A clinical trial is a research study conducted with people.
Clinical trials are the primary method of advancing medical knowledge.
This board, which includes consumers, clergy, and health professionals, reviews the protocol to be sure that the research will not expose participants to inappropriate risks. In PLCO, there is an independent monitoring and advisory panel that continues to monitor the study to ensure the safety of the participants. People from all parts of the country and of all ages and ethnic backgrounds volunteer to take part in clinical studies. Before they begin the study, participants are given all the facts about the study including possible risks. This process is called informed consent.
