Computer System Validation EU Anne-11 Guideline Lesson-5




EudraLex EU Annex -11

Introduction :- EU GMP Annex 11 for computerized systems has been an Active  part of EU GMP since 1992. In 2008, the European Medicines Agency issued a proposed update that also consisted of a Principle and 19 clauses but the length of text was four times as long as the current version. This was a major change to the regulation that incorporated regulatory concerns noted by inspectors with all types of computerized systems. There were also consequential changes to Chapter 4 on documentation that were also issued for industry comment. Within the six month comment period, over 1,400 responses from industry were received by the Agency.
The final version of Annex 11 was issued in January 2011 and becomes effective on 30th June 2011. The structure of the released document has a Principle and 17 clauses but the text is still longer than the current version it replaces. Some of the more stringent requirements from the 2008 draft have been removed from the final version of the regulation.
Major changes in Annex 11 include:
  v  Applications must be validated IT infrastructure must be qualified
  v  risk management in both computer validation and change control 
  v  The life cycle validation phase has been extensively expanded 
  v  Requirements traceability throughout a life cycle moves from a regulatory expectation to a regulatory requirement for the first time.
  v  New requirements for data integrity, availability and confidentiality 
  v  Vendor audit reports should be available for inspectors to review .
  v  Explicitly allows the use of electronic signatures for signing documents including records

Principle:-  This annex applies to all forms of computerized systems used as part of a GMP regulated activities. A computerized system is a set of software and hardware components which together fulfill certain functionalities. The application should be validated; IT infrastructure should be qualified. Where a computerized system replaces a manual operation, there should be no resultant decrease in product quality, process control or quality assurance. There should be no increase in the overall risk of the process.

The principles of Annex 11 and the new section on risk management will be discussed and compared with the old version to understand the impact of the changes in these sections. 

Scope : Qualify IT infrastructure and validate applications
Risk management in computer validation – Has anything changed in the new version.

Roles and Responsibility in Computerized System Validation: - The new Version of  EU added part of Roles and Responsibility.
v  Process Owner
v  System Owner
v  Information Technology
v  Supplier
v  Service Provider
Data Integrity Requirements for Computerized Systems :- The requirements for data integrity are split over several clauses of Annex 11 and we will explore the updated sections for this topic as follows: „
v  Accuracy checks 
v  Printouts of data        
v  Audit trail requirements

Regulatory Issues around the Information Technology Department

Security of Networks and Computerized Systems:-  Physical and/or logical controls should be in place to restrict access to computerized system to authorized persons. Suitable methods of preventing unauthorized entry to the system may include the use of keys, pass cards, personal codes with passwords, bio-metrics, restricted access to computer equipment and data storage areas.
v  The extent of security controls depends on the criticality of the computerized system.
v  Creation, change, and cancellation of access authorizations should be recorded.
v  Management systems for data and for documents should be designed to record the identity of operators entering, changing, confirming or deleting data including date and time.

Security is a key requirement of computerized systems, applications and networks;

v  Security of networks and applications 
v  Access control requirements in the new Annex 11 „
      ·        Procedures and records for security and access control
Batch Release :- When a computerized system is used for recording certification and batch release, the system should allow only Qualified Persons to certify the release of the batches and it should clearly identify and record the person releasing or certifying the batches. This should be performed using an electronic signature
Change Control and Configuration Management :- Change control is an existing requirement of Annex 11; the clause has been streamlined in the new version. However the title also mentions configuration management but does not define the term which is confusing as there are at least two definitions used in software engineering. „
  v  Review and interpretation of the new Annex 11 requirements „
  v  Issues in implementing the requirements

Electronic Signatures:- Electronic records may be signed electronically. Electronic signatures are expected to: a. have the same impact as hand-written signatures within the boundaries of the company, b. be permanently linked to their respective record, c. include the time and date that they were applied. Electronic Signature requirement same as CFR 21 Part -11.

New Requirements for Vendor Audits:-  Annex 11 mandates that vendor audit reports should be available for review by inspectors, this talk will explore the issues surrounding this area.
v  Identifying the changes in approach from the old to the new version of Annex 11 
v  What will this mean for vendor audits in the future? „
v  Will vendor management be an undocumented requirement for software suppliers that fail audits?

GMP Chapter 4 on Documentation: What are the major changes? The new version of Chapter 4 was revised in the light of the increasing use of electronic documents within the GMP environment and it brings requirements for the definition of raw data and the handling of electronic records. 

  v  Types of records: Site Master File, instructions and records / reports „ Definition of electronic raw data.
  v  Management requirements of electronic records
  v  Hybrid and electronic systems under EU
  v  Retention of documents

Periodic Evaluation of Computerized Systems:-  The new version of Annex 11 formalizes the periodic review of computerized systems and the talk will present the regulatory requirements and practical interpretation of them. 
Computerized systems should be periodically evaluated to confirm that they remain in a valid state and are compliant with GMP. Such evaluations should include, where appropriate, the current range of functionality, deviation records, incidents, problems, upgrade history, performance, reliability, security and validation status reports.

Requirements of the new Annex 11 

Practical interpretation of the new requirements – are all systems the same?

Change and Configuration Management :-  Any changes to a computerized system including system configurations should only be made in a controlled manner in accordance with a defined procedure.

Audit Trails Consideration should be given, based on a risk assessment, to building into the system the creation of a record of all GMP-relevant changes and deletions (a system generated "audit trail"). For change or deletion of GMP-relevant data the reason should be documented. Audit trails need to be available and convertible to a generally intelligible form and regularly reviewed.

Incident Management:- All incidents, not only system failures and data errors, should be reported and assessed. The root cause of a critical incident should be identified and should form the basis of corrective and preventive actions.

Archiving:-  Data may be archived. This data should be checked for accessibility, readability and integrity. If relevant changes are to be made to the system (e.g. computer equipment or programs), then the ability to retrieve the data should be ensured and tested.

Data Storage:- Data should be secured by both physical and electronic means against damage. Stored data should be checked for accessibility, readability and accuracy. Access to data should be ensured throughout the retention period.
Regular back-ups of all relevant data should be done. Integrity and accuracy of backup data and the ability to restore the data should be checked during validation and monitored periodically.

Validation
v  The validation documentation and reports should cover the relevant steps of the life cycle. Manufacturers should be able to justify their standards, protocols, acceptance criteria, procedures and records based on their risk assessment.
v  Validation documentation should include change control records (if applicable) and reports on any deviations observed during the validation process.

v  An up to date listing of all relevant systems and their GMP functionality (inventory) should be available. For critical systems an up to date system description detailing the physical and logical arrangements, data flows and interfaces with other systems or processes, any hardware and software pre-requisites, and security measures should be available.
v  User Requirements Specifications should describe the required functions of the computerized system and be based on documented risk assessment and GMP impact. User requirements should be traceable throughout the life-cycle.
v  The regulated user should take all reasonable steps, to ensure that the system has been developed in accordance with an appropriate quality management system. The supplier should be assessed appropriately.
v  For the validation of bespoke or customized computerized systems there should be a process in place that ensures the formal assessment and reporting of quality and performance measures for all the life-cycle stages of the system.
v  Evidence of appropriate test methods and test scenarios should be demonstrated. Particularly, system (process) parameter limits, data limits and error handling should be considered. Automated testing tools and test environments should have documented assessments for their adequacy.
v  If data are transferred to another data format or system, validation should include checks that data are not altered in value and/or meaning during this migration process
