PrimaryCo-Primary Efficacy Endpoint: Change From Baseline (CFB) in The Mean Frequency of Moderate to Severe Vasomotor Symptoms (VMS) at Week 4Baseline and week 4
The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency and severity 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 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).
PrimaryCo-Primary Efficacy Endpoint: Change From Baseline in The Mean Frequency of Moderate to Severe VMS at Week 12Baseline and week 12
The frequency of moderate to severe VMS was the number of moderate to severe VMS per 24 hours. A daily frequency and severity 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 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).
PrimaryCo-Primary Efficacy Endpoint: Change From Baseline in The Mean Severity of Moderate to Severe VMS at Week 4Baseline and week 4
Severity of moderate to severe VMS per day was calculated as follows: \[(number of moderate VMS × 2) + (number of severe VMS × 3)\]/number of daily moderate/severe VMS. Moderate VMS was defined as sensation of heat with sweating/dampness, but 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 moderate or severe VMS. Higher score indicates greater severity.
PrimaryCo-Primary Efficacy Endpoint: Change From Baseline in The Mean Severity of Moderate to Severe VMS at Week 12Baseline and week 12
Severity of moderate to severe VMS per day was calculated as follows: \[(number of moderate VMS × 2) + (number of severe VMS × 3)\]/number of daily moderate/severe VMS. Moderate VMS was defined as sensation of heat with sweating/dampness, but 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 moderate or severe VMS. Higher scores indicates greater severity.
SecondaryChange From Baseline in The Mean Frequency of Mild, Moderate, and Severe VMS to Each Study WeekBaseline and weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15
The frequency of mild, moderate and severe VMS was the number of mild, moderate and severe VMS per 24 hours. A daily frequency and severity per week was derived by taking the mean of the data over 7 days. Mild VMS was defined as sensation of heat without sweating/dampness. If at night, subject does not wake up but later notices damp sheets or clothing. Moderate VMS was defined as sensation of heat with sweating/dampness, but 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).
SecondaryChange From Baseline in The Mean Frequency of Moderate and Severe VMS to Each Study WeekBaseline and weeks 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 13, 14 and 15

Moderate VMS was defined as sensation of heat with sweating/dampness, but 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).
SecondaryChange From Baseline in The Mean Severity of Mild, Moderate, and Severe VMS to Each Study WeekBaseline and weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15
Severity of mild, moderate \& severe VMS per day was calculated as follows \[(number of mild VMS × 1) + (number of moderate VMS × 2) + (number of severe VMS × 3)\]/number of daily mild/moderate/severe VMS Mild VMS was defined as sensation of heat without sweating/dampness. If at night, participant did not wake up but later noticed damp sheets or clothing. Moderate VMS was defined as sensation of heat with sweating/dampness, but 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 \& was sweating \& needed to take action Severity was zero for participants that had no moderate or severe VMS. Higher score indicates greater severity.
SecondaryChange From Baseline in The Mean Severity of Moderate and Severe VMS to Each Study WeekBaseline and weeks 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 13, 14 and 15
