About this study

Official title: Prospective, Randomized Trial of 3 Rapamycin-Eluting Stents With Different Polymer Coating Strategies For The Reduction of Coronary Restenosis (ISAR-TEST-3)

The purpose of this study is to evaluate the efficacy of 3 different rapamycin-eluting-stent platforms to reduce coronary artery reblockage after stent implantation

Read the detailed description

Coronary artery reblockage remains still a drawback of percutaneous coronary interventions even in the era of drug-eluting stents (DES). DESs working principle consists of the delivery of controlled amounts of antiproliferative agents at the local level, which results in the suppression of neointimal proliferation, the main cause of lumen re-narrowing after stent implantation. At present, several DES platforms have been developed and evaluated for clinical use. They differ between them with regard to the stent type, anti-proliferative drug, presence of polymers employed for drug storage and modification of drug-release kinetics as well as type of polymer used for this purpose. Although their mid-term efficacy has been well-established, there is an ongoing debate on the potential of an increased incidence of late stent thrombosis, particularly after discontinuation of thienopyridine therapy, as well as of delayed onset of restenosis or catch-up phenomenon with DESs. Based on animal and human pathological data, investigators have linked the above-mentioned concerns to the presence of polymers in DESs, which have a proinflammatory and prothrombinogenic potential, and sometimes may induce a hypersensitivity reaction. This trial will compare the anti-restenotic efficacy of the permanent polymer (PP), biodegradable polymer (BP) and polymer-free (PF) rapamycin-eluting stents in patients with coronary artery disease. Cypher stent (PP) is a stainless steel stent coated with sirolimus with use of permanent polymers while the ISAR stent is a rough surface stainless steel stent which allows not only polymeric coating (for example biodegradable polymer, BP ISAR stent) but also coating without the need of polymer (PF ISAR stent) in the cath lab.

Questions about this trial

What is this clinical trial studying?

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 2 inclusion and 8 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 11 Jan 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Germany. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

in-stent late luminal loss (time frame: at 6 to 8-month follow-up angiogram). 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 NCT00350454, which also lists 13 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 11 Jan 2008.
