WHO Prequalification Programme of Priority Essential Medicines, October 2010, Abu Dhabi, U.A.E. CTD FORMAT – ICH Requirements The CTD is not a “Global Dossier” ! It is an agreed-upon common format for the “modular” presentation of summaries, reports and data Incorporates relevant ICH guidelines It is organized into five sections:  All “modules” harmonized except Module 1 – regional specific  Raw data per regional requirements

WHO Prequalification Programme of Priority Essential Medicines, October 2010, Abu Dhabi, U.A.E. Module 1 Regional Administrative Information Nonclinical Overview Quality Overall Summary Clinical Summary Module 3 Quality Module 4 Nonclinical Study Reports Module 5 Clinical Study Reports Clinical Overview Nonclinical Summaries Not Part of CTD CTD Module 2 NDS Result was the CTD Triangle

WHO Prequalification Programme of Priority Essential Medicines, October 2010, Abu Dhabi, U.A.E. CTD Structure Full dossier contains 5 “Modules” Only Modules 2-5 are “CTD”  Module 1 – region-specific but always included in complete CTD structure  Module 2- All summaries / overviews  Module 3 – CMC (“Quality”)  Module 4 – Preclinical  Module 5 - Clinical
