KemPharm Completes KP415 Pre-NDA Meeting with FDA

April 11, 2019 at 4:17 PM EDT

KP415 NDA Filing Anticipated in Late Q2 or Early Q3 2019

Conference Call Scheduled for Today, Thursday, April 11, 2019 at 5:00 p.m. ET

CELEBRATION, Fla., April 11, 2019 (GLOBE NEWSWIRE) -- KemPharm, Inc. (Nasdaq: KMPH), a specialty pharmaceutical company engaged in the discovery and development of proprietary prodrugs, today announced that the Company concluded a pre-New Drug Application ("NDA") meeting with the U.S. Food and Drug Administration ("FDA") for KP415, KemPharm’s investigational attention-deficit/hyperactivity disorder (ADHD) product candidate that contains serdexmethylphenidate (a prodrug of d-methylphenidate) and d-methylphenidate. Held yesterday, the purpose of the meeting was to discuss the Company’s NDA for KP415 and to confirm the clinical and non-clinical requirements for its submission.  

At the pre-NDA meeting, representatives from the FDA reviewed KemPharm’s summary of the data package being prepared for the KP415 NDA submission, including clinical, non-clinical and human abuse potential studies, as well as regulatory elements. Based on the feedback from the FDA, the Company believes its regulatory data package will be sufficient for submission, with acceptance of the filing subject to the FDA's review of the complete package.

“We are pleased with the collaborative tone of our meeting with the FDA, and we now have a solid understanding of the Agency's requirements for our submission,” said Travis C. Mickle, Ph.D., President and Chief Executive Officer of KemPharm. “Based on feedback received during this meeting and from previous correspondences, we are confident in moving forward with our NDA package for KP415, which is on track for submission in late Q2 or early Q3 2019.” 

Dr. Mickle added, “One of the topics discussed with the FDA was the data analysis of the KP415.E01 efficacy trial.  The complete KP415.E01 data package will be included in the NDA and provides additional analyses beyond the previously announced top line data that further support our belief that KP415 elicits an onset of action at 30 minutes and a duration of effect of 13 hours.  In addition, the FDA stated that no additional efficacy study or data is required to assess KP415’s efficacy in treating ADHD.”

KP415 is KemPharm’s prodrug product candidate being developed for the treatment of ADHD. KP415 consists of serdexmethylphenidate (SDX), KemPharm’s prodrug of d-methylphenidate (d-MPH), co-formulated with immediate-release d-MPH.  KP415 is designed to address unmet needs with the most prescribed methylphenidate ADHD treatments, including earlier onset of action and longer duration of therapy. In addition, the results from the Human Abuses Potential program for the SDX component of KP415 suggest that the prodrug may have lower abuse potential than relevant d-MPH comparators.
