Much fanfare has surrounded the Next Major Version (NMV) of eCTD or eCTD 4 since the group I chaired formed in 2005 and developed initial requirements for the standard. You’ve likely sat in on eCTD 4 presentations at industry conferences and heard secondhand of the deliberations, ballots and revisions going on behind the scenes. In short, we’ve all been waiting for things to happen. Well, things have happened. As a member of the Expert Working Group (EWG) first tasked with developing eCTD 4, I’m proud to report that agencies, vendors and sponsors in each ICH region can get started on implementation. ICH announced that it had reached Step 4 and adopted a harmonized guideline on the eCTD 4 Implementation Package for Modules 2 through 5. Let’s review some of the key concepts of eCTD 4 to get an idea of what will change when this standard is implemented down the road.
The true challenge of eCTD migration is your impact analysis (i.e. downtime, architectural changes and environmental changes) and determining whether or not your selected vendor supports unwritten Agency rules. Bear in mind that subtle differences exist among vendors who have implemented eCTD systems. You need to ensure that your chosen vendor has experience migrating submissions, not only from your existing system, but from all systems that generated eCTD that you now have to manage.
A number of sponsors have recently inquired as to the proper use of the modified-file attributes (operators) when using Study Tagging Files (STFs). Our research has yielded a number of helpful findings on the subject.
The Lifecycle Management section (page 10) of the latest ICH guidance on eCTD Backbone Files Specification for Study Tagging Files incorrectly states that the modified-file attribute of “append” is used to control lifecycle operations of that STF. While the documentation is wrong we don’t expect a timely update.
The Australian Therapeutic Goods Administration (TGA) appears ready to proceed with a pilot program that will pave the way for full adoption of eCTD submissions.
GlobalSubmit recently held an educational webinar on the Understanding the New FDA Validation Criteria. The purpose of the webinar was to provide an overview of the US FDA’s draft version of the new “Specification for eCTD Validation Criteria,” which outlines many of the new error conditions that the FDA will be checking for in the next version of its validation software. During the webinar, facilitated by Daniel Clark, Sr. Manager,...
