Comparison of Intracoronary Versus Intravenous Abciximab in ST-segment Elevation Myocardial Infarction (CICERO) (CICERO)

September 7, 2010 updated by: University Medical Center Groningen

Coronary Versus Intravenous abCiximab Administration During Emergency Reperfusion Of ST-segment Elevation Myocardial Infarction - the CICERO Trial

The primary objective of this study is to investigate whether intracoronary bolus administration of abciximab is superior to intravenous bolus administration in improving myocardial perfusion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The contemporary management of ST-segment elevation myocardial infarction (STEMI) consists of primary percutaneous coronary intervention (PCI) including thrombus aspiration and stenting. There is, however, still a high incidence of impaired post-procedural myocardial perfusion, which is associated with poorer clinical outcomes. Intravenous (IV) administration of the glycoprotein IIb/IIIa inhibitor abciximab during primary PCI plays an important role in the treatment of patients with STEMI. With higher local drug concentrations, abciximab may have additional anti-platelet, anti-thrombotic and anti-inflammatory features. These possible benefits may be obtained by intracoronary (IC) administration of abciximab. Recent small- to medium-scaled studies have suggested that IC administration of abciximab instead of the (IV) route is associated with improved post-procedural myocardial perfusion and a clinically relevant reduction of major adverse cardiac events.

Because of the limited number of patients included in these studies, a larger randomized clinical trial is needed to evaluate the effect of IC abciximab in patients with STEMI. Furthermore, the combined strategy of PCI with thrombus aspiration and IC use of abciximab has not been investigated.

Therefore, the investigators intend to evaluate the effect of IC bolus administration of abciximab compared to IV bolus administration on post-procedural myocardial perfusion as assessed by the extent of ST-segment elevation resolution in patients with STEMI undergoing primary PCI. The study is a single-center, prospective, randomized trial with blinded evaluation of endpoints.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
