Conditions

Non-Alcoholic Fatty Liver Disease (NAFLD)

Brief summary

This study is to assess the effect of PF 05221304 alone, PF 06865571 alone, the co administration of PF 05221304 and PF 06865571, or placebo on whole liver fat in subjects with NAFLD. In addition, this study will evaluate the safety and tolerability of co administration of PF 05221304 and PF 06865571 along with the effects on selected pharmacodynamics (PD)/exploratory parameters, compared to administration of PF 05221304 alone, PF 06865571 alone, and placebo in adults with NAFLD.

Percent Change From Baseline in Whole Liver Proton Density Fat Fraction (PDFF) at Day 42Baseline, Day 42Magnetic resonance imaging proton density fat fraction (MRI-PDFF) technique is an established method that enables quantification of fat content in the liver. It measures the fraction of mobile protons in the liver attributable to fat content and provides whole liver coverage so that fat content can be assessed across 8 Couinaud liver segments. Whole liver PDFF = PDFFs for (Segment I + Segment II + Segment III + Segment IVa + Segment IVb + Segment V + Segment VI + Segment VII + Segment VIII) divided by total number of segments assessed.
