Official Title: A Phase 2 Randomized, Double-Blind, Placebo-Controlled Crossover Study to Evaluate the Safety, Tolerability, and Efficacy of Subcutaneous Injections of Elamipretide (MTP-131) in Subjects With Genetica

Brief Summary: This is a Phase 2, randomized, double-blind, placebo-controlled crossover study which will enroll up to 36 subjects (anticipated) with genetically confirmed mitochondrial disease who have completed participation in the SPIMM-201 (MMPOWER) study. Subjects will be randomized (1:1) to one of two sequence groups: 4-weeks of treatment with 40 mg elamipretide administered once daily subcutaneously in Treatment Period 1 followed by 4-weeks of treatment with placebo administered once daily subcutaneously in Treatment Period 2 (separated by 4-week washout period), or vice versa
