Abstract
This article comments on the new approach to the clinical evaluation of medical devices in the European Union (EU), which adds consideration of intended clinical benefits to the traditional focus on safety and performance. The article also discusses types of clinical benefits that may be claimed and how evidence for them may be generated.
In the EU, determining the benefit-risk profile is an existing core requirement of the clinical evaluation performed according to MEDDEV 2.7/1 Rev 4 guidelines, but under the new Medical Device Regulation (MDR), “intended” clinical benefits must be determined first.
The MDR sets high standards for ensuring reliable data are generated from clinical investigations. It stipulates that the endpoints of clinical investigations should include clinical benefits. However, many clinical-use questions arise only after a device is made widely available to patients. For all medical devices, particularly for on-the-market devices never subjected to randomized controlled trials and for new devices developed when these trials were inappropriate/impossible, the postmarket phase of the device is a valuable source of clinical-benefit data. Postmarket clinical follow-up can corroborate and refine predictions of clinical benefits over time. Indirect clinical effects, which may affect treatment adherence and influence patients’ well-being, may surface in the postmarket phase.
Real-world clinical data will improve the manufacturer’s understanding of their device’s clinical benefits, potentially changing claims of intended clinical benefits in subsequent clinical evaluations. A paradigm change in clinical evaluation of medical devices in the EU will ensue when manufacturers ensure that their devices deliver real-world clinical benefits.
