Active clinical trials for "Osteoporosis, Postmenopausal"

The study will evaluate the efficacy and safety of transitioning postmenopausal women on current alendronate therapy to denosumab. Endpoints studied will include bone mineral density, bone turnover markers and bone histology in a subset of subjects.

To confirm the non-inferiority of 75 mg risedronate tablets taken on 2 consecutive days per month as compared to 5 mg risedronate tablets taken daily in increasing bone mass in lumbar spine in postmenopausal women with osteoporosis. To confirm the efficacy of 75 mg risedronate tablets taken on 2 consecutive days per month in postmenopausal women with osteoporosis in increasing bone mass in proximal femur, femoral neck and femoral trochanter and decreasing bone resorption. To confirm general safety of 75 mg risedronate tablets taken on 2 consecutive days per month as compared to 5 mg risedronate taken daily.

The purpose of this study is to assess the dose-response on the percent change from baseline in lumbar spine bone mineral density (BMD) at lumbar vertebrae 1 to 4 (L1- L4) when odanacatib (MK-0822) 10 mg, 25 mg, 50 mg or placebo is orally administered once weekly for 52 weeks to Japanese involutional osteoporosis participants. The study will also assess safety and tolerability of odanacatib (10, 25, and 50 mg) in these participants. The study will enroll approximately 280 participants and randomly assign them to 3 different doses of odanacatib or placebo for 52 weeks, along with supplemental vitamin D3 and calcium carbonate. The primary efficacy hypothesis is that a dose-response relationship on the percent change from baseline in lumbar spine BMD (L1- L4) is seen when odanacatib 10, 25, 50 mg or placebo is orally administered once weekly for 52 weeks to involutional osteoporosis participants. The primary safety hypothesis is that odanacatib will be safe and well tolerated over 52 weeks to involutional osteoporosis participants.

The purpose of this study and 12 month extension is to evaluate the effects of two investigational drugs on osteoporosis in postmenopausal women.

This study will assess the efficacy and safety of intravenous administration of Bonviva regimens in women with post-menopausal osteoporosis, compared to oral daily administration. Patients will also receive daily supplementation with vitamin D and calcium. The anticipated time of study treatment is 2+ years, and the target sample size is 500+ individuals.

The purpose of this study is to compare treatment with both teriparatide and raloxifene with teriparatide alone. The study will evaluate any side effects that may be associated with the two drugs and may help to determine whether teriparatide and raloxifene together can help patients with osteoporosis more than teriparatide alone.

The purpose of this trial is to study the efficacy of a single-dose monthly dosing regimen as compared to the standard daily dosing regimen of risedronate 5 mg daily.

To determine the effect and safety of menatetrenone on treatment of postmenopausal osteoporosis comparing with alfacalcidol.

The purpose of this study is to evaluate the effect of alfacalcidol 1 µg daily on the number of fallers in postmenopausal, alendronate-treated, osteopenic or osteoporotic women. primary outcome = number of fallers (patients with at least one locomotor fall incl.mixed falls)

Osteoporosis is defined as a systemic disease of bone mineralization, characterized by a decrease in bone mineral density that causes bone fragility and increases the risk of fractures during menopause. Recently, a high prevalence of hypovitaminosis D has been found worldwide, which could trigger a state of secondary hyperparathyroidism that can worsen the state of postmenopausal patients with osteoporosis. An open-label, clinical trial was conducted in Mexican women with postmenopausal osteopenia-osteoporosis to determine the efficacy of the combined treatment with risedronate and high-dose vitamin D in improving bone mineral density, hyperparathyroidism, and hypovitaminosis D.
