Clinical trials are used to look for new drugs or combination of drugs, new ways of giving the drugs to patients, new types of surgery, new devices, or new treatments. Clinical trials must be done before a new drug, treatment, or device is allowed to be used in hospitals or clinics. The group of people in a country’s government that watch over research is called a regulatory agency. The regulatory agency in the European Union is the European Medicines Agency (EMA). The EMA decides if and how doctors and scientists (Investigators) test a new drug, treatment or device.
Hospitals running clinical trials have groups of people that review all trials at that hospital, called Ethics Committees (EC), to make sure that all participants in the trials are safe. The EC includes scientists, healthcare providers, and people in the community. The EC reviews, approves, and watches over all research for humans in that hospital; to make sure the rights of trial volunteers are protected. This is the law.
The EC review makes the trials as safe as possible but there are always still some risks. When the trials are for people who are very sick, the risks are usually higher. With all trials, information will be given about ways that the treatment might be helpful or harmful. This information is part of the “informed consent form” (ICF). The ICF will be reviewed with you by the trial doctor (Investigator), in your native language, to help you to decide to volunteer for the trial or not. The ICF will also tell you how to let the Investigator know if you think you are having a problem during the trial. You should ask any questions you may have about a clinical trial before signing the ICF. Even after you have signed the ICF to volunteer in a clinical trial, you can always speak to the Investigator or any trial team member, at any time during the trial, if you have more questions or problems.
Also, there is a Data Safety Monitoring Board (DSMB) which is another group of people made up of doctors and other scientists not involved in the trial. The job of the DSMB is to look at and watch over the trial safety results. In case they believe that you might be harmed, they can stop the trial any time if:
- The new trial treatment might be more harmful than helpful.
- The results show that the new treatment is much better (or much worse), so that all trial volunteers get the better treatment.
