NEWS RELEASE
Xenon Pharmaceuticals Announces Topline Results from Phase 2 Proof-of-Concept X-NOVA Clinical Trial of XEN1101 in Major Depressive Disorder (MDD)
Conference call today at 8:30 am ET
VANCOUVER, British Columbia, November 27, 2023 – Xenon Pharmaceuticals Inc. (Nasdaq:XENE), a neurology-focused biopharmaceutical company, today reported topline results from the randomized, double-blind, placebo-controlled, Phase 2 proof-of-concept X-NOVA clinical trial, which evaluated the clinical efficacy, safety, and tolerability of 10 mg and 20 mg of XEN1101 in 168 patients with moderate to severe major depressive disorder, or MDD.
Summary of Efficacy Data
Summary of Safety and Tolerability Data
Dr. Christopher Kenney, Xenon’s Chief Medical Officer, stated, “We are encouraged by the data we have generated with XEN1101 in this proof-of-concept study where we see clinically meaningful, dose-dependent drug activity and early onset of efficacy in depression. Importantly, XEN1101 was well tolerated in this patient population, with a low incidence of treatment-emergent adverse events, and no serious adverse events in either dose group. These data also support our belief that XEN1101, through its unique Kv7 mechanism of action, has the potential to play an important role in addressing anhedonia, a common co-morbidity in depression. Overall, there continues to be a strong need for new treatment options for MDD, and we believe XEN1101 has attractive qualities such as a novel mechanism, early onset of action and an overall favorable tolerability and safety profile.”
Ian Mortimer, Xenon’s President and Chief Executive Officer stated, “Based on the totality of data from this study, including clinically meaningful drug activity in depression and anhedonia, we are actively exploring the future development of XEN1101 in MDD and potentially other indications as we believe this mechanism has potential broad applicability.”
Mr. Mortimer continued, “We believe that the data from this study in depression further build upon XEN1101’s compelling product profile in our ongoing Phase 3 development in epilepsy. Data to date support XEN1101’s potential to combine many key features important in treating epilepsy including compelling efficacy in focal onset seizures, rapid efficacy as demonstrated by statistically significant seizure reduction at week 1, a novel mechanism of action with no titration required and other ease of use attributes. We believe the new clinical data we have generated through X-NOVA further support the potential of XEN1101 to have a highly differentiated profile in the treatment of epilepsy given the significant co-morbidity of depression in epilepsy patients. We are excited to share the data generated in X-NOVA with epileptologists and neurologists at the upcoming American Epilepsy Society meeting in December.”
About the Phase 2 X-NOVA Clinical Trial in MDD
The Phase 2 proof-of-concept X-NOVA clinical trial evaluated the clinical efficacy, safety and tolerability of 10 mg or 20 mg of XEN1101 administered as monotherapy with food in patients with MDD. Designed as a randomized, double-blind, placebo-controlled, multicenter clinical study, the primary objective was to assess the efficacy of XEN1101 compared to placebo on improvement of depressive symptoms in subjects diagnosed with moderate to severe MDD, using the MADRS score change through week six. The X-NOVA study included a total of 168 randomized subjects, 167 treated subjects in the safety population, and 164 subjects in the modified intent to treat population for the efficacy analyses. The mean MADRS total scores at baseline were 34.2 for the XEN1101 10 mg group, 33.1 for the XEN1101 20 mg group and 34.5 for the placebo group, representing patients with moderate to severe MDD. Other baseline demographic characteristics were also similar across treatment arms.
