ESTRELLA Trial Summary

This trial will test the safety and effectiveness of a new drug, belcesiran, in adults with a specific liver disease. The trial will have two groups of patients, who will receive different doses of the drug or a placebo. The trial will last 24 or 48 weeks, depending on the group, and patients will have a liver biopsy at the end to check for improvement.

Who is the study for?
This trial is for adults aged 18-75 with Alpha-1 Antitrypsin Deficiency-associated liver disease, confirmed by genotyping and liver biopsy. Participants must have normal lung, kidney, and liver function tests and agree to undergo two liver biopsies. Excluded are those with severe lung disease exacerbations in the past year, prior RNAi drug use, significant respiratory infections within three months before screening, or advanced liver disease (Child-Pugh Score B or C).Check my eligibility
What is being tested?
The study tests Belcesiran's safety and effects on patients with AATLD compared to a placebo. It's randomized (participants are put into groups by chance), double-blind (neither participants nor researchers know who gets what treatment), involving multiple doses across three cohorts differing in treatment duration, dose count, and timing of a second biopsy.See study design
What are the potential side effects?
While specific side effects for Belcesiran aren't listed here, common ones for similar treatments include injection site reactions, fatigue, abdominal pain or discomfort; potential risks may also involve changes in liver enzymes indicating possible organ stress.
