Biologic drugs, derived from living cells, have revolutionized treatment for chronic conditions, offering better outcomes and fewer side effects. Their development and delivery face unique challenges, including sensitivity to substances in syringe systems and high viscosity. Trends toward self-injection and home care demand innovative delivery systems. Key elements for successful delivery include patient needs, drug efficacy, primary containment, and delivery devices. Human factors and material innovations, like cyclic olefin polymers, are crucial for effective, safe, and user-friendly biologic therapies.
