What is being measured

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

  1. Relative Change From Baseline in MRI-PDFF at Week 12 for TERN-501 Monotherapy (Arms 1, 2 and 3) Compared to Placebo.

    Magnetic Resonance Imaging Proton Density Fat Fraction (MRI-PDFF) is a non-invasive imaging technique that measures fat content in tissue, particularly in the liver. Relative change from baseline is calculated for each subject as 100 x [(Week 12 Value - Baseline Value)/Baseline Value].

    Measured: 12 weeks

Secondary outcomes (4)
  1. Change From Baseline in cT1 Relaxation Time at Week 12 for TERN-501 Monotherapy (Arms 1, 2 and 3) Compared to Placebo

    Corrected T1 (cT1) is a quantitative MRI relaxation parameter that measures liver inflammation and fibrosis. Change from baseline is calculated for each subject as (Week 12 Value - Baseline Value).

    Measured: 12 weeks

  2. Relative Change From Baseline in MRI-PDFF at Week 12 for TERN-501+TERN-101 Combination (Arms 4 and 5) Compared to Placebo

    Magnetic Resonance Imaging Proton Density Fat Fraction (MRI-PDFF) is a non-invasive imaging technique that measures fat content in tissue, particularly in the liver. Relative change from baseline is calculated for each subject as 100 x [(Week 12 Value - Baseline Value)/Baseline Value].

    Measured: 12 weeks

  3. Change From Baseline in cT1 Relaxation Time at Week 12 for TERN-501+TERN-101 Combination (Arms 4 and 5) Compared to Placebo

    Corrected T1 (cT1) is a quantitative MRI relaxation parameter that measures liver inflammation and fibrosis. Change from baseline is calculated for each subject as (Week 12 Value - Baseline Value).

    Measured: 12 weeks

  4. Number and Percentage of Participants With Any Treatment Emergent Adverse Event for All Treatment Groups (Threshold of 0%)

    This outcome measures the number and percentage of participants with any Treatment Emergent Adverse Event (TEAE) for All Treatment Groups (0% Threshold). TEAEs by System Organ Class and Preferred Term meeting the 5% Threshold are reported in the Other Adverse Events section.

    Measured: 16 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TERN-501 and TERN-101 in people with NASH - Nonalcoholic Steatohepatitis, run by Terns, Inc., a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA) at 35 sites in United States.

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 11 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 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 35 sites in United States. 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?

Yes. Results are posted in the registry (first posted 12 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Relative Change From Baseline in MRI-PDFF at Week 12 for TERN-501 Monotherapy (Arms 1, 2 and 3) Compared to Placebo. (time frame: 12 weeks). 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 NCT05415722, which also lists 1 linked publication.

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 Mar 2025.
