Trial Summary

What is the purpose of this trial?

Investigators will test the hypothesis that an increase in bone turnover markers (e.g. carboxy-terminal collagen crosslinks (CTX) and P1NP) in patients currently taking chronic glucocorticoids will be attenuated more in those who switch from denosumab to "late" zoledronic acid (9 months after last denosumab dose) compared to participants randomized to "early" zoledronic acid (6 months after last denosumab dose) or weekly alendronate (6 months after last denosumab dose).

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does require that you have been on glucocorticoids for at least 3 months and continue them for at least 6 more months. If you are taking bisphosphonates, you must not have used them in the past 2 years.

What data supports the effectiveness of the drug Denosumab for osteoporosis?

Denosumab has been shown to significantly increase bone mineral density and reduce the risk of fractures in postmenopausal women with osteoporosis. It is more effective at improving bone density than continuing treatment with bisphosphonates, and it decreases vertebral fractures by 68%, nonvertebral fractures by 19%, and hip fractures by 42% over at least 36 months.12345

Is Denosumab safe for humans?

Denosumab, used for treating osteoporosis, has been shown to be generally safe in humans, with common side effects including back pain, pain in the arms or legs, and high cholesterol. Long-term studies have not shown increasing trends in these side effects over time.13467

How is the drug Denosumab unique for treating osteoporosis?

Denosumab is unique because it is the first fully human monoclonal antibody that works by blocking a protein called RANK ligand, which prevents the formation and activity of cells that break down bone. It is administered as a subcutaneous injection every six months, offering a convenient dosing schedule compared to other treatments like bisphosphonates, which are often taken more frequently.138910

Eligibility Criteria

This trial is for men and women aged 18 or older who have been using glucocorticoids at a certain dose for over 3 months and will continue for at least another six. They must have osteoporosis as shown by bone density scores, or a history of fractures with less severe bone loss. Exclusions include various other bone diseases, recent cancer, dental issues, malnutrition disorders, pregnancy/breastfeeding without contraception use, and intolerance to study drugs.

Inclusion Criteria

I have been taking a steroid medication equivalent to more than 7.5 mg of prednisone daily for over 3 months and will continue for at least 6 months.
My bone density is low, or I've had a fracture due to weak bones.

Exclusion Criteria

I have been diagnosed with Addison's disease.
Not a good candidate for study participation in opinion of investigator
I cannot take denosumab due to bad reactions or allergies.

Treatment Details

Interventions

  • Denosumab
Trial Overview The study tests if switching from Denosumab (DMAB) to 'late' zoledronic acid (9 months after last DMAB dose) versus 'early' zoledronic acid (6 months after last DMAB dose) or weekly alendronate affects bone turnover markers in patients on long-term steroids differently.

Findings from Research

Denosumab, a monoclonal antibody that inhibits osteoclast activity, has been shown to significantly increase bone mineral density for over 3 years and reduce the risk of fractures, including a 42% decrease in hip fractures.
The safety profile of denosumab is comparable to other osteoporosis treatments, although there are concerns about potential risks such as immunosuppression and cancer.
The clinical use of denosumab for the management of low bone mineral density in postmenopausal women.Harris, KB., Nealy, KL., Jackson, DJ., et al.[2015]
Denosumab, a monoclonal antibody that targets RANKL, significantly reduces the risk of fractures in postmenopausal women with osteoporosis, showing a 68% reduction in new vertebral fractures and a 40% reduction in hip fractures over a 3-year trial.
Long-term treatment with denosumab did not show increasing trends in adverse events, indicating that its safety profile remains stable over 6 years, even when comparing data from initial placebo recipients who later received the treatment.
Safety Observations With 3 Years of Denosumab Exposure: Comparison Between Subjects Who Received Denosumab During the Randomized FREEDOM Trial and Subjects Who Crossed Over to Denosumab During the FREEDOM Extension.Watts, NB., Brown, JP., Papapoulos, S., et al.[2018]
Denosumab (XGEVA®) is a monoclonal antibody that effectively inhibits bone resorption by preventing the activation of osteoclasts, making it a targeted treatment for patients with bone metastases.
In Phase 3 clinical studies, denosumab was found to be superior to zoledronic acid in delaying skeletal-related events (SREs) by a median of 8.2 months, suggesting it may be a more effective treatment option for these patients.
