Purpose
The purpose of this SOP is to establish standardized, regulatory-compliant
Scope
This SOP applies to sponsors, investigators, CROs, site staff, laboratories, and vendors involved in the storage, handling, shipment, and monitoring of temperature-sensitive samples and investigational products. It covers refrigerated (2–8°C), frozen (−20°C, −80°C), and cryogenic storage (liquid nitrogen).
Responsibilities
- Sponsor: Provides requirements for cold chain management, qualifies vendors, and ensures compliance.
- Investigator: Ensures site-level cold chain compliance and documentation.
- Clinical Staff: Monitors, documents, and reports excursions.
- Laboratory Staff: Ensures proper storage and timely processing of samples.
- Courier: Maintains validated cold chain transport and documents chain of custody.
- QA: Audits cold chain documentation and verifies compliance.
Accountability
The Sponsor is accountable for global compliance with cold chain requirements. Investigators are accountable for maintaining cold chain integrity at site. QA ensures oversight, auditing, and inspection readiness.
Procedure
1. Storage Conditions
1.1 Store samples and IPs at specified conditions per protocol.
1.2 Use validated refrigerators, freezers, and cryogenic storage units.
1.3 Maintain temperature mapping and calibration certificates.
2. Temperature Monitoring
2.1 Equip all cold chain units with calibrated temperature probes.
2.2 Implement continuous monitoring with alarms for out-of-range conditions.
2.3 Record temperatures twice daily in Cold Chain Temperature Log (Annexure-1).
3. Excursion Management
3.1 Document excursions in Temperature Excursion Log (Annexure-2).
3.2 Immediately notify Sponsor and QA for assessment.
3.3 Quarantine affected samples/IP until disposition is determined.
4. Shipment
4.1 Use validated thermal shippers with dry ice or gel packs.
4.2 Include temperature monitoring devices in shipments.
4.3 Maintain Chain of Custody Log (Annexure-3).
5. Equipment Qualification
5.1 Perform installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) of cold chain equipment.
5.2 Retain qualification records in Equipment Qualification Log (Annexure-4).
6. Courier/Vendor Oversight
6.1 Only qualified vendors with documented validation may transport samples/IP.
6.2 QA to review courier temperature logs and deviation reports.
7. Documentation
7.1 Maintain Cold Chain File with all logs, deviations, and corrective actions.
7.2 Ensure records are inspection-ready at all times.
