About this study
Official title: Prospective, Randomized, Double-Blind, Placebo-Controlled Trial of the Glycoprotein IIb/IIIa Inhibition With Abciximab in Patients With ACS Undergoing Coronary Stenting After Pretreatment With a High Loading Dose of Clopidogrel (ISAR-REACT-2)
The purpose of this study is to determine whether there is any additional benefit from abciximab administration during percutaneous coronary intervention in patients presenting with acute coronary syndromes after pre-treatment with 600mg of clopidogrel.
Read the detailed description
Although percutaneous coronary interventions (PCIs) are an established therapeutic approach in patients presenting with acute coronary syndrome (ACS), it is still unclear which the best antithrombotic therapy to be applied periprocedurally is. The EPISTENT trial has shown that adding abciximab (a glycoprotein [GP] IIb/IIIa receptor inhibitor) to the therapy with ticlopidine plus aspirin significantly reduces the incidence of ischemic complications (death, myocardial infarction or reinterventions) after coronary stent implantation. Ticlopidine also reduces procedural complications but has a delayed onset of action after coronary stenting and has been replaced by clopidogrel, which provides similar efficacy and is associated with fewer side effects. Experimental studies have shown that a 600 mg loading dose of clopidogrel is safe and acts rapidly leading to a maximal inhibition of platelet aggregation within 2 hours after administration. In the ISAR-REACT trial, a 600 mg loading dose of clopidogrel was well tolerated, and associated with such a low frequency of early complications that the use of abciximab offered no clinically measurable benefit at 30 days. Although patients with ACS have frequently been treated with a "cooling-off" strategy for >48 hours before undergoing PCI, the ISAR-COOL trial demonstrated that patients undergoing PCI within 6-12 hours of presentation with an ACS actually suffer a lower rate of ischemic complications than those for whom an invasive approach is delayed. However, patients with ACS represent a higher risk subset and may need a more potent antithrombotic regimen periprocedurally. Therefore, the results of ISAR REACT, which was performed in low and intermediate risk patients, should not be generalized to high risk patients.
Comparison:
All patients with non-ST-segment elevation acute coronary syndromes who will undergo coronary angiography willing to participate in the trial will receive a loading dose of 600 mg clopidogrel at least 2 hours prior to the procedure. Eligible patients who do not meet the exclusion criteria in whom angiography reveals that PCI is planned will be randomized to receive either abciximab plus low-dose heparin, 70 units/kg, or high dose heparin (140 units/kg) plus placebo.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Abciximab in people with Coronary Disease and Angina, Unstable, run by Deutsches Herzzentrum Muenchen at 5 sites in 3 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 4 inclusion and 11 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 15 Apr 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Germany, Brazil, Netherlands. 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. Some participants in this study may receive a placebo. 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?
Composite rate of death, myocardial infarction, and urgent target vessel revascularization within 30 days (time frame: 30 days). 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 NCT00133003, which also lists 8 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 15 Apr 2008.
