Good Manufacturing Practices Purpose and Principles of GMP Tony Gould
Why GMP? Provides a high level assurance that medicines are manufactured in a way that ensures their safety, efficacy and quality Medicines are manufactured to comply with their marketing authorization Quality is built in Testing is part of GMP, but alone does not provide a good level of quality assurance 2 PQ Workshop, Abu Dhabi October 2010
Why inspect? Verify compliance with GMP Verify compliance with marketing authorization Dossier: "Dedicated equipment is used" Inspection: Observation that this means "dedicated while used for the product or not being used for another product" Dossier: "The vials are removed from the lyophilliser and crimped in a grade A environment" Inspection: Correct, but before crimping they are stored in an uncontrolled corridor 3 PQ Workshop, Abu Dhabi October 2010

GMP is actually Good Common Sense Quality Management Quality Assurance GMP Production and Quality Control Section 1 and 2 13 PQ Workshop, Abu Dhabi October 2010
Quality management in the drug industry Philosophy and essential elements: "The concepts of quality assurance, GMP, quality control and quality risk management are interrelated aspects of quality management, and should be the responsibility of all personnel. their relationship and their fundamental importance to the production and control of pharmaceutical products." Glossary 14 PQ Workshop, Abu Dhabi October 2010
Quality Management The basic elements are: An appropriate infrastructure or quality system encompassing the organization structure, procedures, processes and resources The systematic actions necessary to ensure adequate confidence that a product (or service) will satisfy given requirements for Quality The totality of these actions is referred to as Quality Assurance 15 PQ Workshop, Abu Dhabi October 2010
The five P's Premises Primary materials People Procedures Processes defined and recorded 16 PQ Workshop, Abu Dhabi October 2010
Quality Assurance Quality assurance is a management tool In contractual situations, it also serves to generate confidence in a supplier QA, GMP and Quality Control are interrelated aspects of Quality Management They are described on the following slides in order to emphasize their relationship and their fundamental importance to the production and control of pharmaceutical products 1.1 17 PQ Workshop, Abu Dhabi October 2010
Quality Assurance Wide-ranging concept covers all matters that individually or collectively influence the quality of a product Totality of the arrangements to ensure that the drug is continuously of the right quality for the intended use Quality Assurance incorporates GMP and also includes product design and development, with special focus on process design 1.1 18 PQ Workshop, Abu Dhabi October 2010
The position of QA Director QA Production QC lab Other Depts 19 PQ Workshop, Abu Dhabi October 2010
Quality Assurance means to assure: Products are designed and developed correctly Complying with, e.g. GMP, GCP, GLP Production and control operations are defined Managerial responsibilities are defined In job descriptions The manufacture, supply and use of correct starting and packaging materials 1.1 a- d 20 PQ Workshop, Abu Dhabi October 2010
Quality Assurance means to assure: (cont'd) Controls are performed, including intermediates, bulk, calibration and validation Correct processing and checking of the finished product Products are sold/supplied only after review by the authorized person Complying with marketing authorization, production and QC requirements Proper storage, distribution and handling 1.1 e - h 21 PQ Workshop, Abu Dhabi October 2010

GMP = continuous urge for improvement Involvement of the management Annual Product Quality Review Quality risk management Complaints handling Self-inspection 27 PQ Workshop, Abu Dhabi October 2010
Involvement of the management The senior management is responsible to attain the company's quality objectives All different departments and all levels within departments should be involved; and it's the senior management who should facilitate this Also suppliers and distributors should be involved The senior management should make available the required resources The basis of the quality system is the quality statement and quality policy, by the senior management 28 PQ Workshop, Abu Dhabi October 2010
Product Quality Review Objectives of Product Quality Review: To review and verify the consistency and appropriateness of the existing process To identify and highlight any trends in the process, e.g. in analytical results, yields etc. To identify any possible product or process improvements 29 PQ Workshop, Abu Dhabi October 2010

Complaints handling Complaints: Principle All complaints and other information concerning potentially defective products must be carefully reviewed according to written procedures and corrective action should be taken. 5.1 32 PQ Workshop, Abu Dhabi October 2010
Complaints Procedure Designated responsible person: To handle complaint Decide on measure to be taken May be authorized person - if not, must advise authorized person of results Sufficient support staff Access to records Written procedure (SOP): Describes action to be taken Includes need to consider a recall (e.g. possible product defect) 5.2 5.3 33 PQ Workshop, Abu Dhabi October 2010
Complaints Procedure cont'd Thorough investigation: QC involved With special attention to establish whether "counterfeiting" may have been the cause Fully recorded investigation reflect all the details Due to product defect (discovered or suspected): Consider checking other batches Batches containing reprocessed product 5.4 5.6 34 PQ Workshop, Abu Dhabi October 2010
Complaints Procedure cont'd Investigation and evaluation should result in appropriate follow-up actions May include a "recall" All decisions and measures taken should be recorded Referenced in batch records Records reviewed - trends and recurring problems 5.7 5.9 35 PQ Workshop, Abu Dhabi October 2010
Complaints - other actions Inform competent authorities in case of serious quality problems such as: Faulty manufacture Product deterioration Counterfeiting 5.10 Have a thorough recall procedure that is consistent with the complaints handling procedure Trend complaints, their investigations and results 36 PQ Workshop, Abu Dhabi October 2010
Self-Inspection Purpose is to evaluate whether a company s operations remain compliant with GMP The programme should cover all aspects of production and quality control be designed to detect shortcomings in the implementation of GMP recommend corrective actions set a timetable for corrective action to be completed Should be performed routinely Also on special occasions such as Recalls Repeated rejections 8.1 37 PQ Workshop, Abu Dhabi October 2010
Self-Inspection (cont'd) Performed by team appointed by management, with: authority sufficient experience, expertise in their own field. knowledge of GMP may be from inside or outside the company Frequency should normally be at least once a year May depend on company requirements Size of the company and activities 8.3, 8.4 38 PQ Workshop, Abu Dhabi October 2010
Self-Inspection (cont'd) Report prepared at completion of inspection, including: results evaluation conclusions recommended corrective measures Follow-up action Effective follow-up programme Company management to evaluate both the report and corrective actions 8.5, 8.6 39 PQ Workshop, Abu Dhabi October 2010
Summary and conclusions: GMP compliance is not an option Quality should be built into the product GMP's are very similar and are really Good Common Sense Good Practices cover all aspects of manufacturing activities prior to supply The role and involvement of senior management is crucial 40 PQ Workshop, Abu Dhabi October 2010
