Definitions and Objectives of Process Validation

United States Food and Drug Administration (USFDA): The collection and evaluation of data, from the process design stage through commercial production, which establishes scientific evidence that a process is capable of consistently delivering quality product.
- This includes various stages such as design, qualification, and validation of processes, taking into account risk management and continuous improvement.
World Health Organization (WHO): Documented evidence which provides a high degree of assurance that a specific process will consistently result in a product that meets predetermined specifications and quality characteristics.
- It emphasizes the importance of documentation at every step of the process to enable transparency and traceability.
European Medicines Agency (EMA): The documented evidence that the process, operated within established parameters, can perform effectively and reproducibly to produce a medicinal product meeting its predetermined specifications and quality attributes.
- It involves specific parameters, controls, and methodologies that are thoroughly established during the validation phase to ensure compliance with regulatory requirements.

To provide the highest assurance that all production batches (unit doses) will be consistently efficacious as the clinical batch(es).
- This includes rigorous testing and validation processes that reflect the conditions under which the product will be manufactured.
To reduce risk to safety via the highest assurance of acceptable and consistent quality of the product and its components.
- This involves comprehensive risk assessments and the implementation of controls to ensure that any potential risks are identified, monitored, and mitigated throughout the manufacturing process.
