New EU Requirements for Qualification & Validation

 

Updated version of Annex 15 ◦ Qualification and Validation

Draft released in February 2014

Final version released on the 30th of March , 2015

Will be effective on 01 October 2015 4/3/2015 3

Improved Annex 15

May be used as supplementary optional guidance for active substances without introduction of additional requirements to EudraLex, Volume 4, Part II.

Retrospective validation is no longer an acceptable approach

The term “validation” has been replaced with “qualification and validation” to reflect the true intent of the Annex 15 in several instances.

An “equivalent document” to a VMP may be used for qualification and validation planning

VMP no longer needs to include –

  • Protocol and report templates,
  • scheduling and planning information
  • Confirmation of materials and suppliers used

For large and complex projects separate validation plans may be used

  • The importance of Quality Risk Management is evident
  • Risk assessment to be repeated if further knowledge and understanding is gained from any changes during the project phase or during commercial production.
  •  Data integrity is also mentioned were “appropriate checks” needs to be built into qualification and validation tasks “to ensure the integrity of all data obtained”.

Current version of Annex 15 of the EU Guide to GMP

  • Originally published in September 2001
  • Significant changes in the GMP environment
  • Advancements in manufacturing technology and continuous manufacture processes.
  • Many changes to other Chapters and Annexes which have an impact on Annex 15
  • Current version of the US FDA Guide on Process Validation,
  • Approaches in ASTM E2500-07 “Standard Guide for Specification, Design, and Verification of Pharmaceutical and Bio-pharmaceutical Manufacturing Systems and Equipment “
  • All the above has justified the change.

This revision to Annex 15 takes into account

  • Changes to Other sections of the EudraLex, Volume 4, Part I ◦ Relationship to Part II
  • Annex 11
  • ICH Q8, Q9, Q10 and Q11
  • QWP guidance on process validation
  • Changes in manufacturing technology

Qualification Stage for Equipment,Facility,Utilities and system

Qualification activities

Consider all stages

Initial development of the user requirements specification through to End of use of the equipment, facility, utility or system.

The main stages and some suggested criteria which could be included in each stage are indicated in subsequent slides:although this depends on individual project circumstances and may be different.

User requirements specification (URS)

Define specification in a URS and/or a functional specification for

  • Equipment
  • Facilities
  • Utilities or systems
  • The essential elements of quality need to be built in at this stage
  • GMP risks if any should be mitigated to an acceptable level.
  • URS should be a point of reference throughout the validation life cycle.

Design qualification (DQ)

  • The next element in the qualification of equipment, facilities, utilities, or systems.
  • Demonstrate compliance of the design with GMP
  • Document compliance
  • Verify requirements of the user requirements specification during the design qualification.

Factory acceptance testing (FAT) /Site acceptance testing (SAT)

  • Equipment may be evaluated at the vendor prior to delivery.
  • Confirm compliance with URS/functional specification prior to installation at the vendor site
  • Documentation review & some tests could be performed at the FAT or other stages
  • These tests need not be repeated on site at IQ/OQ if functionality is not affected by transport and installation.
  • FAT may be supplemented by the execution of a SAT following the receipt of equipment at the manufacturing site.

Installation qualification (IQ)

Perform IQ on

Equipment

Facilities

Utilities

Systems.

IQ should include, but is not limited to the following:

  • Verification of the correct installation of components, instrumentation, equipment, pipe work and services against the engineering drawings and specifications;
  • Verification of the correct installation against pre-defined criteria;
  • Collection and collation of supplier operating and working instructions and maintenance requirements;
  • Calibration of instrumentation
  • Verification of the materials of construction.

Operational qualification (OQ)

  • OQ normally follows IQ
  • May be performed as a combined Installation/Operation Qualification (IOQ).
  • Depends on the complexity of the equipment.

OQ should include but is not limited to the following:

Tests that have been developed from the knowledge of processes, systems and equipment to ensure the system is operating as designed;

Tests to confirm upper and lower operating limits, and /or “worst case” conditions.

Performance qualification (PQ)

PQ should normally follow the successful completion of IQ and OQ.

Could also be performed in conjunction with OQ or Process Validation.

PQ should include, but is not limited to the following:

  • Tests using
  • Production materials,
  • Qualified substitutes or
  • Simulated product proven to have equivalent behaviour
  • Normal operating conditions
  • Worst case batch sizes.
  •  Justify the frequency of sampling used to confirm process control
  • Tests should cover the operating range of the intended process
  • No need for this if documented evidence from the development phases confirming the operational ranges is available.

RE-QUALIFICATION

Evaluate at an appropriate frequency to confirm that following remain in a state of control

  • Equipment
  • Facilities
  • Utilities
  • Systems

Justify re-qualification period

Define criteria for reevaluation

Assess the possibility of small changes over time.

 

Process Validation

General Principles

  •  Applicable to the manufacture of all pharmaceutical dosage forms.
  • Initial validation of new processes
  • Subsequent validation of modified processes
  • Site transfers and ongoing process verification.
  • Robust product development process required to enable successful process validation.
  • This guidance should be used in conjunction with the current EMA guideline on Process Validation for Finished Products.
  • Guidance on information and data to be provided in the regulatory submission only.
  • However GMP requirements for process validation continue throughout the lifecycle of the process.
  • Apply this approach to link product and process development.
  • Manufacturing processes may be developed using a
  • Traditional approach
  • Continuous verification approach
  • Before any product is released to the market & irrespective of the approach used
  • Processes must be shown to be robust
  • Ensure consistent product quality.

Traditional approach

  • Only prospective validation programme prior to certification of the product.
  • Retrospective validation is no longer an acceptable approach.

New products

  • Cover all intended marketed strengths
  • Cover all sites of manufacture
  • Bracketing could be used. Justify based on,1. Extensive process knowledge from the development stage,2. An appropriate ongoing verification programme

Site Transfer

  • Transferred from one site to another
  • Within the same site
  • Number of validation batches could be reduced by the use of a bracketing approach. Justify based on
  • Existing product knowledge,
  • Content of the previous validation

Use bracketing for

  • Different strengths
  • Batch sizes
  • Pack sizes
  • Container types

Site Transfer of Legacy products

  • Manufacturing process and controls must comply with the marketing authorisation
  • Meet current standards for marketing authorisation for that product type.
  • If necessary, variations to the marketing authorisation should be submitted.

Attributes and parameters

  • Important for ensuring the validated state and acceptable product quality
  • Process validation should establish whether these can be consistently met by the process
  • Document the basis for identifying criticality of parameters & attributes.

Process validation batches

  • Same size as the intended commercial scale batches
  • Justify use of any other batch size

Development studies & Process knowledge
