Compared to the Medical Device Directive (MDD) 93/42/EEC, the Medical Device Regulation (MDR) No. 2017/745 introduces a life-cycle approach to ongoing CE Marking compliance; it is a process, not a project. One output of the clinical evaluation process is demonstrating clinical performance of your medical device, i.e. demonstrating that your device performs as intended and has benefit to patients. Clinical data in support of performance can come from many sources including: clinical literature, trials, usability, post-market clinical follow-up (PMCF), the state-of-the-art, and/or from “equivalent” devices.
Using clinical justifications based on device equivalence has been standard practice in the EU for quite some time. This is to avoid having to conduct redundant pre- or post-market clinical studies to prove safety and performance. Compared to the MDD, the MDR specifies stricter requirements for comparative evaluations used to claim equivalency. The best strategy for MDR compliance would be one that does not rely on an equivalence argument; however, to leverage one, device manufacturers will need to produce a greater volume of data, along with a more rigorous interpretation of that data than previously required. Full demonstration of clinical, biological, and technical equivalence is required. Two of the three will not be sufficient. Some key points to consider are:
What about claiming equivalency to a product that is not CE Marked or sold in the EU? In that case, you would have to make a very good case to your Notified Body why the data is transferrable to an EU population and analyze any safety and performance gaps related to the clinical performance.
Managing the transition from the MDD to the MDR will involve a lot of work and the expert MED Institute scientific communications team is here to help. We can review your technical documentation and current clinical evaluation reports and help with a plan moving forward.
