Denosumab for Fibrous Dysplasia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial is testing denosumab, a drug that helps strengthen bones, in adults with fibrous dysplasia, a condition where bones grow abnormally. Denosumab works by stopping the cells that break down bone tissue, aiming to reduce bone pain and improve bone strength.
Will I have to stop taking my current medications?
The trial requires that you have not used bisphosphonates (a type of medication for bone conditions) within one year before starting the study. Other current medications are not specifically mentioned, so it's best to discuss your medications with the study team.
Is Denosumab generally safe for use in humans?
Denosumab, also known as Prolia or Xgeva, is a biologic treatment that has been monitored for safety in various conditions, including rheumatoid arthritis. Safety data from registers in Europe and the UK show that biologic treatments can have adverse effects, such as infections and cardiovascular events, which are closely monitored to ensure patient safety.12345
How is the drug denosumab unique for treating fibrous dysplasia?
Denosumab is unique because it is a monoclonal antibody that targets RANKL, a protein involved in bone resorption, which is different from traditional treatments like bisphosphonates. It is administered as a subcutaneous injection, offering an alternative route and mechanism for managing bone-related conditions.678910
What data supports the effectiveness of the drug Denosumab for treating fibrous dysplasia?
Denosumab has shown promise in reducing pain and the size of bone lesions in patients with fibrous dysplasia, as seen in case reports where patients experienced improvements that were not achieved with previous treatments. Additionally, Denosumab is effective in other bone-related conditions, like osteoporosis, by targeting a protein involved in bone breakdown, which may explain its potential benefits in fibrous dysplasia.711121314
