The Brilliance Studies program consists of three 12-week, randomized, double-blind, placebo-controlled phase 3 studies evaluating once-daily and split-dose regimens of alixorexton: Brilliance NT1 (Study 302 and Study 304) and Brilliance NT2 (Study 303).
-
Brilliance NT1 Studies (Study 302 and Study 304): Participants in each Brilliance NT1 study will be randomized to receive one of two dosing regimens of alixorexton or placebo to be taken daily for 12 weeks. The primary endpoint of each study will assess whether participants taking alixorexton experience an increase in wakefulness compared to participants taking placebo, as measured by the change in mean sleep latency on the maintenance of wakefulness test (MWT). Secondary endpoints include change in Epworth Sleepiness Scale (ESS) score, mean weekly cataplexy rate (WCR), patient-reported outcomes related to fatigue, cognition and disease severity, and incidence of adverse events. Each study is expected to enroll approximately 150 patients with NT1 across sites in

Brilliance NT2 Study (Study 303): Participants in the Brilliance NT2 study will be randomized to receive one of three dosing regimens of alixorexton or placebo to be taken daily for 12 weeks. The primary endpoint will assess whether participants taking alixorexton experience an increase in wakefulness compared to participants taking placebo alone, as measured by the change in mean sleep latency on the MWT. Secondary endpoints include change in ESS score, patient-reported outcomes related to fatigue, cognition and disease severity, and incidence of adverse events. The Brilliance NT2 study is expected to enroll approximately 180 patients with NT2 across sites in

“The initiation of the phase 3 Brilliance Studies program marks an exciting and important milestone for alixorexton. Building on the positive findings observed in our large phase 2 program across both narcolepsy type 1 and type 2, we are entering this pivotal stage with confidence. We look forward to evaluating alixorexton in both once-daily and split-dose regimens as we seek to optimize efficacy, safety and dosing flexibility in the development of a potential new treatment option for patients and providers,” said
Participants who complete one of the Brilliance Studies will be eligible to continue in a long-term, open-label, safety study. More information can be found at www.brilliancestudies.com (for
About Alixorexton
Alixorexton (formerly referred to as ALKS 2680) is a novel, investigational, oral, selective orexin 2 receptor (OX2R) agonist in development for the treatment of narcolepsy type 1 (NT1), narcolepsy type 2 (NT2) and idiopathic hypersomnia (IH). Orexin, a neuropeptide produced in the lateral hypothalamus, is considered to be the master regulator of wakefulness due to its activation of multiple, downstream wake-promoting pathways that project widely throughout the brain.1 Targeting the orexin system may address excessive daytime sleepiness across hypersomnolence disorders, whether or not deficient orexin signaling is the underlying cause of disease.2 Once-daily oral administration of alixorexton was previously evaluated in a phase 1 study in healthy volunteers and patients with NT1, NT2 and IH, and in Vibrance-1 and Vibrance-2, phase 2 studies in patients with NT1 and NT2, respectively. It is currently being evaluated in the phase 3 Brilliance Studies in patients with NT1 and NT2, and in the phase 2 Vibrance-3 study in patients with IH. Alixorexton has received Breakthrough Therapy designation for the treatment of NT1 from the

Actual performance and results may differ materially from those expressed or implied in the forward-looking statements due to various risks and uncertainties. These risks and uncertainties include, among others: whether initial clinical results for alixorexton will be predictive of results of future stages of ongoing clinical studies, future clinical studies or real-world results; whether ongoing or future clinical studies for alixorexton will be initiated or completed on expected timelines or at all; whether alixorexton could be shown to be ineffective or unsafe; the FDA may not agree with the company’s regulatory strategies or components of its development program for alixorexton, including clinical trial designs, conduct and methodologies; potential changes in the cost, scope and duration of the alixorexton development program; and those risks and uncertainties described under the heading “Risk Factors” in the company’s Annual Report on Form 10-K for the year ended
