, high cholesterol, diabetes…etc.
PRIMARY ENDPOINT:
- Combined endpoint of cardiovascular mortality, stroke, acute myocardial infarction.
STUDY EXECUTION:
- Some 7,600 patients per group will be recruited within two years. Patients will be observed over a maximum of 3.5 years.
STUDY TERRITORY:
- Approximately 900 sites throughout North/South America, Europe, Asia, Australia, and South Africa.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing clopidogrel (SR25990) in people with Arteriosclerosis, run by Sanofi at 32 sites in 32 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 18 inclusion and 3 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: finished, as of the sponsor's last update on 23 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 32 sites in United States, Argentina, Australia, Austria, Belgium and 27 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Occurrence of myocardial infarction,stroke or cardiovascular death.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00050817, which also lists 9 linked publications.
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 23 Apr 2012; AzTrials last refreshed its copy on 6 Nov 2026.
