Clinical Trials Scholarly Journal

  Clinical trials are experimental observations done in clinical research. Such prospective biomedical or behavioral research investigation on human participants are arranged to answer specific questions about biomedical or behavioral interventions, including innovative treatments. Some clinical trials concern healthy subjects with no pre-existing medical conditions. Other clinical trials relate to patients with distict health conditions who are willing to try an experimental treatment. When participants are healthy volunteers who receive financial incentives, the goals are different than when the participants are sick. During dosing periods, study subjects typically remain under supervision for one to 40 nights. Prices for clinical trials can optimum into the billions of dollars per approved drug. The sponsor could also be a governmental organization or a pharmaceutical, biotechnology or medical device company. Clinical trials are specified basically by the research objective created by the investigators: In an observational study, the investigators observe the themes and measure their outcomes. The researchers do not actively manage the study.   In an interventional study, the investigators give the research subjects an experimental drug, surgical procedure, use of a medical device, diagnostic or other intervention to compare the treated subjects with those receiving no treatment or the standard treatment. Then the researchers assess how the subjects' health changes.
