Informed consent is the process of learning the key facts about a clinical trial before deciding whether to participate. It is also a continuing process throughout the study to provide information for participants. To help someone decide whether to participate, the doctors and nurses involved in the trial explain the details of the study. Then the research team provides an informed consent document that includes details about the study, such as its purpose, duration, required procedures and key contacts. Risks and potential benefits are explained in the informed consent document. The participant then decides whether to sign the document. Informed consent is not a contract, and the participant may withdraw from the trial at any time
