  • Management of Women with Premature Ovarian Insufficiency
    Management of women with premature ovarian insufficiency Guideline of the European Society of Human Reproduction and Embryology POI Guideline Development Group December 2015 1 Disclaimer The European Society of Human Reproduction and Embryology (hereinafter referred to as 'ESHRE') developed the current clinical practice guideline, to provide clinical recommendations to improve the quality of healthcare delivery within the European field of human reproduction and embryology. This guideline represents the views of ESHRE, which were achieved after careful consideration of the scientific evidence available at the time of preparation. In the absence of scientific evidence on certain aspects, a consensus between the relevant ESHRE stakeholders has been obtained. The aim of clinical practice guidelines is to aid healthcare professionals in everyday clinical decisions about appropriate and effective care of their patients. However, adherence to these clinical practice guidelines does not guarantee a successful or specific outcome, nor does it establish a standard of care. Clinical practice guidelines do not override the healthcare professional's clinical judgment in diagnosis and treatment of particular patients. Ultimately, healthcare professionals must make their own clinical decisions on a case-by-case basis, using their clinical judgment, knowledge, and expertise, and taking into account the condition, circumstances, and wishes of the individual patient, in consultation with that patient and/or the guardian or carer. ESHRE makes no warranty, express or implied, regarding the clinical practice guidelines and specifically excludes any warranties of merchantability and fitness for a particular use or purpose.

Please see Table 1, which provides the latest update on the availability of all HRT products marketed in the UK and the known resupply date for products that are currently experiencing supply issues. This table also provides an update of all HRT preparations that remain available. Clinicians may be required to switch patients to alternative HRT products that contain the same active ingredients for a temporary period. Prescribing information regarding HRT equivalence to support local decision making is available through various sources such as the British National Formulary, Summary of Product Characteristics (SPC), The Monthly Index of Medical Specialities (MIMS), and other sources including local Medicines Information Centres. Clinicians are advised to work closely with community pharmacies to understand local availability of HRT products and use the table below to help make decision about appropriative HRT products for patients who are affected by the supply issues. DHSC will continue to provide updates on HRT availability in the monthly supply report, which is uploaded to the Specialist Pharmacist Services website.

  • Bazedoxifene Exhibits Antiestrogenic Activity in Animal Models of Tamoxifen-Resistant Breast Cancer: Implications for Treatment of Advanced Disease
    Published OnlineFirst March 27, 2013; DOI: 10.1158/1078-0432.CCR-12-3771 Clinical Cancer Cancer Therapy: Preclinical Research Bazedoxifene Exhibits Antiestrogenic Activity in Animal Models of Tamoxifen-Resistant Breast Cancer: Implications for Treatment of Advanced Disease Suzanne E. Wardell, Erik R. Nelson, Christina A. Chao, and Donald P. McDonnell Abstract Purpose: There is compelling evidence to suggest that drugs that function as pure estrogen receptor (ER-a) antagonists, or that downregulate the expression of ER-a, would have clinical use in the treatment of advanced tamoxifen- and aromatase-resistant breast cancer. Although such compounds are currently in development, we reasoned, based on our understanding of ER-a pharmacology, that there may already exist among the most recently developed selective estrogen receptor modulators (SERM) compounds that would have usage as breast cancer therapeutics. Thus, our objective was to identify among available SERMs those with unique pharmacologic activities and to evaluate their potential clinical use with predictive models of advanced breast cancer. Experimental Design: A validated molecular profiling technology was used to classify clinically relevant SERMs based on their impact on ER-a conformation. The functional consequences of these observed mechanistic differences on (i) gene expression, (ii) receptor stability, and (iii) activity in cellular and animal models of advanced endocrine-resistant breast cancer were assessed. Results: The high-affinity SERM bazedoxifene was shown to function as a pure ER-a antagonist in cellular models of breast cancer and effectively inhibited the growth of both tamoxifen-sensitive and -resistant breast tumor xenografts. Interestingly, bazedoxifene induced a unique conformational change in ER-a that resulted in its proteasomal degradation, although the latter activity was dispensable for its antagonist efficacy.

    Ospemifene Monograph Ospemifene (OSPHENA) National Drug Monograph October 2015 VA Pharmacy Benefits Management Services, Medical Advisory Panel, and VISN Pharmacist Executives The purpose of VA PBM Services drug monographs is to provide a comprehensive drug review for making formulary decisions. Updates will be made when new clinical data warrant additional formulary discussion. Documents will be placed in the Archive section when the information is deemed to be no longer current. FDA Approval Information Description/Mechanism of Ospemifene is a selective estrogen receptor modulator (SERM) with agonist Action actions on vaginal tissue, the endometrium and bone. Antagonist actions suggest antitumor effects in experimental breast cancer models. Ospemifene is not interchangeable with other SERMs such as raloxifene or tamoxifen, nor they with it. Indication(s) Under Review in Ospemifene is an estrogen agonist/antagonist indicated for the treatment this document (may include of moderate to severe dyspareunia, a symptom of vulvar and vaginal off label) atrophy, due to menopause. Dosage Form(s) Under Tablet (oral), 60 mg Review REMS REMS X No REMS Postmarketing Requirements See Other Considerations for additional REMS information Pregnancy Rating X Executive Summary Efficacy After 12 weeks ospemifene reduced the symptom score of dyspareunia significantly more than placebo. Thirty-eight percent of postmenopausal women taking ospemifene reported no pain upon intercourse compared to 28% taking placebo. Ospemifene significantly improved the Maturation Index (composed of percent of vaginal parabasal and superficial cells, and vaginal pH) after 12 and 52 weeks of treatment. Vaginal dryness symptom scores improved significantly more with ospemifene than placebo. Use of vaginal lubricant decreased more in women taking ospemifene than placebo.

A Dissertation Submitted to the Faculty of the Graduate School, Marquette University, in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Milwaukee, Wisconsin August 2017 ABSTRACT DESIGN AND SYNTHESIS OF SELECTIVE ESTROGEN RECEPTOR β AGONISTS AND THEIR PHARMACOLOGY K. L. Iresha Sampathi Perera, B.Sc. (Hons), M.Sc. Marquette University, 2017 Estrogens (17β-estradiol, E2) have garnered considerable attention in influencing cognitive process in relation to phases of the menstrual cycle, aging and menopausal symptoms. However, hormone replacement therapy can have deleterious effects leading to breast and endometrial cancer, predominantly mediated by estrogen receptor-alpha (ERα) the major isoform present in the mammary gland and uterus. Further evidence supports a dominant role of estrogen receptor-beta (ERβ) for improved cognitive effects such as enhanced hippocampal signaling and memory consolidation via estrogen activated signaling cascades. Creation of the ERβ selective ligands is challenging due to high structural similarity of both receptors. Thus far, several ERβ selective agonists have been developed, however, none of these have made it to clinical use due to their lower selectivity or considerable side effects.
