NCT01261234

Brief Summary

CAS-CARE study was conducted to evaluate the inhibitory effect of cilostazol, compared to that of other antiplatelet drugs, on in-stent restenosis following carotid artery stenting (CAS) in patients scheduled to undergo CAS. Study design is Multicenter Prospective Ranodomized Controlled Study, rondomized by cilostazol/non-cilostazol group prior to CAS. 900 patients will be enrolled for 2 years and followed 2 years with in-stent restenosis after CAS, evaluated by carotid ultrasound and angiography.

Outcome Measures

Primary Outcomes (1)

  • Presence or absence of in-stent restenosis within 2 years after CAS and time to occurrence

    Difinition of endpoint is 50% or more in-stent restenosis detected by carotid ultrasound or angiopraphy. In cases restenosis does not occur, the final observation point will be used as the final evaluation point.

    2 years

Secondary Outcomes (7)

  • Cardiovascular event, death, hemorrhagic event, in-stent restenosis, new out-stent stenosis, or retreatment of stented artery within 2 yrs

    2 years

  • In-stent restenosis, new out-stent stenosis, or retreatment within 2 years

    2 years

  • hemorrhagic event within 2 years

    2 years

  • stroke within 2 years

    2 years

  • In-stent restenosis, new out-stent stenosis, or retreatment of stented artery, cardiovascular event, or death from any cause within 30 days

    30 days

  • +2 more secondary outcomes

Study Arms (2)

Cilostazol group

EXPERIMENTAL

Continuous administration of cilostazol (unrestricted use of other antiplatelet agents and concomitant drugs)

Drug: Cilostazol or Non-Cilostazol

Non-Cilostazol group

ACTIVE COMPARATOR

Antiplatelet agent other than cilostazol (unrestricted use of concomitant drugs)

Drug: Cilostazol or Non-Cilostazol

Interventions

Cilostazol group administrate 100-200mg/day per oral, unrestricted use of other antiplatelet agents and concomitant drugs.

Also known as: Cilostazol (Pretal) group, Non-Cilostazol (Pretal) group
