About DARPin Therapeutics
DARPin (Designed Ankyrin Repeat Protein) therapies are a new class of tailor-made protein medicines, based on natural binding proteins, that open new dimensions of multifunctionality and multi-target specificity in drug design. The flexible architecture, intrinsic potential for high affinity and specificity, small size, and high stability of DARPins offer advantages for drug design over other currently available protein-based therapies. DARPin candidates can be radically simple, with a single DARPin unit acting as the delivery vector for a specific target; or multispecific, with the ability to achieve more than five targets, and combine multiple and conditional functionalities into a unique DARPin drug candidate. The DARPin platform is designed as a fast and cost-effective drug discovery engine, producing drug candidates with optimized properties and high production yields. DARPin therapies have been clinically validated in several therapeutic areas and developed through to the registration phase.
