Akero Remains on Track to Report Phase 2b HARMONY Study Results in the Third Quarter of This Year

SOUTH SAN FRANCISCO, Calif., Feb. 25, 2022 (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 fourth quarter and full year financial results for the period ending December 31, 2021.

"Our confidence in efruxifermin’s (EFX’s) potential to be a best-in-class FGF21 analog for the treatment of NASH continues to grow,” said Andrew Cheng, M.D., Ph.D., president and chief executive officer of Akero. “In 2021 we built on the strong results from our Phase 2a study evaluating EFX in patients with biopsy-confirmed nonalcoholic steatohepatitis (NASH) by initiating two Phase 2b clinical trials in patients with pre-cirrhotic and cirrhotic NASH. We continue to advance our clinical trials and look forward to reporting our first set of Phase 2b results in the third quarter of this year, consistent with prior guidance.”

Phase 2b HARMONY Study Update

• Enrollment for the HARMONY study, a multicenter, randomized, double-blind, placebo-controlled, clinical trial in patients with biopsy-confirmed NASH with fibrosis stage 2 or 3, was completed in February 2022.
• Consistent with initial guidance, Akero remains on track to report HARMONY results in the third quarter of this year.

Manufacturing Update

• Through its drug substance manufacturing partner, Boehringer Ingelheim, Akero recently completed manufacture of EFX drug substance for Phase 3 clinical trials, using the process and scale envisaged for post-approval commercial production.
• Manufacture of a new lyophilized drug product formulation in a pre-filled, dual-chamber syringe device has been established at commercial production scale by Vetter Pharma, Akero’s drug product and device manufacturing partner. This dual-chamber device, which is designed to enable convenient, weekly self-administration by patients, is intended to be the commercial presentation for EFX drug product, if approved. Release of clinical batches to support Phase 3 initiation is expected to be completed in 2022.

Full Year and Fourth Quarter 2021 Financial Results

• Akero's cash, cash equivalents and short-term marketable securities for the year ended December 31, 2021 were $188.3 million.
• Akero believes that its cash, cash equivalents and short-term marketable securities will be sufficient to fund its current operating plan into the third quarter of 2023.
• Research and development expenses for the three-month and twelve-month periods ended December 31, 2021 were $27.7 million and $81.8 million, respectively, compared to $25.7 million and $64.9 million for the comparable periods in 2020. These increases are attributable to higher costs related to Akero's EFX program, including third-party contract manufacturing, contract research organization costs associated with the HARMONY and SYMMETRY studies and internal personnel costs.
• General and administrative expenses for the three-month and twelve-month periods ended December 31, 2021 were $4.7 million and $19.1 million, respectively, compared to $4.1 million and $15.2 million for the comparable periods in 2020. These increases are 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 $32.4 million and $100.9 million for the three-month and twelve-month periods ended December 31, 2021, respectively, compared to $29.8 million and $80.2 million for the comparable periods in 2020.
  

About NASH
Non-alcoholic steatohepatitis (NASH) is a serious, life-threatening disease that has rapidly emerged as a leading cause of liver failure in the world and is the leading indication for liver transplant among women. An estimated 17.3 million Americans had NASH (fibrosis stages 1-4) in 2016, a number that is predicted to increase to 27.0 million by 2030. NASH is a severe form of nonalcoholic fatty liver disease (NAFLD) characterized by hepatocyte injury, liver inflammation, and fibrosis that can progress to scarring (cirrhosis), liver failure, cancer and death. There are currently no approved therapies for the disease.

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 non-alcoholic steatohepatitis (NASH), a disease without any approved therapies. Akero's lead product candidate, efruxifermin (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). Akero is headquartered in South San Francisco. Visit us at www.akerotx.com for more information.

About the HARMONY Study
The Phase 2b HARMONY study is a multicenter, randomized, double-blind, placebo-controlled, clinical trial in biopsy-confirmed NASH patients with fibrosis stage 2 or 3. Patients have been randomized to receive once-weekly subcutaneous dosing of 28 or 50mg EFX or placebo. The primary endpoint for the trial is fibrosis regression after 24 weeks of treatment. To provide additional safety data, patients will continue to receive EFX or placebo for up to 96 weeks of treatment.

About the SYMMETRY Study
The Phase 2b SYMMETRY study is a multicenter, randomized, double-blind, placebo-controlled, clinical trial in patients with biopsy-confirmed cirrhotic NASH, fibrosis stage 4, compensated. Patients are being randomized to receive once-weekly subcutaneous dosing of 28 or 50mg EFX or placebo. The primary endpoint for the trial is fibrosis regression (reversal of cirrhosis) at 36 weeks. To provide additional safety data, patients will continue to receive EFX or placebo for up to 96 weeks of treatment.
