FDA Diversity Plans Guidance (April 2022) — representative-population parity for AI-driven eligibility

The Guidance sets FDA's expectation that sponsors enroll clinically representative populations. When AI screens eligibility, "representative" becomes a measurement question about the classifier — not just the recruitment plan. A silent exclude-lane differential on the elderly-multimorbid patient group is the shape FDA drafted this Guidance to detect.

What the guidance actually says

"FDA encourages sponsors to enroll participants who reflect the diversity of the population that will use the medical product, if approved … A Diversity Plan should include measurable enrollment goals, operational plans to meet those goals, and a discussion of how the sponsor will monitor progress." FDA Guidance for Industry: Diversity Plans to Improve Enrollment of Participants from Underrepresented Racial and Ethnic Populations in Clinical Trials (April 2022 draft, codified expectations in FDORA 2022)
"Sponsors should describe … the plan to reach enrollment goals, including specific measures for recruitment and retention of participants from underrepresented racial and ethnic populations." FDA Diversity Plans Guidance — monitoring + measurement expectation

What this means in plain English

Two obligations when AI participates in eligibility screening:

  1. Measurable representative-population goals. The Diversity Plan appendix names specific enrollment targets. Those targets are auditable.
  2. Monitoring. "How will the sponsor monitor progress?" AI-driven eligibility monitoring falls to the sponsor — not the clinical-AI vendor whose classifier is being monitored.

An AI classifier that systematically over-routes an underrepresented subgroup to the ineligible_exclude lane is the operational failure mode this Guidance is calibrated against. Retraining timing, recruitment mix, and per-subgroup exclusion rate are all in scope.

What triggers the exposure in the sample

P3 (age 65+, 3+ comorbidities, minority representation) exclude-lane rate rose from 22% baseline to 75% recent. A 53 percentage-point group differential in the wrong direction for a Diversity-Plan target subgroup is precisely the shape a FDA Type C meeting reviewer or EMA scientific-advice rapporteur would flag. The Diversity Plan appendix commitment — "sponsor monitors AI-driven eligibility decisions for representative-population parity across pre-specified subgroups" — is now harder to answer without dated independent evidence.

How does this help me?

The Guidance is the rule. The consequence of NOT having independent evidence of monitoring when FDA raises the Diversity Plan question at the next Type C or pre-NDA meeting is a very different exposure profile.
