Ischemic Stroke, Acute
Conditions
Brief summary
The aim of this study is to evaluate the safety and effectivity of Ginkgo diterpene lactone meglumine injection tn the treatment of acute ischemic stroke
Detailed description
This trial is a randomized, double-blind, placebo-controlled trial, A total of approximately 80 patients (age \> 40 years) with acute ischemic stroke (5\<NIHSS \< 25), who can be treated within 4.5 to 48 hours of symptom onset will be enrolled. Patients fulfilling all of the inclusion criteria and none of the exclusion criteria will be randomized 1:1 into two groups after offering informed content: 1) one group will receive a Ginkgo Diterpene Lactone Meglumine Injection 25mg/5ml,once/day from Day 1 to Day 14（the injection must be added slowly into 0.9% sodium chloride injection diluted to 250 ml , intravenous drip for about 2 hours）, combined with Acetylsalicylic acid (Aspirin) at a dose of 100 mg/d for 90 days;2) the other group will receive the same volume saline injection as placebo for 14 days plus aspirin at a dose of 100 mg per day for 90 days.The primary objective is to assess the anti-platelet effects of Ginkgo Diterpene Lactone Meglumine Injection combined with Aspirin versus Aspirin alone in patients with acute ischemic stroke. The study consists of 3 visits including the day of randomization, Day 14±2days and Day 90±7days.After randomized to 90 + 7 days mRS 0-1 points is the Primary Outcome Measure,evaluate the safety and effectivity of Ginkgo diterpene lactone meglumine injection tn the treatment of acute ischemic stroke.A Data and Safety Monitoring Board (DSMB) will regularly monitor safety during the study. The trial has been approved by Ethics Committee of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients with Modified Rankin Scale (mRS) | 90 days | Proportion of patients with Modified Rankin Scale (mRS) less than or equal to 1 . The mRS scores range from 0 to 6, ranging from perfect health without symptoms to death |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| New vascular events defined as any event of the following: Any stroke (ischemic or hemorrhage) | 90 days | All the new vascular events will be assessed by at least two neurologists based on neuroimaging and clinical feature. When there was disagreement, a third senior neurologist was consulted to reach a consensus decision. |
