NUTLEY, N.J., July 8, 2024 /PRNewswire/ -- Eisai Inc. announced today that screening for Study E2086-A001-101 (Study 101) to assess the efficacy, safety and tolerability of E2086, a novel selective orexin-2 receptor, is now registered on ClinicalTrials.gov as NCT06462404. Study sites are also planned for Canada.

Study 101 is a five-period, single-dose crossover study in adult patients with narcolepsy type 1 (NT1). Three dose strengths of E2086 will be assessed compared with placebo and an active comparator using objective and patient-reported measures of wake promotion.

Narcolepsy is a sleep disorder resulting from disorganization of the sleep/wakefulness cycle. In patients with NT1, excessive daytime sleepiness and cataplexy (acute episodes of loss of muscle tone) are reported in association with low levels of the neurotransmitter orexin. As a selective orexin-2 receptor agonist, E2086 is hypothesized to compensate for the loss of orexin in patients with NT1. In nonclinical studies, E2086 was shown to increase wake time and decrease cataplexy-like episodes in narcolepsy model mice.¹

"The availability of drugs like E2086 will open a new era in the treatment of narcolepsy and potentially other disorders of hypersomnolence," said Lynn Kramer, MD, FAAN, Chief Clinical Officer, Deep Human Biology Learning (DHBL), Eisai. "By addressing the deficiency of orexin with what is in essence a replacement therapy, E2086 will hopefully provide a meaningful impact on the symptoms and the consequences associated with narcolepsy to improve the quality of lives of these patients."
