As much as we would like to give everyone the opportunity to participate in a study, a person’s medical history may prohibit this from happening. Our first and foremost intention is for the well being of the patient. To participate in drug trial, an individual must first be diagnosed with the condition for which the trial is being conducted. This is can be done in one of two ways. They can either have their personal physician submit their records to the clinic for review, or have the clinic perform a physical examination and diagnosis. The content of the physical examination is totally dependent on the clinical drug trial. Once it has been determined that a person can be a participant in a clinical trial, he or she will then be asked to sign an informed consent form. This informs the participant about the guidelines and procedures they will need to follow during the study. Also, it informs the participant of the possible side effects that may occur from taking the study medication. After signing the informed consent form the individual is then placed in a study.
