Study 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.

Frequently Asked Questions
While some clinical trials may focus on more advanced cancers, many trials are open to patients at various stages of their cancer. Each study has rules about who can take part. For example, only patients in a certain age group or those who have a certain type of tumor may be able to join.
Sometimes researchers want participants to keep taking their current treatments during a clinical trial. Other times, you may need to stop your current treatments for a while. If the investigational treatment doesn't work, you can usually go back to your original treatment plan.
In cancer clinical trials, a placebo is only used if there is no other treatment for that type of cancer. This helps compare an investigational treatment to the placebo. Placebos are rarely used in cancer trials because the best available treatment, called the “standard of care”, is usually given instead.
Your doctor may not know about all the opportunities for clinical trials that are available to you. Talk to your doctor or other medical provider about clinical trial information that you find. They can help you decide if a clinical trial is right for you. If you do not find any options on this website, we recommend you visit an online public registry website like clinicaltrials.gov to see a wide variety of available clinical trials.
