73 Clinical Trials for Various Conditions
The main aim of this study is to learn about liver problems caused by the lack of alpha-1 antitrypsin (called Alpha-1 Antitrypsin Deficiency or AATD) in adults when not treated (this is called the natural history of a condition) over 5 years. Other aims are to learn what can predict the AATD-liver condition starting and getting better or worse, describe how this condition is currently being diagnosed and watched in normal hospital care, and describe how the AATD also affects and adult's lung function. Data in this study will be collected to include medical history of a participant, including the date AATD was first identified and/or the date on which the first AATD-related liver or lung problems were diagnosed. At study start and then every year until study end, participants will be asked to completed questionnaires (called patient-reported outcomes or PRO).
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).
The purpose of this study is to investigate the effect of alvelestat (an oral neutrophil elastase inhibitor) on blood and sputum biomarkers in patients with PiZZ, null or rare variant phenotype/genotype alpha-1 anti-trypsin deficient lung disease. Change in a number of different blood and sputum biomarkers related to lung damage, inflammation and elastase activity will be measured over a 12 week period. The effect on lung function and respiratory symptoms will also be measured.
This is a 2-year open-label, multicenter extension of the double-blind, placebo-controlled GTi1201 study. The purpose of this study is to obtain an additional 2 years of safety data for intravenously administered Alpha1-MP 60 mg/kg/week in subjects with alpha1-antitrypsin deficiency (AATD).
Grifols Therapeutics Inc. conducted a multi-center, randomized, double-blind, crossover study to evaluate the safety, immunogenicity, and pharmacokinetics (PK) of Liquid Alpha₁-PI compared to the currently licensed product, Prolastin-C, in subjects with Alpha₁-Antitrypsin Deficiency (AATD).
This is a multi-center, randomized, placebo-controlled, double blind clinical study to assess the efficacy and safety of two separate dose regimens of Alpha-1 MP versus placebo for 156 weeks (i.e., 3 years) using computed tomography (CT) of the lungs as the main measure of efficacy. The two Alpha-1 MP doses to be tested are 60 mg/kg and 120 mg/kg administered weekly by IV infusion for 156 weeks. The study consists of an optional pre-screening phase, Screening Phase, a 156-week Treatment Phase, and an End of Study Visit at Week 160.
This is a study to assess the safety and pharmacokinetics of weekly infusions of 120 mg/kg of Prolastin-C (alpha1-proteinase inhibitor \[alpha1-PI\] \[Human\]), compared to weekly infusions of 60 mg/kg of Prolastin-C in patients with alpha 1-antitrypsin deficiency (AATD).
This is a study of gene therapy to treat alpha-1 antitrypsin deficiency. This study aims to treat AAT deficiency with a single administration of AAV8hAAT(AVL), a gene therapy that codes for an oxidation resistant form of the AAT protein, which if safe and if efficacious, will protect the lung on a persistent basis. We hope to learn the safety/toxicity and initial evidence of efficacy of intravenous delivery of this gene therapy to alpha 1-antitrypsin (AAT) deficient individuals.
The Sponsor is developing KB408, a replication-defective, non-integrating herpes simplex virus type 1 (HSV-1)-derived vector engineered to deliver functional full-length human SERPINA1 to the airways of people with alpha-1 antitrypsin deficiency (AATD) via nebulization. This study is designed to evaluate safety and pharmacodynamics of KB408 in adults with AATD with a PI\*ZZ or PI\*ZNull genotype. Three planned dose levels of KB408 will be evaluated in single dose escalation cohorts. Subjects taking intravenous AAT augmentation therapy are not required to wash out from IV AAT in the low and mid dose cohorts. At the high dose, two cohorts will be conducted in parallel to evaluate patients on and off IV augmentation therapy.
Phase 2 open label extension study to evaluate SAR447537 (INBRX-101) in adults with AATD emphysema
This is an open-label, 2-part, dose-escalating, Phase 1 study of INBRX-101 (rhAAT-Fc). Part 1 will consist of single ascending dose (SAD) administration of INBRX-101 and Part 2 will consist of multiple ascending dose (MAD) administrations of INBRX-101. The planned dosing schedule is IV every 3 to 4 weeks.
This is a Phase 2, multicenter, double-blind, randomized (1:1), placebo-controlled, 12-week, proof-of-concept study to evaluate the safety and tolerability as well as the mechanistic effect of oral administration of alvelestat (MPH966) in subjects with confirmed AATD defined as Pi\*ZZ, Pi\*SZ, Pi\*null, or another rare phenotype/genotype known to be associated with either low (serum AAT level \<11 μM or \<57.2 mg/dL) or functionally impaired AAT including "F" or "I" mutations.
The purpose of the study is to evaluate the safety and efficacy of administering repeated doses of Hyaluronic Acid Inhalation Solution to subjects with Emphysema that have Alpha-1-Antitrypsin deficiency
The objective of this study is to prospectively assess whether there is any interval between first symptom and initial diagnosis that is experienced by patients with newly diagnosed alpha-1 antitrypsin deficiency (AATD) and then to assess whether this diagnostic interval is associated with worsened clinical status at the time of initial diagnosis.
The aim of this study is to test whether aspirin improves endothelial function in alpha-1 antitrypsin deficiency-associated lung disease, measured by pulmonary microvascular blood flow on magnetic resonance imaging (MRI) and with apoptotic endothelial microparticles.
This is a multicenter, randomized, partial-blinded, five-arm, placebo-controlled study of human plasma-derived alpha1-proteinase inhibitor (alpha1-PI) in children (ages 6-11 years old) and teens/adults (ages 12-35 years old) with new onset Type 1 Diabetes Mellitus (T1DM). Currently enrolling ages 12-35 only. Once 25 patients are randomized and data is reviewed enrollment will be opened to the child cohort. The purpose of this study is to evaluate the safety and efficacy of four dosing regimens of human plasma-derived alpha1-PI in T1DM.
Neuromyelitis Optica (NMO) is a rare, devastating demyelinating disease of the central nervous system (CNS) that has different causes and treatments from the more common demyelinating disease multiple sclerosis (MS). Current NMO therapies are nonspecific and have varying and often suboptimal benefit. The investigators will evaluate whether use of alpha1-antitrypsin (A1AT, an FDA-approved medication for patients with congenital deficiency of A1AT associated with emphysema) can benefit acute attacks of NMO, improving patient disability and quality of life.
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.
This project is designed to examine the interaction between the microflora in the lower airway and the concentration of a serum protein called alpha-1 antitrypsin. The hypothesis is that alpha-1 antitrypsin impacts the diversity and content of the lower airway microflora, resulting in a less inflammatory airway. The Specific Aims are: 1. To compare the lower respiratory tract microbiome and virome population diversity and content in age and GOLD stage matched PiZZ individuals not receiving augmentation therapy, PiZZ individuals on augmentation therapy, PiMZ individuals not receiving augmentation therapy, and PiMM individuals with chronic obstructive pulmonary disease (COPD). 2. Determine correlations between bronchoalveolar lavage (BAL) and peripheral blood gene expression patterns and patterns in lung microbial and viral populations across all cohorts. 3. Correlate the presence or absence of computed tomography (CT) bronchiectasis and bronchiolectasis with patterns in the microbiome population diversity and content. 4. To identify and define novel molecular phenotypes of Alpha-1 Antitrypsin Deficiency (AATD) based on computational integration of clinical, transcriptomic, and microbiome data.
We hypothesize that individuals with Alpha-1 Antitrypsin (AAT) deficiency have ongoing liver injury which is not detected by the usual blood tests used to look at liver function. This ongoing liver injury leads to cirrhosis in a significant number of adults with AAT deficiency.
This was a randomized, double-blind, placebo-controlled, dose escalation study to assess the safety and tolerability of 100 mg and 200 mg of inhaled Alpha-1 HC administered once a day for three weeks in subjects aged 18 years and older with cystic fibrosis (CF). The treatment duration in this study was intended to provide multi-dose safety information prior to proceeding to longer durations of exposure.
Alpha-1 antitrypsin deficiency (AATD) is considered a rare genetic cause of chronic obstructive pulmonary disease (COPD) and liver disease. Recent data has suggested that AATD is not as rare as originally thought and undetected AATD may account for COPD in some patients. This study was designed to evaluate the frequency of undetected AATD in a population reporting to academic pulmonary function testing facilities who meet criteria for the diagnosis of COPD. All individuals meeting GOLD criteria for COPD will be consented and offered free testing for AATD. The results will help identify the percent of those with COPD who have undetected AATD.
The primary objective is to determine if the medication Carbamazepine, can be used as a therapy for patients with severe liver disease due to Alpha-1-Antitrypsin Deficiency .
Assessment of the safety and efficacy of intramuscular (IM) administration of a recombinant adenoassociated virus (rAAV) alpha-1 antitrypsin (AAT) vector (rAAV1-CB-hAAT) in AAT-deficient adults at three dosage levels \[6.0 × 10e11, 1.9 × 10e12 and 6.0 × 10e12 vector genome particles (vg) per kg body weight\].

Individuals with a deficiency of alpha-1 antitrypsin (AAT) often develop emphysema. Traditional lung function tests may not be the most accurate way to measure the progression of emphysema. This study will compare high resolution computed tomography (CT) scans to spirometry to measure the progression of emphysema.
Individuals with a deficiency of the Alpha 1-antitrypsin (AAT) protein are at risk for developing emphysema and liver damage. Researchers have developed a way to introduce normal AAT genes into muscle cells so that the AAT protein is produced at normal levels. This study will evaluate the safety of the experimental gene transfer procedure in individuals with AAT deficiency.
OBJECTIVES: I. Establish cell lines from patients with alpha 1-antitrypsin deficiency in order to examine genetic traits that predispose to liver injury.
The purpose of the study is to determine if Liquid Alpha1-Proteinase Inhibitor (Human) (Liquid Alpha1-PI) plus SMT can reduce the proportion of participants dying or requiring intensive care unit (ICU) admission on or before Day 29 or who are dependent on high flow oxygen devices or invasive mechanical ventilation on Day 29 versus placebo plus SMT in hospitalized participants with COVID-19.
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.
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 have taken part in previous fazirsiran studies (AROAAT2001 \[NCT03945292\] or AROAAT2002 \[NCT03946449\]) can continue to receive fazirsiran every 3 months as long as they participate in this study, the study is ongoing or until health authorities in their country approve fazirsiran to be publicly available. 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.
