XenoPort Reports Third Quarter Financial Results Announces Encouraging Pharmacodynamic Data from Previous XP23829 Phase 1 Trial Business Wire SANTA CLARA, Calif. -- November 7, 2013 XenoPort, Inc. (Nasdaq: XNPT) announced today financial results for the third quarter and nine months ended September 30, 2013. Revenues for the third quarter were $2.5 million, compared to $0.4 million for the same period in 2012. Net loss for the third quarter was $18.8 million, compared to a net loss of $16.8 million for the same period in 2012. At September 30, 2013, XenoPort had cash, cash equivalents and short-term investments of $74.3 million. XenoPort Third Quarter Events Since the start of the third quarter: *XenoPort reported favorable preliminary results from two Phase 1 clinical trials and three 13-week toxicology studies of XP23829, a novel fumaric acid ester compound that is a prodrug of monomethyl fumarate (MMF). The first healthy-subject Phase 1 study assessed the pharmacokinetics, safety and tolerability of multiple doses of two different oral formulations of XP23829, as well as the approved dose of TECFIDERA^® (dimethyl fumarate; DMF). The second Phase 1 study examined the metabolism and distribution of radiolabeled XP23829 in healthy subjects. The toxicology studies, each of which included a DMF control arm, were conducted in three different animal species. XP23829 is being developed for the potential treatment of relapsing forms of multiple sclerosis and/or psoriasis. *XenoPort announced the inclusion of gabapentin enacarbil in treatment guidelines published by the International Restless Legs Syndrome Study Group and the Willis-Ekbom Disease (WED) Foundation. Additional Results from Previous Phase 1 Trial of XP23829 XenoPort also announced today encouraging pharmacodynamic data from its previous Phase 1, randomized, double-blind, placebo-controlled, multiple ascending dose study of two formulations of XP23829 in healthy adult subjects dosed for up to 12 days. Compared to pre-dosing baseline, XP23829 dosed once or twice a day selectively reduced blood lymphocytes and increased blood eosinophils when assessed after 12 days of dosing. Individual subject end-of-treatment lymphocyte and eosinophil counts were within normal limits with few exceptions. There were no subjects with post-treatment lymphocyte counts below 500 per microliter. Lymphocyte counts returned to near baseline levels when assessed eight to ten days after the last dose. These effects were not observed in placebo-dosed subjects, and there was no effect of XP23829 on other monitored blood cell populations. Ronald W. Barrett, Ph.D., chief executive officer of XenoPort, stated, “The mechanism of action of fumaric acid esters is complex, but generally believed to involve modulation of the immune system. Studies in psoriasis and multiple sclerosis patients indicate that FUMADERM ^ (dimethyl fumarate and monoethyl fumarate salts) and TECFIDERA reduce blood lymphocytes, with the maximal effect occurring after many months of dosing. Both products are also known to cause transient minor increases in blood eosinophils. Though our previous study of XP23829 was small, necessitating caution in interpreting results, we are intrigued by certain aspects of the data – the rapid onset and reversibility of the XP23829 effect on lymphocytes observed in the study and the observation that once-a-day dosing had similar effects as twice-a-day dosing on modulation of these two biomarkers. These results suggest that future studies of XP23829 should include examination of once-a-day dosing as well as lower doses that may be well-tolerated and effective as a consequence of the potential rapid onset of immune modulation.” Dr. Barrett continued, “In the last quarter, we believe that we made considerable progress in our core value-driving activities – advancing the development of XP23829 and executing on our focused plan to commercialize HORIZANT and demonstrate its value to patients and our stockholders. Though we have only completed the first full quarter of our launch of HORIZANT after the drug supply stock-out of our previous partner, we believe we have already seen several encouraging signs that our efforts are impacting sales in the regions where we are promoting HORIZANT.” XenoPort Third Quarter and Nine-Month Financial Results Revenues for the third quarter and nine months ended September 30, 2013 were $2.5 million and $5.1 million, respectively, compared to $0.4 million and $21.1 million for the same periods in 2012. Revenues in the third quarter and nine months ended September 30, 2013 were principally due to XenoPort’s acquisition of the HORIZANT business on May 1, 2013, which resulted in the company’s first commercial sales of HORIZANT during the second quarter of 2013. HORIZANT net product sales for the third quarter and nine months ended September 30, 2013 were $2.0 million and $3.7 million, respectively. The decline in revenues for the nine months ended September 30, 2013 compared to the same period in 2012 was primarily due to the recognition of a $10.0 million milestone payment from Astellas Pharma Inc. in connection with the approval of REGNITE^® (gabapentin enacarbil) Extended-Release Tablets in Japan in 2012 and the recognition of a $10.0 million contingent payment from GlaxoSmithKline (GSK) in connection with the first commercial sale of HORIZANT by GSK for the management of postherpetic neuralgia in adults in 2012. Research and development expenses for the third quarter of 2013 were $6.0 million, compared to $9.4 million for the same period in 2012. The decrease in research and development expenses in the three months ended September 30, 2013 compared to the same period in 2012 was principally due to decreased net costs for arbaclofen placarbil (AP) development and manufacturing and decreased personnel costs primarily related to decreased headcount and decreased non-cash stock-based compensation. Research and development expenses for the nine months ended September 30, 2013 were $29.6 million, compared to $32.3 million for the same period in 2012. The decrease in research and development expenses in the nine months ended September 30, 2013 compared to the same period in 2012 was principally due to decreased net costs for AP development and decreased personnel costs primarily related to decreased headcount and decreased non-cash stock-based compensation, partially offset by increased net costs for XP23829, primarily related to clinical, manufacturing and consulting costs. Selling, general and administrative expenses for the third quarter and nine months ended September 30, 2013 were $14.9 million and $41.5 million, respectively, compared to $7.8 million and $22.8 million for the same periods in 2012. The increase in selling, general and administrative expenses in the third quarter and nine months ended September 30, 2013 compared to the same periods in 2012 was principally due to costs related to the commercialization and promotion of HORIZANT, specifically increased professional fees, which included contract sales force costs and marketing costs, as well as increased personnel costs. Net loss for the third quarter of 2013 was $18.8 million, compared to a net loss of $16.8 million for the same period in 2012. Net loss for the nine months ended September 30, 2013 was $66.7 million, compared to a net loss of $33.9 million for the same period in 2012. Basic and diluted net loss per share were both $0.39 in the third quarter of 2013 versus basic and diluted net loss per share of $0.41 for the same period in the prior year. For the nine-month period ended September 30, 2013, basic and diluted net loss per share were both $1.41 versus basic and diluted net loss per share of $0.90 for the same period in 2012.

HORIZANT IMPORTANT SAFETY INFORMATION INDICATION: HORIZANT^® (gabapentin enacarbil) Extended-Release Tablets are indicated for the treatment of moderate-to-severe primary Restless Legs Syndrome (RLS) in adults. Effects on Driving HORIZANT may cause significant driving impairment. Patients should not drive until they have enough experience on HORIZANT to know if it impairs their driving. Patients’ ability to assess their driving competence and degree of somnolence caused by HORIZANT can be imperfect. Somnolence/Sedation and Dizziness HORIZANT causes somnolence/sedation and dizziness. Patients should not drive or operate other complex machinery until they have enough experience on HORIZANT to know if it impairs their ability to perform these tasks. Lack of Interchangeability with Gabapentin HORIZANT is not interchangeable with other gabapentin products because of differing pharmacokinetic profiles. The same dose of HORIZANT results in different plasma concentrations of gabapentin relative to other gabapentin products. The safety and effectiveness of HORIZANT in patients with epilepsy have not been studied. Suicidal Behavior and Ideation HORIZANT is a prodrug of gabapentin, an antiepileptic drug (AED). AEDs increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. As a prodrug of gabapentin, HORIZANT also increases this risk. Patients treated with any AED for any indication should be monitored for new or worsening depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Anyone considering prescribing HORIZANT must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Patients, caregivers, and families should be informed that HORIZANT increases the risk of suicidal thoughts and behavior and should be advised of the need to be alert for new or worsening signs of and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts of self-harm. Behaviors of concern should be reported immediately to healthcare providers. Drug Reaction With Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including gabapentin. HORIZANT is a prodrug of gabapentin. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, and/or lymphadenopathy, in association with other organ system involvement, such as hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis sometimes resembling an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its expression, other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, the patient should be evaluated immediately. HORIZANT should be discontinued if an alternative etiology for the signs or symptoms cannot be established. Discontinuation of HORIZANT When discontinuing HORIZANT, patients with RLS receiving 600 mg or less once daily can discontinue the drug without tapering. If the recommended dose is exceeded, the dose should be reduced to 600 mg daily for 1 week prior to discontinuation to minimize the potential of withdrawal seizure. Tumorigenic Potential In an oral carcinogenicity study, gabapentin enacarbil increased the incidence of pancreatic acinar cell adenoma and carcinoma in male and female rats. The clinical significance of this finding is unknown. ADVERSE REACTIONS The most common adverse reactions for patients with RLS receiving HORIZANT 600 mg, 1,200 mg, and placebo, respectively, were somnolence/sedation (20%, 27%, and 6%), dizziness (13%, 22%, and 4%), headache (12%, 15%, and 11%), nausea (6%, 7%, and 5%), and fatigue (6%, 7%, and 4%). A daily dose of 1,200 mg provided no additional benefit compared with the 600-mg dose, but caused an increase in adverse reactions. DRUG INTERACTIONS Gabapentin enacarbil is released faster from HORIZANT Extended-Release tablets in the presence of alcohol. Consumption of alcohol is not recommended when taking HORIZANT. HORIZANT taken in conjunction with morphine causes increased somnolence/sedation, dizziness, and nausea. USE IN SPECIAL POPULATIONS Pregnancy and Lactation Based on animal data, HORIZANT may cause fetal harm. There are no adequate and well-controlled studies of HORIZANT in pregnant women. HORIZANT should be used during pregnancy only if potential benefit justifies potential risk to fetus. HORIZANT is converted to gabapentin, which is secreted into human milk. Discontinue nursing or discontinue HORIZANT, taking into account the importance of HORIZANT to the mother, due to potential for adverse reactions in nursing infants. Renal Impairment In patients with RLS who have compromised renal function, HORIZANT should be dosed based upon creatinine clearance (CrCl): 30 to 59 mL/min, start with 300 mg per day and increase to 600 mg as needed; 15 to 29 mL/min, use 300 mg per day; <15 mL/min, use 300 mg every other day. HORIZANT is not recommended for use in patients receiving hemodialysis.
