The Pfizer New Haven Clinical Research Unit is conducting a clinical trial of a study drug for non-alcoholic steatohepatitis (NASH), a type of liver disease. This study will look at the effects of the study drug at different doses and when taken with and without food.

NASH is a serious, progressive liver disease caused by a buildup of fat in the liver, resulting in inflammation, cell damage, and scarring of the liver. NASH significantly increases morbidity and the risk of complications like heart attack or stroke. There are currently no therapeutic options approved for NASH, but researchers are working hard to develop treatments for the disease.
