NCT02730455

Brief Summary

The primary objective of the study is to assess the clinical effects of natalizumab versus placebo in acute ischemic stroke on clinical measures of functional independence and activities of daily living. The secondary objective of the study is to explore dose and exposure response and the clinical treatment effects of natalizumab versus placebo in acute ischemic stroke on the following: measures of independence, activities of daily living, neurologic function, quality of life, cognition, and safety and tolerability

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Composite Global Measure of Functional Disability Excellent Outcome at Day 90

    The composite global measure of functional disability excellent outcome was based on a score of 0 or 1 on the modified Rankin Scale (mRS) and a score of \>=95 on the Barthel Index (BI). mRS measures independence, rather than neurological function, with specific tasks pre- and post-stroke. The scale consists of 7 grades, from 0 to 6, with 0 corresponding to no symptoms and 6 corresponding to death. BI consists of 10 items that measure a participant's daily functioning, specifically the activities of daily living and mobility. The items include feeding, moving from wheelchair to bed and returning, grooming, transferring to and from a toilet, bathing, walking on a level surface, going up and down stairs, dressing, and maintaining continence of bowels and bladder. The scores for each of the items are summed to create a total score of 0 to 100. The higher the score, the more "independent" the participant is.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of supratentorial acute ischemic stroke defined by LKN ≤24 hours prior to study treatment initiation.
  • Score of 5 to 23 points, inclusive, on the NIHSS at Screening for subjects initiating treatment ≤9 hours from LKN. Note: NIHSS eligibility must be confirmed within 60 minutes prior to randomization.
  • Score of 5 to 15 points, inclusive, on the NIHSS at Screening for subjects initiating treatment \>9 to ≤24 hours from LKN. Note: NIHSS eligibility must be confirmed within 60 minutes prior to randomization.
  • Prior to index stroke, patient was able to perform basic activities of daily living without assistance: dressing, eating, walking, bathing, and using the toilet.
  • For those subjects who underwent a cranial MRI, there is at least 1 acute infarct with a diameter of ≥2 cm on baseline brain diffusion-weighted imaging.

You may not qualify if:

  • Lacunar or isolated brainstem or cerebellar stroke based on clinical assessment and available acute imaging studies performed under the standard of care.
  • Severe stroke defined by imaging criteria based on either one of the following:
  • Alberta Stroke Program Early CT (ASPECT) score of 0 to 4 based on head CT or
  • Acute infarct volume on MRI diffusion weighed imaging greater than or equal to 70 mL
  • Seizure at the onset of stroke.
  • Known history of prior treatment with natalizumab.
  • Known history of active viral hepatitis B or C.
  • Signs and symptoms of active or acute infection.
