Description

Summary

The primary objective of this study is to assess the efficacy of ALXN2220 in the treatment of adult participants with ATTR-CM by evaluating the difference between the ALXN2220 and placebo groups as assessed by the composite endpoint of all-cause mortality (ACM) and total cardiovascular (CV) clinical events.
