BAFF- and APRIL-targeted Therapies Epidemiological Trends

The epidemiological landscape reveals concerning increases in autoimmune disease prevalence across multiple indications where BAFF/APRIL targeting shows therapeutic promise. IgA nephropathy, lupus nephritis, systemic lupus erythematosus, Sjögren's syndrome, and myasthenia gravis represent key target populations demonstrating elevated BAFF and APRIL expression levels. Regional variations persist, with higher diagnosed prevalence rates observed in developed markets compared to emerging economies, though this disparity is narrowing due to improved diagnostic capabilities and healthcare infrastructure development.

Aging populations in major markets are expected to amplify autoimmune disease incidence, as many of these conditions typically manifest in middle-aged adults. The demographic shift toward older populations, combined with improved disease recognition and diagnostic accuracy, is creating expanding patient populations suitable for BAFF/APRIL-targeted interventions. Despite diagnostic improvements, significant underdiagnosis remains in resource-limited settings, where access to advanced biomarker testing and specialized care continues to present barriers to optimal patient identification.

Gender-specific epidemiological patterns are particularly relevant for BAFF/APRIL-targeted therapies, as many autoimmune conditions disproportionately affect women. This demographic concentration influences market dynamics, treatment accessibility considerations, and clinical trial design strategies across the therapeutic development pipeline.
