Mean Change From Baseline in Hot Flash Severity at Week 4 and Week 8

A scale was not used to measure severity scores. Severity scores of hot flashes were calculated for each subject. The following formula was used to calculate severity. SS = (2•Fm + 3•Fs) ÷ (Fm + Fs) Where: SS = severity score Fm = frequency of moderate hot flashes Fs = frequency of severe hot flashes The mean number of moderate and severe hot flashes that was recorded in the Run-In Period was used to calculate the baseline severity score.

Change From Baseline in Climacteric Symptoms at Week 8

The Greene Climacteric Scale (GCS) was used for this measurement. The scale has 21 questions and measures symptoms in 4 areas; these are psychological (anxiety and depression), physical, vasomotor, and libido. The severity of the symptom was scored as: 0=none, 1=mild, 2=moderate, and 3=severe. Anxiety was determined by using the sum of scores 1 to 6, and depression was determined by using the sum of scores 7 to 11. Physical aspects were determined by using the sum of scores 12 to 18; vasomotor aspects were determined by using the sum of scores 19 to 20; and libido was determined by using the score for question 21. The total GCS score ranges from "0" to "63" which is the sum of all the scores for the 21-symptom assessment questions in this scale. Each subject's total GCS score at baseline and at Week 8 were used to calculate change from baseline in these symptoms. The change from baseline is reported below.

Change From Baseline in Hot Flash Composite Score at Week 4 and Week 8

A scale was not used for this measurement. Composite scores of hot flashes were calculated by using the following formula: CS = (2 • Fm + 3 • Fs) Where: CS = composite score Fm = frequency of moderate hot flashes Fs = frequency of severe hot flashes The mean number of moderate and severe hot flashes recorded in the Run-In Period was used to calculate the baseline composite score.

Effect of Brisdelle (Paroxetine Mesylate) Capsules on Mood at Week 4

Mood was measured using the Profile of Mood States (POMS) Questionnaire. The Profile of Moods States (POMS) is a 65-item multi-dimensional measure that provides a method of assessing transient, fluctuating active mood states. Key areas that are measured include: tension-anxiety, anger-hostility, fatigue-inertia, depression-dejection, vigor-activity, confusion-bewilderment. Responses to questions are scored with the following numerical values: Not at all = 1, A little = 2, Moderate = 3, Quite a bit = 4, Extremely = 5. A total score for a domain was obtained by summing the responses of individual items in the domain. The total POMS score can range from "65" to "335." The percentage of participants who had a change from baseline in the total score at Week 4 is reported below.

Effect of Brisdelle (Paroxetine Mesylate) Capsules on Improvement of Hot Flash Interference at Week 4

Interference of hot flashes was measured by using the Hot Flash-Related Daily Interference Scale (HFRDIS). The HFRDIS is a 10-item scale that measures the degree to which hot flashes interfere with 9 daily activities and the tenth item measures the degree to which hot flashes interfere with each of the other items. Subjects can score for each item on a scale from 0 to 10 where 0 = Do not interfere and a score of 10 = Completely interferes. The measure being reported below is percentage of responders who had an improvement in HFRDIS score at Week 4 compared to baseline. A responder is defined as a subject who had an improvement in the HFRDIS score. An improvement is define as a score ≤3 on each question.

Proportion of Clinical Global Impression (CGI) Responders at Week 4 and Week 8

The Clinical Global Impression Scale (CGIS) was completed by the investigator and was used to measure the severity of the VMS at any given time and the improvement from baseline. Responders were defined as subjects who achieved a score of 1 to 3 where 1 = very much improved, 2 = much improved, and 3 = minimally improved. Non-responders were defined as subjects who achieved a score of 4 to 7 where 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse.

Asses the Effect of Brisdelle (Paroxetine Mesylate) Capsules on the Interference on Sexual Functioning at Week 8

The Arizona Sexual Experiences Scale (ASEX) is a 5-item rating scale that quantifies sex drive, arousal, vaginal lubrication/penile erection, ability to reach orgasm, and satisfaction from orgasm. Possible total scores range from 5 to 30, with the higher scores indicating more sexual dysfunction. The sum of the scores for all 5 items was calculated.

Proportion of Numerical Rating Scale (NRS) True Responders at Week 4 and Week 8

The Subject Impression Numerical Rating Scale (NRS) is an 11-point scale was used to measure how bothered a subject was by hot flashes both during the day and the night. The measure being reported below is percentage of responders who had an improvement in NRS score at Week 4 compared to baseline. A responder is defined as a subject who had an improvement in the NRS score. An improvement is define as a score ≤3 on each question.
