Xenon Pharmaceuticals Reports Second Quarter 2016 Financial Results and Provides Corporate Update

August 3, 2016

BURNABY, British Columbia, Aug. 03, 2016 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a clinical-stage biopharmaceutical company, today reported its financial results for the quarter ended June 30, 2016 and provided a corporate update.

Dr. Simon Pimstone, Xenon's President and Chief Executive Officer, said, “Our proprietary programs continue to advance as we make strong progress towards our corporate milestones. We have now surpassed 50% enrollment in our XEN801 Phase 2 clinical trial in patients with moderate to severe acne, and based on updated projections, we anticipate a read out of top-line results in the first quarter of 2017. Within our preclinical Nav1.6 program, we are working with numerous potent, selective Nav1.6 inhibitors that have demonstrated efficacy for seizures in preclinical models, supporting the hypothesis that inhibiting the Nav1.6 channel could play a key role in treating rare and severe forms of childhood epilepsy. We expect to file an investigational new drug (IND) application in the first half of 2017.”

Dr. Pimstone added, “Our pain-focused collaborations with Teva and Genentech also continue to progress well as we work to translate the therapeutic potential of the Nav1.7 target into novel pain therapeutics. These partnerships allow us to address large market opportunities, while at the same time enable us to pursue multiple therapeutic opportunities to build out our proprietary pipeline of novel therapies that address rare or orphan indications.”

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. We have currently enrolled approximately half of the patients in our ongoing 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. Xenon expects to enroll approximately 150 patients with moderate to severe acne, with topline results expected in the first quarter of 2017.

    Xenon presented data from the XEN801 Phase 1 clinical trial where 48 healthy volunteers were dosed for either a 14-day or 21-day treatment period. A number of different dose volumes of the 1% XEN801 drug product were evaluated in the Phase 1 clinical trial with dosing on the back and face of healthy volunteers to determine the maximum tolerated dose. As expected, the most common side effects were localized, generally mild skin reactions. No serious adverse events were observed. Maximal plasma concentrations of XEN801 were low, whereas skin biopsies from the back of subjects showed a concentration of approximately two orders of magnitude higher than the IC50 and higher than that required for 100% block of SCD1. It is expected that XEN801 could achieve even better penetration in the facial skin, as currently applied in the current Phase 2 clinical trial. A Phase 2 dose was selected based on favorable tolerability and skin drug concentrations.
  • Xenon's development of a Nav1.6 sodium channel inhibitor for the treatment of rare infantile epileptic encephalopathies – such as Dravet Syndrome and SCN8A (Nav1.6 gain-of-function) Epilepsy – continues to progress well. Xenon has identified potent, selective Nav1.6 inhibitors, and encouraging results from in vivo animal studies indicate that selective Nav1.6 inhibitors have demonstrated efficacy for seizures in a model of Nav1.6 gain-of-function SCN8A epilepsy, supporting the hypothesis that SCN8A epilepsies can be treated with potent, selective Nav1.6 inhibitors. Xenon expects to identify a development candidate in 2016 and file an investigational new drug (IND) application in the first half of 2017.
  • Xenon continues to leverage its drug discovery platform to identify validated drug targets and develop new product candidates, and expects to provide updates as new drug discovery programs advance in 2016.

Partnered Programs

  • TV-45070 is a product candidate being developed in collaboration with Xenon’s partner, Teva Pharmaceutical Industries Ltd., for the treatment of pain. Teva is currently 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 first half of 2017.
  • Xenon's partner Genentech, a member of the Roche Group, is currently conducting two Phase 1 clinical trials for GDC-0276 and GDC-0310, which are both oral, selective Nav1.7 small-molecule inhibitors being developed for the potential treatment of pain. Both Phase 1 clinical trials are ongoing, and pending a full assessment of the results, Genentech intends to initiate a Phase 2 clinical trial in late 2016 or early 2017. The research term for Xenon’s second collaboration with Genentech, which is centered on pain genetics, was recently extended for another year until March 2017.
  • Xenon is eligible to receive a royalty on commercial sales of Glybera, which is licensed to uniQure Biopharma B.V. for the treatment of the orphan disorder lipoprotein lipase deficiency. The first patient treated with Glybera as a commercially-available gene therapy was announced by uniQure in November 2015 and enabled by its commercialization partner in the EU, Chiesi Farmaceutici S.p.A.

Second Quarter 2016 Financial Results

Cash and cash equivalents and marketable securities as of June 30, 2016 were $50.7 million, compared to $58.7 million as of December 31, 2015. There were 14,415,347 common shares outstanding as of June 30, 2016.

For the quarter ended June 30, 2016, Xenon reported total revenue of $0.4 million, compared to $4.0 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 $3.6 million was primarily attributable to revenue recognized relating 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 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 we shifted resources from supporting our collaborations to our proprietary programs.

Research and development expenses for the quarter ended June 30, 2016 were $5.1 million, compared to $3.7 million for the same period in 2015. The increase of $1.4 million was primarily attributable to an increase in spending on our 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 quarter ended June 30, 2016 were $1.7 million, compared to $0.2 million in 2015. In the quarter ended June 30, 2015, a $2.2 million recovery was recognized due to a decrease in the fair value of liability classified stock options granted to directors and certain consultants; these options were subsequently reclassified back to equity in September 2015. The remaining change is due to one-time severance costs resulting from an internal reorganization and acceleration of stock based compensation expense for certain consultants that occurred in the second quarter of 2015.

Other income for the quarter ended June 30, 2016 was $0.4 million, compared to $1.0 million for the same period in 2015. The decrease of $0.6 million was primarily attributable to a decrease in unrealized foreign exchange gains arising from the translation of Canadian denominated balances to U.S. dollars as compared to the same period in 2015.

Net loss for the quarter ended June 30, 2016 was $6.0 million, compared to net income of $1.2 million for the same period in 2015. The change was primarily attributable to lower revenues, higher general and administrative expenses largely due to stock based compensation recovery, higher research and development expenses and lower unrealized foreign exchange gains.
