The Center for Neurosciences is Southern Arizona’s largest and longest-standing neuroscience medical practice. Our aim is to deliver the highest standard of neurological care – the same level of care we would want for ourselves or our loved ones. The Center has a dedicated Clinical Research Program with six principal investigators and a full-time research nurse. Collectively, our investigators have vast experience conducting phase II through phase IV clinical trials in a broad range of neurologic diseases affecting adults and children.
Our Clinical Research Program was initiated in January 2009, but our investigators and staff have previously conducted many clinical trials in collaboration with major pharmaceutical companies and contract research organizations. The therapeutic areas that are the focus of our Clinical Research Program include Alzheimer’s, brain tumors, epilepsy, headache/migraine, multiple sclerosis, pain and movement disorders.

With more than 200 patient visits per day, the Center for Neurosciences has an extensive patient base from which to draw. Not only do we serve the metropolitan Tucson area, but also serve smaller communities throughout the state of Arizona through our satellite clinics. We reach approximately 1.5 million people in Southern Arizona.
Our region has a culturally and ethnically diverse patient population that breaks down as follows: 60% Caucasian, 30% Hispanic, 3% African American, 3% Native American, and 3% Asian. Two of our principal investigators and our site director speak fluent Spanish.
The Center for Neurosciences has worked with many central Independent Review Boards (IRBs), including Copernicus, Sterling, Quorum and Schulman. For hospital-based studies, we have experience with the Carondelet Health Network Human Subjects Committee. We offer efficient study start-up. Contracts are typically executed within 30 days of receipt and centralized IRB approvals are obtained within two to three weeks.
