Alixorexton Shows Promise in Narcolepsy Treatment, Impacts Fatigue and Cognition
Recent trial results for the drug alixorexton demonstrate meaningful improvements for patients with narcolepsy, extending beyondโ traditional measures of sleepinessโ and cataplexy.Dr. Yountz, discussing the Vibrance-1โข trial, highlighted the drugS positive impact on key symptoms and quality of life factors.
The trial assessed alixorexton across multiple doses and compared it to a placebo. Results showed meaningful improvements in core narcolepsy symptoms, including Maintenance of Wakefulnessโ Test (MWT) scores, Epworth Sleepiness Scale results, and the frequency of cataplexy attacks. Importantly,the drug โฃwas well-tolerated,with โขno unexpected โขsafety signals or trial discontinuations due to โadverseโ events.
Beyond these primary endpoints, exploratory measures โคrevealed notable โฃbenefits in areas frequently reported by patients but often overlooked โin clinical trials: fatigue and cognitive function. Fatigue, described as a pervasive exhaustion distinct from sleepiness, affects over halfโ of individuals โwith narcolepsy. The Vibrance-1 trial utilizedโฃ the PROMIS Fatigue scale and patient Global Impression of fatigue severity, both demonstrating statistically significant and clinically meaningful improvements across allโ dose groups.
Similarly, patients often experience cognitive difficulties, often describedโ as “brain fog,” including issues with focus, memory, and word retrieval. Using the British Columbia Cognitive Complaints โขInventory (BC-CCI)โฃ and direct patient reporting, researchers observed statistically significant and clinically meaningful improvements in cognitive function. The consistency between patient-reported experiences and the structured inventory findings strengthens these results.
These findings suggestโค alixorexton may address the broader disease burdenโ of narcolepsy, impacting not only the ability to stay โawake but also daily functioning, including energy levels, concentration, and overall engagement in life.
Planning is underway for a phase โ3 progress programme,informedโ by the data from Vibrance-1 and a previous โphase 1b study. This program will investigate optimal doses and sensitiveโ endpoints, and will focus on narcolepsyโ type 1 (NT1), narcolepsy type 2 (NT2), andโฃ idiopathic hypersomnia. Further details will be shared as plans are finalized, but the company isโ proceeding โขwith “real momentum” towards potential regulatory approval.
