Achievements and Anticipated Milestones
- XEN496 (active ingredient ezogabine) is a Kv7 potassium channel modulator being developed by Xenon. The
FDAhas granted orphan drug designation (ODD) for XEN496 as a treatment of KCNQ2 epileptic encephalopathy (KCNQ2-EE). Xenon is currently finalizing a pediatric-specific formulation to complete pre-clinical formulation testing with a final drug product expected in the second quarter of 2019. Xenon is planning to test the XEN496 pediatric formulation in a study of healthy adult volunteers, which is expected to be initiated in the third quarter of 2019. Xenon expects to file an Investigational New Drug (IND) application in the fourth quarter of 2019 to initiate a Phase 3 clinical trial in KCNQ2-EE. The FDAhas indicated that it is acceptable to study XEN496 in infants and children up to 4 years old, and that a single pivotal trial in approximately 20 patients may be considered adequate in order to demonstrate XEN496’s efficacy in KCNQ2-EE.
- XEN1101 is a differentiated Kv7 potassium channel modulator being developed for the treatment of epilepsy and potentially other neurological disorders. Xenon has initiated a Phase 2b clinical trial, which is designed as a randomized, double-blind, placebo-controlled, multicenter study to evaluate the clinical efficacy, safety and tolerability of XEN1101 administered as adjunctive treatment in approximately 300 adult patients with focal epilepsy. The primary endpoint is the median percent change in monthly focal seizure frequency from baseline compared to treatment period of active versus placebo. Site selection and patient enrollment are now underway for the XEN1101 Phase 2b clinical trial in
the United States, Canadaand Europe. Depending upon the rate of enrollment, top-line results from the XEN1101 Phase 2b clinical trial are anticipated in the second half of 2020.
- XEN901 is a potent, highly selective Nav1.6 sodium channel inhibitor being developed for the treatment of epilepsy. Results from a XEN901 Phase 1 clinical trial and related pilot TMS study were announced in
December 2018. The next steps for XEN901 include continued planning for Phase 2 or later clinical development to evaluate XEN901 as a treatment for rare, pediatric forms of epilepsy, including SCN8A epileptic encephalopathy (SCN8A-EE) or adult focal seizures, depending on feedback from regulatory agencies. Xenon expects to receive feedback on the requirements to advance XEN901 into pediatric SCN8A-EE patients in the second quarter of 2019. In order to support future pediatric development plans, juvenile toxicology studies and pediatric formulation work are underway.
- XEN007 (active ingredient flunarizine) is a CNS-acting calcium channel modulator that modulates Cav2.1 and T-type calcium channels. Other reported mechanisms include dopamine, histamine and serotonin inhibition. Available in certain countries outside of
the United States, flunarizine has been reported to have clinical benefit in treating migraine and other neurological disorders, including hemiplegic migraine (HM), alternating hemiplegia of childhood (AHC), vertigo, and as an adjunctive treatment in certain epilepsies, including childhood absence epilepsy. The FDAgranted a rare pediatric disease designation for the treatment of AHC with XEN007, and previously granted ODD for XEN007 as a treatment of both AHC and HM. To support the advanced clinical development of XEN007, Xenon has entered into key licensing and manufacturing agreements. Various development strategies for XEN007 are under consideration, including the support of at least one Phase 2 (or later stage) clinical trial in an orphan neurological indication, with initiation anticipated in 2019.
