Study to Evaluate the Respiratory Safety of Lemborexant in Adult and Elderly Healthy Subjects and Adult and Elderly Subjects With Mild Obstructive Sleep Apnea
Study Details
Study Description
Brief Summary
This study will be conducted to determine whether lemborexant as compared to placebo decreases the peripheral oxygen saturation during total sleep time in healthy adult and elderly participants after a single dose of treatment and to determine whether it increases the apnea-hypopnea index after single and multiple doses of treatment in adult and elderly participants with mild obstructive sleep apnea (OSA).

Detailed Description
Healthy Volunteer (HV) Cohort:
The HV Cohort comprises a randomized, double-blind, placebo-controlled, 3-period crossover study. Eligible healthy adult and elderly participants will be randomized to treatment sequence A, B, or C, each consisting of 3 Treatment Periods, each of one night's duration, in which participants will receive a single dose of lemborexant 10 milligrams (mg), or lemborexant 25 mg, or placebo. Treatment Periods will be separated by a washout interval of at least 14 days. A sufficient number of participants will be randomized to ensure that 8 evaluable adult participants (<65 years) and 4 evaluable elderly participants (≥65 years) complete the study.
OSA Cohort:
The OSA Cohort comprises a multiple-dose, randomized, double-blind, placebo-controlled, 2-period crossover study. Adult and elderly participants with mild OSA will be randomized to treatment sequence D or E, each consisting of 2 Treatment Periods, each of 8 nights' duration, in which participants will receive lemborexant 10 mg or placebo. The Treatment Periods will be separated by a washout interval of at least 14 days. A sufficient number of participants will be randomized to ensure that 20 evaluable adult participants (<65 years) and 10 evaluable elderly participants (≥65 years) complete the study.

Outcome Measures
Primary Outcome Measures
- HV Cohort: Peripheral Oxygen Saturation (SpO2) During Total Sleep Time (TST) on Day 1 of Treatment [Day 1]
SpO2 is an estimate of the amount of oxygen in the blood. It is the percentage of hemoglobin containing oxygen compared to the total amount of hemoglobin in the blood (that is, oxygenated hemoglobin versus oxygenated and non-oxygenated hemoglobin). SpO2 was monitored by noninvasive method known as transmissive pulse oximetry. TST was defined as the total time asleep in minutes using polysomnography (PSG).
- OSA Cohort: Apnea-Hypopnea Index (AHI) on Day 8 of Treatment [Day 8]
The AHI is the number of apneas and hypopneas per hour of sleep. AHI less than 5 is considered normal. An AHI from 5 to 14 denotes mild sleep apnea, 15 to 30 is moderate, while a greater than 30 AHI is considered severe.
Secondary Outcome Measures
- HV Cohort: AHI on Day 1 of Treatment [Day 1]
The AHI is the number of apneas and hypopneas per hour of sleep. AHI less than 5 is considered normal. An AHI from 5 to 14 denotes mild sleep apnea, 15 to 30 is moderate, while a greater than 30 AHI is considered severe.
- OSA Cohort: AHI on Day 1 of Treatment [Day 1]
