Xenon Pharmaceuticals (XENE) submitted a New Drug Application for azetukalner in treating focal seizures, while pausing new enrollments in depression studies due to adverse events. The epilepsy program is supported by positive Phase 2b and 3 trial results, with seizure frequency reductions of 53.2% and 34.5% for 25 mg and 15 mg doses, respectively. The psychiatric program's future depends on addressing tolerability issues and upcoming trial results in 2027.
