Xenon Pharmaceuticals Reports 2016 Financial Results and Provides Corporate Update

March 8, 2017

BURNABY, British Columbia, March 08, 2017 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a clinical-stage biopharmaceutical company, today reported its financial results for the year ended December 31, 2016, and provided a corporate update for 2017.

Dr. Simon Pimstone, Xenon's President and Chief Executive Officer, said, “Our continued progress in 2016 to advance our proprietary pipeline and partnerships has led us to this important inflection point for our company. Over the next few quarters, we expect to reach a number of key milestone events. The most imminent event is the topline data read-out from our XEN801 Phase 2 clinical trial in patients with moderate to severe acne, which is expected later this month. We also look forward to the topline data from the Phase 2 clinical trial of TV-45070 in post-herpetic neuralgia being conducted by Teva expected by mid-year. In addition, we anticipate Genentech advancing GDC-0310 into a Phase 2 clinical trial later this year, as well as our filing of an IND, or IND equivalent, in the fourth quarter for XEN901, a selective inhibitor of Nav1.6 for the treatment of epilepsy disorders.”

Achievements and Anticipated Milestones

Proprietary Pipeline

  • XEN801 is a topical stearoyl Co-A desaturase-1, or SCD1 inhibitor, being developed for the treatment of moderate to severe acne. By targeting a reduction in the size and number of sebaceous glands, thereby reducing sebum production, Xenon believes XEN801 is a promising, novel treatment for acne, which could be better tolerated and without the serious side effects that often limit the use of currently approved retinoid treatments.

    Enrollment of 165 subjects is now complete in the XEN801 Phase 2 clinical trial, which is a randomized, double-blind, multi-center, vehicle-controlled, parallel-group study designed to evaluate the efficacy, safety, tolerability and systemic exposure of XEN801 for the treatment of moderate to severe facial acne. Patients apply a gel formulation of XEN801 (or vehicle placebo) topically to their face once daily in the evening for 12 weeks with a 4-week follow up. The primary efficacy endpoint is the percent change in total (inflammatory and non-inflammatory) lesion count from baseline to week 12. Secondary endpoints include separate efficacy assessments of inflammatory lesion counts, non-inflammatory lesion counts, and Investigator's Global Assessment (IGA) measures. Topline results from the XEN801 Phase 2 clinical trial are expected in the latter part of March.

  • XEN901 is a potent, selective Nav1.6 inhibitor for the treatment of rare infantile epileptic encephalopathies and other forms of epilepsy. XEN901 has demonstrated efficacy against seizures in an animal model of Nav1.6 gain-of-function SCN8A epilepsy as well as models that support the treatment of adult partial onset epilepsy. Xenon expects to file an investigational new drug (IND), or IND equivalent, application in the fourth quarter of 2017.

Partnered Programs

  • TV-45070 is a topical sodium channel inhibitor being developed in collaboration with Xenon’s partner, Teva Pharmaceutical Industries Ltd., for the treatment of neuropathic pain. Teva is currently conducting a randomized, double-blind, placebo-controlled Phase 2b clinical trial of TV-45070 in patients with post-herpetic neuralgia, with topline results expected in mid-2017.

  • Xenon's collaborator Genentech, a member of the Roche Group, has completed two Phase 1 clinical trials for GDC-0276 and GDC-0310, which are both oral, selective Nav1.7 small-molecule inhibitors. Genentech has indicated that it intends to focus its ongoing development efforts on GDC-0310. Pending a full assessment of the Phase 1 clinical results and ongoing in vivo studies, Genentech anticipates initiating a Phase 2 clinical trial in 2017 for the potential treatment of pain.

2016 Financial Results

Cash and cash equivalents and marketable securities as of December 31, 2016 were $64.1 million, compared to $58.7 million as of December 31, 2015. There were 17,930,590 common shares outstanding as of December 31, 2016.

For the year ended December 31, 2016, Xenon reported total revenue of $1.8 million, compared to $15.6 million for the same period in 2015. Revenue in both periods was primarily derived from Xenon's collaboration agreements with Teva and Genentech. The decrease of $13.8 million was primarily attributable to revenue recognized related to the upfront payment from the collaborative development and license agreement with Teva which was fully recognized by December 2015, as well as revenue related to the upfront payment from the March 2014 genetics collaborative agreement with Genentech which was fully recognized by March 2016. The remaining decrease was due to less full time equivalent funding from Genentech as resources were shifted from supporting collaborations to Xenon’s proprietary programs.

Research and development expenses for the year ended December 31, 2016 were $19.8 million, compared to $15.2 million for the same period in 2015. The increase of $4.7 million was primarily attributable to an increase in spending on the XEN901, Nav1.6 sodium channel inhibitor program, as well as XEN801 which entered Phase 2 clinical development in February 2016, partially offset by a decrease in Genentech collaboration expenses.

General and administrative expenses for the year ended December 31, 2016 were $6.8 million, compared to $9.8 million in 2015. During 2015, a $1.7 million expense was recognized due to a fair value adjustment upon the reclassification of stock option awards granted to directors and certain consultants to liability classification. The remaining decrease is due to one-time severance cost resulting from an internal reorganization and acceleration of stock-based compensation expense for certain consultants that occurred in 2015.

Other income for the year ended December 31, 2016 was $1.8 million, compared to other expense of $6.4 million for the same period in 2015. The change of $8.2 million was primarily driven by unrealized foreign exchange gains in 2016 arising from the translation of Canadian denominated balances to U.S. dollars as compared to unrealized foreign exchange losses for the same period in 2015.

Net loss for the year ended December 31, 2016 was $23.0 million, compared to $15.8 million for the same period in 2015. The change was primarily attributable to lower revenue and higher research and development expenses, partially offset by lower general and administrative expenses and the change in unrealized foreign exchange gain (loss).
