Registration Number
NCT06580587
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

The goal of this study is to learn how MK-8527 moves through the healthy person's body over time. Researchers will measure for the amount of MK-8527 in breast milk that the baby will receive at many time points.

Inclusion Criteria

The key inclusion criteria include but are not limited to the following:

  • Is at least 6 weeks postpartum at the time of administration of study intervention, following the delivery of a healthy singleton neonate
  • Is willing and able to express breast milk at least twice daily for at least 120 hours after enrollment
  • Is willing to discontinue breastfeeding from the time of administration of study intervention until at least 6 weeks following the administration of study intervention. This includes the avoidance of both directly breastfeeding and the administration of breast milk pumped during the above-specified time frame to the infant. Is willing to confirm with the site that the infant is able to bottle feed (breast milk) prior to Day 1 and that alternative nutrition (i.e., previously stored breast milk or infant formula) is available for feeding the infant through the 6-week post dose period
Exclusion Criteria

The key exclusion criteria include but are not limited to the following

  • Has a history of clinically significant endocrine, gastrointestinal (GI), cardiovascular, hematological, hepatic, immunological, renal, respiratory, genitourinary, psychiatric, or major neurological (including stroke and chronic seizures) abnormalities or diseases
  • Had mastitis within 30 days prior to administration of study drug
  • Has a positive pregnancy test at the time of screening or prior to treatment allocation

Primary Outcome Measures
NameTimeMethod
Area Under the Concentration-Time Curve from Time 0 to 120 hours (AUC0-120hrs) After Administration of a Single Oral Dose of MK-8527 in Breast MilkPredose and at designated timepoints up to 120 hours postdose

Breast milk samples will be collected to determine the AUC0-120hrs after administration of a single oral dose of MK-8527.

Maximum Breast Milk Concentration (Cmax) After Administration of a Single Oral Dose of MK-8527Predose and at designated timepoints up to 21 days postdose

Breast milk samples will be collected to determine the Cmax after administration of a single oral dose of MK-8527.

Time to Maximum Breast Milk Concentration (Tmax) After Administration of a Single Oral Dose of MK-8527Predose and at designated timepoints up to 21 days postdose

Breast milk samples will be collected to determine the Tmax after administration of a single oral dose of MK-8527.
