A Study of Fezolinetant to Treat Hot Flashes in Women Going Through Menopause
- Registration Number
- NCT05033886
- Lead Sponsor
- Astellas Pharma Global Development, Inc.
- Brief Summary
This study is for women in menopause who have moderate to severe hot flashes. It is for women who are unable to use hormone replacement therapy (HRT). Menopause, a normal part of life, is the time after a woman's last period. Hot flashes often occur during menopause. They can disrupt a woman's daily life.
The study medicines (also called investigational products, or IP) are tablets of fezolinetant or placebo. An investigational product means that the product is not yet licensed. In this study, a placebo is a dummy treatment that looks like fezolinetant but does not have any medicine in it. The study will compare fezolinetant with the placebo to learn if fezolinetant reduces the number and severity of hot flashes.
Women that want to take part in the study will be given an electronic handheld device with an app to track their hot flashes. Some women may be able to use the app on their own smartphone. In the last 10 days before their next clinic visit, the women will record information about their hot flashes. They can take part in the study if they have an average of 7 or more moderate to severe hot flashes each day. Women will be picked for 1 of 2 treatments (fezolinetant or placebo) by chance alone.
Women who take part in the study will take 2 tablets every day for 24 weeks. Treatment will be double-blinded. That means that the women in the study and the study doctors will not know who takes which of the study medicines (fezolinetant or placebo). The women will continue recording information about their hot flashes on the electronic device or their phone. They will also use another device to answer questions about how hot flashes affect their daily life.
During the study, the women will visit their study clinic several times for a check-up. This will happen during Weeks 2, 4, 8, 12, 16, 20, 24, and 27. Some women may be able to have home visits instead, from Week 2 to Week 20. At the check-up, they will be asked if they have any medical problems. Other checks will include vital signs (heart rate, temperature and blood pressure) and some blood samples taken for laboratory tests. At some check-ups, the women will have a physical exam. In Week 2 and Week 24, the women will have an ECG to check their heart rhythm. Women who have a uterus will also have a test called a transvaginal ultrasound. A probe is gently placed inside the vagina. Sound waves will create a picture of the organs in the pelvis. This will allow the study doctor to look more closely at the uterus and surrounding organs.
The last check-up (at Week 27) will be 3 weeks after they take their last tablets of study medicine (fezolinetant or placebo).

Group Intervention Description placebo placebo Participants receive placebo matched to fezolinetant tablets orally once daily for 24 weeks of treatment. fezolinetant fezolinetant Participants receive fezolinetant 45 milligrams (mg) (one 30 mg tablet and one 15 mg tablet) orally once daily for 24 weeks of treatment.
- Primary Outcome Measures
Name Time Method Mean change in the frequency of moderate to severe VMS from baseline at week 24 Baseline, week 24 The frequency of moderate to severe VMS is the number of moderate to severe VMS per 24 hours. A daily frequency per week is derived by taking the mean of the data over 7 days. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, caused disruption of activity.
- Secondary Outcome Measures
Name Time Method Mean change in severity of moderate to severe VMS from baseline at weeks 1, 4, 8, 12, 16 and 20 Baseline, weeks 1, 4, 8, 12, 16 and 20 Severity of moderate to severe VMS per day is calculated as follows: \[(number of moderate HFs × 2) + (number of severe HFs/day × 3)\]/number of daily moderate/severe HFs. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, causing cessation of activity. Severity is zero for participants that have had no moderate or severe VMS. Higher score indicates greater severity. A negative change indicates a reduction/improvement.
Mean percent change in the frequency of moderate to severe VMS from baseline at weeks 1, 4, 8, 12, 16, 20 and 24 Baseline, weeks 1, 4, 8, 12, 16, 20 and 24 The frequency of moderate to severe VMS is the number of moderate to severe VMS per 24 hours. A daily frequency per week is derived by taking the mean of the data over 7 days. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, caused disruption of activity.
Mean change in the severity of moderate to severe VMS from baseline at week 24 Baseline, week 24 Severity of moderate to severe VMS per day is calculated as follows: \[(number of moderate Hot Flashes (HFs) × 2) + (number of severe HFs/day × 3)\]/number of daily moderate/severe HFs. Moderate VMS is defined as sensation of heat with sweating but able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, causing cessation of activity. Severity is zero for participants that have had no moderate or severe VMS. Higher score indicates greater severity. A negative change indicates a reduction/improvement.
Mean change in the patient-reported sleep disturbance by the Patient-reported Outcomes Measurement Information System Sleep Disturbance - Short Form 8b (PROMIS SD SF 8b total score) from baseline at week 24 Baseline, week 24 The PROMIS SD SF 8b assesses self reported sleep disturbance over the past 7 days and includes perceptions of restless sleep; satisfaction with sleep; refreshing sleep; difficulties sleeping, getting to sleep or staying asleep; amount of sleep; and sleep quality. Because it assesses the participants experience of sleep disturbance, the measure does not focus on specific sleep-disorder symptoms or ask participants to report objective measures of sleep (e.g., total amount of sleep, time to fall asleep and amount of wakefulness during sleep). Responses to each of the 8 items range from 1 (no disturbed sleep) to 5 (disturbed sleep), and the range of possible summed raw scores is 8 to 40. Higher scores on the PROMIS SD SF 8b indicate more of the disturbed sleep. A negative value indicates a better outcome.
Mean change in the frequency of moderate to severe VMS from baseline at weeks 1, 4, 8, 12, 16 and 20 Baseline, weeks 1, 4, 8, 12, 16 and 20 The frequency of moderate to severe VMS is the number of moderate to severe VMS per 24 hours. A daily frequency per week is derived by taking the mean of the data over 7 days. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, caused disruption of activity.
Number of participants with percent reduction of >/= 50% in the frequency of moderate to severe VMS from baseline at weeks 1, 4, 8, 12, 16, 20 and 24 Baseline, weeks 1, 4, 8, 12, 16, 20 and 24 The frequency of moderate to severe VMS is the number of moderate to severe VMS per 24 hours. A daily frequency per week is derived by taking the mean of the data over 7 days. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, caused disruption of activity.
Number of participants with percent reduction of >/= 75% in the frequency of moderate to severe VMS from baseline at weeks 1, 4, 8, 12, 16, 20 and 24 Baseline, weeks 1, 4, 8, 12, 16, 20 and 24 The frequency of moderate to severe VMS is the number of moderate to severe VMS per 24 hours. A daily frequency per week is derived by taking the mean of the data over 7 days. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, caused disruption of activity.
Number of participants with percent reduction at 100% in the frequency of moderate to severe VMS from baseline at weeks 1, 4, 8, 12, 16, 20 and 24 Baseline, weeks 1, 4, 8, 12, 16, 20 and 24 The frequency of moderate to severe VMS is the number of moderate to severe VMS per 24 hours. A daily frequency per week is derived by taking the mean of the data over 7 days. Moderate VMS is defined as sensation of heat with sweating/dampness but is able to continue activity. Severe VMS is defined as sensation of intense heat with sweating, caused disruption of activity.
Number of participants with Treatment Emergent Adverse Events (TEAEs) From first dose to week 27 An AE is any untoward medical occurrence in a participant administered a study drug, which does not necessarily have to have a causal relationship with this treatment. An AE can be any unfavorable \& unintended sign, symptom, or disease temporally associated with the use of medicinal product (MP) whether considered related to MP. A TEAE was defined as an AE observed after starting administration of study intervention and up to 21 days after the last dose of study intervention.
