Importance of process safety in fluid management of ADCs
When handling ADCs, there are several challenges to overcome, including process safety in their fluid management. Read about these difficulties and how to overcome them in this article!

Antibody drug conjugates (ADCs) are a promising alternative for cancer therapy. Due to the targeting quality of the monoclonal antibody (mAb) in combination with a highly toxic payload drug, it becomes easier to target cancer cells without potential harm to healthy cells which is a big advantage to common chemotherapeutic methods. Because of the potential of this formulation, process development has become a growing field of interest for the pharma industry.
However, the high toxicity of the product also bears a lot of challenges which need to be overcome. Scale-up and industrial production of ADCs face complications due to the high safety measures which need to be taken to guarantee product efficacy and a protected working environment for staff and manufacturers.
In this article we seek out to give you an overview of the different challenges during ADC manufacturing while also introducing solutions which help to ensure aseptic production methods through single-use-technologies and end-to-end systems.
Since ADCs are highly hazardous substances, GMPs help protect employees and the environment from coming into contact with it. Therefore, quality control has to start right from modifying and purifying mAbs to combination with an effective cytotoxin through a stable linker, while maintaining the right drug-antibody-ratio (DAR).
Aseptic manufacturing plays an important part in the quality control of ADCs and helps to ensure that the biotherapeutic is not contaminated.
To make sure that no alterations occur during the manufacturing chain, controlled freezing and thawing of ADCs is important for an efficient and successful production without product loss.
These special conditions make ADC manufacturing a time consuming, cost intensive and laborious process. However, new technologies and developments in the production process help for optimization, streamline each step and reduce the risk of product loss.
As an example, fully automated and closed end-to-end processes based on single-use solutions fulfill cGMP requirements and make flexible, scalable, efficient manufacturing possible.
As mentioned before, quality control is one of the most important components of the manufacturing process as ADCs can be prone to contamination and product alterations are a high potential health risk for cancer patients. Therefore, every part of the production process from mAb production to drug substance manufacturing and conjugation has to be monitored at all times before the ADC enters a chromatography system and has to go through purification filtration.
The importance of controlled freezing in the production of ADCs has already been stated above. To answer the question what exactly is meant by controlled freezing, it is necessary to dive a bit deeper in the technique behind it.
In contrast to commonly used freezing mechanisms, controlled freezing becomes possible through plate-freezing technology. Two plates distribute temperature evenly on both sides of a container which reduces the risk of drug denaturation, cryoconcentration and vacuums within the soluble which can alter the ADCs efficacy.
Through using single-use containers it not only becomes easier to safely freeze substances, but they also allow for controlled thawing at the optimal rate for each product. Further, storage is made easier, more efficient, and at higher storage density.
Discover how innovative technologies allow for controlled-rate freezing and thawing of bulk drug substances, and how these solutions can improve overall product quality and safety.
Due to the high risk for staff and patients attached to highly hazardous cytotoxins, ADC production has to follow cGMP standards as issued by the FDA at all times. Aseptic manufacturing plays an important part in the quality control of ADCs and helps to ensure that the biotherapeutic is not contaminated.
These special conditions make ADC manufacturing a time consuming, cost intensive and laborious process. However, new technologies and developments in the production process help for optimization, streamline each step and reduce the risk of product loss. As an example, fully automated and closed end-to-end processes based on single-use solutions fulfill cGMP requirements and make flexible, scalable, efficient manufacturing possible.
In addition to health and safety concerns and quality controls, of course costs are an issue to consider. The field of ADC manufacturing is constantly growing due to its benefits compared to common chemotherapies.
However, cost, time and labor-intensive processes are obstacles in ADC manufacturing. Nevertheless, single-use technologies are about to change these conditions. They are a way to combine all of the aforementioned regards by streamlining the process through fully automated aseptic filling, controlled freezing and thawing methods and closed systems to ensure the required purity of the drug.
For this reason most of the contract manufacturing organizations (CMOs) and contract development and manufacturing organization (CDMOs) operating in different aspects of ADC development or ADC processing like antibody manufacturing or synthesis of biologics rely on single-use technologies because they are the most cost and time efficient way to ensure the safe use of the product.
Single-use technology and equipment was designed to make every step of ADC manufacturing and the management of hazardous fluids more efficient. End-to-end systems support CMOs and developers in their mission to a successful production of a safe-to-use product.
Single Use Support supports manufacturers and contract manufacturers in ADC production with its automated end-to-end solutions based on single-use technology to overcome the manufacturing challenges.
Through single-use technology it is possible to cover the different steps from primary packaging in a protected single-use container to scalable filling without product loss or contamination and controlled freezing. Storage and transport while maintaining the right temperature levels in closed systems guarantees product quality to ensure the safe use of the product after thawing it at a controlled rate. As all of these steps are performed in a closed system, pollution risks are minimized.
