With recent clinical trials still unveiling efimosfermin alfa’s potential, it stands to treat MASH. This chronic condition affects 2% to 5% of US adults, according to the American College of Gastroenterology. This treatment is a mimic of the endogenous fibroblast growth factor 21 (FGF21) protein. Most importantly, it swiftly demonstrates MSH resolution and retaliation fibrosis resolution in patients.
In this context, a phase 2 trial, including 84 participants with biopsy-confirmed F2/F3 MASH, found encouraging results. Patients received once-monthly injections of 300 mg efimosfermin alfa or placebo for 24 weeks. Upon completion of the study, 68% of patients in the treatment group reached MASH resolution with no increase in fibrosis, either. In comparison, only 29% of patients in the placebo group had the same result (P = .002). The available data indicates that efimosfermin has the potential to be a first-in-class treatment for those who experience this debilitating condition.
Understanding MASH and Its Impact
MASH is becoming accepted more widely as a significant health problem, especially for people who are economically disadvantaged and obese. As many as 20% of the adults in this demographic likely have challenges with MASH. If they fail to get treatment, it can result in severe consequences. This has made the search for effective treatments even timelier, as the prevalence of MASH continues to increase.
It regulates several different processes in the body’s metabolism to lower the amount of fat stored in the liver. The trial outcome was an encouraging one. This underscores its unique position as a feasible therapeutic option for patients suffering from this challenging disease.
Trial Findings and Implications
The results from this small efimosfermin alfa trial are remarkable. They reflect a major step forward in expanding treatment options for MASH. This is perhaps best illustrated by the trial’s high rate of MASH resolution. It demonstrated that 45% of subjects in the treatment group had an improvement in fibrosis by at least one stage with no worsening of MASH, compared to only 21% of the placebo group (P = .038).
Dr. Koziel, a researcher involved in the study, emphasized the significance of the findings:
“We saw statistically significant changes in fibrosis improvement.” – Dr. Koziel
The trial’s results illustrate the remarkable potential of efimosfermin. They are an important, symbolic milestone in our battle against fibrosis and fatty liver disease.
The Road Ahead for Treatment
Though efimosfermin alfa is the most advanced of its kind, it is the sole treatment in development for patients. This week, the Food and Drug Administration (FDA) made a groundbreaking move. They recently approved resmetirom (Rezdiffra) for patients impacted by liver scarring due to fatty liver disease. Resmetirom reduces liver fat by stimulating thyroid hormone receptor beta, indicating a growing interest in developing effective therapies for liver conditions.
Science is moving fast. More treatments, like efruxifermin—an FGF21 analogue currently in phase 3 trials—may soon give patients battling MASH and other hepatic disorders more choices and hope.
