COMMUNICATION FROM THE COMMISSION

Guideline on the format and content of applications for agreement or modification of a paediatric investigation plan and requests for waivers or deferrals and concerning the operation of the compliance check and on criteria for assessing significant studies

(Text with EEA relevance)

2014/C 338/01

1.   INTRODUCTION

1.1.   Scope

This guideline, which replaces the previous version from 2008 (1), sets out:

1.2.   Definitions

For the purposes of this guideline, the following definitions apply:

(a)   condition: any deviation from the normal structure or function of the body, as manifested by a characteristic set of signs and symptoms, typically a recognised distinct disease or a syndrome;

(b)   paediatric investigation plan indication: proposed indication in the paediatric population for the purpose of a PIP, and at the time of submission of the PIP, within a specific condition;

(c)   proposed indication: the indication for use in adults as proposed by an applicant at the time of submission of the PIP/waiver application. In cases of a completed or ongoing adult development, this is the starting point for identifying the condition for potential paediatric use;

(d)   measure: any study or other obligation (for example, a requirement to set up a registry), which is included in the PIP, with a view to ensuring that, in accordance with Article 15(2) of the Paediatric Regulation, the necessary data are generated to demonstrate the quality, safety and efficacy of the medicinal product in the paediatric population;

(e)   study: any measure that is designed to answer a specific scientific question, and is performed in accordance with a predefined methodology. This includes, for example, interventional and non-interventional studies, non-clinical studies, extrapolation studies, modelling and simulation studies, development of specific paediatric pharmaceutical forms and formulations;

(f)   extrapolation study: a study involving the use of extrapolation to support the use of the medicinal product in children (3). An extrapolation study may be based on case series, meta-analyses, systematic reviews and modelling and simulation studies;

(g)   modelling and simulation study: a study with the objective of quantifying the medicine/system/experimental design, in order to:

(h)   key elements: each measure in a PIP may contain one or more specific key elements, as specified in the annex to this guideline; key elements are binding and provide the basis for the operation of the compliance check.

2.   FORMAT AND CONTENT OF APPLICATIONS FOR AGREEMENT ON OR MODIFICATION OF A PAEDIATRIC INVESTIGATION PLAN AND REQUESTS FOR WAIVERS AND DEFERRALS

2.1.   General principles and format

2.1.1.   Structure of application

Applications for agreement on or modification of a PIP or requests for waiver or deferral and combinations thereof should be accompanied by particulars and documents in accordance with this guideline. Applications should consist of the following sections:

Part A: Administrative and product information

Part B: Overall development of the medicinal product

Part C: Application for a product-specific waiver

Part D: Proposed paediatric investigation plan

Part E: Request for deferral

Part F: Annexes

Sections and/or subsections that are not relevant for the specific application can be left empty.

The European Medicines Agency (hereinafter ‘the Agency’) publishes templates and online forms based on this guideline. In addition, procedural advice is available on the Agency’s website (www.ema.europa.eu).

2.1.2.   Supporting information

The application should be based on all available information relevant to the evaluation, whether favourable or unfavourable to the product and its development. This includes details of any incomplete or discontinued pharmaco-toxicological test or clinical trials or other studies relating to the medicinal product, and/or completed trials concerning indications not covered by the application.

The amount of available information relevant to applications will differ substantially, depending on whether a medicinal product is in early clinical development or already authorised, and is being investigated for new or extended uses. Therefore, the level of detail expected in the application may differ significantly in line with the specific development stage of the product when the application is submitted.

2.1.3.   Paediatric population

Applications subject to the requirements of Article 7 or 8 of the Paediatric Regulation should cover all subsets of the paediatric population (4) unless there are grounds for a waiver. The paediatric population encompasses several subsets, as defined e.g. in international guidelines (5):

However, when it is considered more appropriate to use different subsets (e.g. based on gender or stage of pubertal development), this may be acceptable, but the choice of subsets should be explained and justified.

A PIP application intended to support a future paediatric use marketing authorisation (PUMA) may be limited to certain paediatric subsets; it is not required to address all subsets.

2.1.4.   Coverage of application

A single application should cover the proposed research and development programme for a future single marketing authorisation application. Where the product is developed in stages and for different conditions, the applicant may apply for separate PIPs. Applications for authorised products which will fall within the scope of Article 8 of the Paediatric Regulation should cover all existing and new indications, pharmaceutical forms and routes of administration with a view to agreement on a single comprehensive PIP.

The application may include a request for a product-specific waiver. Additionally, a PIP may include a request for deferring some or all of the measures.

2.1.5.   Preparing the application

Applicants are advised to request a pre-submission meeting to discuss the timing of submission of the application and to facilitate successful validation and assessment.

Applicants are encouraged to consult the paediatric research community, for example via the European networks for paediatric research at the Agency, as early involvement may facilitate the development of a PIP.

2.2.   Part A: Administrative and product information

All sections of Part A should be completed; where information is not available, this should be stated. Part A information should be submitted using the form published by the Agency.

2.2.1.   Name or corporate name and address of the applicant and contact person

The name and address of the applicant should be provided, together with the contact details of the person authorised to communicate with the Agency on behalf of the applicant.

As Agency decisions will be made public, the applicant is encouraged to provide a contact point (telephone number and/or e-mail address) for enquiries from interested parties. The Agency will make this public with its decisions. Personal e-mail addresses should be avoided.

Where the applicant qualifies as a micro, small or medium-sized enterprise within the meaning of Commission Recommendation 2003/361/EC (6), this should be stated.

2.2.2.   Name of the active substance

The active substance should be stated by its recommended international non-proprietary name (INN), accompanied by its salt or hydrate form if relevant. If no ‘recommended’ INN exists, the European Pharmacopoeia name should be provided or, if the substance is not in the European Pharmacopoeia, the usual common name should be used. In the absence of a common name, the exact scientific designation should be given. Substances without an exact scientific designation should be described by a statement of how and from what they were prepared, supplemented where appropriate by any relevant details.

In addition to the common name or scientific designation, the applicant may also submit the company or laboratory code.

Preliminary names only may be provided if necessary in view of the deadline for submission of the applications.

2.2.3.   Type of product

The type of product for which the application is made (e.g. a chemical entity, a biological product, a vaccine, a gene therapy product, a somatic cell therapy medicinal product) should be specified. In addition, the pharmacological target and mechanism of action should be specified where possible. Where a pharmaco-therapeutic group and anatomical therapeutic chemical (ATC) code have been assigned, these should be included.

2.2.4.   Details of the medicinal product

Information on all different pharmaceutical forms, formulations, strengths and routes of administration under development, irrespective of future use in the paediatric population, should be provided. For the paediatric product development, information on the proposed strength, pharmaceutical form, route of administration and formulation (including details on the proposed excipients) should be provided.

2.2.5.   Marketing authorisation status of the medicinal product

Information on the marketing authorisation status of the medicinal product should be provided in tabular format.

For medicinal products authorised in the EU, the marketing authorisation status, including information on all authorised indications, strengths, pharmaceutical forms and routes of administration, should be provided and, as regards authorisation status outside the EU, only information on authorisations in children should be included.

For products being developed for PUMAs, information should be provided on medicinal products authorised in the EU that contain the same active substance.

For medicinal products not yet authorised in the EU, the marketing authorisation status in adults and children outside the EU should be provided.

Details should be provided of any regulatory measures restricting for safety reasons the use of the medicinal product inside or outside the EU. This includes the suspension, revocation or non-renewal of the marketing authorisation, prohibition on supply, withdrawal of the medicinal product, a new contra-indication, a reduction in the recommended dose or a restriction on the indications of the medicinal product.

2.2.6.   Advice from a regulatory authority relevant to development in the paediatric population

The Agency should be provided with any decisions, opinions or advice (including scientific advice) given by competent authorities, including those in non-EU countries, on the paediatric development of the medicinal product. This should include any written request for paediatric information issued by a regulatory body. Copies of any relevant documents should be annexed to the application.

2.2.7.   Orphan medicine status in the EU

For orphan-designated products, the European Union Register of Orphan Medicinal Products number should be provided. If orphan designation is being sought, this should be indicated, and for pending applications the Agency’s Orphan Designation Procedure number should be provided.

2.2.8.   Planned application for marketing authorisation/extension of marketing authorisation/variation

The planned submission date for the marketing authorisation (or next variation/extension application under Article 8 of the Paediatric Regulation, as appropriate) should be provided, together with an indication of whether the intention is to submit the application via the centralised procedure or the procedures provided for by Directive 2001/83/EC (7).

For medicinal products not yet authorised which will fall under the requirements of Article 7 of the Paediatric Regulation, the planned or confirmed date of completion of the adult pharmaco-kinetic studies should be provided. Where an application is submitted more than six months after completion of such studies, a justification should be provided in this section.

2.2.9.   Application summary

Applications for PIPs or waivers should be accompanied by an application summary of no longer than 1 000 words written in accordance with a template published by the Agency.

2.2.10.   Translations of the Agency decision

If the Agency decision is requested in an official EU language other than English, the name of the active substance, the condition, the pharmaceutical form and route of administration should be provided in that language.

2.3.   Part B: Overall development of the medicinal product

Part B should set out, for each existing indication and proposed condition/indication, and each subset of the paediatric population, how the requirements of the Paediatric Regulation will be met.

Where the medicinal product is developed for use in children only, some of the information requested in Part B may not be available. For products being developed for PUMAs, only the concerned paediatric subsets need to be addressed.

Applicants should provide:

The following points should be taking into account in the description of the condition. These points address, in particular, what constitutes a valid condition, as opposed to what would be considered as invalid subsets within a condition and how these elements are linked to existing treatments and to the proposed indication:

2.3.1.   Discussion of similarities and differences in the condition between populations, and pharmacological rationale

The application should briefly discuss any potential differences or similarities within the condition between the adult and the paediatric populations and/or between the different paediatric subsets.

These should be discussed with a view to extrapolating efficacy and/or pharmaco-kinetics, between adults and children, and the various paediatric subsets. Differences in aetiology, severity, symptoms, evolution, prognosis and response to therapy should be addressed where applicable.

Additionally, applicants should provide:

2.3.2.   Current methods of diagnosis, prevention or treatment in paediatric populations

For each condition covered by the application, the diagnosis, prevention and treatment interventions that are available in the EU should be identified, making reference to scientific literature or other relevant information. This should include unauthorised treatment methods, whether pharmacological, surgical, dietary or otherwise, if they represent the standard of care (e.g. if mentioned in internationally recognised treatment guidelines). This should be presented in tabular format.

In the case of authorised medicinal products, the list of available treatments identified should include those authorised by the national authorities and those authorised under the centralised procedure. This can be presented as an overview table. Information on generic medicinal products need not be provided if the reference medicinal product is identified.

For medical devices marketed in the EU, the invented name and the approved use should be provided.

If methods for diagnosis, prevention or treatment of the condition in question have been included in the inventory of therapeutic needs established pursuant to Article 43 of the Paediatric Regulation, this information should be highlighted.

2.3.3.   Significant therapeutic benefit and/or fulfilment of therapeutic need

The Paediatric Committee will assess whether the specific medicinal product is expected to be of significant therapeutic benefit to children and/or to fulfil a therapeutic need in children. The application should include a comparison of the medicinal product in question with the current methods of diagnosis, prevention or treatment of the conditions that are the subject of the PIP indication.

When assessing significant therapeutic benefit, the Paediatric Committee will take into account the nature and seriousness of the paediatric condition to be treated (or diagnosed or prevented) and available data on the medicinal product concerned. Significant therapeutic benefit could be based on one or more of the following:

As experience with the use of the medicinal product in the paediatric population might be unavailable or very limited at the time of submission of the application, significant therapeutic benefit could also be based on well-justified assumptions. The application should explore these assumptions on the basis of reasoned arguments and relevant literature.

If the therapeutic need is included in the inventory of therapeutic needs pursuant to Article 43 of the Paediatric Regulation, the application should refer to the inventory.

2.4.   Part C: Applications for product-specific waivers

2.4.1.   Overview of the waiver request

A waiver may be issued with reference either to one or more specified subsets of the paediatric population, or to one or more specified indications/conditions, or to a combination of both. Requests for product-specific waivers should clearly define their scope in terms of paediatric subset and indication.

A product-specific waiver will not be required if the product and the proposed indication are already covered by a class waiver.

Companies are advised to ask the Agency to give advance confirmation of the applicability of a class waiver to a proposed development of a medicinal product in one or more adult conditions.

If applicants intend to claim that measures in the paediatric population are not feasible, appropriate and detailed justification should be provided to support the claim.

2.4.2.   Justification for a product-specific waiver

2.4.2.1.   Applications based on a likely lack of safety or efficacy in part or all of the paediatric population

In accordance with Article 11(1)(a) of the Paediatric Regulation, a waiver may be granted if ‘the specific medicinal product or class of medicinal products is likely to be ineffective or unsafe in part or all of the paediatric population’. On this basis, a request for a waiver may be based on a pharmaceutical rationale or (preliminary) data suggesting lack of efficacy or safety in the paediatric population.

The application should take account, for the different paediatric subsets, of the seriousness of the condition and the availability of other methods as stated in Part B. All available evidence should be submitted to illustrate the likely lack of efficacy in the paediatric population as a whole or in subsets, as applicable. The justification should be based on effects observed in non-clinical models and studies, where available, or on a review of scientific literature.

The justification for a waiver based on the likelihood or evidence that the product is likely to cause harm may differ depending on experience with the product. Justification for a waiver on these grounds may include the pharmacological properties of the product or class of product, results of non-clinical studies, clinical trials or post-marketing data. The applicant should signal specific known or suspected safety issues.

The absence of available data on the safety or efficacy in the paediatric population will not be accepted as the sole justification for a waiver.

2.4.2.2.   Applications based on the disease or condition not occurring in the specified paediatric subset

In accordance with Article 11(1)(b) of the Paediatric Regulation, a waiver may be granted if ‘the disease or condition for which the specific medicinal product or class is intended occurs only in adult populations’. On this basis, a justification for a waiver may be based on a detailed description of the incidence or prevalence of the condition in different populations. For waivers covering the totality of the paediatric population, the justification should focus particularly on the earliest age of onset of the condition. For waivers for specific subsets of the paediatric population, the justification should focus on the incidence or prevalence in the paediatric subsets identified in Part B.

2.4.2.3.   Applications based on lack of significant therapeutic benefit

In accordance with Article 11(1)(c) of the Paediatric Regulation, a waiver may be granted if ‘the specific medicinal product does not represent a significant therapeutic benefit over existing treatments for paediatric patients’. On this basis, the justification for a waiver may be based on a lack of significant therapeutic benefit.

Justification for such a waiver should be based on a detailed discussion of the existing treatment methods. Reference can be made to the discussion under point 2.3.3.

In particular, where existing medicinal products are authorised for use in children, applicants intending to request a waiver on this ground should justify in detail why the new product would lack significant benefit over the existing treatments.

2.5.   Part D: Proposed paediatric investigation plan

Part D should focus on the development of the medicinal product for the paediatric population. While applicants can discuss possible choices, there is no need to propose separate alternative developments in the application.

2.5.1.   Existing data and overall strategy proposed for the paediatric development

2.5.1.1.   Paediatric investigation plan indication

The PIP indication should be described for the paediatric subsets included in the paediatric investigation plan. This part should specify whether the medicinal product is intended for the diagnosis, prevention or treatment of the conditions in question.

2.5.1.2.   Selected paediatric subsets

The age ranges to be studied should be justified, and may vary depending on the pharmacology of the product, the manifestation of the condition in various age groups and other factors. In addition to age, the classification of the paediatric population may be based on other variables, such as gestational age, pubertal stages, gender and renal function.

2.5.1.3.   Information on quality, non-clinical and clinical data

The application should outline the development of the medicinal product, including the pharmaceutical development which is relevant for paediatric development, completed clinical studies in adults and the results where available. A brief outline of the planned studies in adults should also be provided. This information may be provided in tabular format.

The full study reports of completed non-clinical and clinical studies do not need to be provided; a summary of the results and a discussion of the implications for paediatric development should be sufficient. Full reports should be made available upon request. The application should take into account any existing scientific guidance/advice and standard PIP published by the Agency and justify any deviation for the paediatric development.

In addition, the application should include a review of any information on the product in the paediatric population, making reference to scientific and medical literature or other relevant information, such as reports on use outside the terms of a marketing authorisation, medication errors, accidental exposures or known class effects.

2.5.2.   Paediatric formulation development

2.5.2.1.   General strategy

This section should address selected aspects related to the administration of the product to the relevant paediatric subsets.

Guidelines on pharmaceutical development should be consulted to decide which measures could be relevant within the proposed strategy (8).

The addition of a paediatric indication may result in the need for an age-appropriate pharmaceutical form, e.g. a dispersible form rather than a large tablet, or a mini-tablet of a new strength, because the existing pharmaceutical form, excipients or strength may be unsuitable for use in all or part of the relevant paediatric populations. This means that the suitability of the existing formulation, strength and pharmaceutical form should be discussed in the PIP. Consideration may be given to ethnic or cultural differences as regards acceptability, route of administration, acceptable dosage forms and excipients, in relation to the specific characteristics of the product.

The discussion should take into account the existing or proposed pharmaceutical development of the product and address critical issues, such as:

If it is not possible, based on scientific justifications, to develop a formulation/pharmaceutical form which is relevant and acceptable for paediatric use on an industrial scale, the applicant should state how it intends to facilitate the industry-verified or extemporaneous preparation of an individual ready-for-use paediatric formulation.

2.5.2.2.   Summary of all planned and/or ongoing measures in the pharmaceutical development

The application should contain in tabular form a list of planned and/or ongoing measures and studies intended to address the issues discussed under point 2.5.2.1. This should consist of the proposed key elements, as relevant and in accordance with the annex to this guideline, and be submitted using the specific form published by the Agency.

If the strategy is to create age-appropriate pharmaceutical form, formulation, strength or new route of administration, the necessary pharmaceutical development studies may need to be more extensive. Proposed measures of particular relevance to the development of paediatric products include:

2.5.3.   Non-clinical studies

2.5.3.1.   General strategy

This section should discuss the strategy for the non-clinical development which is needed to support paediatric use in addition to classical non-clinical development or existing data. If human safety data and previous animal studies are considered insufficient for reassurance on the likely safety profile in the intended paediatric age group, juvenile animal studies should be considered on an individual basis.

Reference to guidelines on non-clinical development should be made as necessary when discussing non-clinical studies.

The standard non-clinical development should not be submitted or discussed unless it adds relevant information to the paediatric development and is not covered elsewhere (e.g. the annexed investigator’s brochure).

The following aspects should be discussed, taking into consideration existing scientific guidance:

2.5.3.2.   Summary of all planned and/or ongoing non-clinical studies

A tabular list should be provided, with the proposed non-clinical studies. This should consist of the proposed key elements for the non-clinical studies, as relevant and in accordance with the annex to this guideline, and should be submitted using the specific form published by the Agency.

2.5.4.   Paediatric clinical studies

2.5.4.1.   General strategy

This section should discuss and justify the strategy for the clinical paediatric development, in relation to the development in adults where applicable and in relation to existing data and the potential to extrapolate. This should include only critical aspects of study design and should present the strengths, advantages and disadvantages of the proposed clinical development. Where appropriate, the extension of adult trials to paediatric patients (e.g. adolescents) may be considered.

In this section, the application should also:

Trials should be performed in the least vulnerable groups whenever possible (i.e. in adults rather than in children, in older rather than younger children). If results cannot be extrapolated to younger groups, this should be justified.

2.5.4.2.   Paediatric pharmaco-kinetic/pharmaco-dynamic studies

The following aspects should be considered, where relevant:

2.5.4.3.   Clinical efficacy and safety studies

The following aspects should be discussed, where relevant:

2.5.4.4.   Summary of all planned and/or ongoing paediatric clinical studies

A tabular list should be provided, with the proposed clinical studies. This should consist of the proposed key elements for clinical studies, as relevant and in accordance with the annex to this guideline, and be submitted using the specific form published by the Agency.

The table should propose timelines for the initiation and completion of each study, including either specific dates (month and year) or ranges of up to six months, and specify whether a deferral is being requested for the initiation and/or completion of each measure. Alternatively, timelines for initiation may be linked to the completion of a study in adults (‘x months after completion of study y’) or a measure in the PIP.

Clinical studies are deemed to have been completed on the date of the last visit of the last subject in the study or at a later point in time as defined in the protocol. It is advisable that the dates proposed in the table take account of the time needed to complete, analyse and report the studies to the competent authorities.

2.5.4.5.   Details of the planned and/or ongoing paediatric clinical studies

To facilitate the scrutiny of the proposed development programme, the applicant may, in addition to the proposed key elements, provide more detailed information, such as a synopsis of the study protocol (or the full protocol if available).

Further information, if available and as appropriate to the stage of product development, should be provided on the following:

2.5.5.   Other studies

If extrapolation and/or modelling and simulation studies are part of the proposed PIP, a tabular list with the proposed studies should be provided. This should consist of the proposed key elements, as relevant and in accordance with the annex to this guideline, and be submitted using the form published by the Agency.

Those other studies are deemed to have been completed on completion of the relevant study report.

2.6.   Part E: Request for deferral

Where it is not planned that a study or other measure in the PIP will be initiated or completed before the submission of the corresponding marketing authorisation application in adults, a deferral may be requested. Requests for deferral should be justified on scientific and technical grounds or on grounds related to public health.

In accordance with the Paediatric Regulation a deferral will be granted when:

With reference to the timelines in Part D, any request for deferral of the start or completion of studies or other measures should make clear to which study/measure the deferred timeline relates.

For timelines, either specific months and years should be given or a range of up to six months; timelines for initiation may also be expressed in relation to the development in adults.

Particular emphasis should be placed on the timing of the measures as compared with the development for adults, e.g. as expressed in the ICH guideline E11.

2.7.   Part F: Annexes

The annexes to the application should include the following, if available:

2.8.   Modification of an agreed paediatric investigation plan

Article 22 of the Paediatric Regulation provides for an agreed plan to be modified where necessary. Such modifications are required where key elements of the PIP are unworkable or no longer appropriate. A request for modification of an agreed PIP is not necessary if the modification affects only aspects of a study or a measure that are not reflected in any agreed key element.

Applicants should explain the lack of appropriateness or the feasibility issue underlying each key element for which modification is being requested and discuss whether this should be addressed by a modification, a deferral or a waiver. An assessment of the effect of both making and failing to make the proposed change should be provided.

Submission of an application to modify the PIP will be particularly important if new information may have an impact on the nature or timelines for completion of one of the key elements in the Agency decision on the PIP.

Applications for modification should follow the same structure as initial applications, but only sections relevant to the change should be completed. Applications should be accompanied by an application summary of no longer than 500 words.

3.   OPERATION OF THE COMPLIANCE CHECK

In accordance with Articles 23 and 24 of the Paediatric Regulation, compliance with the agreed PIP is checked at various stages by the competent national authorities or the Agency:

The compliance check prior to or upon validation of a marketing authorisation application is of particular importance. Article 23 provides that the Paediatric Committee may on request issue an opinion on compliance and clarifies who can request such an opinion and when. For example, the Agency or the competent national authorities may request an opinion when validating an application. Under the second subparagraph of Article 23(3), Member States must take account of the opinion of the Paediatric Committee.

The compliance checks will determine whether:

The studies or other measures checked for compliance are those that are part of the condition covering an indication for which an application for marketing authorisation is made and that were to have been completed at the time of the submission. Where the scope of the application is exceptionally covered by more than one PIP, all concerned PIPs will be checked for compliance.

Any necessary modification of the PIP should take place before the submission of the application for marketing authorisation or variation.

To facilitate the work of the competent authorities and, where appropriate, the Paediatric Committee in reaching an opinion on compliance, applicants are encouraged to present a compliance report when submitting the application for marketing authorisation, extension or variation. Additionally, for nationally authorised products, applicants should submit the latest complete Agency decision (which includes the opinion with the key elements, and the summary report) to the competent national authorities concerned.

For medicinal products that fall under the scope of Articles 7 or 8, the compliance report should indicate in the form of a table how each subset of the paediatric population and, for applications falling under Article 8, how each of the existing and new indications, pharmaceutical forms and routes of administration have been covered by the documents referred to in Article 7(1).

A separate table should be included covering the applicant’s position on compliance with the key elements and, where submitted with the marketing authorisation application, providing a cross-reference for each key element of the PIP to the location in the relevant module in the marketing authorisation application. If a PIP has been modified, the table should be based on the latest decision by the Agency.

It should be noted that:

When only some measures referred to in the Agency decision were to have been completed at the time of submission of the application, the Agency or the Paediatric Committee will provide the applicant with a letter confirming the compliance or otherwise of those measures. Where compliance is not confirmed, the grounds will be detailed in a report.

The compliance check under Article 23 is without prejudice to the possibility that the competent authority will conclude, when conducting the scientific assessment of a valid application, that the studies are in fact not in conformity with the agreed PIP.

The statement of compliance should be included in the marketing authorisation. This may be done by including it with other technical information forming part of the marketing authorisation (‘technical dossier’), in which case the competent national authorities, or the Agency in the case of variations or extensions of centralised marketing authorisations, must confirm to the marketing authorisation holder that this has been done.

Where the measures in a PIP contain no study initiated before the entry into force of the Paediatric Regulation (i.e. 26 January 2007), the statement of compliance referred to in Article 28(3) will read as follows:

Where the measures in a PIP contain some studies initiated before the entry into force of the Paediatric Regulation, the statement of compliance will read as follows:

4.   CRITERIA FOR ASSESSING THE SIGNIFICANCE OF STUDIES PURSUANT TO ARTICLE 45(3) OF THE PAEDIATRIC REGULATION

4.1.   Background

To qualify for the reward and incentives provided for in Articles 36, 37 and 38 of the Paediatric Regulation, PIPs which include studies initiated and/or completed before its entry into force must include ‘significant’ studies that were initiated and/or completed after that date (see Article 45(3)). The statement of compliance referred to in Article 28(3) of the Regulation will indicate whether the studies are considered ‘significant’ within the meaning of Article 45(3).

A study will be considered as having been completed after the entry into force of the Regulation if the date of the last visit of the last patient is after that date. Open extensions of studies consisting of treatment maintenance for patients will not be considered as continuing after the entry into force if this was not part of the protocol submitted to the relevant competent authorities.

4.2.   Assessment criteria

In general, the significance of studies is determined by the clinical relevance of data generated for the paediatric population rather than by the number of studies. In exceptional cases, a set of non-significant studies might be considered significant if the results taken together are expected to provide important and clinically relevant information.

The Agency or the competent authorities will assess the significance of each study proposed in a PIP on a case-by-case basis. However, the examples below are provided as a guide to the assessment of the significance of studies.

The following study types will generally be considered as significant:

In order to be considered significant, studies should normally cover several paediatric subsets, unless a waiver has been granted. However, studies conducted in a single subset of the paediatric population could be considered significant if:

Where sufficient data for one or more of the paediatric subsets are already available, duplication of studies should be avoided and unnecessary studies will not be considered significant.
