Xenon Pharmaceuticals Reports Third Quarter 2015 Financial Results and Provides Corporate Update

November 10, 2015

Progress Includes Initiation of XEN801 Phase 1 Clinical Trial and Achievement of Milestones in Genentech Nav1.7 Clinical Program and Pain Genetics Collaboration

Conference Call/Webcast Today at 5:00 p.m. Eastern Time

BURNABY, British Columbia, Nov. 10, 2015 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a clinical-stage biopharmaceutical company, today reported its financial results for the quarter ended September 30, 2015 and provided a corporate update.

Dr. Simon Pimstone, Xenon's President and Chief Executive Officer, said, "We are pleased with our progress in the third quarter in advancing both our partnered and proprietary programs. We have achieved important milestones that underscore the therapeutic potential and breadth of our pipeline and the value of our Extreme Genetics platform. We have achieved two recent milestones in our collaboration with Genentech including advancement of a second Nav1.7 inhibitor into clinical testing and identification of a novel pain gene in our pain genetics collaboration. In addition, we advanced XEN801 into clinical development and a Phase 1 trial is ongoing. We believe that we are well positioned to continue to build on this momentum, with additional development stage milestones anticipated for the remainder of this year and into 2016, and that we have sufficient resources and capabilities to achieve our near-term goals."

2015 Achievements to Date

Partnered Pain Programs with Teva and Genentech

  • Xenon's partner Teva Pharmaceutical Industries Ltd. is conducting a randomized, double-blind, placebo-controlled Phase 2b clinical trial for TV-45070 in patients with post-herpetic neuralgia, with results expected in the second half of 2016.
  • Xenon's partner Genentech Inc., a member of the Roche Group, is currently conducting a Phase 1 clinical trial for GDC-0276, which is expected to complete patient enrollment by the end of 2015. GDC-0276 is a selective, oral Nav1.7 small-molecule inhibitor being developed for the treatment of pain.
  • Genentech recently advanced a second selective, oral Nav1.7 small-molecule inhibitor, GDC-0310, into a Phase 1 clinical trial.
  • Xenon and Genentech also have an active research collaboration focused on other selective, oral small molecule inhibitors of Nav1.7.
  • Xenon and Genentech's second collaboration is focused on the discovery of novel pain targets in rare human pain disorders where individuals have either an inability to perceive pain or where individuals have non-precipitated spontaneous severe pain. Xenon met a key goal of this collaboration by identifying a new pain target, triggering a milestone payment in September 2015.

Xenon's Proprietary Programs

  • XEN801, is a stearoyl Co-A desaturase, or SCD1 inhibitor, for the treatment of acne. Xenon initiated a Phase 1 clinical trial for XEN801 in September 2015. If supported by positive data from the Phase 1 trial, Xenon plans to initiate a Phase 2 clinical trial by the end of 2015 or early 2016 in patients with moderate to severe acne. SCD1 is an enzyme involved in lipid synthesis that is expressed in sebaceous glands in the skin. By inhibiting SCD1, XEN801 represents a novel approach to treat acne with a dual mechanism of action expected to reduce both sebum production and the size and number of sebaceous glands.
  • Xenon's development of a Nav1.6 sodium channel inhibitor for the treatment of Dravet Syndrome, an orphan disease of severe childhood epilepsy, continues to progress and Xenon expects to file an investigational new drug application in the second half of 2016. Xenon's approach to treating Dravet Syndrome is to develop selective and potent inhibitors of Nav1.6 which have demonstrated efficacy for seizures in a pre-clinical animal model.
  • Xenon also anticipates announcing its next drug discovery program in 2015 by leveraging its Extreme Genetics discovery platform and expertise in ion channel chemistry and biology.


  • Xenon's Glybera licensee, uniQure Biopharma B.V. (Nasdaq:QURE), has reported that its commercialization partner, Chiesi Farmaceutici S.p.A., has submitted price and reimbursement dossiers in key European countries in order to make Glybera accessible to patients. Chiesi has sole control over commercialization in Europe and neither uniQure nor Xenon will be providing additional guidance regarding commercialization progress. Glybera is the first gene therapy product approved in the European Union for the treatment of the orphan disorder lipoprotein lipase deficiency, and is the first product whose active ingredient was derived from Xenon's platform to receive commercial approval. Xenon is eligible to receive a royalty on commercial sales.

Third Quarter 2015 Financial Results

Cash and cash equivalents and marketable securities as of September 30, 2015 were $65.5 million, compared to $84.0 million as of December 31, 2014. There were 14,344,267 shares outstanding as of September 30, 2015.

For the quarter ended September 30, 2015, Xenon reported total revenue of $4.3 million, compared to $13.2 million for the same period in 2014. Revenue in both periods was primarily derived from Xenon's collaboration agreements with Teva and Genentech. The decrease of $8.9 million was primarily attributable to an $8.0 million milestone payment from Genentech in the third quarter of 2014 and revenue recognized relating to the upfront payment from the December 2011 collaborative development and license agreement with Genentech which was fully recognized by December 2014. The remaining decrease was due to less full time equivalent funding from Genentech and Teva and the change in the foreign exchange rate between the U.S. and Canadian dollar.

Research and development expenses for the quarter ended September 30, 2015 were $3.8 million, compared to $3.2 million for the same period in 2014. The increase of $0.6 million was primarily attributable to an increase in spending on XEN801 in preparation for clinical development which began in September 2015 and the Nav1.6 sodium channel inhibitor program, partially offset by decreases in Teva and Genentech collaboration expenses.

General and administrative expenses for both the quarter ended September 30, 2015 and the same period in 2014 were $1.3 million. For the three months ended September 30, 2015, we recognized a recovery of $1.0 million due to the change in fair value of our liability classified stock options granted to directors and certain consultants until the options were reclassified back to equity in September 2015. Offsetting the recovery was an increase primarily attributable to additional expenses incurred as a public company and acceleration of stock based compensation expense for certain consultants.

Other expense for the quarter ended September 30, 2015 was $3.0 million, compared to other income of $0.5 million for the same period in 2014. The change of $3.5 million was primarily attributable to $3.1 million of unrealized foreign exchange losses arising from the translation of Canadian denominated balances to U.S. dollars as a result of the functional currency change to U.S. dollars from Canadian dollars on January 1, 2015.

Net loss for the quarter ended September 30, 2015 was $3.8 million, compared to net income of $9.2 million for the comparative period in 2014. The decrease was primarily attributable to lower revenue, higher operating expenses and unrealized foreign exchange losses recorded in the quarter ended September 30, 2015.
