Abstract
PURPOSE Vasomotor symptoms (VMS) are common among individuals with breast cancer (BC) and poorly managed symptoms are associated with reduced quality of life, treatment discontinuation, and poorer breast cancer outcomes. Direct comparisons among therapies are limited, as prior studies evaluating VMS interventions have utilized heterogeneous change measures which may not fully assess the perceived impact of change in VMS severity. METHODS We performed a prospective study where BC patients chose one of four categories of interventions to manage VMS. Change in VMS severity at 6 weeks was assessed using the validated Hot Flush Rating Scale (HFRS). A novel weighted change score integrating baseline symptom severity and directionality of change was computed to maximize the correlation between the change score and a perceived treatment effectiveness score. Variables influencing change in VMS severity were included in a regression tree to model factors influencing the weighted change score. RESULTS 100 baseline and follow-up questionnaires assessing VMS were completed by 88 patients. Correlations between treatment effectiveness and VMS outcomes strengthened following adjustment for baseline symptoms. Patients with low VMS severity at baseline did not perceive change in treatment effectiveness. Intervention category was predictive of change in HFRS at 6 weeks. CONCLUSION Baseline symptom severity and the directionality of change (improvement or deterioration of symptoms) influenced the perception of clinically meaningful change in VMS severity. Future interventional studies utilizing the weighted change score should target moderate-high baseline severity patients.

Abstract
OBJECTIVES The aims of the study were to further characterize the efficacy of fezolinetant for the treatment of moderate-to-severe vasomotor symptoms (VMS) due to menopause using responder analysis and to investigate whether efficacy, not adjusted for placebo, resulted in clinically meaningful within-patient change. METHODS This prespecified analysis used pooled data from two phase 3, randomized, double-blind, placebo-controlled studies (SKYLIGHT 1 and 2). Responders were those experiencing ≥50%, ≥75%, ≥90%, or 100% reduction in VMS frequency from baseline to weeks 4 and 12. Responder analysis was performed for patient-reported outcome (PRO) measures to evaluate participants achieving a clinically meaningful within-patient change (not placebo adjusted) at week 4 and 12 versus baseline. Single responders were based on outcomes of VMS frequency, Patient-Reported Outcomes Measurement Information System Sleep Disturbance-Short Form 8b Total Score, Menopause-Specific Quality of Life (MENQoL) Total Score, and MENQoL VMS Domain Score. Double and triple responder analyses combined VMS frequency plus one or more of the PRO. Patient Global Impression of Change VMS was deemed a suitable anchor measure for meaningful within-patient change in VMS frequency. RESULTS A greater proportion of fezolinetant-treated versus placebo-treated participants had ≥50%, ≥75%, ≥90%, or 100% reduction in VMS frequency from baseline to weeks 4 and 12. A greater proportion of responders were observed in the fezolinetant groups versus placebo at week 12 in all four single responder analyses. In the double and triple responder analyses, odds ratios were supportive of a beneficial effect for both doses of fezolinetant versus placebo. CONCLUSIONS Fezolinetant was associated with significantly higher within-patient clinically meaningful improvement in important PRO, including VMS frequency, PROMIS SD SF 8b Total Score, MENQoL Total Score, and MENQoL VMS Domain Score.

Abstract
OBJECTIVE To evaluate the efficacy and safety of fezolinetant for moderate to severe vasomotor symptoms (VMS) associated with menopause in East Asian women. METHODS In this phase 3, randomized, double-blind study, postmenopausal women with moderate to severe VMS (minimum average frequency in the 10 days before randomization, ≥7/day or 50/week) received fezolinetant 30 mg/day or placebo (weeks 1-12), followed by an open-label extension phase with fezolinetant 30 mg/day (weeks 13-24). The co-primary endpoints were the mean changes in the daily frequency and severity of VMS at weeks 4 and 12. RESULTS Among 301 participants, the difference in the least squares mean change (95% confidence interval) from baseline in the daily frequency of moderate to severe VMS versus placebo was -0.65 (-1.41 to 0.12) at week 4 and -0.55 (-1.35 to 0.26) at week 12. The differences in the least squares mean change from baseline in the VMS severity score versus placebo were -0.06 (-0.14 to 0.03) and -0.13 (-0.27 to 0.01) at weeks 4 and 12, respectively. Serious adverse events occurred in 0.7% of participants receiving fezolinetant in weeks 1 to 12, compared with 1.3% of those receiving placebo. CONCLUSIONS Fezolinetant was generally safe but did not reduce the frequency or severity of VMS versus placebo in postmenopausal women in this study.ClinicalTrials.Gov Identifier: NCT04234204.

Abstract
PURPOSE OF REVIEW Given the potential for exogenous hormones to influence risk and course of MS, this narrative review aims to summarize current knowledge from observational and interventional studies of exogenous hormones in humans with MS. RECENT FINDINGS Large randomized clinical trials for combined oral contraceptives and estriol both show modest effect on inflammatory activity, with the latter showing potential neuroprotective effect. After fertility treatment, large actively treated cohorts have not confirmed any elevated risk of relapse. Preclinical data suggest that androgens, selective estrogen receptor modulators (SERMs), and selective androgen receptor modulators (SARMs) may be neuroprotective but clinical data are lacking. Gender affirming treatment, particularly estrogen in trans-women, could possibly be associated with elevated risk of inflammation. For women with MS entering menopause, hormone therapy appears safe during the appropriate menopausal window, but its long-term effects on neuroprotection are unknown. Exogenous hormones, used in varied doses and for diverse indications, have variable effects on MS risk, inflammatory activity, and neuroprotection. Large randomized trials are needed before it is possible to determine the true effect of exogenous hormones in a condition as complex as MS.

Abstract
CONTEXT Vasomotor symptoms (VMS) are common, bothersome, and can persist for years before and after menopause. OBJECTIVE We aimed to assess efficacy/safety of fezolinetant for treatment of moderate to severe VMS associated with menopause. METHODS In this double-blind, placebo-controlled, 12-week phase 3 trial with a 40-week active treatment extension (NCT04003142; SKYLIGHT 2), women aged 40 to 65 years with minimum average 7 moderate to severe VMS/day were randomized to 12 weeks of once-daily placebo, fezolinetant 30 mg, or fezolinetant 45 mg. Completers were rerandomized to fezolinetant 30/45 mg for 40 additional weeks. Coprimary efficacy endpoints were mean daily change from baseline to week 4 (W4) and W12 in VMS frequency and severity. Safety was also assessed. RESULTS Both fezolinetant doses statistically significantly reduced VMS frequency/severity at W4 and W12 vs placebo. For VMS frequency, W4 least squares mean (SE) reduction vs placebo: fezolinetant 30 mg, -1.82 (0.46; P < .001); 45 mg, -2.55 (0.46; P < .001); W12: 30 mg, -1.86 (0.55; P < .001); 45 mg, -2.53 (0.55; P < .001). For VMS severity, W4: 30 mg, -0.15 (0.06; P < .05); 45 mg, -0.29 (0.06; P < .001); W12: 30 mg, -0.16 (0.08; P < .05); 45 mg, -0.29 (0.08; P < .001). Improvement in VMS frequency and severity was observed by W1 and maintained through W52. Serious treatment-emergent adverse events were infrequent, reported by 2%, 1%, and 0% of those receiving fezolinetant 30 mg, fezolinetant 45 mg, and placebo, respectively. CONCLUSION Daily fezolinetant 30 and 45 mg were efficacious and well tolerated for treating moderate to severe VMS associated with menopause.

"Let's see what happens:"-Women's experiences of open-label placebo treatment for menopausal hot flushes in a randomized controlled trial. PLoS One 2022; 17:e0276499.

Abstract
Open-label (honestly prescribed) placebos are an ethical way to evoke placebo effects in patients. As part of a mixed-methods study, we conducted in-depth interviews with eight menopausal women who underwent and benefitted from open-label placebo treatment in a randomized-controlled trial of hot flushes. Data were analyzed using Interpretative Phenomenological Analysis. We found that the women had low expectations about the placebo treatment yet endorsed what they referred to as “hope” and openness to “see what happens”. Recording hot flushes via the symptom diary was viewed as a valuable opportunity for self-examination and appraising outcomes. Receiving relief from the placebo treatment empowered women and enhanced their sense of control and agency. In summary, participants’ initial openness towards placebos, their hopes to get better, monitoring symptoms closely, and taking the initiative to address symptoms were components of a positive open-label placebo experience.

Abstract
BACKGROUND Depression, sleep disturbances, and cognitive difficulties impair the quality of life in people with multiple sclerosis (MS). Similar symptoms are also frequent during the menopausal transition. In clinical practice, it is important to consider the multifactorial causes of these overlapping symptoms and the potential benefits of menopausal hormone therapy (MHT). The objective of this study was to evaluate vasomotor symptoms (VMS), mood, sleep, and cognition of menopausal women with and without MS at baseline and during one year of MHT. METHODS In this prospective baseline-controlled study, peri- and early postmenopausal participants with (n=14) and without (n=13) MS received MHT containing 1 or 2 mg of estradiol and cyclical 10 mg dydrogesterone for one year. VMS frequency, depressive symptoms (measured by Beck Depression Inventory), insomnia severity (Insomnia Severity Index), and cognitive performance (Paced Auditory Serial Addition Test; PASAT, Symbol Digit Modalities Test; SDMT) were evaluated at baseline and at 3 and 12 months of treatment. Differences in the outcome measures between groups at baseline were assessed using the Mann-Whitney U test. Changes during follow-up compared to baseline within groups were evaluated by Wilcoxon Signed Ranks Test. P < 0.05 was considered for statistical significance. MS activity was monitored by clinical assessment and brain MRI at baseline and at 12 months. RESULTS Depressive symptoms were more common in MS group, while vasomotor and insomnia symptoms were equally common. During follow-up with MHT, VMS frequency decreased in both groups. Depressive symptoms decreased at 3 months (p = 0.031 with MS; p = 0.024 without MS) and the reduction was sustained at 12 months (p = 0.017; p = 0.042, respectively). Alleviation in insomnia symptoms was seen in participants without MS at 3 months (p = 0.029) and in those participants with MS suffering insomnia at baseline (p = 0.016 at 3 months; p = 0.047 at 12 months). Both groups improved their performance in PASAT, but no significant change was observed in SDMT. MS activity at baseline was mainly stable, and no increase in activity was detected during MHT. CONCLUSION Improvements in vasomotor, depressive, and insomnia symptoms observed during one year of MHT are encouraging and suggest that larger placebo-controlled studies of MHT in women with MS are warranted. Cognitive implications were inconclusive because the findings in PASAT likely result from practice effect. MHT did not show any adverse effect on MS activity and increasing safety data will hopefully facilitate patient recruitment for future studies.

Abstract
Abstract
Study Objectives
The neuropeptide orexin promotes wakefulness, modulates thermoregulation, increases after menopause, and is normalized in women receiving estrogen therapy, suggesting a role for orexin antagonism as a treatment for the vasomotor symptom (VMS)-associated insomnia disorder. We tested the efficacy of the dual orexin receptor antagonist suvorexant for chronic insomnia related to nighttime VMS.
Methods
In a double-blind, placebo-controlled trial, 56 women with chronic insomnia associated with nighttime VMS, Insomnia Severity Index (ISI) scores ≥15, and >30 min of diary-rated wake after sleep-onset (WASO) were randomized to receive oral suvorexant 10–20 mg (n = 27) or placebo (n = 29) nightly for 4 weeks. Analysis of within-person change in ISI was adjusted for baseline ISI and race.
Results
Mean baseline ISI scores were 18.1 (95% CI, 16.8 to 19.4) and 18.3 (95% CI, 17.2 to 19.5) in the suvorexant and placebo groups, respectively (p = .81). The average 4-week ISI within-person decrease from baseline was greater on suvorexant (−8.1 [95% CI, −10.2 to −6.0]) compared to placebo (−5.6 [95% CI, −7.4 to −3.9], p = .04). Compared to placebo, nighttime diary-rated VMS frequency was significantly reduced with suvorexant (p < .01). While diary-rated WASO and total sleep time trended toward improvement on suvorexant, findings were not significant after adjustment for multiple comparisons. Daytime VMS and other sleep-related outcomes did not differ between groups. Suvorexant was well tolerated.
Conclusion
These results suggest that suvorexant is likely a well-tolerated and efficacious treatment for VMS-associated insomnia disorder and reduces nighttime VMS. Antagonism of orexin receptors could provide a novel therapeutic option for midlife women with VMS-associated chronic insomnia.

Abstract
Background The efficacy of flibanserin in treating hypoactive sexual desire disorder (HSDD) is based upon statistically significant improvements in sexual desire, satisfying sexual events, and distress. However, clinically meaningful benefit has not been well characterized. Aim Evaluate clinically meaningful benefit of flibanserin. Methods Data were pooled from 3 pivotal trials evaluating flibanserin 100 mg qhs in premenopausal women (flibanserin, n = 1192; placebo, n = 1215). Flibanserin trial data in postmenopausal women (flibanserin, n = 450; placebo, n = 476) were analyzed separately. Clinically meaningful benefit was evaluated by the Patient Global Impression of Improvement (PGI-I). Responders were determined through anchor-based analyses that used the PGI-I for key efficacy endpoints: satisfying sexual events (SSE), desire domain of the Female Sexual Function Index (FSFI-d), and distress associated with decreased sexual desire (FSDS-R13). Odds ratios were calculated to assess effect size and Kaplan-Meier analyses were performed to estimate onset time for treatment benefit. Outcomes PGI-I, anchor-based analyses for key efficacy endpoints (SSE, FSFI-d, FSDS-R13), odds ratios, onset time for treatment benefit. Results Based on the PGI-I, more patients reported clinically meaningful benefit with flibanserin treatment versus placebo (49.8% vs 33.6%, premenopausal cohort; 40.5% vs 28.7%, postmenopausal cohort). In anchor-based analyses, responder rates were significantly higher for premenopausal women on flibanserin (46.1%–55.2%) than placebo (34.1%–44.2%) for all 3 key efficacy endpoints (P < .0001). Responder rates for postmenopausal women on flibanserin were higher compared to placebo for SSE (29.8% vs 22.9%; P = .015) and FSFI-d (38.9% vs 26.3%; P = .0001). Odds ratios for key endpoints indicated that premenopausal women were 2.0–2.4 times as likely to be responders with flibanserin treatment compared to placebo. Postmenopausal women were 1.6 times as likely to be responders with flibanserin for FSFI-d. Kaplan-Meier analyses indicated significant separation between flibanserin and placebo for the key endpoints in both premenopausal and postmenopausal cohorts (log-rank tests P < .01) with earlier median response times among patients receiving flibanserin. Clinical Implications Patient-reported benefit assessments such as the PGI-I capture the patient's perspective and may be a useful approach in assessing overall clinical meaningfulness for sexual dysfunction therapies. Strengths and Limitations Strengths include a well-powered study with large enrollment, use of validated instruments, and self-assessment of treatment benefit. Limitations include pooling of trial data in premenopausal women with slightly different study designs and use of an endpoint (SSE) indirectly related to HSDD. Conclusion Assessment of clinically meaningful benefit and additional responder analyses provide further support for flibanserin's efficacy beyond numerical improvements in endpoint measures.

Abstract
IMPORTANCE High placebo response can often mask the evaluation of active treatment in clinical studies for women with hot flashes and potentially undermine the evaluation of new treatments. OBJECTIVE The aim of this meta-analysis was to determine the factors associated with high placebo response (defined as the reduction in the mean number of hot flash frequency from baseline) in randomized, controlled, double-blind studies enrolling women with hot flashes. EVIDENCE REVIEW To identify eligible studies, Embase, MEDLINE, and BIOSIS Previews were searched for English-language articles published between April 1975 and August 2020. Placebo-controlled, double-blind, randomized studies that assessed changes in hot flash frequency were included if they satisfied the defined criteria. We conducted univariate and multivariate analyses using categorical and numerical data. Categorical data included the following variables and levels in brackets: active treatment type (hormone therapy /non- hormone therapy /complementary and alternative medicine), administration route (oral/non-oral), study region (in/excluded the US), breast cancer population (in/excluded), entry criteria of hot flash severity (moderate to severe only/all included), parallel or crossover study, placebo run-in period before treatment (yes/no), and menopausal status (postmenopausal only/include perimenopausal/include premenopausal). Numerical data included published year, pretreatment period duration, treatment period duration, number of sites, number of total participants, number of placebo participants, number of treatment arms, mean age, BMI, and hot flash frequency at baseline. FINDINGS Forty-three of the 802 identified publications were included in the review. Multivariate analysis identified three individual factors associated with high placebo response: treatment period duration, number of treatment arms, and BMI. CONCLUSIONS AND RELEVANCE We identified several factors associated with high placebo response in clinical studies of women with hot flashes. Knowing these factors may enable proactive implementation of operational and analytic strategies that further aid in determining the true treatment effect of an intervention.

Neurokinin 3 Receptor Antagonists Compared With Serotonin Norepinephrine Reuptake Inhibitors for Non-Hormonal Treatment of Menopausal Hot Flushes: A Systematic Qualitative Review. Adv Ther 2021; 38:5025-5045. [PMID: 34514552 PMCID: PMC8478773 DOI: 10.1007/s12325-021-01900-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 08/19/2021] [Indexed: 11/30/2022]
Abstract
Introduction Hot flushes/flashes (HFs) or other vasomotor symptoms affect between 45 and 97% of women during menopause. Hormone replacement therapy (HRT) is effective at alleviating menopausal symptoms, but some women cannot or prefer not to take HRT. Since current non-hormonal options have suboptimal efficacy/tolerability, there is a pressing need for an effective, well-tolerated alternative. The neurokinin 3 receptor (NK3R) has recently been implicated in the generation of menopausal HFs and represents a novel therapeutic target to ameliorate HF symptoms. This review aims to assess if NK3R antagonists (NK3Ras) are more effective than Serotonin Norepinephrine Reuptake Inhibitors (SNRIs)—currently a common choice for non-hormonal treatment of menopausal HFs. Methods Studies were identified after systematically searching Ovid MEDLINE and EMBASE databases based on PRISMA guidelines. Trial quality and bias were assessed. Key efficacy outcomes (HF frequency, HF severity and number of night-time awakenings/night-sweats) and selected safety outcomes were extracted and analysed. Results Seven SNRI and four NK3Ra placebo-controlled randomised trials (plus four follow-up reports) were included in this review. NK3Ra administration resulted in a larger reduction from baseline in HF frequency, HF severity and night-sweats compared to SNRIs. Five of seven SNRI trials showed a reduction in HF frequency that was statistically significant (by 48–67% from baseline at weeks 8 or 12) whereas all NK3Ra trials showed a statistically significant reduction in HF frequency (by 62–93% from baseline at weeks 2, 4 or 12). While SNRI trials reported poor tolerability, particularly nausea, NK3Ra trials reported good tolerability overall, although two trials reported elevation in transaminases. Conclusion NK3Ras trials show encouraging efficacy and tolerability/safety. Completion of phase 3 NK3Ra trials are required to confirm efficacy and uphold safety/tolerability data but phase 2 results suggest that NK3Ras are more effective than SNRIs for non-hormonal treatment of menopausal HFs.

Abstract
Objective: The aim of this study was to select the minimum effective dose of estetrol (E4) for the treatment of vasomotor symptoms in postmenopausal women. Methods: This was a multicenter, randomized, double-blind, placebo-controlled study. Postmenopausal women (n = 257, of whom 32 were hysterectomized) aged 40 to 65 years, with ≥7 moderate to severe hot flushes (HFs) per day, or 50 or more moderate to severe HFs weekly, received 2.5, 5, 10, or 15 mg E4, or placebo once-daily for a period of 12 weeks. Efficacy was assessed by recording the frequency and severity of HFs. Overall safety was assessed by recording adverse events, measuring endometrial thickness, and monitoring bleeding patterns. Treatment groups were compared using analysis of covariance. Results: The frequency of moderate to severe HFs decreased with all E4 doses. The difference in the percentage change of weekly HF frequency was significant for 15 mg E4 versus placebo at both W4 (−66% vs −49%, P = 0.032) and W12 (−82% vs −65%, P = 0.022). The decrease in severity of HFs was significantly more pronounced for 15 mg E4 than for placebo at both W4 (−0.59 vs −0.33, P = 0.049) and W12 (−1.04 vs −0.66, P = 0.049); the other doses failed to achieve statistical significance. In nonhysterectomized women, endometrial thickness increased during treatment and normalized following progestin treatment at study completion. No endometrial hyperplasia was observed. Conclusions: Estetrol 15 mg is considered to be the minimum effective daily oral dose for treatment of vasomotor symptoms. Its current seemingly favorable safety profile is further to be confirmed in phase 3 clinical development. Video Summary:.

Abstract
Objective: In the primary analysis of the phase 2b VESTA study, oral fezolinetant reduced frequency and severity of menopausal vasomotor symptoms (VMS) compared with placebo. This secondary analysis evaluates effects of fezolinetant on responder rates and patient-reported outcomes (PROs). Methods: In this 12-week, double-blind study, postmenopausal women with moderate/severe VMS were randomized to fezolinetant 15, 30, 60, or 90 mg BID or 30, 60, or 120 mg QD or placebo. Proportion of responders was based on reductions in VMS from daily diary records. P values for comparisons between active treatment and placebo were calculated using logistic regression. Changes from baseline in PROs (Menopause-Specific Quality of Life questionnaire, Hot Flash-Related Daily Interference Scale, Greene Climacteric Scale) were conducted using a mixed model for repeated measurements and compared post hoc with published minimally important differences (MIDs). Results: Of 356 women randomized, 352 were treated and analyzed. A greater proportion of women receiving fezolinetant versus placebo met definitions of response at week 12. For all doses, mean changes from baseline in Menopause-Specific Quality of Life questionnaire VMS scores exceeded the MID (1.2) at weeks 4 (placebo: −1.8; fezolinetant: range, −1.9 to −3.6) and 12 (placebo: −2.3; fezolinetant: range, −2.9 to −4.4). Mean changes in Hot Flash-Related Daily Interference Scale at weeks 4 (placebo: −2.2; fezolinetant: range, −2.5 to −3.8) and 12 (placebo: −2.9; fezolinetant: range, −3.3 to −4.3) exceeded the MID (1.76). Greene Climacteric Scale-VMS domain scores improved for most fezolinetant doses versus placebo (week 4, placebo: −1.7; fezolinetant: range, −2.1 to −3.3; week 12, placebo: −2.1; fezolinetant: range, −2.7 to −3.6). Conclusions: Oral fezolinetant was associated with higher responder rates than placebo and larger improvements in QoL and other PRO measures, including a reduction in VMS-related interference with daily life.

Abstract
One of the major symptoms of climacteric syndrome is hot flushes (HF). They are most often experienced as very disabling. Estrogen therapy is the most effective treatment. However, it may be contraindicated in some women. The aim of this article is to provide a review of the scientific literature on pharmacological and non-pharmacological alternatives in this context. Only randomized trials and meta-analyses of randomized trials were considered. This review shows that some treatments usually used in non-gynecological or endocrinological disease have significant effect in reducing the frequency and/or severity of HF. Hence, some selective serotonin reuptake inhibitors (paroxetine, citalopram and escitalopram), serotonin and norepinephrine reuptake inhibitors (venlafaxine, desvenlafaxine) gabapentin, pregabalin and clonidine have a statistically effect as compared with placebo in reducing, the frequency and/or severity of HF. Some phytoestrogens, such as genistein, may also reduce the frequency of HF. Regarding non-pharmacological interventions, hypnosis, acupuncture or yoga have been analyzed with significant beneficial results, even if their evaluation is difficult by the absence of a good placebo group in most trials. By contrast, other approaches, both pharmacological or non-pharmacological, appear to be ineffective in the management of HT. These include homeopathy, vitamin E, alanine, omega 3, numerous phytoestrogens (red clover, black cohosh…), primrose oil, physical activity. In women suffering from breast cancer, several additional problems are added. On the one hand because all phytoestrogens are contraindicated and on the other hand, in patients using tamoxifen, because the molecules, that interact with CYP2D6, are to be formally avoided because of potential interaction with this anti-estrogen treatment. In conclusion, several pharmacological and non-pharmacological alternatives have significant efficacy in the management of severe HF.

Abstract
OBJECTIVE The Menopause Strategies: Finding Lasting Answers for Symptoms and Health clinical trials network was funded by the National Institutes of Health to find new ways to alleviate the most common, bothersome menopausal symptoms by designing and conducting multiple concurrent clinical intervention studies, accommodating a wide scope of populations and intervention strategies. METHODS Trials were conducted in Boston, Indianapolis, Minneapolis, Oakland, Philadelphia, and Seattle, with the Data Coordinating Center in Seattle, and were designed with standardized eligibility criteria and endpoints. Primary outcomes focused on vasomotor symptoms, sleep quality and insomnia symptoms, and vaginal symptoms. Secondary outcomes included quality of life, sexual function, and mood. RESULTS We completed five randomized clinical trials and three ancillary studies, testing nine interventions in over 1,300 women and collecting nearly 16,000 bio-specimens. Escitalopram, venlafaxine hydrochloride extended release, and low-dose estradiol diminished hot flashes by approximately 50% as compared with a 30% decrease by placebo. No benefits on vasomotor symptoms were observed with yoga or exercise compared with usual activity, nor with omega-3 supplementation compared with placebo. Cognitive behavioral therapy for insomnia reduced self-reported insomnia symptoms and improved overall sleep quality compared with menopause education control. We did not find significant benefit from a vaginal estradiol tablet or a vaginal moisturizer compared with placebo tablet and gel in diminishing the severity of vaginal symptoms. CONCLUSIONS The MsFLASH trials contributed substantially to our understanding of bothersome menopausal symptom treatment. It is important that clinicians counseling women about available treatment options consider all therapies-both nonhormonal and hormonal.

Abstract
This study investigated the efficacy of an open-label placebo (OLP) treatment for menopausal hot flushes. Women with at least five moderate or severe hot flushes per day were allocated to receive four weeks of OLP for twice a day or no-treatment. Intention-to-treat analyses included n = 100 women. In comparison to no-treatment, OLP reduced the log-transformed hot flush composite score (frequency × intensity) (mean difference in change: − 0.32, 95% CI [− 0.43; − 0.21], p < 0.001, Cohen’s d = 0.86), hot flush frequency (− 1.12 [− 1.81; − 0.43], p = 0.02, Cohen’s d = 0.51), and improved overall menopause-related quality of life (− 2.53 [− 4.17; − 0.89], p = 0.02, Cohen’s d = 0.49). Twelve (24%) (vs. three [6%]) patients had 50% lesser hot flushes. Problem rating of hot flushes and subdomains of quality of life did not improve. After four weeks, the OLP group was further divided via randomization to continue or discontinue the treatment. Benefits were maintained at week 8 (log-transformed score: − 0.04 [− 0.06; 0.14], p = 0.45). There was no difference between taking placebos for 8 or 4 weeks (log-transformed score: 0.04 [− 0.17; 0.25], p = 0.73). Results indicate that open-label placebos may be an effective, safe alternative for menopausal hot flushes.

Abstract
Background Interest in herbal medicines and non-hormonal therapies for the treatment of menopausal symptoms has increased since the publication of adverse effects of estrogen replacement therapy. Vasomotor symptoms are the most characteristic and notable symptoms of menopause. Objective To investigate the changes in the frequency and severity of hot flush and associated vasomotor symptoms experienced by peri-menopausal and menopausal women supplemented with the herbal formulation (Nu-femme™) comprising Labisia pumila (SLP+®) and Eurycoma longifolia (Physta®) or placebo. Design Randomised, double-blind, placebo-controlled, 24-week study enrolled 119 healthy women aged 41–55 years experiencing peri-menopausal or menopausal symptoms and supplemented with Nu-femme™ or placebo. The primary endpoint was comparative changes between treatment groups in the change in the frequency and severity of hot flushes. The secondary objectives were to assess the changes in the frequency and severity of joint pain, Menopause Rating Scale (MRS) and Menopause-Specific Quality of Life (MENQOL) questionnaire domain scores. Concentrations of serum hormone, lipid profile, bone markers, sleep quality and vitality were also studied as secondary objectives. Results At week 12, significant (P < 0.01) improvements in hot flush symptoms were observed in Nu-femme™ and placebo groups. Even though there was no significant difference between groups, higher percentage of improvement, 65%, was seen in Nu-femme™ compared to 60% in placebo. Significant improvements (P < 0.001) in MRS and MENQOL scores at weeks 12 and 24 were observed in both groups, respectively. Luteinising hormone and follicle-stimulating hormone levels were significantly reduced (P < 0.05) at weeks 12 and 24, respectively, compared to baseline in the Nu-femme™ group, with no significant changes observed in the placebo group. There were significant (P < 0.05) reductions in serum low-density lipid and triglycerides levels at week 12 in Nu-femme™ group, but no changes seen in placebo group. At the end of week 24, changes in haematology and clinical chemistry parameters remained within normal clinical ranges in both groups. Conclusion Herbal formulation consists of L. pumila and E. longifolia (Nu-femme™) may support reduction in hot flushes and improvements in hormone and lipid profile in healthy peri-menopausal and menopausal women.

Abstract
OBJECTIVE Because hot flashes are a common symptom experienced by women with breast cancer, we sought to explore genetic predictors associated with response to acupuncture for the treatment of hot flashes. METHODS Using data from our completed randomized controlled trial (Clinicaltrials.gov identifier: NCT01005108) on hot flashes among breast cancer survivors who provided biomarker collection (N = 108), we extracted and assayed DNA for single nucleotide polymorphisms in genes involved in neurotransmission, thermoregulation, and inflammation (ADORA1, COMT, TCL1A, and TRPV1). For our primary outcome we classified individuals with a 50% or more reduction in their hot flash composite score at the end of treatment as responders. We used Fisher exact test to identify individual and combined single nucleotide polymorphisms associated with treatment response. RESULTS Among women (N = 57) who received acupuncture treatment (electro or sham), we found that women who were carriers of at least one of these six genotypes (ADORA1 rs41264025-GA or rs16851029-GG or rs12744240-GT, COMT rs6269-GA, TCL1A rs2369049-GG, and TRPV1 rs8065080-TT) were more likely to respond to acupuncture for hot flashes than noncarriers (70.3% vs 37.5%, P = 0.035). These six genotypes were not associated with response in women (N = 51) who received pharmacological hot flash treatment (gabapentin or placebo pill; 37.5% vs 37.5%, P = 1.0). CONCLUSIONS In this exploratory, proof of concept study, we identified six genotypes that may predict response to acupuncture for hot flashes in breast cancer survivors. If confirmed by future studies, these findings may inform the development of personalized acupuncture for managing hot flashes.

Abstract
Background Beneficial effects of placebos are high in double-blind hot flush trials. Studies in various conditions suggest that honestly prescribed placebos may elicit symptom improvement. Objective To determine whether open label placebo (OLP) treatment is efficacious in alleviating hot flushes among peri- and postmenopausal women. Methods/design In this assessor-blinded, randomized-controlled trial, n = 100 women experiencing five or more daily hot flushes of at least moderate severity and bothersomeness are assigned 1:1 to a 4-week OLP treatment or no treatment. To explore the duration and maintenance of placebo effects, the OLP group is randomized a second time to either discontinue or continue the OLP treatment for another 4 weeks. All participants receive a briefing about placebo effects and study visits at baseline, post-treatment (4 weeks), and follow-up (8 weeks, OLP group only). Qualitative interviews about subjective experiences with the OLP treatment are conducted. Primary outcomes are differences between the OLP and the no-treatment group in the hot flush composite score (frequency × severity), and bothersomeness of hot flushes as assessed with the Hot Flush Rating Scale at post-treatment. Secondary outcomes include hot flush frequency, health-related quality of life, global improvement, and the number of responders at post-treatment. Data are analyzed by fitting (generalized) linear mixed models. An exploratory analysis of maintenance and duration is performed including follow-up data. Discussion This trial will contribute to the evaluation of OLP treatments in clinical practice and further our understanding about the magnitude of placebo effects in hot flush treatments. Trial registration Clinicaltrials.gov, NCT03838523. Retrospectively registered on February 12th, 2019. The first patient was enrolled on October 10th, 2018.

Abstract
Safety concerns or contraindications to the use of hormones have resulted in a rise of the use of herbal medicinal products for the management of menopausal symptoms. The pollen extract Sérélys® represents, due to its ingredients and mode of action, a new and innovative alternative for the management of these symptoms. The aim of the present study was to demonstrate the efficacy and safety of Sérélys®. A prospective, open, observational, and multicentre study was performed on 104 menopausal women. The patients received over 3 months the pollen extract Sérélys® containing the extracts PI82 and GC Fem in a dosage of twice 160 mg extract and 5 mg vitamin E. Using a validated menopausal rating score, the improvement of menopausal symptoms was recorded. A significant decrease of different menopausal symptoms was observed between the starting point of the study and after 12 weeks (p < .0001). Hot flashes were reduced by 48.5%, sleep disturbance by 50.1%, depressive mood by 51.2%, irritability by 47.9%, fatigue by 47.8%, vaginal dryness by 39.63% and muscles and joint pain by 27.4%. The pollen extract Sérélys® reduced significant menopausal symptoms showing a very low side effect profile.

Abstract
The improved detection and successful treatment of breast cancer, resulting in better survival rates, has led to an increasing number of women living with the effects of treatment modalities and their long-term consequences. Menopausal symptoms following breast cancer can occur at an earlier age, be more severe and significantly influence a woman's overall wellbeing, in particular, sexual function, quality of life and adherence to treatment. There is a dearth of good quality evidence on the safest and most effective treatment options available for these women, and this article aims to summarize the current available treatments. Pertinent to these women is general advice, such as avoidance of triggers, and lifestyle modifications. Following which, non-pharmacological interventions, including cognitive behavior therapy (CBT), hypnosis, acupuncture, stellate ganglion nerve block and complementary agents, are discussed. Pharmacological therapies and their safety profile in these high-risk women are then examined; namely, menopausal hormone therapy, progestogens, antidepressants (selective serotonin reuptake inhibitors and selective noradrenaline reuptake inhibitors), gabapentin, clonidine and intra-vaginal dehydroepiandrosterone (DHEA). Finally, neurokinin 3 receptor antagonists, promising new agents for the treatment of troublesome menopausal vasomotor symptoms, are discussed.

Abstract
In recent years, several randomized controlled trials evaluating pharmaceutical treatments for traumatic brain injury (TBI) have failed to demonstrate efficacy over placebo, with both active and placebo arms improving at comparable rates. These findings could be viewed in opposing ways, suggesting on the one hand failure of the tested outcome, but on the other, representing evidence of robust placebo effects in TBI. In this article, we examine several of the primary psychological processes driving placebo effects (verbal suggestion, cognitive re-framing, interpersonal interactions, conditioning, therapeutic alliance, anxiety reduction) as well as placebo neurobiology (top-down cortical regulation, reward system activation, dopaminergic and serotonergic neurotransmission). We then extrapolate from the literature to explore whether something inherent in TBI makes it particularly responsive to placebos. Viewed as such here, placebos may indeed represent a powerful and effective treatment for a variety of post-TBI complaints.

Abstract
Placebo effect refers to beneficial changes induced by the use of inert treatment, such as placebo-induced relief of physical pain and attenuation of negative affect. To date, we know little about whether placebo treatment could facilitate social functioning, a crucial aspect for well-being of a social species. In the present study, we develop and validate a paradigm to induce placebo effects on social trust and approach behavior (social placebo effect), and show robust evidence that placebo treatment promotes trust in others and increases preference for a closer interpersonal distance. We further examine placebo effects in real-life social interaction and show that placebo treatment makes single, but not pair-bonded, males keep closer to an attractive first-met female and perceive less social anxiety in the female. Finally, we show evidence that the effects of placebo treatment on social trust and approach behavior can be as strong as the effect of intranasal administration of oxytocin, a neuropeptide known for its function in facilitating social cognition and behavior. The finding of the social placebo effect extends our understanding of placebo effects on improvement of physical, mental, and social well-being and suggests clinical potentials in the treatment of social dysfunction.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pueraria candollei var. mirifica (Airy Shaw & Suvat.) Niyomdham (commonly termed P. mirifica, PM) growing in upland Thailand has a long history as a postmenopausal rejuvenant therapy for indigenants. Its amelioration of menopause symptoms in clinical trials was assessed. MATERIALS AND METHODS International and Thai databases were searched from inception to February 2017. Clinical trials investigating effects of PM menopausal or postmenopausal women were included. Outcomes were self-reported menopausal symptoms, serum reproductive hormones, urino-genital tract function, and bone surrogates. Methodological quality was assessed by Cochrane risk-of-bias v2.0, and a 22-parameter quality score based on the CONSORT checklist for herbal medicines. RESULTS Eight studies (9 articles) used data from 309 menopausal patients. Five-studies demonstrated that PM was associated with climacteric scores reduced by ~50% compared to baseline. Other PM studies using limited numbers of placebo participants suggested improved vaginal and other urogenital tract symptoms. Bone alkaline phosphatase halved (suggesting lowered bone turnover). Variable serum reproductive hormone levels suggested menopausal status differed between studies. PM active ingredients and sources were not defined. Adverse event rates (mastodynia, vaginal spotting, dizziness) were similar in all groups (PM, conjugated equine estrogen, and placebos) but serum C-reactive protein doubled. These studies had design and reporting deficiencies, high risks of biases, and low quality scores. CONCLUSIONS The efficacy of PM on menopausal symptoms remains inconclusive because of methodological short-comings especially placebo effects inherent in self-assessment/recall questionnaires and no PM standardization. PM efficacy and safety need a fundamental re-appraisal by: (i) cohort (retro- and prospective) studies on current users to define its traditional use for rejuvenation; (ii) tightly coupling long-term efficacy to safety of well-defined PM and multiple end-points; (iii) using study design related to current understanding of menopause progression and estrogen pharmacology (iv) robust pharmacovigilance.

Abstract
OBJECTIVE The aim of the study was to determine the time course of effect with conjugated estrogens/bazedoxifene (CE/BZA) in nonhysterectomized postmenopausal women in five phase 3 trials. METHODS This post hoc analysis identified when CE 0.45 mg/BZA 20 mg and CE 0.625 mg/BZA 20 mg first achieved a statistically significant difference (P < 0.05) versus placebo in individual trials and the duration the difference persisted for prespecified efficacy endpoints. RESULTS CE/BZA significantly reduced hot flush frequency beginning at weeks 2 to 4 and severity at weeks 3 to 6; benefits were maintained through month 24. Significant improvements in lumbar spine, total hip, femoral neck, and femoral trochanter bone mineral density were evident at month 6 or 12 and changes in bone turnover markers at month 3 or 6; benefits were maintained throughout the studies (12 or 24 mo). In symptomatic women with less than 5% vaginal superficial cells at baseline, vaginal maturation index was significantly improved by week 4. Reductions in parabasal cells were maintained throughout the studies (through months 3 and 24), but superficial cell count changes persisted only with the higher CE/BZA dose. Menopause-Specific Quality of Life total and vasomotor domain scores were improved at all assessments, from months 3 through 24. Some measures of sleep, especially quality and time to fall asleep, improved during weeks 4 to 8 and were maintained in a majority of weeks thereafter. CONCLUSIONS In the context of studies designed primarily to evaluate efficacy at final study endpoints, both doses of CE/BZA achieved significance versus placebo at early assessments for most outcomes, and benefits were well maintained.

Abstract
Background Evidence on the impact of expectancy on acupuncture treatment response is conflicting. Objectives This secondary analysis of a randomized sham-controlled trial on acupuncture for menopausal hot flashes investigated whether treatment expectancy score was associated with hot flash score at end-of-treatment. Secondary analyses investigated whether there were associations between other pre-specified factors and hot flash score. Study design Women experiencing moderately-severe hot flashes were randomized to receive 10 sessions of real or sham acupuncture over eight weeks. Hot flash score was collected using a seven-day hot flash diary, and expectancy using the modified Credibility and Expectancy Questionnaire immediately after the first treatment. Linear mixed-effects models with random intercepts were used to identify associations between expectancy score and hot flash score at end-of-treatment. Regression was also used to identify associations between pre-specified factors of interest and hot flash score. Because there was no difference between real and sham acupuncture for the primary outcome of hot flash score, both arms were combined in the analysis. Results 285 women returned the Credibility and Expectancy Questionnaire, and 283 women completed both expectancy measures. We found no evidence for an association between expectancy and hot flash score at end-of-treatment for individual cases in either acupuncture or sham group. Hot flash scores at end-of-treatment were 8.1 (95%CI, 3.0 to 13.2; P = 0.002) points lower in regular smokers compared to those who had never smoked, equivalent to four fewer moderate hot flashes a day. Conclusion In our study of acupuncture for menopausal hot flashes, higher expectancy after the first treatment did not predict better treatment outcomes. Future research may focus on other determinants of outcomes in acupuncture such as therapist attention. The relationship between smoking and hot flashes is poorly understood and needs further exploration.

Abstract
OBJECTIVE Review evidence to guide management of menopausal signs and symptoms in women after breast cancer and make recommendations accordingly. EVIDENCE Randomized controlled clinical trials, observational studies, evidence-based guidelines, and expert opinion from professional societies. BACKGROUND Symptoms and clinical problems associated with estrogen depletion-sleep disorders, vulvovaginal atrophy (VVA), vasomotor symptoms (VMS), mood changes, depressive symptoms, cardiovascular disease, osteopenia, and osteoporosis-confront the estimated 9.3 million breast cancer survivors globally. RECOMMENDATIONS Following breast cancer, women should not generally be treated with menopausal hormone therapy or tibolone but should optimize lifestyle. Women with moderate to severe symptoms may benefit from mind-brain behavior or nonhormone, pharmacologic therapy. The selective serotonin/noradrenaline reuptake inhibitors and gabapentenoid agents improve VMS and quality of life. For osteoporosis, nonhormonal agents are available. Treatment of VVA remains an area of unmet need. Low-dose vaginal estrogen is absorbed in small amounts with blood levels remaining within the normal postmenopausal range but could potentially stimulate occult breast cancer cells, and although poorly studied, is not generally advised, particularly for those on aromatase inhibitors. Intravaginal dehydroepiandrosterone and oral ospemiphene have been approved to treat dyspareunia, but safety after breast cancer has not been established. Vaginal laser therapy is being used for VVA but efficacy from sham-controlled studies is lacking. Therapies undergoing development include lasofoxifene, neurokinin B inhibitors, stellate ganglion blockade, vaginal testosterone, and estetrol. CONCLUSIONS Nonhormone options and therapies are available for treatment of estrogen depletion symptoms and clinical problems after a diagnosis of breast cancer. Individualization of treatment is essential.

Abstract
BACKGROUND Placebo medications, by definition, are composed of inactive ingredients that have no physiological effect on symptoms. Nonetheless, administration of placebo in randomized controlled trials (RCTs) and in clinical settings has been demonstrated to have significant impact on many physical and psychological complaints. Until recently, conventional wisdom has suggested that patients must believe that placebo pills actually contain (or, at least, might possibly contain) active medication in order to elicit a response to placebo. However, several recent RCTs, including patients with irritable bowel syndrome (IBS), chronic low back pain, and episodic migraine, have demonstrated that individuals receiving open-label placebo (OLP) can still experience symptomatic improvement and benefit from honestly described placebo treatment. METHODS AND DESIGN This paper describes an innovative multidisciplinary trial design (n = 280) that attempts to replicate and expand upon an earlier IBS OLP study. The current study will compare OLP to double-blind placebo (DBP) administration which is made possible by including a nested, double-blind RCT comparing DBP and peppermint oil. The study also examines possible genetic and psychological predictors of OLP and seeks to better understand participants' experiences with OLP and DBP through a series of extensive interviews with a randomly selected subgroup. DISCUSSION OLP treatment is a novel strategy for ethically harnessing placebo effects. It has potential to re-frame theories of placebo and to influence how physicians can optimize watch-and-wait strategies for common, subjective symptoms. The current study aims to dramatically expand what we know about OLP by comparing, for the first time, OLP and DBP administration. Adopting a unique, multidisciplinary approach, the study also explores genetic, psychological and experiential dimensions of OLP. The paper ends with an extensive discussion of the "culture" of the trial as well as potential mechanisms of OLP and ethical implications.

Abstract
Placebos are sham medical treatments. Nonetheless, they can have substantial effects on clinical outcomes. Placebos depend on a person's psychological and brain responses to the treatment context, which influence appraisals of future well-being. Appraisals are flexible cognitive evaluations of the personal meaning of events and situations that can directly impact symptoms and physiology. They also shape associative learning processes by guiding what is learned from experience. Appraisals are supported by a core network of brain regions associated with the default mode network involved in self-generated emotion, self-evaluation, thinking about the future, social cognition, and valuation of rewards and punishment. Placebo treatments for acute pain and a range of clinical conditions engage this same network of regions, suggesting that placebos affect behavior and physiology by changing how a person evaluates their future well-being and the personal significance of their symptoms.

Abstract
Menopausal symptoms (eg, hot flushes and vaginal symptoms) are common, often bothersome, and can adversely impact women's sexual functioning, relationships, and quality of life. Estrogen-progestin therapy was previously considered the standard care for hormone therapy (HT) for managing these symptoms in nonhysterectomized women, but has a number of safety and tolerability concerns (eg, breast cancer, stroke, pulmonary embolism, breast pain/tenderness, and vaginal bleeding) and its use has declined dramatically in the past decade since the release of the Women's Health Initiative trial results. Conjugated estrogens paired with bazedoxifene (CE/BZA) represent a newer progestin-free alternative to traditional HT for nonhysterectomized women. CE/BZA has demonstrated efficacy in reducing the frequency and severity of vasomotor symptoms and preventing loss of bone mineral density in postmenopausal women. CE/BZA provides an acceptable level of protection against endometrial hyperplasia and does not increase mammographic breast density. Compared with traditional estrogen-progestin therapy, it is associated with lower rates of breast pain/tenderness and vaginal bleeding. Patient-reported outcomes indicate that CE/BZA improves menopause-specific quality of life, sleep, some measures of sexual function (especially ease of lubrication), and treatment satisfaction. This review looks at the rationale for selection and combination of CE with BZA at the dose ratio in the approved product and provides a detailed look at the efficacy, safety, tolerability, and patient-reported outcomes from the five Phase III trials. Patient considerations in the choice between CE/BZA and traditional HT (eg, tolerability, individual symptoms, and preferences for route of administration) are also considered.
