The Informed patient consent is a key part of a good trial and is required in studies that are federally regulated as well as, by many state laws. Informed consent means that a patient, you are given information so you can understand what is involved in a trial, including its potential benefits and risks, and then decide freely whether or not to take part in the trial. The nature of the treatment is explained by the doctors and nurses in the trial. You are given an informed consent form to read and consider carefully. You should feel free to ask any questions you may have regarding any aspect of the trial. Then, if you agree to take part, you will sign the form giving your consent to participate. As always, you may also decide not to sign the consent, therefore deciding not to participate. The informed consent is an ongoing process. If you enter a trial, you will continue to receive any new information about your treatment that may affect your willingness to stay in the trial. Signing a consent form does not bind you to the study. You always have the option to leave the study at any time.
