Study Summary

The main aim of this study is to learn if fazirsiran is safe during long-term use in people with liver disease caused by the abnormal Z-alpha-1 antitrypsin (Z-AAT) protein. People who have taken part in previous fazirsiran studies (AROAAT2001 \[NCT03945292\] or AROAAT2002 \[NCT03946449\]) can continue to receive fazirsiran every 3 months as long as they participate in this study, the study is ongoing or until health authorities in their country approve fazirsiran to be publicly available. The study may also provide information on whether fazirsiran has a long-term effect in reducing liver fibrosis or slowing down the progression of liver fibrosis in people with liver disease due to the abnormal Z-AAT protein.

Primary Outcome

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of the study intervention, whether or not it is considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study intervention. An SAE is defined as any untoward medical occurrence that results in death, is life-threatening, requires inpati
