Intravenous Infusion of Human Mesenchymal Stem Cells (HMM910 ) in Postmenopausal Women With Osteoporosis at High Risk of Fracture

The primary objective of this study is to evaluate the safety and tolerability of human umbilical cord-derived mesenchymal stem cells for injection (HMM910 ) in postmenopausal women with osteoporosis who are at high risk of fracture.

Bone Health in Postmenopausal Women: The Effect of Exercise With or Without Medication for Osteoporosis

Osteoporosis is a systemic bone disorder characterised by a reduced bone mass and structural deterioration, increasing the risk of fragility fractures, particularly in women post-menopause. Bone mass and structure can be assessed by scans. Antiresorptive medications are commonly prescribed to reduce bone resorption, preventing further bone loss and thus reducing the possibility of fracture. Exercise can also benefit bone mass and structure but current evidence do not show whether exercise is more, or less, effective in combination with antiresorptive medication. This study will compare the effect of a brief, home-based exercise programme on bone mineral and structural properties in women taking/ not taking antiresorptive medication.

A Clinical Study on the Effect of Discontinuing Alendronate in Postmenopausal Women With Osteoporosis After a Treatment Period Without Fractures

The goal of this clinical trial is to study the effects of discontinuation of Alendronate treatment for three years. The participants are postmenopausal women with osteoporosis, who have had a treatment period without fractures. The study will answer: * What is the rate of fragility fractures during the study? The hypothesis is that discontinuation of Alendronate after a fracture-free period does not raise the 3-year fracture risk. * Are there predictors of significant bone loss after discontinuation of Alendronate? The hypothesis is that clinical, biochemical, cellular, or molecular characteristics can predict bone loss. Researchers will compare the outcomes of discontinuation of Alendronate with continuing treatment. Participants will be randomly assigned to a group. Participants will: * Either take alendronate once weekly for three years OR discontinue their treatment * Visit the clinic at 6 and 18 months for blood samples * Visit the clinic at the start of the study and after 1, 2, and 3 years for bone scans and blood samples.

Efficacy of Romosozumab and Denosumab Combined Treatment in Postmenopausal Osteoporosis Patients with Multiple Fragility Fractures

The aim of this clinical trial is to investigate the effectiveness of romosozumab started without stopping denosumab in patients diagnosed with postmenopausal osteoporosis with a very high risk of fragility fractures and who is under at least 2 years of denosumab treatment. The main questions aimed to answer are: * Does it effective to prevent fractures add Romosozumab to ongoing denosumab treatment? * If it is appropiate to quit denosumab for starting 1 year romosozumab treatment? * If there is complications in denosumab and romosozumab combination treatment? Researchers will compare the Romosozumab 210mg subcutaneous(sc) monthly plus denosumab 60mg per 6 months sc treatment to prooceeding denosumab treatment and romosozumab 210mg monthly treatment in patient whom denosumab cessaced. Participians are postmenopousal women with osteoporosis and they are under at least 2 years of treatment with denosumab and they will: * Add 210 mg monthly romosozumab sc injection or switch to 210 mg monthly romosozumab sc injection or proceed 60mg per 6 months denosumab sc injection * Visit the clinic at least once every 3 months and first month of new treatment regimen, blood tests per 3 months and Bone mineral density examination per 6 months * Keep a diary of their symptoms

Development of a Wearable Device for Osteoporosis Prevention and Fracture Risk Reduction in Women

This project aims to determine the impact on bone health of: A lifestyle intervention promoting impact-based activities and physical activity for nine months. The same program enhanced with home-based strength training. A control group without supervision, continuing with standard care. The study will evaluate the persistence of changes after these interventions during a 12-week follow-up. By employing diverse strategies, the project seeks to identify barriers and facilitators to using technology for promoting healthy lifestyles in this demographic. Additionally, it will, for the first time in Spain, establish predictive models to assess the efficacy of non-pharmacological interventions in osteoporosis prevention, in collaboration with the public health system. These models will also predict adherence to technology-based behavioral interventions. ELIGIBILITY CRITERIA Eligible Participants: Postmenopausal women aged \>40 years, within 8 years post-menopause. Sedentary lifestyle. Willingness to provide informed consent. Exclusion Criteria: Surgically induced menopause or cancer treatment. Low BMI (\<18 kg/m²). Excessive alcohol consumption (≥3 drinks/day). Smoking. Unstable cardiovascular disease, rheumatoid arthritis, chronic kidney disease. Diagnosed conditions altering bone metabolism (e.g., hyperthyroidism). Recent fractures or mobility limitations. Recent engagement in structured physical activity programs. Recent use of glucocorticoids or hormone replacement therapy. VARIABLES TO BE MONITORED Body Composition: Lean mass, fat mass, bone mass, and waist circumference. Bone Health: Bone density of lumbar vertebrae and femur via densitometry and microarchitecture evaluation using quantitative CT. Biomarkers: Assessment of bone resorption and remodeling markers. Physical Function: Functional assessments (e.g., gait speed, jumping ability, lower limb strength). Physical Activity: Objectively monitored with accelerometers, analyzing sedentary, light, and moderate-to-vigorous activities. Nutritional Intake: Monitored using dietary recall tools. Quality of Life: Assessed using the Menopause Rating Scale (MRS). TRAINING PROTOCOL A. Impact-Based Physical Activity Program: Participants will utilize a validated biosensor (Muvone®) to track steps and impacts, targeting 50 multidirectional jumps and 10,000 steps per day, emphasizing brisk walking. B. Home-Based Strength Training Program: Two weekly sessions, progressing from 20 to 42 minutes, targeting major muscle groups (e.g., squats, hip extensions). Sessions include warm-ups, multi-joint exercises, and recovery periods. C. Control Group: Participants receive general advice on physical activity and nutrition without supervised programs or app access. FOLLOW-UP After 36 weeks, participants will resume daily routines without app feedback. At the 12-week follow-up, they will return for questionnaires and physical assessments. This structured approach ensures rigorous evaluation and facilitates integration of findings into public health strategies.
