Innovation in pharmaceutical therapeutics is critical for the treatment of serious diseases with unmet medical need. To accelerate the approval of these innovative treatments, regulatory agencies throughout the world are increasingly adopting the use of expedited pathways and collaborative regulatory reviews. These pathways are primarily driven by promising clinical results but become challenging for Chemistry, Manufacturing, and Controls (CMC) information in regulatory submissions.

Recent advancements in data engineering, data science, and secure cloud storage can transform the current state of global Chemistry, Manufacturing, and Controls (CMC) regulatory activities to automated online digital processes. Modernizing regulatory activities will facilitate simultaneous global submissions and concurrent collaborative reviews, significantly reducing global licensing timelines and variability in globally registered product details. This article describes advancements made within the pharmaceutical industry from theoretical concepts to utilization of structured content and data in CMC submissions.

The following analytical methods have been used to identify and quantify degradation products in an E. coli expressed human immunoglobulin G Fc fusion protein in both liquid and lyophilized forms: two-dimensional AEX/RP/MS, limited proteolysis followed by LC/MS, and tryptic digestion followed by LC/MS/MS. After aging in a potassium phosphate pH 7.

Article Synopsis
  • A novel method was developed to analyze post-translational and chemical modifications in high molecular weight therapeutic proteins, specifically monoclonal antibodies and peptide-Fc fusion proteins, using established techniques.
  • The process involved limited proteolysis with endoproteinase Lys-C, which targeted a specific lysine residue, yielding smaller fragments that were then separated and characterized via reversed-phase HPLC and mass spectrometry.
  • This combined approach offered faster sample preparation and analysis while improving resolution in detecting various modifications, like methionine oxidation and carbohydrate chains, compared to traditional peptide mapping.
