Hot Flashes, Vasomotor Symptoms Associated With Menopause

Menopause
Brief summary
Researchers are looking for a better way to treat women who have hot flashes after they have been through the menopause. Hot flashes are caused by the hormonal changes that happen when a woman's body has been through the menopause. Menopause is when women stop having a menstrual cycle, also called a period. During the menopause, the ovaries increasingly produce less sex hormones as a result of the natural ageing process and related hormonal adjustments. The decline in hormone production can lead to various symptoms which, in some cases, can have a very adverse effect on a menopausal woman's quality of life. The study treatment, elinzanetant, was developed to treat symptoms caused by hormonal changes. It works by blocking a protein called neurokinin from sending signals to other parts of the body, which is thought to play a role in starting hot flashes. There are treatments for hot flashes in women who have been through the menopause, but may cause medical problems for some people. In this study, the researchers will learn how well elinzanetant works compared to a placebo in women who have been through the menopause and have hot flashes. A placebo is a treatment that looks like a medicine but does not have any medicine in it. To compare these study treatments, the participants will record information about their hot flashes in an electronic diary. The researchers will study the number of hot flashes the participants have and how severe they are. They will study the results from before treatment and after 12 weeks of treatment. The participants in this study will take two capsules of either elinzanetant or the placebo once a day. The participants will take the study treatments for 52 weeks. During the study, the participants will visit their study site approximately 11 times and perform 2 visits by phone. Each participant will be in the study for approximately 62 weeks. During the study, the participants will: * record information about their hot flashes in an electronic diary * answer questions about their symptoms The doctors will: * check the participants' health * take blood samples * ask the participants questions about what medicines they are taking and if they are having adverse events An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
Interventions
120 mg elinzanetant orally once daily
Matching placebo orally once daily.

Eligibility
Inclusion criteria
* Postmenopausal, defined as: 1. at least 12 months of spontaneous amenorrhea prior to signing of informed consent, or 2. at least 6 months of spontaneous amenorrhea prior to signing of informed consent with serum follicle-stimulating hormone (FSH) levels \> 40 mIU/mL and a serum estradiol concentration of \< 30 pg/mL, or 3. at least 6 months after hysterectomy at signing of informed consent with serum FSH levels \> 40 mIU/mL and a serum estradiol concentration of \< 30 pg/mL, or 4. surgical bilateral oophorectomy with or without hysterectomy at least 6 weeks prior to signing of informed consent. * Moderate to severe hot flash (HF) associated with the menopause and seeking treatment for this condition. * Participant has completed Hot Flash Daily Diary (HFDD) for at least 11 days during the two weeks preceding baseline visit and is showing eligibility with respect to previous inclusion criterion during this time period.
Exclusion criteria
* Any clinically significant prior or ongoing history of arrhythmias, heart block and QT prolongation either determined through clinical history or on ECG evaluation. * Any active ongoing condition that could cause difficulty in interpreting vasomotor symptoms (VMS) such as: infection that could cause pyrexia, pheochromocytoma, carcinoid syndrome. * Current or history (except complete remission for 5 years or more) of any malignancy (except basal and squamous cell skin tumors).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Change in Frequency of Moderate to Severe Hot Flashes (HFs) From Baseline to Week 12 (Assessed by Hot Flash Daily Diary [HFDD]) | Baseline to Week 12 | The HFDD items assess the number of mild, moderate, and severe HF experienced during the day and during the night. Mild HF are defined as a sensation of heat without sweating, moderate HF are defined as a sensation of heat with sweating, but able to continue activity, and severe HF are defined as a sensation of heat with sweating, causing cessation (stopping) of activity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mean Change in Patient-reported Outcomes Measurement Information System Sleep Disturbance Short Form 8b (PROMIS SD SF 8b) Total T-score From Baseline Over Time. | Baseline to Week 56 | The PROMIS SD SF 8b includes 8 items assessing sleep disturbance over the past 7 days. Items assess sleep quality, sleep depth and restoration associated with sleep, perceived difficulties with getting to sleep or staying asleep and perceptions of the adequacy of and satisfaction with sleep. Participants respond to the items on a 5-point scale from not at all, never or very poor to very much, always or very good. Four of the items are scored reversely. Individual item scores are aggregated to total raw scores which range from 8 to 40. Total raw scores are converted into T-scores for comparison with population norms, with a mean of 50 and standard deviation of 10. T-scores range from 28.9 to 76.5. For both raw and T-scores higher scores indicate greater severity of sleep disturbance. According to available score cut points from PROMIS developers, T-scores can be interpreted as indicating mild (55-59), moderate (60-69), or severe (\>70) sleep disturbance. |
| Mean Change in Menopause Specific Quality of Life Scale (MENQOL) Total Score From Baseline Over Time | Baseline to Week 56 | The MENQOL questionnaire is comprised of 29 items assessing the presence of menopausal symptoms and the impact of menopause on health-related quality of life over the past week. The items assess four domains of symptoms and functioning: Vasomotor functioning, psychosocial functioning, physical functioning, and sexual functioning. For each item, the participant indicates if they have experienced the symptom (yes/no). If they select yes, they rate how bothered they were by the symptom using a six-point verbal descriptor scale, with response options ranging from 0 'not at all bothered' to 6 'extremely bothered'. Based on the individual responses, item scores, domain scores, and a total MENQOL score are calculated. Each score ranges from 1-8, higher scores indicate greater bother. |
