Could a drug combo rebuild bones faster in osteoporosis?
NCT ID NCT07283887
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether combining two osteoporosis drugs (romosozumab and denosumab) works better than either drug alone for postmenopausal women with weak bones. About 90 women will receive one of three treatments for 6 months. The goal is to see which approach improves bone density most and to gather data for larger future studies.
