Brief summary
This study was for women in menopause with moderate to severe 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 study treatments were fezolinetant 30 milligrams (mg) (1 tablet of fezolinetant and 1 placebo tablet) once a day, fezolinetant 45 mg (2 tablets of fezolinetant) once a day or placebo (2 tablets) once a day. (Placebo was a dummy treatment that looks like medicine but did not had any medicine in it.) The study compared fezolinetant and placebo after 4 and 12 weeks of dosing. The study evaluated if fezolinetant reduces the number of hot flashes. And the study evaluated if fezolinetant reduces the severity of the hot flashes. Women in the study received an electronic handheld device at the first study visit. (It was similar to a smart phone.) Each day of the study, study participants used this to record their hot flashes. Their record for the 10 days before the start of study treatment was checked. They remained in the study if their record shown 7 or 8 moderate to severe hot flashes per day (50 or more per week). Next, they were picked for 1 of the 2 study treatments (fezolinetant or placebo) by chance alone. It was like flipping a coin. The study participants took study treatment for 52 weeks. The first 12 weeks of study treatment are double-blinded. That means that the study participants and the study doctors did not knew who took which of the study treatments (fezolinetant 30 mg, fezolinetant 45 mg or placebo) during that time. The last 40 weeks of study treatment are noncontrolled. That means that each study participant and the study doctors knew which study treatment that study participant took during that time. Women who took fezolinetant during the first 12 weeks continued to take the same dose. Women who took placebo during the first 12 weeks took fezolinetant. Their dose was either 30 mg or 45 mg fezolinetant. At weeks 2, 4, 8, 12, 14, 16 and then once a month, the study participants visited the hospital or clinic for a check-up. They were asked about medications, side effects and how they felt. Other checks included physical exam and vital signs (heart rate, temperature and blood pressure). Blood and urine was collected for laboratory tests. Study participants completed questionnaires that were about how hot flashes affect their daily life. Study participants who still had their uterus had the following 2 tests done at the first and last study visits. One of the 2 tests was endometrial biopsy. This test involves removing a small amount of tissue from the inside lining of the uterus. The tissue was then checked under a microscope. The other test is transvaginal ultrasound. This test used sound waves to create pictures of the organs in the pelvis. The sound waves were transmitted by a probe (transducer), which was 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 had this test done in the last 12 months had it done at the first study visit. They had 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 was 3 weeks after the last dose of study treatment.

| Change From Baseline in The Mean Frequency of Moderate to Severe VMS at Week 4 | Baseline and week 4 | The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency per week was derived by taking the mean of the data over 7 days. Moderate VMS was defined as sensation of heat with sweating/dampness, but participant was able to continue activity. If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Baseline was the average number of moderate to severe VMS per 24 hours based on the non-missing values in the 10 days immediately prior to randomization. |

| Number of Participants in Each Category of Patient's Global Impression of Change (PGIC) in VMS at Each Visit | Weeks 4, 12, 16, 20, 24, 28, 32, 36, 40, 48, 52 of fezolinetant exposure (weeks 16, 24, 28, 32, 36, 40, 44, 48 and 52 for arms Placebo/Fezolinetant 30 mg and Placebo/Fezolinetant 45 mg) | The PGI is comprised of 2 companion 1-item PRO measures analogous to the Clinical Global Impression (CGI) scales. These measures provide brief, stand-alone global assessments prior to and after initiating a study medication. Patient-perceived change from the initiation of treatment (PGI-C)-VMS is used to evaluate meaningful within-person changes over time in VMS. This measure provides patient-perceived change from the initiation of treatment. The PGI-C VMS asks: Compared to the beginning of this study, how would you rate your HFs/night sweats now? Subject ratings range from (1) much better to (7) much worse. Participant ratings range from 1=much better, 2= moderately better, 3= a little better, 4= no change, 5= a little worse, 6= moderately worse, 7= much worse. |
| Change From Baseline in The Mean Patient-reported Outcomes Measurement Information System Sleep Disturbance - Short Form 8b (PROMIS SD SF 8b) Total Score at Week 12 | Baseline and week 12 | 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 patients 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. |

If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Severity was zero for participants that had no mild or moderate or severe VMS. Higher scores indicates greater severity. |
| Number of Participants With Adverse Events | From first dose date up to 21 days after last dose (to 55 weeks) | 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 treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with use of a medicinal product (mp) whether or not considered related to the mp. An AE is considered serious if it results in death, is life-threatening, results in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, results in congenital anomaly or birth defect, requires inpatient hospitalization or leads to prolongation of hospitalization, hospitalization for treatment/observation/examination caused by AE is to be considered as serious, discontinuation due to increases in liver enzymes, other medically important events. TEAE was defined as an AE observed from first dose date up to 21 days after last dose. |

Outcome results
Primary
Change From Baseline in The Mean Frequency of Moderate to Severe VMS at Week 12
The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency per week was derived by taking the mean of the data over 7 days. Moderate VMS was defined as sensation of heat with sweating/dampness, but participant was able to continue activity. If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Baseline was the average number of moderate to severe VMS per 24 hours based on the non-missing values in the 10 days immediately prior to randomization.

Change From Baseline in The Mean Frequency of Moderate to Severe VMS at Week 4
The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency per week was derived by taking the mean of the data over 7 days. Moderate VMS was defined as sensation of heat with sweating/dampness, but participant was able to continue activity. If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Baseline was the average number of moderate to severe VMS per 24 hours based on the non-missing values in the 10 days immediately prior to randomization.
Time frame: Baseline and week 4
Population: Full analysis set (FAS) consisted of all participants who were randomized and received at least 1 dose of study intervention. The randomized treatment for each participant was used for summaries by treatment group based on the FAS, even if a participant erroneously received a different treatment. Participants with available data at specified time point were included.

Change From Baseline in The Mean Severity of Moderate to Severe VMS at Week 12
Severity of moderate to severe VMS per day at post baseline visit was calculated as follows: \[(number of mild hot flashes per day x 1) + (number of moderate hot flashes per day x 2) + (number of severe hot flashes per day x 3)\]/Total number of daily mild/moderate/severe hot flashes Moderate VMS was defined as sensation of heat with sweating/dampness, but participant was able to continue activity. If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Severity was zero for participants that had no mild or moderate or severe VMS. Higher scores indicates greater severity.

Change From Baseline in The Mean Patient-reported Outcomes Measurement Information System Sleep Disturbance - Short Form 8b (PROMIS SD SF 8b) Total Score at Week 12
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 patients 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.

Mean Percent Change in The Frequency of Moderate And Severe VMS From Baseline to Each Study Week Up to Week 12
The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency per week was derived by taking the mean of the data over 7 days. Moderate VMS was defined as sensation of heat with sweating/dampness, but participant was able to continue activity. If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Baseline was the average number of moderate to severe VMS per 24 hours based on the non-missing values in the 10 days immediately prior to randomization.
Time frame: Baseline and weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12

Number of Participants in Each Category of Patient's Global Impression of Change (PGIC) in VMS at Each Visit
The PGI is comprised of 2 companion 1-item PRO measures analogous to the Clinical Global Impression (CGI) scales. These measures provide brief, stand-alone global assessments prior to and after initiating a study medication. Patient-perceived change from the initiation of treatment (PGI-C)-VMS is used to evaluate meaningful within-person changes over time in VMS. This measure provides patient-perceived change from the initiation of treatment. The PGI-C VMS asks: Compared to the beginning of this study, how would you rate your HFs/night sweats now? Subject ratings range from (1) much better to (7) much worse. Participant ratings range from 1=much better, 2= moderately better, 3= a little better, 4= no change, 5= a little worse, 6= moderately worse, 7= much worse.
Time frame: Weeks 4, 12, 16, 20, 24, 28, 32, 36, 40, 48, 52 of fezolinetant exposure (weeks 16, 24, 28, 32, 36, 40, 44, 48 and 52 for arms Placebo/Fezolinetant 30 mg and Placebo/Fezolinetant 45 mg)

Secondary
Number of Participants With Adverse Events
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 treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with use of a medicinal product (mp) whether or not considered related to the mp. An AE is considered serious if it results in death, is life-threatening, results in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, results in congenital anomaly or birth defect, requires inpatient hospitalization or leads to prolongation of hospitalization, hospitalization for treatment/observation/examination caused by AE is to be considered as serious, discontinuation due to increases in liver enzymes, other medically important events. TEAE was defined as an AE observed from first dose date up to 21 days after last dose.
Time frame: From first dose date up to 21 days after last dose (to 55 weeks)
Population: Safety population included all randomized participants who took at least 1 dose of study intervention. A participant erroneously receiving a treatment different from their randomized treatment was assigned to the treatment group that the participant received as first dose.

Number of Participants With Mean Percent Reduction of 100% in The Mean Frequency of Moderate, and Severe VMS From Baseline to Each Study Week Up to Week 12
The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency per week was derived by taking the mean of the data over 7 days. Moderate VMS was defined as sensation of heat with sweating/dampness, but participant was able to continue activity. If at night, participant woke up because she was feeling hot and/or was sweating, but no action was necessary other than rearranging the bed sheets. Severe VMS was defined as sensation of intense heat with sweating, caused disruption of activity. If at night, participant woke up hot and was sweating and needed to take action (e.g., remove layers of clothes, open the window, or get out of bed). Baseline was the average number of moderate to severe VMS per 24 hours based on the non-missing values in the 10 days immediately prior to randomization. Participant has 100% reduction from baseline to each post baseline week for the frequency of moderate to severe VMS.
