The Pfizer Clinical Research Unit is seeking healthy Japanese volunteers for upcoming studies. Japanese participants help our treatments reach Japanese patients around the world faster and truly make a difference as we strive for breakthroughs. 

Healthy volunteers in clinical trials help us understand how a study drug affects the body. This is one way to assess a study drug’s safety before giving it to those who have a medical condition.

If you’re interested in participating in one of our studies, call us or complete our contact form below. We look forward to hearing from you!
