FDA Clarifies ICH Guideline on Selecting and Justifying Drug Manufacturing Starting Materials

Feb. 27, 2017

The draft question and answer guidance covers the implementation of a single section of the Q11 manufacturing guideline — first developed by the International Council for Harmonisation and adopted by the FDA in 2012 — and makes recommendations for the information that should be included in marketing applications.
