About being a study patient

What should I expect as a Study Patient?

  • Participation is confidential. We do not share personal patient information from our database with any outside individuals or companies without your consent
  • Participation is always voluntary and participants can choose to withdraw from a study at any time.
  • Subject safety and well being is a primary concern. An accurate and complete medical history is required to ensure safety as well as to determine if the person is an appropriate study match.
  • Participation in a clinical trial is based on inclusion/exclusion criteria. Some studies require a person to have a specific condition with specific symptoms, while others are for healthy individuals interested in preventive care.
  • Length of participation varies. Some studies may last 4 weeks while others can last up to 3 years. Participation in clinical trials is limited to one study at a time with at least 30 days between each study.
  • Study opportunities may vary each week. You may not qualify for a particular currently enrolling study. However, the following week there may be a similar study (or in the future) with different eligibility criteria.
