Understanding Validation – Most Common Types of Validation in the Pharmaceutical Industry

What is process validation

This type of validation is used to confirm that a manufacturing operation consistently produces products that meet defined quality standards. This process collects and evaluates data from the process design stage throughout production. Process validation helps identify potential risks, monitor critical control points, and mitigate any variations that could affect the final product’s quality.

In the ever-changing landscape of compliance regulation, industries keep shifting towards more suitable and improved validation processes. More and more organizations are moving towards continuous process verification (CPV), thus embracing real-time data monitoring to validate their processes in a more efficient way, aligning with FDA’s process validation guidelines.

How to validate a pharmaceutical process

There are four distinct types of process validation for manufacturing processes:

1. Prospective validation: also known as premarket validation. This type of process validation validates a manufacturing process before a commercial product begins or a new process is applied.
2. Concurrent validation: it involves the validation of a manufacturing process that’s already being used in production.
3. Retrospective validation: it takes place when the process hasn’t been validated prospectively. It’s conducted with the use of data and trends analysis to prove that the manufacturing process’s state is where it should be.
4. Revalidation: it’s used when the results of prospective validation show that the manufacturing process is unable to produce consistently.

What is cleaning validation?

Cleaning validation ensures that all equipment is cleaned properly to eliminate contaminants like product residues and cleaning agents, avoiding product contamination. It’s critical to account for worst-case scenarios in cleaning validation, ensuring that even the most difficult-to-clean residues are effectively removed.

This type of validation focuses on testing and verifying equipment cleanliness, keeping the level of cleanliness within acceptable limits, and ensuring the quality of the next manufactured batch or product is not compromised.

Why is cleaning validation important?

If a product has been manufactured under cross-contaminated circumstances, it can compromise not just the product’s quality, but the patient safety. Cleaning validation isn’t just required for this reason: ineffective cleaning processes also lead to batch failure, extended downtime, and non-compliance issues.

What is Analytical Method Validation?

The process of analytical method validation demonstrates that the analytical procedure used for a specific process or test is suitable for its intended use: reliable, accurate, and consistent. Analytical method validation must align with ICH Q2(R1) guidelines, which require a thorough evaluation of accuracy, precision, specificity, and linearity to ensure reliability.

In pharmaceutical manufacturing, method validation confirms that the procedures used to measure a drug’s potency, purity, or stability always produce dependable results.

Key Steps in Method Validation

Method validation includes several critical steps to ensure that the testing methods work:

• Accuracy: Confirms that the method provides results close to the true value.
• Precision: Ensures consistent results when the method is repeated under the same conditions.
• Specificity: Verifies that the method identifies the target substance without interference from other components.
• Linearity: Confirms that results are proportional to the concentration of the substance being tested.
• Robustness: Tests if the method remains reliable under small variations in test conditions.
• Range: Defines the concentration limits within which the method operates effectively.

What is Computer System Validation?

CSV is a process used in biopharma, biotech, and pharmaceutical industries to determine, through a series of tests, if a computerized system is regulated.

Validating a computerized system ensures that its performance is consistent and reproducible, and the results are as safe, secure, and reliable as paper-based records.

Traditional CSV vs Risk-Based Approach

Historically, CSV processes have been time and resources consuming. They can also be quite rigid: each system, independently of its differences, is approached following the same validation processes.

Risk-based CSV approach focuses your efforts where they matter most. This methodology is intertwined with QRM (Quality Risk Management), a systematic process for assessing, controlling, communicating, and reviewing risks. This is how it works:

• Risk assessment: categorize your systems based on their impact on product quality, patient safety, and compliance.
• Criticality analysis: derive more efforts into the systems that involve a higher risk.
• Tailored validation protocols: as mentioned, the validation protocols are made-to-measure for each system and their associated risks.
• Continuous monitoring: this protocol ensures that validated systems remain this way. This step is also tailored: higher-risk systems have continuous monitoring, while low-risk systems are monitored periodically. Continuous compliance through ongoing system assessments is vital, particularly in ensuring the data integrity principles outlined in both FDA and EMA regulations. EU Annex 11 plays a pivotal role in governing the validation of computerized systems, ensuring that they meet stringent criteria for data integrity and security.
