Active clinical trials for "Osteoporosis"

To evaluate the effect of estrogen treatment on adipocytic and osteoblastic parameters by histomorphometrically measuring adipocyte volume (AV/TV) and adipocyte numbers in goldner's stained iliac crest bone biopsy specimens collected from subjects recruited in the study (IRB number 21B85). The adipocytic parameters will be then correlated with osteoblastic parameters obtained previously during the course of the initai study involving the effect of transdermal estrogen on bone turnover in postmenopausal osteoporotic women.

To evaluate the efficacy of teriparatide based on measurements of bone mineral density at lumbar spine

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.

We have previously evaluated the safety and efficacy of Alendronate in 10 patients with juvenile osteoporosis during a 12-month clinical trial. We have documented that Alendronate improved BMD of the spine and hip without any major side effects. There were no additional fractures during therapy. The present study is designed to further evaluate the safety and efficacy of Alendronate in 20 children with juvenile osteoporosis using a double-blind, randomized, placebo-controlled, cross-over protocol.

The objective is to show superior efficacy of PTH (1-84) over risedronate in treating osteoporotic women for 12 months after having previously been treated with PTH (1-84) for 12 months followed by 12 months treatment with risedronate.

Efficacy: To investigate changes of structural bone properties in vivo using 3DpQCT ("Xtreme" CT, Scanco) in monthly oral ibandronate therapy for women with postmenopausal osteoporosis. Major structural bone parameters which determine bone strength and predict fracture risk earlier and more precisely are measurable in vivo by 3DpQCT. Safety: To assess the tolerability and safety of ibandronate therapy

The primary objective of this study is to compare risedronate 35 mg and placebo with respect to the percent change at 12 months for distal radius trabecular bone volume (BV/TV) in osteopenic postmenopausal women, as measured by three-dimensional peripheral quantitative computed tomography (3D pQCT). The secondary objectives are to compare the percent change from Screening/Baseline between the 2 treatment groups for the following measurements: Bone mineral density of the lumbar spine, femoral neck, femoral trochanter, and total proximal femur using a dual energy X-ray absorptiometry (DXA) scan at 12 and 24 months; 3D pQCT analysis of distal radius and distal tibia bone microarchitecture data at 6, 12, and 24 months; and Bone turnover markers (BTMs) of: fasting serum carboxyterminal cross linking telopeptide of type 1 bone collagen (CTX 1); serum aminoterminal propeptide of type 1 procollagen (PINP); and urine N-telopeptide cross-links (NTX) at 3, 6, 12, and 24 months.

The purpose of this study is to evaluate the effect of norgestimate/ethinyl estradiol on lumbar spine (L1-L4) and total hip bone mineral density (BMD) in pediatric subjects with anorexia nervosa.

This is a two part study (screening and treatment). The first part (screening) is designed to evaluate the percentage of patients missed in diagnosing osteoporosis by general practitioners (GP's). The second part (treatment) is designed to determine the preference by patients for the once monthly ibandronate or the once weekly alendronate.

This was a prospective, randomized, open-label, two arm phase III trial designed to evaluate the efficacy and safety of zoledronic acid in preventing bone loss in postmenopausal women with operable breast cancer who had received 4 to 6 years of adjuvant tamoxifen therapy after resection of the tumor. Patients were treated with letrozole 2.5 mg orally per day or letrozole 2.5 mg orally per day in combination with zoledronic acid 4 mg/6 months as an infusion. This trial did not recruit patients in the United States.
