 EU member states. The UK’s Medicines and Healthcare products Regulatory Agency (“MHRA”) conducted a comprehensive consultation in 2021 on proposals to develop a new UK regime for medical devices in the UK. The proposals include more closely aligning definitions for medical devices and in vitro medical devices with internationally recognized definitions and changing the classification of medical devices according to levels or risk. The proposals are intended to improve patient and public safety and increase the appeal of the UK market. Core aspects of the new regime are planned to come into force on July 1, 2025, with strengthened post-market surveillance proposals to be introduced ahead of this in 2023. Under the Medical Devices (Amendment) (Great Britain) Regulations 2023, CE marked European medical devices will continue to be accepted for sale in the UK until 2028 or 2030 (depending on the type of device).

The approval must be obtained from two separate entities: the National Competent Authority (“NCA”), and one or more Ethics Committees. The NCA of the EU member states in which the clinical trial will be conducted must authorize the conduct of the trial, and the independent Ethics Committee must grant a 19

positive opinion in relation to the conduct of the clinical trial in the relevant EU member state before the commencement of the trial. Any substantial changes to the trial protocol or other information submitted with the Clinical Trial Applications (“CTA”) must be submitted to or approved by the relevant NCA and Ethics Committees. Under the current regime all suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical trial must be reported to the NCA and to the Ethics Committees of the EU member state where they occur. A more unified procedure applies under the new CTR. A sponsor is able to submit a single application for approval of a clinical
