Effect of Acetaminophen on Neurological Outcome in Acute Ischemic Stroke Patients Undergoing Endovascular Treatment (ACEAIS)

May 3, 2025 updated by: Ruquan Han, Beijing Tiantan Hospital
Neuro-inflammation response plays an important role in the development of acute ischemic stroke(AIS). The aim of this study was to conduct a prospective randomized controlled study on the effect of acetaminophen on long-term neurological prognosis in AIS patients undergoing endovascular treatment(EVT). The primary outcome was the incidence of neurological independence (mRS 0-2, modified Rankin scale) at 90 days after surgery. The secondary outcome measures were early neurological outcome (NIHSS score at 7 days after surgery or at discharge) and the incidence of symptomatic intracerebral hemorrhage during hospitalization. This study explored the effect of acetaminophen on the prognosis of neurological function of patients, and the expected results provide evidence of safety and effectiveness for acetaminophen to improve the prognosis of neurological function of patients, and provide theoretical and practical basis for the subsequent "new use of old drugs" of acetaminophen and large sample and multi-center clinical research or clinical application.

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.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
892

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.

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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:

  • Age ≥18 years old; computer tomography angiogram (CTA), Magnetic Resonance Angiography (MRA), MRA) or digital subtraction angiography (DSA) confirmed the presence of large intracranial artery occlusion (intracranial internal carotid artery, anterior cerebral artery, M1 and M2 segments of middle cerebral artery, basilar artery, posterior cerebral artery); Endovascular treatment including intra-arterial thrombolysis, mechanical thrombectomy, angioplasty, etc. was performed (within 24 hours of onset). The NIHSS score at admission was 6-26. The mRS Score before onset was less than 2. Patients or their legal representatives provided written informed consent

Exclusion Criteria:

The mRS Score before the stroke was ≥2. Intracranial hemorrhagic diseases: cerebral hemorrhage, subarachnoid hemorrhage, etc. Patients had a history of coagulopathy, systemic bleeding, thrombocytopenia or neutropenia. Renal insufficiency with elevated serum creatinine (> 2 times the upper limit of normal); Severe hepatic insufficiency or liver disease, with elevations in liver enzymes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, or gamma-glutamyl transpeptidase) of more than twice the upper limit of the normal range; Patients with severe active liver disease; Patients with severe heart and lung diseases considered by the investigator to be ineligible for the study; DSA examination is contraindicated, severe contrast agent allergy or iodine contrast agent is absolutely contraindicated; Women of childbearing age, pregnant or lactating women who have a negative pregnancy test but refuse to use effective contraception; Inability to complete the study due to mental disorders, cognitive or emotional disorders; Allergy to acetaminophen; Other patients who were not included in the study in the opinion of the investigator (reasons indicated)
