A Safety and Efficacy Study of Intravenous (IV) Elezanumab Assessing Change in Neurologic Function in Adult Participants With Acute Ischemic Stroke
A Randomized, Double-Blind, Placebo-Controlled Proof-of-Concept Study to Assess the Safety and Efficacy of Elezanumab in Acute Ischemic Stroke
Stroke is one of the leading causes death and major functional disability worldwide. Treatment options for acute stroke are limited with many patients having residual neurologic impairment. The purpose of this study is to evaluate the safety and efficacy of elezanumab and assess change in neurologic function in participants following an acute ischemic stroke.
Elezanumab is an investigational drug being developed for the treatment of acute ischemic stroke. This 52-week study is "double-blinded', which means that neither the participants nor the study doctors will know who will be given elezanumab and who will be given placebo (does not contain treatment drug). Participants will be assigned to one of two groups, called treatment arms. Participants in one arm will receive elezanumab and participants in the other arm will receive placebo. There is a 1 in 2 chance that participants will be assigned to placebo. Approximately 120 subjects will be enrolled in 45 sites worldwide.
Participants will be randomized to elezanumab or placebo by intravenous (IV) infusion within 24 hours of "last known normal" (time when the participant was last known to be without signs and symptoms of the current stroke) and every 4 weeks thereafter for 48 weeks for a total of 13 doses.
There may be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of elezanumab will be checked by medical assessments, blood tests, evaluation of side effects, and completion of questionnaires.

- Able to randomize within 24 hours of last known normal.
- National Institute of Health Stroke Scale (NIHSS) total score of 7 to 21, inclusive.
- Participants or their legally authorized representative confirms that prior to index stroke, no significant impairment in participant's ability to perform activities of daily living without assistance.

---|---|---|
National Institutes of Health Stroke Scale (NIHSS) Total Score During the Treatment Period
Time Frame: Week 0 through Week 52
|
The National Institutes of Health Stroke Scale (NIHSS) is a neurological examination used to quantitatively measure the severity of acute stroke by evaluating impact of cerebral infarction on level of consciousness, gaze, visual field, facial palsy, motor ability of arm and leg, limb ataxia, sensation, language, dysarthria, and extinction/inattention.
Domains are scored on a scale of 0 to 2, 0 to 3, or 0 to 4, for a total range of 0 -42 points with higher scores indicating impairment.

Week 0 through Week 52

Measure Description |
Time Frame |
---|---|---|
Responder Status based on Modified Rankin Scale (mRS)
Time Frame: Week 0 through Week 52
|
The mRS is used to assess participant's disability and functional dependence.
It is a 6-point scale ranging from 0 (no symptoms) to 5 (severe disability), with additional rating of 6 if the participant is deceased.
