NDA Filing for Potential New ADHD Treatment, KP415, Accepted by FDA; KemPharm Eligible to Receive $5 Million Milestone Payment from Gurnet Point Capital

Corium, GPC’s portfolio company, to lead all commercialization activities for KP415

Celebration, FL – May 4, 2020 – KemPharm, Inc. (Nasdaq: KMPH), a specialty pharmaceutical company engaged in the discovery and development of proprietary prodrugs, today confirmed that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for its investigational product candidate, KP415.  Per the definitive collaboration and license agreement (the “License Agreement”) between KemPharm and an affiliate of Gurnet Point Capital (GPC), KemPharm is eligible to receive a regulatory milestone payment of $5 million within thirty (30) days following FDA acceptance of the KP415 NDA.

KP415 is KemPharm’s product candidate for the treatment of attention deficit hyperactivity disorder (ADHD), which contains serdexmethylphenidate (SDX), KemPharm’s prodrug of d-methylphenidate (d-MPH).  Since KP415 contains SDX, which is a new molecular entity (NME), the FDA review guidance for NMEs is ten (10) months from the date of acceptance, which could lead to a potential action (PDUFA) date in March 2021.

In addition, KemPharm also announced that Corium, Inc. (Corium) will lead all commercialization activities for KP415, if approved.  Corium is a portfolio company of GPC focused on the development, manufacture and commercialization of specialty pharmaceutical products.  Corium is led by Perry Sternberg, its President and CEO, who is a biotechnology and pharmaceutical industry leader with more than 25 years of commercial experience across a wide range of therapeutic areas in diverse markets.  Prior to joining Corium, Mr. Sternberg served a dual role at Shire Plc (Shire) as the Head of U.S. Commercial for seven therapeutic area business units, as well as the Chief Commercial Officer/Head of the Neuroscience Division, before the acquisition of Shire by Takeda Pharmaceutical Corporation Limited in early 2019.

“We are pleased that the FDA has accepted the KP415 NDA, and we now look forward to working with the team at GPC to advance the regulatory review process towards a potential approval as early as March 2021,” said Travis C. Mickle, Ph.D., President and CEO of KemPharm.  “In addition to the regulatory activities, we are thrilled to have the opportunity to benefit from Perry’s leadership and Corium’s commercialization expertise to bring this new treatment to market, following FDA approval.”

Mr. Sternberg stated, “The advances KemPharm is making in the treatment of ADHD are exciting. There are several unmet needs with existing treatment options, which we believe KP415 has the potential to address, bringing meaningful benefits to physicians, patients and their families. The team at Corium is energized to be working with KemPharm to advance KP415 towards a potential approval and launch.”

In September 2019, KemPharm entered into the License Agreement with an affiliate of GPC for the exclusive worldwide rights to develop, manufacture and, if approved, commercialize KemPharm’s product candidates containing SDX, including KemPharm’s ADHD product candidates, KP415 and KP484.  In addition to the $5 million regulatory milestone payment for acceptance of the KP415 NDA, the License Agreement also provides for a regulatory milestone payment within thirty (30) days after approval of the KP415 NDA.

About KP415:

KP415 consists of SDX co-formulated with immediate-release d-MPH and is designed to address unmet needs with the most widely-prescribed methylphenidate ADHD treatments, including earlier onset of action and longer duration of therapy, while avoiding unnecessary spikes in d-MPH concentrations that may be associated with adverse events.  In addition, results from the various Human Abuse Potential trials for the SDX component of KP415 suggest that the prodrug alone may have lower abuse potential than relevant d-MPH comparators.
