Summary

This trial will test if a yearly injection of romosozumab, followed by an infusion of zoledronic acid, can help treat and prevent bone loss in older women with osteoporosis who live in long-term care facilities.

Who is the study for?
This trial is for women aged 65 or older with osteoporosis, living in long-term care facilities. They must have a bone density score of -2.5 SD or lower, a history of fractures, or meet certain risk criteria. Excluded are non-walkers, those with recent severe heart issues, kidney problems preventing IV treatment, recent stroke or heart attack victims, current users of specific osteoporosis meds and very low vitamin D levels.
What is being tested?
The study tests if romosozumab injections followed by zoledronic acid infusion can improve bone health in elderly women with osteoporosis at LTC facilities. It compares the effects to placebo treatments alongside standard calcium and vitamin D supplements.
What are the potential side effects?
Romosozumab may cause muscle pain, joint pain, headache; serious side effects include possible increased risk of heart attack and stroke. Zoledronic acid might lead to flu-like symptoms, fever; rarely it can cause jawbone problems and unusual thigh bone fractures.
