Non-alcoholic Fatty Liver Disease
Interventions
Drug: Placebo
Registration Number
NCT05583344

Brief Summary

The purpose of this study is to measure improvements in liver fibrosis and inflammation with GSK4532990 compared with placebo in participants with NASH and advanced fibrosis on biopsy (F3 or F4). The study duration will be up to 76 weeks including the screening period. The treatment duration will be up to 52 weeks.

Inclusion Criteria
  • Body Mass Index (BMI) ≥25 kilogram per meter square (kg/m^2) (all ethnic origins) except for Asian participants who qualify for the study with BMI ≥23 kg/m2 at Screening.
  • In the opinion of the investigator, there are features of metabolic syndrome and NAFLD is the most likely cause of liver disease. Metabolic syndrome may include type 2 diabetes mellitus (T2DM), obesity, dyslipidemia and hypertension.
  • A liver biopsy at baseline showing NAFLD Activity Score (NAS) >=4 with at least 1 point each in steatosis, inflammation and ballooning and either Fibrosis 3 or Fibrosis 4 using NASH CRN Scoring System.
  • Able and willing to comply with all study assessments, including a liver biopsy at Week 52.
Exclusion Criteria
  • Current alcohol consumption ≥14 standard drinks (24 units, 196 g ethanol) per week for females or ≥21 standard drinks (37 units, 294g ethanol) per week for males.
  • Weight reduction surgery or procedures (including gastric banding and intragastric balloon insertion) within 2 years of Screening 1 and/or planned during the study.
  • History of cancer within previous 2 years from Screening 1, except basal or squamous cell carcinoma of the skin or in situ cervical carcinoma or any other type of cancer which has been treated medically or surgically with curative outcome.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - F3 CohortAt Week 52

Improvement in histological fibrosis is assessed with Clinical research network (CRN) Scoring. No worsening of NASH is defined as no increase in the NAFLD Activity Score (NAS) for steatosis, ballooning, or inflammation.

Percentage of Participants Achieving NASH Resolution with no Worsening of Fibrosis - F3 CohortAt Week 52

NASH resolution is defined as a ballooning score of 0 and an inflammation score of 0-1. No worsening of fibrosis is defined as no increase in CRN fibrosis score.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - Pooled Cohort (F3 participants and F4 participants)At Week 52

Improvement in histological fibrosis is assessed with Clinical research network (CRN) Scoring. No worsening of NASH is defined as no increase in the NAFLD Activity Score (NAS) for steatosis, ballooning, or inflammation.

Percentage of Participants Achieving NASH Resolution with no Worsening of Fibrosis - Pooled Cohort (F3 participants and F4 participants)At Week 52

NASH resolution is defined as a ballooning score of 0 and an inflammation score of 0-1. No worsening of fibrosis is defined as no increase in CRN fibrosis score.

Change from baseline in Enhanced Liver Fibrosis (ELF) Score - F3 CohortBaseline (Day 1) and at Week 24 and 52

The ELF score will be calculated using a published algorithm combining the values of a set of extracellular matrix markers, including tissue inhibitor of metalloproteinases-1 (TIMP-1), type III procollagen (PIIINP), and hyaluronic acid (HA). The ELF score is used as a prognostic marker for disease progression: ELF score \< 9.8 : Low risk of progression, ELF score 9.8 to \< 11.3 : Moderate risk of progression and ELF score \> = 11.3 : High risk of progression.
