Company Presents Additional Positive Data from Open Label Extension of Phase 2b ‘X-TOLE’ Clinical Trial for Focal Onset Seizures
XEN1101 Phase 3 Program to be Showcased at Scientific Exhibit Taking Place on Sunday, December 4, 2022
BURNABY, British Columbia, Dec. 02, 2022 (GLOBE NEWSWIRE) — Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a neurology-focused biopharmaceutical company, today announced it will provide updates on its proprietary, neurology programs at the Annual Meeting of the American Epilepsy Society (AES 2022). In addition, the Company is presenting results from the open label extension (OLE) and sub-analyses of data from the XEN1101 Phase 2b X-TOLE clinical trial.
Mr. Ian Mortimer, Xenon’s President and Chief Executive Officer stated, “We continue to advance our portfolio of neurology-focused programs. Xenon will have a significant presence at AES this year with seven poster presentations and a scientific exhibit showcasing our recently launched XEN1101 Phase 3 program and our planned clinical trials in focal onset seizures and primary generalized tonic clonic seizures. We also look forward to meeting with leading epileptologists, including Xenon trial investigators, as well as patient advocacy groups at this important meeting.”
Mr. Mortimer continued, “Importantly, we have a scientific poster outlining additional data from the open-label extension of the XEN1101 Phase 2b X-TOLE study. This interim analysis shows XEN1101 continues to be generally well-tolerated, yielding long-term efficacy at the 20 mg once-daily dose, with patients experiencing continued seizure reduction during the OLE and extended periods of seizure freedom. Two other XEN1101-related posters outline additional sub-analyses of the X-TOLE data that suggest a rapid onset of efficacy of XEN1101, with statistically significant reduction in focal onset seizures within one week for all doses studied when compared to placebo. Further, based on the number of concomitant ASMs, baseline seizure frequency, and number of failed anti-seizure medications, the X-TOLE study enrolled more ‘difficult-to-treat’ patients than other similar focal onset seizure studies. We believe this is important as it suggests that the efficacy of XEN1101 may be robust in patients with less severe disease, which may represent the most common use of XEN1101 if commercially approved. With these promising data, we have now initiated our XEN1101 Phase 3 program, where we hope to confirm these encouraging results and continue to execute on our goal to deliver a new, differentiated therapeutic that could potentially play a key role in treating patients with epilepsy.”
