  • Other Data Relevant to an Evaluation of Carcinogenicity and Its Mechanisms
    COMBINED ESTROGEN−PROGESTOGEN CONTRACEPTIVES 143 4. Other Data Relevant to an Evaluation of Carcinogenicity and its Mechanisms 4.1 Absorption, distribution, metabolism and excretion in humans The metabolism and disposition of various formulations of oral contraceptives used in humans differ. After entering the small intestine, estrogenic and progestogenic compounds in combined oral contraceptives undergo metabolism by bacterial enzymes and enzymes in the intestinal mucosa to varying extents. The mixture of metabolized and unmetabolized compounds then undergoes intestinal absorption, and thus enters the portal vein blood, which perfuses the liver. In the liver, the compounds can be metabolized extensively, which leads to variations in the amount of active drug. A fraction of the absorbed dose of ethinyl- estradiol and some progestogens is also excreted in the bile during its first transit through the liver. Although some of these compounds are partially reabsorbed via the enterohepatic circulation, a fraction may also be excreted in this ‘first pass’, which reduces overall bio- availability. Since steroids penetrate normal skin easily, various systems have also been developed that deliver estrogens and progestogens parenterally, e.g. transdermal patches, nasal sprays, subcutaneous implants, vaginal rings and intrauterine devices (Fanchin et al., 1997; Dezarnaulds & Fraser, 2002; Meirik et al., 2003; Sarkar, 2003; Wildemeersch et al., 2003; Sturdee et al., 2004). These different modes of administration have been described previously (IARC, 1999). In general, all parenteral routes avoid loss of the drug by hepatic first-pass metabolism and minimally affect hepatic protein metabolism. The absorption rates of orally administered estrogens and progestogens are usually rapid; peak serum values are observed between 0.5 and 4 h after intake.

  • The Realization of New Medical Alternatives to Surgery for Endometriosis
    Paradigm Shift: The Realization of New Medical Alternatives to Surgery for Endometriosis Edward M. Lichten, MD* ©2016, Edward M. Lichten, MD Journal Compilation ©2016, AARM DOI 10.14200/jrm.2016.5.0099 ABSTRACT Endometriosis is one of the most destructive benign diseases of women. It is established as developing and being present in upward of 70% of adolescents who do not experience relief of menstrual pain with use of oral contraceptives and anti- inflammatory drugs. It occurs in 8%–10% of women in the United States and is most prevalent in developed countries. Symptoms of endometriosis include disabling pain, hemorrhagic uterine bleeding, and infertility. Women with disease can expect a 12% hysterectomy rate. While present medical therapy may offer relief of many symptoms, there have been no major new directions in pharmacologic therapy since leuprolide acetate was made available in 1977. Danazol remains the only alternative to GnRH agonists with proven efficacy and reasonable side effects, according to Cochrane Reviews, yet, it is underused, and GnRH agonists are favored even when Danazol in combination seems more effective. A previously published case report on use of the combination of nandrolone and stanozolol to treat a young woman scheduled for hemicolectomy is discussed as an alternative to surgery along with the limits of standard therapy. This review will focus on recent research and theories seeking to establish causation for disease and offer treatment recommendations. Keywords: Endometriosis; Environmental toxins; Xenoestrogens;

  • Metformin Enhances Nomegestrol Acetate Suppressing Growth of Endometrial Cancer Cells and May Correlate to Downregulating Mtor Activity in Vitro and in Vivo
    International Journal of Molecular Sciences Article Metformin Enhances Nomegestrol Acetate Suppressing Growth of Endometrial Cancer Cells and May Correlate to Downregulating mTOR Activity In Vitro and In Vivo Can Cao 1,2, Jie-yun Zhou 2, Shu-wu Xie 2, Xiang-jie Guo 2, Guo-ting Li 2, Yi-juan Gong 2, Wen-jie Yang 2, Zhao Li 2, Rui-hua Zhong 2, Hai-hao Shao 2 and Yan Zhu 2,* 1 Pharmacy School, Fudan University, Shanghai 200032, China 2 Lab of Reproductive Pharmacology, NHC Key Lab of Reproduction Regulation, Shanghai Institute of Planned Parenthood Research, Fudan University, Shanghai 200032, China * Correspondence: [email protected]; Tel.: +86-21-6443-8416 Received: 11 June 2019; Accepted: 3 July 2019; Published: 5 July 2019 Abstract: This study investigated the effect of a novel progestin and its combination with metformin on the growth of endometrial cancer (EC) cells. Inhibitory effects of four progestins, including nomegestrol acetate (NOMAC), medroxyprogesterone acetate, levonorgestrel, and cyproterone acetate, were evaluated in RL95-2, HEC-1A, and KLE cells using cell counting kit-8 assay. Flow cytometry was performed to detect cell cycle and apoptosis. The activity of Akt (protein kinase B), mTOR (mammalian target of rapamycin) and its downstream substrates 4EBP1 (4E-binding protein 1) and eIF4G (Eukaryotic translation initiation factor 4G) were assayed by Western blotting. Nude mice were used to assess antitumor effects in vivo. NOMAC inhibited the growth of RL95-2 and HEC-1A cells, accompanied by arresting the cell cycle at G0/G1 phase, inducing apoptosis, and markedly down-regulating the level of phosphorylated mTOR/4EBP1/eIF4G in both cell lines (p < 0.05).

  • Combined Hormonal Influence of Cyproterone Acetate and Nomegestrol Acetate on Meningioma: a Case Report
    Acta Neurochirurgica (2019) 161:589–592 https://doi.org/10.1007/s00701-018-03782-4 CASE REPORT - TUMOR - MENINGIOMA Combined hormonal influence of cyproterone acetate and nomegestrol acetate on meningioma: a case report Pierre-Olivier Champagne1,2 & Thibault Passeri1 & Sebastien Froelich1 Received: 7 November 2018 /Accepted: 18 December 2018 /Published online: 22 January 2019 # Springer-Verlag GmbH Austria, part of Springer Nature 2019 Abstract Cyproterone acetate (CPA) is an antiandrogenic drug which has recently been recognized to promote the occurrence and growth of intracranial meningiomas. Nomegestrol acetate (NOMAC) is a widely used progestin-like drug that could be suggested as an alternative for patients taking CPA. We report a case of CPA-related meningioma for which relay from CPA to NOMAC led to further tumor growth and cessation of NOMAC-induced tumor shrinkage. We suggest NOMAC can have a similar effect than CPA on meningiomas. The use of NOMAC as replacement for CPA in the presence of a meningioma should be discouraged until further evidence becomes available on the role of NOMAC in such instances. Keywords Cyproterone acetate . Nomegestrol acetate . Meningioma . Hormone therapy Introduction relay with NOMAC led to new tumor progression. The impli- cations of meningioma growth with NOMAC are discussed. The relationship between sex hormones and meningioma oc- currence or growth has been shown by various clinical and in vitro studies [1, 2]. Cyproterone acetate (CPA) is a Case report progestin-like drug with a strong antiandrogenic effect that is currently emerging as one of the first drug able to clearly induce meningioma growth clinically [3]. Cessation of CPA A 46-year-old woman with no relevant past medical histo- can lead in many cases to tumor regression.

  • The Selective Estrogen Enzyme Modulators in Breast Cancer: a Review
    Biochimica et Biophysica Acta 1654 (2004) 123–143 www.bba-direct.com Review The selective estrogen enzyme modulators in breast cancer: a review Jorge R. Pasqualini* Hormones and Cancer Research Unit, Institut de Pue´riculture, 26 Boulevard Brune, 75014 Paris, France Received 21 January 2004; accepted 12 March 2004 Available online 15 April 2004 Abstract It is well established that increased exposure to estradiol (E2) is an important risk factor for the genesis and evolution of breast tumors, most of which (approximately 95–97%) in their early stage are estrogen-sensitive. However, two thirds of breast cancers occur during the postmenopausal period when the ovaries have ceased to be functional. Despite the low levels of circulating estrogens, the tissular concentrations of these hormones are significantly higher than those found in the plasma or in the area of the breast considered as normal tissue, suggesting a specific tumoral biosynthesis and accumulation of these hormones. Several factors could be implicated in this process, including higher uptake of steroids from plasma and local formation of the potent E2 by the breast cancer tissue itself. This information extends the concept of ‘intracrinology’ where a hormone can have its biological response in the same organ where it is produced. There is substantial information that mammary cancer tissue contains all the enzymes responsible for the local biosynthesis of E2 from circulating precursors. Two principal pathways are implicated in the last steps of E2 formation in breast cancer tissues: the ‘aromatase pathway’ which transforms androgens into estrogens, and the ‘sulfatase pathway’ which converts estrone sulfate (E1S) into E1 by the estrone-sulfatase.

  • PRAC Recommendations on Signals October 2018
    29 October 20181 EMA/PRAC/689235/2018 Pharmacovigilance Risk Assessment Committee (PRAC) PRAC recommendations on signals Adopted at the 1-4 October 2018 PRAC meeting This document provides an overview of the recommendations adopted by the Pharmacovigilance Risk Assessment Committee (PRAC) on the signals discussed during the meeting of 1-4 October 2018 (including the signal European Pharmacovigilance Issues Tracking Tool [EPITT]2 reference numbers). PRAC recommendations to provide supplementary information are directly actionable by the concerned marketing authorisation holders (MAHs). PRAC recommendations for regulatory action (e.g. amendment of the product information) are submitted to the Committee for Medicinal Products for Human Use (CHMP) for endorsement when the signal concerns Centrally Authorised Products (CAPs), and to the Co-ordination Group for Mutual Recognition and Decentralised Procedures – Human (CMDh) for information in the case of Nationally Authorised Products (NAPs). Thereafter, MAHs are expected to take action according to the PRAC recommendations. When appropriate, the PRAC may also recommend the conduct of additional analyses by the Agency or Member States. MAHs are reminded that in line with Article 16(3) of Regulation No (EU) 726/2004 and Article 23(3) of Directive 2001/83/EC, they shall ensure that their product information is kept up to date with the current scientific knowledge including the conclusions of the assessment and recommendations published on the European Medicines Agency (EMA) website (currently acting as the EU medicines webportal). For CAPs, at the time of publication, PRAC recommendations for update of product information have been agreed by the CHMP at their plenary meeting (17-20 October 2018) and corresponding variations will be assessed by the CHMP.

  • Zoely, INN-Nomegestrol Acetate / Estradiol
    EMA/216210/2016 EMEA/H/C/001213 EPAR summary for the public Zoely nomegestrol acetate / estradiol This is a summary of the European public assessment report (EPAR) for Zoely. It explains how the Committee for Medicinal Products for Human Use (CHMP) assessed the medicine to reach its opinion in favour of granting a marketing authorisation and its recommendations on the conditions of use for Zoely. What is Zoely? Zoely is a medicine available as 24 white ‘active’ tablets that contain the active substances nomegestrol acetate (2.5 mg) and estradiol (1.5 mg), and four yellow ‘inactive’ (placebo) tablets that do not contain any active substance. What is Zoely used for? Zoely is a contraceptive pill. The medicine can only be obtained with a prescription. How is Zoely used? One tablet a day is taken for as long as contraception is required, starting with an active tablet on the first day of the cycle. Zoely comes in blisters containing 28 tablets (24 white tablets followed by 4 yellow tablets), which are taken in sequence using stickers to identify the days of the week for each tablet. How does Zoely work? Zoely is a combined contraceptive pill that contains two active substances, nomegestrol acetate (a progestogen) and estradiol (an oestrogen). Estradiol is the same as a hormone naturally produced by the ovaries during a menstrual cycle. Nomegestrol acetate is derived from the hormone called progesterone which is also produced by the ovaries during a menstrual cycle. Zoely works by changing 30 Churchill Place ● Canary Wharf ● London E14 5EU ● United Kingdom Telephone +44 (0)20 3660 6000 Facsimile +44 (0)20 3660 5555 Send a question via our website www.ema.europa.eu/contact An agency of the European Union © European Medicines Agency, 2016.
