Ultragenyx Triheptanoin NDA for Genetic Disorder
Ultragenyx Pharmaceutical has submitted to FDA an NDA for UX007 (triheptanoin) for treating long-chain fatty acid oxidation disorders (LC-FAOD), a group of genetic disorders in which the body is unable to convert long-chain fatty acids into energy. The submission is based on data from a Phase 2 study in 29 patients, a long-term safety and efficacy extension study in 75 patients including 20 patients who were previously naive to UX007, a retrospective medical record review of 20 original compassionate use patients, 67 patients treated through expanded access, and a randomized controlled investigator-sponsored study of 32 patients showing an effect on cardiac function, the company says.
Ultragenyx describes UX007 as a “highly purified, pharmaceutical-grade, medium-chain triglyceride consisting of three 7-carbon fatty acids on a glycerol backbone created via a multi-step chemical process. It is an investigational therapy that directly addresses the deficiencies in LC-FAOD by providing patients with an alternative energy source that can be metabolized to increase intermediate substrates in the Krebs cycle, a key energy-generating process.”
