This therapy is a new approach to treating AATD. The goal is to replace the missing or defective AAT protein in patients with AATD. This is done by introducing a new, functional copy of the AAT gene into the patient's cells.
Stem Cell Therapy:
This therapy is a new treatment for AATD. This approach involves using stem cells to repair or regenerate damaged lung tissue. In some cases, stem cell therapy may replace missing AAT protein. Like gene therapy, stem cell therapy is still in the early stages of development.
Small Molecule Therapies:
Small molecule therapies are another area of active research for AATD. These target specific components of the disease pathway, such as reducing inflammation in the lungs or targeting specific enzymes involved in the breakdown of lung tissue. Several such drugs are currently in development, and early clinical trials have shown promising results.
Augmentation therapy is a well-established treatment for AATD. It involves regularly infusing patients with purified AAT protein to replace the missing or defective protein. Although this therapy can help slow the progression of the disease and improve lung function, it is not a cure. Additionally, the infusion process can be time-consuming and expensive, and some patients may experience allergic reactions to the infused AAT protein.
Lung transplants are a treatment option for patients suffering from severe AATD experiencing end-stage lung disease. Although lung transplants can be life-saving, they are not always feasible due to limited donor availability and the risks associated with any major surgery. Additionally, because AATD is a genetic condition, lung transplantation does not address the root cause of the disease, and patients may still develop lung disease in their new lungs.
Although there is no cure for AATD, researchers are progressing in developing new and innovative treatments for this debilitating disease. From gene therapy and stem cell therapy to small molecule therapies and augmentation therapy, there are many promising new directions in AATD research.
