Xenon Outlines Key Milestones for 2016

January 11, 2016

BURNABY, British Columbia, Jan. 11, 2016 (GLOBE NEWSWIRE) -- Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a clinical-stage biopharmaceutical company, today outlined its anticipated key corporate milestones for 2016.

Dr. Simon Pimstone, Xenon’s President and Chief Executive Officer, stated: “Overall, I am very pleased with the advancements made over the past year within both our proprietary and partnered programs. Our pain-focused collaborations with Teva and Genentech continue to progress well as we work to translate the therapeutic potential of the Nav1.7 target into novel pain therapeutics. In our proprietary programs, we met a major 2015 development milestone by initiating and rapidly completing a Phase 1 trial for XEN801, which is now positioned to enter a Phase 2 clinical trial in patients with moderate to severe acne in the first quarter of 2016, with an expected read-out of results in the second half of 2016.”

Dr. Pimstone added: “We enter 2016 in a strong position with the necessary resources to achieve our near-term goals and to advance a novel and diverse product portfolio. We intend to address large therapeutic markets, such as pain, through partnered programs, and pursue rare or orphan diseases, such as rare forms of childhood epilepsy, by further developing proprietary assets within our own pipeline. Additionally, we expect to continue to leverage our Extreme Genetics technology platform to identify novel targets for drug development.”

Anticipated Advancements of Xenon’s Proprietary Pipeline

  • XEN801, is a topical stearoyl Co-A desaturase, or SCD1 inhibitor, for the treatment of acne. Xenon’s Phase 1 clinical trial for XEN801 was completed in December 2015 with the data supporting the initiation of a Phase 2 clinical trial in the first quarter of 2016. The aim of this Phase 2 trial is to evaluate the efficacy, safety, tolerability and systemic exposure in approximately 150 patients with moderate-to-severe acne. Xenon anticipates receiving topline results in the second half of 2016.
  • Xenon's development of a Nav1.6 sodium channel inhibitor for the treatment of rare childhood epilepsy disorders – such as Dravet Syndrome, an orphan disease of severe childhood epilepsy – continues to progress, and results from early in vivo studies have been encouraging. Xenon expects to identify a development candidate in 2016 and file an investigational new drug (IND) application in the first half of 2017.
  • Xenon will continue 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.

Anticipated Milestones in Partnered Programs

  • 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 trial in 2016.
  • Xenon continues to engage in an active research collaboration with Genentech 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. In September 2015, Xenon announced the successful discovery and identification of a novel pain target, which triggered a milestone payment from 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.

Anticipated Milestones for Commercialized Products

  • Xenon is eligible to receive a royalty on commercial sales of Glybera®, which is licensed to uniQure Biopharma B.V. (Nasdaq:QURE), 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.
