The methodology that makes regulated AI inspection-defensible.

PQIOS is the operating system I run for AI quality governance in regulated life sciences. Pharmacy already has a fifty-year vocabulary for absorbing agents that bring possibility and vulnerability in the same step. PQIOS translates that vocabulary forward — modified for non-deterministic outputs, agentic workflows, and the regulatory regimes that just finalised.

What this platform talks about.

Forward to governance

Governance is the focal point — the structure that makes quality survivable. Behind it, three domains of depth: bioanalytical, bioequivalence, clinical trials. Each domain is read through four sub-areas: operations · technical · regulatory · market. Behind that, four areas any reader comes from: academic, research, industry, business. Many inputs · one synthesis.

The four-layer stack.

From substrate to vector

PQIOS organises around four layers. Each layer is built on the one below it. None of the layers is optional. The combination is what makes the stack defensible against the failure modes regulated AI deployment actually produces — not against theoretical risk, but against the audit trail that an FDA inspector or an EMA assessor will read in three years.

/ Layer 01
Quality · Governance · Compliance.
The substrate layer. GxP frameworks · 21 CFR Part 11 · ICH M10/M11 · ALCOA+ · ISPE GAMP 5 Second Edition · draft EU GMP Annex 22 (in consultation 2025). The core vocabulary regulators in major markets expect to recognise in documents related to regulated systems.
substrate
/ Layer 02
Three operational domains.
Bioanalytical method validation · bioequivalence study oversight · clinical trial operations. Production-floor depth across analytical platforms, regulatory regimes, study lifecycles, and the matrices in which the science actually lives.
domain depth
/ Layer 03
Methodology: PQIOS as policy.
Where the substrate and the domains compose into machine-executable governance. PQIOS is the policy layer · the spec a fleet of agents reads to know what regulator-grade output looks like, and what does not.
IP
/ Layer 04
AI & technology vector.
The execution layer. EU AI Act Annex III high-risk obligations (applicable 2 Aug 2026) · FDA AI-Enabled Device Software Functions draft guidance (Jan 2025) and related · Predetermined Change Control Plan (PCCP, FDA final guidance Federal Register 4 December 2024, FR 2024-28361) · validation of non-deterministic systems · agentic workflows · MCP-standard tool ecosystems. The vector iFeed is immunising against and operating with, in the same step.

"PQIOS is the policy layer. The substrate is what the policy is defending; the agents are what the policy is orchestrating. None of the three works without the other two." — iFeed methodology note

The three operational domains the methodology covers.

Domain depth
Domain 01

Bioanalytical.

LC-MS/MS · LBA · hybrid platforms · PK/PD substrate · biomarker quantification · the analytical spine of every BE, biomarker, immunogenicity, and PK study. Production-floor depth across method validation, transfer, and regulator-facing dossier work.

ICH M10FDA BMV 2018EMA GLBIVLC-MS/MSLBA
Domain 02

Bioequivalence.

Crossover · RSABE · NTI products · CI 0.80–1.25 · ICH M13A · regulatory frameworks across FDA, EMA, MHRA, HPRA, CDSCO, WHO PQ. The regulator-facing spine of generic and biosimilar approval pathways.

ICH M13ARSABENTIPKcrossover
Domain 03

Clinical trials.

Phase I–IV · ICH-GCP · ICH M11 structured-protocol (Step 4 19 Nov 2025) · TMF/eTMF · adaptive designs · decentralised trials · synthetic control arms. The full study lifecycle from start-up to closure.

What the methodology produces.

Output deliverables

PQIOS is not a deck. It is the policy layer for a fleet of agents that produce regulator-grade documentation. The outputs are the same documents pharma quality and regulatory affairs teams have been writing by hand for decades — generated faster, validated continuously, audit-trail-native by design.

RA
Risk classifications.

EU AI Act Annex III risk-tier mapping for AI deployments within scope, designed to be inspector-ready when implemented within the organisation's QMS.

VL
Validation lifecycles.

IQ/OQ/PQ for non-deterministic systems. PCCP architectures for adaptive AI. GAMP 5 Second Edition aligned.

AT
Audit trails.

ALCOA+ enforcement at the architectural level. 21 CFR Part 11 records that survive a Form 483.

CC
Change control.

Adaptive AI change-control plans. Model-update governance. Drift detection feeding back into validation.

SO
SOPs & procedures.

Standard operating procedures generated against the latest published guidance. Regulator-cited references throughout.

CA
CAPA workflows.

Adaptive immunity in operation. Each incident strengthens the next round of validation.

RD
Regulatory dossiers.

Submission-ready documentation. ICH M11 structured-protocol fluent. Cross-jurisdictional alignment.

EC
Effectiveness checks.

Post-deployment effectiveness across the immunity lifecycle. Continuous improvement feedback loop.

The methodology in continuation.

Horizon

The methodology continues to grow as the regulated AI landscape clarifies — every regulator publication, every operational case, every audit observation feeds back into the policy layer through the daily-research engine that iFeed maintains. The methodology is durable because it is built on substrate that does not move quickly. It is current because the substrate is continuously refreshed.

/ Horizon · in continuation

Beyond the working methodology, iFeed is building the surfaces that turn it into accessible practice for the wider community: iFeed Academy — the cohort-learning platform — and a hosted community for practitioners. Both are scaffolded; both surface here as they come online, subject to interest and substrate readiness. See Academy →

/ Cadence note
The methodology is in continuation, not in a release schedule.

The methodology layer here updates as the regulated AI landscape clarifies — every regulator publication, every operational case, every audit observation feeds the policy layer. Updates land in irregular drops, not on a fixed calendar. If a section goes silent for a stretch, the cadence is working as designed; the next visible drop will have substrate behind it.
