Data Readiness Knowledge Base

01

Where it fits and where it does not

Use these four checks before committing implementation time.

Use it when: Regulatory applications, amendments, supplements, reports, and master files that must be assembled, validated, transmitted, and reviewed as one traceable dossier lifecycle.
Limits: Module 1, controlled vocabularies, validation criteria, acceptance dates, and forward-compatibility support vary by regulator. ICH and regional packages must be pinned separately.
Best for: Clinical and Preclinical and Regulatory teams working across Harmonize → Exchange.
Maturity: ScalingUsable now, but adoption or tooling is still developing. Pilot the exact stack first.

This view shows the input, the change the standard introduces, and the resulting output.

Readiness gateModule 1, controlled vocabularies, validation criteria, acceptance dates, and forward-compatibility support vary by regulator. ICH and regional packages must be pinned separately.

03

A concrete example

A sponsor assembles clinical, nonclinical, and quality documents plus standardized study data into a version-pinned eCTD v4.0 sequence, applies lifecycle operations, and validates both the ICH core and target-region rules before transmission.

Why it matters: Structured dossier metadata improves indexing, lineage, and review automation, but many payloads remain document-centric and eCTD conformance does not establish scientific quality or model fitness.

04

What it fits with

CDISC supplies regulated study datasets and metadata inside the dossier; IDMP and SPL structure selected product information; regional Module 1 guides constrain the ICH core.

05

Implementation starter

Start with one bounded handoff. Pin, test, and review it before scaling.

Define one handoff, its accountable owner, and the decision eCTD v4.0 must support.
Pin the exact version and companion artifacts: v4.0 · Step 4; ICH IG package 1.6 in FDA's 2026 support table.
Map one representative input to the required standard artifacts.
Test the result against the canonical source and record every exception.
Preserve the source data, mappings, and review evidence before scaling.

06

Test the main limitation

Risk

Module 1, controlled vocabularies, validation criteria, acceptance dates, and forward-compatibility support vary by regulator. ICH and regional packages must be pinned separately.

Test

Run one representative end-to-end pilot and record exactly where eCTD v4.0 loses context, needs an extension, or depends on another standard.

Risk

Machine-readable output may still be unfit for analysis or ML.

Test

Test the output for missing context, provenance, terminology alignment, time leakage, and the intended downstream decision. Structured dossier metadata improves indexing, lineage, and review automation, but many payloads remain document-centric and eCTD conformance does not establish scientific quality or model fitness.
