The Effects of Potassium Citrate on Bone Metabolism
Bone DiseasesMetabolic2 moreSkeletal buffering of chronic acid loads may contribute to a significant amount of bone loss over time. Evidence from a few small short-term studies suggests that basic compounds, namely potassium citrate and potassium bicarbonate may reduce bone loss and improve bone density. The purpose of this study is to evaluate the effects of potassium citrate on bone metabolism. We hypothesize that administration of potassium citrate to postmenopausal women with osteopenia will reduce bone resorption and improve bone mineral density. Postmenopausal women with osteopenia (T score between -1.0 and -2.5) and no history of fracture will be randomized to either daily potassium citrate or placebo for one year. Primary outcomes will be markers of bone turnover, which will be measured over 12 months. Secondary outcomes will be bone mineral density, compliance, and adverse events.
A Study to Examine the Effects of an Experimental Drug on Women With Breast Cancer and Metastatic...
Breast CancerMetastatic Bone DiseaseThis is a 4-week study to examine the effects of a new experimental medication on women with breast cancer and established bone metastases. This study will enroll approximately 45 women. The primary hypotheses are: (1) odanacatib will result in a substantial suppression of urinary N-telopeptide of type I collagen (u-NTx) similar to that achieved with an intravenous (IV) infusion of zoledronic acid (ZA) over 4 weeks of treatment; and (2) odanacatib (MK-0822) will be safe and well tolerated during 4 weeks of treatment.
Study of Alendronate to Prevent and Treat Osteoporosis in Cystic Fibrosis Patients
Cystic FibrosisOsteoporosis2 moreThe primary objective of this study is to determine efficacy of 70 mg alendronate once weekly compared to placebo. This will be measured by percent changes in lumbar spine(LS) bone mineral density(BMD) in adult cystic fibrosis(CF)patients after one year of treatment. The investigators hypothesize that in adult CF patients with osteopenia or osteoporosis, alendronate 70 mg once weekly will produce a mean increase from baseline in lumbar spine BMD that is greater than that observed with placebo at 12 months.
Look AHEAD: Action for Health in Diabetes
DiabetesMyocardial Infarction4 moreThe Look AHEAD study is a multi-center, randomized clinical trial to examine the long-term effects of a lifestyle intervention designed to achieve and maintain weight loss. The study will investigate the effects of the intervention on heart attacks, stroke and cardiovascular-related death in individuals with type 2 diabetes who are also overweight or obese.
The Effect of Etelcalcetide on CKD-MBD
Chronic Kidney Disease Mineral and Bone DisorderRenal Osteodystrophy3 moreThe proposed study will investigate the effects of etelcalcetide on the bone and blood-vessel health in patients with CKD-MBD. The investigators will test if etelcalcetide makes bone and blood-vessels healthier. The study hypotheses are that are that etelcalcetide keeps bones strong and lowers the risk of calcium deposits in blood vessels. In Aim 1, the investigators will test if 9-months of treatment with etelcalcetide improves bone strength in twenty ESKD patients with hyperparathyroidism (HPT) by bone biopsy. In Aim 2, the investigators will test if 9-months of treatment with etelcalcetide decreases serum propensity to calcify blood vessels. The potential significance of this study is to provide first-time data on the ability of etelcalcetide to protect bone and blood-vessel health in patients with ESKD.
Custom Pack in Spine Surgery
Bone DiseasesSpine Cancer1 moreRecent evidence suggests the efficacy of "custom pack" procedure on the operators reduction time and on the contamination risk due to the opening of many sterile packs. Nevertheless ,the studies available are sponsored by the industry and their results are very few. The aim of this study is to evaluate the correlation and reliability of spine surgery "custom pack" efficacy in adult patients obtained in the reduction of surgery time, relative risks, and materials wasted compared with the standard surgical field procedure practice .
MRgFUS Versus EBRT in Patients With Metastatic Non-spinal Bone Disease
Secondary Bone CancerBone MetastasesThe objective of this trial is to collect and compare safety and effectiveness data of Magnetic Resonance guided Focused Ultrasound (MRgFUS) using the ExAblate 2100 device and radiotherapy in the treatment of metastatic bone tumors. This study is designed as a prospective, double arm, non-randomized study with External Beam radiation therapy (EBRT) serving as control arm. The study hypothesis is that MRgFUS is an effective non-invasive and safe treatment for the palliation of metastatic bone tumors with a low incidence of co-morbidity as compared to EBRT.
Radius Loading in Primary Hyperparathyroidism
Primary HyperparathyroidismBone Diseases5 moreThe purpose of the study is to determine the effect of forearm exercise on forearm bone density in post-menopausal women with or without primary hyperparathyroidism. The investigators hypothesize that forearm exercise will increase forearm bone density in patients with primary hyperparathyroidism more so than in patients without primary hyperparathyroidism.
Etelcalcetide to Treat Secondary Hyperparathyroidism in Hemodialysis Patients With Chronic Kidney...
Secondary HyperparathyroidismThe purpose of this study is to evaluate the effect of thrice weekly intravenous (IV) administration of etelcalcetide in the treatment of secondary hyperparathyroidism (SHPT) in hemodialysis patients with chronic kidney disease-mineral and bone disorder (CKD-MBD).
Bisphosphonate Therapy for Osteogenesis Imperfecta
Osteogenesis ImperfectaOsteoporosis1 moreThe study is designed to evaluate the efficacy and safety of "Bisphosphonate Therapy for Osteogenesis Imperfecta (OI)." We, the researchers at Indiana University School of Medicine, are characterizing the changes effected by oral bisphosphonate therapy and comparing them to a regimen of intravenous bisphosphonate therapy in a group of children with OI and also in children with other disorders that result in low bone mass and fractures.
