Revenues for the quarter were $10.4 million, compared to $0.4 million for the same period in 2011. Net loss for the first quarter was $9.1 million, compared to a net loss of $17.2 million for the same period in 2011. At March 31, 2012, XenoPort had cash and cash equivalents and short-term investments of $85.0 million.    

Business Highlights

• In January 2012, Regnite^® (gabapentin enacarbil) Extended-Release Tablets received marketing approval in Japan for the treatment of moderate-to-severe primary restless legs syndrome (RLS). Astellas Pharma Inc. holds exclusive rights to develop and commercialize Regnite in Japan, Korea, the Philippines, Indonesia, Thailand and Taiwan and paid XenoPort $10.0 million for the achievement of this milestone. In April 2012, the Central Social Insurance Medical Council, which is responsible for recommending the National Health Insurance price for pharmaceutical products in Japan, approved the reimbursement price of 98.50 yen per 300 mg tablet of Regnite. The approved daily dose of Regnite for the treatment of RLS is 600 mg.
• XenoPort completed three Phase 1 clinical trials of arbaclofen placarbil (AP) that are intended for inclusion in a potential 505(b)(2) new drug application (NDA) filing with the U.S. Food and Drug Administration (FDA) for the treatment of spasticity in patients with multiple sclerosis (MS) or spinal cord injury (SCI). These trials were a renal impairment study, a comprehensive food effect study and a pharmacokinetic bridging study. Preliminary results from the bridging study indicate that the exposure to R-baclofen after dosing of 45 or 30 mg of AP twice a day does not exceed that produced by the highest-approved dose of racemic baclofen (20 mg four times a day).
• XenoPort was awarded U.S. Patent 8,148,414 for "Prodrugs of Methyl Hydrogen Fumarate, Pharmaceutical Compositions Thereof, and Methods of Use." The patent is directed to the XP23829 compound and analogs and formulations thereof. XP23829 is a prodrug of methyl hydrogen fumarate, also known as monomethyl fumarate (MMF). The term of the patent runs until 2029, subject to potential patent term extensions under the Hatch-Waxman Act.

Ronald W. Barrett, Ph.D., chief executive officer of XenoPort, stated, "We are pleased with the approval and pricing of Regnite in Japan, and we thank Astellas for all of its efforts to soon make Regnite available to RLS patients in Japan. We are also pleased with the progress that we are making in our AP program, which includes our ongoing pivotal Phase 3 efficacy and six-month, open-label safety studies in MS patients with spasticity. In particular, the successful Phase 1 bridging study provided information that we believe is critical to a potential 505(b)(2) NDA for AP for the treatment of spasticity in MS and SCI patients."

Dr. Barrett continued, "We continue to make progress on our development program for our novel fumarate analog, XP23829. We demonstrated XP23829 and related compounds were effective in an animal model of psoriasis. We believe our efforts, which included conducting a Pre-IND meeting with the FDA in March, remain on track to file an investigational new drug (IND) application with the Division of Neurology Products for XP23829 later this quarter. Following clearance of the IND by the FDA, the first Phase 1 clinical trial is intended to examine the safety, tolerability and pharmacokinetics of four formulations of XP23829 designed to have different drug release mechanisms and/or time profiles. Our goal is to create a best-in-class fumaric acid ester-based medicine for the potential treatment of relapsing-remitting MS and/or psoriasis."

XenoPort First Quarter 2012 Financial Results

Net sales for the first quarter of 2012 for Horizant^® (gabapentin enacarbil) Extended-Release Tablets, as recorded by GlaxoSmithKline (GSK), were $1.3 million. Pursuant to the terms of XenoPort's collaboration agreement with GSK, XenoPort's share of losses from the Horizant joint profit and loss (P&L) statement will be forgiven up to a maximum of $10.0 million. XenoPort's share of joint P&L losses totaled approximately $7.5 million as of March 31, 2012. Accordingly, for the three months ended March 31, 2012 and 2011, XenoPort recorded no net revenue from unconsolidated joint operating activities.

Collaboration revenue for the quarter was $10.4 million, compared to $0.4 million for the same period in 2011. The increase in collaboration revenue for the first quarter of 2012 was due to the recognition of a $10.0 million milestone payment from Astellas in connection with the approval of Regnite in Japan.

Research and development expenses for the first quarter of 2012 were $12.2 million, compared to $9.9 million for the same period in 2011. The increase in expenses for the first quarter of 2012 was principally due to increased net costs for AP, primarily due to increased clinical costs; and increased net costs for XP23829, primarily due to increased toxicology and manufacturing costs; partially offset by decreased office and facilities overhead costs; and decreased net costs for XP21279, primarily due to decreased clinical costs.

Selling, general and administrative expenses remained relatively constant at $7.4 million for the first quarter of 2012, compared to $7.8 million for the same period in 2011.

Net loss for the first quarter of 2012 was $9.1 million, compared to a net loss of $17.2 million for the same period in 2011. Basic and diluted net loss per share was $0.26 for the first quarter of 2012, compared to $0.49 for the same period in 2011.
