Definition Change – Any addition to, deletion of, or modification to any approved / authorized procedures, process, materials or product is defined as a change. A formal system to evaluate, document, approve and implement changes that might affect the validated status of facilities, equipment and process. A change is a permanent planned alteration to any approved process or procedure that may affect the safety, quality and efficacy of blood component. CCF is a process that ensure changes to material, method, equipment, process, facility are properly documented, validated, approved & traceable.
Scope Master Documents Specifications Test Procedure Master Formula Manufacturing Process Facility, Equipment, Area Other Documents Software, PLC, Instruments, Server SAP, ERP Planned Deviation (Temporary Changes) SOPs
Change in specification and method of analysis: Revision of specification limits Change in analytical procedure Pharmacopoeial changes Tightening or relaxation in manufacturing specification Addition or deletion of test Change in document template Inclusion of additional instruction/ simplification or editorial changes without changing actual method of analysis and specification limit Other product specific changes New-product introduction Change in vendor of product specific starting materials Change in starting material manufacturing process Change in customer of product Change in storage condition based on destination market Change in master formula records Addition or deletion of stability study condition Extension or reduction of product shelf life
2. General changes: Change on Standard Operating Procedure (SOP) Facility change Equipment change Modification of equipment Upgrade equipment or system software Permanent change in working shift timing Change in layouts and drawings Modification of facility Heating Ventilation and Air Conditioning (HVAC) system modification Revision of documents, such as, Site Master File, Validation Master Plan, Quality Manual, Protocols, or any other GMP documents
Change control procedure-Flow chart
Classification of change control Major : A change that would be likely to have a significant impact on quality attributes of a process, material, product, procedure, and registration requirements. Major changes are those changes that have a direct impact or potential impact on the product quality, safety, strength, identity, efficacy, and purity of a product, validation status of the process, equipment, utility, facility or GMP compliance, procedures, systems or regulatory filings. Minor : Minor changes are those changes that do not have a direct impact or potential to have a direct impact on the product quality, identity, safety, strength, purity, and efficacy of a product or validation status of the process, equipment, utility, facility or GMP compliance/ procedures, and systems or regulatory filings.
Table: 1 – Classification of change control Major changes Minor changes Changes do not require change control Modification of manufacturing facility Introduction of new product Change in batch size Change in manufacturing equipment Change in specification of product or product component Change in HVAC design Modification of equipment or change in critical component of equipment e.g. change in motor or Rapid Mixture Granulator, modification of RABS in the aseptic area Change in document template Periodic review of Standard Operating Procedure or any other documents Adding additional instruction in the batch record or analytical method without changing core process Modification of lifting device Change of laundry for work in non-sterile and non-potent drug manufacturing facility Facility modification outside manufacturing area, e.g. modification of office area furniture, pipeline modification in garden, modification of road surrounding the building Replacement of change part of equipment (like to like) Replacement of HVAC motor with similar capacity Installation of air conditioning system in staff room
Types of Change control 1. Permanent changes: Permanent changes mean the changes that remain in effect till the next required revision or modifications. 2. Temporary change controls: A change that is implemented for a specific predetermined period. Temporary change controls are also called planned deviation by some of the organizations. Evaluation & Action Plan Evaluation of impacted areas done by respective departments. Evaluation of impacted documents. Identify action plan related to impacted areas.
Table: 2 – Parameters to be considered for impact and risk assessment for change control evaluation Sr. no Impact of change to be evaluated for Sub sections 1 Facility approvals Site approval status Approvals for additions of facility or expansions Layout approvals Any other legal approvals 2 Buildings and facilities Facility concept design Building design approval Validation master plan for the facility Direct impacting utility requirements and design Layout design for material movements, AHU distribution, pressure zoning, classification layouts, HVAC ducting layouts Service area design Environment/ classification requirement Rodent and pest control design Drainage layouts Facility blue print Facility qualification
3 Equipment/ instrument Identification of equipment/ instrument Requirement of vendor support for list of activities User Requirement Specification (URS) Design Qualification (DQ) Factory Acceptance Test (FAT) Site Acceptance Test (SAT) Installation Qualification (IQ) Operation Qualification (OQ) Performance Qualification (PQ) Preventive maintenance program and schedule Calibration of instrument and schedule Equipment list List of spare parts Supporting utility requirement Annual Maintenance Contract Re-qualification/ re-validation program Passivation of equipment Data backup User rights Discontinuation of equipment Data archival Process validation Cleaning validation

11 Aseptic processing Media fill Environmental monitoring Media fill matrix Media fill protocol Media fill batch record Visual inspection qualification Approval Evaluation & action plan of impacted verification by QA. Change control approval by QA Head. After approval of change control submit to QA.
Trending of change controls Trending of changes in the facility is very important to monitor and control the changes. Changes which were rejected, cancelled, major changes, open changes etc. are required to be closely monitored and trended. During regulatory inspections, primary focus are major changes, facility related changes, rejected changes etc. Closing of Change control Implementation of identified action plan within TCD. Submit all implemented documents to QA for verification. Close the change control by QA Head.
Determination of Notification to the Agency PAS: • A change in a regulatory analytical procedure that does not provide the same or increased assurance of the identity, strength, quality, purity, or potency of the material being tested as the regulatory analytical procedure described in the approved application. CBE-30: • Any change in a regulatory analytical procedure other than those identified as major changes or editorial changes. CBE-0: • A change in an analytical procedure used for testing components, packaging components, the final intermediate, in-process materials after the final intermediate, or starting materials introduced after the final intermediate that provides the same or increased assurance of the identity, strength, quality, purity, or potency of the material being tested as the analytical procedure described in the approved application. Annual Report: • For drug substance and drug product, the addition or revision of an alternative analytical procedure that provides the same or increased assurance of the identity, strength, quality, purity, or potency of the material being tested as the analytical procedure described in the approved application or deletion of an alternative analytical procedure.
