A Study to Confirm if Fezolinetant Helps Reduce Hot Flashes in Chinese Women Going Through Menopause
- Registration Number
- NCT06812754
- Lead Sponsor
- Astellas Pharma Global Development, Inc.
- Brief Summary
Hot flashes are the most common reason women going through menopause seek medical attention. Hormone replacement therapy, or HRT, is most often prescribed to treat hot flashes. However, HRT can't be used by all women or for as long as may be needed.
Fezolinetant is approved in several countries to treat hot flashes in women going through menopause. Further studies are needed before it is available in other regions such as Asia.
The goal of this study is to confirm if fezolinetant helps reduce hot flashes in Chinese women going through menopause. This study will also confirm the safety of fezolinetant and how well the women cope with (tolerate) the treatment. The women will take 1 tablet of the study medicine either fezolinetant or placebo once a day for up to 12 weeks. This is decided by chance alone. The placebo looks like fezolinetant but will not have any medicine in it.
Women that want to take part in the study will be given an electronic handheld device with an app to track their hot flashes and night sweats. The women will record this information before, during and after taking the study treatment. During the study, the women will visit the study clinic several times. At each visit they will be asked if they had any medical problems. The women will have general safety checks. At some visits, a breast ultrasound (mammogram), cervical smear, and ultrasound of the womb (uterus) may be done.
The last clinic visit will be 3 weeks after the women take their final tablet of the study medicine (fezolinetant or placebo).

-
Participant has previously been enrolled in a clinical trial with fezolinetant or other neurokinin (NK) receptor antagonists.
