About this study
Official title: A PHASE 2, RANDOMIZED, DOUBLE-BLIND, DOUBLE-DUMMY, PLACEBO-CONTROLLED, DOSE-RANGING, DOSE-FINDING, PARALLEL GROUP STUDY TO ASSESS EFFICACY AND SAFETY OF PF-06865571 (DGAT2I) ALONE AND WHEN COADMINISTERED WITH PF-05221304 (ACCI) IN ADULT PARTICIPANTS WITH BIOPSY-CONFIRMED NONALCOHOLIC STEATOHEPATITIS AND FIBROSIS STAGE 2 OR 3
The study aims to evaluate two, orally administered, investigational agents - PF-06865571 (DGAT2 inhibitor) and the coadministration of PF-06865571 with PF-05221304 (ACC inhibitor). This study is specifically designed to evaluate the effect of a range of doses of DGAT2i alone, and DGAT2i + ACCi, on resolution of NASH or improvement in liver fibrosis, as assessed histologically (via liver biopsy).
- Being tested
- Placebo, PF-06865571, PF-05221304

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Proportion of Participants Achieving Resolution of NASH Without Worsening/Improvement of Fibrosis by >=1 Stage Without Worsening of NASH/Both Based on Assessment by Sponsor-Identified Central Pathologist at Week 48:Bayesian Dose Response Model (BDRM)
NASH resolution: disappearance of ballooning (Nonalcoholic Fatty Liver Disease [NAFLD] Activity Score [NAS] ballooning score=0;0=no ballooning,1=few balloon cells,2=many cells with prominent ballooning; higher scores(HS)=more disease activity [DA]),residual/no lobular inflammation(NAS lobular inflammation score 0/1,0=no foci,1= <2 foci, 2=2-4 foci,3= >4 foci; HS=more DA),NAS steatosis score 0,1,2,3; 0= <5% hepatocytes involved (HI),1=5-33% HI ,2= 34-66% HI, 3= >66% HI; HS=more DA. No worsening of fibrosis: no change/decrease of at least 1 stage in Brunt-Kleiner scale (BKS) compared to baseline (CTB). Improvement in fibrosis by >=1 stage: decrease of at least 1 stage in BKS CTB. No worsening of NASH: no change/increase in NAS for ballooning, inflammation, steatosis CTB. BDRM utilized to characterize dose response across BID treatment groups, estimate posterior mean proportion (\& 90% credible interval [CI], indicated as 'confidence interval' below) for placebo and each BID dose studied.
Measured: Week 48

Resolution of NASH: disappearance of ballooning (NAS ballooning score= 0; where 0= no ballooning, 1= few balloon cells, 2= many cells with prominent ballooning; higher scores= more disease activity), residual or no lobular inflammation (NAS lobular inflammation score 0 or 1, where 0= no foci, 1= <2 foci, 2= 2-4 foci, 3= >4 foci; higher scores= more disease activity), NAS steatosis score 0, 1, 2, or 3, where 0= <5% hepatocytes involved, 1= 5-33% hepatocytes involved, 2= 34-66% hepatocytes involved, 3= >66% hepatocytes involved; higher scores= more disease activity. No worsening of fibrosis: no change or decrease of at least 1 stage in BKS compared to baseline. Improvement in fibrosis by >=1 stage: decrease of at least 1 stage in BKS compared to baseline. No worsening of NASH: no change or increase in NAS for ballooning, inflammation, steatosis compared to baseline.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study aims to evaluate two, orally administered, investigational agents - PF-06865571 (DGAT2 inhibitor) and the coadministration of PF-06865571 with PF-05221304 (ACC inhibitor). This study is specifically designed to evaluate the effect of a range of doses of DGAT2i alone, and DGAT2i + ACCi, on resolution of NASH or improvement in liver fibrosis, as assessed histologically (via liver biopsy).
