Validation : Regulatory Compliance • Validation – a Key requirement of all GMP Guidelines – – – – –

Process Validation Cleaning Validation Analytical Methods Validation Computer systems validation Facility / Equipments Validation / Qualification ( IQ/OQ/PQ )

• Packaging Validation : – to confirm that the resulting product from a specified packaging process consistently conforms to product attributes & requirements.

– A risk-based approach - focusing on processes that have the greatest potential risk to product quality • provides a rational framework for developing an appropriate scope for validation activities. 2

Validation : Packaging Operations • US-FDA and EMEA Regulatory compliance • ‘equipment must be suitable for its intended use’. • need to validate packaging machines / their various component

• Validation process: technically complex, time consuming, costly

• Key Elements : – Qualification of equipments : all relevant sub-systems are thoroughly tested and documented to provide the information that is essential for successful validation. – Validation of a Product Packaging operation – PQ : verification of facility, utilities, equipment performance, components, trained personnel and processes • Evaluation of variance & Assessment of impact on Critical Product Quality attributes

– Cleaning validation : Part of Packaging Validation 3

Validation Qualification or Validation? • Qualification and validation are essentially components of the same concept • The term qualification is normally used for equipment, utilities and systems : A system must be qualified to operate in a validated process

• The term validation is normally used for processes • In this sense, qualification is part of validation, e.g. you qualify an autoclave, whereas you validate a sterilization process

• Qualification should be completed before process validation is performed 4

Validation : Packaging Operations • A validated process: enables consistent packaging of products to meet the product / market requirements - Quality attributes/consumer needs - in a cost effective & an efficient process with minimum down time, rejects and errors. •

Consistency & Cost effectiveness - key business considerations, a validation activity should be seen not as a regulatory requirement but as a business necessity

• Multi-disciplinary effort: equipment engineers, packaging technologists and quality teams must plan and work through a validation program together in order to create a robust operation & ensure consistent Quality packaging 5

Packaging • Packaging : “the art, science and technology of preparing goods for sale in a cost effective manner.”

• Filling, Sealing, Inspection, Labeling, Final Packaging

• In the context of pharmaceuticals, the packaging must: – – – – – –

preserve the product - from degradation or contamination contain the product - to avoid leakage identify the product - providing traceability, security - against tampering and counterfeiting information on use - an ―aide memoir‖ for compliance convenience in use - for medical staff or patient

All this must be ensured for the life of the product and achieved within a complex regulatory environment. 6

Packaging Validation : Pre-requisites • Key areas impacting the robustness of a packaging process - should be considered in validation: – Packaging equipment & Line Layout / Facility space – Packaging materials – SOPs : Equipment Operation, Maintenance, Cleaning – Calibration Program – Operator Training – Master Validation Plan – Packaging Equipment IQ/OQ/PQ & Validation Protocols 7

Validation :Packaging Line Layout • The design and layout of equipment has major impact on the efficiency of the packaging line.

• Line Layout : – Design for a line layout should include the ability to manage quick change-over, perform line clearance between batches of product and clean the line in an easy and controlled manner.

– The majority of problems on packaging lines are related in some way to poor line clearance - important to design these problems out. – Devices will normally be located in critical positions on the line to detect presence or otherwise of the materials. – The layout should provide easy access for operators and the engineers for adjustments and or maintenance 8

Validation : Packaging Line Equipment • Well designed equipment will lend itself to efficient packaging of a consistent standard , ensuring that the machine, as supplied and installed: – – – –

Meets Product Packaging expectations. Performs according to Packaging design intentions Complies with GMP standards Is provided with a record of key features and components as initially installed. – Is provided with information to enable safe, effective and consistent operation and maintenance. – Has it systems tested and verified as being in correct working order, to enable validation to be performed.

Validation : Packaging Line Equipment • Validation strategy 1st step : important to define the topology of the system - defines the scope of the project.

• Detail the packaging line system within the validation protocol • Identify and list the system functionality, the Software and Hardware of the system • Identify the critical measuring devices that need calibration e.g. pressure gauges, thermocouples, hygrometers etc..

• Assess the GMP risk : define if the system has the capability to impact on the Product in of Quality, Strength, Identity or Purity, leading to product withdrawal / recall. 10

Validation : Packaging Lines GMP risk • Incorrect or contaminated pharmaceutical product • Incorrect assembly of the ‗unit of dose‘ carrier (blister, bottle, vial..) • Incorrect packaging component in the final assembly (incorrect carton, missing/incorrect label /leaflet…) • Incorrect or illegible lot or batch identification

Business and operational risk • • • •

Poor packaging quality (cosmetic defects) Excessive machine down time Machine damage or wear Excessive change-over times / Slow speed of operation 11

Packaging Materials • Variety of Packaging Materials – Moisture-impermeable containers (Vials /bottles - glass / plastic, Alu-Alu blisters , Blister strips ( multi layered foils ) – Moisture-permeable containers ( PVC blisters, LD/HDPE containers )

• Multiple suppliers for same packaging item

• An efficient production line needs consistent materials – The storage and handling of components is as vital in this respect as their specification to maintain consistency. – Fiber-based materials, such as leaflets (inserts), cartons and labels can be adversely affected by temp/RH changes. – Supplier / Material qualification, audits, rigorous packaging material specifications Specifications - should include thickness and permeability coefficient 12

Packaging Validation : SOPs • To manage a packaging line, adequate standard operating procedures (SOPs) will be required. • Vital to ensure SOPs provide clear and unambiguous instructions on – how to operate, adjust, and maintain each piece of equipment – detail how a batch is packaged, – explains how each material is received on the line and checked for correctness, quantity, – Details of In Process Control (IPC) tests – Procedure for Line clearance / change-over, including details of cleaning operations to avoid cross-contamination 13

Packaging Validation : Training • The supplier should identify training needs and provide appropriate training. – – – –

Consider the specific packaging methods, Machine operating techniques, hardware/software to be used, Selection / identification of packaging materials Product packaging requirements

• Records of relevant training and experience should be maintained & available as part of the project documentation. • The requirement is for classroom training with notes and a test to be made at the end, in both theory and practice. • Training Module – for retraining / training new operators 14

Validation Master Plan (VMP) Any validation exercise must start with a detailed Validation Master Plan, will include key elements of the validation program. – Company’s validation policy – organizational structure of validation activities – summary of facilities, systems, equipment and processes validated/to be validated. All critical equipment, systems, devices, software must be identified and listed – Defines nature & extent of testing, test procedures – documentation format (e.g. protocol and report) – planning and scheduling – change control process - Any validation activity is only as good as the change control process used 15

Qualification Protocols • A classical approach to validation : prepare protocols for DQ, IQ, OQ and PQ. – test each piece of equipment in the line and to test the interaction between different pieces of equipment /systems. – designed to test all the critical steps, providing a list of tests which are to be performed and the acceptance limits for each test.

• Tests must demonstrate that the system is able to: – do what is expected within the operating range required for the

process. – Test beyond the normal operating range to provide information on the system behaviour, which can be used to finalize operational limits.

16

Validation Protocols • Short description of the process with a summary of the critical processing steps or critical parameters to be monitored during validation. • Additional testing intended to be carried out (e.g. with proposed acceptance criteria and analytical validation as appropriate). • Sampling plan — where, when, how and how many samples are taken ( more sampling than normal IPC ). • Details for recording and evaluation of results.

17

Performance Qualification • PQ, the last stage in validation, should reflect the ‗real‘ production environment, using production materials in a normal daily operation.

• The exercise should extend over a time period sufficient to ensure that shift working patterns and normal lunch breaks etc. are included and to certify that the systems are challenged for stop/start, batch changes etc.

• It is important to document the rationale for a matrix approach in the VMP - what and why it will be done. 18

Validation : Change Control Changes that require revalidation • • • • • • •

Software changes; Controllers Site changes; Operational changes Change of source of material Change in the process Significant equipment change Production area changes system changes

19

PQ - Examples • Blister Packing : – Speed & Temperature settings / range – Different materials – Different suppliers – Different products

– Need to package at extreme temps & evaluate its impact on Quality • Sealing Quality • Pack appearance ( Aesthetics ) • Product Quality ( Stability, purity, assay etc ) 20

PQ - Examples • Ampoule / Vial Filling & Packing : – Filling : – Fill volume variation : fill accuracy – Splashing, spillage, container damage – deoxygenate, if required (assay )

– Seal quality : aesthetics, seal test ( leak test ) – Labeling / information overprinting – Inspection : manual, automatic, bar code reading – Line speed – Product viscosity 22

Common Issues • Packaging process validation is often supplemented by 100% inspection online - firms take the approach that it is the way to go & have inspectors set up offline to sort out / rework unacceptably packaged product. • Cause : Packaging process variables are not adequately identified, studied / not observed to ―nail it‖ through the validation. • Solution : – Validate packaging process by optimizing the packaging process variables and making three runs. – A statistically valid sampling plan implemented & samples tested per the finished product specifications. – Critical variables impacting quality identified & controlled 23

Tips & Hints • Understand thoroughly the packaging system and its critical steps. • Never under estimate the amount of time needed to develop plans - more time you spend in design of the protocols, the less you will waste in resolving issues and investigating failures. • Develop a good sound sampling plan - IPC tests are meaningful and provide useful data on the line performance (samples should reflect the normal operating conditions). • Detect, understand sources & degree of variation, it‘s impact on product attributes and control variations • Finally, any validated system is as good as the associated change control process. – make sure all changes are fully assessed and documented. – the impact of the change on the validation status of the system must be fully assessed before any changes are made. 24

Summary • Industry • Constantly challenged to reduce costs • New markets and new packs add complexity to the operation • An ever changing regulatory environment demands compliance.

• To ensure pack integrity, manage complexity, maximize efficiency and minimize costs; appropriately designed packs, running in validated packaging lines, are a business necessity rather than a regulatory requirement.

• If validation is well planned and documented, then GMP compliance will naturally follow.

Importance of Validation : Cost of Quality Visible costs, e.g., waste, returned / recalled goods ………………………………..

Invisible/Hidden costs, e.g., wrong decisions ( machine, change part ), non-trained workers, Non-standardized process, low yield, maintenance / idle machine time, unsuitable packaging material etc. 27
