Study Description

Brief Summary

The purpose of this study is to investigate the efficacy of cilostazol in preventing recurrence of cerebral infarction and the safety of long-term administration of the drug (100 mg, twice daily) in patients with cerebral infarction (excluding cardiogenic cerebral embolism) in a multi-center, double-blind, parallel-group comparison with aspirin (81 mg, once daily).

Outcome Measures

Primary Outcome Measures

  1. Numbers of Patients With First Occurence of Stroke [From start of treatment to end of follow-up period ( follow-up periods : 29 months [Standard Deviation 16, range 1-59 months])]

    The endpoint in this measure is a composite endpoint of the first recurrence of cerebral infarction, or occurrence of cerebral haemorrhage or subarachnoid haemorrhage. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.

Secondary Outcome Measures

  1. Number of Patients With First Recurrence of Cerebral Infarction [From start of treatment to end of follow-up period (mean follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months])]

    The endpoint in this measure is a composite endpoint of the first recurrence of cerebral infarction or the first occurrence of transient ischaemic attack. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.

  3. Number of Deaths From Any Cause [From start of treatment to end of follow-up period ( follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months])]

    Number of deaths from any cause. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.

Comments Statistical Analysis 1 for Number of Patients With First Occurrence of Stroke
Type of Statistical Test Non-Inferiority or Equivalence
Comments If the upper 95% CI limit for the HR of cilostazol to aspirin was 1.33 (4/3) or lower , cilostazol would be non-inferior to aspirin.
Statistical Test of Hypothesis p-Value 0.0357
Comments The log-rank test was used to verify the superiority of CLZ to ASA only if non-inferiority was verified. The adjusted significance level for the superiority test of the endpoint was set at 0.0471 (two-tailed) according to the O'Brien-Fleming method.
