Comparing Denosumab with Eldecalcitol or Vitamin D for Osteoporosis in Postmenopausal Women

Comparison of Efficacy of Denosumab With Eldecalcitol or Native Vitamin D in Postmenopausal Women With Osteoporosis.

Phase 4 Interventional Xi'an Honghui Hospital · NCT05884372

This study tests whether the medication denosumab works better than eldecalcitol or vitamin D in helping postmenopausal women with osteoporosis strengthen their bones.

What this trial studies

This clinical trial aims to evaluate the effectiveness of denosumab compared to eldecalcitol and native vitamin D in improving bone mineral density (BMD) in postmenopausal women diagnosed with osteoporosis. The primary focus is on measuring changes in BMD, while secondary objectives include assessing various health markers such as bone turnover, muscle strength, and quality of life. Participants will receive one of the three treatments and undergo regular assessments to monitor their progress. The study seeks to provide insights into the most effective treatment options for this demographic.

Who should consider this trial

Good fit: Ideal candidates for this study are postmenopausal women diagnosed with osteoporosis, as indicated by a BMD T value of ≤-2.5.

Not a fit: Patients with secondary osteoporosis due to conditions like hyperthyroidism or those who have previously received denosumab therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for postmenopausal women with osteoporosis, enhancing their bone health and overall quality of life.

How similar studies have performed: Previous studies have shown varying degrees of success with similar treatments for osteoporosis, but this specific comparison of denosumab with eldecalcitol and vitamin D is relatively novel.
