First received: January 13, 2009
Last updated: April 7, 2014
Last verified: April 2014
The objectives of this study are to assess the safety, tolerability and local tolerance, and to investigate the plasma levels and terminal elimination half life of MCI-186, and to review the routine clinical and neurological assessments data of MCI-186 in subjects with acute ischemic stroke.

Condition Intervention Phase
Acute Ischemic Stroke (AIS)
Drug: MCI-186
Drug: Placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase IIa, Multi-centre, Randomised, Double-blind, Placebo Controlled, Clinical Study Investigating the Safety, Tolerability and Pharmacokinetics of MCI-186 in Subjects With Acute Ischemic Stroke

Further study details as provided by Mitsubishi Tanabe Pharma Corporation:

Primary Outcome Measures:
  • Number of Participants That Experienced Adverse Events [ Time Frame: 87days ]
    Additional Outcome Measures are included in Tables for Serious Adverse Events and Other Adverse Events to report their numbers and frequency.

Secondary Outcome Measures:
  • Plasma MCI-186 Pharmacokinetics [ Time Frame: 72 hours ]
    The geometric mean values of MCI-186 plasma concentration at the end of the infusion (at 72h) in cohorts 1 and 2 were determined.

  • mRS, NIHSS, Barthel Index [ Time Frame: throughout study ]

Enrollment: 36
Study Start Date: February 2009
Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)

Cohort 2: Edaravone: circa 2000 mg / 72-hour infusion

Other Name: Edaravone
Placebo Comparator: Placebo Group Drug: Placebo

Cohort1:circa 1000mg / 72-hour infusion matching placebo

Cohort2:circa 2000mg / 72-hour infusion matching placebo


Ages Eligible for Study:   40 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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
