XENE's Q1 Results in Detail
In the first quarter, research and development (R&D) expenses increased 38.1% year over year to $61.2 million. The uptick was primarily due to increased expenses related to the company’s azetukalner late-stage epilepsy studies and initiation of the first phase III major depressive disorder (MDD) for the same candidate.
General and administrative expenses were $19 million in the reported quarter, up 28.4% year over year, owing to increased personnel-related costs due to higher employee headcount.
Xenon had cash, cash equivalents and marketable securities worth $691.1 million as of March 31, 2025, compared with $754.4 million as of Dec. 31, 2024. The company expects its existing cash balance to fund its current operating plans, which include the completion of the azetukalner phase III epilepsy studies and fully support late-stage clinical development of azetukalner in MDD and bipolar depression (BPD) into 2027.
XENE's Pipeline Updates
XENE’s lead pipeline candidate, azetukalner, is in late-stage studies for treating focal 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 now anticipated in early 2026, which was earlier expected 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.
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 recently initiated the X-NOVA2 study, the first of three planned phase III studies on azetukalner in MDD. The second MDD study, X-NOVA3, is expected to be initiated in mid-2025.
Earlier this year, Xenon announced plans for a late-stage BPD program, with the first of the two azetukalner clinical studies for bipolar I and bipolar II depression set to begin by mid-year. The program aims to address a significant unmet medical need for BPD treatments.
Xenon is currently evaluating multiple preclinical therapeutic candidates targeting Kv7, Nav1.7 and Nav1.1 across various indications, aiming to advance them into clinical development later in 2025.
The company expects to file an investigational new drug application and initiate a phase I study on its lead Nav1.7 candidate, XEN1701, in the third quarter of 2025. Per management, Nav1.7 is an important pain-related target that may be a new class of medicines without the limitations of opioids.
