Soleno NDA Review Extended by 3 Months
FDA has extended by three months its review of a Soleno Therapeutics NDA for DCCR (diazoxide choline) extended-release tablets for treating Prader-Willi syndrome (PWS) in individuals four years and older who have hyperphagia. The new user fee review action target date is 3/27/2025.
The agency says the review extension was necessary after it determined that responses to recent information requests constituted a major amendment to the NDA, according to the company. “The FDA did not cite any safety, efficacy or manufacturing concerns in their correspondence,” it adds.
The company says the hallmark symptom of the disorder is hyperphagia, a chronic and life-threatening condition characterized by feelings of intense, persistent hunger, food pre-occupation, and an extreme drive to seek and consume food, which can severely diminish the quality of life for affected individuals. “Additional characteristics of PWS include behavioral problems, cognitive disabilities, low muscle tone, short stature (when not treated with growth hormone), the accumulation of excess body fat, developmental delays, and incomplete sexual development,” it says.
The submission is based on Phase 3 data that “showed promise” in addressing hyperphagia, as well as several other symptoms such as aggressive/destructive behaviors, fat mass and other metabolic parameters, the company says.
