Background: Obesity is a complex disease associated with multiple concurrent complications, and the coordinated targeting of multiple pathways in pharmacological treatment may improve weight loss outcomes. During synthesis, ghrelin is converted from the 'inactive' unacylated ghrelin (UAG) to the active acylated ghrelin (AG) by the enzyme ghrelin-O-acyltransferase (GOAT), stimulating appetite and food intake.
Aims: To report the results of two Phase I studies investigating single rising doses (SRDs) or multiple rising doses (MRDs) of the novel oral GOAT inhibitor BI 1356225 versus placebo in male and postmenopausal/sterilised female subjects with overweight or obesity.
