Trial Outcomes & Findings for Study to Evaluate the Respiratory Safety of Lemborexant in Adult and Elderly Healthy Subjects and Adult and Elderly Subjects With Mild Obstructive Sleep Apnea (NCT NCT03471871)
NCT ID: NCT03471871
Last Updated: 2020-02-17
Results Overview
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).

Participant Flow
Participants took part in the study at 8 investigative sites in the United States from February 21, 2018 to August 3, 2018.
In healthy volunteer (HV) cohort, 39 participants were screened and enrolled, of which 22 were screen failures, 17 were randomized to receive treatment. In obstructive sleep apnea (OSA) cohort, 107 participants were screened and enrolled, of which 68 were screen failures, 39 were randomized to receive treatment. Total participants enrolled=146

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 PSG.
