The primary endpoint in both studies was percent change from baseline in liver fat assessed by magnetic resonance imaging–proton density fat fraction. The first study ( NCT03248882) examined the effects of monotherapy with a novel ACC1/2 inhibitor, PF-05221304 (2, 10, 25 and 50 mg once daily (QD)), versus placebo at 16 weeks of treatment the second study ( NCT03776175) investigated the effects of PF-05221304 (15 mg twice daily (BID)) co-administered with a DGAT2 inhibitor, PF-06865571 (300 mg BID), versus placebo after 6 weeks of treatment. Two parallel phase 2a studies investigated the effects of liver-directed ACC1/2 inhibition in adults with NAFLD. However, no pharmacological agents are currently approved in the United States or the European Union for the treatment of NAFLD. Alterations in lipid metabolism might contribute to the pathogenesis of non-alcoholic fatty liver disease (NAFLD).
