Brief Summary

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

This is a randomized, double-blind, double-dummy, placebo- and positive-controlled parallel study to evaluate the effect of ALXN2050 on the QT interval in healthy adult participants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants randomized to the treatment arm will receive ALXN2050 in a multiple-ascending doses fashion over 3 periods (treatment sequence ABC). Participants randomized to the control arms will be further randomized to 1 of 2 treatment sequences (treatment sequence DEF or GHI) to receive placebo or active control over 3 periods.
