Zevra Therapeutics NDA Review Extended
FDA has extended by three months its review of a Zevra Therapeutics NDA resubmission for arimoclomol, an investigational oral treatment for Niemann-Pick disease Type C (NPC). The new user fee review action target date is 9/21, according to the agency, which also re-affirmed its intent to present the resubmission for discussion at a future advisory committee meeting.
The resubmission was filed in January and reportedly addresses the concerns raised in a 6/2021 FDA complete response letter. “The resubmission includes additional evidence supporting trial metrics, FDA-preferred analyses, and data from multiple additional studies that provide supporting evidence of arimoclomol’s efficacy in clinical and non-clinical settings,” the company says.
NPC is described as an ultra-rare, progressive, and neurodegenerative lysosomal storage disorder characterized by an inability of the body to transport cholesterol and other lipids within the cell, leading to an accumulation of these substances in various tissue areas, including brain tissue. “Those living with NPC lose independence due to physical and cognitive limitations, with key neurological impairments presenting in speech, cognition, swallowing, ambulation, and fine motor skills,” Zevra says.
