Brief Summary:
The ESCAPE-NA-1 study is designed to determine the safety and efficacy of the neuroprotectant, Nerinetide (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: Nerinetide (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, Nerinetide, 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 Nerinetide 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 Nerinetide 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 Nerinetide (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. Number of Subjects With mRS Score of 0 to 2 [ Time Frame: 90 Days ]

    Overall number of subjects experiencing a favorable functional outcome 90 days post-randomization, defined as 0 to 2 on the mRS.

    The modified Rankin Scale (mRS) is a valid and reliable clinician-reported measure of global disability that has been widely applied for evaluating recovery from stroke. It is a scale used to measure functional recovery (the degree of disability or dependence in daily activities) of people who have suffered a stroke. mRS scores range from 0 (best outcome) to 6 (worst outcome), with 0 indicating no residual symptoms; 5 indicating bedbound, requiring constant care; and 6 indicating death.

Secondary Outcome Measures :
  1. Number of Subjects With NIHSS Score of 0 to 2 [ Time Frame: 90 Days or the last rating ]

    Number of subjects with good neurological outcome, as defined by a score of 0 to 2 on the NIHSS at Day 90 or the last rating.

    The National Institutes of Health Stroke Scale (NIHSS) is a standardized neurological examination score that is a valid and reliable measure of disability and recovery after acute stroke. Scores range from 0 to 42, with higher scores indicating increasing severity.

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

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.
  6. 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.
  8. Endovascular treatment with declared first endovascular approach as either stent retriever or aspiration device, and intended to be initiated (arterial access) within 60 minutes of baseline/qualifying NCCT and to first recanalization of 90 minutes. Study drug intended to be administered within 60 minutes of the baseline/qualifying NCCT.
  9. Signed informed consent from subject or legally authorized representative or, if required to enable inclusion by applicable national laws and regulations and the applicable independent review boards/Ethics Committee requirements for obtaining consent, from the investigator after consultation with an independent physician who is not otherwise participating in the trial.

Exclusion Criteria:

  1. Evidence of a large core of established infarction defined as ASPECTS 0-4.
  2. Evidence of absence of collateral circulation on CTA (Collateral score of 0 or 1).
  3. Intent to use any endovascular device other than a stent retriever or clot aspiration device or intra-arterial medications as the initial thrombectomy approach.
  4. Intent to use any intravenous thrombolytic other than alteplase if intravenous thrombolysis is planned.
  5. No femoral pulses, very difficult endovascular access or extreme tortuosity of great vessels that is predicted to result in an inability to deliver timely endovascular therapy. Direct common carotid or radial/brachial/axillary access is permissible.

Severe contrast allergy or absolute contraindication to iodinated contrast preventing endovascular intervention, including any contraindications listed in the prescribing information approved by local authorities (e.g., patients with decompensated heart failure as a contraindication for the use of VISIPAQUE™ 270 in Germany).
  9. Clinical history, past imaging or clinical judgment suggests that the intracranial occlusion is chronic or there is suspected intracranial dissection such that there is a predicted lack of success with endovascular intervention.
  10. Prior enrolment in the ESCAPE-NA1 trial or prior receipt of NA-1 for any reason.
