Every year, US-FDA organises a conference in Washington, DC, that is
co-organised by PDA.
This year's event dealt with an interesting spectrum of topics, even
though several announced FDA guidance documents could not be presented yet
in a printed version. However, most of their content got discussed
already.
The conference was strictly focussed on FDA related issues only by
topics and choice of speakers. Among the more than 50 speakers, there was
none from the European pharmaceutical industry. And, only one speaker from
a European competent authority was invited for a presentation: Dr. Joerg
Neuhaus from the Cologne Inspectorate is one of the few European GMP
inspectors well recognised in the US. As an expert for aseptic processing,
biotechnology/blood products and GMPs in development, he is one of the
most sought-after specialists.
We asked Dr. Neuhaus to share his impressions on the most interesting
topics of the conference. (Oliver Schmidt on behalf of ECA)
Here are his minutes:
The really interesting innovations could be found in relation to those
topics on which the US-FDA has published guidances or started initiatives
in the recent years. FDA representatives stated that this was due to FDA's
intention to finalise the guidance documents first and then to review the
corresponding inspection and compliance programs. Therefore, we can expect
some interesting surprises in this area soon, clues for which could
already be found at the conference.
A number of sessions were held on Process Analytical Technology (PAT).
Here, the FDA has not yet come to a finalised position. Obviously, they
are looking for the right concepts, still. The fact that currently only 2
PAT projects of industry have obtained FDA's approval and 18 further
projects have well progressed in evaluation may be indicative for that.
In the field of process validation, the FDA has developed its
expectations further and adopted some of the European positions.
Therefore, the 3 validation batches that were mandatory in the past are
not considered to be sufficient any longer. Now they are regarded as
"conformance batches" only. FDA expects more evidence of quality
capability and control of processes from validation now. To reach this aim
in validation, a thorough understanding of the process has to be
established and maintained following a life cycle concept. It was
announced that a draft of a revised process validation guide will be
published before the end of 2005. Therefore, it is useful to keep up to
date with this development.
Regarding aseptic processing, it could be observed that FDA is
definitely changing its paradigm orientating more towards the risks for
product and patients. The respective training of FDA inspectors is good in
progress. Therefore, immediate effects on the inspection practice may be
expected soon. Additionally, the FDA emphasises its intention to reward
modern risk minimising technologies. E.g., it is intended to decrease the
requirements on isolators in comparison to conventional clean room
technology. And, FDA announced to define, among others, a new category of
Restricted Access Barriers (RABS) processing devices. These are
"almost-isolators", which are intended to be rewarded by reduced
requirements, too.
In September 2004, FDA published a "Draft Guidance for Industry:
Quality Systems Approach to Pharmaceutical Current Good Manufacturing
Practice". This document outlines requirements on quality systems for
pharmaceutical manufacturers. The document is intended to resolve the
discrepancy that FDA's current cGMP regulations (21 CFR 210/211) do not
include any references to quality systems. With this draft, the FDA
extends the principles of the Quality Systems Inspection Technique (QSIT)
concept, which has been successfully established in the field of medical
devices (Center for Devices and Radiological Health), to medicinal
products and biologicals. It is most probable that the final
"Guidance for Industry: Quality Systems Approach to Pharmaceutical
Current Good Manufacturing Practice" will be published by the end of
the year. FDA has stated that it will not wait with its initiative until
an ICH Q10 document on quality systems has been published. However, FDA
has announced that its own guidance will be withdrawn or modified
respectively as soon as ICH has finalised Q10. [ECA:
Compare the event: FDA's New Quality Systems
and Risk Approach with former FDA Deputy Director Jim Lyda]
Way behind these almost completed projects, there was little progress
only on how to revise 21 CFR Part 11 and the corresponding guidances on
computerised systems. It needs a lucky star that 2005 will see a
publication of first drafts.
In a session on ICH Q10 (Quality Assurance Systems), industry
representatives expressed their high demands that the harmonisation of
quality assurance systems should be accomplished by a facilitation of
regulatory change procedures. However, the ICH process has not yet moved
beyond the agreement to tackle Q10. So far, no concept has been developed.
Nevertheless, the delegates of the interested parties present at the
conference emphasised their intention to expedite the process and to
complete it successfully in 12 to 18 months due to the high interest from
the industry.
It is remarkable that - during several side discussions - FDA
representatives repeatedly emphasised their conviction that a future US
PIC/S membership would result in great progresses - not only with regard
to harmonisation. The author received information outside the conference
that the membership application has been submitted to the PIC/S office
meanwhile and the PIC/S member authorities charged with the evaluation
have already been selected (UK and France).
In total it can be summarized that US-FDA continues to fill its cGMP
Initiative for the 21st Century and its Risk-Based Approach
concept with life more and more. A very positive result!
