  Purpose
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).

Cerebral Infarction Drug: Cilostazol Drug: Aspirin Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Post-marketing Study of Cilostazol: Study to Confirm Efficacy in Preventing Recurrent Cerebral Infarction in Comparison With Aspirin

Primary Outcome Measures:
  • Numbers of Patients With First Occurence of Stroke [ Time Frame: 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:
  • Number of Patients With First Recurrence of Cerebral Infarction [ Time Frame: From start of treatment to end of follow-up period (mean follow-up periods : 29 months [STANDARD DEVIATION 16, range 1-59 months]) ]
  • Number of Patients With First Occurrence of Ischaemic Cerebrovascular Disease [ Time Frame: 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 the first occurrence of transient ischaemic attack. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.

  • Number of Deaths From Any Cause [ Time Frame: 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.

  • Number of Patients With First Occurrence of a Composite Endpoint of Stroke, Haemorrhagic Events, or Cardiovascular Events [ Time Frame: 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, subarachnoid haemorrhage, transient ischaemic attack, angina pectris, myocardial infarction, heart failure, or haemorrhage requiring hospital admission. The evaluation committee, whose members were unaware of patients' treatment assignment, adjudicated all trial endpoints.
