61The purpose of this study is to assess the efficacy and safety of repeated administration of G-CSF for the treatment of hot flashes and vasomotor symptoms in women with naturally-occurring or surgically induced menopause. G-CSF will be administered three times at 28 day intervals to postmenopausal women, ages 40 to 65, suffering at least 49 moderate to severe hot flashes per week.
This is a 12-week, multicenter, randomized, double-blind, placebo-controlled study. Eligible subjects will be stratified by natural or surgical menopause and randomized (1:1) to receive 3 single injections, 28-days apart, of either G-CSF or placebo.
This study will consist of a 14-21 day screening period. Subjects enrolled will be given three single 1.0 mL subcutaneous (SC) injections (repeated 28-days apart), in the outer area of either upper arm, of either G-CSF or placebo (sterile physiological saline) at Baseline, Day 28 and Day 56. Subjects will be followed for 12 weeks and will complete hot flash diary entries every day for the duration of treatment. Safety will be assessed by adverse events, clinical laboratory tests (clinical chemistry and complete blood count with differential) and vital signs. A follow-up phone call will occur 60 days after the last dose of study drug.
Eligibility will be assessed via physical examination, clinical laboratory testing, vital signs.
Subjects will receive a diary in which to record daily hot flashes symptoms during the duration of the screening period. Subjects must have at least 14 days of hot flash recordings to participate in the study. The diary will be reviewed by study site staff on Baseline (Day 0) to confirm study eligibility.
During the treatment period, subjects will return to the study site at Days 1, 21, 28, 29, 49, 56, 57, and 84 for assessments.
The follow-up phone call will occur approximately 60 days following the last dose of study drug.

An adverse event (AE) is any untoward medical occurrence, including the exacerbation of a pre-existing condition, in a subject or clinical investigation subject administered a pharmaceutical product. This does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is any experience that suggests a significant hazard, contraindication, side effect, or precaution. This includes any experience that results in death; is acutely life-threatening; requires inpatient hospitalization or prolongs the existing hospitalization; results in persistent or significant incapacity or substantial disruption of ability to conduct normal life functions; is a congenital anomaly/birth defect; or requires medical or surgical intervention to prevent one of the outcomes listed above.

The frequency of moderate to severe hot flashes was the number of moderate to severe hot flashes per 24 hours. A daily frequency per week was derived by taking the mean of the data over 7 days. All subjects who were randomized and received at least one dose of study drug are included in this subset. Subjects are analysed according to the randomized treatment group regardless of treatment received.

Subjects are analysed according to the randomized treatment group regardless of treatment received. Severity was zero for participants that had no mild or moderate or severe VMS. Higher scores indicates greater severity.

Menopause-specific Quality of Life (MENQOL) Questionnaire. The MENQOL is self-administered and consists of a total of 29 items in a Likert-scale format. Each item assesses the impact of one of four domains of menopausal symptoms, as experienced over the last month: vasomotor (items 1-3), psychosocial (items 4-10), physical (items 11-26), and sexual (items 27-29). MENQOL VMS refers to the answers to items 1-3 where 6 = most bothersome and 0 = least bothersome). (Maximum bothersomeness = 18; No bothersomeness = 0)
The Hot Flash Related Daily Interference Scale (HFRDIS) measures (as a score of 0 to 10) the effect of hot flashes on overall quality of life and on nine specific activities: work, social activities, leisure activities, sleep, mood, concentration, relations with others, sexuality, and enjoyment of life. The 10 answers are added up to get a total score. HFRDIS Score (Maximum Bothersomness = 100; No Bothersomeness = 0). The higher the score, the more bothersome the symptoms.
The Insomnia Severity Index has seven questions. For each question, most bothersome = 4; not bothersome = 0. The seven answers are added up to get a total score. Total score categories: 0-7 = No clinically significant insomnia; 8-14 = Subthreshold insomnia; 15-21 = Clinical insomnia (moderate severity); 22-28 = Clinical insomnia (severe)
Fatigue Severity Scale (FSS) of Sleep Disorders. The Fatigue Severity Scale (FSS) is a method of evaluating the impact of fatigue. The FSS is a short questionnaire (10 questions) that requires the subject to rate level of fatigue. The FSS questionnaire contains nine statements that rate the severity of fatigue symptoms. Each statement is read and the corresponding number from 1 to 7 is circled. A low value (e.g., 1) indicates strong disagreement with the statement, whereas a high value (e.g., 7) indicates strong agreement. (Maximum bother = 70; No bother = 0)
