Xenon has a number of promising therapeutics in clinical development, valuable collaborations with pharmaceutical partners, and innovative early-stage research underway and also has a strong balance sheet to support its continued growth in 2021 and beyond.

We are a collaborative, ambitious, and driven team with a common mission to improve the lives of patients with neurological disorders. Creating a healthy and productive work environment is a priority, and we understand the importance of investing in our employees’ growth and development.
