Post-marketing Study of Cilostazol (Cilostazol Stroke Prevention Study 2)

Phase 4

Completed

• Conditions: Cerebral Infarction
• Interventions: Drug: Cilostazol; Drug: Aspirin

• Registration Number: NCT00234065
• Lead Sponsor: Otsuka Pharmaceutical Co., Ltd.

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).

2	Aspirin	Aspirin

Primary Outcome Measures

Name	Time	Method
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

Name	Time	Method
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])
Number of Patients With First Occurrence of Ischaemic Cerebrovascular Disease	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	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	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.
