SOUTH SAN FRANCISCO, Calif., Nov. 08, 2024 (GLOBE NEWSWIRE) -- Akero Therapeutics, Inc. (Nasdaq: AKRO), a clinical-stage company developing transformational treatments for patients with serious metabolic diseases marked by high unmet medical need, including metabolic dysfunction-associated steatohepatitis (MASH), today reported third quarter financial results for the period ending September 30, 2024 and provided business updates.

"The third quarter of 2024 marked an important milestone for EFX with the first patient dosed in the Phase 3 SYNCHRONY Outcomes study," said Andrew Cheng, president and CEO. "With this advancement, all three of our Phase 3 studies are actively enrolling — furthering our assessment of the safety and efficacy of EFX and moving us closer to delivering a differentiated treatment option, if approved, to patients living with MASH."

Phase 3 SYNCHRONY Program

• Akero's Phase 3 SYNCHRONY program is comprised of three ongoing, randomized, placebo-controlled trials evaluating the safety and tolerability of EFX to support marketing applications for both pre-cirrhotic MASH (F2-F3) and compensated cirrhosis (F4) due to MASH. The SYNCHRONY program builds on two biopsy-based Phase 2b studies in corresponding patient populations, with a combined total of 300 patients treated for up to 96 weeks.
  
• SYNCHRONY Outcomes (F4, compensated)
  
  • SYNCHRONY Outcomes is a two-cohort study evaluating EFX in the treatment of patients with compensated cirrhosis (F4) due to MASH. Patients were first dosed in the study in the third quarter of 2024 and are receiving weekly injections of either EFX 50mg or placebo.
  • The primary histology endpoint, for Cohort 1 only, is the proportion of patients experiencing ≥ 1-stage improvement in fibrosis and no worsening of steatohepatitis after 96 weeks of treatment.
  • The primary outcomes endpoint is measured as the time from randomization to first occurrence of any of the protocol-specified clinical events across all patients enrolled in Cohort 1 and Cohort 2.
• SYNCHRONY Histology (F2-F3)
  • SYNCHRONY Histology is a two-cohort study evaluating EFX in the treatment of patients with pre-cirrhotic MASH, fibrosis stage 2 or 3 (F2-F3). Patients are receiving weekly injections of EFX 28mg, EFX 50mg, or placebo.
  • The primary histology endpoint (Cohort 1 only), to support an application for accelerated approval, is the proportion of patients experiencing ≥ 1-stage fibrosis improvement AND resolution of MASH after 52 weeks of treatment.
  • All patients in Cohort 1 and Cohort 2 will be evaluated for long-term clinical outcomes for up to 240 weeks of treatment.
  • Results for the 52-week primary histology endpoint are expected in the first half of 2027.
    
• SYNCHRONY Real-World (F1-F4)
  
  • SYNCHRONY Real-World is enrolling patients with MASH or metabolic dysfunction-associated steatotic liver disease (MASLD) to receive weekly injections of EFX 50mg or placebo. The primary endpoint of safety and tolerability will be assessed after 52 weeks of treatment.
  • Results from the SYNCHRONY Real-World study are expected in 2026.
    

Phase 2b SYMMETRY Study

• The ongoing Phase 2b SYMMETRY study is evaluating the efficacy and safety of EFX in patients with compensated cirrhosis (F4) due to MASH, who were treated with EFX 28mg, EFX 50mg or placebo for up to 96 weeks.
• All planned end-of-treatment biopsies have been collected. Consistent with the protocol, enrolled patients continue in the study through follow-up assessments 30 days after completion of treatment with EFX or placebo.
• Week 96 results are on track to be reported in February 2025.
  

Third Quarter 2024 Financial Results

• Akero's cash, cash equivalents and short and long-term marketable securities as of September 30, 2024, were $787.1 million.
• Akero believes that its current cash, cash equivalents, and short- and long-term marketable securities will be sufficient to fund its Phase 3 SYNCHRONY Histology and Real-World studies through readout of their respective primary endpoints and Akero's current operating plan into the second half of 2027.
• Research and development expenses for the three-month period ended September 30, 2024 were $72.2 million, compared to $38.6 million for the comparable period in 2023. These increases were attributable to higher expenses associated with the ongoing SYMMETRY study, the ongoing Phase 3 SYNCHRONY Histology and Real-World studies, initiation of the Phase 3 SYNCHRONY Outcomes study, and manufacture of clinical supplies for Phase 3 and potential marketing applications, as well as higher expenses for personnel.
• General and administrative expenses for the three-month period ended September 30, 2024 were $9.5 million, compared to $8.0 million for the comparable period in 2023. These increases are attributable to higher expenses for personnel, professional services and other costs associated with operating as a public company.
• Total operating expenses were $81.7 million for the three-month period ended September 30, 2024, compared to $46.6 million for the comparable period in 2023.
  

About Efruxifermin

Efruxifermin (EFX), Akero's lead product candidate for MASH, is a differentiated Fc-FGF21 fusion protein that has been engineered to mimic the balanced biological activity profile of native FGF21, an endogenous hormone that alleviates cellular stress and regulates metabolism throughout the body. EFX appears to reduce liver fat and inflammation, reverse fibrosis, increase insulin sensitivity and improve lipid metabolism. This holistic approach offers the potential to address the complex, multi-system disease state of MASH, including improvements in lipoprotein risk factors linked to cardiovascular disease — the leading cause of death in MASH patients. EFX is designed to offer convenient once-weekly dosing and has been generally well tolerated in clinical trials to date.

About MASH

MASH is a serious form of MASLD that is estimated to affect more than 17 million Americans. MASH is characterized by an excessive accumulation of fat in the liver that causes stress and injury to liver cells, leading to inflammation and fibrosis, which can progress to cirrhosis, liver failure, cancer and eventually death. MASH is the fastest growing cause of liver transplants and liver cancer in the US and Europe.

About Akero Therapeutics
