Consolidated Stability Testing Guidance
The FDA released a draft guidance called “Q1 Stability Testing of Drug Substances and Drug Products” that consolidates prior ICH stability guidances Q1A(R2), Q1B, Q1C, Q1D, Q1E, and Q5C (published November 2003; March 1996; May 1997; January 2003; June 2004; and July 1996). The draft guidance outlines stability data expectations to support drug product marketing, marketing authorization applications, and, where applicable, drug master files.
New Guidance for Vaccines and Advanced Therapies
The revision adds stability-related guidance for product categories that were not previously covered, including advanced therapy medicinal products, vaccines, and other complex biological products including combination products. Companies working with these product types now have stability testing guidance included in this draft.
Internationally Harmonized, Flexible Testing Approach
The draft guidance, prepared under the International Council for Harmonisation (ICH), is intended to provide an internationally harmonized approach to conducting and presenting stability testing data. It also states that alternative, scientifically justified approaches may be used when warranted by scientific considerations and the characteristics of the data being evaluated.
