Active clinical trials for "Osteoporosis"

Background The standard care in patients with a painful osteoporotic vertebral compression fracture (VCF) is conservative therapy. Percutaneous vertebroplasty (PV), a minimally invasive technique, is a relatively new treatment option. Recent randomized controlled trials (RCT) provide conflicting results: two sham-controlled studies showed no benefit of PV while an unmasked but controlled RCT (VERTOS II) found effective pain relief at acceptable costs in patients with acute VCFs. A still ongoing masked RCT (VERTOS IV) focuses on acute VCFs defined as ≤ 6 weeks. VERTOS III focused on conservative treatment and found that half of patients still had disabling pain after 3 months or longer. These patients with sustained pain after 3 months may benefit from PV. Objective To compare pain relief after PV with a sham intervention in selected patients with a chronic osteoporotic VCF ( three months or longer) using the same strict inclusion criteria as in VERTOS II an IV. Secondary outcome measures are back pain related disability and quality of life. Methods The VERTOS V study is a prospective RCT with pain relief as primary endpoint. Inclusion criteria are a VCF of thoracic level 5 or lower with focal tenderness at fracture level, assessed by an internist on physical examination and a Visual Analogue Scale (VAS) score ≥ 5 for three months or longer, decreased bone density defined as T score ≤ -1 and age 50 years or older. 94 patients will be included, 47 in each arm. Crossovers are not allowed. Follow-up is at regular intervals during one year period with VAS score for pain as primary endpoint. Secondary endpoints are back pain related disability and quality of life measured with the Quality of Life Questionnaire of the European Foundation for Osteoporosis and physical function measured with the Roland Morris Disability questionnaire. Conclusion Vertos V is a methodologically sound masked randomised sham controlled trial of vertebroplasty in patients with sustained pain 3 months or longer after a vertebral compression fracture.

The purpose of this study is to investigate how teriparatide or zoledronic acid affects the bone of postmenopausal osteoporotic women after 6 months of treatment as determined by a bone biopsy sample taken from the iliac crest (upper part of the pelvis). After completing 12 months of treatment all participants are eligible to participate in an additional 12-month open label extension.

The primary objective was to determine the effect of treatment with romosozumab versus placebo at month 12 on the percent change from baseline in bone mineral density (BMD) at the lumbar spine in postmenopausal women with low bone density.

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

Tibolone 1.25 mg is an effective treatment for the prevention of osteoporosis and is expected to be effective in preventing fractures in osteoporotic women. Tibolone could be more acceptable for long-term use, in particular since it does not induce a regular withdrawal bleed. The objective of this trial is to compare placebo and tibolone, a steroid with tissue specific activity, in the prevention of spinal fractures in women meeting the WHO criteria for osteoporosis or who have asymptomatic vertebral fractures.

Vitamin D and calcium are essential in the treatment and prevention of osteoporosis. What dosage of vitamin D which is the ideal one, is not yet clear. We want to test the hypothesis that high dosage of vitamin D (i.e. 6500 IU/d) is better than standard dosage (800 IU/d) in a randomized double-blind trial. We will include 400 postmenopausal otherwise healthy women with T-score <= -2.0 in L2-4 or mean total hip. Everybody will receive calcium 1000 mg and vitamin D 800 IU every day. Half of the group will also receive vitamin D 40 000 IU/week, while the other half will have placebo. The study period is one year.

A research study to see how safe and effective MK0217 is when taken weekly for the prevention and treatment of steroid induced bone loss.

Male osteoporosis is a common and important clinical problem, associated with significant morbidity, mortality and societal expense. Approximately 10% of men =65 years of age are osteoporotic. The proposed study will evaluate efficacy and safety of oral ibandronate given 150 mg once-monthly for 12 months versus placebo in men with primary osteoporosis. Less frequent, once monthly, dosing is expected to improve patient's treatment adherence compared to a weekly dosing regimen.

This study was conducted among women who had previously received alendronate for 3 to 6 years during the Fracture Intervention Trial (FIT). Participants in the FLEX study were randomly assigned to receive alendronate (either 5 or 10 mg/day) or matching placebo during the next 5 years, in order to evaluate the effects of continuing or discontinuing alendronate treatment on bone mineral density and biochemical markers of bone turnover.

This 3 arm study will evaluate renal safety after administration of an intravenous (iv) injection or infusion of Bonviva, compared to oral alendronate, in patients with postmenopausal osteoporosis, at increased risk of renal disease. Patients will be randomized to receive Bonviva 3mg intravenous (iv) by a) injection or b) infusion once every 3 months, or alendronate 70mg per oral (po) weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
