Rationale and design of a randomized, double-blind, placebo-controlled trial of 6 versus 12 months clopidogrel therapy after implantation of a drug-eluting stent: The Intracoronary Stenting and Antithrombotic Regimen: Safety And EFficacy of 6 Months Dual

There is clinical equipoise on the issue of optimal duration of dual antiplatelet treatment after percutaneous intervention with DES. The ISAR-SAFE trial aims to assess whether discontinuation of clopidogrel 6 months after DES implantation is noninferior to routine prolongation of such therapy out to 1 year.
