The Pfizer Clinical Research Unit in New Haven is seeking healthy Japanese volunteers for a clinical trial of a study drug for type 2 diabetes. This study will look at the effects of the study drug when taken as an oral suspension and with or without food.

Type 2 diabetes (T2D) is a chronic disease that occurs when a person’s body does not make or use insulin effectively to regulate blood sugar. Rates of T2D have been increasing in Japan over the last several years, and despite the availability of multiple treatments, approximately half of people diagnosed with T2D are not at their blood sugar goal. Pfizer aims to identify and develop breakthrough treatments for people with this disease.
