About this study

Official title: PLATINUM: A Prospective, Randomized, Multicenter Trial to Assess an Everolimus-Eluting Coronary Stent System (PROMUS Element™) for the Treatment of up to Two De Novo Coronary Artery Lesions - Small Vessel Sub-trial

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.

Read the 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 The study design is consistent with the draft guidance for industry titled, "Coronary Drug-Eluting Stents - Nonclinical and Clinical Studies" (March 2008).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.

A study testing PROMUS Element Coronary Stent System in people with Coronary Artery Disease, run by Boston Scientific Corporation at 23 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 38 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in United States, Australia, Belgium, France, Japan and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Feb 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Target Lesion Failure (TLF) (time frame: 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01498692, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Mar 2019.
