- Brief Summary
This is a proof-of-concept phase 2 clinical trial to investigate the effect of the phytoestrogenic supplement PhytoSERM on vasomotor symptoms and other symptoms associated with the menopausal transition, and on blood-based biomarkers in peri- and postmenopausal women.
After the screening period, participants will be randomized to PhytoSERM 50 mg pills (administered orally, once per day) or matching placebo, 1:1 allocation, for a period of 12 weeks. After 12 weeks, all participants in the placebo group will be crossed-over to receive PhytoSERM pills for the remainder of the study (open-label phase).
- Detailed Description
This is a double-blinded, randomized, placebo-controlled, parallel designed, proof-of-concept phase 2 clinical trial to determine effect of PhytoSERM on vasomotor symptoms and other symptoms associated with the menopausal transition. PhytoSERM or placebo pills will be administered orally once a day over 24 weeks. Safety and tolerability will also be assessed over the duration of the study.
A total of 132 peri- or postmenopausal women aged 45-60 years and who are experiencing hot flashes will be enrolled in this trial. To determine eligibility, all participants will undergo cognitive assessment, physical assessment, ECG, clinical/safety laboratory assessment, and interviews. After a 2-week screening period, participants will be randomized to study intervention (PhytoSERM 50mg administered orally, once per day) or matching placebo, in a 1:1 allocation. After 12 weeks, participants in the placebo group will be crossed-over to PhytoSERM 50 mg for the remaining 12 weeks (open-label extension period). Hot flashes will be measured both objectively and subjectively. Objective data will be skin conductance levels collected via a wearable device that enables real-time physiological data acquisition, including activity and sleep data. Study participants will be asked to complete a total of 8 study visits. Study visits will occur at 4-week intervals after the baseline, except for visits # 6 and 7 (open-label period) which will occur at 6-week intervals after visit # 5 (final outcomes assessments visit). Visits 1, 2, 5 and 7 will last approximately 2-4 hours; visits 3, 4, 6 and 8 will last approximately 45 minutes.
All participants will be enrolled at a single site, at the University of Arizona (UA) Clinical \& Translational Sciences Research Center (CATS).

- Primary Outcome Measures
Name Time Method Hot Flash Composite score Daily from baseline to week 24 Composite score comprised by hot flash frequency and severity (sum of weekly hot flashes weighted by severity: mild, moderate, severe). Higher score indicates a bad outcome. No minimum or maximum values.
- Secondary Outcome Measures
Name Time Method Trail Making Test score Baseline, week 4, 8, 12 and 24. Test that involves visual scanning and working memory. Score is the amount of seconds taken to complete the test; the greater the time the worse the score.
NIH Toolbox List Sorting Working Memory Test score Baseline, week 4, 8, 12 and 24. An assessment of working memory administered on an iPad. Scores range from 0 to 26, with higher being better.
NIH Toolbox Picture Sequence Memory Test Baseline, week 4, 8, 12 and 24. An assessment of episodic memory administered on an iPad. The participants are asked to recall the sequence of pictures demonstrated over two learning trials; sequence length varies from 6-18 pictures. Participants are given credit for each adjacent pair of pictures they correctly place up to the maximum value for the sequence, which is one less than the sequence length. Range is 0-17.
NIH Toolbox Auditory Verbal Learning Test Baseline, week 4, 8, 12 and 24. An assessment of immediate memory and verbal learning administered on an iPad.Possible range is 0-45 words, with higher scores representing better performance.
NIH Toolbox Oral Symbol Digit Test Baseline, week 4, 8, 12 and 24. An assessment of processing speed administered on an iPad. Scored as the number of items answered correctly in 120 seconds (possible range is 0-144).
Bone Mineral Content (BMC) Baseline, week 12 and 24 BMC in grams will be measured with a Dual-energy X-ray absorptiometry (DXA) scan. Expected range is 2,000 - 3,500 g, with higher being better.
Pittsburgh Sleep Quality Index (PSQI) Baseline, week 4, 8, 12, 18, 24 and 28. Instrument used to measure the quality patterns of sleep in the older adult. A global sum of "5" or greater indicates a "poor" sleeper.
Bone Mineral Density (BMD) Baseline, week 12 and 24 BMD in g/cm2 will be measured with a Dual-energy X-ray absorptiometry (DXA) scan. Expected range is 0.5-1.5 g/cm2, with higher being better.
Menopause Rating Scale score At screening, weeks 12, 24 and 28. A a health-related quality of life scale measuring the impact of menopausal symptoms. The total score of the MRS ranges between 0 (asymptomatic) and 44 (highest degree of complaints).
Body Mass Index (BMI) Baseline, week 12 and 24 BMI will be measured with a Dual-energy X-ray absorptiometry (DXA) scan. Range is 10-45.
