New regulations for clinical trials of medical devices

Switzerland is adapting its medical devices regulations to the new EU rules in the interests of patient safety and EU market access for the Swiss medical devices industry. The changes will also have implications for human research legislation.

Current Note: As a result of the Covid-19 pandemic, the European the Commission has decided to postpone the entry into force of the Regulation (EU) 2017/745 on medical devices (MDR) for 12 months, i.e. until 26 May 2021.
Switzerland is following this adjustment and is therefore also postponing the entry into force of the revised human research regulations by one year to 26 May 2021. Further information can be found on the website of the Therapeutic Products Act (TPA).

What are medical devices?

Items as varied as plasters, hospital beds, cardiac pacemakers, disinfectants and x-ray equipment, have one thing in common: They are all medical devices. In other words, they are products “which are intended to have, or are presented as having, a medical use and whose principal effect is not obtained with a medicinal product” (Therapeutic Products Act, TPA, Art. 4 let. b).

As a result of the new EU rulings, products that are used without a medical purpose will be considered to be medical devices if they are used as such or are associated with similar risks, for example coloured contact lenses that do not correct vision.

New EU Regulation on Medical Devices

In 2012 the EU Commission presented for discussion a draft for new, stricter rules for medical devices. This had been prompted by various serious incidents – for example flawed silicone breast implants or defective hip implants.

In 2017 the EU finally approved two new regulations, one on medical devices (MDR) and one on in vitro diagnostic devices (IVDR). These have been coming into force in stages since 26 November 2017.

You can find more information about these regulations and the changes to Swiss law on the website on the Therapeutic Products Act (TPA). This is the law mainly affected by these changes.

Better quality assurance for medical devices

The new rules are primarily designed to better protect patients from defective medical devices. Consequently, manufacturers will, in future, have to submit stronger scientific evidence to substantiate the safety and quality of their devices before being allowed to place them on the market. They will also have to continue recording data after market launch. This explains why Switzerland is also adapting the laws and ordinances relating to human research as part of the revision of the TPA. Due to the Covid-19 pandemic, the amended rules will enter into force in May 2021, one year later than planned, at the same time as the MDR.

EU rules affect the law on human research and its implementation

Switzerland and the EU pursue the same objectives when it comes to regulating research:

  • Protect affected persons
  • Quality and transparency of research
  • A regulatory environment that is as favourable to research as possible

The EU embodies these objectives in the context of market access to medical devices, whereas the HRA regulates the research independently of market access. There is a need for action at implementation level: the cantonal ethics committees and Swissmedic implement the procedures for approving and reviewing research projects with medical devices. They will now have to adapt and, in some cases, reorganise these procedures.

Certain EU definitions are now incorporated into Swiss law. For example, the definition of a "clinical trial" with a medical device now corresponds to the definition of a "clinical investigation" in the MDR.  The categorization of individual research projects also changes. The transparency requirements of the MDR go further than in Switzerland, especially with regard to the documents of the approval procedure and the publication of the research results.

New ordinance on clinical trials with medical devices  

The new definitions in the EU rules has prompted the Federal Council to propose a new “Ordinance on clinical trials with medical devices (ClinO-MD)”. The ClinO-MD will conveniently list in one legal text all the provisions relating to research with medical devices.

The consultation for the amended ordinance took place from 15 May to 5 September 2019.

The amended human research regulations were scheduled to enter into force in May 2020 but have been postponed by one year due to the Covid-19 pandemic.

Research with in vitro diagnostics (IVD) will remain regulated in the ClinO for the time being. It is to be included in the ClinO-MD at the same time as the planned start of validity of the IVDR on May 26, 2022.

The consultation on the amending decree of the ClinO-MD concerning the inclusion of research with IVDs is planned for spring 2021.

Implementation of the regulations in the European Union

The FOPH is actively monitoring developments in the European Union regarding the EU regulations on medical devices. Starting in August 2019, the FOPH will publish regular updates on the implementation of the regulations in the EU and its member states. The reports will appear in English and can be found under the heading ‘Documents’.

Revision of medical devices legislation

The safety and quality of medical devices will be improved. Switzerland is comprehensively revising its medical devices legislation in close correlation with the new EU regulations for medical devices.
