Hello Wiebe,
Thank you for your narrative, "...it makes sense to conduct a clinical evaluation for every medical device, even if the device does not require clinical data. The clinical evaluation is not only used to present and evaluate clinical data, but also to establish the state of the art, demonstrate that various sources were examined for clinical data (a null result is still a result), and to document the strategy for proving clinical safety and performance even if it is decided that clinical data are not deemed appropriate..."
Again, statements like, "...it makes sense to conduct a clinical evaluation [i.e., of clinical data] for every medical device, even if the device does not require clinical data..." continue to boggle my mind. Does that not boggle anyone else's mind?
In addition, I question the notion of requiring clinical data / evaluation in order to establish the state-of-the-art. Indeed, much has been said in this Forum and elsewhere about the meaning of "state-of-the-art"; so, I won't rehash that here. But in a nutshell, it is current and longstanding precedent (e.g., see MDCG 2021-5, MEDDEV 2.7/1 revision 4, IMDRF, etc.) for Europe's Union that "state-of-the-art" may be demonstrated by means other than clinical data, such as via applicable standards, guidance documents, and experience. So again, reflexive demands for clinical data to show the state-of-the-art are another overreach in my opinion. It is important to note that MDCG 2020-6 discusses how to establish state-of-the-art for the specific context of devices that require clinical data. Taking such things out of context can be costly and doesn't undo the other longstanding general precedents for establishing the state-of-the-art via other means, like via applicable standards, guidance documents, and experience, regarding devices for which clinical data are not appropriate.
Similarly, the notion of demonstrating that various sources were examined for clinical data seems questionable regarding a device for which clinical data are not appropriate. Maybe there is value in that for business or marketing reasons, but not so much regarding demonstrating conformity with the EU MDR's general safety and performance requirements (GSPR).
On that note, regarding the demonstration of "clinical safety and performance", I'm unable to locate the notion of "clinical safety and performance" anywhere in the EU MDR. I note that "clinical safety" is mentioned only three times in total, and all in the context of devices that require clinical data. Accordingly, asserting a need to demonstrate "clinical safety" via clinical evaluation of clinical data regarding devices for which clinical data are not appropriate again raises a circular and overreaching quagmire, at least for regulatory/legislative intents and purposes. I think we should be careful not to equate demonstration of "clinical safety and performance" with the EU MDR's intent for conformity with "general safety and performance" requirements (GSPR). While GSPR may sometimes include demonstration of clinical safety via clinical data, it remains that GSPR conformity doesn't always require demonstration of clinical safety [see Article 61(10)].
Thanks also for your given additional examples (e.g., MDCG 2020-6) reiterating Europe's Union practice of demanding clinical data for all devices, even regarding devices for which clinical data are not appropriate. MDCG 2020-6 is indeed another good example of the aforementioned circularity. Specifically, the ultimate context/purpose/intent of MDCG 2020-6 is to define "sufficient clinical evidence" regarding devices for which clinical data are necessary. A tease of sensibility is given when, for context, MDCG 2020-6 reminds us that clinical data are not required for all devices and then it recites Article 61(10) accordingly. But then it goes on to convolute the issue by apparently indicating that clinical data and evaluation are, in some fashion or another, still being demanded regarding devices for which clinical data are not actually appropriate. It then goes on to exacerbate the issue even further by categorizing three types of non-clinical data (e.g., bench data) as clinical data, consequently making such non-clinical data subject to clinical evaluation.
I might be able to get accustomed to the awkward semantics of requiring a "clinical evaluation" of non-clinical data as long as the data in that evaluation are just that: non-clinical data. But what I think pushes over the line into nonsensical regulatory overreach and overburden is requiring clinical data [Article 2(48)] when non-clinical data are sufficient for GSPR.
MDCG 2020-5 and its attendance to showing clinical "equivalence" between a subject device and a different device are for the context of devices that require clinical data. Indeed, regarding Article 61(1)'s general requirement for clinical data for all devices, it reminds us of Article 61(10)'s exception to this when MDCG 2020-5 clarifies that, "...It may under certain circumstances be justified to demonstrate conformity without support of clinical data, see MDR, Article 61(10)..." Therefore, I don't recommend asserting MDCG 2020-5 as a precedent for demanding clinical data regarding devices for which clinical data aren't appropriate. That would be more overreach in my opinion.
As a regulatory professional who believes strongly in the principle of a least-burdensome regulatory approach when such an approach is already sufficient for guarding public health, I remain unconvinced about the value and legislative integrity of demanding that every device shall have clinical data and evaluation (i.e., a systematic and planned [and burdensome] process to continuously generate, collect, analyze and assess clinical data).

Hi Kevin,
Thanks for your insightful comment. I agree with you that there are inconsistencies in the way clinical data and evaluation are required. However, I do think that it makes sense to conduct a clinical evaluation for every medical device, even if the device does not require clinical data. The clinical evaluation is not only used to present and evaluate clinical data, but also to establish the state of the art, demonstrate that various sources were examined for clinical data (a null result is still a result), and to document the strategy for proving clinical safety and performance even if it is decided that clinical data are not deemed appropriate. I believe this is in line with the guidance provided by MDCG 2020-6 and MDCG 2020-5, which explain the purpose and scope of clinical evaluation and how it should be performed and documented. Perhaps the definition of clinical evaluation, which as you rightfully pointed out directly calls for clinical data (i.e. safety/performance data generated from the use of a device) should be broadened to include other data proving the safety and performance of a device.

Thank you, Wiebe for your reply. Your narrative, "...MDCG 2020-13. Section J of the CEAR asks for a clinical evaluation, but I do not see where it calls for clinical data as part of the justification to not use clinical data to demonstrate conformity..." perfectly demonstrates the dichotomous circularity of the issue:
"Clinical evaluation" [EU MDR Article 2(44)] fundamentally means a systematic and planned process to continuously generate, collect, analyze and assess the clinical data. Consequently, MDCG 2020-13 Section J's call for clinical evaluation is in effect a call for clinical data.
Similarly, Section J's questions:
- "Has any available clinical data for the device or an equivalent device been searched for and/or identified by the manufacturer?", and
- "...was the identified clinical data integrated in the clinical evaluation", and
- "Is clinical data available for similar devices, does this provide information with relevant to the safety and performance of the device under evaluation", and
- "Has the manufacturer conducted an appropriate search of scientific literature?",
are all calls for clinical data and clinical evaluation. These clinical data and evaluation requirements placed upon the manufacturer's justification for not needing clinical data again raise the dichotomous nature of the way this is being handled for Europe's Union. I also note that this dichotomous approach is not new, as it was born out of MEDDEV 2.7/1 revision 4.
In essence, it seems that clinical data and evaluation are always required for Europe Union's even when they aren't actually necessary for demonstrating conformity with the general safety and performance requirements. I hope that this paradigm will be reconsidered in realization that burdensome clinical data and evaluation aren't always needed or sensible for the purposes of general safety and performance requirements.

Hi anon,
The issue you identified may have to do with the interpretation of MDCG 2020-13. Section J of the CEAR asks for a clinical evaluation, but I do not see where it calls for clinical data as part of the justification to not use clinical data to demonstrate conformity. The CEAR is asking whether the manufacturer has searched for clinical data on their own device and similar devices. I believe it is very reasonable to complete the literature searches for the clinical evaluation as for any other device. Sometimes there are papers mentioning the device under evaluation, there may even be some clinical data. Any clinical data found may be supportive of the device's safety and performance but you would often see that it would be indirect clinical evidence (e.g. success of a procedure in which the device under evaluation was used). I have also seen people use the literature searches to demonstrate that indeed no clinical data are available and it cannot be reasonably expected that trials are done on the type of device (in other words, use searches that return no result as supportive evidence for the 61.10 strategy).
Regards,
Wiebe

EU MDR Article 61(10) provides criteria for waiver from the need for clinical data. Those criteria are based on the results of the manufacturer's risk management and on consideration of the specifics of the interaction between the device and the human body, the intended clinical performance, and manufacturer's claims.
Yet MDCG 2020-13 Section J instructs notified bodies to call for clinical data as part of the manufacturer's claim that clinical data aren't required. And I similarly have an Authorized Representative (AR), one rather new to the scene, echoing this as a precondition of representation and registration for a Class I NS/NM/NRSI device. In essence, these interpretations are making a circular argument that clinical data, along with clinical evaluation of those data, are required in order to justify that clinical data aren't required.
In contrast, I've previously seen a different AR accept an Article 61(10) clinical data waiver without providing clinical data, which is what seems more in line with Article 61(10)'s intent (allowing for the reasonable notion that clinical data aren't always appropriate or needed for demonstration of conformity). Likewise for example in other jurisdictions like the U.S. and Canada, it is routine to grant marketing authorization for low risk (and oftentimes even moderate risk) devices without clinical data.
What are your thoughts and experiences about the MDCG's and some ARs assertion that clinical data are required in order to claim that clinical data aren't required?
