The Situation and Problem

In April 2026, FDA issued a warning letter to Purolea Cosmetics Lab after an inspection identified several CGMP violations. One section of the letter specifically addressed the company’s inappropriate use of artificial intelligence in pharmaceutical manufacturing. FDA stated that the firm used AI agents to help create drug product specifications, procedures, and master production or control records intended to comply with FDA requirements.

 

The problem was not that AI was used. The problem was that AI-generated documents were not adequately reviewed to ensure they were accurate and compliant. FDA explicitly stated that, when AI is used as an aid in document creation, the firm must review the AI-generated documents. FDA also noted that overreliance on AI was documented during the inspection.

AI Does Not Carry Regulatory Responsibility

One detail is particularly relevant for regulated teams. When FDA investigators raised the lack of required process validation, the firm reportedly responded that it was unaware of the legal requirement because the AI agent had not told them it was required.

 

For clinical trial organizations, the lesson is clear. AI may support drafting, review, summarization, or analysis. It does not carry regulatory responsibility. Qualified humans remain accountable for the decisions, documentation, and rationale.

Why This Matters for Clinical Trials

Clinical trials operate under different expectations than everyday AI use. Outputs can affect patient safety, data integrity, trial conduct, submissions, and inspection outcomes.

 

For Clinical Operations, QA, Medical Monitoring, Central Monitoring, Data Management, and study leadership, the practical question is no longer whether AI will be used. It is whether teams know how to use it within controlled boundaries.

AI use must be What this means in practice
Approved Teams know which tools may be used
Fit for purpose AI is used only for appropriate tasks
Reviewed Outputs are verified by qualified people
Documented Use, rationale, and review can be reconstructed
Accountable Final decisions remain with humans

The compliance risk is not AI. It is unmanaged AI.

The warning letter should not be read as an argument against AI. It should be read as a warning against uncontrolled reliance.

 

Common risk patterns include:

  • Using public or unapproved AI tools with confidential or sensitive information
  • Treating AI-generated text as verified content
  • Assuming AI will identify all regulatory requirements
  • Using AI outside its validated or intended scope
  • Failing to document human review and decision rationale
  • Allowing teams to apply different standards across functions

 

These are capability issues as much as technology issues.

This is not a single case. FDA and EMA are aligning on one principle: AI must be used with transparency, validation, and human accountability.

A Practical Control Model for AI Use

1

Define the intended use

Clarify what AI is being used for and whether that use is permitted.

2

Confirm the tool and environment

Use only approved, secure, and appropriate systems.

3

Assess the risk

Consider impact on patient safety, data integrity, confidentiality, blinding, and regulatory decisions.

5

Document when required

Record the tool, purpose, review, and final human decision where the impact requires traceability.

4

Review the output

Treat AI output as draft support, not verified evidence.

What Teams Need to Learn

GCP-compliant AI capability is not only about knowing how to prompt a system. Teams need to understand where AI fits, where it creates risk, and where human accountability must remain visible.

 

A useful AI capability baseline should cover:

  • What AI is and what it is not
  • Differences between AI, machine learning, LLMs, reasoning models, and agents
  • Why clinical trial use differs from everyday use
  • Data protection, confidentiality, and blinding risks
  • Validation and intended use principles
  • Human-in-the-loop review
  • Documentation, traceability, and inspection readiness
  • When AI should not be used in a GCP environment

Key Learning

AI can accelerate regulated work, but it cannot absorb regulated responsibility.

 

For clinical trial teams, the defensible position is not “the AI gave us the answer.”

The defensible position is: “We used an approved tool for an appropriate purpose, reviewed the output, documented the rationale, and retained human accountability.”

 

That is why AI capability training is becoming essential for clinical research organizations.

Build a Shared Baseline for Responsible AI Use

MyRBQM® Academy’s AI Essentials for Clinical Trials (GCP-Compliant) eCourse helps clinical teams understand how AI can be used responsibly in GCP-regulated environments.

 

It is designed for professionals in Clinical Operations, QA, Data, Central Monitoring, Medical Monitoring, and study leadership who need a practical baseline before AI use becomes broader, faster, or harder to control.

AI-Driven Predictive Analytics in Risk-Based Monitoring

In modern clinical trials complexity continues to rise — data volumes grow, endpoints broaden, and decentralized elements become the norm. Under ICH E6(R3), sponsors are expected to move from reactive monitoring to oversight that is anticipatory and risk-based. Predictive analytics enables that shift. 

Why it matters

When oversight teams wait for problems to appear — delayed AE reporting, slow site performance, patient drop-out patterns — the cost of correction rises. Predictive analytics lets trial teams detect trends before they become crises: subtle shifts become visible, and intervention windows widen. 

How it works in practice

Metrics such as query rates, lab turnaround times, visit reschedules and enrollment trends are analysed over time. The algorithm identifies and forecasts “what if” scenarios: if current patterns continue, what is likely to happen next? 
This practical capability aligns with E6(R3)’s requirement to document risk-based monitoring logic, decision rationale and corrective action pathways. 

Example in action

A site begins to show a consistent five-day drift in AE submissions. On its own this may not raise an alert. Predictive modelling shows that if the delay trend reaches ten days in two weeks, safety review time will be compromised. The oversight lead contacts the site, uncovers a staffing issue and re-allocates monitoring resources — preventing escalation.This practical capability aligns with E6(R3)’s requirement to document risk-based monitoring logic, decision rationale and corrective action pathways. 

Role of human judgement

Predictive analytics does not replace the clinical or operational decision-maker. It guides where to look, when to act, and how to allocate resources — enabling oversight teams to focus on exception rather than every datapoint.

Predictive oversight elevates operational efficiency, enhances participant safety windows and meets regulatory expectations for traceable risk-based decision-making. It’s not about automating judgment — it amplifies it.
