Clinical Trial Summary

Clinical Trial Description

China has the largest burden of cerebrovascular disease in the world. About 60% to 80% of which are ischemic stroke. In recent years, stroke has replaced heart disease and tumor diseases as the first cause of death and disability in adult population. The primary purpose of this study is to evaluate the efficacy of indobufen treatment in reducing the risk of a 3-month new stroke (any type of stroke, including ischemic stroke and hemorrhagic stroke) for patients with moderate/severe ischemic stroke is not inferior to aspirin therapy. The study is a multicenter, randomized, double-blind, positive drug parallel control and non-inferiority clinical design. Non-inferiority analysis was performed on the primary efficacy analysis, and both intent analysis (ITT) and compliance program set (PPS) were used for analysis. If the indobufen group was confirmed to be non-inferior to aspirin (control group), a superiority analysis was further performed to analyze whether the indobufen was superior to aspirin. At the same time, Kaplan-Meier curves were used to simulate the cumulative risk of stroke (ischemic or hemorrhagic) at 90-day follow-up, and the Cox proportional hazards model was used to calculate the hazard ratio (HR) and 95% confidence interval, Log-rank test was used to evaluate the treatment effect. All statistics will be two-sided with p<0.05 considered significant. All patients who received study drugs and with at least one safety follow-up record will be included in the safety population. The data for safety evaluation included adverse reactions observed during the trial and changes in laboratory data before and after treatment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
