Summary

Sandra Gabelli, Executive Director at Merck, presents how structural biology has transformed pharmaceutical R&D, using the development of enlicitide (MK-0616) as a case study. She outlines the evolution from X-ray crystallography to a multi-technique platform including cryo-EM and micro-ED. The talk covers the entire pipeline: target identification, hit finding, lead optimization, and clinical development. Key points include the structural characterization of PCSK9 and its interaction with LDL receptor, the design of a macrocyclic peptide inhibitor, and the use of structure-based drug design to improve potency and stability. The presentation also highlights the role of biocatalysis in scaling up synthesis, with 13 evolved enzymes supporting commercial production. Clinical trial results show significant LDL reduction, and the drug is positioned as an oral alternative to antibodies. The talk concludes with a Q&A session addressing topics like oral absorption, AI integration, and blood-brain barrier challenges.
