Situation

Each clinical trial site onboarded required an analyst to hand-review a 200–800 page regulatory binder. Average time per site: 40 minutes at best, 90 when things went wrong.

Three vendors had pitched AI document solutions. All three demos looked impressive on the one-page sample and fell apart on a real binder.

What we did
  1. Stood up a labeled evaluation set of 180 real binders spanning three therapeutic areas. Defined success as “≥ 98% field-level precision, zero silent failures.”
  2. Ran the three vendor tools through the eval. All three failed the silent-failure criterion within 40 documents.
  3. Designed an internal pipeline: frontier LLM for extraction, deterministic schema validation, a two-stage human-in-the-loop for anything flagged low-confidence, and a versioned audit log.
  4. Paired with their engineering team to build it in 9 weeks. Sat in on the compliance review and rewrote the workflow diagrams until the Quality officer signed off.
Outcome
  • Time per site from 40 minutes to under 4, end-to-end, including QA.
  • Zero silent-failure incidents in first 1,100 sites processed on the new system.
  • Analyst headcount held flat while site volume grew 3.2× over the engagement.
  • Compliance review documented as a reference workflow for the company’s SOC 2 audit.
