Joseph Thome's questions to Xenon Pharmaceuticals Inc (XENE) leadership • Q2 2025
Question
Joseph Thome of TD Cowen asked about the company's confidence in derisking liver toxicity for its Kv7 pain program, whether any quality-of-life measures for Ezetucalner have captured pain-related data, and what level of detail, such as seizure freedom rates, to expect in the top-line data release.
Answer
President and CEO Ian Mortimer stated that the liver toxicity of a prior drug (flupertine) was likely not on-target and that Xenon has no current concerns with its candidate, XEN1101. He also confirmed the top-line release will be detailed, consistent with past disclosures. Chief Medical Officer Christopher Kenney noted that while they have strong QoL data, specific pain data is limited to migraine headache capture in the epilepsy trials, which did not enrich for that comorbidity.
