How can I, as a patient, participate in a clinical study?

Your doctor suggests you participate.Your doctor may suggest that you participate in a clinical trial if he or she suspects that you might be interested. The decision to participate or not is entirely up to you and you have the right to refuse this offer. Whatever decision you make will not affect the quality of your future treatment.
You can also ask your doctor to help you find a clinical trial that is right for you.What if your doctor doesn’t offer you a clinical trial even though you want to participate? You can ask if there are any ongoing clinical trials for your condition and your doctor can help you find an appropriate registered trial. If no trial is available locally, you can also ask if you can participate in a trial in another country. Don’t hesitate to contact your health insurance company, patient associations or other support organizations to find out what options are available to you as they may vary from country to country.

You search for a clinical study yourself.You can also search for clinical trials yourself. You can do this very easily by using the tool on this website.
