Clinical trials have led to life-changing new medicines, and we thank everybody who has participated and made a contribution. Today, more than 100,000 people around the world are participating in Pfizer clinical trials. We are grateful to those who are already taking part, and to all those who will participate in the future. 

Whether you have a specific condition in mind, or you’re just interested in seeing the types of clinical trials we’re conducting, we invite you to explore our areas of research here.

Our center for clinical research

It takes dedicated people to develop medicines that will change lives. Some of these people are ‘healthy volunteers,’ participants who don’t have the disease or condition that will later be studied. Learn more about the vital role that healthy volunteers play in our phase 1 clinical trials, and about the research facility where many of these trials take place.
