• Phase 3 SYNCHRONY studies actively screening and on track to begin enrolling by the end of 2023 

SOUTH SAN FRANCISCO, Calif., Nov. 13, 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 third quarter financial results for the period ending September 30, 2023 and provided business updates.

“We continue to be encouraged by the totality of evidence supporting clinical development of EFX for both pre-cirrhotic and cirrhotic NASH,” said Andrew Cheng, M.D., Ph.D., president and chief executive officer of Akero. “We look forward to enrolling the first patients in our Phase 3 SYNCHRONY Histology and SYNCHRONY Real-World studies later this year.”

Phase 3 SYNCHRONY Program

• The SYNCHRONY Histology and SYNCHRONY Real-World studies began screening in September 2023 and remain on track to begin enrollment by the end of this year.
  • SYNCHRONY Histology will evaluate the efficacy of 28mg and 50mg doses of efruxifermin (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.
  • A Type B, End-of-Phase-2 meeting request to review the design of the planned SYNCHRONY Outcomes study in light of the Week 36 Phase 2b SYMMETRY data was submitted to FDA in October. As currently planned, SYNCHRONY Outcomes will evaluate EFX in the treatment of patients with compensated cirrhosis (F4) due to NASH.

Phase 2b SYMMETRY Study Week 36 Analysis

• In October 2023, Akero reported Week 36 results from SYMMETRY, a 96-week Phase 2b study evaluating the efficacy and safety of its lead product candidate EFX in patients with compensated cirrhosis (F4) due to NASH.
• Although the primary endpoint of at least a one-stage improvement in liver fibrosis with no worsening of NASH at week 36 was not met, statistically significant results for NASH resolution, as well as non-invasive markers of liver injury and fibrosis, insulin sensitization and lipoproteins were observed, including:
  • 22% (28mg EFX) and 24% (50mg EFX) of patients experienced at least a one-stage improvement in liver fibrosis with no worsening of NASH, compared to 14% for placebo (not statistically significant);
  • 4% of patients in each EFX dose group experienced a three- or two-stage reversal of fibrosis with no worsening of NASH, compared to 0% for placebo; and
  • 63% (28mg EFX) and 60% (50mg EFX) of patients experienced statistically significant resolution of NASH, compared to 26% for placebo—the first known public report of a clinical trial showing statistically significant NASH resolution, in patients with cirrhosis irrespective of development stage, treatment duration or mechanism of action.
• Across EFX groups, the most frequent adverse events were gastrointestinal, and mainly of mild to moderate severity.

Phase 2b HARMONY Study Week 96 Analysis

• Week 96 results from HARMONY, a 96-week Phase 2b HARMONY study evaluating the efficacy and safety of EFX in biopsy-confirmed patients with F2-F3 NASH, remain on track to be reported in the first quarter of 2024.        

Third Quarter 2023 Financial Results

• Akero's cash, cash equivalents and short-term and long-term marketable securities for the period ended September 30, 2023 were $613.0 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 September 30, 2023 were $38.6 million, compared to $25.1 million for the comparable period in 2022. Direct EFX program costs increased $14.1 million related to CRO and CMO expenses for our ongoing HARMONY and SYMMETRY studies as well as the initiation of the Phase 3 SYNCHRONY program and personnel and other R&D expenses decreased $0.5 million.
• General and administrative expenses for the three-month period ended September 30, 2023 were $8.0 million, compared to $11.0 million for the comparable period in 2022. The decrease is attributable primarily to lower non-cash stock-based compensation expense, offset by an increase in expenses for personnel and professional services.
• Total operating expenses were $46.6 million for the three-month period ended September 30, 2023, compared to $36.1 million for the comparable period in 2022.

About NASH

NASH is a serious form of non-alcoholic fatty liver disease (NAFLD) 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. Approximately 20% of patients with NASH will progress to cirrhosis, which has a higher risk of mortality. 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 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. 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). Akero is headquartered in South San Francisco. Visit us at akerotx.com and follow us on LinkedIn and Twitter for more information.
