Introduction

Autoimmune diseases occur when the immune system mistakenly attacks healthy tissues, leading to chronic inflammation and organ damage. Therapeutic approaches include biologics, immunosuppressants, targeted small molecules, and supportive therapies aimed at controlling immune response and preventing disease progression. In Taiwan, autoimmune diseases represent a growing public health burden due to genetic, environmental, and lifestyle factors. Management focuses on long-term disease control, symptom reduction, and quality-of-life improvement. Advances in immunology have enabled development of targeted therapies with improved efficacy and safety. As survival and disease duration increase, autoimmune disorders are increasingly managed as lifelong conditions.

Future Outlook

By 2032, the autoimmune disease therapeutics market in Taiwan will increasingly shift toward personalized and mechanism-specific treatments. Broader adoption of next-generation biologics and oral targeted therapies is expected. Precision medicine approaches based on biomarkers and disease phenotyping will improve treatment selection. Biosimilar penetration will expand, improving access while reducing costs. Combination and sequential therapy strategies will gain importance in refractory patients. Overall, the market will evolve toward more durable disease control with improved long-term safety profiles.
