Brief Summary

This study is being done to compare two forms of the medicine elinzanetant, which is used to help manage hot flush symptoms related to changes in female hormones. The researchers want to find out whether a new tablet form of elinzanetant is absorbed and processed by the body of healthy women in a similar way than an existing capsule form. About 100 healthy women aged 18 to 65 will take part in this study. Each participant will receive both forms of the medicine at different times during the study. They will take the medicine once daily for several days under controlled conditions at a study center, and blood samples will be collected to measure how the body absorbs and handles the drug. The study is designed so that each participant can be compared to herself, helping researchers clearly understand any differences between the two formulations.

Outcome Measures

Primary Outcomes (3)

• Area Under the Plasma Concentration-Time Curve Over 24 Hours After Multiple Dosing (AUC(0-24)md)

  elinzanetant administered in the evening 3 hours after a light dinner.

  On Day 11 of each 12-day treatment period (study intervention administered on Days 1-10)

• Maximum Observed Plasma Concentration After Multiple Dosing (Cmax,md)

  elinzanetant administered in the evening 3 hours after a light dinner.

  On Day 11 of each 12-day treatment period (study intervention administered on Days 1-10)

• Minimum Observed Plasma Concentration During Dosing Interval After Multiple Dosing (Cmin,md)

  elinzanetant administered in the evening 3 hours after a light dinner.

  On Day 11 of each 12-day treatment period (study intervention administered on Days 1-10)

Secondary Outcomes (3)

• Number and Severity of Treatment-Emergent Adverse Events (TEAEs)

  From first dose of study intervention through Day 12 of Period 2 (each treatment period is 12 days)

• Area Under the Plasma Concentration-Time Curve Over 24 Hours After Single Dose (AUC(0-24))

  On Day 2 of each 12-day treatment period

• Maximum Observed Plasma Concentration After Single Dose (Cmax)

  On Day 2 of each 12-day treatment period
