Clinical trials of medicinal products

18 June 2019

When a new medicine is to be developed, clinical trials with human participants must be carried out to find out how the medicine works, what side effects it has and how it is metabolised in the body. In this short film, you can hear more about how a medicine passes the tests and reaches consumers.

A clinical trial of medicine takes place in different phases. Phase 1-3 precede the authorisation of the medicine, and phase IV includes trials with known medicines that are already on the Danish market.

The Danish Medicines Agency must authorise the conduct of clinical trials of medicines. The application must be submitted by the organisation or person with overall responsibility for the trial, but it must always be a doctor or a dentist who is in contact with the participants in the trial.

Clinical trials must also be notified to a research ethics committee. The research ethics committee primarily evaluates the ethical aspects of the trial as well as the information that is made available to the trial participants. The research ethics committee must authorise the trial as well.

The participants in a clinical trial of medicines must be healthy volunteers or patient volunteers.

Adverse reactions in clinical trials of medicines

The organisation or person with overall responsibility for the trial must collect adverse reactions occurring in the trial and must regularly report Suspected Unexpected Serious Adverse Reactions (SUSARs). Read more about how to report adverse reactions in clinical trials here.
