Study Tagging Files: What’s the Right Duration for Study Metadata?

When submitting nonclinical study reports in regions using Study Tagging Files (STF), the duration of the study is one common piece of metadata that must be provided. The ICH eCTD STF Specification provides three options to choose from – short, medium, and long. But the ICH eCTD STF Specification doesn’t define the time periods covered by these three duration options.

Dissecting eCTD 4

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.

How Unwritten Agency Rules Affect eCTD System Migration

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.

The Undocumented STF Lifecycle Management

The Undocumented STF Lifecycle Management

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.
