ClinConnect Summary

This clinical trial is studying a new treatment called CL25216 to see if it can help reduce hot flashes and other related symptoms that women often experience during perimenopause—the time when a woman’s body starts transitioning toward menopause. Women who join the study will either receive the study medication (250 mg once a day) or a placebo, which is a pill without the active medicine, so researchers can compare the effects.

The study is looking for healthy women between 40 and 55 years old who are overweight (with a body mass index between 25 and 29) and who have noticed changes in their menstrual cycles for at least three months. Participants also need to have certain hormone levels and no serious health problems, such as heart disease or recent hormone treatments. Women who join will need to agree to use birth control during the study if they can become pregnant, and they will undergo regular health checks. The study is not yet recruiting, but if eligible, participants can expect to be closely monitored to see how well CL25216 works in easing their symptoms and to ensure their safety throughout the trial.
