About this study

Official title: A Phase 2b Randomized, Double-Blind, Placebo-Controlled, Multicenter Study to Evaluate the Efficacy and Safety of Efinopegdutide (MK-6024) in Adults With Precirrhotic Nonalcoholic Steatohepatitis

The purpose of this study is to learn how well efinopegdutide works compared to placebo in people who have non-alcoholic steatohepatitis (NASH). Researchers will also learn about the safety and benefit of efinopegdutide and how well people tolerate the medicine. The main goal of the study is to compare how many people taking efinopegdutide or placebo stop showing evidence of NASH without liver scarring getting worse.

Being tested
Efinopegdutide, Semaglutide, Placebo

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Nonalcoholic Steatohepatitis (NASH) Resolution Without Worsening of Fibrosis At Week 52

    The NASH Clinical Research Network (CRN) scoring system evaluated by Blinded Independent Central Review (BICR) is used to assess treatment response. The NASH CRN scoring scales are: lobular inflammation score (0-3); hepatocyte ballooning score (0-2); steatosis score (0-3); and fibrosis score (0-4). NASH resolution is defined as a score of 0-1 for inflammation, 0 for ballooning, and any grade of steatosis.

    Measured: Week 52

  2. Percentage of Participants Who Experienced an Adverse Event (AE)

    An adverse event (AE) is a health problem that happens or worsens during a study.

    Measured: Up to 60 weeks

  3. Percentage of Participants Discontinuing Study Medication Due to an AE

    An adverse event (AE) is a health problem that happens or worsens during a study.

    Measured: Up to 52 weeks

Secondary outcomes (2)

  1. Percentage of Participants With ≥1 Stage Improvement in Fibrosis Without Worsening of Steatohepatitis At Week 52

    Participants will be assessed using the NASH CRN scoring system evaluated by BICR for ≥1-stage improvement in fibrosis without worsening of steatohepatitis. Fibrosis is scored from stage 0 to 4 where 0 = None, 1=Perisinusoidal OR periportal, 2=Perisinusoidal AND portal/periportal, 3= Bridging fibrosis, 4=Cirrhosis. No worsening of steatohepatitis is defined as no increase in the ballooning, inflammation, or steatosis scores.

    Measured: Week 52

  2. Change from Baseline in Body Weight At Week 52

    Body weight (kg) will be measured using a standardized, digital scale. The percent change from baseline in body weight after 52 weeks will be reported.

    Measured: Week 52

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Efinopegdutide and Semaglutide in people with Non-alcoholic Fatty Liver Disease and Fatty Liver, Nonalcoholic, run by Merck Sharp & Dohme LLC at 175 sites in 26 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 3 inclusion and 6 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: finished, as of the sponsor's last update on 12 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 175 sites in United States, Japan, France, Spain, China and 21 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 With Nonalcoholic Steatohepatitis (NASH) Resolution Without Worsening of Fibrosis At Week 52 (time frame: Week 52). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05877547.

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 12 Jan 2026; AzTrials last refreshed its copy on 8 Nov 2026.
