Facilitated percutaneous coronary intervention versus primary percutaneous coronary intervention: design and rationale of the Facilitated Intervention with Enhanced Reperfusion Speed to Stop Events (FINESSE) trial

Background

Percutaneous coronary intervention (PCI) has emerged as the strategy of choice in reestablishing effective flow in occluded infarct-related arteries in patients with acute myocardial infarction (MI) if it can be administered in a timely fashion. Patients who enter the catheterization laboratory with Thrombolysis In Myocardial Infarction (TIMI) grade 3 blood flow in the infarct-related vessel have better clinical outcomes than patients presenting with impaired flow. We hypothesize that a strategy of early pharmacologic reperfusion therapy with abciximab alone or in conjunction with reduced-dose reteplase, followed by PCI will improve the outcome of patients eligible for primary PCI.

Study design

The Facilitated Intervention with Enhanced Reperfusion Speed to Stop Events (FINESSE) study is a 3000-patient, prospective, multicenter, randomized, double-blind, placebo-controlled trial. The study is designed to compare the efficacy and safety of early administration of reduced-dose reteplase and abciximab combination therapy or abciximab alone followed by PCI with abciximab alone administered just before PCI for acute MI. Patients will be randomized to one of these 2 facilitated PCI treatments or primary PCI in a 1:1:1 fashion. The primary efficacy end point of FINESSE is the composite of all-cause mortality or post-MI complications within 90 days of randomization. The primary safety outcome assessment will be Thrombolysis In Myocardial Infarction (TIMI) major bleeding.

Conclusions

The FINESSE study will answer important questions regarding the efficacy and safety of “upstream” medical therapy followed by planned intervention for patients with ST-elevation MI, potentially expanding the population eligible for a primary PCI approach. This study will also provide insight as to which facilitated regimen (reteplase/abciximab combination therapy or abciximab monotherapy) provides the best balance of efficacy and safety.
