Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease: Understanding

Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease: Overview

Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease, is an inherited metabolic disorder in which this protein is absent or defective. The deficiency is caused by mutation in the A1AT protein encoding gene SERPINA1 and is inherited in an autosomal recessive manner. Alpha-1 antitrypsin is a large, 52‐kDa serum glycoprotein and a serine protease inhibitor. AAT is primarily produced in the liver and plays a crucial role in protecting the lungs from inflammation caused by infection and irritants such as tobacco smoke.

Alpha-1 antitrypsin deficiency occurs worldwide, but its prevalence varies by population. This disorder affects about 1 in 1,500 to 3,500 individuals with European ancestry. It is uncommon in people of Asian descent. Many individuals with alpha-1 antitrypsin deficiency are likely undiagnosed, particularly people with a lung condition called chronic obstructive pulmonary disease (COPD). COPD can be caused by alpha-1 antitrypsin deficiency; however, the alpha-1 antitrypsin deficiency is often never diagnosed. Some people with alpha-1 antitrypsin deficiency are misdiagnosed with asthma.

Some people with A1ATD experience no symptoms at all. But in some people it can lead to the development of lung conditions and liver disease. Symptoms of A1ATD Liver disease includes breathlessness during exercise or physical activity, cough that lasts a long time, production of phlegm, wheezing, repeated chest infections, prolonged jaundice, hepatomegaly, cholestasis, muscle wasting and abdominal pain.

In children, A1ATD Liver Disease is the most frequent genetic etiology for pediatric liver disease and transplantation. It is caused by a mutation in chromosome 14, the disease is inherited in an autosomal recessive manner with codominant expression. There are over 100 variants of the alpha-1 antitrypsin (A1AT) gene (SERPINA1), which can be influenced by other genetic and environmental factors, leading to marked variation in the onset and severity of disease. The liver disease associated with A1ATD is a gain-of-toxic function mechanism.

The diagnosis of Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease is confirmed with laboratory analysis. Phenotyping by isoelectric focusing is the gold standard of diagnosis. Although liver biopsy is not required for diagnosis, it may be helpful in difficult cases and/or for prognostication. Anti-human A1AT antibody can also confirm the presence of ATZ globules. Electron microscopy studies can identify multiple globular inclusions within dilated, congested rough ER cisterns, adjacent to secondary lysosomes.

Treatment involves smoking cessation, preventive vaccinations, bronchodilators, supplemental oxygen when indicated, and physical rehabilitation in a program similar to that designed for patients with smoking-related COPD. Augmentation therapy may help slow lung damage. Evolving therapies under research studies for the treatment of A1ATD Liver Disease management includes: Chaperones, Autophagy-Enhancing Agents, Bile Acids as Small Molecule Therapy, Inhibiting Polymerization of ATZ, Gene Therapy and Editing, and Cell Therapy.

Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease Emerging Drugs Chapters

This segment of the Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease report encloses its detailed analysis of various drugs in different stages of clinical development, including phase III, II, II/III I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease Emerging Drugs

• Fazirsiran: Arrowhead Pharmaceuticals

Fazirsiran (ARO-AAT) is a subcutaneous RNAi-based therapeutics, being developed to treat the liver disease associated with alpha-1 antitrypsin deficiency (AATD). ARO-AAT is designed to knock down the hepatic production of the mutant alpha-1 antitrypsin (Z-AAT) protein, the cause of progressive liver disease in AATD patients. Reducing production of the inflammatory Z-AAT protein is expected to halt the progression of liver disease and potentially allow it to regenerate and repair. The product candidate is being co-developed in partnership with Takeda. Currently, the drug is in the Phase III stage of its development for the treatment of Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease.

• Alvelestat: Mereo BioPharma

Alvelestat (MPH966) is an oral drug that is being investigated for the treatment of Alpha-1 Antitrypsin Deficiency-associated Lung Disease (AATD-LD). Alvelestat acts to inhibit the neutrophil elastase enzyme and Mereo believes that it has the potential to help protect people with AATD by slowing progressive lung damage. While AATD may affect both the lungs and the liver, alvelestat’s mechanism of action only addresses lung disease, which is the most common effect of AATD in adults. Other companies are researching the effects of AATD on the liver. Currently, the drug is in the Phase II stage of its development for the treatment of Alpha-1 Antitrypsin Deficiency (A1ATD) Liver Disease.
