KemPharm Receives NDA User Fee Waiver from FDA

CORALVILLE, Iowa, March 24, 2016 (GLOBE NEWSWIRE) -- KemPharm, Inc. (NASDAQ:KMPH), a clinical-stage specialty pharmaceutical company focused on the discovery and development of proprietary prodrugs, today announced that the U.S. Food and Drug Administration (FDA) has granted a fee waiver and has refunded the full user fee amount of $2,374,200 for its New Drug Application (NDA) filing for KP201/APAP, the Company’s investigational immediate release combination of its hydrocodone prodrug, KP201 (benzhydrocodone hydrochloride), and acetaminophen (APAP), which is currently under priority review by the FDA. The FDA has set a target action date under the Prescription Drug User Fee Act of June 9, 2016.

The fee waiver, which KemPharm requested in accordance with section 736(d)(1)(E) of the Federal Food, Drug and Cosmetic Act, is granted to a small business, as defined by the Small Business Administration, for the first human drug application submitted to the FDA for review.

Travis C. Mickle, Ph.D., President and Chief Executive Officer of KemPharm, commented, “We are pleased to receive this NDA fee waiver for KP201/APAP and look forward to continuing to work with the FDA through the review process. We believe that prodrugs developed using our Ligand-Activated Therapy technology may demonstrate properties that are aligned with the advice of regulatory, physician and patient organizations advocating for responsible measures for managing pain and prescribing opioids, including recommendations that opioid therapy for chronic pain begin with the introduction of immediate-release opioids as a means to reduce the risks associated with long-acting or extended-release opioids.”

KemPharm developed KP201/APAP using the Company’s 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 active parent drug, which can then provide its therapeutic effect.

KemPharm utilizes its LAT platform technology to generate improved prodrug versions of FDA-approved drugs in the high need areas of pain, ADHD and other CNS disorders.
