Recast of the IVD Directive
-Biggest change since the directive was introduced in 2000.
-Exact details are not yet confirmed – though the main
proposed changes have been known since end 2011.
-The proposed changes have been discussed at BIVDA
and EDMA meetings and feedback has been given.

Four Key Impacts:
1. Clinical Evidence
2. Classification of Medical Devices
3. Conformity Assessment
4. UDI/Barcoding.
(Based upon the version reviewed by the Medical Device Expert Group
on 13th February 2012)
1. Clinical Evidence
“The demonstration of conformity… shall be based upon clinical
evidence.”
“The clinical evidence report shall contain a scientific validity
report, an analytical performance evaluation report and where
appropriate, a clinical performance report.”
“Clinical performance means the ability of a device to yield
results that are correlated with a particular clinical condition...”
Why does this pose a significant impact?
1. This is a new requirement.
2. Clinical evidence reports will be needed for 200+ IVD
products.
3. No “grandfathering” – existing products are not exempt.
Cont’d
Why does this pose a significant impact?
4. Generating the necessary data with patient groups would
be very time-consuming and expensive. Unclear how much
existing literature/publications can be used.
5. The use of positive/negative predictive values and
likelihood ratios have been suggested previously - may be
impossible to define for many IVD tests which are used as
part of a panel rather than stand-alone.
2. Classification of IVD Medical Devices
Reminder of current classification:
1. Annex II A – Very high risk (HIV, Hepatitis, ABO, Rhesus
Blood grouping).
2. Annex II B – High risk (anti-Duffy, Kidd blood grouping,
erythrocytes, rubella, toxoplasmosis, PKU, CMV,
chlamydia, HLA tissue groups, PSA, trisomy 21, blood
glucose self-test).
3. Self Test Devices.
4. “The rest” (also known as Annex III) – Low risk, selfcertification
New Classification – based on the GHTF system.
Already adopted/adapted by several countries – Australia, China,
Canada, Singapore.
Class A: Instruments (except self & near patient testing), specimen
receptacles, reagents with specific characteristics intended to make
them suitable for IVD procedures related to a specific examination.
Class B: All non-class A, C and D.
Class C: Sexually transmitted agents, infectious agents in blood, CSF,
infective disease/immune states which would lead to patientmanagement decisions resulting in life-threatening situations. Devices
used in companion diagnostics for disease staging, used in screening
or diagnosis of cancer, genetic testing.
Class D: Detect transmissible agents in blood components, blood cells,
tissues for transplantation, transmissible agents causing life-threatening
diseases.
Why does this pose a significant impact?
Several tests have gone “up a class”, including cancer
diagnosis/screening tests. The concern over this becomes
apparent when considering Conformity Assessment.
3. Conformity Assessment
Under current system, the large majority of IVDs on the
market are the low-risk “Annex III” products which are selfcertified as compliant with the IVD Directive by their
manufacturers, usually supported by an externally
inspected ISO9001/ISO13485 quality system.
This allows companies to bring new products quickly to the
market, also to manufacture, release and modify products
without time-consuming external approvals.
New Conformity Assessment
Under the new system:
“Manufacturers of Class C devices…shall be subject to
conformity assessment based on product quality assurance
and design dossier examination”.
Why does this pose a significant impact?
Binding Site would have to appoint a Notified Body for its
Freelite product range, since these tests are used in the
diagnosis of multiple myeloma, a type of cancer. This would
add a significant annual cost and potentially restrict
development and time-to-market for this product area.
But there is more….
New Conformity Assessment
Under the new system:
“Manufacturers of Class B devices…shall be subject to
conformity assessment based on full quality assurance”
This is essentially a level of Notified Body involvement for
by far the largest group of IVDs (affecting all Binding Site’s
diagnostic products). A very significant extra workload and
expense.
There is also concern about the availability of enough
suitably-experienced Notified Body staff to handle this
considerably increased workload across the industry!
4. UDI/Barcoding
New EU and US guidance has been recently published:
1. European Commission recommendation on a common
framework for a unique device identifier system in the EU.
2. FDA (USA) Proposed Rule…to establish a unique device
identification system…
The main driver for UDI/barcoding is product safety – by
better product identification and traceability, recalls will be
more effective, incident reporting will be improved etc.
Other benefits related to stock management, anticounterfeiting and distribution control are anticipated.
There has been collaboration between the EU and US
authorities to try to ensure the two sets of requirements are
compatible. Other countries that are also currently looking
at UDI/barcoding (China, Australia) will be watching with
interest….
It is important to emphasize that the UDI/barcoding
requirements will almost certainly come into force before
the other requirements of the recast IVD Directive.
Key Requirements of the UDI/Barcoding guidelines:
1. National databases will need to be set up to hold the
product data. It is hoped that a single database can be
used to cover the whole of the EU.
Key Requirements of the UDI/Barcoding guidelines:
2. Manufacturers will need to provide a UDI/barcode on the
label of each medical device comprising a “static” part and
a “dynamic” part.
Key Requirements of the UDI/Barcoding guidelines:
3. Manufacturers will supply “fixed” data to each national
database linked to the “static” part of the UDI. This fixed
data is likely to include product code, product name,
storage temperature, national registration number etc.
Key Requirements of the UDI/Barcoding guidelines:
4. The “dynamic” part of the UDI, comprising lot number or
serial number or expiry date, will be added by the
manufacturer at the time of production. This information will
not be supplied to national databases.
Why does this pose a significant impact for
Binding Site?
1. An internal database to collate all of the “static”
information will need to be set up – in a format that can be
easily submitted to national databases.
2. Barcoding technology will need to introduced across the
product range (Binding Site does not currently barcode its
products). This will include new printers, readers and
additional quality control checking.
Cont’d
Why does this pose a significant impact for
Binding Site?
3. All outer product labels will need to be redesigned to
incorporate the barcode. This could cause problems for
smaller products where space on the label is severely
limited.
4. A decision must be taken on whether to adopt the old
1-dimensional the newer 2-dimensional barcode format.
The US UDI proposal is currently out for comment, but is
expected to be in place by May 2013. Medium risk products
(most IVDs) will then need to comply by May 2016. (High
risk products earlier).
The European requirements are expected to be in place by
the same time as the US requirements or shortly
afterwards.
What’s Next?
Binding Site have fed back their comments through BIVDA
and EDMA, so now we await the publication of the
proposed IVD Directive when it is passed to the European
Parliament this autumn.
Updates on the UDI requirements are expected before the
end of 2012.
Thank you for listening.
