Since the introduction of insulin almost a century ago, more than 80 peptide drugs have been approved for a wide range of diseases. This Perspective summarizes trends in peptide drug discovery, emphasizing lessons from earlier approaches as well as emerging strategies such as integrated venomics and peptide-display libraries. It also analyses the remaining challenges and the pharmaceutical landscape in which peptide drugs are particularly valuable.
