Xenon Pharmaceuticals Reports Second Quarter 2019 Financial Results and Provides Corporate Update
Anticipate Testing of New Pediatric Formulations of XEN496 and XEN901 in Adults in Third Quarter,
Followed by IND Submissions to Initiate Pediatric Clinical Trials in
KCNQ2 and SCN8A Developmental and Epileptic Encephalopathies
Conference Call at
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 developmental and epileptic encephalopathy (KCNQ2-DEE). Xenon has developed XEN496 as a pediatric-specific, granule formulation to be packaged as single-dose sachets, and plans to test XEN496 in healthy adult volunteers in a pharmacokinetic (PK) study that we expect to initiate in the third quarter of 2019. Xenon expects to file an Investigational New Drug (IND) application in the fourth quarter of 2019 in order to initiate a Phase 3 clinical trial in KCNQ2-DEE. The FDAhas indicated that it is acceptable to study XEN496 in infants and children up to 4 years old, and that a single, small pivotal trial may be considered adequate in order to demonstrate XEN496’s efficacy in KCNQ2-DEE, provided the study shows evidence of a clinically meaningful benefit in patients with the intended indication.
- 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 for this XEN1101 Phase 2b clinical trial are currently underway in
the United States, Canadaand Europe. Long term 6-and 9-month toxicology studies are underway and are expected to support the planned 12-month open label extension for patients enrolled in the Phase 2b clinical trial. Depending upon the rate of enrollment, top-line results 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. A XEN901 Phase 1 clinical trial has been completed. Xenon received important feedback from the
FDAregarding the requirements for clinical development of our XEN901 program, including feedback to support advancing XEN901 directly into a pediatric clinical trial examining its efficacy in pediatric patients with SCN8A epileptic encephalopathy (SCN8A-EE). Xenon has recently completed the development of a pediatric-specific granule formulation of XEN901 and is in the process of completing juvenile toxicology studies to support pediatric development activities. Xenon intends to run a PK study in healthy adult volunteers with the new XEN901 pediatric formulation beginning in the third quarter of this year, followed by an IND submission to start a proposed Phase 2 or 3 clinical trial in SCN8A-EE patients.
- 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 (CAE). 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, and various development strategies for XEN007 are under consideration. In the near term, Xenon anticipates the initiation of a physician-led Phase 2 open label study examining the potential clinical efficacy, safety, and tolerability of XEN007 as an adjunctive treatment of CAE.
Second Quarter 2019 Financial Results
