- Clinical Trial Success: Xenon's X-TOLE2 study demonstrated that azetukalner achieved its primary endpoint in treating focal onset seizures, with a placebo-adjusted MPC of -42.7% in the 25 mg group, significantly outperforming the previous Phase 2b study's -34.6%, indicating a potential shift in epilepsy treatment paradigms.
