Sanofi10 enrolled

Overview

This is a cross-over, Phase 1, 3-treatment period single sequence study. The purpose of this study is to characterize pharmacokinetics (PK), safety, and tolerability of single ascending oral doses of SAR441566 in healthy male Japanese participants, 18-55 years of age.

The duration of the study for a participant will be up to approximately 65 days.
