Completed Clinical Trials

In its completed stage, the study has concluded normally and participants are no longer being examined or treated. This indicates the last patient's final visit has occurred. To protect the safety of patients during trials, though, the same ethical and legal codes which govern the medical practice apply to the trial. Furthermore, most clinical research is federally regulated with participant protections provided by various safeguards. Benefits of participating in a clinical trial include the following:
  • Patient ability to take an active role in their own health care
  • Patient access to new research treatments before available elsewhere
  • Patient access to high quality medical care at leading health care facilities during the trial
  • Patient contribution to medical research for others
Nevertheless, those who completed participation in a clinical trial do face a number of risks, including the following:
  • Experimental treatment showed no effectiveness in the patient
  • Patients were forced to devote significant amounts of time and attention, including study site trips, additional treatments, hospital stays, or complex dosage requirements
  • Patient exhibition of adverse, sometimes life-threatening side effects to the experimental treatment
