FDA Wants More Data on Prader-Willi Drug

Share

FDA has told Soleno Therapeutics that an additional controlled clinical trial will be necessary to support an NDA submission for DCCR (diazoxide choline) extended release tablets for treating Prader-Willi Syndrome (PWS). Late last year, the company met with FDA regarding the potential adequacy of data from previous studies with DCCR to support an NDA. Soleno subsequently submitted additional analyses to the agency from the company’s Phase 3 trial, DESTINY PWS (C601).

 

“The data analyses showed statistically significant changes for DCCR compared to placebo in the primary and key secondary endpoints,” Soleno says. “Following its review of the data submitted by Soleno, the FDA informed the Company on 3/5/2021 that an additional controlled clinical trial will be necessary to support an NDA submission for DCCR in PWS.

 

The company says that based on the totality of data generated to date, “we remain confident in DCCR’s potential to address the unmet need for a safe and effective treatment option for PWS patients. We are currently evaluating the appropriate next steps for our DCCR program.”
