KemPharm Announces Issuance of Two Additional U.S. Patents Governing KP415 and KP484 - Seite 2

About KP415 and KP484:

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.

KP484 is KemPharm’s co-lead clinical development candidate being developed for the treatment of ADHD in patients that respond best when a very long duration of therapy is required. Similar to KP415, KP484 is based on SDX. Preclinical and clinical studies of KP484 have demonstrated that the prodrug may produce a longer duration release of d-MPH compared to the most prescribed methylphenidate products. KP484 has the potential to be the first new methylphenidate-based product being developed with the intent to address the specific needs of the adult ADHD population.
