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

May 9, 2017

BURNABY, British Columbia, May 09, 2017 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a clinical-stage biopharmaceutical company today, reported its financial results for the quarter ended March 31, 2017, and provided a corporate update for 2017.

Dr. Simon Pimstone, Xenon's President and Chief Executive Officer, said, “We continue to leverage our expertise in human genetics and ion channel targets to advance our neurology-focused product candidates and identify potential new therapeutic assets. In addition to our two partnered programs in pain and our proprietary XEN901 epilepsy program, we recently expanded our ion channel, neurology-focused pipeline to include XEN1101, a Kv7 potassium channel opener for the treatment of epilepsy.”

Dr. Pimstone added, “We are positioned to see a number of key events in the coming months including topline data expected mid-year from the Phase 2b clinical trial of TV-45070 in post-herpetic neuralgia being conducted by our collaborator, Teva. We anticipate Genentech will advance GDC-0310 into a Phase 2 clinical trial this year. Within our proprietary programs, we anticipate that XEN1101 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 in the fourth quarter of this year.”

Achievements and Anticipated Milestones

Proprietary Pipeline

  • 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.

  • 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 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.

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. Enrollment is complete with topline results expected in mid-2017.

  • 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 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.

First Quarter 2017 Financial Results

Cash and cash equivalents and marketable securities as of March 31, 2017 were $58.0 million, compared to $64.1 million as of December 31, 2016. There were 17,996,680 common shares outstanding as of March 31, 2017.

For the quarter ended March 31, 2017, Xenon reported total revenue of $0.02 million, compared to $0.6 million for the same period in 2016. The decrease of $0.6 million 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 March 31, 2017 were $5.9 million, compared to $4.4 million for the same period in 2016. The increase of $1.5 million was primarily attributable to increased spending on XEN801 and XEN901 product candidates as well as internal preclinical and discovery programs, partially offset by a decrease in collaboration expenses.

General and administrative expenses for the quarter ended March 31, 2017 were $2.1 million, compared to $1.9 million for the same period in 2016. The increase of $0.2 million was primarily attributable to increased costs for business development and salaries and benefits, partially offset by the fair value adjustment on liability classified stock options.

Other income for the quarter ended March 31, 2017 was $0.5 million, compared to $2.4 million for the same period in 2016. The decrease of $1.9 million was primarily driven by a decrease in unrealized foreign exchange gains arising from the translation of Canadian denominated balances to U.S. dollars.

Net loss for the quarter ended March 31, 2017 was $7.5 million, compared to $3.3 million for the same period in 2016. The change was primarily attributable to lower revenue, higher research and development and general and administrative expenses and lower unrealized foreign exchange gains.
