Xenoport, Inc. - Special Call

To discuss the preliminary top-line XP23829 Phase 2 clinical trial results

XenoPort, Inc. Announces Positive Phase 2 Study Results for XP23829 as a Potential Treatment for Patients with Psoriasis

XenoPort, Inc. announced positive preliminary top-line results from its Phase 2 clinical trial of XP23829 as a potential treatment for moderate-to-severe chronic plaque-type psoriasis. XP23829 met its primary endpoint in both 800 mg once daily and 400 mg twice daily doses, demonstrating statistically significant improvements in percent change from baseline to week 12 in Psoriasis Area and Severity Index (PASI) score. XP23829 is a patented prodrug of monomethyl fumarate (MMF) in a novel oral formulation that was designed to potentially offer physicians and patients an effective, better tolerated and easier to use therapeutic option to currently available fumarate products. Description of the Trial: This randomized, double-blind, placebo-controlled Phase 2 clinical trial of XP23829 was conducted in 33 sites in the United States in subjects with moderate-to-severe chronic plaque-type psoriasis. Two hundred eligible subjects were randomized to placebo or one of three treatment arms of XP23829: 400 mg or 800 mg once daily (QD) or 400 mg twice daily (BID). The 12-week treatment period included a three-week titration period followed by nine weeks of treatment at the targeted dose. There was a washout phase of up to four weeks prior to randomization for subjects who were previously taking systemic agents for the treatment of psoriasis. Treatment assignment was stratified based on prior biologic use and approximately 35% of randomized subjects had previous experience with biological treatments for their psoriasis. The primary endpoint of the study was the percent change from baseline to week 12 in PASI score. XP23829 was safe and generally well tolerated. There were no deaths or life-threatening adverse events. No subjects met the safety discontinuation criteria and the majority of treatment emergent adverse events were non-serious and mild or moderate in severity. Diarrhea adverse event rates were consistent with other drugs in the fumaric acid ester class ranging from 22% to 40% in the XP23829 treatment groups compared with 15% for placebo. Other treatment emergent adverse events occurring at an incident rate of greater than or equal to 10% were nausea, abdominal pain, vomiting and headache. The incidence of flushing in the XP23829 dose groups was similar to placebo. Gastrointestinal events were the most frequent adverse event leading to withdrawal during XP23829 treatment. There were two treatment emergent serious adverse events assessed as possibly related to treatment with XP23829: acute cholecystitis and enterocolitis. Both subjects recovered. No subjects experienced Grade 3 or Grade 4 lymphopenia. Less than 5% of subjects in any XP23829 treatment group reached Grade 2 lymphopenia and less than 15% reached Grade 1 at any visit. Lymphocyte levels in all subjects experiencing lymphopenia returned to within normal limits after treatment.
