Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to assess the safety, tolerability, pharmacokinetics and immunogenicity of either single ascending intravenous (IV) doses of ABBV-243 or single ascending subcutaneous (SC) doses of ABBV-243 in healthy adult participants (Part 1), and a single intravenous (IV) dose in healthy Asian adult volunteers (Part 2

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
