ADC Drug Product Manufacturing

ADC drug product manufacturing converts purified ADC drug substance into a stable, sterile, and appropriately packaged dosage form suitable for clinical or later-stage use. The process requires careful control of formulation conditions, product concentration, sterile processing, filling, and storage to maintain the quality and activity of the conjugated molecule.

Protheragen provides ADC Drug Product Manufacturing support covering formulation preparation, drug product processing, sterile filtration, aseptic filling, and related manufacturing activities. Manufacturing strategies can be adapted to the characteristics of the ADC molecule, formulation requirements, development stage, and intended clinical or manufacturing use.

Overview of ADC Drug Substance Manufacturing

ADC drug product manufacturing requires close coordination between formulation development and manufacturing operations because ADCs may be sensitive to concentration, pH, ionic strength, excipients, temperature, agitation, and other processing conditions. A suitable manufacturing strategy therefore aims to maintain product stability while ensuring consistent drug product quality throughout sterile processing and filling.

The manufacturing workflow typically connects drug substance preparation, formulation, compounding, sterile filtration, aseptic filling, and final drug product handling. Depending on the product and development requirements, liquid or lyophilized presentations may be considered to support appropriate stability and storage conditions.

For ADC programs, manufacturing controls can be integrated with analytical testing to monitor attributes such as protein concentration, purity, aggregation, DAR, free payload, charge heterogeneity, and biological activity throughout drug product manufacturing.

Our Services

ADC drug product manufacturing can be configured according to the formulation, presentation, development stage, and manufacturing objectives. Key activities may include the following.

ADC Drug Product Manufacturing Process

ADC drug product manufacturing integrates formulation preparation, bulk processing, sterile filtration, aseptic filling, and final product handling into a controlled workflow. The specific process can be adapted to the ADC molecule, formulation type, development stage, and manufacturing objectives, with appropriate controls applied throughout each step to maintain product quality and consistency.

ADC Drug Product Quality Attributes

ADC drug substance manufacturing is closely connected with analytical characterization and quality control. Relevant quality attributes can include:

The exact release and in-process testing panel should be established according to the ADC molecule, formulation, manufacturing stage, and applicable quality requirements.
