Basic Principles of GMP Qualification and Validation Section 4 Module 4 | Slide 1 of 31 2012

Qualification and Validation Objectives l To review basic aspects of qualification and validation l To understand the scope of qualification and validation l Introduction to documentation associated with validation (See also Supplementary Training Module on Validation) Module 4 | Slide 2 of 31 2012

Qualification and Validation Definitions Glossary Validation l 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 l 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) Module 4 | Slide 3 of 31 2012

Qualification and Validation Principle l Qualification and Validation: Essential part of GMP l Manufacturer has to identify what qualification and validation work is required. 4. 1, 4. 2, 4. 8 l Provides proof that critical aspects of work are controlled and provide documented evidence l Key elements of qualification and validation defined and documented: Policy and approach: VMP Module 4 | Slide 4 of 31 2012

Qualification and Validation Scope 4. 3(a) l Documented evidence to prove that, e. g. ä Premises ä Supporting utilities ä Equipment have been designed in accordance with GMP l Also referred to as Design Qualification (DQ) where appropriate Module 4 | Slide 5 of 31 2012

Qualification and Validation Scope l Documented evidence to prove that, e. g. ä Premises ä Supporting utilities ä Equipment have been built and installed in accordance with their design specifications 4. 3(b) l Also referred to as Installation Qualification (IQ) Module 4 | Slide 6 of 31 2012

Qualification and Validation Scope l Documented evidence to prove that, e. g. ä Supporting utilities ä Equipment operate in accordance with their design specifications l Also referred to as Operational Qualification (OQ) 4. 3(c) Module 4 | Slide 7 of 31 2012

Qualification and Validation Scope l Documented evidence to prove that, e. g. ä Supporting utilities ä Equipment perform consistently in accordance with their design specifications – see also next slide on PV l Also referred to as Performance Qualification (PQ) 4. 3(d) Module 4 | Slide 8 of 31 2012

Qualification and Validation Scope l Documented evidence to prove that: ä A specific process will consistently produce a product meeting its predetermined specifications and quality attributes l Also referred to as Process Validation (PV) 4. 3(d) Module 4 | Slide 9 of 31 2012

Qualification and Validation Scope Qualification and validation: l Applicable to any aspect of operation which may affect the quality of the product ä Directly or indirectly l Cover e. g. premises, facilities (utilities), equipment, processes 4. 4 l In case of significant changes – consider the need for requalification or re-validation Module 4 | Slide 10 of 31 2012

Qualification and Validation Principle l Qualification and validation should be done in accordance with an ongoing programme ä Initial qualification and validation ä Annual review (determine the need for revalidation) 4. 5, 4. 6 l Ensure continued validation status is maintained l Policy described in relevant documentation, e. g. quality manual, or Validation Master Plan Module 4 | Slide 11 of 31 2012

Qualification and Validation Types of Documentation l Validation Master Plan (VMP) l Validation protocols l Validation reports l Standard Operating Procedures (SOPs) Module 4 | Slide 12 of 31 2012

Qualification and Validation Documentation l Clearly defines responsibility of performing validation l Conducted in accordance with predefined, approved validation protocols l Recorded results and conclusions presented in written validation reports – prepared and stored l Processes and procedures should be established on the basis of these results 4. 7 – 4. 10 Module 4 | Slide 13 of 31 2012

Qualification and Validation Importance: l Premises, utilities, equipment and processes l Critical importance and particular attention paid to validation of: äAnalytical test methods äAutomated systems äCleaning procedures 4. 11 Module 4 | Slide 14 of 31 2012

Basic Principles of GMP 1. List qualification requirements for this piece of equipment. 2. Discuss aspects to be considered in validation during this processing stage. Module 4 | Slide 15 of 31 2012

Qualification and Validation l The Validation Master Plan may contain elements (and policy) such as: ä Approval page and table of contents ä Introduction and objectives ä Facility and process description ä Personnel, planning and scheduling ä Responsibilities of validation team members ä Process control aspects ä Equipment, apparatus, processes and systems qualified, validated – and to be qualified or validated ä Acceptance criteria ä Documentation, e. g. validation protocols and reports ä SOPs ä Training requirements and other elements… Module 4 | Slide 16 of 31 2012

Qualification and Validation l A qualification or validation protocol may contain: ä ä ä ä 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) Module 4 | Slide 17 of 31 2012

Qualification and Validation l A qualification or validation report should reflect the elements of the protocol, and may contain elements such as: ä Title ä Objective of the study ä Reference to the protocol ä Details of materials, equipment, instruments, personnel ä Programmes and cycles used ä Details of procedure and test methods … etc. Module 4 | Slide 18 of 31 2012

Qualification and Validation l New approaches recommend that manufacturers should perform a risk assessment as part of their approach to validation l Risk assessment can be useful in: – Identifying the need for qualification, or the extent and or scope of qualification (e. g. utilities and equipment) – areas of focus in process validation – Cleaning validation Module 4 | Slide 19 of 31 2012

Qualification and Validation l There is currently a move to change the approach to qualification and validation. The principles remain however the same. l US and EU guidance now focus on “Process qualification” which covers the complete lifecycle of a products with additional focus on product design l Three Phases are identified that cover “process design, process qualification” and “continued process verification” Module 4 | Slide 20 of 31 2012

Qualification and Validation Phase I Process design Process qualification Continued Process verification Phase III Module 4 | Slide 21 of 31 2012 Phase II

Qualification and Validation WHO References Supplementary guidelines on good manufacturing practices: validation … including details about Module 4 ä ä ä ä Validation of heating, ventilation and air-conditioning systems Validation of water systems for pharmaceutical use Cleaning validation Analytical method validation Validation of computerized systems Qualification of systems and equipment Annex 4 Non-sterile process validation | Slide 22 of 31 2012

Qualification and Validation Example of priorities for process validation Type of process Requirement l New l Existing: Every new process before approval for routine ä Sterile products All processes affecting the sterility, and manufacturing environment including sterilization stage ä 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) Module 4 | Slide 23 of 31 2012
