What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a medication called MGL-3196 to see if it can help treat patients with NASH and liver fibrosis. The medication works by reducing fat and inflammation in the liver, which can help heal and protect it from further damage.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on GLP-1 agonists, high dose Vitamin E, or pioglitazone, you must be on a stable dose for 24 weeks before the biopsy.

Is Resmetirom safe for humans?

Resmetirom has been tested in several studies for nonalcoholic fatty liver disease and nonalcoholic steatohepatitis (NASH), and it was generally found to be safe and well tolerated. Some patients experienced mild side effects like diarrhea and nausea, but these were not serious. ^{1 2 3 4 5}

How is the drug Resmetirom unique for treating fatty liver disease?

Resmetirom is unique because it is an orally administered drug that specifically targets the liver and works by activating thyroid hormone receptors to increase fat metabolism and reduce liver fat, which is different from other treatments that may not target these specific pathways. ^{1 2 3 4 6}

What data supports the effectiveness of the drug Resmetirom for treating fatty liver disease?

Research shows that Resmetirom can significantly reduce liver fat and improve liver health in patients with nonalcoholic steatohepatitis (NASH), a type of fatty liver disease. It also helps lower bad cholesterol and triglycerides, which are fats in the blood, making it a promising treatment option. ^{1 2 3 4 5}

They must have metabolic risk factors, an AST level above 20 U/L, and evidence of increased liver fat via MRI-PDFF or a biopsy showing NASH within the last 24 weeks. Participants should not have had significant weight changes recently.

Published Research Related to This Trial

In a 36-week study involving 125 patients with biopsy-confirmed NASH, resmetirom significantly reduced hepatic fat compared to placebo, with a 32.9% reduction at 12 weeks and 37.3% at 36 weeks, indicating its efficacy in treating NASH.

The treatment was generally safe, with most adverse events being mild or moderate; however, there was a higher incidence of mild diarrhea and nausea in patients taking resmetirom.

In a 52-week phase 3 trial involving 1,143 adults with presumed NASH, resmetirom was found to be safe and well tolerated, with treatment-emergent adverse events occurring in similar rates compared to placebo.

Resmetirom significantly reduced hepatic fat, LDL-C, apoB, and triglycerides, indicating its potential efficacy in treating nonalcoholic steatohepatitis and supporting further clinical development.

In a 36-week study, resmetirom significantly reduced liver fat by an average of 11.1% and showed a 52.3% relative reduction in patients with nonalcoholic steatohepatitis (NASH), indicating its efficacy in treating this condition.

Resmetirom also led to significant reductions in LDL cholesterol, apolipoprotein B, and triglycerides, while markers of liver fibrosis decreased, demonstrating both its safety and potential benefits for liver health.

Effects of Resmetirom on Noninvasive Endpoints in a 36-Week Phase 2 Active Treatment Extension Study in Patients With NASH. Harrison, SA., Bashir, M., Moussa, SE., et al.[2023]

Resmetirom effectively reduces lipid accumulation and triglyceride levels in both in vitro NASH cell models and in vivo NASH mouse models, indicating its potential as a treatment for non-alcoholic steatohepatitis (NASH).

The mechanism of action involves the recovery of RGS5 expression and the inhibition of the STAT3 and NF-κB signaling pathways, which are activated in NASH, suggesting that resmetirom targets specific molecular pathways to improve liver health.

Resmetirom Ameliorates NASH-Model Mice by Suppressing STAT3 and NF-κB Signaling Pathways in an RGS5-Dependent Manner. Wang, X., Wang, L., Geng, L., et al.[2023]

Resmetirom (MGL-3196) is a promising treatment for nonalcoholic steatohepatitis (NASH) that has shown potential cost-effectiveness, with an incremental cost-effectiveness ratio of $53,929 per quality-adjusted life-year (QALY) gained, based on a model informed by a phase II clinical trial.

The use of resmetirom could significantly reduce serious liver-related complications, such as decompensated cirrhosis, hepatocellular carcinoma, and the need for liver transplants, indicating its efficacy in improving long-term health outcomes for patients with NASH.

In a Phase 2 trial, resmetirom significantly reduced liver fat and resolved non-alcoholic steatohepatitis (NASH) without worsening fibrosis, indicating its potential efficacy as a treatment for this condition.

The ongoing Phase 3 MAESTRO clinical program aims to further evaluate resmetirom's safety and effectiveness in up to 2000 adults with NASH, using liver biopsies and non-invasive tests to assess outcomes over a 54-week period.
