RESUMEN

OBJECTIVES: Vasomotor symptoms induced by endocrine therapy are common in breast cancer survivors and a risk factor for therapy discontinuation and lower quality of life. The REALISE study evaluated the real-world treatment landscape in breast cancer survivors with vasomotor symptoms taking endocrine therapy, including pharmaceuticals, lifestyle changes, and over-the-counter products. STUDY DESIGN: Secondary analysis of the Adelphi Vasomotor Disease Specific Programme™, a large cross-sectional point-in-time survey and chart review conducted in the US and five European countries (February-October 2020). Oncologists provided demographic, clinical, and treatment data for adult breast cancer survivors with induced vasomotor symptoms taking endocrine therapy (tamoxifen or aromatase inhibitors); patients voluntarily completed self-report surveys on their symptom severity, concomitant sleep and/or mood symptoms, lifestyle changes, and use of over-the-counter products. MAIN OUTCOME MEASURES: Patient characteristics; vasomotor symptom severity; use of pharmaceuticals, lifestyle changes, and over-the-counter products (from pre-defined lists); lines of treatment. RESULTS: Overall, 77 oncologists reported data for 618 breast cancer survivors, of whom 183 (29.6 %) completed self-report forms. Physicians classified 420 (68.0 %) women as experiencing moderate-severe vasomotor symptoms, of whom 66.9 % were receiving treatment. In total, 15.2 % of all breast cancer survivors were prescribed systemic hormone therapy. Venlafaxine (24.7 %), citalopram (16.5 %), and paroxetine (13.6 %) were the most commonly prescribed nonhormonal medications. Lifestyle changes (77.8 %) and over-the-counter products (61.6 %) were common, especially in patients with concomitant sleep and/or mood symptoms. CONCLUSIONS: Despite contraindications, a relatively large proportion of treatment-seeking breast cancer survivors with vasomotor symptoms were prescribed systemic hormone therapy. This, combined with high patient-reported use of lifestyle changes and over-the-counter products, suggests a need for symptomatic relief and demand for new nonhormonal alternatives with established safety profiles in this population.

RESUMEN

OBJECTIVE: This study aimed to examine physicians' and patients' perceptions regarding symptom burden and impact in women experiencing natural vasomotor symptoms (nVMS) or vasomotor symptoms induced by endocrine therapy for breast cancer (iVMS). METHODS: The cross-sectional survey based on real-world clinical consultations was conducted in the USA and five European countries. Obstetrician-gynecologists, primary-care physicians and oncologists provided demographic and symptom data for patients experiencing VMS; patients optionally self-reported their experiences via questionnaires, including their symptom profile and work/activity burden through the Menopause Quality of Life (MENQOL) and Work Productivity and Activity Impairment (WPAI) tools. RESULTS: Physicians completed survey forms on 2451 consulting patients; patients completed 1029 questionnaires. nVMS and iVMS severity was significantly associated with the severity of mood symptoms and sleep disturbances (p < 0.0001). However, around half of the patients with mild nVMS/iVMS also experienced moderate-severe mood changes (55.4%/43.7%) or sleep disturbances (42.4%/40.4%). Presence of mood/sleep disturbances alongside nVMS increased MENQOL vasomotor scores (p = 0.004/p < 0.001). Presence of sleep disturbances increased WPAI activity impairment (p < 0.001) but mood changes did not. Similar findings were reported for iVMS patients. CONCLUSION: Significant burden from the triad of natural or induced menopausal symptoms, sleep disturbances and mood changes affected women's daily activities, work and quality of life more than vasomotor symptoms alone.

RESUMEN

BACKGROUND: Cyproterone acetate (CPA) is a synthetic progesterone derivative introduced in the 1970s and prescribed as antiandrogenic therapy for inoperable prostate cancer, sexual deviations in men, and signs of androgenization in women. In 2020, the CPA summary of product characteristics (SmPC) was revised to include an updated special warning and precaution about (1) the risk of meningioma with increasing cumulative dose and (2) contraindication in patients with meningioma or history of meningioma. A Direct Healthcare Professional Communication (DHPC) was distributed. The European Medicine Agency's Pharmacovigilance Risk Assessment Committee requested that marketing authorization holders in Europe conduct a survey to assess physicians' knowledge of the updated key safety information. The primary objective of this study was to measure physicians' awareness (i.e., did they receive and review the revised SmPC and DHPC) and level of knowledge and understanding of the key safety information pertaining to the restricted use of CPA monotherapy because of the risk of meningioma. METHODS: This cross-sectional web-based survey was administered to dermatologists, endocrinologists, gynecologists, urologists, oncologists, psychiatrists, and general practitioners in France, Germany, Poland, Spain, and the Netherlands who had prescribed CPA monotherapy in the previous 12 months to assess awareness of the risk of meningioma associated with CPA monotherapy. RESULTS: Of the 613 physicians who participated, 85% correctly indicated that CPA monotherapy should be prescribed with the lowest effective dose, 75% correctly indicated that the risk of meningioma increases with increasing cumulative CPA monotherapy doses, and 73% correctly indicated that treatment with CPA-containing products must be stopped permanently if a patient is diagnosed with meningioma. Overall, 40% of physicians reported having received the DHPC, and 42% reported having received the revised SmPC. CONCLUSIONS: Despite low recall of receipt of the updated SmPC and DHPC, most physicians surveyed are aware of the meningioma risk and actions to mitigate the risk.

RESUMEN

Purpose: Evidence from real-world settings is important to provide an accurate picture of health care delivery. We investigated use of long-acting reversible contraception (LARC) in women aged 15-49 years.Materials and methods: Two surveys, one of women and one of health care professionals (HCPs), were conducted in parallel across seven countries. Participating women completed an online survey to assess contraceptive awareness, current method of contraception, age, and experience with current contraceptive method. HCPs participated in an online survey to provide practice-level information and three anonymous charts of hormonal LARC users.Results: Of 6903 women who completed the survey, 3225 provided information about their current primary contraception method. Overall, 16% used LARC methods, while 52% used oral contraceptives (OCs). Of hormonal intrauterine system users, 72% described their experience as 'very favourable', compared with only 53% of women using OCs. Anonymous patient records (n = 1605) were provided by 550 HCPs who completed the online survey. Most women (64%) had used short-acting reversible contraception before switching to LARC. Physicians perceived 56-84% of LARC users to be highly satisfied with their current form of contraception.Conclusions: Although usage of LARC was low, most women using LARC were highly satisfied with their method of contraception.

RESUMEN

STUDY QUESTION: Does the novel progesterone receptor (PR) modulator BAY 1002670, based on its preclinical pharmacological profile, offer a potential novel treatment option for uterine fibroids? SUMMARY ANSWER: The newly synthesized BAY1002670 has proved to be a very potent, highly selective PR modulator in all in vitro and in vivo pharmacodynamics assays performed: it exhibits marked efficacy in an innovative humanized fibroid disease model, suggesting BAY 1002670 to be a very promising treatment option for uterine fibroids. WHAT IS KNOWN ALREADY: PR inhibiting ligands have shown clinical utility in a range of potential indications and applications. Despite the emergence of the first PR antagonist >30 years ago, no agent of this compound class has been authorized in any indication for long-term application. Among other reasons, suboptimal selectivity and safety profiles of previous candidates have led to discontinuation and modification of development programmes. STUDY, DESIGN, SIZE, DURATION: The preclinical studies include relevant in vitro and in vivo assays to clarify the properties of the PR modulator BAY 1002670 as well as a fibroid xenograft study to show directly the efficacy of BAY 1002670 on the human target tissue. PARTICIPANTS/MATERIAL, SETTING, METHODS: BAY 1002670 was tested for binding and transactivational activity towards different human steroid receptors. Activity of the compound in the corresponding in vivo models (rat, rabbit) was assessed. Furthermore, BAY 1002670 was tested in a disease model for uterine fibroids utilizing primary human tumour tissues as xenograft in immunodeficient mice treated with estradiol (E2) and progesterone (P). MAIN RESULT AND THE ROLE OF CHANCE: BAY1002670 in subnanomolar concentrations exhibits a highly selective binding profile and antagonistic activity for the PR. These properties are also reflected in its action in two progesterone-dependent animal models that assess the termination of pregnancy and endometrial transformation. Favourable selectivity towards other nuclear hormone receptors was demonstrated. No in vivo activity was found at the glucocorticoid, estrogenic and mineralocorticoid receptors with only weak anti-androgenic activity. In a human fibroid xenograft model BAY 1002670 showed a marked dose-dependent reduction of fibroid tumour weight gain of 95% at a dose of 3 mg/kg/day (P < 0.005). LIMITATIONS AND REASON FOR CAUTION: Selectivity and potency of BAY 1002670 have only been determined in vitro and in animal models so far. WIDER IMPLICATIONS OF THE FINDING: The PR modulator BAY 1002670 might offer a treatment option not only for uterine fibroids but also for other gynaecological indications. STUDY FUNDING/COMPETING INTEREST: The studies took place at Bayer Pharma AG. All authors are employees of Bayer Pharma AG. No external funding declared.

RESUMEN

Carboxypeptidase Z (CPZ) is a secreted Zn-dependent enzyme whose biological function is largely unknown. CPZ has a bipartite structure consisting of an N-terminal cysteine-rich domain (CRD) and a C-terminal catalytic domain. In the early chicken embryo CPZ is initially expressed throughout the somites and subsequently becomes restricted to the sclerotome. To initiate a functional analysis of CPZ, a CPZ producing retroviral vector was applied to the presomitic mesoderm at the level of the future wing. This resulted in a loss of the scapular blade and of rostral ribs. Such dysmorphogenesis is preceded by ectopic Pax3 expression in the hypaxial part of the dermomyotome, a region from which the blade of the scapula normally derives. A mutant CPZ, lacking a critical active site glutamate, fails to induce Pax3 expression and does not cause skeletal defects. The induction of Pax3, a Wnt-responsive gene in somites, and the presence of a CRD prompted us to examine whether CPZ affects Wnt signaling. In an in vitro assay we found that CPZ, but not its inactive mutant form, enhances the Wnt-dependent induction of the homeobox gene Cdx1. In addition, immunoprecipitation experiments suggest that the CRD of CPZ acts as a binding domain for Wnt. Taken together these data provide the first evidence for CPZ playing a role in Wnt signaling.

RESUMEN

We describe the expression of Lix1 in the mouse. Starting at E8, transcripts are present in a regionalized fashion and persist throughout development. mLix1 is expressed in the cortical plate, subventricular zone, layer 5 of the postnatal cortex, the substantia nigra, dorsal root ganglia, specific nuclei of the brain stem and in spinal cord. Limb buds and facial primordia show transient expression. The prominent expression of mLix1 in the developing cerebral cortex and in the substantia nigra pars compacta makes this novel gene a candidate marker for both of these tissues.
