About This Trial
The aim of this study is to compare the amount of efgartigimod in the blood over time after it is injected via Prefilled syringe (PFS) and Autoinjector (AI). The study will comprise 2 study periods of 3 weeks each. Each participant receives both efgartigimod PH20 SC AI and PFS treatments, in a different order. Participants will be in the study for up to approximately 9 weeks.
