OREANDA-NEWS. 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 second quarter ended June 30, 2016, including an update on key regulatory and clinical events involving KemPharm’s product candidate Apadaz™ and KemPharm’s pipeline of other proprietary prodrugs.

On June 13, 2016, KemPharm announced that the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) regarding the New Drug Application (NDA) for Apadaz (benzhydrocodone and acetaminophen), the Company’s investigational abuse-deterrent product candidate for the short term management of acute pain.  KemPharm subsequently requested an End of Review meeting with the FDA, which occurred on August 3, 2016. 

At the End-of-Review (EOR) meeting, the Company and the FDA discussed the issues identified by the FDA in the Apadaz NDA and what KemPharm believes is the potential to achieve a path forward for an Apadaz product label that could include abuse deterrence claims.  The meeting also involved discussions pertaining to abuse deterrence in relation to the broader immediate-release (IR) prescription opioid market, hydrocodone-acetaminophen combination products, and published industry guidance from the FDA concerning the evaluation and labeling of abuse deterrent opioids. 

The Company and the FDA also discussed the proposed short-duration “blister” packaging for Apadaz at the EOR meeting, which was put forth as part of KemPharm’s Major Amendment Request to the Apadaz NDA prior to the June 9, 2016 PDUFA date.  The Company confirmed the information expected for the FDA to complete its review of the amendment.  The short duration blister packaging was proposed in alignment with the recently published Centers for Disease Control and Prevention’s Guideline for Prescribing Opioids for Chronic Pain, which advises that clinicians should prescribe the lowest effective dose of immediate-release opioids and should prescribe no greater quantity than needed for the expected duration of pain severe enough to require opioids.

“KemPharm’s mission today is unchanged – to leverage our unique and highly differentiated Ligand Activated Therapy (LAT) discovery platform to develop proprietary prodrugs that have improved properties over currently approved drugs and address significant medical needs in large, established markets,” said Travis C. Mickle, Ph.D., President and Chief Executive Officer of KemPharm. “While the ongoing effort with the FDA concerning Apadaz has presented a near-term challenge for the company to work through, we view it as a single event against multiple potential new product opportunities that hold considerable promise for KemPharm. Our broad pipeline allows us to move forward with the development of our two most advanced extended-release product candidates – KP511/ER for the treatment of severe pain and KP415 for the treatment of attention deficit hyperactivity disorder – as well as with KP201/IR, our acetaminophen-free immediate release hydrocodone prodrug.”

Dr. Mickle concluded, “Looking ahead, we anticipate initiating the human abuse liability clinical program for KP511/ER and filing Investigational New Drug (IND) applications for KP415 and KP201/IR by year-end. These programs represent the most immediate value-building opportunities for KemPharm, and we are orienting our financial and R&D resources to support their potential for success.  Overall, we believe KemPharm remains well capitalized to advance its full pipeline of product candidates, while we determine the optimal path forward for Apadaz.”

Ligand Activated Therapy (LAT) Prodrug Pipeline Update:
During the second quarter and early third quarter 2016, KemPharm achieved key clinical and regulatory milestones for KP511/ER, KP415 and KP201/IR.  Each of these prodrugs is based on KemPharm’s proprietary LAT discovery platform and is designed to improve one or more of the attributes of the approved comparator drug, such as susceptibility to abuse, bioavailability and safety.

On June 28, 2016, KemPharm reported positive results from its Phase 1 proof-of-concept trial of KP511, the Company’s prodrug of hydromorphone.  In the trial (KP511.101), KemPharm observed comparable hydromorphone exposure between 4 mg Dilaudid™ Oral Liquid and an equimolar 8 mg dose of KP511. KemPharm is developing KP511 as an abuse-deterrent, extended release (ER) formulation (KP511/ER) for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatments are inadequate.  Based on these Phase 1 results, KemPharm plans to initiate a human abuse liability clinical program for KP511/ER to assess the product candidate’s tamper and extraction resistance, its intranasal and intravenous abuse potential, as well as its potential to limit oral abuse and/or overdose. Additionally, KemPharm intends to investigate KP511’s potential to improve or reduce opioid-induced constipation (OIC), a common side effect of opioid therapy.  KemPharm anticipates initiating the KP511/ER human abuse liability program prior to the end of 2016.

On July 14, 2016, KemPharm announced the completion of a Pre-Investigational New Drug (Pre-IND) review of KP415, the Company’s prodrug of d-threo-methylphenidate for the treatment of attention deficit hyperactivity disorder (ADHD).  Based on input received from the FDA, KemPharm expects to file an IND for KP415 before the end of 2016.

In preclinical studies of KP415, KemPharm observed features that it believes could provide significant benefits when compared with other FDA-approved and widely prescribed methylphenidate products. Pharmacokinetic data from preclinical studies suggest that the time to maximum plasma concentration of methylphenidate after oral administration of KP415 is approximately three times longer compared to currently marketed IR methylphenidate. KemPharm believes this potential controlled release attribute of KP415’s molecular structure may allow for convenient, once-daily dosing.  KP415 utilizes KemPharm’s LAT platform technology to potentially enable abuse-deterrent properties at the molecular level which addresses the need for methylphenidate products with abuse deterrent features on the market.

In addition, on July 14, 2016, KemPharm announced the completion of an End-of-Phase 1 (EOP1) review for KP201/IR, KemPharm’s single-entity, benzhydrocodone HCl immediate-release product candidate designed for the treatment of acute pain.  KemPharm believes that KP201/IR may also have abuse deterrent properties. KemPharm requested an EOP1 review for KP201/IR ahead of an anticipated IND submission based on the amount of data, both nonclinical and clinical, generated from the development of Apadaz.  As previously reported, data from KemPharm’s intranasal human abuse liability trial (KP201.A03), which compared hydrocodone exposure following insufflation of benzhydrocodone HCl (KP201) vs. hydrocodone bitartrate (HB), 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, including drug liking Emax, 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.  KemPharm remains encouraged by these findings and anticipates filing an IND for KP201/IR before the end of 2016.

Q2 2016 Financial Results:
KemPharm’s reported net income of $9.8 million, or $0.59  net income per basic share, and ($0.58) net loss per diluted share for the quarter ended June 30, 2016, compared to a net loss of ($29.7) million, or ($2.45) net loss per basic and diluted share, for the same period in 2015. Net income for the quarter ended June 30, 2016, was driven primarily by a $20.8 million decrease in the fair value of KemPharm’s derivative and warrant liability as of June 30, 2016.  Loss from operations for the quarter ended June 30, 2016, was $9.3 million, compared to $6.0 million for the same period in 2015.  The increase in loss from operations period-to-period was primarily due to a $2.2 million increase in research and development expenses primarily related to activity for KP511 and KP415, and an increase in general and administrative costs of $1.1 million, primarily due to an increase in headcount and commercial activities. 

As of June 30, 2016, the total of cash and cash equivalents, restricted cash, marketable securities and long-term investments was $102.6 million, and was a decrease of $8.4 million compared to March 31, 2016.
