Clinical trials are a type of scientific study that tests how well medical treatments and procedures work in human health. The goal of clinical trials is to improve the diagnosis and treatments of patients and to improve the health of individuals participating in the trials. Clinical trials help determine the safety and efficacy of medications, vaccines, diagnostic products and medical devices to all types of disease.
An informed consent form provides patients with important information about the clinical trial before they decide to participate in the trial, including the procedures that they will undergo and possible risk and benefits. Participation in any trial is voluntary.
