About this study

Official title: Clopidogrel Versus Cilostazol in Ischemic Stroke, a Randomized Controlled Trial

Along with the current clinical trial, the efficacy and safety of a 300 mg loading dose of clopidogrel administered within 24 hours of the first-ever moderate to severe ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.

Read the detailed description

The investigators conducted a single-blinded randomized controlled trial after approval of the ethics committee of the faculty of medicine at Kafr el-Sheik University.

The investigators got written informed consent from all eligible patients or their first order of kin before randomization.

The study will be composed of 2 arms clopidogrel arm, which consisted of 435 patients who received a 300 mg loading dose followed by 75 mg once daily from the 2nd to the 90th day), and the cilostazol arm, consisting of 435 patients who received (a 200 mg loading dose during the first 24 hours of stroke onset followed by 100 mg twice daily from the 2nd day to the 90th day),

Study Procedures:

Every patient in our study will undergo:

clinical workup: History, clinical assessment \& NIHSS were recorded on admission, day 7, and the Modified Rankin Scale as a follow-up after one week and 3 months.

Detection of Risk Factors \& Profiles:

Echocardiography TTE: in indicated patients ECG Monitoring: daily ECG monitoring will be performed in indicated patients. 3- Carotid Duplex: carotid duplex in indicated patients.

4- ESR \& Lipid Profile\& liver functions: All will be tested routinely for all patients.

Imaging Follow-UP Non-contrast CT brain on admission Day 2 MRI: after 2 days of admission, all the patients in this study will have a brain MRI (stroke protocol; T1W, T2W, FLAIR, DWI, T2 Echo Gradient, MRA of all intra-cerebral vessels).

CT brain: Any patient with unexplained clinical deterioration at any time throughout his/her hospital stay will be urgently imaged by CT.

Primary End Point:

The primary efficacy outcome was the rate of new stroke at 90 days, and the primary safety outcome was the rate of drug hemorrhagic complications using the PLATO bleeding definition.

  • Secondary End Point: The secondary efficacy outcomes were to evaluate the rates of patients who achieved a significant reduction in NIHSS (decrease of four points or more) at the seventh day or discharge compared to baseline, the rates of a favorable outcome with (mRS = 0-2) after 90 days in a face-to-face interview in the outpatient clinic, rate of recurrent ischemic stroke, rate of a composite of recurrent stroke, myocardial infarction and death due to vascular events after 90 days of follow-up, while the secondary safety outcome was the rate of treatment-related adverse effects assessed by a follow-up questionnaire

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. rate of new stroke

    Rates of new stroke occur within three months of treatment. The investigators will perform follow-ups of the patient during visits to the outpatient clinic, and brain CT and/ or MRI will be done if there is suspicion of new stroke.

    Measured: 90 days

  2. Rate of drug-related hemorrhagic complications

    the rate of drug hemorrhagic complications which was evaluated using the PLATO bleeding definition which classified hemorrhagic complications into three types as follows: Major bleeding which had one or more of the following criteria: fatal bleeding, intracranial, intrapericardial, bleeding associated with reduction of hemoglobin > 3-5 g/dl, bleeding required transfusion of two to four units whole blood or PRBCs, bleeding produced hypovolemic shock or severe hypotension that required pressor or surgery; Minor bleeding that required medical intervention to stop or treat bleeding: Minimal bleeding: any bleeding that did not require intervention or treatment such as bruising, bleeding gums, oozing from injection sites.

    Measured: 90 days

Secondary outcomes (4)
  1. Rate of new ischemic stroke at 90 days

    The investigators will perform follow-ups of the patient during visits to the outpatient clinic, and brain CT and/ or MRI will be done if there is suspicion of new ischemic stroke.

    It ranges from 0 to 42; the lower the score, the better the stroke condition. The improvement will be counted only if there is a decrease in NIHSS score by four points or more within one week of stroke onset.

    Measured: 90 days

  2. value of Modified Rankin Scale(mRS) at three months

    mRS Measures the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability; its value ranges from 0 to 6; the lower the score, the better the stroke outcome. A favorable stroke outcome is considered with mRS value equal to two or less.

    Measured: 3 months

  3. rate of composite recurrent stroke, myocardial infarction, and death due to vascular events

    Rates of new stroke, TIA, myocardial infarction, or death from vascular events within three months of treatment, the investigators will perform follow-ups of the patient during visits to the outpatient clinic and perform needed investigations such as brain imaging, Electrocardiography, arterial and venous duplex ultrasound imaging

    Measured: 3 months

  4. rate of drug adverse effects

    Drug adverse effects: all side effects related to the drugs of our study will be reported

    Measured: 90 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Clopidogrel tablet and Cilostazol 100 MG in people with Ischemic Stroke, run by Kafrelsheikh University at 1 site in Egypt.

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 1 inclusion and 6 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 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. 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?

rate of new stroke (time frame: 90 days). The study lists 2 primary outcomes in all. 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 NCT06242132, which also lists 4 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 19 Sep 2024.
