The purpose of this study is to test whether a oral micronized progesterone reduces the Vasomotor Symptom Score comprised of the number and severity of hot flushes and night sweats in perimenopausal women. Oral micronized progesterone is molecularly identical to human progesterone, a steroid hormone. It is sold by prescription for use to prevent endometrial cancer in women taking estrogen in menopause. This research study will test whether progesterone reduces perimenopausal hot flushes and night sweats. It will also test whether progesterone improves sleep disturbances and anxiety.
This is a randomized, double-blind placebo-controlled trial of oral micronized progesterone (300 mg daily at bedtime) for perimenopausal women living anywhere in Canada. Using the self-reported maximum menstrual cycle length in the previous year, women will be stratified as in Early Perimenopause (\<60 days) or Late Perimenopause (\>=60 days). The design includes a 28-day baseline run-in followed by 12 weeks of randomized therapy.

Vasomotor Symptoms (VMS)/ VMS Score - at 12 Weeks
Participants will complete a daily calendar (Daily Perimenopause Hot Flush Calendar) to record frequency (actual number) and severity (quantified by ordinal scale ie 0=none to 4=extreme) of hot flushes and night sweats. The VMS Score will be calculated as follows: Daily VMS Score = (# night sweats) x (severity) + (#hot flushes) x (severity). Outcome is the average daily VMS Score during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate.
Time frame: 12 weeks
Frequency of VMS
Frequency (count) of hot flushes/hot flashes and night sweats per day from prospective daily calendar records. Outcome is the average daily VMS Frequency (day + night) during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate.
Time frame: 12 weeks
Severity of VMS
Severity (0-4, 0=no intensity, 4=extreme intensity) of hot flushes/hot flashes and night sweats per day from prospective daily calendar records. Daily summary score is the maximum of daytime and nighttime severity. Outcome is the average daily severity during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate.
Time frame: 12 weeks
VMS Score by Early Perimenopause
subgroup analysis of VMS Score by Early Perimenopause (no skipped period or \<60 day cycle length). Outcome is the average daily VMS Score during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate. Participants will complete a daily calendar (Daily Perimenopause Hot Flush Calendar) to record frequency (actual number) and severity (quantified by ordinal scale ie 0=none to 4=extreme) of hot flushes and night sweats. The VMS Score will be calculated as follows: Daily VMS Score = (# night sweats) x (severity) + (#hot flushes) x (severity).
Time frame: 12 weeks
VMS Score by Late Perimenopause
subgroup analysis of VMS Score by Late Perimenopause (those with skipped or ≥60 day cycle lengths). Outcome is the average daily VMS Score during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate. Participants will complete a daily calendar (Daily Perimenopause Hot Flush Calendar) to record frequency (actual number) and severity (quantified by ordinal scale ie 0=none to 4=extreme) of hot flushes and night sweats. The VMS Score will be calculated as follows: Daily VMS Score = (# night sweats) x (severity) + (#hot flushes) x (severity).

Subgroup Analysis for Those With Frequent and Severe VMS - VMS Score
VMS Score for those with more frequent (≥7 per day and moderate to severe episodes of intensity 2-4) at baseline. Participants will complete a daily calendar (Daily Perimenopause Hot Flush Calendar) to record frequency (actual number) and severity (quantified by ordinal scale ie 0=none to 4=extreme) of hot flushes and night sweats. The VMS Score will be calculated as follows: Daily VMS Score = (# night sweats) x (severity) + (#hot flushes) x (severity).
Time frame: 12 weeks

Time frame: 12 weeks
Anxiety
Daily average rating of anxiety (0-4) from prospective daily calendar records. Outcome is the average daily rating during the final 28 days of therapy, to be analysed with 28-day run-in scores as covariate. Scale name: Anxiety (4=Worst, 0=None)
