Conditions
Brief summary
This is an open-label, parallel-group, phase 1, single center study to assess the relative bioavailability of CSL312 administered subcutaneously via a prefilled syringe assembled to an autoinjector compared to a prefilled syringe assembled to a needle safety device in healthy, adult subjects.
