A Research Study of a Potential New Medicine (NNC4005-0001) for Liver Disease in Adult Participants With Increased Body Weight and Liver Fat

February 9, 2026 updated by: Novo Nordisk A/S

A Randomized, Double-blind, Placebo-controlled, Single Ascending Dose, First-in-human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of NNC4005-0001 in Adults

The purpose of this clinical study is to find out if NNC4005-0001 is well-tolerated and safe for people who have increased body weight and increased liver fat. Participants will receive either NNC4005-0001, which is the treatment being tested, or a placebo, which is a treatment that contains no active medicine. The study will last for about for about 7 to 8 months.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Aged 18-69 years (both inclusive) at the time of signing the informed consent.
  • Body Mass Index (BMI) of 27.0-40.0 kilogram per square meter (kg/m^2) (both inclusive) at screening process.
  • Hepatic fat fraction greater than or equal to (≥) 8% by magnetic resonance imaging proton density fat fraction (MRI-PDFF) within 17 days prior to dosing.
  • No prior or present clinical history of metabolic dysfunction-associated steatohepatitis (MASH) diagnosis.

Exclusion criteria:

  • Any condition, which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol.
  • Previous or current use of therapies for MASH or antifibrotic therapies (authorised or within aclinical trial).
  • Use of high-dose vitamin E [greater than (>) 800 international unit (IU) per day], glucagon-like peptide-1 (GLP-1) agonists (such as liraglutide, dulaglutide, or semaglutide), glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 agonists (such as tirzepatide), or pioglitazone within 6 months prior to screening.
  • Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) levels greater than or equal (≥) 1.5× Upper Limit of Normal (ULN) at screening.
  • Total bilirubin levels > 1.5 times ULN if direct bilirubin is within Normal Limits (WNL) at screening.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
