Monoclonal antibodies (MAbs) are at the focal point of biologics development. Many of the best-selling drugs are therapeutic MAbs or related proteins (1–2). The combined world-wide sales from MAbs will be nearly US$125 billion by 2020 (3). About 50 MAb products treating a range of diseases have been approved in the United States or Europe. With the large number of MAbs progressing through discovery, biomanufacturers need to accelerate process development and move projects rapidly into clinical manufacturing (4–5). Formulation development, an important aspect of product development, is often on the critical path to successful clinical manufacturing and stability studies, which are essential to investigational new drug (IND) filings. Discussions on leveraging platform processes to shorten process development timelines and save resources often focus primarily on upstream and downstream operations (6–7). Here we describe a rapid platform strategy for formulation development successfully used for MAbs by Patheon Biologics.
