Special Report: A World of Difference — Biosimilars and Biobetters Offer Unique Benefits — and Risks

by John Otrompke, with Cheryl Scott and S. Anne Montgomery When the United States Food and Drug Administration (FDA) approved the country’s first ever biosimilar on 6 March 2015, it had been a long time coming. After all, the European Union had approved the first biosimilar in 2006, and a number of others have followed in Europe since then. Still, the approval of biosimilar filgrastim, a recombinant colony-stimulating factor used to offset the complications of chemotherapy, was a welcome step…

Optimization and Scale-Up of HCIC-Based MAb Purification Processes, Part 2

In multistep schemes, hydrophobic charge-induction chromatography (HCIC) has been shown to contribute effectively to clearance of Chinese hamster ovary (CHO) host-cell proteins (CHOPs), DNA, and viruses. When used for capture chromatography, HCIC can provide better aggregate clearance than protein A sorbents can. Chen et al. enhanced clearance of aggregates, CHOPs, and product- related impurities by controlling HCIC based on both pH and the presence of binding-promoting salt in the wash and elution buffers used (1). Taken together with our findings…

Challenges in Implementing Quality By Design: An Industry Perspective

In the fall of 2004, the US Food and Drug Administration (FDA) published a final report entitled Pharmaceutical CGMPs for the 21st Century: A Risk-Based Approach (1). This publication set the groundwork for a prospective risk‑based approach to pharmaceutical product development. It was published on the heels of a November 2003 agreement between the FDA and the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) to develop an internationally harmonized plan for developing…
