WHAT IS CTD? Applicationformat CTD IS A JOINT EFFORT OF 3 REGULATORYAGENCIES: 1.European Medicines Agency (EMEA,Europe), 2.Food and Drug Administration (FDA, USA)and 3.Ministry of Health, Labour and Welfare (MHLW,Japan). The CTD is a set of specifications for a dossier for the registration of medicines (TGA) CTD is an internationally agreed well structured common format for the organization of the technical requirements that is to be submitted to the regulatory authority as an application for the registration of pharmaceuticals for human use in all three ICH regions (U.S.A., Europe and Japan). www.ngsmips.nitte.edu.in 4

WHY CTD? Hurdles put down by the 3 major regulatory authorities. Objective of ICH to prepare the CTD. Reduce the time and resources used to compile applications It will ease the preparation of electronic submissions. To facilitate simultaneous submission in three regions. To facilitate easier exchange of regulatory information and thereby ensure faster availability of new medicines. www.ngsmips.nitte.edu.in 5

MODULES OF CTD It is organized into:- Module 1: General Information Module 2: CTD summaries Module 3: Quality Module 4: Nonclinical study reports Module 5: Clinical study reports www.ngsmips.nitte.edu.in 6

GUIDANCE FOR THE INDUSTRY Divided in 4 guidance document www.ngsmips.nitte.edu.in 21

CONCLUSION Whilst the realization of the CTD took many years, there is now a common format for the submission of Marketing Authorizations Applications across the three ICH regions - Europe, Japan and the USA. This should facilitate pharmaceutical companies to make simultaneous filings in the ICH regions as it will eliminate the extensive work previously required to convert, for example, a US dossier to an EU dossier and vice versa. www.ngsmips.nitte.edu.in 22
