The market is experiencing significant growth due to several factors. The rising incidence of PID, coupled with greater awareness among healthcare professionals and the public, is driving demand for effective treatments. Advances in biotechnology, such as innovative gene therapies and biologics, are expanding the available treatment options and improving patient outcomes. Additionally, increased research funding is fueling the development of new therapies, further propelling market expansion and offering enhanced management strategies for these complex disorders.

Primary immunodeficiencies (PIDs) affect over 6 million people worldwide, with a significant number-70-90%-remaining undiagnosed. The prevalence of PIDs is about 1 in 10,000 people globally, though this figure is likely an underestimate due to missed diagnoses. For instance, in France, the prevalence is reported to be 4.4 cases per 100,000 inhabitants. The vast majority of PIDs are not diagnosed promptly, which can lead to increased vulnerability to infections, autoimmunity, and other serious health issues. The challenge of diagnosing PIDs is compounded by the wide range of symptoms and the variety of PID types, making early and accurate identification critical but often difficult. The high prevalence and significant undiagnosed rate of primary immunodeficiencies highlights a substantial market opportunity. As awareness and diagnostic tools improve, demand for advanced treatments and care solutions is expected to drive substantial growth in the PID industry.

In April 2023, Irish Primary Immunodeficiencies Association (IPIA) endorsed a new position statement from IPOPI advocating that primary immunodeficiency diseases (PIDs) causing significant disease burden should be recognized as disabilities. This recognition would ensure that affected patients receive long-term financial and practical assistance. The statement received support from various PID organizations. IPIA forwarded this statement to Ireland's Health Minister to push for official recognition of PIDs as disabilities, aiming to improve patient support and public awareness. Endorsing IPOPI’s statement for recognizing PIDs as disabilities boosts industry growth by increasing awareness, attracting funding, expanding treatment options, and fostering industry collaboration. This recognition leads to greater demand for specialized healthcare services and investments in PID research and support.

Furthermore, in June 2024, Nicholas L. Hartog, MD, Fellow of the American Academy of Allergy, Asthma & Immunology (FAAAAI), and FACAAI emphasizes the critical role of genetic testing in diagnosing primary immunodeficiencies (PIs). With over 450 monogenic primary immunodeficiencies, precise genetic testing is essential for distinguishing these conditions and guiding treatment. Despite challenges such as insurance coverage and interpreting results, genetic testing offers definitive diagnoses and improves patient management. Clinicians should test for PIs in cases of common variable immune deficiency (CVID) or unexplained symptoms. Programs like navigate APDS support access to testing and counseling, emphasizing the need for genetic testing as a best practice in primary immunodeficiency care. Advancements in genetic testing for primary immunodeficiencies (PIDs) are set to drive industry growth by improving diagnostic accuracy and reducing misdiagnoses.
