Sodium Nitrite in Acute Myocardial Infarction

April 11, 2018 updated by: Johns Hopkins University

A Safety and Efficacy Evaluation of Sodium Nitrite Injection for the Prevention of Ischemia-Reperfusion Injury Associated With Acute Myocardial Infarction.

The purpose of this study is to determine whether the intravenous infusion of sodium nitrite safely prevents ischemia-reperfusion injury in subjects with acute myocardial infarction resulting in improved left ventricular function.

Detailed Description

Despite reperfusion therapies, significant myocardial injury continues to occur from ischemic-reperfusion injury. Studies in animal models of acute myocardial infarction suggest that an infusion of sodium nitrite, which is nonenzymatically converted to nitric oxide in the setting of ischemia, significantly reduces ischemia-reperfusion injury resulting in smaller infarcts and improved left ventricular function. The objectives of this phase 2 trial are to determine the tolerability and safety of a 48-hour infusion of sodium nitrite in patients with an acute ST-segment elevation myocardial infarction receiving percutaneous coronary intervention. The efficacy of a 48-hour infusion of sodium nitrite will be determined by noninvasive imaging to determine infarct size and left ventricular function.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sodium Nitrite
Dose escalation of sodium nitrite.
Drug: Sodium Nitrite
Subjects assigned to sodium nitrite will receive an initial infusion of 6 nmol/min/kg for 48 hours. After the first six subjects have been enrolled (3 active drug, 3 control) and if there are no dose limiting toxicities, additional cohorts of six subjects each will be randomized to escalating doses of sodium nitrite versus control for a total of 30 subjects.
No Intervention: Open Control
Standard therapy
