Brief Summary

Acute ischemic stroke caused by blockage of a large artery in the brain is one of the leading causes of death and long-term disability worldwide. For patients with this type of stroke, endovascular thrombectomy (EVT), a procedure that removes the blood clot and restores blood flow to the brain, has become the standard treatment. However, even when blood flow is successfully restored, many patients continue to experience disability because of ongoing brain injury caused by inflammation, oxidative stress, and damage to brain cells after the stroke. This study aims to evaluate whether tirzepatide, a medication that activates both glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) pathways, can improve recovery in patients with acute ischemic stroke caused by large vessel occlusion who receive thrombectomy. Tirzepatide is currently approved for the treatment of conditions such as type 2 diabetes and obesity. Previous studies have shown that tirzepatide can improve blood sugar control, reduce body weight, and provide beneficial effects on cardiovascular health. Laboratory studies and early clinical evidence suggest that medications targeting GLP-1 and GIP pathways may also have protective effects on the brain by reducing inflammation, protecting brain cells, improving blood vessel function, and supporting recovery after stroke. In this study, eligible patients with acute ischemic stroke caused by blockage of a major brain artery will be randomly assigned to receive either tirzepatide plus standard stroke care or standard stroke care alone. Participants will receive two subcutaneous injections of tirzepatide: the first dose before the thrombectomy procedure and the second dose 7 days after the procedure. The study will include multiple hospitals and will use independent assessment of outcomes to ensure reliable evaluation of treatment effects. The primary purpose of this study is to determine whether early treatment with tirzepatide can improve functional recovery 90 days after stroke, measured by the patient's ability to perform daily activities and live independently. The study will also evaluate whether tirzepatide is safe in patients with acute ischemic stroke by monitoring adverse events, complications, and other clinical outcomes. The findings from this study may provide important evidence for a new treatment approach to improve recovery after thrombectomy and reduce disability among patients with severe ischemic stroke.

Outcome Measures

Primary Outcomes (2)

  • The primary efficacy outcome: Proportion of patients achieving an excellent functional outcome

    A excellent functional outcome is defined as modified Rankin Scale (mRS) score of 0-1 at 90 days. The Modified Rankin Scale ranges from 0 to 6, where 0 indicates no symptoms, 1 indicates symptoms without significant disability, 2 indicates slight disability, 3 indicates moderate disability, 4 indicates moderately severe disability, 5 indicates severe disability, and 6 indicates death. Higher scores indicate worse functional outcomes.

    90 ± 7 days after randomization

  • The primary safety outcome: All-cause mortality

    death from any cause within 90 days

    90 ± 7 days

Secondary Outcomes (3)

  • The secondary efficacy outcome: Distribution of mRS scores at 90 days after randomization

    90 ± 7 days

  • The secondary efficacy outcome: Proportion of patients achieving an good functional outcome

    90 ± 7 days

  • The secondary safety outcome: Symptomatic intracranial hemorrhage (sICH)

    within 48 hours after thrombectomy

Other Outcomes (8)

  • Early neurological improvement

  • Recanalization rate of the target LVO vessel

    at 7 days after EVT or hospital discharge

  • Health-related quality of life

Masking Details
This study will employ a blinded-endpoint assessment design. Outcome measures, including 90-day mRS assessment, EQ-5D-5L questionnaire, neurological deficit evaluations during hospitalization, and imaging assessments, will be performed by trained investigators who are unaware of treatment allocation. Assessments will be conducted through either face-to-face visits or telephone follow-up.

Model Details: This study is designed as a multicenter, randomized, controlled trial with blinded endpoint assessment. A total of 430 patients with acute ischemic stroke due to anterior-circulation large vessel occlusion (LVO) who are eligible for endovascular thrombectomy (EVT) will be recruited from 30 participating centers across China. Patients will be stratified by study center and centrally randomized in a 1:1 ratio to receive either early tirzepatide intervention or standard care (control). Participants in the intervention group will receive two subcutaneous injections of tirzepatide: the first administered before EVT and the second on day 7 after the procedure. All participants will be followed for 90 days, and the efficacy and safety of early tirzepatide intervention will be evaluated, with functional outcome at 90 days as the primary efficacy endpoint.
