A Study of BAY3427080 (NT-814) in the Treatment of Moderate to Severe Post-menopausal Vasomotor Symptoms

Mean Change From Baseline in Frequency of Mean Daily Moderate and Severe Hot Flushes From Baseline to Weeks 1, 2, 8 and 16

Participants recorded daily in their electronic diary (eDiary) the frequency and severity of hot flushes during the treatment period. The baseline assessment for hot flushes was calculated using the last 7 days (not necessarily consecutive days) with an available data in the evening and/or the morning of the baseline diary completion period. A diary day was comprised of the evening entry of this day and the morning entry of the following day, in that order. Mean daily frequency = Sum of number of hot flushes filled in the diary during the last 7 diary days (with at least one available data in the evening and/or morning) divided by 7. Moderate: Sensation of heat with sweating, but able to continue activity. Severe: Sensation of heat with sweating, causing cessation (stopping) of activity.

Time frame: From baseline to Weeks 1, 2, 8 and 16

Mean Change From Baseline in Mean Severity of Moderate and Severe Hot Flushes From Baseline to Weeks 1, 2, 8 and 16

Mean weekly severity = (number of moderate hot flushes for 7 days) x 2 + (number of severe hot flushes for 7 days) x 3\] / (total number of moderate to severe hot flushes over 7 days). Severity is graded by the women from 1 to 3 (1 = mild; 2 = moderate; 3 = severe).

Time frame: From baseline to Weeks 1, 2, 8 and 16

A diary day was comprised of the evening entry of this day and the morning entry of the following day, in that order. Mean daily frequency = Sum of number of hot flushes filled in the diary during the last 7 diary days (with at least one available data in the evening and/or morning) divided by 7.

Each morning upon waking, subjects recorded the number of times they woke up in the night and the total number of hot flushes of each severity experienced during the night.

Time frame: From baseline to Weeks 1, 2, 4, 8, 12 and 16

Each morning upon waking, subjects recorded the number of times they woke up in the night and the total number of hot flushes of each severity experienced during the night. Night-time awakenings secondary to hot flashes corresponded to severe hot flash recorded on the morning diary, and all NTAs corresponded to the data recorded in the "Total number of times you woke up last night?" field from the eDiary recorded in the morning. Number of NTAs secondary to hot flushes could not be higher than the number of all NTAs.

Time frame: From baseline to Weeks 1, 2, 4, 8, 12 and 16

Change From Baseline in the Global and Individual Domain Scores of the Pittsburgh Sleep Quality Index (PSQI) at Weeks 4, 8, 12 and 16

The PSQI is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. The PSQI uses 19 individual items to generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction, each scored 0 (no difficulty) to 3 (severe difficulty). The sum of scores for these seven components yields one global score (range 0 to 21). Higher scores indicated worse sleep quality.

The ISI comprises seven items assessing the perceived severity of difficulties initiating sleep, staying asleep, and early morning awakenings, satisfaction with current sleep pattern, interference with daily functioning, noticeability of impairment attributed to the sleep problem, and degree of distress or concern caused by the sleep problem. Participants rated each item on a scale of 0 to 4, yielding a total score ranging from 0 to 28. The total score was calculated by adding the scores for all seven items. Higher scores indicated severe insomnia.

Time frame: From baseline to Weeks 4, 8, 12 and 16

For each of the 10 items, participants rated how much hot flushes had interfered with that aspect of their life on a scale of 0 (not at all) to 10 (very much so). The total score was calculated by adding the scores for all 10 items. Higher scores indicated greater interference.

Time frame: From baseline to Weeks 2, 4, 8, 12 and 16

Change From Baseline in the Menopause-specific Quality-of-Life Questionnaire Intervention Version (MenQoL-I) Scores at Weeks 4, 8, 12 and 16

The MenQoL-I is a validated questionnaire used to measure condition-specific quality of life in menopausal women. It is composed of 32 items across four domains (physical, vasomotor, psychosocial and sexual). For each item, participants recorded whether they had experienced the problem in the past month, and if so, they rated how bothered they were by the problem on a scale of 0 (not at all bothered) to 6 (extremely bothered). The item scores were converted to a score ranging from 1 to 8. Domain scores are calculated by averaging the converted individual item scores (range 1-8) related to the respective domain. (Domains: Vasomotor - items 1 to 3, Psychosocial - items 4 to 10, Physical- items 11- to 26, Sexual - items 27 to 29). For a MENQOL total score the aggregated mean of the mean domain scores is calculated. Higher scores indicate greater bother.

It is composed of items relating to symptoms of depression such as hopelessness and irritability, cognitions such as guilt or feelings of being punished, as well as physical symptoms such as fatigue, weight loss, and lack of interest in sex. Participants rated each item on a scale of 0 to 3 to give a total score ranging from 0 to 63, with a higher score suggesting more severe depressive symptoms.

It rates an individual's degree of suicidal ideation on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The version used was the eC-SSRS, which is a subject-reported version of the scale. Shifts from baseline versus post-baseline to demonstrate changes in categories (cat) were reported using cat 1 (No Suicidal Ideation or Behaviour), cat 2 (Suicidal Ideation) and cat 3 (Suicidal Behaviour).
