The rapid and cost-effective production of conventional monoclonal antibodies (MAbs) for clinical trials and commercial supply has contributed toward their wide adoption. Production processes have become more efficient because common purification processes are being used across structurally similar MAbs during key steps of process development and manufacturing. Such successful platform approaches can remove unwanted impurities and are stable across processing conditions, irrespective of the MAb being purified. In addition, they are readily available at the required volume to support large-scale current good manufacturing practice (CGMP) production and can be validated easily. Platform approaches also minimize both the duration and number of steps in downstream processing operations, which contributes significantly to maximizing efficient batch production.
