Active clinical trials for "Osteoporosis"

The human ovary produces male sex hormones (androgen) and female sex hormones (estrogen). Currently, androgen is not included in hormone replacement therapy for women with premature ovarian failure. Present hormone replacement therapy (HRT) was designed to treat women who experience ovarian failure at menopause (around the age of 50). However, 1% of women will experience premature failure of the ovaries before the age of 40. There have been no studies conducted to determine proper hormone replacement therapies for these younger women. Some research suggests that the usual menopausal hormone replacement therapy is not adequate to protect young women with premature ovarian failure from developing osteoporosis. Women with premature ovarian failure have abnormally low levels of androgens circulating in their blood. This may contribute to the increase risk for osteoporosis. This study will compare two treatment plans for women with premature ovarian failure. Treatment plan one will be physiological estrogen hormone replacement. Treatment plan two will be physiological estrogen hormone replacement plus androgen. The study will attempt to determine which plan is more beneficial to women in relation to osteoporosis and heart disease. The hormones will be contained in patches and given by placing the patches against the patient's skin. The patches were designed to deliver the same amount of hormone as would be normally produced by the ovary in young women. The success of the treatment will be measured by periodically checking the density of patient's bone in the leg (femoral neck bone) . Researchers will take an initial (baseline) measurement of bone density before beginning treatment and then once a year, for 3 additional years, during treatment. The study will also consider bone density of the spine, bone turnover, heart disease risk factors, and psychological state.

An Italian Multicentric randomized, open-label therapeutic trial evaluating the efficacy and safety of Neridronate in the treatment of Osteoporosis in patients with Thalassemia Major and Severe Thalassemia Intermedia. Efficacy and safety of the drug will be evaluated measuring at every visit this parameters: haematological: Haemochrome blood chemistry: creatinine, BUN, AST, ALT, Ca, P, proteins electrophoresis, total proteins. The prevalence of ectopic calcification and pseudoxantoma elasticum (PXE)-like syndrome and their follow-up will be evaluated at the beginning of the study vs 24 months through physical examination, abdominal echography and fundus oculi examination. During the trial other known risks factors for osteoporosis will be recorded, including prevalence and incidence of bone fractures and, if executed, Polimorphisms COLIA1. At the beginning of the study and at months 12 and 24 morphometry DXA will be performed to evaluate of the presence of bone deformities. Furthermore data regarding QOL and symptom pain will be evaluated trough administration of scale SF-36. At 12 months an intratrial analisis will be performed on efficacy and safety parameters in order to introduce possible amendments to the study design and to decide the prosecution of the trial During the trial all adverse events will be recorded

This is a three month comparison trial of standard dose parathyroid hormone (PTH) (1-34) and two different doses of Parathyroid Hormone-related Protein (PTHrP) (1-36). The investigators want to to demonstrate that daily subcutaneous injection of PTHrP (1-36) in postmenopausal women with osteoporosis stimulates bone formation to the same or greater degree than PTH (1-34) but with less bone resorption.

The purpose of this project is to determine the incidence of osteoporosis in the investigators' population of HIV-infected patients and to assess the efficacy and security of zoledronic acid, whose efficacy in post-menopausal women with high fracture risk treatment and in Paget's disease treatment has already been demonstrated.

This study will assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of once-daily multiple-dose administration of odanacatib (MK0822).

To evaluate the effect of subject knowledge of their disease status on persistence in subjects receiving Actonel 5 mg daily over a 12-month period for the prevention and treatment of GIO.

The purpose of this study is to assess the dose-response on the percent change from baseline in lumbar spine bone mineral density (BMD) at lumbar vertebrae 1 to 4 (L1- L4) when odanacatib (MK-0822) 10 mg, 25 mg, 50 mg or placebo is orally administered once weekly for 52 weeks to Japanese involutional osteoporosis participants. The study will also assess safety and tolerability of odanacatib (10, 25, and 50 mg) in these participants. The study will enroll approximately 280 participants and randomly assign them to 3 different doses of odanacatib or placebo for 52 weeks, along with supplemental vitamin D3 and calcium carbonate. The primary efficacy hypothesis is that a dose-response relationship on the percent change from baseline in lumbar spine BMD (L1- L4) is seen when odanacatib 10, 25, 50 mg or placebo is orally administered once weekly for 52 weeks to involutional osteoporosis participants. The primary safety hypothesis is that odanacatib will be safe and well tolerated over 52 weeks to involutional osteoporosis participants.

To study the effect of long-term treatment with raloxifene, compared with placebo, on the rate of new vertebral fractures in osteoporotic postmenopausal women with and without existing vertebral fractures.

The aim of this pilot study was to determine the effect of physiotherapy on impairments and health-related quality of life in people with a painful osteoporotic spinal fracture. It is hypothesised that physiotherapy will reduce impairments and improve quality of life in this patient group.

The purpose of this study is to evaluate the efficacy and safety of ONO-5334 in postmenopausal women with osteopenia or osteoporosis.
