Data highlight key pharmacokinetic properties of serdexmethylphenidate that are instrumental to its consistent and smooth release of d-MPH
CELEBRATION, Fla., Jan. 11, 2022 (GLOBE NEWSWIRE) -- KemPharm, Inc. (NasdaqGS: KMPH), a specialty pharmaceutical company focused on the discovery and development of proprietary prodrugs, announced today that research involving serdexmethylphenidate (SDX), the company’s proprietary prodrug of d-methylphenidate (d-MPH), will be featured in two poster presentations during the American Professional Society of ADHD and Related Disorders 2022 Annual Conference (APSARD 2022) being held virtually January 13-16, 2022. Both posters will be presented by Rene A. Braeckman, Ph.D., Vice President, Clinical Development for KemPharm and will be accessible to registered meeting attendees beginning January 13th.
SDX is the primary active pharmaceutical ingredient in AZSTARYS®, a once-daily product for the treatment of ADHD in patients aged six years and older, approved by the U.S. Food and Drug Administration in March 2021, and being commercialized by Corium, Inc. SDX is also the basis of several other development-stage products being developed by KemPharm, including KP879 (Stimulant Use Disorder) and KP1077 (Idiopathic Hypersomnia). The U.S. Drug Enforcement Agency (DEA) has classified SDX as a Schedule IV controlled substance, which is a lower schedule than all other currently available methylphenidate-based products.
The first poster, titled, “Mass Balance and Metabolic Pathway Following Oral Administration of [14C]-Serdexmethylphenidate, a Novel Prodrug of d-Methylphenidate,” reported data from an open-label, single radiolabeled–dose, nonrandomized study in eight healthy adult male subjects which evaluated the absorption, metabolism, and excretion of SDX following oral administration of radiolabeled 60 mg [14C]-SDX Cl (molar equivalent to 30 mg d-MPH HCl). Results from the study demonstrated that mass balance was achieved following administration of SDX, which was converted to d-MPH without forming novel major metabolites. The research also affirmed that conversion of SDX to d-MPH likely occurs within the lower gastrointestinal tract.
The second poster, titled, “Dose Proportionality and Effects of Food on the Pharmacokinetics of Single-Entity Serdexmethylphenidate (SDX),” reported on two studies involving SDX, which examined the dose proportionality of SDX-derived d-MPH after single doses of 20, 40, or 60 mg of SDX Cl and the effects of food on the pharmacokinetics (PK) of SDX-derived d-MPH after administration of 60-mg SDX Cl capsules. Results from the studies concluded that key PK measures of SDX appeared to increase in a dose-proportional manner with an increase in SDX dose and that food did not impede the production or absorption of SDX-derived d-MPH.
“The research being presented at APSARD 2022 highlights important PK properties of SDX that are believed to be instrumental in the prodrug’s ability to enable a consistent and smooth release of d-MPH,” said Travis Mickle, Ph.D., President and CEO of KemPharm. “The results of these studies suggest that SDX produces a dose-proportionate effect, is not impacted by the presence or lack of food, and is fully absorbed, metabolized and excreted following oral administration. For prescribers, these attributes are recognized as key factors in converting patients to AZSTARYS.”
The studies to be presented at APSARD 2022 were sponsored by KemPharm. The posters will be available for viewing via the conference’s “e-poster” platform on January 13th and viewing will remain open until 30 days post-meeting. Following the conference, the posters will be added to “Publications & Posters” in the News & Publications section of the Company’s website at http://www.kempharm.com.
