NCT00877097 ↗ Effects of Continuous Combined Hormone Replacement Therapy and Clodronate on Bone Mineral Density (BMD) in Osteoporotic Women Completed Kuopio University Hospital N/A 1996-07-01 Recent studies suggest that the combination of two inhibitors of bone resorption may induce a greater increase in bone mineral density (BMD) than either agent alone. In this 5-year partly randomized study the investigators examined the effects of hormone therapy (HT) with or without bisphosphonate on BMD on osteoporotic women. In the Kuopio Osteoporosis Study (OSTPRE) a population based sample of 3200 women were selected for BMD measurement by Lunar DPX in 1995-1997. In all 167 women aged 61±2.7 years (11±4.9 years postmenopausal), and the T-score < -2.5 SD at either the lumbar spine or femoral neck were recruited for this sub-study. They received daily estradiol hemihydrate (E2) 2mg + norethisterone acetate (NETA) 1mg (Kliogest®, Novo Nordisk, Denmark) and were randomized to get additional Boneplac, which consisted of either 800mg clodronate (Bonefos®, Leiras Ltd, Finland) (n=55, KB-group) or placebo (n=55, K-group). In case of contraindications or refusal from HT, the women were offered clodronate 800 mg/day (n=57, B-group) to be taken to empty stomach with a glass of water 30 minutes to two hours before breakfast. BMD was measured at time intervals 0, 1, 3 and 5-years. All repeated BMD values were interviewed by one investigator and primarily the vertebrae L2-L4 were followed. In case of spinal deformities during the study (38.3%) other lumbar levels were followed. The baseline BMD values (lumbar spine BMD 0.839±0.072 g/cm², femoral neck BMD 0.759±0.094g/cm²) were similar between the groups.
NCT00913926 ↗ Effects of Wellnara on Climacteric Symptoms Completed Bayer 2007-09-01 Aim of this NIS is to obtain further information on efficacy, tolerability, and acceptance of Wellnara in a large user population under the conditions of routine medical practice. Furthermore, any adverse drug reactions will be recorded in a large user population under the conditions of medical routine. To investigate the efficacy of Wellnara, patients will fill in a questionnaire, the so-called Menopause Rating Scale (MRS II). Further, the effects of treatment on skin and hair will be evaluated by the investigator. Patients will assess treatment effects on their sexual life. Safety parameters include monitoring of vaginal bleeding, measurement of blood pressure and body weight, and - as far as routinely used in the practice - calculation of waist-hip-ratio. Any relevant additional information related to adverse drug reactions will also be documented.
NCT03077555 ↗ Ovulation and Follicular Development Associated With Mid Follicular Phase Initiation of Combined Hormonal Contraception Completed Mahidol University Phase 4 2017-01-21 Quick starting combined oral contraception containing estradiol hemihydrate/nomegestrol acetate is effective to inhibit ovulation in healthy reproductive age women and non-inferiority to combined oral contraception containing ethinyl estradiol/gestodene.
NCT04021017 ↗ PRE-GAiN Bone Health Pilot Study Recruiting Jim Pattison Children's Hospital Foundation Phase 1 2020-01-21 This study will assess the affects of an estradiol hemihydrate transdermal system on bone health in 24 adolescent females aged 12-19 years old with anorexia nervosa. Participants in this study will be randomized 1:1 into 2 groups. One group will receive treatment with a transdermal estrogen patch and the other group will not.
NCT04021017 ↗ PRE-GAiN Bone Health Pilot Study Recruiting University of Saskatchewan Phase 1 2020-01-21 This study will assess the affects of an estradiol hemihydrate transdermal system on bone health in 24 adolescent females aged 12-19 years old with anorexia nervosa. Participants in this study will be randomized 1:1 into 2 groups. One group will receive treatment with a transdermal estrogen patch and the other group will not.
NCT06396390 ↗ Comparison of Progestin Primed Ovarian Stimulation (PPOS) vs.GnRH Antagonist Methods on IVF Outcomes NOT_YET_RECRUITING Nesta Clinic PHASE4 2024-08-01 The goal of this randomized clinical trial is to compare the effects of two different ovarian stimulation methods: Progestin Primed Ovarian Stimulation (PPOS) vs. GnRH Antagonist in embryologic outcomes of IVF Patients.
NCT06508944 ↗ Efficacy of Vaginal 17β-Estradiol on the Urinary Storage Symptoms in Postmenopausal Women COMPLETED Mahidol University PHASE4 2024-04-08 The goal of this clinical trial is to evaluate whether vaginal 17β-estradiol effectively treats storage symptoms of lower urinary tract symptoms (LUTS) and enhances quality of life. The main questions it aims to answer are: * What is the efficacy of vaginal 17β-estradiol treatment compared to placebo in alleviating storage symptoms of LUTS? * How does vaginal 17β-estradiol treatment affect the urethral maturation index and vaginal pH compared to placebo? * What impact does vaginal 17β-estradiol treatment have on overall quality of life and patients' perception of global improvement (PGI)? Participants in the trial will undergo the following procedures: * Screening procedures at the first visit to exclude correctable causes of LUTS and to complete a bladder diary. * Visit the clinic at 1-2 weeks for a review of the bladder diary and a check-up. Participants will receive the assigned dosage of vaginal 17β-estradiol or placebo: one vaginal tablet daily for two weeks, followed by one vaginal tablet twice a week for 10 weeks. * The third and fourth visits (at 4 and 12 weeks after treatment) will involve: completion of bladder diaries, questionnaires, vaginal pH testing, collection of urethral maturation index (UMI), observation of intervention's side effects and monitoring of LUTS symptoms.
