Brief summary
The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions. The lesions can be located in vessels that are smaller than average-sized.
Detailed description
The wide-spread use of drug-eluting stents (DES) has evolved as standard of care in de novo lesions. The proposed study will evaluate the safety and effectiveness of PROMUS Element for the treatment of de novo atherosclerotic lesions in native coronary arteries. The study design is consistent with the draft guidance for industry titled, Coronary Drug-Eluting Stents - Nonclinical and Clinical Studies (March 2008). During the trial, thienopyridines must be administered according to the 2007 American College of Cardiology (ACC)/American Heart Association (AHA)/Society for Cardiovascular Angiography and Interventions (SCAI) guidelines, which recommended that clopidogrel (75 mg daily) or ticlopidine (250 mg twice daily) be prescribed after stent implantation for at least 6 months in all patients, and for at least 12 months in patients who are not at high risk of bleeding. For sites in the United States, the use of prasugrel is not allowed as part of the PLATINUM Clinical Trial. For sites in other countries, prasugrel may be prescribed according to its approved dosing in countries in which it is available. For patients taking aspirin daily a loading dose is recommended; for patients who have not been taking aspirin daily, aspirin must be administered as a loading dose. Patients continue to take aspirin indefinitely to reduce the risk of thrombosis. This PLATINUM Small Vessel study is a sub-trial associated with the PLATINUM Workhorse Randomized Controlled Trial, which is registered under NCT00823212.
Interventions
PROMUS Element is a device/drug combination product composed of two components, a device (coronary stent system including a platinum chromium stent platform) and a drug product (a formulation of everolimus contained in a polymer coating)

Defined as any ischemia-driven repeat percutaneous intervention to improve blood flow of the successfully treated target lesion or bypass surgery of the target vessel with a graft distally to the successfully treated target lesion.
Time frame: 30 days
Population: Analysis was intention to treat; all patients in the study underwent clinical follow up to provide the information needed for this endpoint.

Secondary
Target Vessel Failure (TVF)
Target vessel failure (TVF) is defined as any ischemia-driven revascularization of the target vessel, myocardial infarction (MI;Q-wave and non-Q-wave) related to the target vessel or death related to the target vessel. For the purposes of this protocol, if it cannot be determined with certainty whether the MI or death was related to the target vessel, it will be considered a TVF.
Time frame: 12 Months
