Liver Fibrosis in Alpha-1 Antitrypsin Deficiency (Liver AATD)

Abdominal ultrasound will be done at the liver biopsy visits. The purpose of the ultrasound is to evaluate for the presence of liver fibrosis and identify the biopsy site.

Every study participant will be asked about their medical history and will have a physical exam done at the screening, year 1, year 2, and year 3 visits.

Every study participant will have and intravenous catheter (IV) placed at every study visit. The IV will be used for the collection of blood at the screening, year 2, year 2, and year 3 visits. It will also be used for the administration of medication at the first liver biopsy, as well as the year 3 visit if the biopsy is repeated.

At the screening, year 1, year 2, and year 3 visits, every participant will have blood collected from the IV that is placed in one of their veins.

At the screening and year 3 visits, every subject will complete a questionnaire which involves questions regarding liver health.

Every participating subject who passes the screening visit, will have a liver biopsy done with the use of lidocaine (a numbing medicine) injected into skin where the biopsy will be collected. At the time of the biopsy, either lorazepam (a medicine used to treat anxiety and cause relaxation) or midazolam (a medicine used to cause sleepiness and amnesia) and fentanyl (a medicine used to relieve pain) will be used. Once the relaxation medication and numbing medicine have been given, a sample of liver tissue will be collected using a needle biopsy device.

Every participating subject who passes the screening visit, will have a liver biopsy done with the use of lidocaine injected into skin where the biopsy will be collected. At the time of the biopsy, either lorazepam (a medicine used to treat anxiety and cause relaxation) or midazolam (a medicine used to cause sleepiness and amnesia) and fentanyl (a medicine used to relieve pain) will be used. After the biopsy is done, participants who continue to have pain may receive either oxycodone/acetaminophen or acetaminophen (medicines used to relieve pain). Any participant who experiences nausea may receive ondansetron (a medicine used to relieve nausea).
