Trial Outcomes & Findings for DUET Study: A Clinical Study to Evaluate the Safety, Efficacy, Pharmacokinetics and Pharmacodynamics of Orally Administered TERN-501 as Monotherapy and in Combination With TERN-101 in Noncirrhotic Adults With Presumed Non-Alcoholic Steatohepatitis (NCT NCT05415722)

NCT ID: NCT05415722

Last Updated: 2025-03-12

Results Overview

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 \[(Week 12 Value - Baseline Value)/Baseline Value\].

PRIMARY outcome

Timeframe: 12 weeks

Population: Efficacy Analysis Set: All patients who were randomized and received at least 1 dose of the study. Primary analyses were based on observed data, i.e. no imputation was performed for missing data at Week 12. Therefore, the number of patients analyzed at Week 12 may not be the same as the number of patients treated.

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 \[(Week 12 Value - Baseline Value)/Baseline Value\].

Population: Efficacy Analysis Set: All randomized patients who received at least 1 dose of study drug. Primary analyses were based on observed data, i.e. no imputation was performed for missing data at Week 12. Therefore, the number of patients analyzed at Week 12 may not be the same as the number of patients treated.

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).
