Summary

This study tests whether a second round of treatment with ALXN2220 is safe and can improve heart function in people with transthyretin amyloid cardiomyopathy, a condition where abnormal proteins build up in the heart. About 35 adults who previously received the drug will get it again and be monitored for 48 weeks. The goal is to see if the drug reduces protein buildup and helps the heart work better.
