What Is a Clinical Trial?

A clinical trial is a carefully designed research study that tests whether a new medication, device or treatment approach is safe and effective. Each trial follows a detailed plan, called a protocol, that explains who can join, what happens at each visit and how the results will be measured.

The Four Phases of Clinical Research

  • Phase 1: a small group of participants, often healthy volunteers, helps researchers understand safety and how the body processes a new medicine.
  • Phase 2: the treatment is studied in people with the condition to look at effectiveness and side effects.
  • Phase 3: larger studies compare the new treatment with a placebo or with current treatments; these results support FDA review.
  • Phase 4: after approval, studies continue to follow long-term safety and effectiveness.

How Participants Are Protected

Every study is reviewed by an independent ethics board, called an Institutional Review Board (IRB), before it begins. Before you join, the study team walks you through an informed consent document that explains the purpose, procedures, possible risks and benefits. Participation is always voluntary, and you can leave a study at any time.

Frequently Asked Questions

Will I receive a placebo?

Some studies compare a new treatment with a placebo, and others do not. The study team will always tell you before you agree whether a placebo is used and what that means for you.

Does it cost anything to participate?

Study-related visits and investigational treatment are typically provided at no cost, and some studies compensate participants for their time and travel. The details are explained during the consent process.

Can I keep seeing my own doctor?

Yes. Participating in a study does not replace your regular care, and the research team can coordinate with your doctors when needed.
