New stroke drug shows promise in early safety trial
NCT ID NCT00821821
First seen Jun 26, 2026 · Last updated Jul 17, 2026 · Updated 3 times
Summary
This study tested a drug called Edaravone (MCI-186) in 36 people who had an acute ischemic stroke. The goal was to check the drug's safety and how the body processes it. Participants received either Edaravone or a placebo through an IV over 72 hours. The trial was completed, but it was too small to determine if the drug improves stroke recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Edaravone (MCI-186)
- What this could lead to
- If successful, this could point toward a treatment to limit brain damage after a stroke.
- What could go wrong
- This is a small, early-phase trial focused on safety and drug levels, not on proving the drug works. The results may not lead to a proven treatment.

Inclusion Criteria: * Full functional independence prior to the present stroke (as evidenced by a pre-morbid modified Rankin Scale score of 0-2 * Clinical diagnosis of acute stroke with CT scan ruling out intracranial hemorrhage * Onset of symptoms within 1-24 hours of commencement of infusion of study drug * Measurable deficit on NIHSS (as evidenced by a score of 3-15) * Full consciousness (i.e. the score for NIHSS item 1a=0) * Written valid informed consent is obtained from the subject or his/her next of kin or legal representative if the subject is fully conscious (i.e. the score for NIHSS item 1a = 0) but unable to read and/or sign the ICF, in accordance with National legislation and local IRB requirements Exclusion Criteria: * Subjects who are unlikely to complete the infusion of investigational product and/or are unlikely to undergo active medical management during that period due to a severe clinical condition * Subjects with severe illness with life expectancy less than 6 months * Body weight in excess of 120 kg * Subjects who have received rTPA or other thrombolytics (e.g. urokinase, streptokinase, reteplase, tenecteplase) within the previous 24 hours * Likelihood of forbidden concomitant therapy such as vascular surgery, coronary artery bypass graft (CABG), valve replacement, or carotid endarterectomy (CEA) * Evidence of cerebral herniation * Subjects with confounding neurological diseases such as dementia * Subjects with CADASIL, Moya Moya, or carotid dissection * Subjects who have experienced a stroke within the previous 3 months (Note: subjects who have recently experienced a TIA, but whose premorbid mRS prior to their stroke is 0-2, will be allowed to enter the study) * Evidence from admission imaging tests of infarction involving \>1/3 of MCA territory, or entire ACA territory involvement, or internal carotid artery (ICA) occlusions without coexisting separate occlusion of the middle cerebral artery (because of the difficulty distinguishing between chronic and acute ICA lesions in such subjects) * Pathology other than cerebral infarction on any admission imaging tests (e.g. ICH or SAH, AV malformation, cerebral aneurysm, or cerebral neoplasm) * Current or previous known excessive alcohol use or dependence * Current known illicit drug use or dependence * Participation in a previous clinical study within 30 days * Subjects unlikely to be able and willing to attend all study follow-up visits * Any other conditions which in the opinion of the investigator deem the subject ineligible for inclusion * Females who are pregnant or intend to become pregnant or subjects (male and female) who do not agree to use effective contraception for 3 months after end of treatment
