Earlier this year iECURE reported that an infant with the rare and deadly liver disease OTC deficiency had a complete response to its experimental gene editing therapy. It is believed to be the time that an infant was treated with an in vivo, liver-directed gene editor. The treatment restored ammonia levels in the child’s blood to normal and the child is off of ammonia scavenger medicines and is eating a normal diet. We spoke to Joe Truitt, CEO of iECURE, about the company’s experimental therapy for OTC, how it works, and its approach to in vivo gene editors.
