描述 | Impaired mitochondrial (MITO) energy metabolism plays a key pathogenic role in agerelated degenerative disorders and is centrally involved in organ ischemia/reperfusion injury. Abnormalities of MITO structure and function exist in the failing heart of humans and experimental animals evidenced by hyperplasia, reduced organelle size, diminished rate of ATP synthesis and increased formation of reactive oxygen species (ROS)[3]. Elamipretide (MTP-131), a novel mitochondria-targeting peptide, was shown to reduce infarct size in animals with myocardial infarction and improve renal function in pigs with acute and chronic kidney injury[3]. Long-term therapy with elamipretide improved left ventricular (LV) systolic function, normalized plasma biomarkers and reversed MITO abnormalities in LV myocardium of dogs with advanced heart failure (HF). The results supported the development of elamipretide for the treatment of HF[3]. Patients with heart failure with reduced ejection fraction (ejection fraction, ≤35%) are randomized to either a single 4-hour infusion of elamipretide (0.25 mg/kg/h) or placebo control. Compared with placebo, a significant decrease in left ventricular end-diastolic volume and end-systolic volume occured at end infusion in the highest dose cohort, which demonstrated that a single infusion of elamipretide was safe and well tolerated[4]. |
