The ICH Q11 Guideline on Development and Manufacture of Drug Substances (Chemical Entities and Biotechnological/Biological Entities) reached Step 2 of the ICH Process in May 2011 and now enters the consultation period (Step 3).

This new guidance describes approaches to developing process and drug substance understanding and also provides guidance on what information should be provided in CTD sections 3.2.S.2.2 – 3.2.S.2.6.
