- 2. A definition Where did validation come from ? Why do it ? What are the benefits ? How far do we have to go ? 2
- 3. “ Establishing the documented evidence which provides a high degree of assurance that a specific process will consistently produce a product of predetermined specifications and quality attributes.” (FDA Guidelines 1987) 3
- 4. “Process validation is defined as the collection & evaluation of data, from the process design stage through commercial production, which establishes scientific evidence that process is capable of consistently delivering quality product.” (FDA Guidelines, 2011) 4
- 5. “Action of proving, in accordance with the principles of Good Manufacturing Practice (GMP), that any procedure, process, equipment, material, activity or system actually leads to expected results.” (EU GMP 1997) 5
- 6. Began in 1970’s Originally sterilized based. Now evolved into all Product, Process and Facility matters. 6
- 7. Assures Quality Regulatory Requirement Reduces Cost It’s the LAW ! 7
- 8. Validation can reduce costs by reducing, Rejects Reworks Reliance on In-process controls Down time 8
- 9. Reliance on product testing Loss of confidence Possibility of adulterated products Inspection : Observations / 483’s 9
- 10. User Requirement Specification (URS) Design Qualification Impact Assessment Factory Acceptance Testing Installation Qualification 10

User Requirement Specification (URS) A description of the requirements of the facility (project) in terms of product to be manufactured, required throughput and conditions in which the product should be manufactured. Approved statements prepared by the user which defines what is required by the project. 12
- 13. Design Qualification (DQ) Documented review of the design, at an appropriate stage in a project, for conformance to operational and regulatory expectations. (Note : Not an obligation) 13
- 14. Impact Assessment The process of evaluating the impact of the operating, controlling, alarming and failure conditions of a system on the quality of a product 14
- 15. Factory Acceptance Testing (FAT) Inspection and static and/or dynamic testing of systems or major system components to support the qualification of an equipment system conducted and documented at a supplier site. (Note : Not an obligation) 15
- 16. Documented verification that all aspects of a facility, utility or equipment that can affect the product quality adhere to approved specifications and are correctly installed. The process of checking/verifying the installation to ensure that the critical components meet the approved specifications and that they are installed correctly in accordance with design documentation. 16
- 17. To establish that the critical components are installed correctly and in accordance with design documentation requirements (i.e. PO’s, Contracts etc.), that supporting documentation is in place and of suitable quality.

- 21. After protocol execution is complete and deviations evaluated, post execution approval is required. Requires sign off by original signatories. IQ execution should be complete and approved prior to the start of OQ. 21
- 22. Calibration Demonstrating that a measuring device produces results within the specified limits of those produced by a reference standard over an appropriate range of measurements. The devices are normally tagged and supported by a maintenance procedures. 22
- 23. Site Acceptance Testing (SAT) Inspection and dynamic testing of systems or major system components to support the qualification of an equipment system conducted at a client site. (Note : Not an obligation) 23
- 24. Documented verification that all aspects of a facility, utility or equipment that can affect product quality operate as intended throughout all anticipated ranges. It is the process of testing to ensure that individual components and systems operate as specified, and how that information is recorded. 24
- 25. To establish through documented testing, that all critical components and direct impact systems are capable of operating within established limits and tolerances. To test parameters that regulate the process or product quality. To verify the proper operation of controllers, indicators, recorders, alarms and interlocks, is performed and documented during the operational qualification testing. 25

- 28. Parameters Have all Installation Qualification been completed for this system? Is the system clean and free from dirt? Is the direction of the rotation of agitator correct? Check the operation of the agitator emergency stop? Check the operation of all agitator controls, both on the main and local panels? Check that the agitator in the vessel free to turn? Pressurize the vessel and record the pressure drop for 10 min. Perform a vacuum test and record the vacuum drop. 28
- 29. Documented verification that all aspects of a facility, utility or equipment that can affect the product quality perform as intended in meeting the predetermined acceptance criteria. 29
- 30. To integrate procedures, personnel, systems and materials to verify that the utility / environment / equipment / support systems produces the required output. This output may be a product contact utility, sterilization condition or environment. 30

- 32. Process Validation The documented verification providing a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes. The new guidelines aligns process validation activities with a product life cycle concept. 32

- 34. Life Cycle of the product & the process Stage 1 – Process Design Stage 2 – Process qualification Stage 3 - Continuous process verification 34
- 35. It is the activity of defining the commercial manufacturing process that will be reflected in planned master production and control records. The goal of this stage is to design a process suitable for routine commercial manufacturing that can consistently deliver a product that meets its quality attributes. It is based on the knowledge gained through development & scale-up activities. 35
- 36. During this stage, the process design is evaluated to determine if the process is capable of reproducible commercial manufacturing. The products manufactured during this stage, if acceptable , can be released for distribution. Two Aspects Design of facility and qualification of equipment and utilities. Process Performance Qualification ( PPQ). 36
- 37. Def.: “Releasing for distribution a lot of finished product, manufactured following a qualification protocol, that meets the standards established in the protocol, but before the entire study has been executed”. Orphan Drugs Specific drug for specific use Shor t Shelf-life radio pharmaceuticals 37
- 38. The goal of this stage is continual assurance that the process remains in a state of control ( the validated state) during commercial manufacture. The cGMP requirements, specifically the collection & evaluation of information & data about the performance of the process will allow detection of undesired process variability. This stage is also applicable for legacy products. 38
- 39. Change Control Formal evaluation of the potential impact of planned modifications on the validated status of a product, process or facility. 39
- 40. Training personnel for IQ/OQ execution. The purpose of the equipment/ system. Use of test equipment Applicable SOP’s cGMP documentation of training Document all training Periodically review training requirements 40
- 41. A document that summarizes and analyses the test results at the end of PQ. Provides a conclusion about the ability of the system to consistently meet acceptance criteria. May be a stand alone document at each stage of IQ/OQ and PQ to summarize results. 41

- 51. Major change in cleaning procedure Change in cleaning agent New equipment 51
- 52. Knowledge of the materials - Potency of the drug - Pharmacological and toxic properties - Degradation products - Cleaning agents - Micro residues 52

- 54. MAC = TD x BS x SF / LDD MAC = Maximum Allowable Carryover TD = Single Therapeutic Dose BS = Batch size of next product to be manufactured on the same equipment. SF = Safety Factor LDD = Largest Daily Dose of the next product in the same equipment. 54
- 55. Ranitidine Tablets - Ibuprofen Tablets TD = Single Therapeutic Dose = 150 mg Ranitidine-Tab BS = Batch Size = 100 kg of Ibuprofen SF = Safety Factor = 1/1000 LDD = Largest Daily Dose of the next product in the same equipment = 200 mg X 5 tablets of Ibuprofen MAC = Max Allowable Carryover = 150 X 100 X 1000 x 1000 X 1/1000 X 1/1000 i.e 15000 mg in 100 kg Batch size i.e 150 mg in 1 kg = 150 ppm 55
