Osteogenesis imperfecta (OI) comprises a heterogeneous group of genetic disorders characterized by increased bone fragility, low bone mass, and susceptibility to bone fractures with variable severity.
Biomarker and diagnostic research for osteogenesis imperfecta has been reported in the published literature.
No approved treatments are currently available for osteogenesis imperfecta. An additional 10 compounds hold orphan drug designation.
While no drugs are FDA-approved specifically for osteogenesis imperfecta, some of the following designated compounds may be used off-label in clinical practice. Treatment decisions should be made in consultation with a specialist familiar with this condition.
The following drugs have received orphan drug designation from the FDA for osteogenesis imperfecta. Orphan designation reflects regulatory interest and does not indicate approval for treatment.
