Trusted Resource for Clinical Trials, Protocols & Progress
Clinical trials involving biologics, vaccines, cell and gene therapies, or specialized small molecules often demand strict temperature control throughout the product’s lifecycle. Cold chain logistics encompasses the planning, handling, storage, transportation, and monitoring of temperature-sensitive clinical materials, ensuring their stability and efficacy from production to administration.

A temperature excursion occurs when an investigational product is stored or transported at a temperature outside the established range defined by its stability data. Even short-term excursions can impact the quality, potency, or safety of the drug.

Biologicals, including monoclonal antibodies and gene therapies, and vaccines are complex molecules susceptible to degradation. Exposure to inappropriate temperatures, moisture, or light can compromise their safety and efficacy. Regulatory bodies like USFDA and EMA mandate validated packaging that maintains required temperature ranges throughout the cold chain process.

Temperature excursions can jeopardize the safety, efficacy, and stability of IPs. Human errors—such as mishandling shipments, incorrect logger usage, or delayed deviation reporting—are among the most common root causes. Proper training reduces these risks and helps meet USFDA, EMA, and CDSCO requirements.

A cold chain deviation is any unplanned event where a temperature-sensitive IP is exposed to conditions outside its predefined storage range (e.g., 2–8°C or -20°C). Deviations may occur in transit, at clinical sites, depots, or storage facilities.

Temperature excursions during transit can result in product degradation, protocol non-compliance, and costly delays. Regulatory bodies like the USFDA and EMA require proof that IPs remained within acceptable conditions during shipment. Real-time tracking offers immediate insights into shipment conditions, location, and alerts in case of deviation.
