Clinical-trial chain-of-custody, proven to the regulator.
A top-5 global pharma needed defensible chain-of-custody and cold-chain integrity across 28 trial protocols.
The programme and figures on this page come from an earlier work by our advisers. The client name is withheld under NDA. Figures are as reported at the time. Named references are available under NDA when you engage.
What they were up against.
Paper chain-of-custody
Custody for trial kits was paper-based and slow to reconstruct for audit.
Cold-chain risk
Temperature excursions risked the loss of high-value batches.
Weak audit readiness
21 CFR Part 11 audit readiness was inconsistent across protocols.
Earlier work by our advisers. Client name withheld under NDA. Client name withheld under NDA; figures as reported at the time. Named references available under NDA. We model your own numbers when you engage.
Independent, tied to a named KPI.
We delivered continuous temperature, shock and location logging with sealed chain-of-custody and 21 CFR Part 11 electronic records, sharing events via EPCIS across 28 protocols.
What the engagement delivered.
- Continuous temperature, shock and location logging
- Sealed chain-of-custody from depot to site to patient
- 21 CFR Part 11 e-records plus EPCIS sharing
Results in this engagement
The stack behind it
Baseline, method, period and what we excluded.
This page describes an engagement our advisers led in earlier roles. The client name is withheld under NDA. Figures are as reported at the time, with published industry sources where noted.
- Baseline: Investigational product custody in logs; reconciliation at monitoring visits.
- Method: Serialized custody events; temperature where required; discrepancy ageing to QA.
- Period: Study depot and selected sites through a monitoring cycle.
- Excluded: Commercial retail RFID averages.
Programme context
Clinical-trial custody needs attributable, contemporaneous location and handoff events for investigational product. Hybrid barcode/RFID with controlled RTLS zones in pharmacies and clinics is typical.
Part 11 validation and role design dominate; accuracy is secondary to auditability.
Outcomes in this engagement and how they were earned
Outcomes: fewer missing kits, faster reconciliation, inspection-ready custody stories.
Lessons from this engagement
Lessons: system of record clarity; no shared logins; train site staff; keep sponsor dashboards from becoming shadow SORs.
Deeper problem framing
Investigational product custody breaks at clinic handoffs and satchel logistics. Shared logins and paper freezers fail inspections.
Approach
Attributable scans, controlled pharmacy zones, Part 11-aware design, train site staff, unambiguous SOR.
Outcomes and measurement
Reconciliation time, missing-kit rate, inspection retrieval drills.
Governance, risk and what we refuse to claim
Figures from this engagement only. Your payback depends on adoption, integration quality and exception labour, not tag unit cost. Named references under NDA on engagement.
We challenge any supplier who asks you to accept demo-day averages as production truth.
Implementation sequence and change management
Map handoff points clinic-pharmacy-courier. Enforce unique logins. Validate where Part 11 applies. Train site staff with short competency checks. Keep sponsor dashboards read-only to the SOR.
Drill missing-kit reconciliation under time pressure. Score suppliers on attributable trails and e-sign capability, not map polish.
Buyer checklist, supplier challenges and engagement shape
For clinical-trial custody, prioritise attributable Part 11-aware trails over real-time map polish.
Buyer checklist before you sign: (1) written system of record for events; (2) acceptance tests with 95th-percentile performance under real interference; (3) integration owner named in IT/OT; (4) privacy or labour consultation path if people are tagged; (5) cybersecurity zoning sketch; (6) five-year TCO including batteries, spares, recalibration and SLA escalations; (7) exit/export terms so you are not hostage to a cloud tenant; (8) a pilot that can fail without political punishment.
Supplier claims to challenge in this pattern: brochure accuracy without production load; 'compliance included' without artefacts; ROI that assumes perfect adoption in 30 days; references that cannot be called under NDA; install partners who have never worked your vertical's overlays; shared support accounts; and any design that dumps locating onto a flat plant or clinical VLAN.
How TRACIO typically engages: stage-1 architecture and measurement design; independent shortlist and RFP language; pilot acceptance criteria; then optional implementation oversight or programme rescue if a prior pilot stalled. We don't sell hardware, so our advice stays independent. Pages like this one exist so you can prepare the workshop. Your numbers replace every planning band when we model payback.
Risk register themes that recur: mute fatigue on alerts; shadow spreadsheets reappearing beside the platform; battery logistics understaffed; master data too weak to support identity; works-council or IG review starting too late; and success declared on demo day before night-shift reality.
Document baseline windows explicitly: what you measured, for how long, which shifts, and what you excluded. Investment committees and auditors both punish fuzzy before/after stories. If your baseline is weak, spend two to four weeks fixing measurement before ordering anchors or portals. That discipline is cheaper than a stranded deployment and is the difference between a locating programme and a technology souvenir.
Training and communications plan: who explains purpose to operators, how often refreshers run, how contractors are inducted, and how successes are fed back without turning safety systems into league tables. Budget a champion network on each shift. Platforms do not adopt themselves. Where unions or works councils exist, share the purpose statement and retention rules early. Surprise monitoring is how programmes die. Finally, schedule a formal gate review against the written criteria; celebrate a no-go if evidence is weak. Expanding failure is not delivery.
Last updated:
Custody and condition
Independent advisory means the radio is chosen last. After the job, the constraints and the system of record are clear.
Chain-of-custody and excursions
Serial identity and temperature jobs are scoped separately when they differ.
Validation-aware selection
Supplier choice respects audit trail and change control, not slideware.
Into the quality system
Events designed for the records QA will actually defend.
Measurement
Baseline: excursion tickets, custody gaps, and time-to-quarantine on the target lane. Pilot: one lane or depot with identity + condition events vs the QMS/WMS. Steady-state: excursion response time, custody exception rate, and audit trail completeness. GxP claims only within validated scope. Figures are as reported in this engagement.
