Clinical Trials

Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research.

ClinicalTrials.gov provides regularly updated information about federally and privately supported clinical research in human volunteers.

ClinicalTrials.gov gives you information about a trial's purpose, who may participate, locations, and phone numbers for more details.

The benefits and risks of participating in a clinical trial


Benefits


Clinical trials that are well-designed and well-executed are the best approach for eligible participants to:

  • Play an active role in their own health care.
  • Gain access to new research treatments before they are widely available.
  • Obtain expert medical care at leading health care facilities during the trial.
  • Help others by contributing to medical research.

Risks


There are risks to clinical trials.

  • There may be unpleasant, serious or even life-threatening side effects to experimental treatment.
  • The experimental treatment may not be effective for the participant.
  • The protocol may require more of their time and attention than would a non-protocol treatment, including trips to the study site, more treatments, hospital stays or complex dosage requirements.
