FDA Process Valid On statistical model v Manufacturers have extensive knowledge about critical product and process parameters and quality attributes. Manufacturers strive for continuous improvement. Initial verification, subsequent audit. No manufacturing supplements needed. Process Validation is an enforceable requirement for finished drug products: Lifecycle Stages Description of Activities Stage 1: Process Design Lab, pilot, small scale and commercial scale studies to establish process based on knowledge Stage 2: Process Qualification Facility, utilities and equipment Performance Qualification Confirm commercial process design Stage 3: Stage 1 provides the following: Building and Capturing Process Knowledge and Understanding 2.

Establishing a Strategy for Process Control? The knowledge gained in the design stage will lead to achieving confidence in your process during the next stage of validation. Before commercial distribution begins, a manufacturer is expected to have accumulated enough data and knowledge about the commercial production process to support postapproval distribution. The PPQ is how one demonstrates the knowledge required to support distribution. Recommended for the PPQ protocol: The number of samples should be adequate to provide sufficient statistical confidence of quality both within a batch and between batches.


The confidence level selected can be based on risk analysis as it relates to the particular attribute under examination. Sampling during this stage should be more extensive than is typical during routine production. Some references that may be useful include the following: Many industry standards, books, and guides on these topics are available.

E Standard Practice for Process and Measurement Capability Indices, –

There are many other tools available. You can use appropriate, recognized, standards and methodologies when designing and analyzing your process validation data. However, your process validation sampling plan should be adequate to demonstrate sufficient statistical confidence of quality.

So, your sampling plan, What does the data need to demonstrate prior to distribution?

Can the system consistently make product that meets specifications? Commonly used Statistical Tool: What is you lower bound on your CPK confidence interval? Are all the criteria met to analyze the data using this tool? Unlike capability studies, time is taken into consideration. Control atsm do not exceed CQA specifications.

The asmt is constant over time. Does the system ensure consistent product, even with varying inputs? Are you seeing natural variation or special cause variation?

Do you see acceptable time based variation both within batches and between batches? The sampling plan was adequate? The system is stable?


The system is capable?

Perform activities to continually assure that the process remains in a state of control. Sampling e281-03 Statistics 21 CFR Acceptance criteria for the sampling and testing conducted by the quality control unit shall be adequate to assure that batches of drug products meet each appropriate specification and appropriate statistical quality control criteria as a condition for their approval and release. Valid in-process specifications for such characteristics shall be consistent with drug product final specifications and shall be derived from previous acceptable process average and process variability estimates where possible and determined by the application of suitable statistical procedures where appropriate.

Examination and testing of samples shall assure that the drug product and in-process material conform to specification. asym

Written records required by this part shall be maintained so that data therein can be used for evaluating, at least annually, the quality standards of each e281-03 product to determine the need for changes in drug product specifications or manufacturing or control procedures. Every batch manufactured provides more data. With more data, one can enhance process and product understanding? Process Validation asttm required of drug manufacturers? Confidence is required prior to distribution of product?
