Rare diseases and orphan drugs are at the forefront of novel development and groundbreaking research. Almost half of all novel medications approved by the U.S. Food and Drug Administration (FDA) are orphan drugs. Below is the list of important regulatory dates for all orphan drugs for 2023.
Prescription Drug User Fee Act (PDUFA) dates refer to deadlines for the FDA to review new drugs. The PDUFA date is 10 months after the drug application has been accepted by the FDA or 6 months, if the drug is given a priority review designation. As each PDFUA date approaches, CheckRare will be covering the FDA meetings and outcomes.
