Agreement May Lead to Addition of New Drug Product Candidate and Indication to KemPharm’s Prodrug Development
Pipeline
CORALVILLE, Iowa, Oct. 04, 2017 (GLOBE NEWSWIRE) -- KemPharm, Inc. (NASDAQ:KMPH), a clinical-stage specialty
pharmaceutical company focused on the discovery and development of proprietary prodrugs, announced today that it has entered into a
technology licensing and assignment agreement with Genco Sciences, LLC (Genco).
Utilizing Genco’s early research-stage proprietary nano-particulate amphetamine technology, KemPharm will focus
on devising an unique prodrug to be developed as a treatment for pediatric Tourette’s syndrome when accompanied by ADHD (attention
deficit hyperactivity disorder). Genco previously received an Orphan Designation letter from the U.S. Food and Drug
Administration’s (FDA) Office of Orphan Products Development for its product candidate for pediatric Tourette’s syndrome.
“Today’s announcement of the license and assignment agreement with Genco provides KemPharm’s discovery and
development team the opportunity to apply our prodrug expertise to a potential orphan-drug area of the ADHD market,” said Travis C.
Mickle, Ph.D., President and Chief Executive Officer of KemPharm. “In a subset of pediatric Tourette’s syndrome patients,
there is a recognized problem of ADHD that requires additional treatment concurrent to treating the symptoms of Tourette’s.”
Under terms of the agreement, KemPharm will be responsible for financing and managing all product
development. In exchange, KemPharm will retain full intellectual property and commercial ownership of any product developed
as a result of this agreement, with Genco eligible to receive certain milestone and royalty-based or value share payments.
Additional details about the agreement were not disclosed.
“KemPharm’s success at creating unique prodrug product candidates in multiple treatment areas allows us to see
real potential for a prodrug to be successful as the basis for treating this rare pediatric disease,” said Subhash Desai, Ph.D.,
Chief Executive Officer of Genco. “By treating the underlying ADHD, we believe we can unlock the door to also treating tics
and/or Tourette’s syndrome to provide an effective therapy for the unmet needs of those affected by this complex neurologic
disorder.”
“Our goal is to discover and develop a prodrug-based therapy that can provide an appropriate and effective
treatment for a rare pediatric disease while also successfully completing the FDA’s regulatory approval process, which may
potentially allow us to seek a Priority Review voucher,” Dr. Mickle continued. “Uniquely, KemPharm’s proprietary LAT prodrug
platform provides an opportunity to receive a voucher under the current guidelines which is an example of another way that prodrugs
can be used to create value. Our agreement with Genco both builds on this platform and potentially adds significant assets to our
development pipeline in ADHD.”
About Tourette’s Syndrome and ADHD
Tourette’s syndrome is an inherited neuropsychiatric disorder with onset in childhood, characterized by the presence of motor and
phonic tics – the treatment goal is managing symptoms to achieve optimum functioning, rather than
eliminating symptoms; not all persons with Tourette's require treatment, and there is no cure nor universally effective
medication.
In 90% of cases, Tourette’s syndrome exists in conjunction with another disorder. The most frequent co-occurring condition in
people with Tourette (63%) is ADHD, though the cause of this association is uncertain.
The Centers for Diease Control and Prevention published a series of statistics related to Tourette’s syndrome in its “A National
Profile of Tourette Syndrome, 2011-2012.” The CDC profile is linked as follows: https://www.cdc.gov/ncbddd/tourette/data.html
