Q2 2015 Corporate Highlights:
CORALVILLE, Iowa, Aug. 13, 2015 (GLOBE NEWSWIRE) -- KemPharm, Inc. (NASDAQ:KMPH), a clinical-stage specialty pharmaceutical company engaged in the discovery and development of proprietary prodrugs, today reported its corporate and financial results for the quarter ended June 30, 2015. In addition, KemPharm today announced positive data from the first of two intranasal human abuse liability clinical trials in accordance with the Company's broader KP201/APAP human abuse liability program. KP201/APAP, KemPharm's most advanced product candidate currently being developed for the treatment of acute moderate to moderately severe pain, consists of KP201 formulated in combination with acetaminophen ("APAP").
This first intranasal trial (KP201.A03) was conducted with KP201, a prodrug of hydrocodone and the active ingredient ("API") in KP201/APAP. This single-center, cross-over pharmacokinetic study was designed to measure the amount of hydrocodone released from the API, KP201, when insufflated (i.e. snorted) without acetaminophen ("APAP"), as compared directly to hydrocodone bitartrate (HB). KP201 demonstrated a statistically significant lowering in peak hydrocodone exposure (Cmax), and a delay in the time to achieve peak exposure (Tmax), as well as a significant decrease in total exposure to hydrocodone (AUClast and AUC 0-4h) especially in the early time points typically associated with increased drug liking and abuse. Secondary endpoints related to drug liking, pupillometry and ease of snorting also showed significant differences between KP201 and HB with KP201 demonstrating lower drug liking, less pupil dilation and higher difficulty of snorting than HB.
Results from the KP201.A03 trial included:
A second intranasal human abuse liability trial (KP201.A02) is currently ongoing and is intended to assess the intranasal abuse potential of the final commercial formulation of KP201/APAP. KemPharm anticipates reporting data from the KP201.A02 trial in the third quarter of 2015. The KP201.A03 and KP201.A02 trials are part of a broader human abuse liability program designed by KemPharm to assess key abuse-deterrence criteria as specified by the U.S. Food and Drug Administration ("FDA").
Travis C. Mickle, Ph.D., President and CEO of KemPharm, stated, "This is a very exciting time for KemPharm as we continue to make significant progress in the clinical and regulatory development of KP201/APAP. Today's results from the KP201.A03 intranasal human abuse liability clinical study indicate that KP201 drastically limits hydrocodone exposure when taken through a route typically associated with abuse, adding to the growing library of favorable data demonstrating the abuse- and tamper-resistant properties of KP201/APAP. We believe this study is the first direct head-to-head comparison of an API for immediate release prescription opioid products to demonstrate such a meaningful difference in opioid exposure, highlighting the inherent benefits of our prodrug technology. Based on guidance obtained at our May 2015 pre-NDA meeting with the FDA, we believe these differences would qualify for Category 2 abuse-deterrent labeling based on the established FDA guidance."
Dr. Mickle continued, "The unique attributes of KP201/APAP were also observed in the results of the recently announced KP201.A01 oral human abuse liability trial. Importantly, data from that study indicated that our prodrug technology may offer an improvement in the safety of the drug when taken in high amounts orally, further supporting the potential for Category 2 abuse-deterrent labeling for KP201/APAP."
Dr. Mickle concluded, "Looking ahead, we anticipate reporting data from the remaining studies in our comprehensive KP201/APAP human abuse liability program – the KP201.A02 intranasal human abuse liability trial and three tamper resistance studies – during the third quarter of 2015. Based on reaching these milestones, and the results of our May 2015 pre-NDA meeting with the FDA, we now anticipate filing the NDA for KP201/APAP with the FDA in the fourth quarter of 2015."
KP201/APAP Clinical and Regulatory Progress
The KP201.A03 trial is part of a broader human abuse liability program designed by KemPharm to assess key abuse-deterrence criteria as specified by the FDA. On June 11, 2015, KemPharm reported positive results from its KP201.A01 oral human abuse liability trial, which was designed to measure hydrocodone exposure, drug likability and the safety of KP201/APAP, as compared to Norco®, when taken orally at 4, 8 and 12 tablet dosages, each of which are much greater than the recommended amount (1 to 2 tablets). Highlights of the trial results included lower exposure to hydrocodone at the highest dose levels for the trial, as well as lower incidence of hypoxia across the same dosage levels, in each case compared to the hydrocodone reference drug, suggesting the potential for improved safety. As expected, liking data was similar at each equivalent dose level.
Remaining components of the human abuse liability program include three nonclinical studies to evaluate the tamper resistance of KP201/APAP (whether the active ingredient can be extracted physically or chemically, abused intravenously or smoked) and a second intranasal human abuse liability clinical trial (KP201.A02) designed to assess the relative pharmacokinetics and drug likability of KP201/APAP compared to Norco®. Results from these studies are expected in the third quarter of 2015.
As announced previously, KemPharm's management held a pre-NDA meeting with the FDA for KP201/APAP on May 20, 2015. Based on this pre-NDA meeting with FDA and the favorable data generated from the KP201.A01 and KP201.A03 trials, KemPharm anticipates submitting an NDA under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act for KP201/APAP to the FDA in the fourth quarter of 2015.
Corporate Highlights and Q2 2015 Financial Results
During the second quarter, KemPharm announced the appointment of Gordon K. "Rusty" Johnson to the new role of Chief Business Officer and the promotion of R. LaDuane Clifton to Chief Financial Officer. These changes are intended to enhance KemPharm's focus on strategic opportunities for KP201/APAP and its pipeline of other prodrug product candidates in development.
Dr. Mickle said, "Creating the role of Chief Business Officer is an exciting milestone for KemPharm, enhancing our focus on strategic opportunities and reflecting our growth into a mature, development-stage, specialty pharmaceutical company. Based on the current status of our product candidate pipeline, we see this management re-alignment as a key element of our business development strategy."
As of June 30, 2015, KemPharm had cash and cash equivalents of $64.2 million, an increase of $54.0 million from March 31, 2015. This increase was due primarily to proceeds from KemPharm's IPO of $59.9 million, net of underwriting discounts and commissions.
KemPharm's net loss for the three months ended June 30, 2015, was $29.8 million, or $2.45 per basic and diluted share, compared to a net loss of $3.6 million, or $1.50 per basic and diluted share, for the same period in 2014. The increase in net loss period-to-period is primarily due to the non-cash fair value adjustment for the Company's derivative and warrant liability of $22.7 million for the three months ended June 30, 2015, as well as an increase in research and development costs for KP201/APAP and an increase in general and administrative costs associated with increased personnel-related costs due to increased headcount, stock-based compensation and costs associated with KemPharm's IPO-related activities.
