RESUMO
PURPOSE: To evaluate the positive predictive value (PPV) of an endometrial cancer case finding algorithm using International Classification of Disease 10th revision Clinical Modification (ICD-10-CM) diagnosis codes from US insurance claims for implementation in a planned post-marketing safety study. Two algorithm variants were evaluated. METHODS: Provisional incident endometrial cancer cases were identified from 2016 through 2020 among women aged ≥50 years. One algorithm variant used diagnosis codes for malignant neoplasms of uterine sites (C54.x), excluding C54.2 (malignant neoplasm of myometrium); the other used only C54.1 (malignant neoplasm of endometrium). A random sample of medical records of recent incident provisional cases (2018-2020) was requested for adjudication. Confirmed cases showed biopsy evidence of endometrial cancer, documentation of cancer staging, or hysterectomy following diagnosis. We estimated the PPV of the variants with 95% confidence intervals (CI) excluding cases that had insufficient information. RESULTS: Of 294 provisional cases adjudicated, 85% were from outpatient settings (n = 249). Mean age at diagnosis was 69.3 years. Among the 294 adjudicated cases (identified with the broader algorithm variant), the same 223 were confirmed endometrial cancer cases by both algorithm variants. The PPV (95% CI) for the broader algorithm variant was 84.2% (79.2% and 88.3%), and for the variant using only C54.1 was 85.8% (80.9% and 89.8%). CONCLUSION: We developed and validated an algorithm using ICD-10-CM diagnosis codes to identify endometrial cancer cases in health insurance claims with a sufficiently high PPV to use in a planned post-marketing safety study.

Objective: The objective of the present document was to review/summarize reported outcomes compared between menopausal hormone therapy (MHT) containing estradiol (E2) versus other estrogens and MHT with progesterone (P4) versus progestins (defined as synthetic progestogens).Methods: PubMed and EMBASE were systematically searched through February 2021 for studies comparing oral E2 versus oral conjugated equine estrogens (CEE) or P4 versus progestins for endometrial outcomes, venous thromboembolism (VTE), cardiovascular outcomes, breast outcomes, cognition, and bone outcomes in postmenopausal women.Results: A total of 74 comparative publications were identified/summarized. Randomized studies suggested that P4 and progestins are likely equally effective in preventing endometrial hyperplasia/cancer when used at adequate doses. E2- versus CEE-based MHT had a similar or possibly better risk profile for VTE and cardiovascular outcomes, and P4- versus progestin-based MHT had a similar or possibly better profile for breast cancer and cardiovascular outcomes. E2 may potentially protect better against age-related cognitive decline and bone fractures versus CEE; P4 was similar or possibly better versus progestins for these outcomes. Limitations are that many studies were observational and some were not adequately powered for the reported outcomes.Conclusions: Evidence suggests a differential effect of MHT containing E2 or P4 and those containing CEE or progestins, with some evidence trending to a potentially better safety profile with E2 and/or P4.

INTRODUCTION: Vulvar and vaginal atrophy (VVA) affects up to two thirds of postmenopausal women, but most symptomatic women do not receive prescription therapy. AIM: To evaluate postmenopausal women's perceptions of VVA and treatment options for symptoms in the Women's EMPOWER survey. METHODS: The Rose Research firm conducted an internet survey of female consumers provided by Lightspeed Global Market Insite. Women at least 45 years of age who reported symptoms of VVA and residing in the United States were recruited. MAIN OUTCOME MEASURES: Survey results were compiled and analyzed by all women and by treatment subgroups. RESULTS: Respondents (N = 1,858) had a median age of 58 years (range = 45-90). Only 7% currently used prescribed VVA therapies (local estrogen therapies or oral selective estrogen receptor modulators), whereas 18% were former users of prescribed VVA therapies, 25% used over-the-counter treatments, and 50% had never used any treatment. Many women (81%) were not aware of VVA or that it is a medical condition. Most never users (72%) had never discussed their symptoms with a health care professional (HCP). The main reason for women not to discuss their symptoms with an HCP was that they believed that VVA was just a natural part of aging and something to live with. When women spoke to an HCP about their symptoms, most (85%) initiated the discussion. Preferred sources of information were written material from the HCP's office (46%) or questionnaires to fill out before seeing the HCP (41%).The most negative attributes of hormonal products were perceived risk of systemic absorption, messiness of local creams, and the need to reuse an applicator. Overall, HCPs only recommended vaginal estrogen therapy to 23% and oral hormone therapies to 18% of women. When using vaginal estrogen therapy, less than half of women adhered to and complied with posology; only 33% to 51% of women were very to extremely satisfied with their efficacy. CONCLUSION: The Women's EMPOWER survey showed that VVA continues to be an under-recognized and under-treated condition, despite recent educational initiatives. A disconnect in education, communication, and information between HCPs and their menopausal patients remains prevalent. Kingsberg S, Krychman M, Graham S, et al.

INTRODUCTION: Postmenopausal women's knowledge about vulvar and vaginal atrophy (VVA) and available treatment options has historically been inadequate. Recent direct-to-consumer marketing and educational efforts would have been expected to increase awareness and treatment options. AIM: To compare results of the Women's EMPOWER survey with other available VVA surveys to assess progress in women's understanding and approaches to treatment of VVA. METHODS: The Women's EMPOWER survey, an internet-based survey of US women with VVA symptoms, assessed women's awareness of VVA and their behaviors and attitudes associated with symptom treatment. MAIN OUTCOME MEASURES: These survey results were compared with previously published results of the Revealing Vaginal Effects at Mid-Life (REVEAL), Women's Voices in Menopause (WVM), Vaginal Health: Insight, Views, & Attitudes (VIVA), Clarifying Vaginal Atrophy's Impact on Sex and Relationship (CLOSER), and Real Women's Views of Treatment Options for Menopausal Vaginal Changes (REVIVE) surveys. RESULTS: Results of the Women's EMPOWER survey were consistent with those of past VVA surveys and showed that postmenopausal women generally failed to recognize VVA and its chronic, progressive process and that they were reluctant to discuss vaginal or sexual symptoms with their health care professionals (HCPs). However, women indicated a strong desire for accurate medical information about VVA from their health care professionals and a willingness to learn if HCPs would initiate the conversation. Most women believed that vaginal symptoms are a normal part of aging and they just need to cope with the symptoms. In the United States, women were most concerned with safety-related issues, including increased risk of breast cancer, side effects, and systemic absorption. CONCLUSION: The Women's EMPOWER survey demonstrates and reinforces that even with multimedia marketing and educational strategies in the years after other major VVA surveys, minimal progress has been made toward increasing women's awareness of, knowledge about, or understanding of VVA. Based on these data, a focus on initiating discussions and education with postmenopausal women so that they better comprehend VVA as a chronic progressive medical condition (not just aging), the symptoms associated with VVA, and the benefit-risk profile regarding treatment options is warranted.

INTRODUCTION: TX-004HR is an investigational, applicator-free, vaginal soft gel capsule containing low-dose solubilized 17ß-estradiol. The phase 3, randomized, double-blinded, placebo-controlled, multicenter REJOICE trial has shown TX-004HR to be safe and effective for the treatment of moderate to severe dyspareunia in postmenopausal women with vulvar and vaginal atrophy (VVA). AIM: To evaluate the effect of TX-004HR on female sexual dysfunction in postmenopausal women with VVA. METHODS: The REJOICE study compared the effects of 12-week treatment with TX-004HR (4, 10, or 25 µg) with placebo in postmenopausal women (40-75 years old) with VVA and a most bothersome symptom of moderate to severe dyspareunia. Changes in the percentage of superficial and parabasal cells, vaginal pH, and dyspareunia were measured as co-primary end points. Female sexual dysfunction was evaluated as a secondary end point using the Female Sexual Function Index (FSFI) patient self-report inventory. MAIN OUTCOME MEASURES: Changes from baseline to week 12 in total and individual domain FSFI scores for each TX-004HR dose were compared with those for placebo. RESULTS: All three TX-004HR doses increased the baseline total FSFI score after 12 weeks, with 10 µg (P < .05) and 25 µg (P = .0019) having a significantly greater effect than placebo. A similar trend was observed for the individual FSFI domains, with 10 and 25 µg significantly improving baselines scores for pain and lubrication at 12 weeks (P ≤ .015 for all vs placebo). Changes from baseline to week 12 in arousal (P = .0085) and satisfaction (P = .0073) were significantly greater for TX-004HR 25 µg vs placebo. All three TX-004HR doses were comparable to placebo in their effect on desire and orgasm. CONCLUSION: TX-004HR improved FSFI scores in a dose-dependent manner. The observed improvements in sexual function suggest that TX-004HR is a promising treatment option for postmenopausal VVA with a potential added beneficial effect on female sexual dysfunction.

Ospemifene is a nonestrogen tissue-selective estrogen agonist/antagonist approved to treat moderate to severe dyspareunia due to vulvar and vaginal atrophy in postmenopausal women. Three single-dose, open-label, parallel-group pharmacokinetic studies examined the pharmacokinetics of ospemifene in postmenopausal women with (1) mild hepatic impairment (n = 7), (2) moderate hepatic impairment (n = 8), and (3) severe renal impairment (n = 8) compared with a similar number of matched healthy controls. The study durations ranged from 8 to 12 days. Study participants received a single oral dose of ospemifene 60 mg on day 1 and blood samples were collected serially. The geometric mean ratios (hepatic or renal impairment/healthy) and 90% confidence intervals (CIs) for area under the concentration-time curve from time 0 extrapolated to infinity (AUC0-∞) and maximum concentration (Cmax), respectively, of ospemifene were 90.86% (90% CI, 65.95%-125.19%) and 79.48% (90% CI, 65.95%-95.79%) in the mild hepatic impairment study; 128.62% (90% CI, 87.13%-189.88%) and 101.12% (90% CI, 66.17%-154.52%) in the moderate hepatic impairment study, and 119.63% (90% CI, 81.37%-175.88%) and 79.30% (90% CI, 52.85%-118.99%) in the severe renal impairment study. Overall, there was no clinically important effect of hepatic or renal impairment on the pharmacokinetics of ospemifene, indicating that dosing does not need to be adjusted in postmenopausal women with mild or moderate hepatic impairment or in subjects with severe renal impairment.

INTRODUCTION: Ospemifene is a new oral estrogen receptor agonist/antagonist with tissue-selective effects approved for the treatment of moderate to severe dyspareunia, a symptom of postmenopausal vulvar and vaginal atrophy (VVA). AIM: The aim of the study is to assess ospemifene or lubricant use on the clinical signs of VVA. METHODS: Subjects in three double-blind, placebo-controlled clinical trials were randomized to ospemifene or placebo. In two of the trials, women were provided nonhormonal lubricants for use as needed, and a preplanned evaluation of the frequency of lubricant use was performed. Additionally, a post hoc placebo group analysis for impact of lubricant use or nonuse on physiologic effects of the percentage of superficial and parabasal cells (maturation index) and vaginal pH was conducted. A secondary preplanned end point included visual examination of the vagina (clinical signs of vaginal dryness, petechiae, pallor, friability, and redness of the mucosa) comparing change from baseline to end of treatment for the ospemifene 60-mg/day group and vs. placebo. MAIN OUTCOME MEASURES: The primary end points in the phase 3 clinical trials included the percentage of superficial cells, parabasal cells, vaginal pH, and most bothersome symptoms compared with placebo. RESULTS: There was no significant difference in physiologic effects between placebo lubricant users vs. nonusers in either 12-week study. Compared with baseline, substantially more subjects receiving ospemifene 60 mg/day than placebo showed complete resolution of clinical signs of VVA after 12 and 52 weeks of treatment. CONCLUSIONS: Ospemifene substantially improved clinical signs of VVA. Within the placebo group, there was no difference in physiologic effects in lubricant users vs. nonusers. Based on gynecologic evaluation of the vagina, benefits were apparent at 12 weeks and sustained for 52 weeks in the ospemifene-treated subjects with significant improvement over placebo. In these three clinical trials, in contrast to ospemifene-treated women, placebo subjects who utilized lubricants had no improvement in their underlying vaginal physiology.

Background: We evaluated satisfaction with use of a segesterone acetate and ethinyl estradiol (0.15/0.013 mg) contraceptive vaginal system (CVS) among women who had recently used a monthly contraceptive vaginal ring or contraceptive pills. The CVS is a ring-shaped device used in a 21-days-in/7-days-out regimen for 13 cycles. Materials and Methods: We analyzed post hoc satisfaction responses at cycle 3 and end of study (EOS) from a subset of participants with documented recent use of the monthly ring or daily pills before enrollment in a multinational, phase 3, 13-cycle trial evaluating the CVS. EOS included results from participants who had completed ≥10 cycles. Results were summarized descriptively. Results: We identified 128 recent ring and 219 recent pill users at cycle 3 (of 1033 survey participants), and 92 and 148, respectively, at EOS (of 622 survey participants); overall satisfaction with CVS use was high (≥90%). At EOS, most ring (89%) and pill (97%) users liked the CVS as much/better than any previous method. The two most-liked CVS features included ease of use and 1-year duration; the two most disliked features included ring insertion and feeling it coming out. At EOS, ≥88% of both groups reported no concern about using the same CVS for a year, and most (>80%) had recommended it to friends or family members. Conclusion: The CVS clinical trial participants who were recent ring/pill users reported high satisfaction and liked it as much/better than any previously used contraceptive; the CVS may be a good contraceptive option for switchers. Clinical trial registration NCT00263341.

OBJECTIVE: To evaluate bone turnover markers (BTM) in the REPLENISH trial (NCT01942668). METHODS: REPLENISH evaluated oral estradiol/progesterone (E2/P4) for the treatment of moderate to severe vasomotor symptoms (VMS) in postmenopausal women with a uterus. Eligible women for this analysis had ≥50 moderate to severe VMS/wk, were <5âyears since last menstrual period, and had BTM measurements at baseline, and months 6 and 12. Percent changes for three BTM (bone-specific alkaline phosphatase [BSAP], C-terminal telopeptide of type I collagen [CTX-1], and N-terminal propeptide of type I procollagen [P1NP]) assessed by immunoassay methods were evaluated from baseline to months 6 and 12 for the 1âmg E2/100âmg P4, 0.5âmg E2/100âmg P4, and placebo groups. RESULTS: A total of 157 women (40-61ây, 69% White) were analyzed. Mean baseline values ranged from 14.0 to 14.3âU/L for BSAP, 0.34 to 0.39âng/mL for CTX-1, and 76.9 to 79.3âng/mL for PINP. Mean differences in percent change from baseline for both E2/P4 doses versus placebo significantly decreased at months 6 and 12 and ranged from -8% to -16% for BSAP (all, Pâ<â0.05), -30% to -41% for CTX-1 (all, P ≤ 0.001), and -14% to -29% for PINP (all, Pâ<â0.01). CONCLUSIONS: REPLENISH data provide support for a potential skeletal benefit of E2/P4 when it is used for the treatment of moderate to severe VMS. Further studies are warranted.

OBJECTIVE: To evaluate endometrial progesterone receptor (PGR) expression in menopausal women who used vaginal 4-µg and 10-µg estradiol (E2) inserts or placebo. METHODS: REJOICE was a randomized, placebo-controlled trial investigating vaginal E2 inserts in women with moderate to severe dyspareunia due to menopause. In this post hoc analysis, 25 eligible women with endometrial biopsies were randomly selected from each treatment group (4-µg and 10-µg E2 vaginal inserts and placebo). Endometrial biopsy sections were immunostained using an anti-PR (A and B) monoclonal antibody. Cell staining was quantified using an artificial intelligence feature-recognition algorithm. Mean PGR expression levels were analyzed between baseline and week 12. RESULTS: PGR expression results were available for 22 women in the 4-µg E2 group, and 25 women each for the 10-µg E2 and placebo groups. Similar PGR expression levels were observed at baseline (0.301-0.470âpmol/mg) and after 12âweeks of treatment (0.312-0.432âpmol/mg) for all treatment groups, with no significant differences between baseline and week 12. CONCLUSIONS: No meaningful differences in endometrial PGR expression were observed with the vaginal E2 (4- and 10-µg) inserts at week 12 from baseline, supporting the hypothesis that local exposure to E2 from a low-dose, vaginal insert placed near the vaginal introitus will not be sufficient to upregulate endometrial PGR expression. Coupled with the lack of histologic changes and systemic absorption, our data suggest that these softgel vaginal E2 inserts would not be expected to stimulate endometrial hyperplasia leading to a potential endometrial safety issue in postmenopausal women with moderate to severe dyspareunia, a symptom of vulvar and vaginal atrophy. Further study on the endometrial safety of softgel vaginal E2 inserts is under way.

OBJECTIVE: To predict serum segesterone (SA) and ethinyl estradiol (EE) levels after 364 days of hypothetical continuous use (without removal) of a cyclic contraceptive vaginal system (CVS) containing 0.15 mg SA and 0.013 mg EE. STUDY DESIGN: We used pharmacokinetic (PK) data (n = 37) from a multicenter, open-label, nonrandomized study of healthy women (18-38 years) that used the CVS for 13 cycles in a 21 days-in/7 days-out regimen to develop a linear regression model to predict daily serum SA and EE levels for 364 days of continuous CVS use. We then determined residual SA/EE levels in vitro from 18 randomly chosen CVS used by women who completed 13 cycles. Serum SA and EE levels were also predicted for 364 days of continuous CVS use in another in vitro study. RESULTS: After a hypothetical 364 days of continuous CVS use, we predicted daily mean serum levels to be 184 pmol/L (95% confidence interval [CI], 102â332 pmol/L) for SA and 43 pmol/L (95% CI, 19â95 pmol/L) for EE. We did predict that serum EE levels would not accumulate over time. Residual SA and EE in the CVS were 60% and 80% of the original load after 13 cycles, respectively. CONCLUSION: The predicted serum SA level after 364 days of hypothetical continuous CVS use was comparable to reported levels at which no pregnancy occurred (>100 pmol/L), showing the potential of the CVS for one year of continuous use. Clinical trials on continuous CVS use are planned. IMPLICATIONS: Based on statistical modeling, the long-term, user-controlled contraceptive vaginal system containing segesterone acetate and ethinyl estradiol may have the potential to provide effective pregnancy prevention if used continuously (without removal) for one year. Further investigation is warranted.

OBJECTIVE: To examine the impact of a single-capsule 17ß-estradiol (E2)/progesterone (P4) on weight and blood pressure (BP) when treating moderate to severe vasomotor symptoms in postmenopausal women with a uterus. METHODS: Healthy postmenopausal women with a uterus (aged 40-65, body mass index ≤34âkg/m2, BP ≤140/90 mm Hg) were randomized to daily E2/P4â(mg/mg; 1/100, 0.5/100, 0.5/50, 0.25/50) or placebo in the phase 3 REPLENISH trial (NCT01942668). Changes in weight and BP from baseline to month 12 were evaluated. Potentially clinically important changes were defined as increases or decreases from baseline in weight by ≥15% and ≥11.3âkg, systolic BP by ≥20 mm Hg (absolute value ≥160 or ≤90 mm Hg), and diastolic BP by ≥15 mm Hg (absolute value ≥90 or ≤60 mm Hg). RESULTS: Overall mean changes in weight and BP from baseline to month 12 with E2/P4 were modest and generally not statistically or clinically significant versus placebo. Incidence of potentially clinically important changes was low for weight (E2/P4 vs placebo: 1.1-2.6% vs 2.2%), systolic BP (0.3-1.1% vs 1.1%), and diastolic BP (1.4-4.2% vs 3.2%). A small number of women had treatment-related, treatment-emergent adverse events of weight gain (1.4-2.6% vs 1.3%) or hypertension (0.2-1.2% vs 0%). Few women who discontinued E2/P4 had weight gain (1.6%) or hypertension (0.6%) as a primary reason. Efficacy profile on VMS was consistent with previous findings and not modified by body mass index. CONCLUSIONS: Twelve-month use of E2/P4 had no clinically meaningful impact on weight or BP in postmenopausal women of the REPLENISH study.

OBJECTIVE: To evaluate the effect of a single-capsule, bioidentical 17ß-estradiol (E2) and progesterone (P4) hormone therapy on mammograms and breasts in postmenopausal women after 1 year of use. METHODS: In the 12-month, phase 3, randomized, double-blind, placebo-controlled, multicenter REPLENISH trial, postmenopausal women (40-65 y) with moderate to severe vasomotor symptoms and a uterus were randomized to four active daily dose groups of E2/P4 (TX-001HR) or a placebo group. Mammograms were performed and read locally at screening (or ≤6 months before first dose) and at study end using BI-RADS classification. Incidence of abnormal mammograms and breast adverse events was evaluated. RESULTS: All but 8 (0.4%) mammograms at screening were normal (BI-RADS 1 or 2). At 1 year, 39 (2.9%) of the 1,340 study-end mammograms were abnormal (BI-RADS 3 or 4); incidence was 1.7% to3.7% with active doses and 3.1% with placebo. Breast cancer incidence was 0.36% with active doses and 0% with placebo. Breast tenderness was reported at frequencies of 2.4% to 10.8% with active doses versus 0.7% with placebo, and led to eight study discontinuations (1.6% of discontinuations in active groups). CONCLUSIONS: In this phase 3 trial of a combined E2/P4, results of secondary outcomes suggest that E2/P4 may not be associated with increased risk of abnormal mammograms versus placebo, and the incidence of breast tenderness was low relative to most of the rates reported in other studies using hormone therapy.

OBJECTIVE: To examine responder rates and vasomotor symptom-free days with oral 17ß-estradiol/progesterone (E2/P4; TX-001HR) versus placebo in the REPLENISH trial. METHODS: REPLENISH (NCT01942668) was a phase 3, randomized, double-blind, placebo-controlled, multicenter trial, evaluating single, oral, softgel E2/P4 capsules in postmenopausal women (40-65 y) with a uterus and vasomotor symptoms (VMS). Women with moderate to severe hot flushes (≥7/d or ≥50/wk) were randomized (VMS substudy) to daily E2/P4â(mg/mg) of 1/100, 0.5/100, 0.5/50, 0.25/50, or placebo. Proportions of women with ≥50% or ≥75% reductions in moderate to severe VMS (responders), and those with no severe VMS as well as the weekly number of days without moderate to severe VMS with TX-001HR versus placebo were determined. Mixed model repeated measures was used to analyze data and Fisher exact test was employed to compare E2/P4 versus placebo. RESULTS: Seven hundred twenty-six women were eligible for the VMS efficacy analysis (E2/P4â1/100 [nâ=â141], 0.5/100 [nâ=â149], 0.5/50 [nâ=â147], 0.25/50 [nâ=â154], or placebo [nâ=â135]). Significantly more women treated with all E2/P4 doses versus placebo were ≥50% responders and ≥75% responders at weeks 4 and 12 (Pâ<â0.05) and also had significantly more days per week without moderate to severe VMS at week 12 (1.9-3.0 d for E2/P4 versus 1.3 d for placebo; Pâ<â0.05). The proportion of women without severe hot flushes at week 12 was 43% to 56% for all E2/P4 doses versus 26% for placebo (P ≤ 0.01). CONCLUSIONS: Women treated with E2/P4 had a greater response to treatment with more VMS-free days than with placebo. The E2/P4â1/100 dose (Bijuva [E2 and P4] capsules) represents an oral treatment option for postmenopausal women with moderate to severe VMS and a uterus.

OBJECTIVE: The aim of the study was to evaluate the clinically meaningful effect of oral TX-001HR (17ß-estradiol [E2]/progesterone [P4]) capsules on hot flushes severity (vasomotor symptoms [VMS] severity scale) using the patient-reported Clinical Global Impression (CGI). METHODS: REPLENISH (NCT01942668) was a phase 3, randomized, double-blind, placebo-controlled, multicenter trial that evaluated TX-001HR in postmenopausal women (40-65 y) with a uterus. Those with frequent moderate to severe hot flushes (≥7/d or ≥50/wk) were randomized in a VMS substudy to daily E2/P4 (1/100, 0.5/100, 0.5/50, or 0.25/50âmg/mg), or placebo. Patients rated VMS severity from 1 (mild) to 3 (severe) and symptom improvements with the CGI. CGI results were an anchor in a nonparametric discriminant analysis to define clinically important differences (CIDs) and minimal CID in VMS severity at weeks 4 and 12. RESULTS: In the VMS substudy (nâ=â726), determined CID and minimal CID severity thresholds were reductions of 0.525 and 0.350 points at week 4, respectively, and 0.775 and 0.225 points at week 12. Significantly more women taking the two highest E2/P4 doses (1/100 and 0.5/100) versus placebo met CID severity thresholds at weeks 4 (40% and 44% vs 17%; Pâ<â0.05) and 12 (56% and 48% vs 29%; Pâ<â0.05). CONCLUSION: REPLENISH trial data demonstrated that E2/P4 1/100 and 0.5/100 provided clinically meaningful improvements in hot flushes severity in postmenopausal women. In conjunction with previously demonstrated clinically meaningful VMS frequency improvements, these data support oral E2/P4 1/100 and 0.5/100 for postmenopausal women with a uterus seeking treatment for moderate to severe VMS.

OBJECTIVE: The aim of the study was to evaluate the effect of a single-capsule 17ß-estradiol/progesterone (E2/P4), TX-001HR, on endometrial safety, to report on amenorrhea and bleeding patterns of users, and to identify predictors of amenorrhea. METHODS: The REPLENISH trial (NCT01942668) evaluated use of TX-001HR in menopausal women (40-65 y) with vasomotor symptoms (VMS) and a uterus. Women were randomized to daily E2/P4 (mg/mg: 1/100, 0.5/100, 0.5/50, or 0.25/50), or placebo for 12 months. Incidence rate of endometrial hyperplasia was calculated from endometrial biopsies conducted at screening and study completion. Women reported bleeding and spotting in daily diaries. The number of bleeding and/or spotting days and the proportion of women with no bleeding or amenorrhea were compared between treatment and placebo using the Fisher exact test. Predictors of cumulative amenorrhea were assessed by univariate analyses. RESULTS: Women (nâ=â1,835) who took at least one study dose comprised the safety population; 1,255 had baseline and 12-month biopsies and comprised the endometrial safety population. Incidence of endometrial hyperplasia was ≤0.36% with any dose of TX-001HR after 1 year of use (one-sided upper 95% confidence interval ≤4%). Cumulative amenorrhea (no bleeding/spotting) rates increased over time and were relatively high from cycle 1 to 13 with TX-001HR (56%-73%; placebo 79%; Pâ<â0.05 except with 0.25/50 dose). Few vaginal bleeding adverse events (1.0%-4.6% TX-001HR vs 0.7% placebo) were reported and discontinuations due to bleeding were low (0.4%-1.4% vs 0%). Cumulative amenorrhea was significantly more frequent in older women, those further from their last menstrual period, and those with lower baseline E2 concentrations (all; Pâ<â0.01). CONCLUSIONS: All doses of TX-001HR provided endometrial protection and were associated with an improved bleeding profile over time; older age, further last menstrual period, or lower baseline E2 may predict amenorrhea with TX-001HR.

OBJECTIVE: TX-004HR is a low-dose estradiol (E2) softgel vaginal insert designed to be rapidly dissolving and mucoadhesive. This report describes the physical attributes and pharmacokinetic parameters of the softgel vaginal insert evaluated for the treatment of moderate to severe dyspareunia due to menopausal vulvar and vaginal atrophy. METHODS: In vitro dissolution studies with 25-µg E2 inserts were performed and media samples were analyzed for E2 by high-performance liquid chromatography. Effects of body position on E2 bioavailability were assessed in a phase 1, randomized trial of the 25-µg softgel capsule versus a reference product in which women remained supine after dosing (nâ=â16), and in a substudy (nâ=â16) in which women were ambulatory or seated after dosing. Estradiol C max, AUC0-24, and t max were measured by high-performance liquid chromatography-tandem mass spectroscopy. A phase 2, randomized study (nâ=â50) of 10-µg E2 versus placebo inserts assessed timing of capsule disintegration at days 1 and 15. RESULTS: In vitro testing detected more than 80% of E2 in the dissolution medium by 15 minutes (first time point measured). In the phase 1 studies, baseline-corrected E2 plasma levels were not significantly different regardless of supine versus ambulatory/seated position after dosing: C max, 24.1 versus 34.3âpg/mL; AUC0-24, 77.6 versus 93.7âhâ·âpg/mL; and t max, 2.1 versus 1.9âhours, respectively. In the phase 2 study, no remnants of the softgel capsule were found at day 1 (6âhours) after dosing and day 15. Vaginal discharge was minimal (1/48 women; 2.1%). CONCLUSIONS: The presented data support rapid dissolution of the softgel capsule and similar E2 pharmacokinetic parameters regardless of body position after dosing.

BACKGROUND: The Surveillance, Epidemiology, and End Result (SEER) database shows a variable increase in endometrial cancer incidence over time. The objective of this review was to examine published endometrial cancer rates and potential etiologies. METHODS: Endometrial cancer incidence was obtained from the SEER Program database from 1975 through 2014, and a test for trend in incidence was calculated. Changes in risk factors thought to be associated with endometrial cancer, including age, obesity, diabetes, diet and exercise, reproductive factors, and medications (hormone therapy [HT] including Food and Drug Administration [FDA]-approved and non-FDA-approved [compounded] estrogens and progestogens, tamoxifen, and hormonal contraceptives) were found through PubMed searches. Temporal trends of risk factors were compared with endometrial cancer trends from SEER. RESULTS: Although endometrial cancer rates were constant from 1992 to 2002 (women 50-74 years of age), they increased 2.5% annually with a 10% increase from 2006 to 2012 (trend test 0.82). Use of approved prescription estrogen-progestogen combination products decreased after the publication of the Women's Health Initiative (WHI) data, whereas other risk factors either remained constant or decreased during the same time; however, compounded bioidentical HT (CBHT) use increased coincident with the endometrial cancer increase. CONCLUSION: Endometrial cancer rate increases after the first publication of WHI data in 2002 may be associated with the decreased use of approved estrogen-progestogen therapy, the increase in CBHT use, and the prevalence of obesity and diabetes; potential relationships require further evaluation.

OBJECTIVE: The aim of the study was to describe the effects of TX-001HR (17ß-estradiol [E2] and natural progesterone [P4] in a single oral capsule) on menopause-specific quality of life in women with moderate to severe vasomotor symptoms (VMS). METHODS: The REPLENISH study (NCT01942668) was a phase 3, randomized, double-blind, placebo-controlled, multicenter trial which evaluated four E2/P4 doses in postmenopausal women with VMS and a uterus. Women with moderate to severe hot flushes (≥7/d or ≥50/wk) were included in a VMS substudy. Participants self-administered the Menopause-Specific Quality of Life (MENQOL) questionnaire. Baseline changes in MENQOL overall and domains were determined as well as correlations between changes in MENQOL scores and VMS frequency or severity. RESULTS: In the VMS substudy, women treated with E2/P4 had significantly greater improvements from baseline in their MENQOL overall score at week 12, and months 6 and 12, compared with placebo (all, Pâ<â0.05, except the lowest E2/P4 dose at months 6 and 12). Improvements from baseline for the MENQOL vasomotor domain score were significantly greater with TX-001HR doses versus placebo at all time points (all, Pâ<â0.01). Changes in MENQOL vasomotor scores moderately correlated with changes in VMS frequency (râ=â0.56, Pâ<â0.0001) and severity (râ=â0.55, Pâ<â0.0001). CONCLUSION: In the REPLENISH trial, women with moderate to severe VMS treated with most E2/P4 doses reported significant improvements in quality of life from baseline to 12 weeks compared with placebo, which were maintained up to 12 months. TX-001HR, if approved, may provide the first oral hormone therapy formulation in a single capsule containing E2 and P4 for the treatment of VMS in postmenopausal women with a uterus.
