Is the multinational, surveillance PRO-E2 study informative for all countries? The Italian data on VTE and contraceptive effectiveness.

PURPOSE: To evaluate whether the thromboembolic risk and contraceptive effectiveness of NOMAC-E2 observed in the PRO-E2 study can be extended to each participating country, as lifestyle, cardiovascular risk factors and prescribing habits may differ geographically. This analysis was performed on the PRO-E2 Italian subpopulation, where smoking habit and women over 35 years were more prevalent compared with the overall study population. MATERIALS AND METHODS: Data from NOMAC-E2 or levonorgestrel-containing COCs (COCLNG) new users were descriptively analysed. Incidence rates of thrombosis (events/10,000 women-years [WY]) and the Pearl Index (pregnancies/100 WY) were calculated. RESULTS: Overall, 11,179 NOMAC-E2 and 8,504 COCLNG users were followed up to 2 years (34,869 WY). The NOMAC-E2 cohort included more women over 35 vs. COCLNG (37.7% vs. 31.8%; p = 0.001). A comparable low risk of combined deep venous thrombosis of lower extremities (DVT) and pulmonary embolism (PE) was observed in NOMAC-E2 (1.7/10,000 WY; 95% CI: 0.21-6.2) and COCLNG users (6.6/10,000 WY; 95% CI: 2.4-14.4). Similar results were obtained by considering all thromboembolic events (VTE). Unintended pregnancies did not differ between NOMAC-E2 (0.12/100 WY; 95% CI: 0.06-0.21) and COCLNG (0.15/100 WY; 95% CI: 0.08-0.26) cohorts. CONCLUSION: Despite the higher age and tobacco use, findings from the Italian subpopulation were broadly consistent with overall PRO-E2 results, confirming a similar low thromboembolic risk and high contraceptive effectiveness of NOMAC-E2 and COCLNG. SHORT CONDENSATION: This subgroup analysis of the PRO-E2 study provides comprehensive epidemiological data on the use of combined oral contraceptives in a large Italian cohort, with a higher prevalence of women over 35 years and smokers. The study confirms the low thromboembolic risk and high contraceptive effectiveness of NOMAC-E2 pill.

NOMAC-E2 compares to LNG combined oral contraceptives in women over forty: real-world PRO-E2 study.

OBJECTIVE: To investigate safety and effectiveness of NOMAC-E2 and levonorgestrel-containing COCs (COCLNG) in users over 40. METHODS: In this large, observational study, new users1 of NOMAC-E2 and COCLNG were recruited in Europe, Australia, and Latin America and followed-up via questionnaires. Incidence of venous thromboembolism (VTE) was expressed as incidence rate (IR; events/104 women-years [WY]). Unintended pregnancy was expressed by the Pearl Index (PI; contraceptive failures/100 WY). Mood and weight changes were defined as mean changes in mood score and percentage of body weight. RESULTS: Overall, 7,762 NOMAC-E2 and 6,059 COCLNG users over 40 were followed-up. NOMAC-E2 showed no increased VTE risk compared to COCLNG; confirmed events: 5 NOMAC-E2 (IR 5.9; 95% CI, 1.9-13.7) vs 4 COCLNG (IR 5.9; 95% CI, 1.6-15.1). Unintended pregnancy did not differ substantially between cohorts; confirmed events: 4 NOMAC-E2 (PI 0.05; 95% CI, 0.01-0.13) vs 5 COCLNG (PI 0.08; 95% CI, 0.03-0.18). No differential effect on mood and weight was observed between cohorts. CONCLUSIONS: NOMAC-E2 can be considered a valid alternative to COCLNG in perimenopausal women.

NOMAC-E2 shows a better contraceptive effectiveness than LNG combined oral contraceptives in women under 25: real-world PRO-E2 study.

Objective: To investigate unintended pregnancy and changes in mood, acne, and weight in NOMAC-E2 vs levonorgestrel-containing COC (COCLNG) users under 25 years.Methods: In this large, observational study, new users (first-ever users of an eligible COC or restarting with the same or a new eligible COC after a break of at least 2 months) of NOMAC-E2 and COCLNG were recruited in 12 countries in Europe, Australia, and Latin America and followed up via questionnaires for up to 2 years. Unintended pregnancy was expressed by the Pearl Index (PI; contraceptive failures/100 women-years). Crude (HRcrude) and adjusted hazard ratios (HRadj) were calculated. Mood and acne changes were defined as change of score from baseline. Weight change was defined as percent change of body weight.Results: Overall, 12,829 NOMAC-E2 users and 17,095 COCLNG users under 25 were followed-up. The risk of unintended pregnancy was statistically significantly lower in the NOMAC-E2 cohort; confirmed events: 30 NOMAC-E2 (PI 0.24; 95% CI, 0.16-0.35) vs 94 COCLNG (PI 0.51; 95% CI, 0.41-0.62). The HRcrude for unintended pregnancy comparing NOMAC-E2 to COCLNG was 0.47 (95% CI, 0.31-0.71) and the HRadj was 0.52 (95% CI, 0.34-0.78). No differential effect on acne, mood, and weight was observed between cohorts.Conclusions: NOMAC-E2 shows a significantly better contraceptive effectiveness in young women and has no differential effect on acne, mood, and weight compared to COCLNG.

Efficacy and Safety of Megestrol in the Hospitalized Older Person.

Objectives To evaluate the efficacy and safety of megestrol for off-label use in older patients with weight loss. Design Retrospective, nonblinded cohort study. Setting Upstate University Hospital is a 420-bed facility and academic medical center with a level 1 trauma center. Upstate Community Hospital is a 314-bed acute care/hospital/ambulatory care center and long-term care hospital that also provides teaching services. Participants Patients 65 years of age and older without malignancy or acquired immunodeficiency syndrome who were initiated and continued megestrol therapy at the Upstate University hospitals for at least two weeks were included. Of the 1,290 patients initially screened, 16 patients on megestrol were evaluated. An age- and gender-matched control group of 16 patients was utilized for comparison of changes in weight and other variables. Interventions Patients in the megestrol group have received daily doses of megestrol between 160 mg to 800 mg for an average duration of 19 days. Patients in the control group had no history or current use of megestrol utilization. Main Outcome Measurements The primary outcome was an increase in weight. Secondary outcome measures included albumin and thromboembolic events. Changes in weight and albumin were also compared with the control group. Results At a mean duration of 19 days, there was no significant difference in weight gain (0.95 kg, OR = 1.33 [95% CI -1.615-3.527]). Albumin decreased by (0.4 g/dL OR = 0.916 [95% CI 0.12-0.78]) and none of the patients developed a thromboembolic event. Conclusion In older hospitalized patients, megestrol did not increase weight, and did not improve albumin. No thromboembolic events were observed, but this may be because of a limited duration of observation of therapy and the routine use of anticoagulation prophylaxis in the inpatient setting.

Randomized study on the effectiveness of nomegestrol acetate plus 17ß-estradiol oral contraceptive versus dienogest oral pill in women with suspected endometriosis­associated chronic pelvic pain.

BACKGROUND: To evaluate the effects of a combined oral contraceptive containing 1.5 mg 17b-estradiol (E2) and 2.5 mg nomegestrol acetate (NOMAC) or 2 mg/daily dienogest (DNG) oral progestin on endometriosis-associated chronic pelvic pain (CPP) and on the quality of life (QoL) and sexual function, by a randomized study design. METHODS: The E2/NOMAC group and DNG group included 99 and 98 women, respectively. The levels of CPP were measured by the visual analogic scale (VAS). The QoL scores were investigated by the Short Form-36 questionnaire (SF-36). Finally, sexual function was studied using the Female Sexual Function Index (FSFI), while sexual distress was studied by the Female Sexual Distress Scale (FSDS). The study had 3, 6 and 12-month follow-ups. RESULTS: The intra-group analysis showed an improvement of the VAS score from baseline to the 12-month follow-up in the women of both groups (p < 0.001). The inter-group comparison showed a similar improvement of CPP (p = 0.06). Women on DNG had better SF-36 somatic (p < 0.01) and FSFI scores (p < 0.006) than women on E2/NOMAC at the 6- and 12-month follow-ups. CONCLUSIONS: The results support the efficacy of both hormonal treatments, even if DNG was more effective than E2/NOMAC in a limited intergroup comparison.

Pilot Data on the Feasibility And Clinical Outcomes of a Nomegestrol Acetate Oral Contraceptive Pill in Women With Premenstrual Dysphoric Disorder.

Background: Up to 80% of reproductive-aged women experience premenstrual symptoms. Premenstrual Dysphoric Disorder (PMDD) is a severe form, affecting 2-5% of women. Combined oral contraceptive pills (COCPs) are used in the treatment of PMDD. Clinical practice suggests that a newer COCP containing nomegestrol acetate (2.5mg) and 17-beta estradiol (1.5mg), may be a suitable treatment for mood symptoms in PMDD. Materials and Methods: This was a clinical follow-up feasibility study of women who had attended the Monash Alfred Psychiatry research centre, Women's Mental Health Clinic, with a diagnosis of PMDD. 67% of the sample also had concurrent cPTSD, 29% co-morbid anxiety, and 20% depression. They were recommended treatment with nomegestrol acetate/17-beta estradiol. Eligible women were contacted by telephone to answer a questionnaire to assess women's subjective response to nomegestrol acetate/17-beta estradiol, acceptability and the Depression, Anxiety and Stress Scale-21 (DASS-21) after being recommended nomegestrol acetate/17-beta estradiol. The paired-sample t-test was used to determine if there were any statistically significant differences in the DASS-21 scores over the study observation period (before and after taking nomegestrol acetate/17-beta estradiol). Results: 35 (74.5%) women reported a subjective positive mood response to nomegestrol acetate/17-beta estradiol, 31 (63.3%) adhered to the medication, and only 10 (20.4%) women reported side effects as the main reason for discontinuing nomegestrol acetate/17-beta estradiol. There were statistically significant reductions (p<0.05) in the overall DASS-21 scores from before women commenced nomegestrol acetate/17-beta estradiol and after commencement of treatment. Conclusions: This preliminary study supports the acceptability and effectiveness of nomegestrol acetate/17-beta estradiol as a treatment for mood symptoms in PMDD. Further research, particularly a randomized controlled trial, is required to elucidate the effect of nomegestrol acetate/17-beta estradiol treatment on mood in PMDD.

Prospective controlled cohort study on the safety of a monophasic oral contraceptive containing nomegestrol acetate (2.5mg) and 17ß-oestradiol (1.5mg) (PRO-E2 study): risk of venous and arterial thromboembolism.

OBJECTIVE: To assess and compare the risk of venous thromboembolism (VTE) and arterial thromboembolism (ATE) in NOMAC-E2 users with levonorgestrel-containing combined oral contraceptive (COCLNG) users. STUDY DESIGN: This large, prospective, observational active surveillance study used a non-inferiority design. New users of NOMAC-E2 and COCLNG were recruited in 12 countries in Australia, Europe, and Latin America. Women were followed up directly and self-reported outcomes of interest were validated via treating physicians. The main outcome of interest was VTE, specifically deep venous thrombosis of the lower extremities (DVT) and pulmonary embolism (PE). Secondary outcomes included all VTE and ATE. Data on confounders were captured and independent blinded adjudication assessed the classification of events. Incidence rates, crude (HRcrude), and adjusted (HRadj) hazard ratios were calculated. RESULTS: A total of 101,498 women (49,598 NOMAC-E2 users and 51,900 COCLNG users) were enrolled and followed for up to 2 years (144,901 WY of observation). NOMAC-E2 users had a higher mean age (31.0 ± 8.63 years) than COCLNG users (29.3 ± 8.53 years) but other baseline characteristics were similar between the cohorts. The main analysis comparing the risk of DVT of the lower extremities and PE in NOMAC-E2 users versus COCLNG users yielded an HRadj of 0.59 (95% CI, 0.25-1.35) (adjusted for age, BMI, family history of VTE, and current duration of use). The risk of all VTE and ATE was not higher in NOMAC-E2 users compared with COCLNG users. CONCLUSION(S): NOMAC-E2 use was not associated with a higher risk of VTE or ATE compared with COCLNG.

Unintended pregnancy in users of nomegestrol acetate and 17ß-oestradiol (NOMAC-E2) compared with levonorgestrel-containing combined oral contraceptives: final results from the PRO-E2 study.

OBJECTIVE: To assess and compare the risk of unintended pregnancy in NOMAC-E2 users with levonorgestrel-containing COC (COCLNG) users in clinical practice. STUDY DESIGN: In this observational study, new users1 of NOMAC-E2 and COCLNG were recruited in Europe, Australia, and Latin America and followed for up to 2 years. Unintended pregnancy was expressed by the Pearl Index (contraceptive failures per 100 women-years [WY]), crude hazard ratios (HRcrude) and adjusted hazard ratios (HRadj). RESULTS: Overall, 44,559 and 46,754 users were recruited to the NOMAC-E2 and COCLNG user cohorts, respectively. There were 64 unintended pregnancies in NOMAC-E2 users (0.15 per 100 WY; 95% CI, 0.11-0.19) and 200 in COCLNG users (0.41 per 100 WY; 95% CI, 0.35-0.47). The unintended pregnancy risk was statistically significantly lower in the NOMAC-E2 cohort (p<.0001) compared to the COCLNG user cohort. The HRadj of NOMAC-E2 vs COCLNG was 0.45 (95% CI, 0.34-0.60; adjusted for age, body mass index, gravidity, COC user status, education level). CONCLUSIONS: NOMAC-E2 demonstrated superior contraceptive effectiveness compared to COCLNG, likely due to the comparatively short hormone-free interval and possibly reinforced by the long half-life of NOMAC.

Preliminary report of patients with meningiomas exposed to Cyproterone Acetate, Nomegestrol Acetate and Chlormadinone Acetate - Monocentric ongoing study on progestin related meningiomas.

INTRODUCTION: The relationship between meningioma and progestins has not been elucidated. Meningioma regression after acetate cyproterone (CA) withdrawal has been reported. Our purpose was to evaluate the meningioma evolution after withdrawal of progestins in patients who underwent long-term exposure to CA, nomegestrol acetate (NA), chlormadinone acetate (ChlA). METHODS: Our study retrospectively included 69 patients with intracranial meningioma and exposed to one of these 3 progestins between December 2006 and March 2019. In each patient, clinico-radiological (MRI) follow-up was performed every 6 months after diagnosis and treatment withdrawal recommendation. Statistical analyses were applied to compare tumor location and respect of prescription rules between the 3 groups. RESULTS: The mean hormonal exposure was 16 years in CA group (n = 46), 16 years in NA group (n = 12) and 9.7 years in ChlA group (n = 11). A higher rate of "out of label" use was observed in the CA group (p = 0.003). Multiple meningiomas were demonstrated in more than 60% of cases in each group. Anterior skull base location was noted in 60.5% of cases in CA group, 25% of cases in NA group and 36.7% of cases in ChlA group (p = 0.05). Incomplete tumor regression was recorded in 11 cases of CA group and in 2 cases of ChlA group. CONCLUSION: In CA group, our results suggest a strong relationship between this treatment and development of intracranial meningioma. In presence of voluminous asymptomatic meningioma, treatment can be delayed due to the potential regression after withdrawal. On the contrary in NA and ChlA groups, further studies are needed.

Clinical Use of Progestins and Their Mechanisms of Action: Present and Future (Review).

This review summarizes the current opinions on the mechanisms of action of nuclear, mitochondrial, and membrane progesterone receptors. The main aspects of the pharmacological action of progestins have been studied. Data on the clinical use of gestagens by nosological groups are presented. Particular attention is paid to progesterone, megestrol acetate, medroxyprogesterone acetate due to broadening of their spectrum of action. The possibilities of using gestagens as neuroprotectors, immunomodulators, and chemosensitizers are considered.

Megestrol acetate drives endometrial carcinoma cell senescence via interacting with progesterone receptor B/FOXO1 axis.

Megestrol acetate is a common and efficient anticancer progesterone. To explore the activity and the therapeutic mechanisms of megestrol acetate in endometrial cancer, human endometrial cancer cell lines Ishikawa and HHUA overexpressing progesterone receptor A (PR-A) and progesterone receptor B (PR-B) were treated with megestrol acetate. Cell viability, apoptosis, cycle arrest, and senescence, as well as the expressions of p21 and p16, two hallmarks of cellular senescence, were evaluated. Compared with the control, >10 nmol/L megestrol acetate treatment could significantly reduce endometrial cancer cell growth, and induce the irreversible G1 arrest and cell senescence. The expression of cyclin D1 in megestrol acetate treated cells was downregulated, while the expressions of p21 and p16 were upregulated via PR-B isoform. FOXO1 inhibitor AS1842856 could significantly abrogate megestrol acetate-induced cell senescence, suggesting that FOXO1 was involved in megestrol acetate/PR-B axis. These findings may provide a new understanding for the treatment of human endometrial cancer.

Estradiol/nomegestrol acetate as a first-line and rescue therapy for the treatment of ovarian and deep infiltrating endometriosis.

PURPOSE: Estradiol valerate/nomegestrol acetate (E2V/NOMAC) is a new combined oral contraceptive with a good tolerability profile and low drop-out rates, which was shown to improve menstrual-related symptoms. This study aims to evaluate its effectiveness in the control of symptoms and progression of disease in women with ovarian endomestriomas and deep infiltrating endometriosis (DIE). METHODS: This was a retrospective cohort study on 39 women with pelvic endometriosis treated with E2V/NOMAC. We assessed for each patient, at the beginning of treatment and after 6 months, the painful symptoms, through a global VAS (Visual Analogue Scale) index and the size of the greatest ovarian and/or deep infiltrating endometriotic lesions. RESULTS: After 6 months of treatment, a significant reduction was observed for the global VAS score for pain symptoms and for the mean size of ovarian endometriomas, whereas DIE lesions did not present significant changes in mean size. CONCLUSIONS: E2/NOMAC was effective in reducing pain symptoms associated with pelvic endometriosis and the size of ovarian endometriomas, whereas DIE lesions remained stable. This therapy could provide good results in the control of symptoms and disease progression in women with pelvic endometriosis.

Sustained growth of intraosseous hormone-associated meningiomas after cessation of progestin therapy.

Hormone-associated meningiomas tend to stop growing or decrease in size after cessation of certain progestins, mainly cyproterone acetate. We report three observations on the natural history of hormone-associated intraosseous meningiomas, showing in a first patient that those tumors may grow rapidly under nomegestrol. We then demonstrate the sustained growth of intraosseous hormone-associated meningiomas after cessation of promesgestone and nomegestrol, independently of the intracranial portion, which concurrently decreased in size in the second case or was resected at the time of nomegestrol withdrawal in the third case, thus giving new insights into the tumorigenesis mechanisms of hormone-associated intraosseous meningiomas.

iKanEat: protocol for a randomized controlled trial of megestrol as a component of a pediatric tube weaning protocol.

BACKGROUND: Although tube feeding routinely saves the lives of children who do not eat by mouth, chronic tube feeding can be a burden to patients, caregivers, and families. Very few randomized trials exist regarding the best methods for weaning children from their feeding tubes. METHODS: The current paper describes a randomized controlled trial of an empirically supported outpatient treatment protocol for moving children from tube to oral eating called iKanEat. Specifically, we describe the methods of randomized double-blind, placebo-controlled trial which includes a 4-week course of megestrol, the only medication used in the iKanEat protocol, to determine whether the addition of megestrol results in improved child outcomes. The primary and secondary aims are to assess the safety and efficacy of megestrol as part of the iKanEat protocol. The third aim is to provide critical information about the impact of the transition from tube to oral feeding on parent stress and parent and child quality of life. DISCUSSION: This trial will provide data regarding whether megestrol is a safe and effective component of the iKanEat tube weaning protocol, as well as important data on how the tube weaning process impacts parent stress and parent and child quality of life. TRIAL REGISTRATION: ClinicalTrials.gov NCT#03815019 . Registered on January 17, 2019.

Oral nomegestrol acetate and transdermal 17-beta-estradiol for preventing post-partum relapses in multiple sclerosis: The POPARTMUS study.

BACKGROUND: Sex steroids could explain the course of multiple sclerosis (MS) in pregnancy. OBJECTIVE: To compare the annualized relapse rate (ARR) 12 weeks post-partum in women treated with nomegestrol acetate (NOMAc) and 17-beta-estradiol (E2) versus placebo. METHODS: POPARTMUS is a randomized, proof-of-concept trial in women with MS, receiving oral NOMAc 10 mg/day and transdermal estradiol 75 µg/week, or placebo. RESULTS: Recruitment was stopped prematurely due to slow inclusions (n = 202). No treatment effect was observed on ARR after 12 weeks (sex steroids = 0.90 (0.58-1.39), placebo = 0.97 (0.63-1.50) (p = 0.79)). CONCLUSION: POPARTMUS failed showing efficacy of a NOMAc-E2 combination in preventing post-partum relapses.
