A Study To Assess Pharmacodynamics, Safety And Tolerability Of PF-05221304 And PF-06865571 Co-Administered For 6 Weeks In Adults With Non-Alcoholic Fatty Liver Disease.
A Study To Assess Pharmacodynamics, Safety And Tolerability Of PF-05221304 And PF-06865571 Co-Administered For 6 Weeks In Adults With Non-Alcoholic Fatty Liver Disease.
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.
