SOUTH SAN FRANCISCO, Calif., Aug. 11, 2023 (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, today reported second quarter financial results for the period ending June 30, 2023 and provided business updates.

“We achieved important progress in the clinical development of EFX during the second quarter of this year, including attaining strong and consistent results across our Phase 2 studies to date as reinforced by the Phase 2b SYMMETRY Cohort D study results,” said Andrew Cheng, M.D., Ph.D., president and chief executive officer of Akero. “These results add to the growing body of evidence supporting the ongoing clinical development of EFX and its potential as a transformative NASH therapy. Bolstered by $334.8 million in net proceeds raised in the second quarter, we look forward to initiating our Phase 3 SYNCHRONY Histology and SYNCHRONY Real-World studies later this year to further our goal of developing meaningful therapies for patients living with NASH.”

Phase 3 SYNCHRONY Program

• SYNCHRONY Histology and SYNCHRONY Real-World studies remain on track to begin enrollment by the end of this year.
  • SYNCHRONY Histology will evaluate the efficacy of 28mg and 50mg doses of EFX in patients with biopsy confirmed pre-cirrhotic NASH, fibrosis stage 2 or 3 (F2-F3). The primary endpoint will be ≥ 1-stage fibrosis improvement AND resolution of NASH.
  • SYNCHRONY Real-World will assess safety and tolerability of EFX in patients with non-invasively diagnosed NASH or NAFLD. Key secondary endpoints will include changes in biomarkers of liver fibrosis as well as measures of glycemic control and lipids.
    

Phase 2b SYMMETRY Study Update

• Akero reported topline data from an expansion cohort (N=31) of the Phase 2b SYMMETRY study known as Cohort D.
  • The primary aim of the 12-week study was to assess safety and tolerability of EFX compared to placebo when added to an existing GLP-1 receptor agonist (GLP-1) in patients with Type 2 diabetes and F1-F3 liver fibrosis due to NASH.
  • Results of the Cohort D study showed safety and tolerability endpoints were met. The study also showed that adding EFX to GLP-1 therapy significantly improved non-invasive markers of NASH-related disease, including a 65% relative reduction in liver fat for the EFX-treated group compared with a 10% reduction for the placebo group treated only with GLP-1. In addition, 88% of EFX-treated patients normalized their liver fat to 5% or less, compared with 10% for the placebo group.
• Akero remains on track to report Week 36 results of the Phase 2b SYMMETRY main study in adult patients with cirrhotic NASH (F4, compensated) in the fourth quarter of 2023.

Second Quarter 2023 Financial Results

• The company raised $334.8 million in net proceeds through an At-the-Market facility (ATM) and underwritten registered direct offering, enhancing the company’s cash position in the second half of 2023 as it nears initiation of the Phase 3 SYNCHRONY Histology and SYNCHRONY Real-World studies of Efruxifermin (EFX) in NASH.
• Akero's cash, cash equivalents and short-term and long-term marketable securities for the period ended June 30, 2023 were $658.9 million.
• Akero believes that its current cash, cash equivalents, short-term and long-term marketable securities will be sufficient to fund its current operating plan into 2026.
• Research and development expenses for the three-month period ended June 30, 2023 were $28.0 million, compared to $21.4 million for the comparable period in 2022. Direct EFX program costs increased $5.4 million related to CRO and CMO expenses for our ongoing HARMONY and SYMMETRY studies and personnel and other R&D expenses increased $1.2 million.
• General and administrative expenses for the three-month period ended June 30, 2023 were $7.6 million, compared to $6.2 million for the comparable period in 2022. The increase is attributable to higher expenses for personnel, including non-cash stock-based compensation, and professional services and other costs associated with operating as a public company.
• Total operating expenses were $35.6 million for the three-month period ended June 30, 2023, compared to $27.6 million for the comparable period in 2022.

About NASH
NASH is a serious form of NAFLD (non-alcoholic fatty liver disease) that is estimated to affect 17 million Americans. NASH 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. There are no approved treatments for the condition and NASH is the fastest growing cause of liver transplants and liver cancer in the US and Europe.

About Efruxifermin
Efruxifermin (EFX), formerly known as AKR-001, is Akero’s lead product candidate for NASH, currently being evaluated in the ongoing Phase 2b HARMONY and SYMMETRY studies. EFX is designed to reduce liver fat and inflammation, reverse fibrosis, increase insulin sensitivity and improve lipids. This holistic approach offers the potential to address the complex, multi-system disease state of NASH, including improvements in lipoprotein risk factors linked to cardiovascular disease – the leading cause of death in NASH patients. Engineered to mimic the biological activity profile of native FGF21, EFX is designed to offer convenient once-weekly dosing and has been generally well-tolerated in clinical trials to date.

About Akero Therapeutics
Akero Therapeutics is a clinical-stage company developing transformational treatments for patients with serious metabolic diseases marked by high unmet medical need, including NASH, a disease without any approved therapies. Akero's lead product candidate, EFX, 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 is designed to offer convenient once-weekly subcutaneous dosing. The consistency and magnitude of observed effects position EFX to be a potentially best-in-class medicine, if approved, for treatment of NASH. EFX is currently being evaluated in two Phase 2b clinical trials: the HARMONY study in patients with pre-cirrhotic NASH (F2-F3 fibrosis), and the SYMMETRY study in patients with cirrhotic NASH (F4 fibrosis, compensated). EFX has also been evaluated in an expansion cohort of the SYMMETRY study, Cohort D, comparing the safety and tolerability of EFX to placebo when added to an existing GLP-1 receptor agonist in patients with pre-cirrhotic NASH (F1-F3 fibrosis) and Type 2 diabetes, for which topline results were reported on June 5, 2023. Akero is headquartered in South San Francisco. Visit us at akerotx.com and follow us on LinkedIn and Twitter for more information.
