However, with advancements in genetic testing and increased awareness of the disease among healthcare providers, early diagnosis has become more feasible. Early detection allows for timely intervention, which can significantly improve patient outcomes. In addition, as more organizations and healthcare providers recognize the importance of screening for AATD, especially in at-risk populations, the global awareness surrounding the disease is increasing, thus boosting market growth.

• Replacement Therapies: The most common treatment for AATD is augmentation therapy, which involves the intravenous infusion of purified human alpha-1 antitrypsin protein to increase levels of AAT in the bloodstream. Several companies have developed and launched AAT augmentation therapies, including Prolastin-C, Aralast NP, and Zemaira, all of which have received approval from the U.S. Food and Drug Administration (FDA). These therapies are particularly beneficial in preventing or slowing the progression of lung diseases, including emphysema. As more treatment options become available, and new therapies with improved efficacy are developed, the market for augmentation therapy is expected to grow significantly.

• Gene Therapies and Gene Editing: One of the most promising advancements in the treatment of AATD is the development of gene therapies aimed at correcting the underlying genetic defect. Companies are exploring gene editing techniques, such as CRISPR-Cas9, to potentially treat AATD at the molecular level. By targeting the defective gene responsible for the condition, researchers hope to offer a long-term, possibly permanent solution for individuals with AATD. While gene therapy for AATD is still in the early stages, successful clinical trials could revolutionize treatment and significantly boost the market for AATD therapies in the coming years.

• Government and Regulatory Support: Governments and regulatory bodies worldwide have been supportive of efforts to improve the diagnosis and treatment of AATD. This is evident through various policies that encourage the development of orphan drugs, providing incentives for pharmaceutical companies to invest in rare disease research. For instance, the Orphan Drug Act in the United States grants regulatory and financial incentives to encourage the development of drugs for rare diseases like AATD.
