Active clinical trials for "Osteoporosis, Postmenopausal"

Osteoporosis is characterized by decreased bone strength and it is prevalent among postmenopausal women but also occurs in men and women with underlying conditions or major risk factors associated with bone demineralization. Its chief clinical manifestations are vertebral and hip fractures, although fractures can occur at any skeletal site.The World Health Organization (WHO) operationally defines osteoporosis as a bone density that falls 2.5 standard deviations (SD) below the mean for young healthy adults of the same gender-also referred to as T-score of -2.5. Postmenopausal women who fall at the lower end of the young normal range (a T-score of >1 SD below the mean) are defined as having low bone density (osteopenia) and are also at increased risk of osteoporosis. More than 50% of the fractures, including hip fractures, among postmenopausal women occur in this group. Teriparatide is one of the most effective treatment options for osteoporosis. But the cost of teriparatide is prohibitively expensive and in countries like India with limited personal resources of the individuals, its not a feasible option in the majority of the patients with severe osteoporosis. The investigators aim to compare weekly versus daily teriparatide therapy in an open label non inferiority trial and if successful, the investigators anticipate, the cost of treatment could be reduced considerably so that treatment becomes more affordable to a larger number of patients. Also with weekly therapy, number of multiple injections could be brought down.

This study will assess the pharmacokinetics and safety and explore therapeutic effects with once-weekly recombinant human parathyroid hormone for injection ( 1-34 ) ( G56W1 ) in women with post-menopausal osteoporosis .The anticipated time on study treatment is 24 weeks, and the target sample size is 148 individuals.

Osteoporosis is a common senile disease with a high incidence. The Chinese medicine differentiation treatment has small side effects and can be taken for a long time, which has certain advantages. This project adopts the experience of the person in charge of the project-Xulin Jiangu Granules and clinically collects patients with postmenopausal osteoporosis (kidney deficiency and blood stasis syndrome).

This randomized open label clinical trial will evaluate the effect of continued denosumab alone over 18 months versus denosumab with added abaloparatide for 18 months. 70 postmenopausal women will be enrolled over a period of 18 months. The co-primary outcomes will be group differences in bone mineral density (BMD) of the total hip and lumbar spine at 18 months. Secondary outcomes will include group differences in bone mineral density (BMD) at the femoral neck, trochanter and wrist sites at 6, 12 and 18 months, spine and total hip bone mineral density (BMD) at 6 and 12 months and trabecular bone score (TBS) at 18 months. Secondary outcomes will also include within group changes from baseline for each of these variables. Bone turnover markers will also be measured to demonstrate that PINP levels will increase with administration of abaloparatide even in the setting of ongoing denosumab, while CTX levels will remain low.

A multicenter, randomized, double-blind, placebo-controlled phase III clinical study will be conducted to evaluate the efficacy and safety of LY06006 in the treatment of postmenopausal women with osteoporosis at high risk for fracture, as well as an exploratory population pharmacokinetic analysis of LY06006.

Acute phase response (APR) is one of the most common adverse events in osteoporosis with zoledronic acid treatment. It's reported that this reaction is related to the blockade of the mevalonate pathway, leading to isopentenyl pyrophosphate (IPP) accumulation. And the latter can active γδT cells in the circulation, resulting in inflammatory cytokine release. Statins can inhibit the conversion of HMG-CoA to mevalonate that may reduce the accumulation of IPP. Therefore, it is possible that statins can be taken in advance to reduce APR caused by zoledronic acid infusion.

HYPOTHESIS: - A multicomponent exercise program where strength exercises are performed with blood flow restriction obtains better values in densitometry and bone mass of osteoporotic patients with respect to the same multicomponent exercise program where strength is worked without flow restriction. INTERVENTION: The recruitment of the population will be carried out between July and November 2021, with the collaboration of the Consorci Sanitari de Terrassa (CST), which brings together a hospital center and different primary care centers (CAP). The primary care physicians and rheumatologists of the CST will receive an e-mail from the hospital management, informing them of the study to be carried out so that, if they consider it appropriate, they can inform their patients. Intervention of the intervention and control group: Each volunteer will be assigned to an intervention group either to the control group (CG) or experimental group (EG). The control group and intervention group will receive the same multicomponent exercise program, based on specific literature for being an effective, safe and feasible training for both elderly people {{2091 Bouaziz, Walid 2016;}} {{2092 Fragala,M. S. 2019;}}, with or without frailty {{2093 Cadore, Eduardo L 2014;}} {{2094 Casas-Herrero, Alvaro 2019;}} {{2088 Fernández-García, Ángel Iván 2020;}} and/or with osteoporosis {{2089 Moradell, Ana 2020;}}. The main difference between both groups is that the experimental group (EG) will perform the strength exercises with flow restriction (BFR) while the control group (CG) will not have any restriction. The periodicity of both groups will be 2 sessions per week, with a duration of 65 minutes per session and the duration of the intervention of 6 months and a follow-up 12 months after the beginning of the intervention (see scheme). The training will be supervised at all times by a physiotherapist with more than 10 years of experience in multicomponent exercise. The sessions will include both limb and trunk work and will have a clear functional objective, focusing on activities of daily living (ADL). Each session will work on all the basic physical abilities (strength, balance, endurance, flexibility and coordination) and will be divided into: 10 minutes of initial warm-up. This is divided into 8 minutes walking on a treadmill or cyclohergometer with an intensity corresponding to 30% of heart rate reserve. Followed by 2 minutes of active mobilizations in both upper and lower extremities. 20 minutes of strength exercises. These will be interspersed with the rest of the exercises and will include the different extremities and trunk. During the first month, training will be carried out with loads corresponding to 20% of 1 repetition maximum (RM) and from the second month onwards it will be increased to 30-35% of 1 RM. 10 minutes of resistance exercises. These exercises will be interspersed with the rest to make the session much more enjoyable. 10 minutes of coordination and balance exercises. These exercises will be interspersed with the rest of the activities. 5 minutes of flexibility. These exercises will be performed interspersed with the strength and endurance exercises. 5 minutes of return to calm and relaxation. To facilitate the monitoring of the researcher who will apply the intervention, each group will be subdivided into smaller groups (ratio of 5 subjects per researcher).

The primary objective of this study is to compare efficacy and safety of two formulations of teriparatide 20 mcg/day plus calcium and vitamin D in postmenopausal women with osteoporosis.

This proposed study was designed to investigate the prevalence of a 5-year incident osteoporotic fracture and evaluate the association of a 5-year change of 25-hydroxyvitamin D (25[OH]D)/bone turnover makers/bone mineral density (BMD) with the incident fracture in the Chinese postmenopausal women, based on an endeavor of a 5-year post-baseline follow-up visit of a previous cross-sectional study, PK-VF, in which 1724 participants were enrolled and examined.

For nearly 112 million patients with osteoporosis in China, it is of great significance for preventing and treating by clearly understanding the molecular mechanism of kidney deficiency. Thus, the research group has demonstrated in the earlier research that CLCF1 is an associated gene that can regulate JAK2/STAT3 signal pathway and impact bone metabolism for kidney yin deficiency of postmenopausal osteoporosis (PMOP). To make clear understanding of the direct-acting mechanism of CLCF1 for bone metabolism, this study intends to: ①observe impacts of low expression of CLCF1 upon immunities in mice and OPG/RANKL/RANK signal system using the technology of adenovirus associated virus. ②explore impacts of over-expression and silencing of CLCF1 on B lymphocytes by culcuturing the cells together with osteoblasts. ③ analyze the impacts of treating kidney yin deficiency of PMOP by Liuwei Dihuang pill upon immunities and OPG/RANKL/RANK system, and discuss the mechanism of regulating bone metabolism by CLCF1 by OPG/RANKL/RANK system via the bridge between immune system and bone metabolism, so as to demonstrate if the hypothesis of this study that "the molecular osteoimmunological mechanism of kidney yin deficiency of postmenopausal osteoporosis (PMOP) is possibly closely related to the impacts of CLCF1 regulation of OPG/RANKL/RANK signal system on bone metabolism" is right or not.
