Clinical Trial Summary

The purpose of this study is to determine whether nerinetide (NA-1) is effective in reducing global disability in patients with acute cerebral ischemia if administered early after symptom onset.

Description:

Nerinetide (NA-1) is being developed as an emergency drug aimed at reducing global disability in patients with acute cerebral ischemia if administered early after symptom onset.

The primary objective is to determine the efficacy of nerinetide in reducing global disability in patients with acute stroke. The secondary objectives are to determine the efficacy of nerinetide in reducing functional dependence, reducing mortality rate, reducing worsening of stroke, improving neurological outcome and improving activities of daily living.

The leading safety objectives are to determine the effect of administering a target dose of 2.60 mg/kg (up to a maximum dose of 270 mg) IV infusion of nerinetide within three hours of symptom onset by paramedics in the field on serious adverse events and 90-day mortality.

This trial is a multicenter, randomized, double-blind, placebo-controlled, single dose study initiated prehospital in the ambulance. It is being conducted using Emergency Medical Services (EMS) in Canada. Subjects with suspected acute stroke will be identified in the field by trained paramedics using the approved stroke protocol in use by the local EMS system, and further screened for eligibility and approval by an on-call trial physician. The paramedics will administer the study drug. Upon arrival at the emergency department, subjects will receive standard-of-care.

An Independent Data Monitoring Committee will perform safety reviews of the clinical data.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Modified Rankin Scale (mRS) scale	The percentage of responders, using a sliding dichotomy on the mRS	90 days
Secondary	mRS shift analysis	Shift to reduced functional dependence analyzed across the whole distribution of scores on the mRS	90 Days or the last rating
Secondary	Mortality rate	A reduction in mortality as defined by event rate (proportion, expressed as a percentage)	90 Days
Secondary	Worsening of stroke rate	A reduction in proportion of participants with worsening of stroke. Worsening of stroke is defined as progression, or hemorrhagic transformation, of the index stroke as documented in the study CRF that (i) is deemed life-threatening and/or (ii) results in increased disability as gauged by a =4 point increase from lowest NIHSS during hospitalization and/or (iii) results in death.	90 Days
Secondary	National Institutes of Health Stroke Scale (NIHSS)	Proportion of subjects with good neurological outcome, as defined by a score of 0-1 on the NIHSS	90 Days or the last rating
Secondary	Barthel Index	Proportion of subjects with functional independence in activities of daily living, as defined by a score of = 95 on the Barthel Index	90 Days or the last rating
