37 Clinical Trials for Various Conditions
The primary objective of this study is to determine the effect of treatment with AGA2118 versus placebo at Month 12 on lumbar spine bone mineral density (BMD) in postmenopausal women with low bone mass.
The purpose of this study is to assess if estrogen replacement normalizes urinary calcium excretion in postmenopausal women with hypercalciuria and low bone mass and to assess for differences in response to estrogen replacement in women with familial hypercalciuria compared to nonfamilial hypercalciuria.
This study examines the role of energy availability on menstrual function and bone mass in female adolescent endurance athletes. Specific evaluations include dietary intake, exercise energy expenditure, training schedules, menstrual function and bone density.
This study will evaluate whether teriparatide is superior to the active comparator in the change from baseline of lumbar spine BMD (bone mineral density) in men and postmenopausal women with low bone mass and a recent pertrochanteric hip fracture.
Decreased bone strength is a common and serious medical problem present in many women with anorexia nervosa, or disordered eating. Women with decreased bone strength are more likely to suffer broken bones than women with normal bone strength. We are investigating whether a hormone that is naturally produced by the human body -- parathyroid hormone (PTH) -- can help strengthen the bones of women with anorexia nervosa.
This study will evaluate the efficacy of acetaminophen or fluvastatin in reducing the rate of occurrence and the severity of post dose symptoms that may occur during the 3 day period following a zoledronic acid infusion in post menopausal women with low bone mass.
Osteoporosis affects millions of postmenopausal women in the USA. The current approved treatments are all drugs that prevent bone loss and possibly result in small gains in bone mass. Another possible treatment consists of drugs that increase bone formation. There are currently two drugs that stimulate bone formation, sodium fluoride and human parathyroid hormone (hPTH). Neither of these two drugs has been approved by the FDA. APOMINE has shown significant bone formation in animal studies. In this study we plan to test whether APOMINE is able to stimulate new bone formation in women with osteoporosis or low bone mass.
OBJECTIVES: I. Determine the possible causes of bone loss in premenopausal or perimenopausal women.
This was an open-label, single-center study to evaluate the usability of abaloparatide-sMTS by participants with low BMD.
This study is designed to provide information on the safety, tolerability, pharmacokinetics (PK) and bone biomarker response following multiple BPS804 administration in multiple dosing regimens. This information will permit a comparison of the possible risks and benefits of different dosing regimens of the study drug to enable optimal doses and dose intervals to be tested in subsequent studies.
The primary objectives of this study include evaluating the dose response of LY2541546 using bone mineral density (BMD) change from baseline as compared to placebo and evaluating the overall safety and tolerability of LY2541546 following multiple subcutaneous administrations in postmenopausal (PMP) women with low BMD. Following the last dose of study drug, participants will be able to participate in a 12 month extension to collect additional safety and efficacy data (no further treatment will be administered during this extension).
This study will evaluate the effect of a 1-year administration of the vitamin D analog 2-methylene-19-nor-(20S)-1alpha, 25-dihydroxyvitamin D3 (DP001) on bone mineral density (BMD), safety, and tolerability.
This study will compare the effects of Zoledronic acid and Raloxifene in reducing bone turnover markers in postmenopausal women with low bone mineral density over 6 months.
The purpose of this project is to evaluate the hypothesis that bisphosphonate treatment given to growth hormone deficient patients (regardless of current growth hormone replacement therapy status and without changing that status) significantly increases total body bone mineral density during an eighteen month period of treatment combined with calcium and Vitamin D when compared to calcium and Vitamin D treatment alone.
The purpose of this study is to examine whether daily supplementation of resveratrol would improve bone health in postmenopausal women.
To determine whether the musculoskeletal adaptations to bone-loading exercise can be significantly augmented in older women (aged 60-85) with low bone mass (osteopenia; T-scores \<-1.0 and \>-2.5) or moderate osteoporosis (T-scores \< -2.5 and \>= -3.0) and by restoring serum DHEAS to young adult levels by oral DHEA replacement.
Bone strength -the main determinant of bone fracture- is a function not only of bone mineral density (BMD) and microstructure, but also of its microenvironment, including bone marrow fat (BMF). The adrenal steroid dehydroepiandrosterone (DHEA) -the main precursor for estrogens and androgens in postmenopausal women- as well as bone-loading exercise, increase BMD in older women, however, their effects on BMF are largely unknown. This study has high potential to unveil the hormonal and mechanical effects of DHEA and exercise on BMF, respectively, and to elucidate longitudinal associations of BMF with bone strength in older women with bone loss.
No clinical trials have evaluated strontium L-lactate (SrLac), the strontium salt of the L-enantiomer of lactic acid. Therefore, this clinical study was conducted to obtain general safety and pharmacokinetic (PK) information following acute oral intakes of three doses of SrLac by healthy adults. The data provided valuable comparisons with the pharmacokinetics of other strontium salts that are in clinical use and allowed determination of the dose of SrLac that will be useful for the management of bone health.neficial for the treatment of low bone density of osteoporosis and osteopenia.
Osteoporosis is an important health problem in the rapidly-aging demographic. Fragility fractures are devastating consequences of osteoporosis. The most common treatment approach in osteoporosis is inhibition of bone resorption with drugs like alendronate (ALN). Parathyroid hormone (PTH) stimulates bone formation and is the only anabolic drug available. Dual therapy with ALN and PTH is not as effective as single-drug therapy in preventing fracture. Bone progenitor cells (MSCs) are recruited to sites of bone remodeling when a growth factor called Transforming Growth Factor Beta (TGF-β1) is released from bone. Different osteoporosis medicines may have differing effects on this process. The effects of ALN versus PTH on bone progenitor recruitment in humans are unknown. This is a randomized, clinical trial of ALN, PTH, and calcium and vitamin D in post-menopausal women with low bone mass. Women will be treated for 3 months with ALN or PTH or calcium and vitamin D. Data collected will include bone biopsies for histomorphometry and micro computed tomography (µCT), bone marrow aspirates for molecular studies, peripheral blood to detect circulating bone progenitor cells and dual X-ray absorptiometry. The investigators hypothesize that in humans, PTH will 1) increase bone progenitor number, 2) enhance recruitment of bone progenitor cells to bone resorption sites, and 3) increase bone progenitor number in peripheral circulation. Furthermore, the investigators hypothesize that ALN treatment will have the opposite effect. Understanding the differences in bone progenitor cell activity and recruitment during osteoporosis therapy will provide a mechanistic rationale for effective use of PTH and anti-resorptive drugs in osteoporosis treatment.
The purpose of this pilot study is to generate preliminary data regarding the skeletal effects of age-related changes in calcium and vitamin D metabolism in older men.
A prospective study to determine how low bone mineral density and/or vertebral compression fractures associate with pain in adults with sickle cell disease
To conduct a sham-controlled study to rigorously evaluate the effect of Spry Belt treatment on key bone turnover markers (BTMs) over a 12-week period. The investigators will calculate the percentage and absolute changes from baseline for several BTMs for both the active and sham treatment groups.
This is a phase 3, randomized, double-blind, placebo-controlled study to evaluate new or worsening lens opacifications in men with non-metastatic prostate cancer receiving denosumab for bone loss due to androgen deprivation therapy.
The investigators earlier have shown that treatment of patients with juvenile osteoporosis with alendronate (Fosamax) for 12 months increased the bone density without side effects. In an open label study (10 patients) and double blind, crossover study (11 patients alendronate and 11 patients placebo), the investigators have further observed that alendronate increased the bone density significantly where as placebo (calcium and vitamin D) increased only minimally. These trials were completed. Thus, a post study is designed to evaluate the current status of the bone density and fractures after the patients discontinued the alendronate treatment. No treatment is involved.
The purpose of this study is to determine if certain drugs commonly used to treat multiple sclerosis have an effect on bone health.
The purpose of this research study is to evaluate the safety and effectiveness of the Spry Belt. The Spry Belt is intended to deliver energy to the user's skeleton to reduce the progression of age-related decrease in bone quality in postmenopausal women. Half of the participants will receive the active treatment, while the other half will receive the sham/placebo treatment.
The purpose of this study is to identify the best way to prevent bone loss in the first years after menopause. The HOPS study will compare bone loss at 12 months in women: 1) who take calcium and vitamin D only; 2) who take calcium and vitamin D plus the medication "risedronate"; or 3) who take calcium and vitamin D plus participate in bone-loading exercises. Our central hypothesis is that improvements in bone health will be greater in women randomized to bone-loading exercises with calcium and vitamin D compared to women who take calcium and vitamin D only or women who take calcium and vitamin D plus risedronate.
Zoledronic acid is a medicine being studied in people with low bone mass. Side effects such as headache, fever, muscle aches, and pains, may occur following the infusion. This study will investigate the use of over-the-counter medicines to improve these symptoms.
Primary hyperparathyroidism (PHPT), a disease characterized by excess parathyroid hormone (PTH) and high blood calcium, is one of the most common endocrine disorders. PHPT is seen most often in postmenopausal women. Many patients with PHPT have low bone mineral density (BMD) when bone mass is measured by dual energy x-ray absorptiometry (DXA), primarily at the forearm. There is currently no effective medical therapy which increases bone density at the forearm in patients with PHPT. PTH both builds and breaks down bone, and the pathways by which PTH mediates these actions are beginning to be identified. Prior research suggests that RANKL, a molecule important in bone metabolism, responds to PTH, and that if the RANKL is inactivated, PTH is shifted towards building bone. The investigators will study the effect of Denosumab, a therapeutic agent that binds to and inactivates RANKL, in 28 postmenopausal women with PHPT. Our hypothesis is that Denosumab will increase bone mineral density in primary hyperparathyroidism. The study will last two years, and subjects will be randomly assigned to receive either placebo or Denosumab for the first year of the study. In the second year, all subjects will receive Denosumab. Denosumab (60 mg) or placebo will be given every 6 months by an injection just under the skin. Study procedures performed will include bone mineral density tests by DXA, high-resolution peripheral quantitative computed tomography (HR-pQCT) scans, and assessments of biochemical markers of calcium metabolism and bone turnover using both blood and urine samples of subjects with PHPT.
The ability of vitamin D to modulate the immune system and strengthen bones may mitigate the adverse medication consequences of HIV/AIDS, but little is known about either the health benefits of vitamin D supplements, or about the optimal dosing regimen for patients on highly active antiretroviral therapy (HAART). This trial is a comparison of two regimens for administering vitamin D and calcium to HIV-positive individuals taking antiviral medications. This study will help physicians make evidence-based decisions about the most effective way to use vitamin D in their patients and enable the design of large multi-center trials in the future.
