AbstractAs a consequence of acute ischemia and reperfusion in patients with acute ST elevation myocardial infarction, calcium overload inside myocytes not only affects myocardial contraction, relaxation, and myocyte recovery following reperfusion, but also may be related to myocyte necrosis and fatal arrhythmia. MCC-135 is the first in a new class of agents that reduce intracellular calcium overload. Pre-clinical and early clinical studies yielded promising results for patients with ST elevation myocardial infarction. The Evaluation of MCC-135 for Left Ventricular Salvage in Acute MI (EVOLVE) study is a Phase 2a, multicenter, randomized, double-blind, placebo-controlled clinical trial of 2 new doses of MCC-135 (4.5 mg/kg/48 hours and 9.0 mg/kg/48 hours) as adjunct therapy for preservation of left ventricular function and reduction of infarct size in patients undergoing primary percutaneous coronary intervention (PCI) for electrocardiographically moderate-large ST elevation myocardial infarction. The primary endpoint will be left ventricular ejection fraction on Day 5 post myocardial infarction as determined by single photon emission computed tomography (SPECT). Secondary endpoints will include SPECT and echocardiographic assessments, serum cardiac markers, clinical outcomes, and safety measures at specific time points through Day 30 post myocardial infarction. Follow-up clinical and safety assessments will be continued until Day 180. The rationale, design, and methods of the EVOLVE study are described in this paper, along with 2 sub-studies, involving a comparison of pre- and post-PCI measurements with either SPECT or echocardiography, to examine myocardial salvage and the time course of changes in myocardial infarction size and left ventricular function.
