Study Summary
This trial is testing a new hormone to treat hot flashes and other menopause symptoms. It is testing how well it works and how safe it is.

They must be in good health, have a normal mammogram, and if not hysterectomized, have a thin endometrial lining and no abnormal biopsy results. Women with high blood pressure, clotting disorders, severe liver or kidney disease, certain psychiatric conditions or recent drug trials cannot participate.Check my eligibility
What is being tested?
The E4Comfort Study I is testing Estetrol (E4) tablets at two doses against placebo to see how well they reduce the severity and frequency of menopause-related hot flashes. The study has two parts: one for efficacy (how well it works) and another for safety (looking at any potential risks).See study design
What are the potential side effects?
Possible side effects of Estetrol may include typical hormone therapy reactions like nausea, headaches, breast tenderness or swelling. There's also a risk of more serious issues such as blood clots or elevated blood pressure.
