Why participate?

For starters, in 2017, 94% of people who participated in a clinical trial said they would participate in another one in the future.1

We like that number!

All clinical trials have risks involved since the safety and efficacy of the investigational drug being tested have not yet been proven. However, there are many potential benefits in choosing to be part of a study. Millions of people in the United States participate in trials each year, and they do so for a variety of reasons.

What might it be like to participate in a clinical trial?



Participation in a clinical trial can also help other people get new treatments sooner. Without clinical trials and their participants, the development of these treatments would not be possible. To better understand what it might be like to be in a clinical trial, let’s hear from a few people on their personal experience when they participated in a clinical trial.


How a trial works

Clinical trials are broken down into smaller steps from beginning to end, called phases. 

One phase cannot conclude until it meets all of its objectives.

Examples of phases include: 

Phase one

Phase 1

The initial study of an investigational drug in a small group of participants (about 20-80 people) to learn about its safety.

Phase two

Phase 2

Continues to evaluate safety by testing the drug on a bigger group of participants (about 100-300 people).

Phase Three

Phase 3

Looks to confirm the safety and effectiveness in a greater group of participants (about 1000-3000 people), often in comparison to existing treatment.
