Despite their life-saving importance, immunosuppressive drugs face significant challenges that restrain market growth and impact patient management.

• Long-Term Toxicity and Adverse Effects: The fundamental challenge is that immunosuppression carries risks. Long-term use is associated with severe side effects, including nephrotoxicity (kidney damage, particularly from CNIs), increased risk of infection (viral, bacterial, fungal), elevated risk of certain cancers (lymphomas, skin cancer), and metabolic disorders (diabetes, hypertension).

• Patient Adherence: Lifelong adherence to complex, often multiple-drug regimens is critical for transplant success. Poor patient compliance due to side effects, cost, or complexity remains a persistent clinical and market challenge, leading to rejection and treatment failure.

• High Therapy Cost and Reimbursement: Next-generation biologics and targeted oral small molecules carry high price tags, creating a substantial economic burden on healthcare systems and patients, particularly where reimbursement is limited, leading to demand for biosimilars to increase market access.
