Associate Director, Scientific Communications

Who We Are:

Xenon Pharmaceuticals (NASDAQ:XENE) is a neuroscience-focused biopharmaceutical company dedicated to drug discovery, clinical development, and commercialization of life-changing therapeutics for patients in need. We are looking for great people who thrive in a respectful, collaborative, inclusive, and productive culture to join the Xenon team.

What We Do:

We are advancing an exciting product pipeline to address indications with high unmet medical need, including epilepsy and depression. Our Phase 3 azetukalner program represents the most advanced, clinically validated potassium channel modulator in late-stage clinical development for multiple indications. Building upon the positive results and compelling data from our Phase 2b X-TOLE study in adult patients with focal epilepsy, our Phase 3 epilepsy program includes multiple clinical trials evaluating azetukalner in patients with focal onset seizures and primary generalized tonic-clonic seizures. In November 2025, we announced the completion of patient enrollment in our Phase 3 X-TOLE2 study, and topline data are anticipated in March 2026. We also have multiple Phase 3 azetukalner clinical trials in major depressive disorder (MDD) and bipolar depression (BPD) underway, based on topline data from our Phase 2 X-NOVA clinical trial. In addition, we are proud of the leading-edge science coming out of our discovery labs, including early-stage research programs that leverage our extensive ion channel expertise and drug discovery capabilities to identify validated drug targets and develop new product candidates. We have recently initiated Phase 1 studies for our follow-on Kv7 channel opener, XEN1120, and our lead Nav1.7 development candidate, XEN1701, in pain. Backed by a strong balance sheet to support our growth plans, we continue to build a fully integrated, premier neuroscience company with strong discovery, clinical development, corporate, and commercial operations.
