This study will assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of single ascending doses (SADs) of ALXN1920 subcutaneous (SC) and of a single dose of ALXN1920 intravenous (IV) in healthy adult participants.


Clinical Trial Description

This is a first-in-human study in healthy adult participants. Eligible participants will be randomly assigned in a 3:1 (ALXN1920:Placebo) ratio in each of the treatment cohorts.
