Evaluation of Possible Ways the Body May Process Two Different Forms of Elinzanetant in Healthy Study Participants

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.
