Evaluation of Myocardial Effects of MTP-131 for Reducing Reperfusion Injury in Patients With Acute Coronary Events — EMBRACE  

STEMI Clinical Trial

Official title: A Phase 2a Trial to Evaluate the Safety, Tolerability and Efficacy of Intravenous MTP-131 on Reperfusion Injury in Patients Undergoing Primary Percutaneous Coronary Intervention and Stenting for ST-segment Elevation Myocardial Infarction Infarction

Status Completed

Clinical Trial Summary

The EMBRACE-STEMI trial was a Phase 2a prospective, multicenter, multinational randomized, double-blind, placebo-controlled study designed to assess the safety, tolerability, and efficacy of IV administered elamipretide (also known as MTP-131, or Bendavia) on a background of standard-of-care therapy for reduction of reperfusion injury in patients with first time acute, anterior wall ST-segment elevation myocardial infarction (STEMI).

Clinical Trial Description

The EMBRACE-STEMI trial was a Phase 2a prospective, multicenter, multinational randomized, double-blind, placebo-controlled study designed to assess the safety, tolerability, and efficacy of IV administered elamipretide on a background of standard-of-care therapy for reduction of reperfusion injury in patients with first time acute, anterior wall STEMI.

Patients were randomized to receive either an infusion of elamipretide at 0.05 mg/kg/hr or an identically appearing placebo administered as an IV infusion at 60 mL/hr. The infusion began at least 15 minutes but no more than 1 hour prior to the anticipated reperfusion event and continued through approximately 1 hour following re-establishment of blood flow through the culprit vessel.

The reduction of reperfusion injury, or infarct size, was estimated using the area under the curve (AUC) of the serum creatine kinase (CK) isoenzyme, as well as using magnetic resonance imaging (MRI) performed on the Day 4±1 and on Day 30±7 (both MRI assessments measured infarct size and the ratio of infarct size to myocardial mass). The analyses of cardiac MRI data were performed for both the primary endpoint population and also in all patients who had adequate Day 4/Day 30 cardiac MRI studies.

After completion of the percutaneous coronary intervention (PCI) and stenting, patients received standard medical treatment. ;
