Why do process validation

Challenges in pharmaceutical process validation methods have emerged due to the ever-developing product market and new treatments for patients. Pharmaceutical professionals encounter breakthrough therapy products that require reliable processes and manufacturing, for substantial production.

In validating production processes and data, pharmaceutical leaders can remain competitive with training of manufacturing and delivering life-saving treatments. Industry professionals will greatly benefit from the thoroughly reviewed guidance and exceptional insights from leaders in regulation and academics, included in the good practice guide.

Process Validation. The process outcomes can't or aren't verified, e. The process outcome's deficits would only be apparent when the product is used or after the service has been rendered. These validation activities must comprise: All activities which have been carried out must be recorded, including date and signature.

Procedures, with which process parameters are surveilled, must be established. Only qualified personnel may validate a process. Methods and data used for controlling and monitoring processes, the date of execution, persons carrying out the validation, as well as relevant equipment must be documented. In case of changes, the manufacturer must assess whether re-validation is necessary and must carry it out if needed. Tips for Validating a Process a Only validate relevant parameters Usually, products have several characteristics manufacturers must ensure.

A very simplified example: A syringe must be sterile and of a certain length. At this stage, the basis for calibration, maintenance, and cleaning is provided. It is advised to have a look at the manual OQ: During this most extensive testing, it should be checked whether the device operates according to specifications, especially at specification limits, to know what might happen in the worst case.

PQ, then, is only the proof that the process runs under normal conditions. This test addresses, inter alia, measurement accuracy incl. It is also about long-term stability. In the pharmaceutical world, at least 3 batches are tested. A P-Diagram shows influencing factors such as environmental conditions, work steps, process parameters, and material properties. Here, sampling plans come into play. Back To Top. Customer Stories Watch our customers share their successes.

Process Verification vs. Identifying Processes That Require Validation Other than four processes identified in the preamble of the QSR sterilization, injection molding, aseptic processing and welding , the FDA does not provide guidelines for specific processes that require validation.

A decision tree provided in the GHTF guidelines identifies two fundamental questions device manufacturers should first ask to determine if process validation is required: 5 Is the process output verifiable?

Is verification sufficient and cost effective? In a presentation at the 4th European GMP Conference shortly after the guidance was published, McNally noted that taking a life cycle approach should lead manufacturers to address three key questions when engaging in process validation activities: 7 Do I have confidence in my manufacturing process?

Or, more specifically, what scientific evidence assures me that my process is capable of consistently delivering quality product? How do I demonstrate that my process works as intended? How do I know my process remains in control? Focus your validation approach on risk.

Figure 2. The calculated risk priority numbers RPNs from the actual process validation failure modes effects analysis. For unit operations with RPNs below the threshold, a secondary evaluation was performed.

From Table 3, the buffer preparation and UF installation underwent the secondary evaluation. The secondary evaluation may include whether there are procedural requirements, regulatory commitments, industry expectations, or other requirements that would necessitate the adjustment of the actual protocol.

Of the two unit operations listed, the team agreed that the buffer preparation unit operation should be included as part of process validation. Buffer preparation operations were added to the scope of process validation activities based on past regulatory experiences.

No such experiences necessitated the inclusion of UF membrane installation. Note that UF membrane installation or other processes with RPN values below 30 that were not included as part of process validation are controlled through manufacturing and standard operating procedures. This approach ensures that all operations are appropriately controlled, and those operations with the greatest potential risk to product quality are controlled and validated.

At this point, the risk assessment phase ends. The risk management process would continue through the steps of risk control, risk review, and communication.

This implies that over the course of the product's lifecycle, the risk assessment is reviewed. This review includes adjustments to regulatory requirements or to additional information related to the new process.

This case study represents a risk-based approach to evaluating the scope of process validation activities. Through the use of a process FMEA, an objective assessment of the potential uncertainties and their effect on product quality were evaluated and organized to make the most optimal decisions. The use of a risk-based approach also provided a consistent method for decision making which was easily aligned with business goals such as resource allocation and ensuring patient safety.

Ultimately, applying such a risk-based approach to process validation should reduce the number of surprises or minimize their impact through the consistent use of the tools, proper communication and periodic review. Finally, the risk assessment phase does not replace the role or importance of the decision-maker. The output of the risk assessment should only support and objectively outline the tradeoffs and the uncertainties relative to the meeting the goals of the company or the functional area.
