For a clinical investigation involving a non-CE-marked medical device (i.e. a new or substantially modified device, or an existing device with a new function, feature or material), or a CE-marked device being used for a new intended purpose, the sponsor is likely to require a Notice of No Objection from the MHRA prior to commencing a study.


There are certain circumstances where use of a non-CE-marked device used within a healthcare establishment may not be covered by the provisions of the Medical Devices Regulations/Directives. Further advice on this can be found on the MHRA website.
