About this study

Official title: A Randomized, Active-Controlled,Blinded-Endpoint and Parallel Group Pilot Trial Comparing the Antiplatelet Effects of Ginkgo Diterpene Lactone Meglumine Injection Plus Aspirin Versus Aspirin Alone in Patients With Acute Ischemic Stroke

This study evaluates the addition of Ginkgo Diterpene Lactone Meglumine Injection to aspirin in the treatment of acute ischemic stroke.Half of patient will receive Ginkgo Diterpene Lactone Meglumine Injection(25mg once/day D1-D14) and aspirin(300mg loading dose,then 100mg once/day D2-D14) in combination, while the other half will receive aspirin(300mg loading dose,then 100mg once/day D2-D14).

Read the detailed description

The GDPRS trial is a prospective, randomized, single-centre, open-label, active-controlled, blinded-endpoint trial (a PROBE design concerning clinical trial). A total of approximately 40 patients (18 years≤Age≤ 80 years) with acute ischemic stroke (NIHSS < 12), who can be treated within 72 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) given in a total dose of 300 mg on the first day, followed by 100 mg once/day from Day 2 to Day 14. 2) the other group will receive a 300 mg loading dose of Aspirin on the day of randomization, followed by Aspirin 100 mg once/day from Day 2 to Day 14. 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 4 visits including the day of randomization, 24 hours after the first anti-platelet agents,Day 14±2days and Day 90±7days. The antiplatelet effects will be analyzed in total subjects. The trial is anticipated to complete in 6 months from the first subject recruitment , with 40 subjects recruited. A Data and Safety Monitoring Board (DSMB) will regularly monitor safety during the study. The trial has been approved by IRB(Institutional Review Board) /EC(Ethics Committee) in Renji hospital,Shanghai Jiaotong University School of Medicine.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Ginkgo Diterpene Lactone Meglumine Injection and Acetylsalicylic acid in people with Ischemic Stroke, run by RenJi Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ARU on day 14 (time frame: 14 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2017.
