ESTRI (M2, E2B, M8)

The International Conference on Harmonisation (ICH) Multi-disciplinary Group 2 (M2) Expert Working Group (EWG) was established during the 1994 ICH Meeting in Brussels to facilitate international electronic communication by evaluating and recommending open and non-proprietary - to the extent possible - Electronic Standards for the Transfer of Regulatory Information (ESTRI) that will meet the requirements of the pharmaceutical companies and regulatory authorities. 

Due to the information technology (IT) nature of the topic, some of the activities of the M2 EWG result in Recommendations. These Recommendations do not undergo the formal ICH step process in order to allow flexible change as both science and technologies evolve. They are agreed in the EWG, signed by all parties of the EWG, and are approved and signed off by the ICH Steering Committee within the M2 Recommendation Notebook. The Recommendations page was last updated August, 2016. 

The first Specification developed by the M2 EWG to follow the Step process was the Individual Case Safety Report (ICSR), created as the electronic message for the ICH E2B(R2)M step 4 document version 4.4, Data Elements for Transmission of Individual Case Safety Reports. The Message Specification for E2B(R2) ICSR page was last updated on October 25, 2005. A revised specification was provided for public awareness on June 26, 2009. It was open for comment until 22 July 2009. A further revision to the specification was provided for feasibility testing on July 26, 2010.

An Implementation Guide for Electronic Transmission of Individual Case Safety Reports, E2B(R3) Data elements and Message Specification reached step 4 in November 2012 and further editorial corrections were made by the E2B(R3) working group for publication. E2B(R3) is the first topic collaborating with Standard Development Organisations. The E2B(R3) Implementation Guide web page was last updated in July, 2017. 

The second Specification developed by the M2 EWG was the Electronic Common Technical Document (eCTD) created as the electronic message for the Common Technical Document developed by the M4 EWG. The eCTD page was last updated August, 2017. 

The most recent Specification developed by the M2 EWG is the Study Tagging File (STF) Specification. The STF is supplemental to the eCTD. The STF page was last updated August,2017.

The ICH M8 Expert Working Group (EWG) developed the ICH eCTD v4.0 to improve robustness, flexibility and long term stability of the message. The eCTD v4.0 page was last updated December, 2017. Updated

eCTD 4.0 

The ICH M8 Expert Working Group (EWG) developed the "Specification for Submission Formats for eCTD" to implement the use of a harmonised file format for eCTD.  The Submission Formats page was last updated January, 2017.
