An Independent research site dedicated to patients, sponsors, and innovation

All clinical trials are supervised by licensed, highly experienced physicians. These trials typically run for a defined short-term period—ranging from 6 months to 4 years. Every study is rigorously reviewed and approved by the FDA and Arizona Institutional Review Boards (IRBs). If you qualify for participation, you may gain access to innovative treatments that are not yet available to the general public.
