A draft timeline for the implementation of eCTD v4.0 in the EU was published in the ICH website in January 2022.

The ICH M8 EWG would like to assess the readiness of eCTD v4.0 Vendors and their development and/or readiness to deliver a production ready eCTD v4.0 solution. We request that the eCTD v4.0 Vendor Readiness Survey be completed by September 15, 2019.

To support initial understanding, benefits and challenges of eCTD v4.0 implementation in the EU additional information material was developed.
In a short slide deck here the main aspects from the viewpoint of business management are demonstrated.
In a slightly extended version here also technical aspects are considered to provide a more complete overview.

The key documents for the Electronic Common Technical Document (eCTD) v4.0 Modules 2 through 5 was signed off by the ICH Steering Committee in November 2015 for ICH Step 4.

The ICH M8 Working Group on electronic submission has drafted these documents based on the Regulated Product Submission (RPS) standard established by HL7 in September 2014. This standard defines the message for exchanging regulatory submission information electronically between applicants and Regulatory Authorities.

The XML message provides the ability to describe the contents of the regulatory exchange and all information needed to process the exchange between these two parties. 

The most recent version of the package of relevant documents for implementation is accessible on the ESTRI web page.

The ICH Implementation Guide and the respective set of controlled vocabularies will need to be used in conjunction with the EU Module 1 Implementation Guide and an additional set of EU relevant controlled vocabularies, as the eCTD v4.0 message will be incomplete without all of the contents.

The package from the 1st and 2nd round of public consultations can be downloaded from here.
