Experimental Open-Label Fazisiran (also referred to as TAK-999 or ARO-AAT) |
After all enrolled participants completed the Week 16 visit, an interim analysis was performed to select a single dose level (25, 100 or 200 mg) for the open-label phase of the study. Fazirsiran 200 mg was the selected dose and all participants with fibrosis at Screening who completed the post-dose liver biopsy at Week 48 (or Week 72 or 96) receive this dose every 12 weeks for the duration of the study (open-label phase). |

Detailed Description
Participants will be enrolled to receive multiple subcutaneous injections of Fazirsiran Injection (also referred to as TAK-999 Injection or ARO-AAT Injection) or placebo. Eligible participants will require a pre-dose biopsy completed as part of the study within the screening window. However, any participant with a biopsy result within 1 year of screening showing no fibrosis does not require a pre-dose biopsy. Only participants who have liver fibrosis will undergo a post-dose biopsy and may continue treatment in an open-label phase.
