Xenon Pharmaceuticals Reports Second Quarter 2017 Financial Results and Provides Corporate Update

August 3, 2017

BURNABY, British Columbia, Aug. 03, 2017 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a clinical-stage biopharmaceutical company, today reported its financial results for the quarter ended June 30, 2017, and provided a corporate update for 2017.

Dr. Simon Pimstone, Xenon's President and Chief Executive Officer, said, “We remain focused on our strategy to develop ion channel modulators, backed by strong human genetic validation, for neurological disorders. Both of our proprietary programs, XEN1101 and XEN901, are highly differentiated molecules being developed as anti-epileptic drugs. We have also partnered with collaborators at Genentech to advance a novel, selective oral Nav1.7 inhibitor for the treatment of pain.”

Dr. Pimstone added, “With a healthy balance sheet, we are positioned to fully support these key clinical programs and look forward to a number of important events in the coming months. We anticipate that XEN1101, a Kv7 potassium channel opener, will be in a Phase 1 clinical trial in the fourth quarter of 2017. In addition, we look forward to filing an IND, or IND equivalent, application for XEN901, a selective Nav1.6 inhibitor, in the fourth quarter of this year. We also anticipate Genentech will advance GDC-0310 into a Phase 2 clinical trial in the first quarter of 2018.”

Second Quarter 2017 Highlights and Anticipated Milestones

  • XEN1101 is a next-generation Kv7 potassium channel opener for the treatment of epilepsy. Pre-clinically, XEN1101 has demonstrated improved pharmacokinetics, selectivity, potency and efficacy over first-generation potassium channel modulators, such as ezogabine. Xenon anticipates filing an investigational new drug (IND), or IND equivalent, application to initiate a Phase 1 first-in-man clinical trial in the fourth quarter of 2017, and Phase 2 development is anticipated to begin by mid-2018.
  • XEN901 is a potent, selective Nav1.6 sodium channel 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 animal models that support the treatment of adult partial onset epilepsy. Xenon expects to file an IND, or IND equivalent, application in the fourth quarter of 2017.
  • TV-45070 is a topical, small-molecule inhibitor of the sodium channel Nav1.7, and other sodium channels, expressed in the pain-sensing peripheral nervous system. In June 2017, Xenon, along with its collaborator, Teva Pharmaceutical Industries Ltd., announced topline results from a Phase 2b clinical trial that evaluated the efficacy and safety of TV-45070 in patients with post-herpetic neuralgia. TV-45070 did not meet the primary endpoint of a statistically significant change in pain from baseline to week four as assessed by the numeric rating scale (NRS), and secondary endpoints were also not met. There were no safety concerns in the study. The companies plan to further analyze the data from this study to determine the next steps for TV-45070.
  • Xenon's collaborator Genentech, a member of the Roche Group, has completed a Phase 1 clinical trial for GDC-0310, which is an oral, selective Nav1.7 small-molecule inhibitor. Pending completion and assessment of ongoing preclinical studies, Genentech anticipates initiating a Phase 2 clinical trial for the potential treatment of pain in the first quarter of 2018.
  • In July 2017, Xenon achieved a milestone in its pain genetics discovery collaboration with Genentech triggering a milestone payment. Xenon and Genentech have successfully discovered and identified a novel pain target by leveraging Xenon's Extreme Genetics platform based on the study of rare phenotypes of individuals who have either an inability to perceive pain or have non-precipitated spontaneous severe pain.

Second Quarter 2017 Financial Results

Cash and cash equivalents and marketable securities as of June 30, 2017 were $51.7 million, compared to $64.1 million as of December 31, 2016. There were 17,998,420 common shares outstanding as of June 30, 2017. Based on current assumptions, which include fully supporting the planned clinical development of XEN1101 and XEN901, Xenon anticipates having sufficient cash to fund operations into the first quarter of 2019, excluding any revenue generated from existing partnerships or potential new partnering arrangements.

For the quarter ended June 30, 2017, Xenon reported total revenue of $0.02 million, compared to $0.4 million for the same period in 2016. The decrease was primarily attributable to revenue recognized 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 collaborative partners as resources were shifted from supporting collaborations to Xenon’s proprietary programs.

Research and development expenses for the quarter ended June 30, 2017 were $6.1 million, compared to $5.1 million for the same period in 2016. The increase of $1.0 million was primarily attributable to increased spending on internal preclinical and discovery programs, including XEN901 and XEN1101 which was acquired in April 2017, partially offset by a decrease in XEN801 expenses, a product candidate which is no longer being developed, and a decrease in collaboration expenses.

General and administrative expenses for the quarter ended June 30, 2017 were $1.8 million, compared to $1.7 million for the same period in 2016. The increase of $0.1 million was primarily attributable to increased costs for business development activities and salaries and benefits, partially offset by the fair value adjustment on liability classified stock options.

Other income for the quarter ended June 30, 2017 was $0.5 million, compared to $0.4 million for the same period in 2016. The increase was primarily driven by an increase in unrealized foreign exchange gains arising from the translation of Canadian denominated balances to U.S. dollars.

Net loss for the quarter ended June 30, 2017 was $7.4 million, compared to $6.0 million for the same period in 2016. The change was primarily attributable to lower revenue, higher research and development and general and administrative expenses, partially offset by higher unrealized foreign exchange gains.
