|Acute Cerebral Ischemia||Drug: NA-1 Drug: Placebo||Phase 3|
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 NA-1 in reducing global disability in patients with acute stroke. The secondary objectives are to determine the efficacy of NA-1 in reducing functional dependence, improving neurological outcome, improving activities of daily living, and increasing the proportion of subjects who are candidates for endovascular recanalization therapy.
The leading safety objectives are to determine the effect of administering a target dose of 2.60 mg/kg IV infusion of NA-1 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.

2.60 mg/kg of NA-1 administered as a single 10 minute IV infusion using an ambulatory infusion pump early after stroke symptom onset.
Placebo Comparator: Placebo
Placebo administered as a single 10 minute IV infusion using an ambulatory infusion pump early after stroke symptom onset.
- Modified Rankin Scale (mRS) scale [ Time Frame: 90 days ]The percentage of responders, using a sliding dichotomy on the mRS
- mRS shift analysis [ Time Frame: 90 Days or the last rating ]Shift to reduced functional dependence analyzed across the whole distribution of scores on the mRS
- Proportion of subjects with functional independence [ Time Frame: 90 Days or the last rating ]
Proportion of subjects with functional independence, as defined by a score of a) 0-2 and b) 0-
1 on the mRS
- National Institutes of Health Stroke Scale (NIHSS) [ Time Frame: 90 Days or the last rating ]Proportion of subjects with good neurological outcome, as defined by a score of 0-1 on the NIHSS
- Barthel Index [ Time Frame: 90 Days or the last rating ]Proportion of subjects with functional independence in activities of daily living, as defined by a score of ≥ 95 on the Barthel Index
- Eligibility for endovascular recanalization [ Time Frame: 24 hours ]Proportion of subjects who are deemed to be candidates for endovascular recanalization therapy
