Active clinical trials for "Osteoporosis"

The purpose of this study is to evaluate the efficacy and safety of ONO-5920 in patients with involutional osteoporosis.

The main purpose of this study is to determine the safety and effectiveness of three week daily subcutaneous injections of Parathyroid Hormone-related Protein (1-36). Previous studies indicated that PTHrP has a skeletal 'anabolic' or bone-building effect, and has shown to increase bone mineral density in postmenopausal women with osteoporosis. Safety of PTHrP will be determined by measurements of blood pressure and pulse, serum blood calcium levels and subjective symptoms. Effectiveness will be measured by changes in measurements of blood and urine markers of bone turnover.

To compare upper GI handling of fosamax and generic, because the main AE profile of alendronate is before systemic absorption in the esophagus; differences could be relevant to the side effect profile.

This study will test the safety and efficacy of AAE581 in increasing Lumbar Spine bone mineral density (BMD) at 12 months, by Dexa-scan (DXA) in postmenopausal women with osteoporosis.

The purpose of this study is to test the safety, tolerability and effectiveness of an investigational drug and dietary supplement to reduce the risk of vitamin D insufficiency and deficiency during the treatment of osteoporosis in men and postmenopausal women.

OBJECTIVES: I. Determine the bioavailability and biologic effect of alendronate on bone metabolism in patients with cystic fibrosis. II. Assess the safety and efficacy of this treatment regimen in improving osteoporosis in this patient population.

This study will evaluate the effects of hormone replacement therapy on patients with Turner syndrome (TS)-a genetic disorder in females in which part or all of one X chromosome is missing. Most girls and women with TS have underdeveloped ovaries-the female reproductive organs that produce the female sex hormones estrogen and progesterone, and smaller amounts of the male sex hormone, testosterone. These hormones affect muscle and bone strength, sex drive, energy, and an overall sense of well being. Estrogen may also play a role in memory and mood and have a protective effect against heart disease. Women with TS have a much higher risk of developing osteoporosis (loss of bone density), high blood pressure, high cholesterol and diabetes than women without this disorder. Girls and women with Turner syndrome between the ages of 14 and 50 years may be eligible for this 2-year study. Three months before beginning treatment, all patients will wear an estrogen patch and take a progesterone tablet daily for 10 days each month. They will then be randomly assigned to one of two treatment groups to compare the effects of estrogen alone with estrogen plus testosterone on bone strength, muscle and fat mass and psychosocial well being. Both groups will wear an estrogen patch and take oral progesterone. One group will also wear a testosterone patch while the other group will wear a placebo patch (a patch that does not contain any testosterone). Neither study participants nor the doctors will know who is getting the testosterone until the study is complete. Patients will undergo the following procedures before beginning treatment and at 6, 12 and 24 months after starting treatment: Physical examination. DEXA scans (dual energy X-ray absorptiometry) to measure body composition and bone thickness. Low radiation X-rays scan the whole body to measure fat, muscle and bone mineral content.. Magnetic resonance imaging (MRI) scan of the abdomen to measure the amount of fat around the internal organs. The patient lies on a stretcher in a large tube surrounded by a magnetic field during the scanning. The procedure uses a strong magnet and radio waves to produce the images. Heel ultrasound to measure bone thickness. The heel is placed in a chamber and sound waves pass through it to produce images. Oral glucose tolerance test (OGTT) for diabetes and problems with carbohydrate metabolism. The patient drinks a sugary substance. A small amount of blood is drawn before taking the drink and four times afterwards. Blood and urine tests to measure blood counts, liver and kidney function, ovarian hormones, growth factors, thyroid function, blood lipids, bone strength markers, and to test for pregnancy. Blood pressure measurements. Psychological testing for the effect of treatment on mood, self-esteem, quality of life, social shyness, anxiety and sexual function. Neurocognitive tests (at first inpatient visit and 1 and 2 years after starting treatment) to measure nonverbal memory and visual-perceptual abilities. During the hospital admissions, patients will be given a "metabolic diet" that contains specific amounts of salt and carbohydrates to ensure accurate blood pressure and sugar metabolism measurements. Patients will keep a record of their menstrual periods and physical activity throughout the treatment period.

The purpose of this study is to assess the effect of 24 months of treatment with once daily teriparatide injection (recombinant human PTH [1-34]) 20 micrograms on bone histomorphometry and architecture. Patients will include postmenopausal, osteoporotic women who have been treated long term (at least 36 months) with alendronate, as well as postmenopausal, osteoporotic women who have never been treated for osteoporosis.

This study will evaluate the effectiveness and safety of denosumab in treating women with Postmenopausal Osteoporosis.

The purpose of this study is to assess the effects of testosterone replacement on bone density, muscle strength, physical performance, quality of life and prostate symptoms in men selected for low bone mineral density or fracture and some aspect of frailty.
