SDTM Annotation Agent

H1ST-AI-DBD-001 · Task 1.5

SDTM shouldn't be a downstream scramble

When mapping is disconnected from design, conformance becomes something you chase instead of something you have. The SDTM Annotation Agent maps CRF fields to SDTM domains and variables automatically, produces the annotated CRF and Define.xml, and validates against SDTM IG v3.4 — so submission mapping is built in at design time and arrives Pinnacle 21-clean, not bolted on and reworked later.

The grind you know

SDTM shouldn't be a downstream scramble

By the time SDTM mapping lands on your desk, the CRF design that shapes it is long finished — so you're reverse-engineering conformance the design should have carried from the start. Annotating CRFs and hand-building Define.xml is slow, exacting work, and the findings that surface here trace back to decisions made weeks ago, when they would have been easy to fix.

How it works

  1. 1

    Read the CRF design

    The agent takes the CRF fields and study standards as input.

  2. 2

    Map to SDTM

    Fields are mapped to SDTM domains and variables with controlled terminology applied.

  3. 3

    Annotate and validate

    It outputs the annotated CRF and Define.xml and validates clean in Pinnacle 21.

Capabilities

What it takes off your plate

Domain mapping engine

Maps CRF fields across all 35+ SDTM domains (DM, AE, CM, LB, VS, EG, and more) with ML-based field matching.

Annotated CRF + Define.xml

Generates the annotated CRF and a Define-XML v2.1 file conforming to the CDISC standard, with variable attributes and origins.

Controlled terminology

Integrates CDISC controlled terminology packages and manages study-specific extensions.

Pinnacle 21 validation

Validates annotations against SDTM IG v3.4 rules through Pinnacle 21 so mappings are conformant before data flows.

What you get

  • SDTM domain mappings across 35+ domains
  • Annotated CRF (aCRF)
  • Define-XML v2.1 file
  • Pinnacle 21 conformance report

In practice

What this looks like on a real study

Where the agent shows up in the day-to-day of a live trial — the moments the grind usually lives in.

Mapping lands after design is frozen

By the time SDTM mapping reaches you, the CRF design that shapes it is long finished and you are reverse-engineering conformance. The agent maps CRF fields to SDTM domains at design time, so the annotation is built in rather than reconstructed weeks later.

Building Define.xml by hand, again

Hand-assembling Define.xml with variable attributes, origins, and derivations is exacting, slow work. The agent generates the annotated CRF and a conforming Define-XML v2.1 file together, with controlled terminology applied, so you review rather than build from scratch.

Chasing a Pinnacle 21 finding

A conformance finding at submission time traces back to a mapping decision made weeks ago, when it would have been cheap to fix. The agent validates annotations against SDTM IG v3.4 through Pinnacle 21 before data flows, so mappings arrive clean instead of needing rework.

Peace of mind

Built to the standards inspectors expect

Every output is generated inside a validated, audit-ready platform, kept under human-in-the-loop control, and mapped to the regulatory and CDISC standards this agent supports.
