The PLATINUM Clinical Trial to Assess the PROMUS Element Stent System for

Status Completed

Clinical Trial 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 longer than average-sized.

Clinical Trial 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 The study design is consistent with the draft guidance for industry titled, "Coronary Drug-Eluting Stents - Nonclinical and Clinical Studies" (March 2008).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 Long Lesion study is a sub-trial associated with the PLATINUM Workhorse Randomized Controlled Trial, which is registered under NCT00823212. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
