Brief Summary

This is a phase 1, single-center, first-in-human study to assess the safety, pharmacokinetics and pharmacodynamics of DS-2741a after subcutaneous injection in healthy Japanese male volunteers and Japanese participants with moderate to severe atopic dermatitis.

Detailed Description

This study consists of three parts. Part 1 and Part 3 are a single ascending and multiple dose study to assess the safety, pharmacokinetics and pharmacodynamics of DS-2741a after subcutaneous injection in healthy Japanese male participants.
