NCT06389877
This is a Phase 1/2, multicenter, open-label, dose-exploration (Phase 1) and dose-expansion (Phase 2) study to evaluate the safety, tolerability, PK/PD, and efficacy of BEAM-302 in adult patients with AATD-associated lung disease and/or liver disease and to determine the optimal biological dose (OBD).
NCT06996756
This is a study of gene therapy to treat alpha 1-antitrypsin (AAT) 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 deficient individuals.
NCT03946449
The purpose of this study is to evaluate the the safety and efficacy of the investigational product, fazirsiran (TAK-999, ARO-AAT), administered subcutaneously to patients with alpha-1 antitrypsin deficiency associated liver disease (AATD).
NCT07152834
Brief Summary: This study aims to find out if a genetic condition called Alpha-1 Antitrypsin Deficiency (AATD) is more common in people who have shortness of breath and signs of airway obstruction on their breathing tests. Alpha-1 antitrypsin (AAT) is a protein that protects the lungs from damage. AATD is an inherited condition where the body does not make enough of this protein, which can lead to lung diseases like emphysema, especially in smokers. Investigators hypothesize that low AAT levels or related genetic mutations may be a contributing factor to airway obstruction in patients complaining of shortness of breath. To test this, investigators will recruit patients from our outpatient clinic who are being evaluated for shortness of breath and are having a standard breathing test (spirometry). Investigators will measure their AAT levels and test for the most common genetic mutations that cause AATD using a small blood sample. Investigators will then compare the AAT levels and genetic results between different groups of patients, such as smokers and non-smokers with and without airway obstruction. Investigators will also see if the severity of a patient's shortness of breath is related to their AAT levels. The goal is to improve the detection of AATD in this patient population, which could lead to better diagnoses and specific treatments for those who have this condition.
NCT04204252
The goal of this clinical trial is to learn if AAT for inhalation, at a dose of 80 mg/day can slow the progression of lung disease in people who have lung disease caused by severe genetic deficiency in Alpha 1 Antitrypsin (AATD). The main question it aims to answer is: • Can daily treatment with Kamada AAT for inhalation at a dose of 80 mg/day prevent or slow lung function worsening ? Lung function will be measured by spirometry. Other questions it aims to answer are: * Can daily treatment with Kamada AAT for inhalation at a dose of 80 mg/day prevent or slow lung density loss ? Lung density will be measured by a CT scan. * Can daily treatment with Kamada AAT for inhalation at a dose of 80 mg/day prevent or slow lung disease from worsening ? Lung disease will be measured using spirometry, lung volume, gas diffusion, six minute walk test, quality of life questionaires and biomarkers. * What medical problems do participants have when taking AAT for inhalation 80 mg/day daily ? Researchers will compare AAT for inhalation to a placebo (a look-alike substance that contains no drug) to see if AAT for inhalation works to treat AAT-deficiency related lung disease. Study participants will receive either AAT for inhalation or placebo for the first two years of the study. During the third and fourth years of the study all participants will receive AAT for inhalation regardless of which drug they received during the first two years. Participants will: * Inhale the study drug every day * Clean and disinfect the nebulizer every day * Document daily symptoms and study drug use in an electronic diary * Visit the clinic for tests and assessments. There are 11 clinic visits during the first two years of the study and 5-6 clinic visits during the third and fourth year, combined. After treatment ends, participants will visit the clinic 3 times in half a year.

Phase 2 study to compare SAR447537 (INBRX-101) to plasma derived A1PI therapy in adults with AATD emphysema
NCT02691611
The investigators hypothesize that environmentally influenced histone modifications regulate AM mediated inflammation, contributing to a variable clinical course of AATD, and may also influence or be influenced by the activity of AAT augmentation therapy.
NCT04174118
This is a research study to test an experimental study drug (belcesiran, also known as DCR-A1AT). This drug is being tested to see if it helps people with a rare condition known as Alpha-1 Antitrypsin Deficiency, or A1ATD. Prior to initiation of this study belcesiran had not yet been tested in humans. All study participants will be randomly assigned to either receive the study drug or a placebo. This will allow for the sponsor to compare the effects of the study drug with that of the placebo. A placebo looks like the study drug but does not contain any of the study drug. The main purpose of the first part of the study is to evaluate the safety profile of the study drug in people who do not have A1ATD. This part of the study will also help find the dose of the study drug that has an acceptable safety profile for testing.

The Registry was established to facilitate research initiatives and promote the development of improved treatments and a cure for Alpha-1.
NCT04966221
This study aims to use novel proton-based MRI techniques to assess lung function and structure in healthy volunteers and patients with chronic obstructive pulmonary disease (COPD) and alpha-1-anti-trypsin deficiency (A1ATD). These novel MRI measures will be compared to matched contemporary clinical diagnostic tools, namely pulmonary function tests (PFTs) and computed tomography (CT) scans. MRI has the advantages of avoiding ionising radiation exposure (unlike CT scans) and can also provide regional measures of lung function (unlike PFTs which provide global measures of function). In addition, these MRI techniques do not require the use of any inhaled or injected contrast agents. Some patients enrolled in this study will be undergoing a lung volume reduction (LVR) procedure as part of their normal clinical care. LVR is an intervention for patients with severe lung disease and hyperinflation. It is a palliative therapy that helps to reduce lung hyperinflation through insertion of small valves in the airway or surgical removal of parts of the lung. This can lead to improvements in symptoms such as breathlessness and improve exercise tolerance due to better functioning of the lung. In this study, we will explore how lung MRI measures can be used to assess patients before and after an LVR intervention. This study will take place at the University of Nottingham in collaboration with Nottingham University Hospitals NHS Trust. The study will last for 3 years and participants will be asked to attend a screening visit (lasting up to 1 hour) and either one or two study visits (each lasting up to 3 hours).

The Alpha-1 Foundation Research Registry is a confidential database made up of individuals diagnosed with severe alpha-1 antitrypsin deficiency (Alpha-1) or the carrier state.
NCT04180319
European Alpha-1 Research Collaboration (EARCO) is a pan-European network committed to promoting clinical research and education in alpha-1 antitrypsin deficiency (AATD). The core project is the pan-European AATD Registry, a collaboration which will offer longitudinal real-world data for patients with AATD. EARCO has a global vision to increase the early diagnosis of alpha-1 antitrypsin deficiency (AATD), understand better the natural history of the disease and ensure optimal access to effective care, placing emphasis on ambitions that serve collective needs of the AATD research community and bringing people with AAT deficiency to the centre of the research environment in a real-world context. The study population will consist of individuals with diagnosed severe alpha-1 antitrypsin deficiency regardless of the clinical expression and severity. The study objectives are: * To generate long-term, high-quality clinical data covering a pan-European population of AATD individuals in all age groups and all stages of disease severity. * To understand the natural history and prognosis of AATD better with the goal to create and validate prognostic tools to support medical decision making. * To investigate the effect of augmentation therapy on the progression of emphysema and to examine its impact on clinical and functional outcomes, such as FEV1, quality of life and mortality in a "real-life" population * To learn more about the course of the disease in patients suffering from severe AATD with genotypes different from Pi\*ZZ We expect to collect detailed information from around 1,000 patients from at least 10 countries during the first year, expanding to 3,000 from more than 25 countries over the 5 years of the CRC and continue a long term follow-up.

Pulmonary rehabilitation (PR) including exercise training is highly effective by improving health-related quality of life, exercise capacity and symptoms in patients with chronic obstructive pulmonary disease (COPD). Therefore, PR is a main component in the management of COPD. In a former study patients with Alpha-1 Antitrypsin deficiency (A1ATD)-related COPD (genotype PiZZ) have been found to show smaller improvements in exercise capacity after a 3-week inpatient PR program compared to COPD patients without A1ATD (genotype PiMM)\[1\]. These between-group differences were mirrored by missing adaptations of the fatigue-resistant skeletal muscle fibre type I in A1ATD patients. This was in contrast to COPD patients without A1ATD who increased the proportion of this fibre type after PR. Myofibre type I is crucial because it enables patients for physical endurance activities (walking, cycling etc.) during their daily life. The aim of this study is to compare the effects of an exercise Training program with high vs. moderate Training intensity in order to find a Training modality which improves Training effects in A1ATD patients.
