Filter by:This study analysed and reported on the study data from three similar, risedronate studies, 1996052, 2003073, and 2003096. The objective of the study was to determine the differences in the iliac crest bone histomorphometry and bone quality in postmenopausal women who had received long term therapy with risedronate.
Individuals with spinal cord injury sustain significant loss of bone mass in their lower extremities (20-40% or more). This study evaluates the ability of PTH and weight-bearing, two interventions that build bone, to increase bone mass in this population.
The goal of this clinical research study is to see if ibandronate can help to slow the rate of bone loss that may occur in patients who have received a bone marrow transplant for blood cancer. This study plans to address the following hypotheses: 1. The addition of Ibandronate initiated immediately after the transplantation will prevent bone loss in patients undergoing allogenic bone marrow transplantation (BMT) with underlying hematologic malignancies or hematologic disorders. 2. BMT patients who require prolonged steroid and other immunosuppressive treatment for Graft versus Host Diseases(GVHD) have a higher rate of bone loss, which can be prevented or attenuated by Ibandronate. Specific objectives to test these hypotheses are: 1. Primary Objective: 1. To prospectively compare the bone mineral density changes of lumbar spine, femoral neck and total hip between patients randomly assigned to ibandronate and control group over 12 months post bone marrow transplantation at the University of Texas MD Anderson Cancer Center. 2. Secondary Objectives: 1. To measure and compare the accumulated level of steroid used in both treatment and control groups. 2. To collect and compare the level of serum C-terminal telopeptide (CTX) in both treatment and control groups to monitor the bone turnover rate for the duration of the study. 3. To conduct a cost-effectiveness analysis of participating patients for both outcomes on bone mineral density (measured data) and skeletal-related events (modeled data). 4. To record incidence of bone fractures and the graft rate in both treatment and control groups.
Hip fractures mostly occur in elderly people with low bone strength. Bone strength is determined by bone mineral density (BMD), bone turnover, microarchitectural and geometrical properties of the bone. Dual energy x-ray absorptiometry (DXA) is the standard technique to measure BMD. However, BMD just provides information regarding the quantity of mineral in bone, which is only one component of bone strength. To date there is no reliable method to assess bone strength in vivo. Therefore, a method to assess bone strength beyond BMD would provide additional information regarding the patients' risk of bone related fixation failure after fracture fixation. DensiProbe is a new diagnostic device that was developed for intra-operative assessment of mechanical stability of the bone in the proximal femur. It consists of a drill bit like tool and an electronic system to measure the peak torque to break-away of trabecular bone in the femoral head of patients undergoing DHS surgical treatment. In a cadaver study comparing bone mineral density measured by quantitative computed tomography with bone strength measured by DensiProbe a high correlation between these two parameters could be shown. In a clinical pilot study a significant correlation between DensiProbe measurements and BMD measured by DXA at the femoral neck in patients with hip fractures could be shown. However, no perfect correlation was expected because DensiProbe measures bone strength, which is only partly caused by BMD. Bone related fixation failure, such as secondary loss of reduction, is influenced by bone strength, bone mineral density, fracture type, fracture reduction and primary positioning of the implant. The predictive value of DensiProbe measurements for secondary loss of reduction needs to be investigated. If DensiProbe turned out to be an effective screening tool for patients with low bone strength that are on higher risk of the aforementioned complications these patients may in future benefit from alternative treatment methods (e.g. augmentation techniques) in order to reduce bone related fixation failure. The primary aim of the present study is to investigate if bone strength measured by DensiProbeTM Hip (DensiProbe) is an independent factor to predict secondary loss of reduction (screw migration of 5 mm or more and / or telescoping of 10 mm or more) in patients with hip fractures after fracture fixation with DHS.
It is a double blind randomized study aiming at estimating the efficiency of oral bisphosphonates on the decrease of osteoporosis by comparing the evolution of densitometric values between two groups of children (treatment versus placebo).
The purpose of this study is to estimate Osteoporosis' prevalence in France and is a pilot study in the Department of the Alpes-Maritimes.
Patients with prostate cancer treated in outpatient clinics will be recruited by their urologist physician. Primary Objective: To evaluate the compliance in male patients with prostate cancer treated with Bisphosphonate and that suffered from Osteopenia/osteoporosis. Secondary objectives: To evaluate the compliance of family physicians to prescribe Bisphosphonate for patients upon recommendation by Urologists. To evaluate the overall number of patients treated by Bisphosphonate in the out-patient clinics, To evaluate incidence of osteopenia/osteoporosis in this study population.
The purpose of this research study is to evaluate the safety and effectiveness of this investigational drug for the treatment of menopausal symptoms while protecting the endometrium (uterine lining) and preventing postmenopausal osteoporosis. Subject participation will last approximately 14.5 months.
The purpose of this study is to determine the maximum tolerated concentration (MTC) of bisphosphonate with a fixed dose of rHuPH20 administered SC, the MTC of bisphosphonate without rHuPH20 administered SC, the optimal dose of rHuPH20 to deliver bisphosphonate SC at MTC, and to compare the PK of SC administered bisphosphonate at MTC with optimal dose rHuPH20 to bisphosphonate alone.
This study will evaluate the bioequivalence of alendronate in combination with vitamin D (cholecalciferol) compared to alendronate alone and the bioequivalence of vitamin D in combination with alendronate compared to vitamin D alone.
