Brief Summary:
The ESCAPE-NA-1 study is designed to determine the safety and efficacy of the neuroprotectant, NA-1, in reducing global disability in subjects with major acute ischemic stroke (AIS) with a small established infarct core and with good collateral circulation who are selected for endovascular revascularization.

Condition or disease Intervention/treatment Phase
Stroke, Acute Drug: NA-1, 2.6 mg/kg Drug: Placebo Phase 3

Detailed Description:

Trial Objectives:

The primary objective is to determine the efficacy of the neuroprotectant, NA-1, in reducing global disability in subjects with major acute ischemic stroke (AIS) with a small established infarct core and with good collateral circulation selected for rapid endovascular revascularization.

The secondary objectives are to determine the efficacy of NA-1 in:

  • Reducing functional dependence
  • Improving neurological outcome
  • Improving activities of daily living
  • Reducing mortality rate The leading safety objectives are to determine the effect of administering a dose of 2.6 mg/kg (up to a maximum dose of 270 mg) intravenous (IV) infusion of NA-1 to subject with acute stroke who are selected for endovascular revascularization on serious adverse events (SAEs) and 90-day mortality.

Trial Design:

This study is a Phase 3, randomized, multicentre, blinded, placebo-controlled, parallel group, single-dose design. Subjects harboring an acute ischemic stroke and who are selected for endovascular revascularization in accordance with local institutional practices and who harbor a small established infarct core and with good collateral circulation will be given a single, 2.6 mg/kg (up to a maximum dose of 270 mg) intravenous dose of NA-1 or placebo as soon as they are deemed to have met the enrollment criteria and with the intention of starting administration within 30 minutes of randomization. The randomization will be by stochastic minimization to balance baseline factors.

Primary Outcome Measures :
  1. Modified Rankin Score (mRS) [ Time Frame: 90 Days ]
    Overall proportion of subjects experiencing a favorable functional outcome 90 days post-randomization, defined as 0 to 2 on the mRS

Secondary Outcome Measures :
  1. mRS Shift Analysis [ Time Frame: 90 Days or the last rating ]
    Shift of one or more categories to reduced functional dependence analyzed across the whole distribution of scores on the mRS at Day 90 or the last rating.

  2. NIHSS [ Time Frame: 90 Days or the last rating ]
    Proportion of subjects with good neurological outcome, as defined by a score of 0-2 on the NIHSS at Day 90 or the last rating.

  3. 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 BI at Day 90 or the last rating.

  4. Mortality Rate [ Time Frame: 90 Days ]
    A reduction in mortality rate, as defined by event rate (%) for mortality over the 90-day study period

  5. Functional Independence based on mRS [ Time Frame: 90 Days or the last rating ]
    Proportion of subjects with functional independence, as defined by a score of 0-1 on the mRS at Day 90 or the last rating.

Other Outcome Measures:
  1. EQ-5D-5L [ Time Frame: 90 Days or the last rating ]
    Health-related quality of life, as measured by the EQ-5D-5L at Day 90 or the last rating.

  2. Stroke Volume [ Time Frame: 24 hour follow up ]
    Volume of stroke as measured by MRI. If NCCT was done instead of MRI, Volume of stroke will be derived from hypodense areas.

  3. Test of language function [ Time Frame: 90 Days ]
    Cognitive outcome - The 15-item Boston Naming Test (BNT15)

  4. Test of hemi-spatial neglect [ Time Frame: 90 Days ]
    Cognitive Outcome - Sunnybrook hemi-spatial neglect procedure (SNAP)

  5. Global test of cognitive function. Scale from 0 to 30 points. [ Time Frame: 90 Days ]
    Cognitive outcome - The Montreal Cognitive Assessment (MoCA)

  6. Functional outcome based on mRS [ Time Frame: 30 days ]
    The proportion of subjects experiencing a favorable functional outcome 30 days post-randomization, defined as 0 to 2 on the mRS.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Acute ischemic stroke (AIS) for immediate endovascular treatment
  2. Age 18 or greater.
  3. Onset (last-seen-well) time to randomization time within 12 hours.
  4. Disabling stroke defined as a baseline National Institutes of Health Stroke Score (NIHSS) > 5 at the time of randomization.
  5. Pre-stroke (24 hours prior to stroke onset) independent functional status in activities of daily living with modified Barthel Index (BI) > 90 (95 or 100). Patient must be living in their own home, apartment or seniors lodge where no nursing care is required.

Confirmed symptomatic intracranial occlusion, based on multiphase or dynamic computerized tomographic angiography (CTA), at one or more of the following locations: Intracranial carotid T/L, M1 middle cerebral artery (MCA). Functionally, when defining the M1 or the M2, the bulk of the MCA territory must be ischemic.
  7. Non-contrast computed tomography (NCCT) and CTA (multiphase or dynamic) for trial eligibility performed or repeated at ESCAPE-NA1 stroke centre with endovascular suite on-site.
