Dry Ice in Clinical Trials. What Biotech, CRO, and Pharma Companies should be aware of? 

Clinical trials are the backbone of medical advancement, providing the necessary data to bring new treatments to market. For biotech, CRO, and pharmaceutical companies, ensuring the integrity of biological samples during transportation is critical. One vital component in this process is the use of dry ice. This article delves into the importance of dry ice in clinical trials, highlighting its benefits, usage, and best practices. 

What is dry ice and why is it so important in clinical research? 

Dry ice, the solid form of carbon dioxide (CO₂ ice), is essential in clinical trials for several reasons: 

1. Temperature Control: Dry ice maintains its solid state at -78.5°C and sublimates at -78°C or higher. These features make it ideal for maintaining the low temperatures required for the preservation of biological samples such as blood, tissue, and DNA 

2. Non-Toxic and Non-Water-Based: Unlike water ice, this ice does not melt into a liquid but rather turns directly into gas, preventing any risk of contamination or moisture damage to the samples. 

3. Environmentally Friendly: There is no need to purchase additional, complicated cooling machines for using CO₂ ice, and no electricity is required for the cooling process. It is a natural cooling method as it consists only of carbon dioxide. 

4. Efficiency: Its ability to maintain low temperatures for extended periods makes it a reliable choice for long-distance or prolonged shipping durations. Importantly, dry ice is non-flammable, which is particularly crucial for shipping. 

The role of dry ice in sample transportation 

In clinical trials, the integrity of biological samples is paramount. Dry ice plays a crucial role in: 

1. Preservation of Sample Quality: By keeping samples at ultra-low temperatures, ice ensures that biological activity is halted, thus preserving the samples’ integrity until they reach the laboratory for analysis. 

2. Regulatory Compliance: Many regulatory bodies, including the FDA and EMA, have stringent guidelines for sample transportation. Using dry ice helps meet these requirements by maintaining consistent low temperatures. 

Best practices for using dry ice in clinical trials 

 To maximize the benefits of dry ice in clinical trials, consider the following best practices: 

1. Proper Packaging: Use insulated containers designed for CO₂ ice. Ensure that the packaging is robust and compliant with international shipping regulations. 

2. Adequate Ventilation: This type of ice sublimates into CO₂ gas, which needs to escape. Ensure the packaging allows for this gas release to prevent pressure build-up. 

3. Labeling and Documentation: Clearly label packages containing dry ice and include appropriate documentation for handling and emergency procedures.  

Going into more specific requirements, in accordance with IATA regulations, shipments with dry ice must be labelled (CO₂ ice, UN 1845, Class 9 Miscellaneous label). Additionally, the net weight must be indicated on the external packaging. 

4. Monitoring: Use temperature monitoring devices to track the conditions throughout the transportation process, ensuring that the samples remain within the required temperature range.
