What Are the Costs of Participating in a Clinical Trial?

In some cases, taking part in a trial will not cost you or your insurance company anything. In other studies, the research team may bill your insurance company for drugs, devices, and services they provide. It is possible that your insurance company will not pay for some or all of the charges and you may receive a bill for those costs. The informed consent form will describe any costs to you in detail. If the information in the consent form is not clear, you may ask a member of the research team to explain any potential costs to you before signing the consent form.
