Cold Chain Management Challenges

Competing priorities, changing expectations, cost pressures, sustainability initiatives, and emerging markets – are some of the challenges facing cold chain management professionals every day. Solutions that deliver value in the supply chain and enhance your regulatory reputation are required every day, around the globe. Today, engineers and manufacturers face economic and regulatory pressures, accelerating costs, technology changes, and the need to constantly adapt their business models. The advent of more widely distributed supply chains and other influences demand greater investment in tools, expertise, and, most importantly, human capital.

Investment in these mediums is needed to rise above some of the toughest challenges:

  • Appropriate expertise and techniques to assess, control, and communicate risk as part of an ongoing management review process.
  • A lifecycle approach to process validation including design, qualification, and verification.
  • Better integration of product formulation, controlled environment logistics, and packaging design.
  • Innovative, forward-looking quality controls, corrective and preventive actions (CAPAs) strategies, and root cause analyses for once straightforward, highly complex processes today.
  • The application of technology to achieve greater gains in all areas, including compliance, quality, and safety.

As the pharmaceutical and biologic industries become global, more API (Active Pharmaceutical Ingredient), Drug Substance (DS), and drug products are being manufactured in one region and transported/imported/exported to other regions around the globe. As a result, supply chain safety and validation are becoming much more critical. Third-party logistics (3PL) partners are increasingly involved in product handling, storage, and distribution. This includes contract manufacturers, repackaging companies, wholesalers, distributors, hospitals, mail delivery and distribution companies, retail pharmacies, logistics companies, freight companies, etc. Other areas that should be included are warehouses, intermediate/temporary storage and transportation areas, operation vehicles, transportation cabins, containers, trucks/automobiles/emergency vehicles, rail cars, ships, etc.

All links along the pharmaceutical supply chain must ensure that product handling, storage, transportation, and distribution are performed appropriately for shock and vibration, temperature, relative humidity, light, oxygen, and other relevant environmental conditions.

Adequate control and monitoring for these conditions should be established and validated to assure product identity, strength, purity, efficacy, quality, and safety.

Temperature and Relative Humidity-Controlled Transportation Products

Temperature and relative humidity-controlled transportation products require special temperature, relative humidity handling, and equipment usage during storage, transportation, and distribution. These products may be shipped outside their official storage conditions, onlybased on approved stability data or other scientific/technical justification that product quality will not be affected by product manufacturing until arrival at patients.

The US FDA, EMEA, ICH, and a host of other regulatory agencies have issued guidance documents on principles of process validation. However, most do not address transport issues specifically. The requirement to validate all critical-to-quality processes remains. There are new approaches to answer these questions on how transport networks can be validated.

Cold Chain Transportation

Cold chain transportation can be validated just like any other process. Process validation aims to create a robust process that consistently produces product with minimal variation. The same goal is set for your distribution processes. By applying good validation principles to your distribution processes, you can validate your transport process. This approach requires qualified packaging and equipment (e.g., over-the-road trucks, active refrigeration units, etc.) and a new approach to process definition for your cold chain transportation network.

In the next article of the series, we will discuss where it all begins – integrating your cold chain management system. You’ll learn about the seven components that work together for a compliant cold chain management system.
