A clinical trial is a research study conducted with human beings to see if a new medical device, medication or other treatment is effective and safe. Some study participants will be assigned to a “control arm” or “control group” in the study.
Those who are in the control arm will not receive the new medication, device or treatment that is under study, to provide a comparison to see how the innovation compares against no treatment or an old treatment. Members of the control group may receive a placebo, an inactive treatment such as a pill that makes the group think they are receiving the new treatment.
