Denosumab: Summary of the LUMC studies and The DeFiD trial – Dr. Natasha Appelman-Dijkstra at the 2023 FD/MAS Community Conference and ICFDMAS meeting

Dr. Natasha Appelman-Dijkstra discusses LUMC on Fibrous Dysplasia/McCune-Albright Syndrome (FD/MS), focusing on denosumab and burosumab. Differences between the care at LUMC and NIH are highlighted, emphasizing a mix of monostotic and polyostotic cases at LUMC.

Denosumab study: Positive effects observed, including decreased lesion size on sodium fluoride PET scans.

Burosumab study: Investigating hypophosphatemia treatment in FD patients. Safety endpoints include monitoring FD lesion activity and bone biopsies.

Patient testimonial: Positive effects of denosumab shared, emphasizing individualized treatment approaches.

Insurance coverage concerns: Addressing challenges related to expensive medications and advocating for high-normal phosphorus levels as a therapeutic goal.

Dr. Appelman-Dijkstra also emphasized the need to move beyond presenting case reports in the literature and focus on larger studies involving more patients.
