简要总结
The primary purpose of this study is to determine if a single dose of nerinetide can reduce global disability in people who have had a stroke and are selected for endovascular therapy without the use of a tissue plasminogen activator (alteplase, tenecteplase, or equivalent).
详细描述
This study is a Phase 3, randomized, multicentre, blinded, placebo-controlled, parallel group, single-dose with a single interim analysis. Because AIS (acute ischemic stroke) is a medical emergency, the trial is designed to enable the administration of standard-of-care treatments without delay in order to save the life of the person concerned, restore good health or alleviate suffering.
Participants harboring an acute ischemic stroke who are selected for endovascular revascularization without intravenous or intra-arterial thrombolytic therapy will be given a single, 2.6 mg/kg (up to a maximum dose of 270 mg) intravenous dose of nerinetide or placebo. Outcomes of the main trial will be evaluated throughout a 90 day observation period.
Participants will be followed at 1-Year for the analytic sub-trial for further outcome assessment by telemedicine or telephone interview conducted by individuals blinded to the outcome of the main trial. This sub-trial will be conducted to explore the independent functioning and quality of life at 1-Year.

入选标准
- •Acute ischemic stroke (AIS) selected for emergency endovascular treatment.
- •Age 18 years or greater.
- •Onset (last-known-well) time to randomization time within 12 hours.
- •Disabling stroke defined as a baseline National Institutes of Health Stroke Score (NIHSS):
- •NIHSS > 5 for internal carotid artery (ICA) and M1-middle cerebral artery (MCA) occlusion; or
- •NIHSS > 10 for M2-MCA occlusion.
- •Confirmed symptomatic intracranial occlusion at one or more of the following locations: Intracranial carotid I/T/L, M1 or M2 segment MCA. Tandem extracranial carotid and intracranial occlusions are permitted.

- •Qualifying imaging performed less than 2 hours prior to randomization.
- •Consent process completed as per national laws and regulation and the applicable ethics committee requirements.
排除标准
- •Treated with a tissue plasminogen activator (e.g., alteplase or tenecteplase) within 24 hours before randomization.
- •Determination by the treating physician, based on current treatment guidelines and medical evidence, that treatment with a plasminogen activator is indicated.
- •Large core of established infarction defined as ASPECTS 0-

结局指标
主要结局
Number of Participants With Independent Functioning on the Modified Rankin Scale (mRS), as Defined by a Score of 0-2
时间窗: 90 days
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.
次要结局

- Number of Participants Exhibiting a Worsening of Their Index Stroke.(90 days)
- Number of Participants With Good Neurological Outcome, as Defined by a Score of 0-2 on the NIHSS at Day 90 Post Randomization.(90 days)
