Filter by:This is a parallel-arm, double-blind, placebo-controlled study with a screening phase that includes a 28-day run-in phase to establish baseline seizure frequency, followed by a 24-week, randomized, placebo-controlled phase. After completion of the randomized, placebo-controlled phase, participants may enter a 48-week, long-term, extension phase during which they will receive open-label treatment with vatiquinone.
Mitochondrial Diseases are rare progressive, multi-system, often early fatal disorders affecting both children and adults. KH176 is a novel chemical entity currently under development for the treatment of inherited mitochondrial diseases, including MELAS (Mitochondrial Encephalomyopathy, Lactic acidosis, and Stroke-like episodes), Leigh's Disease and Leber's Hereditary Optic Neuropathy (LHON). KH176 is a potent intracellular redox modulating agent targeting the reactive oxygen species which are important in the pathogenesis of disorders of mitochondrial oxidative phosphorylation. After demonstrating a favourable safety profile in the pre-clinical testing, the safety, tolerability and pharmacokinetic and pharmacodynamic characteristics of the compound will now be evaluated in healthy male subjects in this trial
EPI-743 in Leigh syndrome participants that participated in previous EPI743-12-002 (NCT01721733) study.
The purpose of this study is to evaluate the effects of EPI-743 in children with Leigh syndrome on disease severity, neuromuscular function, respiratory function, disease morbidity and mortality and disease associated biomarkers.
