Early intervention with anti-resorptives is essential in OI: a longterm murine study

Raggio Cathleen , Marino Josephine , Doty Steve , Pleshko Nancy , Boskey Adele

The oim/oim mouse resembles type III OI. Our study mimics clinical questions: is RANK-Fc as efficacious as ALN in reducing fracture number? Is RANK-Fc safe to administer to children? Is there any advantage to receiving RANK-Fc treatment post adolescence, following no treatment or ALN treatment from infancy through adolescence?All animal work was done under an IACUC-approval. Mice – n=200, WT or oim/oim. Treatment spanned a...

Switching from alendronate to RANKL blockade alters bone properties after 14 weeks of therapy in the oim/oim mouse

Objective: The purpose of this study was to determine whether osteogenesis imperfecta (OI) patients entering adulthood should continue with bisphosphonate therapy or would benefit from switching to a RANKL blockade therapy. To address this question, we used a mouse model of type III OI.Methods: Animal studies were performed under IACUC approval. OI (oim/oim) and wild-type (WT) mice were treated from 2–26 weeks with i) saline; ii) alendronat...
