- Announced Date:
- May 9, 2025
- Indication:
- Non-alcoholic steatohepatitis (NASH)
Announcement
Akero Therapeutics, Inc presented results from the Phase 2b SYMMETRY trial demonstrating the potential of efruxifermin (EFX) to improve fibrosis in compensated cirrhosis (F4) caused by metabolic dysfunction-associated steatohepatitis (MASH), in a late-breaking oral presentation at the European Association for the Study of the Liver (EASL) Congress 2025 taking place May 7-10, in Amsterdam, the Netherlands.
AI Summary
At the EASL Congress 2025 in Amsterdam, Akero Therapeutics shared encouraging results from its Phase 2b SYMMETRY trial. The study focused on efruxifermin (EFX), showing its potential to improve fibrosis in patients with compensated cirrhosis (F4) caused by MASH, a severe form of liver disease. In this trial, patients receiving the 50mg dose of EFX experienced significant improvements in liver fibrosis compared to those on placebo. The 96-week data highlighted that EFX not only reduced fibrosis but also stabilized liver function without worsening MASH. These findings suggest that EFX might become a breakthrough treatment option for patients with advanced liver disease by addressing a critical unmet need. Akero plans to continue evaluating EFX in further Phase 3 studies to better understand its effects across different stages of MASH.

- Indication:
- Non-alcoholic steatohepatitis (NASH)
Announcement
Akero Therapeutics, Inc today released preliminary topline week 96 results from SYMMETRY, a Phase 2b study evaluating the efficacy and safety of its lead product candidate efruxifermin (EFX) in patients with biopsy-confirmed compensated cirrhosis (F4), Child-Pugh Class A, due to metabolic dysfunction-associated steatohepatitis (MASH).
AI Summary
Akero Therapeutics recently shared promising preliminary week 96 results from its Phase 2b SYMMETRY study. The trial is evaluating efruxifermin (EFX) in patients with biopsy-confirmed compensated cirrhosis (F4) due to metabolic dysfunction-associated steatohepatitis (MASH). In patients who had both baseline and week 96 biopsies, 39% of those treated weekly with 50mg EFX experienced at least a one-stage improvement in liver fibrosis without a worsening of MASH, compared to 15% in the placebo group. In the larger group including all patients, 29% of those on 50mg EFX showed improvement compared to roughly 12% for placebo, which highlights the potential benefit of longer treatment duration. These findings suggest that efruxifermin could help reverse cirrhosis caused by MASH with a good safety profile, encouraging further clinical evaluation.

Announcement
Akero Therapeutics, Inc. announced it has completed enrollment of patients in the double-blind portion of the Phase 3 SYNCHRONY Real-World study of EFX in patients with metabolic dysfunction-associated steatohepatits (MASH) or metabolic dysfunction-associated steatotic liver disease (MASLD) (F1-F4).
AI Summary
Akero Therapeutics, Inc. announced that it has completed enrollment of 601 patients in the double-blind portion of its Phase 3 SYNCHRONY Real-World study, which is testing its lead product candidate, EFX. The study focuses on patients with metabolic dysfunction-associated steatohepatitis (MASH) or metabolic dysfunction-associated steatotic liver disease (MASLD) across fibrosis stages F1 to F4. Participants are receiving once-weekly subcutaneous doses of either 50 mg EFX or a placebo. The key goals of this study are to assess the safety and tolerability of EFX over 52 weeks, along with its effects on markers of liver fibrosis and injury, and other metabolic factors such as glycemic control and body weight.
The enrollment, completed just over a year after the study began in November 2023, highlights the urgent need for new treatments in MASH and MASLD. Akero plans to release data from this study in the first half of 2026.

Efruxifermin (HARMONY) - FDA Regulatory Timeline and Events
Efruxifermin (HARMONY) is a drug developed by Akero Therapeutics for the following indication: Non-alcoholic steatohepatitis (NASH).
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- Efruxifermin (HARMONY)
- Announced Date:
- May 10, 2025
- Indication:
- Non-alcoholic steatohepatitis (NASH)
Announcement
Akero Therapeutics, Inc. announced results from new analyses of the 96-week Phase 2b HARMONY trial of efruxifermin (EFX) in patients with pre-cirrhotic (F2-F3 fibrosis) metabolic dysfunction-associated steatohepatitis (MASH) in an oral presentation and a poster presentation at the European Association for the Study of the Liver (EASL) Congress 2025 taking place May 7-10, in Amsterdam, the Netherlands.
AI Summary
Akero Therapeutics, Inc. recently presented new analyses from the 96‐week Phase 2b HARMONY trial at the European Association for the Study of the Liver (EASL) Congress 2025 in Amsterdam. The study evaluated efruxifermin (EFX) in patients with pre-cirrhotic (F2-F3 fibrosis) metabolic dysfunction-associated steatohepatitis (MASH). In both an oral and a poster presentation, the company shared that AI-based digital pathology, using HistoIndex’s qFibrosis®, aligned well with non-invasive tests such as the ELF test score and FibroScan®. More than half of the patients treated with the 50mg EFX dose were identified as responders across all assessments, compared to fewer than 5% in the placebo group. These analyses highlight EFX’s anti-fibrotic activity, revealing that the use of continuous and sensitive digital scoring can better differentiate treatment effects from placebo response and enable earlier detection of fibrosis response in MASH patients.
