GUIDELINES RELATING TO THE DEMARCATION BETWEEN DIRECTIVE 90/385/EEC ON ACTIVE IMPLANTABLE MEDICAL DEVICES
DIRECTIVE 93/42/EEC ON MEDICAL DEVICES
AND
DIRECTIVE 65/65/EEC RELATING TO MEDICINAL PRODUCTS
AND RELATED DIRECTIVES
Foreword
The present Guidelines are part of a set of Guidelines relating to questions of
application of EC-Directives on medical devices. They are legally not binding. The
Guidelines have been carefully drafted through a process of intensive consultation of the
various interested parties (Competent Authorities, Commission services, industries and
other interested parties in both the medical devices and the medicinal products sectors)
during which intermediate drafts were circulated and comments were taken up in the
document. Therefore this document reflects positions taken in particular by the
aforementioned interested parties.
These Guidelines describe the demarcation between directives relating to medical
devices and directives relating to medicinal products.

A. DEMARCATION BETWEEN MEDICAL DEVICES DIRECTIVES AND
MEDICINAL PRODUCTS DIRECTIVES
A.1 Introduction
The determination of the borderline between the Medical Devices Directive
93/42/EEC (MDD) (OJ No.L 169, 12/7/93), the Active Implantable Medical Device Directive
90/385/EEC (AIMD) (OJ No. L189, 20/7/90) and the Medicinal Products Directive 65/65/EEC
(MPD) including related directives, was one of the issues discussed at some length during
the legislative procedure on the MDD. Therefore, in the MDD several provisions to
establish the demarcation between both legal regimes have been laid down. It was
recognised that the subject needs to be further explained and illustrated by practical
guidance and examples. The present document has no legal force. It has nevertheless been
elaborated by an expert group including experts from Member States' competent authorities
for both medical devices and medicinal products, the European Commission, as well as
industry trade associations. It is therefore intended that the document will provide
useful guidance which should assist common positions to be taken throughout the European
Union.
For the relevant definitions and legal requirements reference is made to:
| Directive 93/42/EEC MDD |
Directive 65/65/EEC MPD |
Medicinal Products Extension
Directives |
| * Article 1 (2a): "medical
device" |
* Article 1(3) : medicinal product |
Directive 89/343/EEC relating to
radiopharmaceuticals |
| * Article 1 (3): "drug
delivery devices" |
|
Directive 89/342/EEC relating to
immunological products |
| Article 1 (4): "devices
incorporating medicinal substances with ancillary action" |
|
Directive 89/381/EEC relating to
blood products |
A.2 General principles
As a general rule a relevant product is regulated either by the MDD or
by the MPD. The authorization or conformity assessment procedure to be followed prior to
placing a given product on the market will therefore be governed either by the MDD/AIMD or
by the MPD. Normally the procedures of both directives do not apply cumulatively.
For defined features, however, some cross-references are made within one regime to
specific provisions of the other regime (see Article 1(4) in conjunction with Annex I,
section 7.4 MDD; Article 1(3) MDD).
The definitions of medical device and medicinal product are reproduced here for
reference.
Medical device (93/42/EEC)
"Any instrument, apparatus, appliance, material or other article, whether used
alone or in combination, including the software necessary for its proper application
intended by the manufacturer to be used on human beings for the purpose of:
- diagnosis, prevention, monitoring, treatment or alleviation of disease,
- diagnosis, monitoring, treatment, alleviation or compensation for an injury or
handicap,
- investigation, replacement or modification of the anatomy or of a physiological
process,
- control of conception,
and which does not achieve its principal intended action in or on the human body by
pharmacological, immunological or metabolic means, but which may be assisted in its
function by such means;"
Medicinal product (65/65/EEC)
"Any substance or combination of substances presented for treating or
preventing disease in human beings or animals.
Any substance or combination of substances which may be administered to human beings or
animals with a view to making a medical diagnosis or to restoring, correcting or modifying
physiological functions in human beings or in animals is likewise considered a medicinal
product."
In order to decide which regime applies, the following criteria should be examined:
Step 1 The intended purpose of the product taking into account the way the product is
presented (this is likely to establish if either the MDD or the MPD apply, rather than
distinguish between the two regimes),
Step 2 The method by which the principal intended action is achieved.
The latter criterion, based on the "principal intended action" is crucial in
the definition of a medical device. Typically the medical device function is fulfilled by
physical means (including mechanical action, physical barrier, replacement of or support
to organs or body functions, ...). The action of a medicinal product is generally achieved
by pharmacological, immunological means or by metabolism.
The principal intended action of a product may be deduced from:
- the manufacturer's labelling and claims,
- scientific data regarding mechanism of action.
Although the manufacturer's claims are important, it is not possible to place the
product in one or other category in contradiction with current scientific data.
Manufacturers may be required to justify scientifically their rationale for classification
of borderline products.
"Pharmacological means", in the context of the MDD and AIMD, is
understood as an interaction between the molecules of the substance in question and a
cellular constituent, usually referred to as a receptor, which either results in a direct
response, or which blocks the response to another agent. Although not a completely
reliable criterion, the presence of a dose-response correlation is indicative of a
pharmacological effect.
"Immunological means", in the context of the MDD and AIMD, is understood
as an action in or on the body by stimulation and/or mobilisation of cells and/or products
involved in a specific immune reaction.
"Metabolic means", in the context of the MDD and AIMD, is understood
as an action which involves an alteration, including stopping, starting or
changing the speed of the normal chemical processes participating in, and available for,
normal body function.
The fact that a product is itself metabolised does not imply that it achieves its
principal intended action by metabolic means.
Medical devices may be assisted in their function by pharmacological, immunological or
metabolic means, but as soon as these means are not any more ancillary with respect to the
principal purpose of a product, the product becomes a medicinal product. The claims made
for a product, in accordance with its method of action may, in this context, represent an
important factor for its classification as medical device or medicinal product.
These principles are illustrated by bone cements and related products which appear in
several of the following sections. Plain bone cement without antibiotics is a medical
device since it achieves its primary intended purpose (the fixation of a prosthesis) by
mechanical means. Bone cements containing antibiotics, where the principal intended
purpose remains fixation of a prosthesis, are also medical devices. In this case the
action of the antibiotic, which is to reduce the possibility of infection being introduced
during surgery, is clearly ancillary. If however the principal intended purpose is to
deliver the antibiotic, the product would be a medicinal product.
These principles are subject to certain exemptions as a consequence of which a number
of products fall within the definition of "medicinal product", even if they
fulfil their function by physical or chemical means, and not by pharmacological,
immunological or metabolic means in the sense as described above. This applies, in
particular, to antacids, in-vivo diagnostics, and to the products listed in A.4.2 which
are "administered to human beings with a view to making a medical diagnosis" or
to fulfil another purpose as indicated in the medicinal product definition. Unlike
products which, in the absence of Community medical device legislation, had been
assimilated to national medicinal product law and which are now regulated by MDD/AIMD
(reclassification will take place in those Member States during the transitional period),
the grouping as referred to in A.4.2 has been regarded throughout the EU as medicinal
products within the meaning of Directive 65/65/EEC. The status of these products as
medicinal products is retained as specified under A.4.2
A.3 Examples of medical devices
3.1 The following examples should, in view of their mode of action,
generally be considered as medical devices subject to relevant criteria being met; the
function of some of the devices indicated in these examples, e.g. bone cement, may be
assisted by the presence of medicinal substances where such substances have an ancillary
action to that of the device (see also A.5).
- bone cement (see A.5 and A.6),
- dental filling materials (see A.5 and A.6),
- materials for sealing, approximation, or adhesion of tissues (e.g. cyanocrylates,
fibrin-based adhesives not of human origin),
- resorbable materials used in osteo-synthesis (e.g. pins or bone screws manufactured
using polylactic acid),
- sutures, absorbable sutures,
- soft and hard tissue scaffolds and fillers (e.g. collagen, calcium phosphate,
bioglass),
- bone void fillers intended for the repair of bone defects where the primary action of
the device is a physical means or matrix, which provides a volume and a scaffold for
osteoconduction (see A5 and A6),
- intrauterine devices (see A.5 and A.6),
- blood bags (see A.5),
- systems intended to preserve and treat blood (see A5),
Note : systems intended for the collection, storage and preservation of blood or
blood components and as an ancillary function, the treatment of blood or blood components
where this effect is achieved outside the human body, are classified as devices provided
that any residual material is not intended to achieve its intended effect when the blood
or cells are reintroduced into the body, e.g. systems incorporating chemicals activated by
light to reduce the viral load where the quantity of chemical remaining has no intended
effect when transfused.
This note does not cover substances introduced into an extracorporal circuit.
- viscoelastic materials with intended use for mechanical/physical purposes such as
protection of tissues during and after surgery and separation of tissues. Such materials
are also used as synovial fluid replacements where visco-supplementation provides support
and lubrication.
Note : Additional pharmacological benefits claimed which are ancillary to the
mechanical action do not alter the medical device status. However, certain of these
materials such as some hyaluranon based products, where the predominant claims are of a
pharmacological nature and not primarily related to any viscoelastic characteristics, are
classed as medicinal products,
- gases and liquids for ocular endotamponades,
- cell separators, including those incorporating antibodies for cell marking,
- wound dressings, which may be in the form of liquids, gels and pastes, etc (e.g.
hydrocolloid, hydrogel), (see A.4 and A.5),
- haemostatic products, for example patches, plugs and powders where the
haemostatic effect results from the product's physical characteristics, or is due to the
surface properties of the material. This includes products such as those containing
collagen, or calcium alginate or oxidised cellulose where adhesion of
platelets to the surface triggers platelet adhesion and aggregation (see A.4 and A.5).
- concentrates for haemodialysis,
- pressure reducing valves and regulators,
- irrigation solutions (including those used in the eye) intended for pure mechanical
rinsing (see A5)
Note: If the solution contains a medicinal substance such as chlorhexidine where the
principal intended purpose is to provide a local antimicrobial effect, it will be a
medicinal product. Solutions incorporating substances for other purposes, e.g.
antimicrobial agent for the preservation of the solution remain a medical device.
- devices such as catheters, guidewires and stents containing or incorporating radio
isotopes where the radioactive isotope as such is not released into the body, used for
example in cardiology for the prevention of restenosis.
3.2 The following products are covered by the MDD because they
fall under the definition of "accessory". This is the case if they are intended
specifically to be used together with a device to enable the device to be used in
accordance with its intended purpose or to enhance the performance of the device.
- contact lens care products (disinfecting, cleaning, rinsing and hydrating solutions
including those which aid the insertion and/or wearing of contact lenses without a
therapeutic claim),
- disinfectants specifically intended for use with medical devices (e.g. endoscopes),
Note: Multipurpose disinfectants or sterilisation agents are not covered by MDD;
they will be covered by the directive on biocides.
- lubricants specifically intended for use together with medical devices (e.g. for
gloves, endoscopes, condoms),
- skin barrier powders and pastes or other skin care products specifically intended for
use together with ostomy bags,
- challenge tests specifically intended to assess the tolerance to a given medical
device, or its constituents (e.g. injectable collagen).
- gases used to drive cryoprobes and surgical tools (see A4)
A.4 Examples of medicinal products
The following examples should generally be considered as medicinal products subject to
relevant criteria being met :
4.1. Products which fulfil their primary intended purpose by pharmacological,
immunological or metabolic means,
- spermicidal preparations,
- gases intended to be used in anaesthesia and inhalation therapy, (e.g. Oxygen,
medical air supplied in containers) including their primary containers,
Note: These gases are also used in minimal access surgery. However a product intended
exclusively for minimal access surgery would be a medical device.
- topical disinfectants (antiseptics) for use on patients,
- haemostatic agents where primary mode of action is not mechanical such as certain
collagens which have a molecular structure capable of a surface-independent demonstrated
interaction with platelet receptors, and which achieves platelet adhesion through a
pharmacological process.
- zinc paste for dermatological use
4.2. Products which do not act by pharmacological, immunological or metabolic means,
but which are regulated in accordance with Directive 65/65/EEC as medicinal products.
- water for injections, IV fluids and plasma volume expanders,
- haemofiltration substitution solutions,
- in vivo diagnostic agents, e.g. x-ray contrast media, NMR enhancing agents,
fluorescent ophthalmic strips for diagnostic purposes, carrier solutions to stabilize
micro-bubbles for ultrasound imaging,
- gases for in-vivo diagnostic purposes, including lung function, tests, e.g. carbon
dioxide for vascular diagnostic purposes,
- solutions for peritoneal dialysis,
- antacids,
- artificial tears,
- fluoride dental preparations,
Note: Dental preparations with a typical device mode of action, such as cements
or varnishes incorporating fluoride, are medical devices, where the fluorine is of
ancillary action to that of the device. Certain products where the claims are primarily
cosmetic in nature and where the fluorine level is less than 0.15% are cosmetic products
(see 76/768/EEC and amending Directives).
- solutions administered in-vivo to the local circulation for the cooling of organs
during surgery;
It should be noted that the Directive 89/343/EEC relating to
radiopharmaceuticals applies also to generators, that means any system incorporating a
fixed parent radionuclide the daughter radionuclide of which is to be removed by elusion
or by any other method and used in a radiopharmaceutical (see article 1(2) of Directive
89/343/EEC).
4.3. Agents for transport, nutrition and storage of organs intended for
transplantation,
Note: These products are not currently regulated in all Member States as
medicinal products. However there was general consensus of public authorities that the
medicinal products category is the most appropriate. Some of these products may have a
metabolic effect, others however have no such effects.
A.5 Medical devices incorporating a medicinal substance with ancillary action
It follows from the definition of a medical device that devices may incorporate
substances as an integral part which, if used separately, may be considered to be a
medicinal product. This is specifically addressed in article 1(4) MDD which makes it clear
that such products are devices, provided that the action of the medicinal substance is
ancillary to that of the device, as reflected in the product claim and as supported by
the scientific data provided by the manufacturer of the devices.
Examples of such devices are:
- catheters coated with heparin or an antibiotic agent,
- bone cements containing antibiotic (see A.3 and A.6),
- root canal fillers which incorporate medicinal substances with secondary action (see
A.3 and A.6),
- blood bags containing anticoagulant or preservation agents (see A.3),
Note : rule18 of Annex IX of the MDD applies to these products.
- soft tissue fillers incorporating local anaesthetics,
- bone void filler intended for the repair of bone defects where the primary action of
the device is a physical means or matrix, which provides a volume and a scaffold for
osteoconduction and where an additional medicinal substance is incorporated to assist and
complement the action of the matrix by enhancing the growth of bone cells. In such cases,
the ancillary nature would be determined by the performance of the matrix on its own and
the extent of the enhancement of growth due to the presence of the substance. With
reference to the overall purpose of the product, where the medicinal substance has such an
effect that its ancillary nature cannot be clearly established, then the product should be
considered in accordance with the concept of a drug delivery system (see section A6.2),
- haemostatic devices enhanced by the incorporation of collagen, where the primary
action of the device is mechanical even though there may be ancillary action due to the
presence of collagen having demonstrable action with platelet receptors resulting in
platelet adhesion through a pharmacological process (see also A.3 and A.4),
- condoms coated with spermicides,
- electrodes with steroid-coated tip,
- wound dressings, surgical or barrier drapes (including tulle dressings) with
antimicrobial agent (see A.6),
- intrauterine contraceptives containing copper or silver,
- ophthalmic irrigation solutions principally intended for irrigation which contain
components which support the metabolism of the endothelial cells of the cornea (see A3).
It should be noted that the mere coating of a product with a chemical does not
imply that the chemical is a medicinal substance. For example, hydroxyapatite, frequently
used as coating for orthopaedic and dental implants, is not considered a medicinal
substance. Other coatings which are in use and which are not medicinal substances are
hydromers and phosphorylcholines.
Note : For the time being, products incorporating medicinal substances of human
origin are excluded from the MDD.
A.6 Drug delivery system
6.1. The status of devices for drug delivery is addressed by article 1(3) MDD. A device
which is intended to deliver a medicinal product is itself regulated as a medical device.
The medicinal product which the device is intended to administer must, of course, be
approved according to the normal procedures for medicinal products.
Examples :
- drug delivery pump,
- implantable infusion pump,
- iontophoresis device,
- nebulizer,
- syringe, jet injector.
Note: in a kit comprising an insulin pen and insulin cartridges, the pen is
subjected to the MDD whereas the insulin cartridge is a medicinal product.
- spacer devices for use with metered dose inhalers,
- port systems.
6.2. However, if the device and the medicinal product form a single integral product
which is intended exclusively for use in the given combination and which is not reusable,
that single product is regulated as a medicinal product (article 1(3), second subparagraph
MDD). Examples of such products are :
- prefilled syringes,
- aerosols containing a medicinal product,
- nebulizers precharged with a specific medicinal product, and not for universal
application,
- patches for transdermal drug delivery,
- implants containing medicinal products in a polymer matrix whose primary purpose is
to release the medicinal product, for example plastic beads containing antibiotic for
treating bone infections, or a matrix to release osteoinductive proteins into the
surrounding bone (see also A5)
- intrauterine contraceptives whose primary purpose is to release progestogens,
- single-use disposable iontophoresis devices incorporating a medicinal product,
- wound treatment products comprising a matrix whose primary purpose is the
administration of medicinal products, (see A.3 and A.5), for example wound dressings
containing an antimicrobial agent where the primary action of the dressing is to
administer the agent to the wound for the purpose of controlling infection,
- temporary root canal fillers incorporating medicinal products, whose primary
purpose is to deliver the medicinal product (see A.3 and A.5).
In such cases the essential requirements of the MDD apply as far as the device related
features of the product are concerned (for example as regards the mechanical safety
features of a prefilled syringe). The labelling, however, should comply with the
requirements of Directive 92/27/EEC applicable to medicinal products.
B. The consultation process for devices incorporating a
medicinal substance having ancillary action
B.1 Purpose of the consultation procedure
When referring to the appropriate essential requirement in the MDD - Annex 1, section
7.4 -, a Notified Body so concerned has a responsibility to address this requirement by
"consulting one of the competent bodies established by the Member States in
accordance with Directive 65/65/EEC before taking a decision (MDD: Annex II section 4.3
and Annex III section 5).
The term "Competent Authority" is used in this document to represent such a
competent body within the meaning of Directive 65/65/EEC, and indicates the authority
responsible for the evaluation of application for medicinal products being placed on the
market (see Annex for list of appropriate Competent Authorities).
In Essential Requirement 7.4 the expression "substance which, if used separately,
may be considered to be a medicinal product as defined in Article 1 of Directive
65/65/EEC..." is used. This reflects the fact that in such cases, neither the device
incorporating a medicinal substance nor the substance in itself is a medicinal product as
defined in Directive 65/65/EEC. This requirement relates to substances which, otherwise,
in the context of medicinal products may be an active constituent of a medicinal product
and therefore be liable to act upon the body.
It is for this reason that the verification by the Competent Authority of the safety,
quality and usefulness of the "medicinal substance" is to be carried out by
analogy with the appropriate methods specified in Directive 75/318/EEC as amended by
Directive 91/507/EEC.
The assessment of "usefulness" and "safety" has a particular
implication when applied to a medicinal substance which is of ancillary purpose within a
device/medicinal substance combination.
The aspect of "usefulness" relates to the rationale for using the medicinal
substance in relation to the specific intended purpose of the device. It refers to the
suitability of the medicinal substance to achieve its intended action, and whether the
potential inherent risks (aspects of "safety") due to the medicinal substance
are justified in relation to the benefit to be obtained within the intended purpose of the
device.
By means of the consultation process the competent authority may make available
relevant information concerning risks related to the use of the substance (e.g. resulting
from pharmacovigilance).
The ultimate responsibility for the decision, as to whether the pertinent legal
requirements are met, belongs to the Notified Body.
The consultation process is only applicable for devices incorporating a medicinal
substance as specified in Annex 1, section 7.4 and only where the substance is liable to
act upon the body with action ancillary to that of the device. Therefore, a contact lens
solution containing an antiseptic agent where the purpose of the antiseptic is to preserve
the solution does not fall under this procedure.
In line with Article 22(3) of the MDD, for a device which has already been granted a
marketing authorisation as a medicinal product in at least one member state the
consultation procedure will be limited to a simple exchange of letters between the
Notified Body and Competent Authority, provided the product is unchanged in all respects,
including the information provided with the device.
B.2 Notified Body actions to initiate consultation process
a) The Notified Body should ensure that data supplied by the manufacturer in relation
to the device and its intended use includes a specific segment regarding the medicinal
substance being incorporated with ancillary purpose. Presentation of the data according to
the format of the "Notice to Applicants" may facilitate the review by the
Competent Authority Ref:("The Rules governing medicinal products, volume 2B)
b) This segment should include data concerning the safety, usefulness and quality of
the medicinal substance, also appropriate details regarding information to be supplied
with the device when placed on the market to permit the evaluation of the aforementioned
features.
c) Before consulting a relevant Competent Authority the Notified Body should have come
to a preliminary opinion regarding the suitability of the device with ancillary medicinal
substance.
d) It is at the discretion of the Notified Body to choose the Competent Authority with
whom he consults from the listed Competent Authorities as indicated in the annex. The
European Medicines Evaluation Agency (EMEA) may be consulted, where the substance involved
has been included in a medicinal product which has been evaluated by the EMEA.
e) The Notified Body may consider it of benefit to utilise, for the consultation, the
appropriate Competent Authority previously responsible for a marketing authorisation for a
medicinal product which incorporates the medicinal substance involved in the consultation
process.
B.3 Documentation to be provided by the Notified Body to the competent
authority for medicinal products
Because of the wide range of medical devices which incorporate medicinal substances, a
flexible approach to the data requirements is necessary. Nevertheless the information
should be based in principle, to the extent relevant, on the annex to Directive
91/507/EEC, which modifies Directive 75/318/EEC, as outlined in (a) to (q) below. It is
envisaged that, where well-known medicinal substances for established purposes are
involved, all aspects of safety and usefulness may not be required and many of the
headings will be addressed by reference to the literature, including standard textbooks,
experience and other information generally available. Nonetheless all headings should be
addressed.
For new active substances and for known medicinal substances in a non-established
purpose, comprehensive data is required to address items (a) to (q) below. The evaluation
of such active substances would be performed in accordance with the principles of
evaluation of new active substances. The principal headings of Directive 91/507/EEC are
given below, together with comments on their applicability to medical devices. This
represents a comprehensive checklist covering headings which may be appropriate depending
on the circumstances relating to the case in question.
a) General information
A general description of the medical device including
the manufacturer's claim regarding the purpose of the inclusion of the substance, together
with a critical appraisal of the results of the risk analysis.
b) Qualitative and quantitative
particulars of the constituents
A description of the substance and the amount (giving
a range where appropriate) of the medicinal substance incorporated into each medical
device. If the substance is modified during its incorporation into the device, relevant
information shall be provided.
c) Description of method of
manufacture
An overall description will already form part of the
application to the Notified Body; the section dealing with incorporation of the medicinal
substance in the device should be provided.
d) Controls of starting materials
The specification for the medicinal substance shall be
provided. Where applicable, reference shall be to the European Pharmacopoeia or in the
absence of an EP monograph to a national pharmacopoeia of one of the Member States. If no
monograph is available from the Member States reference may be to other national
monographs or to the manufacturer's specification and methods of analysis.
For new active substances and certain known substances additional information will be
required which may be provided in the form of a Drug Master File. The guideline
"Requirements in relation to active substances" may be of assistance in
providing circumstances where reference to a Pharmacopoeia monograph may need to be
supplemented by further information.
e) Control tests carried out at intermediate stages of the manufacturing process of the
medical device
This information is only necessary if it is directly relevant to the quality of the
substance as incorporated in the medical device.
f) Control tests on finished product
Qualitative and quantitative tests carried out to
control the medicinal substance in the device.
g) Stability
Information defined to show the medicinal substance
maintains its desired function throughout the defined shelf-life of the device, taking
account of the manufacturer's recommended storage conditions.
h) Toxicity
Reference to the known toxicological profile of the
medicinal substance may be provided. In the case of new active substances, the results of
toxicity tests, should be supplied. This may include information on toxicity and
biocompatibility of the medical device which may be available from evaluation in
accordance with the EN 30993 series of standards.
i) Reproductive function
Similar considerations to h) apply.
j) Embryo/foetal and perinatal toxicity
Similar considerations to (h) apply.
k) Mutagenic potential
Similar considerations to h) apply.
l) Carcinogenic potential
Similar considerations to h) apply. The need for data
on carcinogenicity should be addressed taking account of available information on the
medicinal substance, the results of genotoxicity testing, the chemical structure of the
medicinal substance, and the duration of potential exposure to the substance.
m) Pharmacodynamics
This section should address the intended action of the
medicinal substance in the context of its incorporation into a medical device.
n) Pharmacokinetics
It is anticipated that pharmacokinetic studies will not be required in the majority
of cases. Some or all of the following areas may need to be addressed as appropriate:
- description of the pattern of local and systemic exposure to the medicinal substance,
- where the level of exposure fluctuates, the maximum level and duration of exposure
should be considered,
- where it is considered possible that potential levels of systemic exposure may
present a safety concern, maximum peak plasma concentration should be established, taking
due consideration of individual variability,
- new active substances will require information on the release from the device, and,
if relevant, its subsequent distribution and elimination.
o) Local tolerance
This is of particular relevance since the route of
exposure to the medicinal substance may be different from its conventional application.
The relevant results of device testing according to EN 30993 should be provided or, where
appropriate, information from the scientific literature
p) Clinical documentation
Since the devices will normally be class III, clinical
data will form part of the information provided to the Notified Body under annex II or
III. This data will address the safety of the device in its entirety. The usefulness of
the medicinal substance in the medical device should be addressed by clinical data or in
other sections of the dossier.
An appropriate methodology for clinical investigations on medical devices is described
in EN 540.
q) Labelling
Details supplied by the manufacturer of labelling or
information to be provided with the device with regard to the medicinal substance, is to
be supplied to the Competent Authority to assist in the understanding of the safety and
usefulness of the substance together with the device.
B.4 The consultation process
a) The Notified Body, having requested a Competent Authority to provide an opinion
concerning the medicinal substance and its application, should, together with the
Competent Authority, agree such matters as: time-schedules, modalities to obtain further
information, including clock stops, fees and practical arrangements for
submission of data.
b) The Notified Body should make available to the Competent Authority relevant data as
specified in B.3.
c) The Competent Authority should verify the data provided by the Notified Body. It
should consider the use of the medicinal substance by analogy with existing information
regarding the known applications and appropriate features of safety, quality and
usefulness as they may be relevant to the specific intended purpose of the device
incorporating the medicinal substance.
d) The Competent Authority should inform the Notified Body of its conclusions and
advice as to the suitability of the medicinal substance in its proposed use.
e) The Notified Body should take into account the opinion of the Competent Authority
and use its judgement to either approve the drug/device combination, after consideration
of all aspects of risk/benefit in the intended or expected use of the product, or
alternatively to reject the product. It may be that certain suggestions from the Competent
