Paradigm 3: Process Validation

Process validation is an essential paradigm in biotech quality assurance. It involves establishing documented evidence that a process consistently produces a product that meets predetermined specifications and quality attributes. Process validation helps ensure that biotech companies can consistently manufacture products that are safe, effective, and of high quality.

A. Prospective process validation

Prospective process validation is performed before commercial production begins. It involves establishing process parameters and performance criteria based on scientific and technical rationale. By conducting thorough testing and analysis, biotech companies can determine optimal process conditions that will consistently produce high-quality products.

During prospective process validation, critical process parameters and their operating ranges are identified. These parameters can include temperature, pH, agitation speed, and sterilization conditions, depending on the specific biotech process. The process is then tested under various conditions to analyze its performance and determine the optimal parameter ranges.

Once the process parameters and performance criteria have been established, robust documentation and standard operating procedures are developed. These documents outline the validated process steps, including critical control points, in detail. They serve as a reference for operators and provide a basis for regulatory compliance.

B. Concurrent process validation

Concurrent process validation is carried out during commercial production. It involves ongoing monitoring and analysis of process parameters and performance to ensure the continued production of high-quality products. Concurrent process validation provides real-time data and feedback on the performance of the manufacturing process.

During concurrent process validation, regular sampling and testing are performed to verify that the process is operating within the established parameters. Process data is continuously collected and analyzed to identify any deviations or trends that may affect product quality. If necessary, corrective actions are taken to bring the process back within specification.

Concurrent process validation includes routine QC (Quality Control) testing to assess the quality attributes of the final product. This involves testing for product potency, purity, impurity levels, and other relevant quality parameters. The results of these tests are compared to the predetermined specifications to ensure that the product meets the required quality standards.

C. Retrospective process validation

Retrospective process validation involves analyzing historical data to establish the validity of a process that has been in commercial production. It is particularly useful for biotech products that have a long history of successful manufacturing but may not have gone through formal prospective or concurrent process validation.

During retrospective process validation, biotech companies review historical production and quality data to evaluate the process performance and identify any trends or areas that may require improvement. If the historical data consistently demonstrates that the process has consistently produced high-quality products, it can be considered retrospectively validated.

Retrospective process validation involves a thorough review of batch records, equipment maintenance records, and quality control data. This helps identify any deviations, non-conformances, or trends that may have occurred during the manufacturing process. By analyzing this data, biotech companies can assess the robustness and reliability of their processes.

It is important to note that retrospective process validation does not replace the need for prospective or concurrent process validation. However, it can provide valuable insights and support the validation of existing processes that have a proven track record of producing high-quality products.
