What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to evaluate the safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of efimosfermin in participants with metabolic dysfunction associated steatohepatitis (MASH) and compensated cirrhosis consistent with stage F4 fibrosis.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is Efimosfermin safe for humans?

Efruxifermin, which is similar to Efimosfermin, has been tested for safety in patients with liver disease, and the trials focused on its safety and tolerability. While specific safety details for Efimosfermin are not provided, similar drugs have been evaluated for safety in clinical trials. ^{1 2 3 4 5}

How does the drug Efimosfermin Alfa differ from other treatments for fatty liver disease?

Efimosfermin Alfa is unique because it is a fibroblast growth factor 21 (FGF21) analog, which means it mimics a protein that helps reduce liver fat and improve liver health. This drug is administered through weekly subcutaneous injections, which is different from many other treatments that may be taken orally. ^{1 2 6 7 8}

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

Research on a similar drug, efruxifermin, which is also a fibroblast growth factor 21 (FGF21) analog, showed it could reduce liver fat in patients with non-alcoholic steatohepatitis (NASH), a type of fatty liver disease. This suggests that Efimosfermin Alfa might also be effective in reducing liver fat in similar conditions. ^{1 2 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-75 with compensated cirrhosis due to metabolic dysfunction associated steatohepatitis (MASH) and stage F4 fibrosis. Participants must have at least two components of metabolic syndrome and be able to give informed consent. Those with type 1 diabetes, other causes of chronic liver disease, or decompensated liver disease cannot join.

Inclusion Criteria

I have at least two symptoms of metabolic syndrome.

Other inclusion criteria may apply.

My liver biopsy shows stage F4 fibrosis.

Exclusion Criteria

I have a history of type 1 diabetes.

I have chronic liver disease but no history of severe liver failure.

Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥5 × the upper limit of normal (ULN)

What Are the Treatments Tested in This Trial?

Interventions

• Efimosfermin Alfa

Trial Overview The study tests the safety and potential benefits of Efimosfermin Alfa in individuals with MASH-related cirrhosis. It compares this new treatment against a placebo while also studying how the body processes the drug.

How Is the Trial Designed?

Group I: Efimosfermin (Dose 2) Experimental Treatment 1 Intervention

Participants will receive efimosfermin (Dose 2) Q4W.

Group II: Efimosfermin (Dose 1) Experimental Treatment 1 Intervention

Participants will receive efimosfermin (Dose 1) once every 4 weeks (Q4W).

Group III: Placebo Placebo Group 1 Intervention

Participants will receive placebo Q4W.

Published Research Related to This Trial

Efruxifermin was found to be safe and well-tolerated in a study of 30 patients with compensated NASH cirrhosis, with most adverse events being mild to moderate gastrointestinal issues.

After 16 weeks of treatment, efruxifermin showed significant improvements in liver injury markers and fibrosis, with 33% of patients experiencing fibrosis improvement and 25% achieving resolution of NASH, compared to none in the placebo group.

A randomized, double-blind, placebo-controlled phase IIa trial of efruxifermin for patients with compensated NASH cirrhosis. Harrison, SA., Ruane, PJ., Freilich, B., et al.[2023]

Efruxifermin, a long-acting Fc-FGF21 fusion protein, significantly reduced hepatic fat fraction (HFF) in patients with non-alcoholic steatohepatitis (NASH) after 12 weeks of treatment, with reductions of -12.3%, -13.4%, and -14.1% for the 28 mg, 50 mg, and 70 mg doses, respectively, compared to a negligible change of 0.3% in the placebo group.

The treatment was generally well-tolerated, with 89% of patients experiencing at least one treatment-emergent adverse event, mostly mild to moderate gastrointestinal issues, indicating an acceptable safety profile for efruxifermin.

Current treatments for nonalcoholic fatty liver disease (NAFLD) are still not very effective, but weight loss remains a key target for therapy despite being difficult to achieve.

Several investigational drugs show promise for treating NASH, but concerns about long-term safety exist, particularly with vitamin E and other medications like pioglitazone and obeticholic acid, which have notable side effects.

Treatment options for nonalcoholic steatohepatitis - a safety evaluation. Issa, D., Wattacheril, J., Sanyal, AJ.[2017]

In a meta-analysis of 41 randomized controlled trials involving 2,944 participants with non-alcoholic steatohepatitis (NASH), 68% of those on placebo experienced at least one adverse event (AE), highlighting the need for careful safety evaluations in this largely asymptomatic condition.

Serious adverse events were reported in 7.8% of placebo participants, with a notably higher incidence in phase 3 trials and those funded by pharmaceutical companies, indicating that the context of the study may influence safety outcomes.
