The blog series continues this year during Advent with our three-part “Advent Special”. We would like to provide you with comprehensive information about the important interfaces between the various types of clinical trials and the technical documentation and the relevant documents.

The special thing about our campaign is that the contribution is spread over the first three weeks of Advent. Each week, one type of clinical trial and the respective interfaces are examined in detail. The topic of risk management in clinical trials will continue in January.  

The first part of our blog special dealt with the interfaces in the “approval study” (clinical trials in accordance with Article 62 of the MDR). This second part 2 now highlights the PMCF studies (Article 74 of the MDR, MPDG, ISO 14155). The third and final part will explain the interfaces in DiGA studies next week .

KP (clinical examination)

MDR (medical device regulation; Regulation 2017/745)

MPEUAnpG (the Medical Devices EU Adaptation Act was passed as law by the Bundestag on May 25, 2020. This MPAnpG-EU describes the Medical Devices Implementation Act (MPDG) in Article 1)

MPDG (the MPDG will gradually replace the Medical Devices Act (MPG) from May 26, 2021 and will be legally binding for all manufacturers and operators of medical devices in Germany).

Part 2: Interfaces to technical documentation in PMCF studies and connection to MDR

1 Introduction

The correct term for a clinical trial involving medical devices is “clinical trial”.

A distinction is made between the following types of clinical trials:

• Basic research: other clinical trials (MDR Article 82)
• Pilot study/approval study: clinical trials to demonstrate the conformity of products (MDR Article 62)
• PMCF study: clinical trials related to products bearing the CE marking (MDR Article 74)

In addition, there is now the so-called DiGA study, especially in Germany:

• Study with a digital health application (DiGA) to demonstrate positive care effects in order to obtain reimbursement status.
• d. R. with CE marked medical device: PMCF study
• If planned into the approval process, an approval study is also possible

Fig. 1: Types of clinical trials

These different types differ in terms of the respective regulatory requirements and thus in terms of the different interfaces to the technical documentation of the medical device to be examined.

Special feature of PMCF studies:

A PMCF study that takes place with a CE-marked medical device within the scope of its intended purpose and without stressful examinations represents an exception to Article 74 of the MDR:

Figure 4: Article 74 of the MDR (Source: presentation slides, BfArM event, https://www.bfarm.de/DE/Service/Events/Dialogveranstaltungen/2021/210505-klinische_Pruefungen_von_MP.html )

Regardless of this, the documents according to Annex XV Chapter II and Articles 80ff of the MDR are still binding.

2. Documents to be submitted in PMCF studies

The following documents must be created for clinical trials involving a CE-marked product. Depending on whether Article 74 of the MDR applies, it will be submitted to the EC for a vote and to BfArM. If Article 74 does not apply, all that is required is professional advice from the responsible ethics committee in accordance with Section 15 of the Professional Code of Conduct for Doctors (BO). No matter which application is submitted, the following documents must be created and these are related to the technical documentation:

• Test plan - attachments according to appendix XV chapter. II 3 MDR.
• Clinical Investigator's Handbook - Appendices as per Annex XV Chapter. II 2 MDR.

The following documents are required from the technical documentation:

• clinical assessment - in accordance with Article 61 of the MDR.
• Instructions for use
• Biological safety test results
• How MP works/information about the MP (how MP works)
• How it works and further information about the medical device.
• Risk analysis and assessment including residual risks
• List basic security and performance requirements
• If necessary, suitable processing or sterilization processes
• Proof of CE marking (Required if the test product bears a CE marking.)

Table 1: Clinical trial documents and technical documentation

Since this is a CE-marked product, all of these documents are already present in the technical documentation and are particularly included in the test plan and the clinical examiner's manual.

The CE-marked medical device is therefore the test product tested in the PMCF study for which the clinical data is collected. I.e. the documents and results must refer to exactly this product and not to an earlier version!

Technical Documentation:

• Product description
• Intended use
• product specification
• Final clinical assessment with state of the art chapters and literature and risk-benefit assessment
• Risk management documentation according to ISO 14971: PHA, risk analysis, risk management report
• Instructions for use
• Classification
• Checklist of basic performance and security requirements
• List of standards
• Verification test reports
• Biosafety report (if applicable)
• Sterilization process documentation (if applicable)

2.2 Synergies

If you look at the list above, you will notice that this is almost all of the technical documentation.

A good example of using synergies when creating documents is the test plan. Many sections contain the same content as in other technical documentation documents. The intended purpose, the product description, etc. are just a few examples. In addition, the final clinical assessment includes state-of-the-art clinical data, which can also be used for the protocol and the clinical investigator's manual.

And here the digitalization of clinical trials plays a role again:

With the close integration of the clinical trial not only with the process of literature search and thus with the clinical assessment as reported in the penultimate blog post, but also with the technical documentation, digitalization of the essential documents of the clinical trial such as: b.

• Clinical trial plan (Appendix XV, Chapter II, Section 3 of the MDR)
• Clinical Investigator's Manual (Appendix XV, Chapter II, Section 2 of the MDR)
• clinical evaluation

possible.

The advantages of digitalization are obvious:

• more efficient work
• Target-oriented use of capacities
• Elimination of inefficiencies in the creation, maintenance and modification of technical documentation content, clinical evaluation and literature searches
• long-term reduction in care costs

Using the “Polarion” software application, interfaces such as purpose, risk management, usability, clinical evaluation, clinical testing can be assigned to projects and reused if necessary. The creation and maintenance of documents is thus significantly simplified and accelerated. In addition, redundancies and inconsistencies are avoided.

3. Outlook

our “ Advent special ” will focus on the interfaces to technical documentation in DiGA studies.
