Active, Not Recruiting Clinical Trials

In trials which are active, not recruiting, the study is ongoing, though enrollment has completed. Participants in this stage of a trial are treated or examined and no new patients are being added. During an active trial, patients must continue to be shown the key facts of the trial, as they did before the trial began. This disclosure helped them decide whether to participate or not. This is known as informed consent. Patients in active trials have the opportunity to withdraw at any point, though they must notify the research team and explain their reasons. Failing to do so could skew the results. During active clinical trials, especially with experimental treatments, these new drugs and procedures are often compared to placebo medications. Placebos are inactive pills, liquids or powders which have no treatment value and act as a study control. There are even a number of different clinical trial types that may be performed. These include the following:
  • Treatment trials, where experimental treatments, new drugs, new procedures or combinations of all are tested
  • Prevention trials, which seek improved ways of preventing disease and may include medication, vaccines, vitamins, minerals or even lifestyle changes
  • Diagnostic trials attempt to uncover better tests or procedures to diagnose particular conditions or diseases
  • Screening trials test the best way to detect certain health conditions or diseases
  • Quality of life trials, also known as supportive care trials, explore ways to improve the comfort and quality of life for those with an illness
