Abstract

This perspective from the Synthetic Peptide Working Group of the International Quality Consortium Drug Substance Leadership Group discusses the selection of regulatory starting materials (RSMs) for peptide manufacture. Given the ubiquity of solid phase peptide synthesis (SPPS), it has been common practice to simply default to individual amino acids or dipeptides as RSMs. However, as the field of synthetic peptide research has grown and new synthesis technologies have been more widely adopted, this team proposes that there are cases where significant scientific and technical justification exists to consider larger peptide fragments as RSMs which remain consistent with ICH Q11. This framework would provide greater flexibility and support for the adoption of new and superior peptide synthesis technologies, increasing manufacturing process and supply chain robustness and offering opportunities for industry to address sustainability challenges inherent to current practices in synthetic peptide manufacture.
