Objectives
The primary objective of this study is to evaluate the effect of **resmetirom** administered orally at a dose of 80 mg daily, compared to a matching placebo, on the time to the first adjudicated Composite Clinical Outcome event in patients with well-compensated Non-alcoholic Steatohepatitis (NASH) Cirrhosis. This outcome is defined by the occurrence of liver-related or cardiovascular mortality, liver transplant, and significant hepatic events, including hepatic decompensation events such as ascites, hepatic encephalopathy, or gastroesophageal variceal hemorrhage, as well as a confirmed increase in the Model for End-stage Liver Disease (MELD) score from less than 12 to 15 or greater. The clinical relevance of this objective lies in its potential to provide insights into the efficacy of resmetirom in delaying or preventing critical liver-related outcomes in this patient population.
Secondary objectives include:
- Percent change from baseline to week 28 in low-density lipoprotein cholesterol (LDL-C).
- Percent change from baseline to week 52 in hepatic fat fraction, as measured by magnetic resonance imaging proton density fat fraction (MRI-PDFF), in patients with a baseline MRI-PDFF greater than 5%.
Participants
The clinical trial involves a total of **697 participants** diagnosed with **Non-alcoholic Steatohepatitis (NASH) Cirrhosis**. The study population includes both male and female adults aged **18 years and older**. Participants were selected based on specific inclusion criteria, including a definitive or probable diagnosis of NASH as the causative agent for cirrhosis, and a well-compensated Child-Pugh A cirrhosis status. The trial population is characterized by a diverse range of individuals, including those considered vulnerable. Participants are required to adhere to specific lifestyle considerations, such as the use of effective birth control methods for those of reproductive potential. The selection process ensures that participants have no history of hepatic decompensation events, maintaining a focus on individuals with stable health conditions related to their liver disease. The trial does not provide additional information regarding specific lifestyle habits such as diet or physical activity.
Plans and Procedures
The clinical trial is designed to evaluate the effect of **resmetirom** on liver-related outcomes in patients with well-compensated non-alcoholic steatohepatitis (NASH) cirrhosis. This is a randomized, double-blind, placebo-controlled Phase 3 study. Participants will be randomly assigned to receive either 80 mg of resmetirom or a matching placebo, administered orally once daily. The primary endpoint is the time to a confirmed adjudicated composite clinical outcome event, which includes liver-related or cardiovascular mortality, liver transplant, significant hepatic events, and a confirmed increase in the Model for End-stage Liver Disease (MELD) score from less than 12 to 15 or more.
The trial is expected to last until June 2026, with participant involvement spanning up to 36 months. The study will commence with an inclusion (screening) visit to assess eligibility based on criteria such as age, reproductive status, and definitive or probable NASH as the causative agent for cirrhosis. Participants must have well-compensated Child-Pugh A cirrhosis and no history of hepatic decompensation events. Follow-up visits will occur at regular intervals to monitor the participants' health status and adherence to the study protocol. The end-of-study visit will conclude the trial for each participant, assessing the final outcomes and any adverse events.
Participants may be withdrawn from the study if they experience significant adverse effects, fail to adhere to the study protocol, or if the investigator deems it necessary for their safety. The trial will also include secondary endpoints, such as the percent change from baseline in LDL-C at Week 28 and the percent change in hepatic fat fraction by MRI-PDFF at Week 52 in patients with a baseline MRI-PDFF of 5% or more. The study aims to provide comprehensive data on the efficacy and safety of resmetirom in treating NASH cirrhosis, contributing to the understanding and management of this condition.
Treatment
The clinical trial involves the administration of **MGL-3196**, also known as **resmetirom**, which is a chemical compound provided in the form of a film-coated tablet. The experimental medication is available in three dosages: 60 mg, 80 mg, and 100 mg. Each dosage is administered orally once daily. The maximum daily dose for each variant corresponds to its respective dosage, with a treatment period extending up to 36 months. The active substance, resmetirom, is chemically synthesized and is intended to evaluate its effect on liver-related outcomes in patients with well-compensated non-alcoholic steatohepatitis (NASH) cirrhosis.
In addition to the experimental medication, the study includes the use of matching placebos for each dosage level of MGL-3196. These placebos are also provided as film-coated tablets and are designed to be indistinguishable from the active medication in appearance and administration. The placebo tablets are administered orally once daily, mirroring the dosing schedule of the active treatment. The inclusion of placebos allows for a double-blind study design, ensuring that neither the participants nor the investigators are aware of the treatment assignments, thereby reducing bias and enhancing the reliability of the study outcomes.
Efficacy
Efficacy in this clinical trial will be assessed by evaluating the effect of once-daily, oral administration of **resmetirom** versus a matching placebo in patients with Non-Alcoholic Steatohepatitis (NASH) cirrhosis. The primary endpoint is the time to a confirmed adjudicated Composite Clinical Outcome event. This composite event includes liver-related or cardiovascular mortality, liver transplant, significant hepatic events such as hepatic decompensation events, and a confirmed increase in the Model for End-stage Liver Disease (MELD) score from less than 12 to 15 or greater.
Secondary endpoints include the percent change from baseline in LDL-C at Week 28 and the percent change from baseline to Week 52 in hepatic fat fraction as measured by MRI-PDFF in patients with a baseline MRI-PDFF of 5% or greater. These efficacy parameters will be measured and collected at specified timepoints throughout the trial, ensuring a comprehensive analysis of the treatment's impact on the disease progression and related outcomes.
