    Study Notes

    Process Validation Overview

    • Process validation is a step-by-step procedure to ensure consistent quality product production.
    • It is performed by a validation team, led by the quality assurance head, within pharmaceutical manufacturing.
    • Validation is crucial before releasing new products, applying changes to existing products, and for periodic process verification.
    • A protocol outlines the validation process, including monitored parameters, samples, and acceptable results.

    Process Validation Stages

    • Stage 1: Process Design: The manufacturing process is defined to reproduce the desired product. Validation teams need a clear understanding of the process. This involves product development activities, production equipment limitations, and risk analysis tools.

    • Stage 2: Process Qualification: The process design is evaluated for its effectiveness in quality production. This includes designing the manufacturing facility according to current good manufacturing practice (CGMP) requirements. This also includes qualifying utilities and equipment to ensure compliance with design specifications. Finally, process performance qualification is documented via a report.

    • Stage 3: Continuous Process Verification: Systems are set up to maintain quality throughout routine production. This frequently uses statistical process control (SPC), continuous monitoring of process parameters, and scheduled maintenance of equipment.

    Types of Process Validation

    • Type 1: Prospective Validation: Used when a new formula or facility is introduced. Also known as premarket validation.

    • Type 2: Retrospective Validation: Used when a manufacturing process hasn't had documented validation.

    • Type 3: Concurrent Validation: Performed throughout regular production to ensure the process maintains quality.

    • Type 4: Revalidation: Used mainly for medical devices, more often than drug products.

    Process Validation Considerations

    • Pilot Scale and Scale-up: Pilot scale batches are used where appropriate, followed by risk assessments to identify critical process quality attributes.
    • Commercial Scale Batches: Commercial-scale batches are also part of qualification which involves in-line, online, and at-line monitoring.
    • Periodic Review and Testing: Periodic reviews of trends, sampling, and testing, are included in continued process verification.

    Quality by Design (QbD)

    • QbD is an approach used by pharmaceutical companies to guarantee the quality of their products.
    • It ensures product safety, efficacy, and high quality for consumer use.
    • QbD improves the performance and quality of manufacturing processes.

    QbD Development Process

    • Target Product Profile (TPP): Defines the product's intended use, safety measures, and efficacy.
    • Target Products and Process Parameters: Includes details about the drug substance, process, and potential excipients.
    • Critical Attributes and Process Parameters: Identify critical parameters for the manufacturing process.
    • Control Strategy: Develops methods to control the process, such as the design of experiments (DOE) and risk assessments.

    Elements of QbD

    • Quality Target Product Profile (QTPP): Identifies critical quality attributes (CQAs).
    • Product Design: Understanding and identifying critical material attributes (CMAs).
    • Process Design: Understanding and identifying critical process parameters (CPPs) and how principles of scaling link both.
    • Control Strategy: Details for drug substances, excipients, and drug products.
    • Process Capability: Measuring and ensuring the process satisfies expectations.
    • Continuous Improvement: Ongoing process enhancement.

    Advantages of QbD

    • Continuous improvement in manufacturing and quality.
    • Supporting change.
    • Prevention of failure.
