A Study to Evaluate Lemborexant in Milk of Healthy Lactating Women

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

The primary purpose of the study is to estimate the cumulative amount of lemborexant excreted in breast milk following a single dose administration of lemborexant 10 milligram (mg) to healthy lactating women and to estimate the relative infant dose (RID) expressed as a percent of the daily maternal dose.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: accepted.

You may qualify if…

• Is a healthy lactating female at least 18 years of age and willing to sign an informed consent prior to any study-related activities.
• The participant must have had a normal term pregnancy and has been actively breastfeeding or pumping for at least 5 weeks postpartum; lactation must be well-established and the mother not experiencing problems with feeding her infant breast milk. Participants planning on weaning their infants independent of study participation, who meet aforementioned requirements, will be considered for enrolment in the study.
• Is willing not to breastfeed for 11 days after the study drug administration.
• Breastfeeds an infant who is already able to feed from a bottle.
• Agrees to collect all breast milk from predose to end of the study using an electric pump provided by the sponsor.
• Is considered reliable and capable of adhering to the protocol and visit schedule according to the judgment of the investigator.

You may not qualify if…

• Has a positive pregnancy test at Screening or Baseline.
• Evidence of disease that may influence the outcome of the study within 4 weeks before dosing; example, psychiatric disorders and disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system, or participants who have a congenital abnormality in metabolism.
• Any history of gastrointestinal surgery that may affect pharmacokinetic (PK) profiles, example, hepatectomy, nephrectomy, digestive organ resection (but not cholecystectomy) at Screening or Baseline.
• Any clinically abnormal symptom or organ impairment found by medical history at Screening, and physical examinations, vital signs, ECG finding, or laboratory test results that require medical treatment at Screening or Baseline.
• A prolonged QT interval by Fridericia (QTcF) (QTcF greater than [>] 450 milliseconds [ms]) as demonstrated by a repeated ECG at Screening.
• Any suicidal behavior (per the Suicidal Behavior section of the Columbia-Suicide Severity Rating Scale) within 10 years of Screening.
• Evidence of clinically significant disease (example, cardiac, respiratory, gastrointestinal, renal disease) that in the opinion of the investigator(s) could affect the participant's safety or interfere with the study assessments.
• Exposure within the last 14 days to an individual with confirmed or probable coronavirus disease (COVID-19) or symptoms within the last 14 days that are on the most recent centers for disease control and prevention (CDC) list of COVID symptoms or any other reason to consider the participant at potential risk for an acute COVID-19 infection.
• Has mastitis or other condition that would prevent the collection of milk from one or both breasts.
• Is a smoker (>5 cigarettes, or nicotine equivalent, per day).
• Has a positive result for urine drug screening.
• Has undergone surgery (other than caesarean section) or donated blood within 8 weeks prior to the start of the study.
• Used any prescription or over-the-counter medications, which may impact plasma concentration of lemborexant, within 1 week or 5 half-lives, whichever is longer, before Screening.
• Hypersensitivity to the study drug or any of the excipients.
• History of or has concomitant medical condition(s) that in the opinion of the investigator(s) would compromise the participant's ability to safely complete the study.
• History of drug or alcohol dependency or abuse within approximately the last 2 years.
• Currently enrolled in another clinical study or used any investigational drug or device within 28 days or 5*the half-life, whichever is longer preceding informed consent.
• Known to be human immunodeficiency virus (HIV) positive at Screening.
• Active viral hepatitis (B or C) as demonstrated by positive serology at Screening.
• Has a current or prior diagnosis of narcolepsy.
