ClinicaliQ Trial Snapshot
  • Study to Check the Safety of Fazirsiran and Learn if Fazirsiran Can Help People With Liver Disease and Scarring (Fibrosis) Due to an Abnormal Version of Alpha-1 Antitrypsin Protein — Recruiting • Phase III • Gastroenterology • NCT05677971.
  • Treatment being tested: Fazirsiran, an investigational therapy designed to reduce liver fibrosis in patients with alpha-1 antitrypsin (AAT) deficiency-related liver disease, compared against placebo.
  • Patient eligibility overview: Adults with genetically confirmed AAT deficiency presenting with established liver fibrosis/cirrhosis, likely requiring documented evidence of disease progression and preserved baseline liver function sufficient for safe study participation.

What This Trial Is Studying

The main aim of this study is to learn if fazirsiran reduces liver scarring (fibrosis) compared to placebo. Other aims are to learn if fazirsiran slows down the disease worsening in the liver, to get information on how fazirsiran affects the body (called pharmacodynamics), to learn if fazirsiran reduces other liver injury (inflammation) and the abnormal Z-AAT protein in the liver, to get information on how the body processes fazirsiran (called pharmacokinetics), to test how well fazirsiran works compared with a placebo in improving measures of liver scarring including imaging…

Eligibility Snapshot
  • : * The participant must have a diagnosis of the Z allele homozygotes (PiZZ) genotype AATD. PiZZ diagnosis from source verifiable medical records is permitted. Otherwise, participants must undergo PiZZ confirmatory testing (genotyping for PiS and PiZ alleles) at screening. PiMZ or PiSZ genotypes are not permitted. * The participant, of any sex, is aged 18 to 75 years, inclusive. * The participant's liver biopsy core sample collected should meet the requirements of the protocol. * The participant has evidence of METAVIR stage F2, F3, or F4 liver fibrosis, evaluated by a centrally read baseline liver biopsy during the screening period; or confirmed as meeting all the entry criteria by central reading of a previous biopsy conducted within 6 months before the estimated enrollment date using an adequate liver biopsy and slides as defined in the study laboratory manual. * The participant has a pulmonary status meeting the protocol's requirements. * It must be confirmed that the participant does not have HCC. Participants will be screened for HCC with alpha-fetoprotein (AFP) and abdominal ultrasound. If the participant has any of the following, they will be required to have contrast-enhanced CT or MRI imaging to exclude HCC before randomization. *…
