XEN007 (active ingredient flunarizine) is a CNS-acting calcium channel inhibitor, which is available in certain countries outside of
The XEN1101 Phase 2b clinical trial 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 adult patients with focal epilepsy. Approximately 300 patients will be randomized in a blinded manner to one of three active treatment groups or placebo in a 2:1:1:2 fashion (XEN1101 25 mg : 20 mg : 10 mg : Placebo). The primary endpoint is the median percent change in monthly focal seizure frequency from baseline compared to treatment period of active versus placebo. Depending upon the rate of enrollment, top-line results from the XEN1101 Phase 2b clinical trial are anticipated in the second half of 2020.
About Alternating Hemiplegia of Childhood (AHC)
AHC is a devastating and life-threatening neurological disease associated with significant morbidity that has substantial impact on day-to-day functioning. AHC presentation includes repeated attacks of hemiplegia involving either side of the body or episodes of quadriplegia, paroxysmal disturbances including tonic or dystonic spells, and developmental deterioration and neurologic abnormalities, which all initially present before 18 months of age. Oculomotor features have been documented to occur within one or two days after birth, with onset of hemiplegia and dystonia occurring as early as one month after birth. AHC children suffer from debilitating painful paroxysmal events that can last for days or weeks and fixed non-paroxysmal symptoms. A recent study conducted nationwide in
