Module 4 | Slide 1 of 28 January 2006

Qualification and Validation

Basic Principles of GMP

Section 4



Objectives

To review basic aspects of qualification and validation

To understand the scope of qualification and validation

Introduction to documentation associated with validation

(See also Supplementary Training Module on Validation)



Definitions

Validation

Action of proving, in accordance with the principles of GMP, that any procedure, process, equipment, material, activity or system actually leads to the expected results

Qualification

Action of proving that any premises, systems and items of equipment work correctly and actually lead to the expected results

(Validation usually incorporates the concept of qualification) Glossary



Principle

Essential part of GMP

Manufacturer to identify what qualification and validation work is required

Prove that critical aspects of work are controlled

Key elements of qualification and validation defined and documented

4.1, 4.2, 4.8



Scope

Documented evidence to prove that, e.g.

Premises

Supporting utilities

Equipment

have been designed in accordance with GMP

Also referred to as Design Qualification (DQ) where appropriate

4.3(a)



Scope

Documented evidence to prove that, e.g. Premises Supporting utilities

Equipment

have been built and installed in accordance with their design specifications

Also referred to as Installation Qualification (IQ)

4.3(b)



Scope

Documented evidence to prove that, e.g. Supporting utilities

Equipment

operate in accordance with their design specifications

Also referred to as Operational Qualification (OQ)

4.3(c)



Scope

Documented evidence to prove that, e.g. Supporting utilities

Equipment

perform consistently in accordance with their design specifications – see also next slide on PV

Also referred to as Performance Qualification (OQ)

4.3(d)



Scope

Documented evidence to prove that: A specific process will consistently produce a product

meeting its predetermined specifications and quality attributes

Also referred to as Process Validation (PV)

4.3(d)



Scope

Qualification and validation:

Applicable to any aspect of operation which may affect the quality of the product Directly or indirectly

Includes premises, facilities (utilities), equipment, processes

Includes significant changes

4.4



Principle

Qualification and validation should be done in accordance with an ongoing programme Initial qualification and validation Annual review

Maintain continued validation status

Policy described in relevant documentation, e.g. quality manual, or Validation Master Plan

4.5, 4.6



Types of Documentation

Validation Master Plan (VMP)

Validation protocols

Validation reports

Standard Operating Procedures (SOPs)



Documentation

Clearly defines responsibility of performing validation

Conducted in accordance with predefined, approved validation protocols

Recorded results and conclusions presented in written validation reports – prepared and stored

Processes and procedures should be established on the basis of these results

4.7 – 4.10



Importance:

Premises, utilities, equipment and processes

Critical importance and particular attention paid to validation of: Analytical test methods Automated systems Cleaning procedures

4.11


Basic Principles of GMPBasic Principles of GMP

What are the qualification and validation requirements here for this piece of equipment, as well as the step in production?


Annex 6


WHO References

Good manufacturing practices (GMP): guidelines on the validation of manufacturing processes

Validation of analytical procedures used in the examination of pharmaceutical materials


Qualification and ValidationExample of priorities for process validation

Type of process Requirement

New Every new process before approval for routine Existing:

Sterile products All processes affecting the sterility, and manufacturing environment including sterilization stage

Non-sterile Low dose tablets and capsules: mixing and granulation; content uniformity (and other parameters)

Other tablets and capsules: uniformity of mass

(and other parameters)


Qualification and Validation The Validation Master Plan may contain elements (and policy) such

as: Approval page and table of contents Introduction and objectives Facility and process description Personnel, planning and scheduling Responsibilities of validation team members Process control aspects Equipment, apparatus, processes and systems qualified,

validated – and to be qualified or validated Acceptance criteria Documentation, e.g.validation protocols and reports SOPs Training requirements and other elements…



A qualification or validation protocol may contain:

Objectives of the validation and qualification study Site of the study Responsible personnel Description of the equipment SOPs Standards Criteria for the relevant products and processes

(See WHO formats (handouts) as part of training material)



A qualification or validation report should reflect the elements of the protocol, and may contain elements such as:

Title Objective of the study Reference to the protocol Details of materials, equipment, instruments, personnel Programmes and cycles used Details of procedure and test methods

… etc.



Group Session 1: Option 1

From your experience of factory inspections, what progress has been made in introducing validation in your country?

What are the major obstacles and how can they be overcome?



Group Session 1: Option 2

List some documents related to validation, that you expect to find at a manufacturing site

Identify aspects in each document that you would evaluate or assess

What problems do you anticipate the company faced when it prepared these documents?



Possible Issues

Lack of time

Lack of personnel

Lack of experience and knowledge

Changes to the process

Prospective versus retrospective validation

Lack of documentation infrastructure

Lack of implementation of validation

Poorly designed documents



Group Session 2

List the aspects that you will evaluate when assessing the validation for the project that your group has been given

Identify the critical parameters that should have been evaluated by the manufacturer

List the tests to be carried out and comment on the acceptance criteria to be set



Possible situation – I

Refurbishment of a liquids department, producing a single product on an established site with an existing purified water system

Ventilation system Equipment and process Training



Possible situation – II

New product introduced into an existing tablet manufacturing site, with 20 products already being produced

Process Cleaning

Training



Possible situation – III

A new liquids manufacturing building on an existing site which will produce 2 products

Ventilation

Equipment and process

Cleaning

Training



Possible situation – IV

An existing sterile suite producing 5 products that are terminally sterilized

Sterilizers Ventilation and other environmental aspects Equipment and process Cleaning Training
