GMP-compliant cryostorage: What laboratories and biobanks need to know

When the quality of the technology determines approval

In the pharmaceutical industry and in clinical research, Good Manufacturing Practice (GMP) is more than a set of rules - it is the basis for the confidence of patients, regulatory authorities and society as a whole in the safety of medical products. For facilities that cryopreserve biological samples for therapeutic purposes, this results in comprehensive requirements for every single element of cryostorage.

From the quality of the freezer used to the traceability of stored samples and the documentation of every single temperature deviation - GMP leaves no aspect unconsidered. For many laboratories, the question is not whether, but how they can make their cryogenic infrastructure GMP-compliant.

Consarctic® was founded with the mission to develop cryoproducts that not only meet but exceed these stringent requirements. In this article, we offer a comprehensive guide to GMP-compliant cryopreservation.

The four pillars of GMP in cryogenics

1. Qualified equipment

Every device that is used in a GMP-regulated process must be qualified. For cryogenics, this means

  • Design Qualification (DQ): Has the device been developed for the intended use?
  • Installation Qualification (IQ): Was it installed according to the manufacturer's specifications?
  • Operational Qualification (OQ): Does it work within the specified parameters under real conditions?
  • Performance Qualification (PQ): Does it reliably fulfill its purpose over a longer period of time?

Consarctic® supplies the complete DQ, IQ and OQ documentation for all products - from controlled rate freezers to nitrogen tanks. Our certified technicians carry out on-site qualification and train your staff in correct operation.

2. Validated processes

It is not enough to have qualified equipment - the processes themselves must be validated. This includes:

  • Freezing protocols: Each freezing curve must be validated and documented as a standard operating procedure (SOP).
  • Storage conditions: The temperature stability in the cryogenic tank must be verified over the entire storage period (temperature mapping).
  • Transport validation: If samples are transported in a dry shipper, the cold chain must be validated under worst-case conditions.

3. Complete documentation

The GMP maxim is: What is not documented has not taken place. This results in the following for cryopreservation:

  • Batch Records: Each freezing process is recorded with all parameters (temperature curve, CPA used, batch designation).
  • Audit Trail: Electronic systems must guarantee a tamper-proof record of all changes and accesses.
  • Deviation management: Any deviation from a validated process - e.g. a temperature alarm - must be documented, evaluated and corrected if necessary.

4. Trained staff

All employees involved in cryopreservation must be demonstrably trained and the training must be regularly refreshed. Consarctic® offers comprehensive training programs for laboratory technicians and quality officers as part of its turnkey solutions.

Temperature mapping: proof of homogeneity

Temperature mapping is a particularly critical aspect of GMP compliance. This involves verifying that the temperature inside a cryogenic container meets the specified criteria at all storage positions.

The eccentric opening of the Consarctic® BSD+ tanks helps to achieve a particularly homogeneous temperature distribution, as the heat input through the opening is minimized. This makes qualification considerably easier.

Software validation

The software used in Consarctic® systems for control and monitoring fulfills the requirements for computerized systems according to Annex 11 of the EU GMP guidelines. These include:

  • User management: Individual access rights and password protection.
  • Data integrity: ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate).
  • Backup and recovery: Regular data backup and validated recovery procedures.

GMP as an investment in the future

Implementing a GMP-compliant cryogenic storage system requires careful planning and an investment in quality. But this investment pays off: It protects against regulatory complaints, product losses and - in the field of personalized medicine - against compromising patient safety.
