FDA is Advising Biotech Product Applicants to More Clearly Justify Their Excipient Usage

FDA’s Office of Pharmaceutical Quality (OPQ) is asking biotech product sponsors to fully explain the process used to select excipients and to provide a risk assessment on potential interactions between the excipients and their proteins.

The agency wants to be sure that the biotech manufacturers understand the full ramifications of the way they are using excipients and how the product/excipient interactions differ from their use in the small molecule context.

At a mid-November workshop on “Excipient Quality, Compendial Testing, and Regulatory Impact,” sponsored by USP and held at its Rockville, Maryland headquarters, OPQ Office of Biotech Products (OBP) Acting Applied Biochemistry Lab Chief Ashutosh Rao provided OBP’s perspective on the selection of excipients for biotech products and highlighted some of the problems his office has seen.
