XenoPort Announces Plan to Focus on its Growing HORIZANT Business and Names Vincent J. Angotti Chief Executive Officer and Director

SANTA CLARA, Calif.--()--XenoPort, Inc. (Nasdaq: XNPT) announced today a strategic shift to focus on and maximize the value of its commercial product, HORIZANT® (gabapentin enacarbil) Extended Release Tablets. As part of this shift, XenoPort will discontinue development of XP23829 on its own and seek to partner this and other high potential development stage assets.

In connection with the decision to focus on commercializing HORIZANT, Ronald W. Barrett, Ph.D., has retired as Chief Executive Officer and as a Director of XenoPort, effective immediately. Vincent J. Angotti, Executive Vice President and Chief Operating Officer, who has spearheaded the commercialization of HORIZANT, has been named Chief Executive Officer and has joined XenoPort’s Board of Directors. Dr. Barrett will continue to work with XenoPort in an advisory role, with a primary focus on ensuring a smooth transition and advising on potential partnering activities for the company’s development stage assets, including XP23829.

Mr. Angotti has nearly 25 years of operations and commercialization experience in both large and start-up specialty pharmaceutical companies. Prior to joining XenoPort in May 2008, Mr. Angotti held several positions with Reliant Pharmaceuticals, Inc., the most recent of which was Senior Vice President of Sales and Marketing. In this senior leadership role, he was responsible for launching a portfolio of products including LOVAZA, leading to the acquisition of Reliant by GlaxoSmithKline in 2008 for $1.7 billion. Prior to Reliant, Mr. Angotti held several positions at Novartis Pharmaceuticals Corporation, most recently as Executive Director, Field Operations. Mr. Angotti received a B.S. from Cornell University and an M.B.A. from Columbia University.

XenoPort also announced that John G. Freund, M.D., has been named Chairman of XenoPort’s Board of Directors. Dr. Freund has been a member of XenoPort’s Board since 1999 and has served as its Lead Independent Director since July 2008.

“On behalf of the Board,” Dr. Freund stated, “I would like to thank Ron for his dedication and many contributions since co-founding XenoPort in 1999, including the discovery, development and approval of HORIZANT. Ron recruited Vince to lead the commercialization of HORIZANT and, together with the management team, they have meaningfully grown HORIZANT sales. The Board is thrilled to welcome Vince to the role of CEO and has confidence he will apply his operational and commercial experience to maximize the value of HORIZANT.”

Mr. Angotti stated, “I am excited by the opportunity to lead the company with our new strategic focus. Since XenoPort’s launch of HORIZANT in mid-2013, we have successfully taken a staged approach to its commercialization. With the recent expansion of our HORIZANT Neuroscience Health Specialist team to 120 representatives in July, I believe we are well positioned to expand our educational efforts and increase access to HORIZANT and thereby meaningfully benefit many more patients.”

HORIZANT Continues to Show Strong Growth

XenoPort noted that HORIZANT continues to show strong growth following the re-launch by XenoPort after reacquisition in May 2013. HORIZANT has achieved the following growth since the second quarter of 2013 with substantially fewer sales representatives than deployed by its former partner:

        2Q13       2Q15       % Change
New Prescriptions*       5,355       14,221       +166%
Total Prescriptions*       9,173       26,271       +186%
Tablets*       377,753       1,379,341       +265%
Net Sales       $1.6 million       $8.2 million       +413%

Expense Reduction

In connection with XenoPort’s strategic shift, the company also announced that it will be implementing a reduction in work force. Restructuring costs, primarily related to compensation and benefit expenses as well as severance costs related to its departing CEO, are expected to be approximately $3.2 million and result in annual future cash savings of approximately $6.7 million. In addition, future expenses will be reduced due to the discontinuation of late-stage development of XP23829. The company ended the second quarter of 2015 with $170.4 million in cash, cash equivalents and short-term investments.


HORIZANT, discovered and developed by XenoPort, was approved in the United States in April 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. 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. In addition, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) is currently funding and conducting a trial of HORIZANT in patients with alcohol use disorder (AUD). XenoPort is supplying the clinical trial material for this trial. If successful, it could lead to a new potential option for the treatment of patients with AUD.
