Efficacy of Oral Metformin in Acute Ischemic Stroke (AIS): a Multicentric Randomized Controlled Trial

Source: ClinicalTrials.gov · Last updated 29 Oct 2026

Brief summary (registry, in English)

The goal of this clinical trial is to study the efficacy of oral Metformin in Acute Ischemic Stroke (AIS). The main hypothesis is to study the efficacy of oral Metformin in patients with acute ischemic stroke presenting within 72 hours of onset in terms of goof modified Rankin scale (mRS) at 90 days. Researchers will compare placebo tablets. Participants will randomised to Metformin or placebo in 1:1 ratio. Additionally, the blood sample will be collected to look for biomarkers hsCRP, Vitamin B12, and Holotranscobalamin at baseline and follow-up.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Any of the following:
    • Patients receiving endovascular therapy or are candidates for any surgical intervention for treatment of stroke.
    • Prior history of stroke of any type (ischemic/hemorrhagic/ subarachnoid hemmorhage)
    • Patients classified as comatose (NIHSS Level of Consciousness (1A) score ≥ 2).
    • Evidence of intracranial hemorrhage in the baseline CT.
    • Pregnancy and lactation.
    • Patients with co-morbid illnesses like chronic liver disease/chronic kidney disease/malignancy limiting their life expectancy.
    • Concurrent participation in any other therapeutic clinical trial/ rehabilitation trial.
    • Patients are already on metformin treatment. • A non-interventional arm of patients who fulfill the eligibility criteria and are already on metformin before the stroke will also be recruited for the purpose of prospective follow-up to assess the outcome at 90 days.
    • Patients without diabetes will not be excluded from the study, as the doses of metformin to be used in our study have been amply used in other studies in non-diabetes conditions for indications like cancer, dementia, polycystic ovarian disease, obesity.

Who the study is looking for

  • Patients with acute ischemic stroke(AIS) within 72 hours of symptom onset, ≥18 years of age, without large vessel occlusion (LVO) will be included in the study.
    • All the following:
  • Adults aged ≥18 years.
  • Patient or Legally Acceptable Representative (LAR) willing to give informed consent before study procedure.
  • Acute stroke is ischemic in origin and radiologically confirmed by Computed Tomography (CT) scan prior to enrolment.
  • Pre-stroke mRS score of 0 or 1 and first ever episode of stroke
  • National Institute Health Stroke Scale (NIHSS) of \>5 (NIHSS Level of Consciousness (1A) score must be \<2).
