Commentary: Current Perspectives on the Aggregation of Protein Drugs

  • Elizabeth M. ToppEmail author
Commentary Theme: Aggregation and Interactions of Therapeutic Proteins

Protein drugs have revolutionized the pharmaceutical industry, offering new treatments for serious diseases. Since the first recombinant protein drug, Eli Lilly’s Humulin®, was approved 30 years ago (1), protein drugs have grown from esoteric specialty products to a major drug class. Of the 20 top selling drugs in the USA in the third quarter of 2012, nine are proteins. Despite these successes, the inherent instability of protein molecules remains an impediment to their development and to their safety and efficacy. One of the most serious types of instability is aggregation, the self-association of native protein through covalent and/or non-covalent interactions. Protein aggregates have been associated with increased or decreased drug potency and with an increased potential for immunogenic side effects, which can be life-threatening. In this themed issue of the AAPS Journal, we have assembled research and review articles that address the aggregation of therapeutic proteins. The issue...
