What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - F3 Cohort
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.
Measured: At Week 52
Percentage of Participants Achieving NASH Resolution with no Worsening of Fibrosis - F3 Cohort
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.
Measured: At Week 52
Secondary outcomes (40)
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - Pooled Cohort (F3 participants and F4 participants)
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.
Measured: At Week 52
Percentage of Participants Achieving NASH Resolution with no Worsening of Fibrosis - Pooled Cohort (F3 participants and F4 participants)
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.
Measured: At Week 52
Change from baseline in Pro-peptide of type III collagen (Pro-C3) - F3 Cohort
Measured: Baseline (Day 1) and at Week 24 and 52
Change from baseline in liver fat using Magnetic resonance imaging-proton density fat fraction (MRI-PDFF) - F3 Cohort
Measured: Baseline (Day 1) and at Week 24 and 52
Change from baseline in Liver stiffness measurement (LSM) by Vibration-controlled transient elastography (VCTE) - F3 Cohort
Measured: Baseline (Day 1) and at Week 24 and 52
Change from baseline in Enhanced Liver Fibrosis (ELF) Score - F3 Cohort
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.
Measured: Baseline (Day 1) and at Week 24 and 52

Primary outcome
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - F3 Cohort
Time frame: 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 - F3 Cohort
Time frame: 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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing GSK4532990 in people with Nonalcoholic Fatty Liver Disease and Non-alcoholic Fatty Liver Disease, run by GlaxoSmithKline at 170 sites in 17 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 18 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 170 sites in United States, Japan, India, Spain, Italy and 12 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants Achieving ≥ 1 Stage Improvement in Histological Fibrosis with no Worsening of NASH - F3 Cohort (time frame: At Week 52). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026.
