CORALVILLE, Iowa, Nov. 12, 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 September 30, 2015. 

Travis C. Mickle, Ph.D., President and CEO of KemPharm, stated, "We have advanced on several fronts since our last quarterly update, the most significant being the completion of the human abuse liability program for KP201/APAP. We believe the results demonstrate that the prodrug design of KP201/APAP offers the ability to limit opioid exposure when misused, either intranasally (with and without APAP), intravenously, smoked, or orally at high doses, when compared to non-prodrug formulations.  We look forward to presenting the full KP201/APAP human abuse liability data package as part of the NDA, which we expect to submit to the FDA as early as by the end of 2015."

Dr. Mickle continued, "While the clinical and regulatory progress of KP201/APAP has been and continues to be a primary driver for KemPharm, we believe our product candidate pipeline offers numerous value-enhancing opportunities for the company. Recently, we strengthened our prodrug pain franchise with the addition of an APAP-free formulation of KP201 and an IR formulation of our oxycodone prodrug, KP606, to our pipeline of product candidates. We believe that, beginning in 2017, these additions may position us to file at least one new NDA each year through 2019. This highlights the potential of our LAT prodrug technology to rapidly advance multiple product candidates from early to late stage clinical development."

Dr. Mickle concluded, "Filing the NDA for KP201/APAP before year-end is our top priority, and we expect to meet this milestone.  Based on guidance obtained at our May 2015 pre-NDA meeting with the FDA, we believe the results from the human abuse liability program may support FDA Category 1 and Category 2 abuse-deterrent language in the KP201/APAP product label.  If approved by the FDA, KP201/APAP has the potential to be the first abuse-deterrent opioid to have such language in its product label, as well as potentially being the first immediate release, abuse deterrent hydrocodone/APAP option for acute pain."

KP201/APAP Human Abuse Liability Program Design and Data Review:

The KP201/APAP human abuse liability program was designed by KemPharm to assess key abuse-deterrence criteria as specified by the FDA.  The program included three clinical trials, KP201.A01, KP201.A02 and KP201.A03, as well as three distinct trials designed to evaluate the tamper-resistant properties of KP201/APAP.

Results from the 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, indicated that KP201/APAP resulted in lower exposure to hydrocodone at the two highest dose levels for the trial, as well as lower incidence of hypoxia across the same dosage levels, in each case compared to Norco®, suggesting the potential for improved safety.

Results from the KP201.A02 intranasal human abuse liability trial, which was designed to determine the relative bioavailability, abuse potential, and safety of equivalent doses of crushed and intact KP201/APAP as compared to Norco®, indicated that KP201/APAP, when insufflated, reduces peak hydrocodone exposure (Cmax), delays the time to achieve peak exposure (Tmax), and significantly decreases in exposure to hydrocodone (AUC0-2h) at early time points typically associated with an increased safety risk.

Data from the KP201.A03 intranasal human abuse liability trial, which was designed to compare the amount of hydrocodone released from KP201 and from hydrocodone bitartrate (HB) (both without APAP) after insufflation, demonstrated a statistically significant reduction in Cmax, a delay in Tmax, and a significant decrease in total exposure to hydrocodone especially at early time points typically associated with increased drug liking, abuse and safety. 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.

Lastly, results from three distinct trials designed to evaluate the tamper-resistant properties of KP201/APAP indicated that KP201 remains mostly intact in its inactive prodrug form when being subjected to various chemical manipulation techniques used commonly by opioid abusers. The trials demonstrated that efforts to extract and hydrolyze KP201/APAP were less efficient compared to HB/APAP tablets. Under the more than 1,000 conditions tested, KP201/APAP released less hydrocodone compared to the hydrocodone released from the HB/APAP tablets in every case, usually only yielding the inactive prodrug, KP201. Additionally, KP201/APAP is difficult to prepare for injection and it does not appear to be possible to smoke either KP201 or KP201/APAP.

KemPharm plans to present the FDA with the full KP201/APAP human abuse liability data package as part of its NDA under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act for KP201/APAP as early as the end of 2015. Post-NDA filing, KemPharm plans to conduct additional trials with KP201 to further explore the overdose protective properties of KP201 at high oral doses as exhibited in the KP201.A01 oral human abuse liability trial.

Q3 2015 Financial Results:

KemPharm's net loss for the three months ended September 30, 2015, was $9.7 million, or $0.68 per basic and diluted share, compared to a net loss of $7.1 million, or $3.00 per basic and diluted share, for the same period in 2014. The increase in net loss period-to-period is primarily due to a $1.0 million increase in research and development costs primarily related to KP201/APAP, a $1.1 million increase in general and administrative costs associated with increased personnel-related costs due to increased headcount and stock-based compensation and an increase in non-cash interest expense of $0.5 million for the three months ended September 30, 2015.

As of September 30, 2015, KemPharm had cash and cash equivalents of $59.0 million, which was an increase of $48.7 million compared to cash and cash equivalents of $10.3 million as of December 31, 2014, as a result of KemPharm's initial public offering in April 2015, and a decrease of $5.2 million compared to cash and cash equivalents of $64.2 million as of June 30, 2015, primarily due to KemPharm's continuing product development activities.
