Treatment of Osteogenesis Imperfecta with Parathyroid hormone and Zoledronic acid
TOPaZ is a randomised open-label clinical trial for people with osteogenesis imperfecta (OI). The study aims to investigate whether a two-year spell of treatment with a drug called teriparatide (TPTD) followed by treatment with another drug called Zoledronic acid (ZA) reduces the risk of broken bones occurring in people with OI.
