Summary of "Novel MRI assessment of treatment response in HIV-associated NAFLD: a randomized trial of an SCD1 inhibitor (ARRIVE Trial)."

Aramchol, an oral stearoyl-coenzyme-A-desaturase-1 (SCD1) inhibitor, has been shown to reduce hepatic-fat content in patients with primary nonalcoholic-fatty-liver-disease (NAFLD), however, its effect in patients with HIV-associated NAFLD is unknown. The ARRIVE trial was a double-blind, randomized, investigator-initiated, placebo-controlled trial to test the efficacy of 12 weeks of treatment with aramchol versus placebo in HIV-associated NAFLD. Fifty patients with HIV-associated NAFLD, defined by MRI-proton-density-fat-fraction (PDFF) ≥5%, were randomized to receive either aramchol 600 mg daily (n=25) or placebo (n=25) for 12 weeks. The primary endpoint was a change in hepatic-fat as measured by MRI-PDFF in co-localized regions-of-interest. Secondary endpoints included changes in liver-stiffness using MR-elastography (MRE) and vibration-controlled-transient-elastography (VCTE) and exploratory endpoints included changes in total body fat and muscle depots on DXA, whole-body and cardiac MRI. The mean (±SD) of age and BMI were 48.2±10.3 years and 30.7±4.6kg/m respectively. There was no difference in the reduction in mean MRI-PDFF between the aramchol group at -1.3% (baseline-MRI-

There were no differences in MRE and VCTE derived liver-stiffness, and whole body (fat and muscle) composition analysis by MRI or DXA. Compared to baseline, end-of-treatment aminotransferases were lower in the aramchol group but not in the placebo arm. There were no significant adverse events.
CONCLUSION:
Aramchol, over a 12-week period, did not reduce hepatic-fat or change body fat and muscle composition by utilizing novel MRI-based assessment in patients with HIV-associated NAFLD. This article is protected by copyright. All rights reserved.

Medical and Biotech [MESH] Definitions

Work consisting of a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.

Work consisting of a clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.

Trial that aims to show a new treatment is no better and no worse than the standard treatment.

A scale comprising 18 symptom constructs chosen to represent relatively independent dimensions of manifest psychopathology. The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses. (From Hersen, M. and Bellack, A.S., Dictionary of Behavioral Assessment Techniques, p. 87)

Works about randomized clinical trials that compare interventions in clinical settings and which look at a range of effectiveness outcomes and impacts.
