Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • the investigators included both males and females, aged between 18 and 80 years, who experienced their first-ever posterior-circulation ischaemic stroke and presented with gait ataxia and score at least 1 point on the items gait, stance, trunk or heel-shin-slide of the Scale for the Assessment and Rating of Ataxia (SARA) and 47 points or less on the Berg Balance Scale (BBS).
  • All of our patients underwent randomisation during the first 24 hours of the symptoms' onset, and within the first 24 hours from the time at which the patient's condition was last reported to be normal for wake-up stroke patients.

Who cannot join

  • the investigators excluded patients with modified Rankin Scale (mRS) score of 5 or more, physical or mental conditions that would not allow safe participation in the study or would influence the assessment of outcomes (e.g., dementia, disturbed conscious level, severe aphasia, etc.).

  • the investigators excluded participants who underwent intravenous thrombolysis, carotid, cerebrovascular, or coronary revascularization during the first week of the trial to avoid clouding of efficacy and safety analysis.

  • the investigators excluded participants who experienced organ failure such as renal failure and liver cell failure, active malignancies, and patients with a known bleeding diathesis or coagulation disorder, a history of intracerebral hemorrhage, gastrointestinal bleeding within the past 6 months, or major surgery within 30 days before randomisation .

About this study

Official title: The Safety and Efficacy of Acetyl-leucine in Post-stroke Ataxia: a Randomized Placebo-controlled Trial

Along with the current clinical trial, the efficacy and safety of 4 gram of acetyl-leucine daily for three months in patients with post-stroke ataxia following posterior-circulation ischaemic stroke assessed through BBS, SARA, and mRS, and possible adverse effects.

Read the detailed description

the investigators will conduct our double-blinded, placebo-controlled, parallel-group trial in Kafr-Elsheikh University in the time between 1st January 2026 to 1st July 2026.

the study will include 200 post-circulation AIS patients who will undergo randomization and divided into two groups; The (A) group, which consisted of 100 patients who administered (a 4 gram of acetyl-leucine per day) and the (B) group, which had 100 patients who administered a placebo during the first 24 hours of stroke onset and for 3 months.

Both groups received (open-label 300 mg loading dose aspirin and 300 mg loading clopidogrel during the first 24 hours of stroke onset, followed by 75 mg clopidogrel and 100 mg aspirin once daily from the 2nd to the 90th day.

The diagnosis of ischemic stroke was established through a detailed clinical history and examination and suitable brain imaging. All of the patients had CT of the brain and CT angiography (CTA) including the aortic arch through the circle of Willis before thrombolysis; the CT of the brain was performed on the 64-slice dual-source spiral CT scanner of Somatom definition by Siemens, and the supratentorial compartment scans were imaged with 5-8mm contiguous sections and the brain stem and cerebellum scans were imaged with 3-5mm slices, and we obtained eighteen images for each series. After thrombolysis, all of the patients underwent an MRI brain on a 1.5 T (Siemens Essenza) MR system, stroke protocol: T1W, T2W, fluid attenuation inversion recovery imaging (FLAIR), diffusion-weighted imaging (DWI), T2 Echo Gradient, and MRA brain \& neck time of flight (TOF) if CTA was contraindicated; the investigators performed an additional brain CT scan after 24-36 hours to evaluate hemorrhagic transformation. (8), and considered hemorrhagic transformation symptomatic if the NIHSS score increased by 4 points or more. (9) The computed tomography (CT)/ magnetic resonance imaging (MRI) examinations were assessed in our study by two highly experienced professionals: a senior stroke physician and a senior radiologist.

the investigators identified posterior-circulation stroke (PCS) when ischemic occlusion affected basilar, posterior cerebral or vertebral arteries

What is being measured

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

  1. value of the Berg balance scale (BBS)

    the primary efficacy endpoint is balance as assessed using the BBS (14). The BBS is considered the gold standard for evaluating balance in people after stroke (20).

    a 14-item test that assesses an individual's balance and risk of falling. It measures static and dynamic balance through a series of tasks, with each item scored on a scale of 0 to 4, for a total possible score of 56, with higher score related to more impairment in balance

    Measured: 90 days

  2. the rate of participants who suffered from treatment-related side effects

    the primary safety endpoint the rate of participants who suffered from treatment-related side effects assessed via questionnaire.

    Measured: 90 days

Secondary outcomes (2)
  1. value of Scale for the Assessment and Rating of Ataxia (SARA)

    the first secondary efficacy endpoint is the severity of ataxic symptoms, as determined by the Scale for the Assessment and Rating of Ataxia (SARA)

    The SARA is a tool for assessing ataxia. It has eight categories with accumulative score ranging from 0 (no ataxia) to 40 (most severe ataxia).

    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 favourable stroke outcome is considered with mRS value equal to two or less.

    Measured: 90 days

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 2 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: looking for participants now, as of the sponsor's last update on 10 Dec 2025. 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Mohamed G. Zeinhom, MD (2001009606828, mohamed_gomaa@med.kfs.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

value of the Berg balance scale (BBS) (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 NCT07275749, which also lists 2 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 10 Dec 2025.
