虽然临床证据是上市前符合性评定程序的基本要素,但重要的是要认识到,这些上市前临床调查存在局限性。

虽然在上市前阶段已经收集了广泛的数据,但是并不能保证制造商能够察觉到不常见的并发症或问题,而这些问题只有在医疗器械被大范围的使用和长期运行后才会显现。

作为医疗器械制造商的质量体系,或上市后监督体系的一个部分,关键就是需识别和调查销售后的医疗器械在使用过程中所具有的风险。

制造商应建立上市后监督系统,并且对每一个产品或产品类都应有明确的PMS(上市后监督)策划。

因此,选择PMCF(上市后临床跟踪)看起来是实现此目的的一个方法。

通过建立一个长期的安全跟踪评审程序和侦查一些可能出现的风险,它可以使病人获得新的疗法,而这些风险仅仅依赖上市前的临床调查(仅仅要求相对很短的时间跟踪)和根据产品经验或产品警惕性都是不能完全充分地察觉到的。

They are legally not binding. The Guidelines have been carefully draftedthrough a process of intensive consultation of the various interest parties (competent authorities,Commission services, industries, other interested parties) during which intermediate drafts wherecirculated and comments were taken up in the document.

They are adapted to the requirements on clinical investigations laid out in annex 7 of directive 90/385/EEC and in annex X of directive 93/42/EEC as amended by directive 2007/47/EC. The clinical investigations shall be performed as described in these annexes.They reflect the consensus view of the various interested parties with regard to clinical investigations under the above-mentioned medical devices directives.What is a clinical investigation?A clinical investigation is defined as “any systematic investigation or study in or on one or more human subjects, undertaken to assess the safety and/or performance of a medical device.” (SG5/N1:2007).The undertaking of a clinical investigation is a scientific process that represents one method of generating clinical data.What is the objective of a clinical investigation?The objective of a clinical investigation is to assess the safety and clinical performance of the device in question and evaluate whether the device is suitable for the purpose(s) and the population(s) for which it is intended (EN ISO 14155-1:2009).How is a clinical investigation conducted?EN ISO 14155-1:2009 Clinical Investigation of Medical Devices for Human Subjects - General Requirements details the general requirements for the conduct of clinical investigations and EN ISO 14155-2:2009 Clinical Investigation of Medical Devices for Human Subjects - Clinical Investigation Plan contains detailed information about the procedure and contents of a clinical investigation plan. Clinical investigations must take into account scientific principles underlying the collection of clinical data along with accepted ethical standards surrounding the use of human subjects. The clinical investigation objectives and design should be documented in a clinical investigation plan.2 ScopeThe primary purpose of this document is to provide guidance in relation to:• when a clinical investigation should be undertaken for a medical device to demonstrate compliance with the relevant Essential Requirements; and• the general principles of clinical investigations involving medical devices.Given the wide diversity of medical devices and their associated risks, this document is not intended to provide comprehensive guidance for clinical investigations of specific medical devices.The guidance contained within this document is intended to apply to medical devices generally and to combination products regulated as medical devices. It is not intended to cover in vitro diagnostic medical devices. Additionally, this document was drafted primarily to address the use of Clinical Investigations to support clinical evaluation and a conformity assessment procedure. Some aspects of this document may apply to studies conducted following commercial release of a device. A separate guidance document specifically addresses post-market clinical follow-up (MEDDEV 2.12/2: Clinical Evaluation - Post Market Clinical Follow-up).3 ReferencesDirective 90/385/EEC, as amended by Directive 2007/47/ECDirective 93/42/EEC, as amended by Directive 2007/47/ECInterpretative DocumentsMEDDEV 2.7.1 Rev. 3; December 2009Clinical Evaluation: A Guide for Manufacturers and NotifiedBodiesMEDDEV 2.7.1, Appendix 1; December 2008Evaluation of Clinical Data – A Guide for Manufacturers andNotified Bodies – Appendix 1: Clinical Evaluation of CoronaryStentsMEDDEV 2.7.2; December 2008Guide for Competent Authorities in Making an Assessment ofClinical Investigations NotificationMEDDEV 2.12/2; May 2004Clinical Evaluation - Post Market Clinical Follow-upGHTF final documentsSG5/N1:2007 Clinical Evidence – Key definitions and ConceptsSG5/N2:2007 Clinical EvaluationHarmonized/International standardsEN ISO 14155-1: 2009Clinical investigation of medical devices for human subjects – Part1 General requirementsEN ISO 14155-2: 2009Clinical investigation of medical devices for human subjects – Part2 Clinical investigation plansEN ISO 14971: 2009Application of risk management to medical devicesOther ReferencesWorld Medical Association – Declaration of Helsinki - Ethicalprinciples for medical research involving human subjects4 DefinitionsClinical Data:The safety and/or performance information that is generated fromthe use of a device. Clinical data are sourced from:— clinical investigation(s) of the device concerned; or— clinical investigation(s) or other studies reported in thescientific literature, of a similar device for which equivalenceto the device in question can be demonstrated; or— published and/or unpublished reports on other clinicalexperience of either the device in question or a similar devicefor which equivalence to the device in question can bedemonstrated.Clinical Evaluation:The assessment and analysis of clinical data pertaining to a medicaldevice to verify the clinical safety and performance of the devicewhen used as intended by the manufacturer.Clinical Evidence:The clinical data and the clinical evaluation report pertaining to amedical device.Clinical Investigation:Any systematic investigation or study in or on one or more humansubjects, undertaken to assess the safety and/or performance of amedical device.Clinical Investigation Plan:Document that states the rationale, objectives, design and proposedanalysis, methodology, monitoring, conduct and record-keeping ofthe clinical investigation.Clinical Performance:The ability of a medical device to achieve its intended purpose asclaimed by the manufacturer.Clinical Safety:The absence of unacceptable clinical risks, when using the deviceaccording to the manufacturer’s Instructions for Use.Conformity Assessment:The systematic examination of evidence generated and proceduresundertaken by the manufacturer, according to Article 9 of directive90/385/EEC and Article 11 of directive 93/42/EEC, to determine thata medical device is safe and performs as intended by themanufacturer and, therefore, conforms to the EssentialRequirements according to Annex 1 of directive 90/385/EEC andAnnex I of directive 93/42/EEC.Device intended for Clinical Investigation:any device intended for use by a duly qualified medical practitionerwhen conducting investigations as referred to in Sections 2.1 ofAnnex 7 of directive 90/385/EEC and section 2.1 of Annex X ofdirective 93/42/EEC in an adequate human clinical environment. Endpoint: Indicators measured or determined to assess the objectives of a clinical investigation, prospectively specified in the clinicalinvestigation plan. (EN ISO 14155_2:2009, modified)Residual Risk: Risk remaining after risk control measures has been taken (EN ISO 14971:2009).Risk Management:The systematic application of management policies, procedures andpractices to the tasks of analysing, evaluating, controlling andmonitoring risk (EN ISO 14971:2009).5 General Principles When Considering the Need for a ClinicalInvestigationClinical EvaluationAccording to Annex 1.I.5a of directive 90/385/EEC and Annex I.I.6a of directive 93/42/EEC demonstration of conformity with the essential requirements must include a clinical evaluation in accordance with Annex 7/Annex X of the respective directive.As a general rule, confirmation of conformity with the requirements concerning the characteristics and performances referred to in sections I.1 and I.3 of annex I of directive 90/385/EEC and in sections I.1 and I.2 of annex I of directive 93/42/EEC under the normal conditions of use of the device, and the evaluation of the side-effects and of the acceptability of the benefit/risk ratio referred to in Section I.5/I.6 of Annex I of directives 90/385/EEC and 93/42/EEC respectively, must be based on clinical data.The kind and amount of clinical data needed will primarily depend on the specifics of the clinical claims with regard to clinical performance, considerations of clinical safety, including determination of undesirable side-effects and on risk management output, namely determination of residual risks and favorable benefit/risk ratio. Some factors that may typically influence the specificity/extent of clinical datarequirements are listed in section 6 of this guidance. Different clinical claims/intended purposes of a device may often necessitate different clinical data. For example, in the case of the closure of the heart defect patent foramen ovale, clinical performance/safety data and benefit/risk-considerations may vary in different intended purposes such as stroke prevention or migraine crisis prevention.Conducting a proper clinical evaluation will demonstrate which clinical data are necessary, which clinical data can be adequately supplemented by other methods, such as literature search, prior clinical investigations, clinical experience or by using suitable clinical data from equivalent1 devices, and which clinical data remain to be delivered by clinical investigations (see MEDDEV 2.7.1 Rev.3: “Clinical Evaluation: A Guide for Manufacturers and Notified Bodies”).The clinical evaluation and its documentation must be actively updated with data obtained from the post-market surveillance. New such data as well as considerations for new or changed intended purposes need updating of the clinical evaluation and may indicate necessity of additional clinical investigations.When must/should a clinical investigation be undertaken?The Conformity Assessment process for active implantable medical devices as well as for class III and implantable medical devices requires that a clinical investigation is undertaken unless it is duly justified to rely on existing data (section 1.2 of Annex 7 of directive 90/385/EEC and section I.1a of Annex X of directive 93/42/EEC ). Any such justification will have to be based on a proper clinical evaluation.Depending on clinical claims, risk management outcome and on the results of the clinical evaluation, clinical investigations may also have to be performed for non-implantable medical devices of classes I, IIa and IIb.Additional clinical investigations may be feasible to corroborate the existing clinical evidence with regard to aspects of clinical performance, safety, benefit/risk-ratio or to determine relative effectiveness and safety with suitable comparators.6 General Principles of Clinical Investigation DesignAny clinical investigation must:• be part of the clinical evaluation process;• follow a proper risk management procedure to avoid undue risks;• be compliant with all relevant legal and regulatory requirements;• be appropriately designed (see below);• follow appropriate ethical principles (see Section 7).1 The concept of equivalency encompasses technical, biological and clinical equivalency.Basic legal and administrative provisions given in directives 90/385/EEC and 93/42/EECArt. 4 of the two directives require that Member States shall not create any obstacle to devices intended for clinical investigation being made available to medical practitioners or authorized persons for that purpose if they meet the conditions laid down in Article 10/15 and in Annex 6/VIII of the respective directives. These devices shall not bear the CE marking.Art. 10/15 of the directives contain the administrative provisions for clinical investigations, Annex 6/VIII respectively the contents and provisions for the statement and documentation required.Annexes 7/X, sections 2.2 relate to ethical provisions, sections 2.3 specify basic methodological aspects of clinical investigations.Further legal and regulatory/administrative requirements may be valid at national/regional level.Factors to Influence Clinical Data RequirementsThe design of the clinical investigation, including the study objectives and statistical considerations, should provide the clinical data necessary to address relevant aspects of clinical performance, safety, including undesirable side-effects as well as the residual risks identified in the risk management process. Some factors that may influence the extent of clinical data requirements include, but are not limited to, the following:• type of device and/or regulatory classification;• novel technology/relevant previous experience;• clinical application/indications;• nature of exposure to the product, e.g.: surface contact, implantation, ingestion;• risks inherent in the use of the product, e.g.: risk associated with the procedure;• performance claims made in the device labeling (including instructions for use);• component materials and substances;• disease process (including severity) and patient population being treated;• demographic, geographic and cultural considerations (e.g.: age, race, gender, etc.);• potential impact of device failure;• period of exposure to the device;• expected lifetime of the device;• availability of alternative treatments and current standard of care; and• ethical considerations.Considerations for Device Study DesignsSome of the factors that need to be considered in the study design include, for example:• clear statement of objectives• appropriate subject population(s)• minimization of bias (e.g., randomization, blinding)• identification of confounding factors (e.g., concurrent medications, co-morbidities)• choice of appropriate controls (e.g., cohort, sham, historical), where necessary• design configuration (e.g., parallel, crossover, factorial)• type of comparison (e.g., superiority, non-inferiority, equivalence) Investigations should be planned in such a way as to maximize the clinical relevance of the data while minimizing confounding factors. Possible study designs include: • randomized controlled trials• cohort studies• case-control studies• case seriesThese are further explained in Appendix C of the document MEDDEV 2.7.1 Rev. 3 on Clinical Evaluation.In designing the study, statistical considerations should be prospectively specified and should be based on sound scientific principles and methodology. Care must be taken in developing a statistical plan that includes consideration of, for example, the following:•endpoints that are clinically relevant, clearly defined and assessed at a specified time point2• a testable hypothesis• statistical significance levels, power• sample size justification2 See e.g. critical aspects of end point definition for regulatory trials [D.B. Kramer et al, American Journal of Therapeutics 17, 2-7 (2010)]• analysis methodology (including sensitivity and poolability analysis)The design should ensure that the statistical evaluation derived from the investigation reflects a meaningful, clinically significant outcome.Discussion with a competent authority or a notified body may be appropriate when there is uncertainty as to whether the proposed clinical investigation plan is sufficient.Conduct of Clinical InvestigationsA properly conducted clinical investigation, including compliance to the clinical investigation plan and local laws and regulations, ensures the protection of subjects, the integrity of the data and that the data obtained is acceptable for the purpose of demonstrating conformity to the Essential Requirements. EN ISO 14155 outlines good clinical practice for clinical investigations of medical devices.Final Study ReportThe outcome of a clinical investigation has to be documented in a final study report (Annex 7/X, section 2.3.7 of directives 90/385/EEC and 93/42/EEC) This then forms part of the clinical data that is included in the clinical evaluation process and ultimately becomes integrated into the clinical evaluation report (see MEDDEV 2.7.1 Rev. 3) for the purposes of conformity assessment. The structure of a final study report is proposed in EN ISO 14155-1:2009.7 Ethical Considerations for Clinical InvestigationsIn their sections 2.2 of Annex 7/Annex X, directives 90/385/EEC and 93/42/EEC require: “Clinical investigations must be carried out in accordance with the Helsinki Declaration adopted by the 18th World Medical Assembly in Helsinki, Finland, in 1964, as last amended by the World Medical Assembly. It is mandatory that all measures relating to the protection of human subjects are carried out in the spirit of the Helsinki Declaration. This includes every step in the clinical investigation from first consideration of the need and justification of the study to publication of the results.”As a general principle, “the rights, safety and wellbeing of clinical investigation subjects shall be protected consistent with the ethical principles laid down in the Declaration of Helsinki” (EN ISO 14155-1:2009).It is ethically important in deciding to conduct a clinical investigation that it should generate new data and answer specific safety and/or performance questions that remain unanswered by the current body of knowledge. The desire to protect human subjects from unnecessary or inappropriate experimentation must be balanced with the need to protect public health through the use of clinical investigations where they are indicated. In all cases, however, care must be taken to ensure that the necessary data are obtained through a scientific and ethical investigational process that does not expose subjects to undue risks or discomfort. The rights, safety and well-being of subjects are paramount and appropriate trial design and conduct is essential to generate meaningful data.。

The Guidelines have been carefully drafted through a process of intensive consultation of the various interest parties (competent authorities, Commission services, industries, other interested parties) during which intermediate drafts were circulated and comments were taken up in the document. Therefore, this document reflects positions taken by representatives of interest parties in the medical devices sector.Commission européenne, B-1049 Bruxelles / Europese Commissie, B-1049 Brussel – Belgium.Version 2003-03-27EVALUATION OF CLINICAL DATA:A GUIDE FOR MANUFACTURERS AND NOTIFIEDBODIES1.Introduction and purposeIt is the primary purpose of this document to provide guidance to Manufacturers on reviewing and analysing clinical data and to Notified Bodies when reviewing the manufacturers evaluation of clinical data as part of the conformity assessment procedures required by 90/385/EEC (AIMD) [1] and 93/42/EEC (MDD) [2].This document will also assist manufacturers, by providing guidance on what is ex-pected.2.BackgroundThe manufacturer must demonstrate that his intended purpose(s) and claim(s) made in relation to safety and performance are achieved, as referred to in the Directives. As a general rule, such demonstration will require clinical data (Annex X, 1.1 of MDD).Evaluation of clinical data as described in Annex X of the MDD and Annex 7 of the AIMD is particularly relevant to assessment of conformity with essential requirements given in MDD Annex I: General Requirements, sections 1 and 3 and AIMD Annex 1: General requirements, sections 1 and 2. Attention should also be paid to Annex I,I.6 (MDD) and Annex 1, I.5 (AIMD).3.Explanation of termsFor the purpose of this document:3.1 Clinical data is data which is relevant to the various aspects of the clinical safety and performance of the device. This must include data obtained from:(i) published and/or unpublished data on market experience of the devicein question; or a similar device for which equivalence to the device inquestion can be demonstrated; or(ii) a prospective clinical investigation(s) of the device concerned; or(iii) results from a clinical investigation(s) or other studies reported in the scientific literature of a similar device for which equivalence to thedevice in question can be demonstrated.3.2.The Evaluation of clinical data is the process by which clinical data from all se-lected sources (literature, results of clinical investigations and other) is as-sessed, analysed and deemed appropriate and adequate to establish conformity of the device with the pertinent essential requirements of the Directive as they relate to safety and performance, and to demonstrate that the device performs as intended by the manufacturer. The outcome of this process is a report which includes a conclusion on the acceptability of risks and side effects when weighed against the intended benefits of the device.4.Clinical data to be provided by the manufacturerThe Active Implantable Medical Devices Directive and the Medical Devices Directive state that as a general rule, and in particular in the case of implantable devices, active implantable devices and devices in Class III, evidence of the clinical performance and safety of a medical device is provided by means of clinical data, which is supplied by the manufacturer in accordance with Annex X (MDD) or Annex 7 (AIMD). The decision as to whether clinical data is necessary however must be taken for every device on the basis of the type of data required to demonstrate compliance with the relevant Essential Requirements, the claims being made for the device in question and the risk management assessment. All the conformity assessment procedures leading to CE marking, address the issue of clinical evaluation by the manufacturer. In the case of Annexes II and III, the Notified Body is involved. Clinical evaluation is based on the assessment of the risks and the benefits, associ-ated with use of the device, through either:(i) a compilation of relevant scientific literature, that is currently availableas well as, where appropriate, a written report containing a critical evaluation of this compilation (the "literature route"); or(ii)the results of all the clinical investigations relevant to the device in question (the "clinical investigation route"); or(iii) a combination of (i) and (ii) above. Where the clinical evaluation is based on such a combination, it should include an overall assessment. This assessment should take account of market experience, if available. It is important that the manufacturer relates the data to the specific device, having regard to the hazards identified (see 4.2).The manufacturer must demonstrate whether the available data is sufficient to establish conformity with the Directive, having regard to:(i) the demonstration of equivalence of the device to which the datarelates and the device(s) for which conformity is being assessed, andso the applicability of the findings to the device being assessed (seesection 4.3.1 (i)d) ); and(ii) the adequacy of the data in addressing the relevant aspects of Directive conformity.4.1. Manufacturer’s statement on the clinical data used to affix the CE markingThe manufacturer should include in the technical documentation a simple statement on the clinical data used to affix the “CE” marking. The statement should make clear whether that clinical data was obtained from the published literature or the results of clinical investigations or a combination of both. Where data relates to other devices, the statement should indicate analogy with which device(s) and how equivalence was established. The full clinical data used for CE marking should be included within the technical documentation.4.2.Identification of aspects of safety and performance to be addressedthrough clinical dataThe manufacturer is required by the Directive to perform a risk analysis. A risk analysis is important in helping the manufacturer identify known or reasonably fore-seeable hazards associated with use of the device, and decide how best to estimate the risks associated with each hazard1. From the results of the risk analysis, the manufacturer lays out how each risk is addressed and decides on the acceptability of risks when weighed against the intended benefits.The risk analysis includes technical and clinical aspects relating to the particular device concerned. It should distinguish between aspects associated with:(i)the medical procedure for which the device is intended;eg the risks versus benefits associated with extracorporeal lithotripsy ascompared with conventional (surgical and non-surgical) methods ofkidney stone removal.(ii)the technical solutions adopted;eg the risks versus benefits associated with different technologies ofextracorporeal lithotripsy such as those involving generating shockwaves with electric sparks (electrohydraulic method), with anelectromagnetic generator or a piezoelectric system.(iii)aspects specific to the design and use of the particular device concerned;1The loss/absence of the performance of a given device as claimed by the manufacturer and which could result in the loss of benefit of a treatment may be considered a hazard.eg the risks versus benefits associated with the shock wave couplingmethod, size of the focal zone, the stone localisation and targetingsystem (X-ray, ultrasound) and the trigger methodThis distinction should be used to identify the type and specificity of clinical data needed. Where the available data is not sufficient to address the identified clinical hazards relating to one or more of the above aspects, a clinical investigation(s) will be needed (see also section 4.4.1). The objectives of the clinical investigation(s) should focus on those aspects not sufficiently addressed by the available data. The manufacturer should also set out the intended benefits of the device and relate those to the accepted benefits associated with the generally acknowledged “state of the art”4.3.Literature routeDue regard needs to be paid to the extent to which the published data are relevant and applicable to the relevant characteristics of the device under assessment and the medical procedure for which the device is intended.A literature review should be performed by person(s) suitably qualified in the relevant field, knowledgeable in the “state of the art” and able to demonstrate objectivity.4.3.1RequirementsWhen the manufacturer's clinical evaluation to be submitted to the Notified Body takes the form of a review of the relevant scientific literature, the following requirements should be fulfilled:(i) Methodologya)GeneralA protocol for the identification, selection, collation and review of relevantstudies should be written and preferably be based on recognised practice for systematic review for literature.b)ObjectiveThe objective of the literature review should be clearly defined. The types of studies that are relevant to the objective of the literature review should be specified, taking into account the already well established knowledge of the device.c)Identification of dataData should be taken from recognised scientific publications. Unpublished data should also be taken into account in order to avoid publication bias.The literature review should state:·the sources of data and the extent of the searches of databases or other sources of information;·the rationale for the selection/relevance of the published literature;·the reasons for believing that all relevant references, both favourable and unfavourable, have been identified;·the criteria for exclusion of particular references together with a justification for this exclusion.Note: possible data sources for a systematic literature review are for example:· medical and paramedical databases· technical papers from relevant Standards Committees·foreign language literature·“grey literature” (theses, internal reports, non peer review journals, the internet, industry files)·references listed in primary sources·other unpublished sources known to experts in the field (obtained by personal communication)·raw data from published trials (obtained from personal communication)d)Relevance of dataA literature review should clearly establish the extent to which the literaturerelates to the specific characteristics and features of the device under consideration.If the published studies do not directly refer to the device in question, the following must apply.·The manufacturer must demonstrate equivalence in all the following essential characteristics with the device, which is the subject of thepublished reports. Equivalence means:Clinical:-used for the same clinical condition or purpose;-used at the same site in the body;-used in similar population (including age, anatomy, physiology);-have similar relevant critical performance according to expectedclinical effect for specific intended use.Technical:-used under similar conditions of use;-have similar specifications and properties eg tensile strength,viscosity, surface characteristics-be of similar design;-use similar deployment methods (if relevant);-have similar principles of operationBiological:-use same materials in contact with the same human tissues orbody fluids;To be equivalent, the devices should have similarity with regard to the clinical, technical and biological parameters with special attention to the performance, principles of operation and materials; or if there are differences identified, an assessment and demonstration of the significance these might have on safety and performance must be set out.For example we can consider the case where the device under consideration and the device referred to in the published studies do not have the same principles of operation ie the new device has a new principle of operation.Since a new mechanism of action does not necessarily result in a new clinical benefit, demonstration of the clinical benefit of the new device has to be generated by data resulting from a specifically designed clinical investigation since the 2 devices cannot be considered equivalent.·The manufacturer must be able to demonstrate the adequacy of the data in addressing the aspects of conformity set out in the objectivee)Assessment of clinical dataThe literature review should make clear the significance that is attached to particular references based on a number of factors. These include:·the relevance of the author’s background and expertise in relation to the particular device and/or medical procedure involved.·whether the author’s conclusions are substantiated by the available data·whether the literature reflects the current medical practice and the generally acknowledged “state of the art “ technologies.·whether references are taken from recognised scientific publications and whether or not they have been reported in peer reviewed journals·the extent to which the published literature is the outcome of a study/studies which have followed scientific principles in relation to design,for example, in having demonstrable and appropriate endpoints, inclusionand exclusion criteria, an appropriate and validated number of patientssubmitted, carried out for an appropriate duration, providing evidence andanalysis of all adverse incidents, deaths, exclusions, withdrawals andsubjects lost follow-up and identifying an appropriate statistical plan ofanalysis.Ideally, evidence should be generated from a clinical trial (controlled if appropriate), properly designed cohort/case controlled study, well documented case histories or sequential reports conducted by appropriate experienced experts, whether in relation to the device itself or an equivalent device. If unpublished data is being included in the assessment, the literature review will need to weigh the significance that is attached to each report.The evidence should not consist of:·isolated case reports;· random experience;·reports lacking sufficient detail to permit scientific evaluation (including lack of accepted and validated statistical design if this is relevant to the design of the intended study);· unsubstantiated opinions.(ii) Critical evaluation of the literatureThe literature review should contain a critical evaluation of the literature. This critical evaluation should:·be written by a person suitably qualified in the relevant field, knowledgeable in the “state of the art” and able to demonstrate objectivity;·contain a short description of the medical device, its intended functions, description of the intended purpose and application of use;·contain an analysis of all the available data considered, both favourable and unfavourable;· establish the extent to which the literature relates to the specific characteristics and features of the device being assessed, taking due accountof the extend of similarity between the device(s) covered by the literature and the device under assessment;·demonstrate that those aspects of the use of the device, including performance, addressed in the clinical part of the risk analysis are met as claimed by the manufacturer, and that the device fulfils its intended purpose as a medical device;·analyse the identified hazards, the associated risks and the appropriate safety measures of patients, medical staff and third parties involved in the study/studies, for example by reference to the manufacturer’s risk analysis (see also ISO14155-2);·contain a risk analysis relevant to the device design, materials and procedures involved, taking into account any adverse events, results of post-market surveillance studies, modifications and recalls (if known) (see also ISO14155-2);·contain a description of the methods of weighting of different papers and the statistical methods of analysis employed taking into account the assessment methods, the type and duration of study and the heterogeneity of the population included within the study. Particular attention should be given in circumstances where there are repeated publications on the same group of patients by the same authors in order to avoid overweighting the experience;·include an analysis of the market experience of the same or similar devices, including the results of post-marketing studies, post-market surveillance and short- and long-term adverse events;·contain a list of publications appropriately cross-referenced in the evaluation;·if the clinical data relates to an equivalent device, contain a statement that equivalence with all the relevant characteristics has been demonstrated;·include a conclusion with a justification, including an assessment of any probable benefit to health from the use of the device as intended by the manufacturer, against probable risks of injury or illness from such use taking account of the “state of the art”. If applicable, the findings should be compared with other studies covering the same field of application. These studies may involve other modalities, including alternative medical devices, medical therapy, surgery or other accepted health care methods provided they employ methods which are generally accepted as being common practice. The conclusions should make clear how the objectives of the literature review have been met and identify any gaps in the evidence necessary to cover all relevant aspects of safety and performance.Note 1:conclusions should be relevant in the field of use,indications, contra-indications and instructions for use intended by themanufacturerNote 2:the critical evaluation should be signed and dated by theauthor4.3.2 Conclusions from Analysis of Literature ReviewAs a result of a literature review, the Notified Body needs to be able to answer the following:· that the manufacturers’ conclusions are valid;·that the data, taken together with the available pre clinical data, is sufficient to demonstrate compliance with the essential requirementscovering safety and performance of the device in question under normalconditions of use; or·identify gaps in the demonstration of compliance with the relevant essential requirements or in the demonstration of equivalence that needaddressing through the means of a specifically designed clinicalinvestigation(s); and·that the claims made in the device labelling are substantiated by the clinical data taken together with the pre-clinical data.The manufacturer’s report of the literature review should be written in a format that enables the Notified Body to answer the questions above.4.4Clinical investigations route4.4.1.Need for clinical investigation(s)When reviewing the manufacturer’s evaluation of clinical data and whether or not a clinical investigation(s) is needed as part of this, due regard should be paid to NB-MED/2.7/R1 [5].4.4.2.Conduct of clinical investigationsWhere the results of clinical investigation(s) form part of the clinical data, the clinical investigations should comply with the relevant sections of Annex X MDD or Annex 7 AIMD. Compliance with the EN 540 [3] carries the presumption that the design, conduct and monitoring of the clinical investigation(s) conforms with the requirements of these Annexes. Whilst not carrying such a presumption of conformity, other equivalent standards may be used.2[4]4.4.3Requirements2Where justified, the Notified Body may require further information to assess the manufacturers clinical investigation data.When the manufacturer’s clinical evaluation to be submitted to the Notified Body takes the form of presentation and analysis of results from a specifically designed clinical investigation(s) involving the device in question, the following requirements should be fulfilled.(i) Identification of Relevant DocumentsThe following documents must be requested:·copy of the Protocol submitted to the Competent Authority for which no grounds for objection were raised;·copy of the letter of “no objection” from Competent Authority/Authorities (if available), together with comments made (was this a first submission to aCompetent Authority? If rejected, a copy of the original “grounds forobjection” should be requested);·copy of the Ethics Committee opinion(s) and comments (was this the first submission to Ethics Committee? If previously rejected, a copy of theletter of objection should be requested);·copy of the signed and dated final report.(ii) Information to be checkedThe following must be checked in all cases.·Letter of “no objection” from the Competent Authority(ies)·Clinical Investigation Plan (CIP): Is the CIP used for the clinical investigation the same as that submitted to the Competent Authority?Particular attention should be paid to:-number of patients entered-objectives of investigation(s) (in particular which Essential Requirements are being addressed)-duration of investigation(s) and patient follow up (short and long term)-end points in terms of diagnostic tools and patient assessment-inclusion and exclusion criteria;·If parameters, especially those mentioned above, are not as set out in the original CIP, the rationale for non adherence (particularly important to notewhether inclusion numbers and duration of study are cut short);·Identification of any changes to CIP and rationale for any such changes (important to ensure Competent Authority was notified of changes, if thisis relevant);·Where the clinical investigation(s) was performed outside the EU, the manufacturer must demonstrate that the use of the device (includingclinical practice and techniques) and patient population are equivalent tothose for which the device will be used within the EU (if relevant).(iii) FinalReportThe contents of the Final Report should always be checked and should contain the following informationa) SummaryA structured abstract should be provided, presenting the essentials of thestudy, including:·title of investigation(s);·identification of the medical device(s), including names, models as relevant for complete identification;·name of sponsor;· statement indicating whether the investigation(s) was performed in accordance with CEN/ISO Standards;·objectives;·subjects;·methodology;·investigation(s) initiation and completion dates, including date of early termination, if applicable;·results;·conclusions;·authors of report;·date of report.b) IntroductionA brief statement placing the study in the context of the development of themedical device in question and an identification of guidelines followed inthe development of the Protocol.c) Materials and methods· devicedescription;·summary description of the device and its intended use, together with any modifications performed during the investigation;·Clinical Investigation Plan summary.d)Summary of the clinical investigation planThis should be accompanied by any modification described.
