Alpha-1 Antitrypsin Deficiency clinical trials at University of California Health

9 in progress, 4 open to eligible people

Showing trials for
  • Two Different Doses of Alpha1-Proteinase Inhibitor Subcutaneous (Human) 15% in Participants With Alpha1-Antitrypsin Deficiency

    open to eligible people ages 18-80

    The purpose of this study is to evaluate the safety and tolerability of 72 milligrams per kilogram (mg/kg) and 180 mg/kg Alpha-1 15%, administered as a single-dose subcutaneous (SC) infusion and subsequently as weekly SC infusions over 8 weeks in participants with Alpha1-Antitrypsin Deficiency (AATD).

    open to eligible people ages 18-80

    Phase 2 study to compare INBRX-101 to plasma derived A1PI therapy in adults with AATD emphysema

  • 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

    open to eligible people ages 18-75

    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 and liver biomarkers (substances in the blood that the body normally makes and help show if liver function is improving, staying the same, or getting worse) as well as to check for side effects in participants treated with fazirsiran compared with those who received placebo. Participants will either receive fazirsiran or placebo. Liver biopsies, a way of collecting a small tissue sample from the liver, will be taken twice during this study.

  • Learn About the Safety of Fazirsiran and if it Can Help People With Alpha-1 Antitrypsin Liver Disease With Mild Liver Scarring (Fibrosis)

    open to eligible people ages 18-75

    The liver produces a protein called alpha-1 antitrypsin (AAT). AAT is normally released into the bloodstream. In some people, the liver makes an abnormal version of the AAT protein, called Z-AAT. Making an abnormal version of the AAT protein can result in liver disease as Z-AAT builds up in liver cells, which leads to liver problems such as liver scarring (fibrosis), continuing liver damage (cirrhosis), and eventually endstage liver disease. Fazirsiran is a medicine that reduces the creation of the Z-AAT protein and thus the build-up of this abnormal protein in the liver. People with this type of liver disease who already have mild liver scarring will take part in the study. They will be treated with fazirsiran or a placebo for about 2 years. This study will check the long-term safety of fazirsiran, whether participants tolerate the treatment and if there are any effects on liver scarring. A liver biopsy, a way of collecting a small tissue sample from the liver, will be taken twice during the study.

  • Learn About the Long-Term Safety of Fazirsiran and if Fazirsiran Can Help People With Alpha-1 Antitrypsin Liver Disease

    Sorry, in progress, not accepting new patients

    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 are currently taking part in or have completed previous fazirsiran studies (AROAAT2001 [NCT03945292] or AROAAT2002 [NCT03946449]) can continue to receive fazirsiran in this study. Participants will receive fazirsiran every 3 months for almost 2 years and will then be followed for an additional 6 months. 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.

  • Alpha-1 Antitrypsin Deficiency Adult Liver Study

    Sorry, in progress, not accepting new patients

    The investigators hypothesize that there is liver injury (inflammation, fibrosis, cirrhosis) in adults with Alpha-1 Antitrypsin Deficiency (AATD), which is asymptomatic, under-recognized, and undiagnosed. In addition, the investigators believe that the genetic and environmental factors that play an important role in the development of alpha-1 antitrypsin (AAT) liver disease, can be identified by comparing a cohort database of clinical disease information to linked biospecimen and DNA samples.

  • Alpha-1 Antitrypsin Disease Cohort: Longitudinal Biomarker Study of Disease

    Sorry, in progress, not accepting new patients

    Alpha-1 Anti-trypsin Deficiency (AATD) is a genetic disease with lung and liver disease presentations. The purpose of this study is to examine the density of the lung as measured by chest computed tomography (CT) and determine if existing emphysema predicts changes in the rate of subsequent emphysema or changes in CT, serum or plasma biomarkers of interest. The overarching goal is to develop biomarkers that can be used in interventional trials since lung function changes do not typically inform disease progression in AATD.

  • Longitudinal Study of Genetic Causes of Intrahepatic Cholestasis (LOGIC)

    Sorry, currently not accepting new patients, but might later

    Cholestasis is a condition in which bile is not properly transported from the liver to the small intestine. Cholestasis can be caused by an array of childhood diseases, including the genetic diseases Alagille syndrome (ALGS), alpha-1 antitrypsin (a-1AT) deficiency, bile acid synthesis and metabolism defects, and progressive familial intrahepatic cholestasis (PFIC) or benign recurrent intrahepatic cholestasis(BRIC). This study will investigate the natural history and progression of the four previously mentioned cholestatic liver diseases to provide a better understanding of the causes and effects of the diseases.

  • PiMZ Longitudinal Cohort (PiMZ Logic)

    Sorry, not yet accepting patients

    Alpha-1 Anti-trypsin Deficiency (AATD) is a genetic disease with lung and liver disease presentations. Presentations are variable in the heterozygous population, the most predominant genotype being PiMZ. The purpose of this study in PiMZ heterozygous patients is to examine the density of the lung as measured by chest computed tomography (CT) and determine if existing emphysema predicts changes in the rate of subsequent emphysema or changes in CT, serum or plasma biomarkers of interest. The overarching goal is to develop biomarkers pertinent to the PiMZ patient that can be used in interventional trials since lung function changes do not typically inform disease progression in AATD.
