Bisphosphonate Therapy for Osteogenesis Imperfecta

18 participantsStarted 1999-08

Plain-language summary

The study is designed to evaluate the efficacy and safety of "Bisphosphonate Therapy for Osteogenesis Imperfecta (OI)." We, the researchers at Indiana University School of Medicine, are characterizing the changes effected by oral bisphosphonate therapy and comparing them to a regimen of intravenous bisphosphonate therapy in a group of children with OI and also in children with other disorders that result in low bone mass and fractures.
