Comparing two treatment regimens for osteoporosis in postmenopausal women

Effects of Cycle Therapy With Romosozumab and Denosumab 2 Years vs 1 Year Romosozumab Followed by 1 Year Denosumab in Postmenopausal Osteoporosis Patients-A Randomized Control Trial

PHASE4 · National Taiwan University Hospital · NCT06938152

This study is testing two different treatment plans for osteoporosis in postmenopausal women to see which one helps improve bone strength and reduce the risk of fractures better.

What this trial studies

This clinical trial evaluates the effectiveness of a 24-month cyclic therapy regimen using Romosozumab followed by Denosumab against a traditional sequential treatment regimen of 12 months each of Romosozumab and Denosumab. The study aims to optimize treatment strategies for postmenopausal women suffering from osteoporosis by assessing improvements in bone mineral density and fracture risk. Participants will be randomly assigned to one of the two treatment groups and monitored over the course of the study to determine which regimen yields better therapeutic outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are postmenopausal women aged 50-90 years with a bone mineral density T-score of less than -3.0.

Not a fit: Patients with a history of certain medical conditions, recent osteoporosis treatments, or allergies to the study medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies that enhance bone health and reduce fracture risk in postmenopausal women with osteoporosis.

How similar studies have performed: While there have been studies on the individual effects of Romosozumab and Denosumab, this specific cyclic therapy approach is novel and has not been extensively tested.
