Combined oxidative phosphorylation defect type 9
MONDO:0013811Combined oxidative phosphorylation defect type 9 is a rare mitochondrial disease due to a defect in mitochondrial protein synthesis characterized by initially normal growth and development followed by the infantile-onset of failure to thrive, psychomotor delay, poor feeding, dyspnea, severe hypertrophic cardiomyopathy and hepatomegaly. Laboratory studies report increased plasma lactate and alanine, abnormal liver enzymes and decreased activity of mitochondrial respiratory chain complexes I, III, IV, and V.
Also known as: COXPD9, MRPL3 combined oxidative phosphorylation deficiency, combined oxidative phosphorylation deficiency caused by mutation in MRPL3, combined oxidative phosphorylation deficiency type 9, combined oxidative phosphorylation deficiency 9

New drug shows promise for rare energy disorder
Disease control CompletedThis study tested a new drug called OMT-28 in 28 people with primary mitochondrial disease, a condition that affects how cells produce energy. Participants took the drug once daily for 6 months, and researchers measured safety, blood markers of inflammation, and symptoms like fat…

Long-Term safety of mitochondrial drug confirmed in 101 patients
Disease control CompletedThis study looked at the safety of vatiquinone in 101 people with inherited mitochondrial disease who had already taken the drug in a previous study or treatment plan. The goal was to track any side effects until the drug became commercially available or the program ended. Partic…
