FDA Priority Review for KemPharm Pain Drug

Share
FDA has accepted for priority review a KemPharm NDA for KP201/APAP, its investigational drug candidate for the short-term management of acute pain. The agency has set a user fee review action date of 6/9. The immediate release combination of KemPharm's prodrug of hydrocodone, KP201 (benzhydrocodone hydrochloride), and acetaminophen was developed to deter certain common methods of abuse and may also limit excessive opioid exposure in patients and non-medical users compared to currently available hydrocodone combination products, the company says.

The submission requests that FDA recommend that the product be classified as a Schedule III controlled substance.  This request is based on the reduced potential for abuse and the potential safety features attributable to lower exposure levels to hydrocodone as compared to other hydrocodone products, which are designated as Schedule II, according to the company.

KemPharm says it developed KP201/APAP using its proprietary Ligand-Activated Technology (LAT), which creates a new prodrug by chemically attaching one or more molecules, or ligands, to an FDA-approved parent drug.  “Once administered, human metabolic processes, such as those in the gastrointestinal tract, separate the ligand from the prodrug and release the parent drug, which can then provide its therapeutic effect,” it says.
