Cilostazol and Aspirin in Stroke and TIA

August 2, 2024 updated by: Taewon Kim, Incheon St.Mary's Hospital

Cilostazol and Aspirin in Acute Minor Stroke and Transient Ischemic Attack

This study is a randomized, open-labelled trial. We randomly assigned patients within 24 hours after the onset of minor ischemic stroke or high-risk TIA to combination therapy with cilostazol and aspirin or to clopidogrel plus aspirin. The primary outcome was stroke (ischemic or hemorrhagic) during 90 days of follow-up in an intention-to-treat analysis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a randomized, open-labelled trial. We randomly assigned patients within 24 hours after the onset of minor ischemic stroke or high-risk TIA to combination therapy with cilostazol and aspirin (aspirin 100mg with cilostazol 200 mg for 21 days) or to clopidogrel plus aspirin (aspirin 100mg with clopidogrel 75mg for 21 days). The primary outcome was stroke (ischemic or hemorrhagic) during 90 days of follow-up in an intention-to-treat analysis. The primary safety outcome was the moderate-to-severe bleeding event according to (GUSTO) definition. The secondary outcomes were new clinical vascular event (ischemic or hemorrhagic stroke, myocardial infarction, or vascular death), analyzed as a composite outcome and also as individual outcomes. Vascular death was defined as death due to stroke (ischemic or hemorrhagic), systemic hemorrhage, myocardial infarction, congestive heart failure, pulmonary embolism, sudden death, or arrhythmia.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Diagnosis of an acute minor ischemic stroke or TIA
  • Acute minor stroke was defined by a score of 3 or less at the time of randomization on the National Institutes of Health Stroke Scale (NIHSS; scores range from 0 to 42, with higher scores indicating greater deficits)

Exclusion Criteria:

  • Intracerebral Hemorrhage
  • Brain tumor
  • Brain abscess, or other major non-ischemic brain disease;
  • Isolated sensory symptoms (numbness, isolated visual changes, or isolated dizziness or vertigo) without evidence of acute infarction on baseline CT or MRI of the head
  • A score of more than 2 on the modified Rankin scale, immediately before the occurrence of the index ischemic stroke or TIA, indicating moderate disability or worse at baseline
  • An NIHSS score of 4 or more at randomization
  • A clear indication for anticoagulation therapy (presumed cardiac source of embolus, such as atrial fibrillation or prosthetic cardiac valve) or a contraindication to clopidogrel, cilostazol or aspirin
  • History of intracranial hemorrhage
  • Anticipated requirement for long-term non-study antiplatelet drugs or for nonsteroidal anti-inflammatory drugs affecting platelet function
  • Heparin therapy or oral anticoagulation therapy within 10 days before randomization
  • Gastrointestinal bleeding or major surgery within the previous 3 months
  • Planned or probable revascularization (any angioplasty or vascular surgery) within 3 months after screening (if clinically indicated, vascular imaging was to be performed before randomization, whenever possible)
  • Planned surgery or interventional treatment requiring cessation of the study drug
  • TIA or minor stroke caused by angiography or surgery
  • Severe non- cardiovascular coexisting condition, with a life expectancy of less than 3 months

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
New stroke event for 90 days (Ischemic or hemorrhagic)
Time Frame: for 90 days
New stroke event for 90 days (Ischemic or hemorrhagic)
for 90 days
Moderate-to-severe bleeding event according to (GUSTO) definition
Time Frame: for 90 days

Moderate-to-severe bleeding event according to (GUSTO) definition:

Moderate : bleeding requiring transfusion Severe : Fatal or intracerebral bleeding, or bleeding resulting in substantial hemodynamic compromise requiring treatment
for 90 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
New clinical vascular event (ischemic or hemorrhagic stroke, myocardial infarction, or vascular death), analyzed as a composite outcome and also as individual outcomes.
Time Frame: for 90 days
New clinical vascular event (ischemic or hemorrhagic stroke, myocardial infarction, or vascular death), analyzed as a composite outcome and also as individual outcomes. Vascular death was defined as death due to stroke (ischemic or hemorrhagic), systemic hemorrhage, myocardial infarction, congestive heart failure, pulmonary embolism, sudden death, or arrhythmia.
