Rules for clinical trials

Clinical trials involving human subjects must be safe and the welfare of the subjects must be protected. The results from clinical research must also be reliable. Therefore, clinical trials involving human subjects should be conducted according to national and international legislation and regulations. Moreover, additional rules apply for clinical trials with medicinal products or medical devices.

On this page you will find an overview of the legislation and regulations for clinical trials. On separate pages you will find more specific information on:

Laws, decrees and regulations

Are you an investigator or sponsor involved in a clinical trial with test subjects that falls under the Medical Research Involving Human Subjects Act (WMO)? Then you must comply with the provisions of this law. However, there are several other relevant decrees and regulations such as:

Additional legislation may also apply to a clinical trial. For example, the Medicines Act or the Medical Devices Act (see also clinical trials with medical devices). The ICH-GCP guidelines describe what clinical trials with a medicinal product require in order to comply with good clinical practice (GCP). This also applies to other clinical trials for which the research protocol states that it is or has been carried out according to GCP. The Helsinki Declaration also contains ethical principles for conducting clinical trials.

By the end of 2018, the European regulation 536/2014 will replace the European directive 2001/20. The regulation applies to clinical trials with medicinal products.

ICH-GCP Guidelines

The ICH-GCP guidelines explain what is covered by the term Good Clinical Practice. An 'Integrated Addendum’ is also available on  the ICP-GCP website. The ICH-GCP guidelines are a set of rules adopted during the International Conference on Harmonisation (ICH). It is a quality standard for designing, conducting, recording and reporting on clinical trials involving human subjects. The protection of the test subjects, their rights, health and safety is thereby guaranteed. This also applies to the integrity of the trial and the data obtained. The ICH-GCP guidelines are endorsed by the European Union, Japan and the United States as well as Australia, Canada, the Nordic countries and the World Health Organization (WHO).

When is the WMO applicable?

Prior to approval, clinical trials must be submitted to an accredited medical research ethics committee (MREC) or the Central Committee on Research Involving Human Subjects (CCMO). This concerns research that falls under the Medical Research Involving Human Subjects Act (WMO). The scientific research is explained as follows in the WMO:

medical research that includes subjecting people to treatment or requiring people to behave in a particular way‘ (Article 1, paragraph 1b of the WMO).

An online help tool is available on the CCMO website. This tool is helpful in determining whether a specific trial falls under the WMO and whether the trial should be assessed by an MREC and/or the CCMO. For questions on research not subject to the WMO, please consult the website 'Assessment framework for research not subject to the WMO’ (in Dutch).

Clinical trials with medicinal products

According to the WMO, clinical research involving medicinal products must adhere to additional national requirements. The CCMO website provides additional information on these additional requirements (in Dutch).

Clinical trials with medical devices

Clinical trials with medical devices must adhere to both the WMO and the specific legislation for medical devices. See also additional information on this website on clinical research with medical devices.

Parties involved in clinical trials

Different parties may be involved in clinical trials, each with different responsibilities:

  • Sponsor: sponsor/commissioning party. This may be the pharmaceutical industry or a non-commercial institution. For investigator-initiated research, it is the board of directors of the institution.
  • Agent: investigator (specialist, general practitioner, etc.).
  • Third parties: these can be hired by the sponsor. They include contract research organisations (CROs), pharmacies, laboratories and manufacturers of investigational medicinal products.
  • Test subject: the participant in the trial.
