Detailed Description

This trial is a randomized, double-blind, placebo-controlled trial, A total of approximately 70 patients with acute ischemic stroke (5<NIHSS < 24), 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 was diluted with 250ml physiological saline,intravenous drip for about 3 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. The trial is anticipated to complete in 10 months from the first subject recruitment , with 70 subjects recruited. 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

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
