Xenon Pharmaceuticals reports Q3 2026 loss, submits NDA for azetukalner and outlines pipeline milestones

Xenon Pharmaceuticals announced third‑quarter 2026 results showing a net loss of $110.4 million, or $1.11 per share, widening 21% from a year earlier. Revenue missed forecasts and R&D expenses rose to $95.6 million. The company submitted a New Drug Application to the FDA for azetukalner in focal seizures, completed enrollment in its Phase 3 X‑NOVA2 depression study, and expects topline data in December 2026. It also reported a cash balance of about $1.15 billion, which management says will fund operations into 2029.

The widened loss and revenue miss pressured the stock, which fell 2.4% in after‑hours trading (the company’s stock impact). However, the NDA submission and strong cash runway give the company the financial flexibility to continue advancing its epilepsy, neuropsychiatry and pain programs through 2029, according to management.
