Patient Testimonials

“This was a great experience. The study drug proved to be very beneficial for me and was something I would not have had the opportunity to try outside of this study. Lana was AMAZING! Always accessible and responded to any emails very quickly. I really enjoyed working with her on this study and would be glad to do so again if the opportunity arises. Dr. Stacey was also great to work with. It was a very pleasant experience.”
