Validation – updating the standards
For a good year now the 15th
supplementary guideline to the EC-GMP Guide (Annex 15) has been available
in draft form (see GMP-News no. 54). The commentary on this draft was
completed by spring of this year.
A very well-founded commentary of the PDA
is explained below:
The main focus of the PDA is on the
compatibility of Annex 15 with other bodies of regulations of the ICH
regions (EU, USA, Japan) which also deal with the topic of validation.
The PDA also desires this compatibility
for the document "Guidance on Process Validation" (CPMP/QWP/848/96/draft)
issued by the CPMP (Committee for Proprietary Medicinal Products), the
medicinal products specialty committee of the European regulatory
authority EMEA (European Medicinal Evaluation Agency).
Furthermore, a stricter separation
between validation aspects of pharmaceutical production and the
manufacture of active pharmaceutical ingredients (ICH Q7a) is desired.
The desire for less regulation of details
as regards process validation ("Process validation is a dynamic
discipline requiring scientific judgement") is very well formulated.
It is also criticized that Annex 15 has a
"tutorial tone". This is the result of the adoption of contents
from the PIC/S document PR 1/99-1. This document primarily addresses
inspectorates and not industry. For this reason it is desired that it be
shortened in order to achieve comparability with the other supplementary
guidelines.
Inconsistencies between individual terms
within the document (text and definitions) are also criticized. The fact
that performance qualification and process validation, which is not
thoroughly accepted in industry, are treated as the same is given as an
example of this.
ISPE (International Society of
Pharmaceutical Engineers) has announced a new baseline on the topic of
qualification entitled " Commissioning & Qualification
Guide" for January 2001.
This document is to define key terms and
enable a consistent and nevertheless flexible interpretation as regards a
"designing, constructing, commissioning and qualifying of facilities,
utilities and equipment".
This is therefore expressly a baseline
which is neither a regulary nor seeks to replace any!
Nor is the topic of process validation
dealt with within the baseline.
The document comprises 13 chapters

Qualification Guide
Its philosophy is:
Placing premises and equipment into
pharmaceutical use on the basis of Good Engineering Practice (GEP)
supplemented by commissioning and, when needed, expanded by qualification.
When needed means, it is only qualified if there is a direct influence on
product quality (direct impact).
This "direct impact" should
already been included in the calculations in order to be able to plan
qualification work in good time.
The baseline understands GEP as applied
engineering art according to the state of the art throughout the entire
processing of the project in order to obtain an effective, cost-effective
solution.
As a new term the baseline introduces
"Enhanced Design Review". It is compared with Design
Qualification as it is described in the draft of Annex 15. The term DQ was
expressly avoided so as not to cause confusion with the design
requirements of FDA as regards medical devices.
Under "commissioning" the
baseline understands well-organized and documented engineering as regards
"start-up" and "turnover" of premises, systems and
equipment. Commissioning leads to a safe and function-oriented environment
which meets the design specifications. Commissioning comprises the
installation of equipment, adjustment work and test runs. It forms the
basis for the installation and operational qualification and should also
be laid down in a plan.
For the qualification work the baseline
requires the active participation of quality assurance, a structured
procedure supported by a corresponding (extensive) documentation and a
change control system. The qualification is based on "Qualification
Rationales".
The V-model already familiar from
computer validation is now also used for "Direct Impact
Systems", and therefore PQ is also integrated:

Qualification Guide
Quality assurance is accorded a far
greater role that has hitherto been the case. It is to be incorporated
into new projects already at a very early stage in order to verify what
qualification work is necessary and how this can be performed within
commissioning. This saves double work and reduces the time input.
Within the framework of the further
training series "Good Validation Practices" we will also inform
you about current developments in the field of validation/qualification in
the coming year, too.
