XENE’s Pipeline Updates

Xenon has no approved products in its portfolio at the moment. Therefore, pipeline development remains the key focus of the company.

XENE is currently developing azetukalner in late-stage studies for treatingfocal onset seizures (FOS). Under the phase III epilepsy program, two identical phase III studies, X-TOLE2 and X-TOLE3, are evaluating 15 mg or 25 mg doses of azetukalner, administered with food as adjunctive treatment in patients with FOS. The first top-line data readout from the X-TOLE2 study is anticipated in the second half of 2025.

The company is also evaluating azetukalner for primary generalized tonic-clonic seizures in a phase III X-ACKT study, which is currently enrolling patients and intends to support potential regulatory submissions in this additional epilepsy indication.

Xenon has also completed a phase II proof-of-concept study on azetukalner called X-NOVA for patients with MDD. Based on the success of the mid-stage study, the company initiated the X-NOVA2 study, the first of three planned phase III studies evaluating azetukalner in patients with MDD, during the reported quarter. The X-NOVA3 study is expected to be initiated around mid-2025. 

XENE has also announced plans for a late-stage BPD program, with the first of two azetukalner clinical studies for bipolar I and bipolar II depression. set to begin by mid-year. This decision is driven by a strong scientific foundation, supported by promising clinical data on azetukalner and the Kv7 mechanism in MDD, as well as preclinical research exploring genetic links between BPD and Kv7, along with evidence of Kv7 downregulation in BPD. Additionally, the program aims to address a significant unmet medical need for BPD treatments.

Xenon is also currently collaborating with the Icahn School of Medicine at Mount Sinai to support an ongoing investigator-sponsored phase II proof-of-concept study of azetukalner for the treatment of MDD in approximately 60 subjects. Patient enrollment in the same has been completed and top-line results are anticipated in the first half of 2025.

Furthermore, XENE is currently evaluating multiple preclinical therapeutic candidates targeting Kv7, Nav1.7 and Nav1.1 across various indications, aiming to advance them into clinical development in 2025.
