XenoPort Provides Highlights of HORIZANT Prescription Trends and Update on Development for Alcohol Use Disorder

SANTA CLARA, CA - January 11, 2015 - XenoPort (NASDAQ:XNPT) today reported an update on prescription trends and further development of HORIZANT® (gabapentin enacarbil) Extended-Release Tablets, including feedback from the U.S. Food and Drug Administration (FDA) on development for treatment of alcohol use disorder (AUD).

HORIZANT prescription trend highlights include:

 

    The number of nation-wide prescribed tablets for the 13 weeks ending December 19, 2014 was 1,256,082, an increase of 18% compared to the prior 13 weeks ending September 19, 2014 and an increase of 95% over the 13-week period ending December 20, 2013.*

 

    The rolling four-week average of prescribed tablets for the week ending December 19, 2014 was 100,742.* The current wholesale acquisition cost (WAC) price is $7.69 per tablet.

 

    During the third quarter of 2014, XenoPort increased its field sales force of NeuroHealth Sales (NHS) Specialists from approximately 40 to 65 representatives. The number of prescribed tablets for the 13 weeks ending December 19, 2014 in the territories occupied by the new NHS Specialists was 227,897, an increase of 46% compared to the 13 weeks ending June 27, 2014, which was prior to the addition of the new NHS Specialists.*

Vincent J. Angotti, XenoPort’s chief operating officer, stated, “Our efforts to educate doctors and patients about HORIZANT are clearly having an impact. With the addition of the new NHS Specialists who were deployed during the third quarter of 2014, we believe that prescriptions will continue to experience strong growth in 2015. Given HORIZANT’s demonstrated promotional sensitivity and the fact that we believe the healthcare providers we are currently calling on represent a small percentage of the prescription market potential of HORIZANT, we plan to continue to explore means to expand our promotional efforts.”


XenoPort also today provided the following update on the development of HORIZANT as a potential treatment for AUD:

 

    In the fourth quarter of 2014, representatives from XenoPort and the National Institutes for Alcohol Abuse and Alcoholism (NIAAA) conducted a pre-investigational new drug (IND) meeting with the FDA. Based on the meeting, XenoPort believes that the FDA has accepted the NIAAA’s design of the proposed pivotal clinical trial of HORIZANT as a potential treatment for AUD. In addition, XenoPort believes that it may be possible for this clinical trial to support a potential supplemental new drug application (sNDA) for HORIZANT if the results from the trial are robust and compelling and if there is additional confirmatory evidence from the literature or other sources to support the findings.

 

    The NIAAA submitted an IND for HORIZANT as a potential treatment for AUD in December 2014 and has indicated that, upon clearance of the IND, the NIAAA’s proposed pivotal clinical trial will begin in the first half of 2015 and that the results may be available by the end of 2016.

Ronald W. Barrett, PhD, chief executive officer of XenoPort, stated, “HORIZANT sales are growing, and we believe that we have just begun to unlock the potential value of this product for our stockholders. We have also consummated agreements with Reckitt Benckiser Pharmaceuticals, Inc. (now Indivior PLC) for arbaclofen placarbil (AP) and with the NIAAA for HORIZANT that we believe could lead to important use of XenoPort-discovered compounds to treat AUD - a serious disorder that deserves better treatment options.”

Dr. Barrett continued, “We also continue to make good progress on the development of XP23829. XenoPort believes that XP23829 could potentially be a best-in-class fumaric acid ester compound with a potentially better tolerability profile than other drugs in this class. We remain on track and continue to expect to obtain the top-line results of our Phase 2 XP23829 moderate-to-severe chronic plaque-type psoriasis study in the third quarter of this year. We believe the study will provide key data on the effect of dose and dosing regimen on efficacy and tolerability. In advance of the results, we are focused on preparing to advance XP23829 into Phase 3 development by mid-2016 in psoriasis and/or relapsing forms of multiple sclerosis (MS).”

About HORIZANT

HORIZANT, discovered and developed by XenoPort, was approved in the United States in July 2011 for the treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults and in June 2012 for the management of postherpetic neuralgia (PHN) in adults. XenoPort assumed responsibility for commercialization of HORIZANT in the United States in May 2013 after return of all product rights from its former partner. The most common adverse reactions for adult patients with moderate-to-severe primary RLS receiving HORIZANT were somnolence/sedation, dizziness, headache, nausea and fatigue. The most common adverse reactions for adult patients with PHN taking HORIZANT were dizziness, somnolence/sedation, headache, nausea and fatigue.


HORIZANT is protected by a composition-of-matter patent that runs to 2022, with potential patent term extension likely into 2025.

About Alcohol Use Disorder (AUD)

AUD affects about 17 million people in the United States and has an estimated societal cost of approximately $225 billion each year, primarily from lost productivity, but also from healthcare and property damage costs.

About XP23829

XP23829, an experimental drug discovered and currently under development by XenoPort, is a fumaric acid ester compound that is a prodrug of monomethyl fumarate (MMF). Fumaric acid ester compounds have shown immuno-modulatory and neuroprotective effects in cell-based systems and preclinical models of disease. XenoPort has completed a single-dose, a multiple-ascending dose and single-dose radiolabeled metabolism and disposition trials of XP23829 in healthy subjects. It has also completed 13-week toxicology studies in three species. XP23829 is in the fumaric acid ester class of compounds that include TECFIDERA, which was approved in March 2013 by the FDA for the treatment of patients with relapsing forms of MS, and FUMADERM, which is approved in Germany and widely used for the treatment of patients with psoriasis.

XP23829 is protected by a composition-of-matter patent that currently has an expiration date of 2029.

About XenoPort
