CORALVILLE, Iowa, March 28, 2016 (GLOBE NEWSWIRE) -- KemPharm, Inc. (NASDAQ:KMPH) announced today that its Investigational New Drug (IND) application for KP511, KemPharm’s prodrug of hydromorphone, has been accepted by the U.S. Food and Drug Administration (FDA). KP511 is being developed as an abuse-deterrent, extended-release (ER) prodrug for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatments are inadequate (KP511/ER). KemPharm expects to initiate human clinical trials of KP511 in the second quarter of 2016.
Travis Mickle, Ph.D., President and Chief Executive Officer at KemPharm, said, “We are very pleased that the FDA accepted our IND for KP511 a full week earlier than the required 30 day review cycle and we look forward to initiating human clinical trials of KP511 in the second quarter of 2016. In particular, as part of the clinical trial process, we will investigate whether the molecular structure of KP511 may reduce the risk of oral overdose by a mechanism that is inherent in the prodrug molecule itself.”
KemPharm plans to seek approval of KP511/ER under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act with an anticipated New Drug Application (NDA) submission as early as 2018. The anticipated development program for KP511 is designed to assess the product candidate’s tamper and extraction resistance, intranasal and intravenous abuse potential, as well as the potential to limit oral abuse and/or overdose. KemPharm believes that the potential to reduce the risk of oral overdose may be possible based on the prodrug overwhelming the metabolic pathways required to convert it to hydromorphone at excessive oral doses. Additionally, KemPharm intends to investigate KP511’s potential to improve or reduce opioid-induced constipation, a common side effect of opioid therapy.
KP511 utilizes KemPharm’s Ligand Activated Therapy (LAT) platform technology to create potential abuse-deterrent properties at the molecular level. KemPharm believes that this proprietary design offers the potential to restrict the release of the active hydromorphone component until the prodrug is metabolized following oral administration. KP511/ER is designed to be bioequivalent to currently available ER hydromorphone products.
KemPharm is a clinical-stage specialty pharmaceutical company focused on the discovery and development of proprietary prodrugs to treat serious medical conditions through its LAT platform technology. 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.
