A Study to Assess the Safety and Tolerability of Fezolinetant in Women Seeking Treatment for Relief of Vasomotor Symptoms (VMS) Associated With Menopause

Plain-language summary
This study is for women in menopause with hot flashes. Menopause, a normal part of aging, is the time of a woman's last period. Hot flashes can interrupt a woman's daily life. The purpose of this study is to find out how safe it is for these women to take fezolinetant long term (up to 52 weeks). To do that, the study will look at the number and severity of the "adverse events." Those are the side effects that study participants have while they are in the study. The study treatment is fezolinetant (1 tablet of fezolinetant) once a day. The study participants will take study treatment for 52 weeks. At weeks 2 and 4 and then once a month, the study participants will go the hospital or clinic for a check-up. They will be asked about medications, side effects and how they feel. Other checks will include physical exam and vital signs (heart rate, temperature and blood pressure). Blood and urine will be collected for laboratory tests. At some study visits, study participants will complete questionnaires that are about their quality of life. Study participants who still have their uterus will have 2 more tests done at the first and last study visits. One of the 2 tests is endometrial biopsy. This test involves removing a small amount of tissue from the inside lining of the uterus. The tissue is then checked under a microscope. The other test is transvaginal ultrasound. It uses sound waves to create pictures of the organs in the pelvis. The sound waves are transmitted by a probe (transducer), which is placed inside the vagina. Study participants may have a screening mammogram done at the first and/or last study visit. A mammogram is an x-ray picture of the breasts used to screen for breast cancer. Study participants who did not have this test done in the last 12 months will have it done at the first study visit. They will have it done at the last study visit if they are due for their screening mammogram and their own doctor agrees. The last check-up at the hospital or clinic will be 3 weeks after the last dose of study treatment.

Inclusion Criteria:
* Subject has a body mass index ≥ 16 kg/m\^2 and ≤ 38 kg/m\^2 at the screening visit.
* Subject confirmed as menopausal per 1 of the following criteria at the screening visit:
O Subject has spontaneous amenorrhea for \>= 12 consecutive months O Spontaneous amenorrhea for ≥ 6 months with biochemical criteria of menopause (follicle-stimulating hormone \[FSH\] \> 40 International Units per Liter \[IU/L\], or O Having had bilateral oophorectomy ≥ 6 weeks prior to the screening visit (with or without hysterectomy).
O FSH \> 40 IU/L if subjects received hysterectomy but still have ovary
* Subject is seeking treatment for relief for VMS associated with menopause.
* Subject is in good general health as determined on the basis of medical history and general physical examination, including a bimanual clinical pelvic examination and clinical breast examination devoid of relevant clinical findings, performed at the screening visit; hematology and biochemistry parameters; pulse rate and/or blood pressure; and ECG within the reference range for the population studied, or showing no clinically relevant deviations.
* Subject has documentation of a normal/negative or no clinically significant abnormal findings on mammogram (or echo) (e.g., \<BI-RADS class 4; obtained at screening or within the prior 12 months of screening). Appropriate documentation includes a written report or an electronic report indicating normal/negative or no clinically significant abnormal findin…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
