Item 7.01. Regulation FD Disclosure.

On March 4, 2024, Akero Therapeutics, Inc. (the “Company”) issued a press release titled “Akero Therapeutics Reports Statistically Significant Histological Improvements at Week 96 in Phase 2b HARMONY Study.” A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The Company from time to time presents and/or distributes to the investment community slide presentations to provide updates and summaries of its business. A copy of its HARMONY Study slide presentation is being furnished herewith as Exhibit 99.2 to this Current Report on Form 8-K.

The information under this Item 7.01, including Exhibit 99.1 and Exhibit 99.2 hereto, is being furnished herewith and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01. Other Events.

On March 4, 2024, the Company released preliminary topline week 96 results from HARMONY, a Phase 2b study evaluating the efficacy and safety of its lead product candidate efruxifermin (“EFX”) in patients with pre-cirrhotic metabolic dysfunction-associated steatohepatitis (“MASH”), fibrosis stage 2 or 3 (“F2-F3”).

The study previously met its primary endpoint of ≥1 stage improvement in fibrosis with no worsening of MASH after 24 weeks of treatment for both the 50mg EFX (41%) and 28mg EFX (39%) dose groups, compared to 20% for the placebo arm. At week 96, the response rates on this endpoint increased to 75% (p<0.001) for 50mg EFX and 46% (p=0.07) for 28mg EFX, compared to 24% for placebo.

The study also met additional histology endpoints at week 96—notably 36% (p<0.01) and 31% (p<0.01) of patients treated with 50mg EFX and 28mg EFX experienced a 2-stage improvement in fibrosis without worsening of MASH—which is more than 10-fold the placebo rate of 3%. Results for all of the histological endpoints are summarized in the table below, based on either the primary analysis (patients with baseline and week 96 biopsies) or intent-to-treat (ITT) analysis (all randomized and dosed patients, with missing data imputed as non-response).

The placebo-adjusted effect size on fibrosis improvement without worsening of MASH (EFX response rate minus placebo response rate) more than doubled between week 24 and week 96 for the 50mg EFX group, with a slight increase observed for the 28mg EFX group. Specifically, the placebo-adjusted effect sizes for fibrosis improvement without worsening of MASH grew from 21% to 52% between week 24 and week 96 for 50mg EFX and from 20% to 22% for 28mg EFX. Highly statistically significant results for 50mg EFX at week 96 are notable because (1) the study was not fully powered at week 96 and (2) the placebo rate increased rather than decreased. An increase in treatment rate for placebo means that the increases in effect size are attributable to higher EFX treatment responses rather than a decline in placebo rate.

Analysis of the evolution of responses between weeks 24 and 96 indicated not only broader fibrosis improvement without worsening of MASH but also sustained response, particularly at 50mg EFX. Among those patients with available week 96 biopsies whose fibrosis improved at week 24, 92% and 83% of the 50mg and 28mg EFX groups remained responders, respectively, compared to 40% for placebo.

Analysis of a subset of patients with baseline F3 fibrosis who had week 96 biopsies showed EFX’s potential to treat patients with more advanced fibrosis, who are generally considered to be at higher risk of progression to cirrhosis. For this advanced F3 patient population, 68% (p<0.001) and 40% (p=0.053) of the 50mg EFX and 28mg EFX groups, respectively, experienced at least a one-stage improvement in fibrosis without worsening of MASH, compared to 14% for placebo.

EFX was reported to be generally well-tolerated. There were no deaths. Fifteen serious adverse events were reported, which were generally balanced across dose groups. Across both EFX groups, the most frequent adverse events (“AEs”) were grade 1 or 2 gastrointestinal events (diarrhea, nausea, and increased appetite), which were transient in nature. A total of three patients treated with EFX were discontinued due to AEs between week 24 and week 96 (two in the 28mg group and one in the 50mg group), compared with none for placebo.

In October of 2023, the Company reported week 36 results for the SYMMETRY study, a Phase 2b trial in patients with compensated cirrhosis (F4) due to MASH, Child-Pugh class A. The SYMMETRY study was designed to include a second biopsy after 96 weeks of treatment, for which the results remain on track to be reported in the first quarter of 2025.

SOUTH SAN FRANCISCO, Calif., Mar. 4, 2024 — Akero Therapeutics, Inc. (Nasdaq: AKRO), a clinical-stage company developing transformational treatments for patients with serious metabolic disease marked by high unmet medical need, today released preliminary topline week 96 results from HARMONY, a Phase 2b study evaluating the efficacy and safety of its lead product candidate efruxifermin (EFX) in patients with pre-cirrhotic metabolic dysfunction-associated steatohepatitis (MASH), fibrosis stage 2 or 3 (F2-F3). The study previously met its primary endpoint of ≥1 stage improvement in fibrosis with no worsening of MASH after 24 weeks of treatment for both the 50mg EFX (41%) and 28mg EFX (39%) dose groups, compared to 20% for the placebo arm. At week 96, the response rates on this endpoint increased to 75% (p<0.001) for 50mg EFX and 46% (p=0.07) for 28mg EFX, compared to 24% for placebo.

The study also met additional histology endpoints at week 96—notably 36% (p<0.01) and 31% (p<0.01) of patients treated with 50mg EFX and 28mg EFX experienced a 2-stage improvement in fibrosis without worsening of MASH—which is more than 10-fold the placebo rate of 3%. Results for all of the histological endpoints are summarized in the table below, based on either the primary analysis (patients with baseline and week 96 biopsies) or intent-to-treat (ITT) analysis (all randomized and dosed patients, with missing data imputed as non-response).

“Notwithstanding inherent limitations in making cross-trial comparisons, the statistically significant results for ≥1-and 2-stage fibrosis improvement and no worsening of MASH observed for 50mg EFX at week 96 are the largest response rates reported publicly to date for these endpoints in any MASH population,” said Stephen Harrison, M.D., medical director of Pinnacle Clinical Research and the HARMONY study’s principal investigator. “I believe the magnitude and general consistency of results observed across the Phase 2a BALANCED and Phase 2b HARMONY studies in patients with pre-cirrhotic MASH are reasons to be optimistic about results of the ongoing Phase 3 SYNCHRONY Histology study and the potential for EFX to be an important MASH medicine, if approved.”

The placebo-adjusted effect size on fibrosis improvement without worsening of MASH (EFX response rate minus placebo response rate) more than doubled between week 24 and week 96 for the 50mg EFX group, with a slight increase observed for the 28mg EFX group. Specifically, the placebo-adjusted effect sizes for fibrosis improvement without worsening of MASH grew from 21% to 52% between week 24 and week 96 for 50mg EFX and from 20% to 22% for 28mg EFX. Highly statistically significant results for 50mg EFX at week 96 are notable because (1) the study was not fully powered at week 96 and (2) the placebo rate increased rather than decreased. An increase in treatment rate for placebo means that the increases in effect size are attributable to higher EFX treatment responses rather than a decline in placebo rate.

Analysis of the evolution of responses between weeks 24 and 96 indicated not only broader fibrosis improvement without worsening of MASH but also sustained response, particularly at 50mg EFX. Among those patients with available week 96 biopsies whose fibrosis improved at week 24, 92% and 83% of the 50mg and 28mg EFX groups remained responders, respectively, compared to 40% for placebo.

Analysis of a subset of patients with baseline F3 fibrosis who had week 96 biopsies showed EFX’s potential to treat patients with more advanced fibrosis, who are generally considered to be at higher risk of progression to cirrhosis. For this advanced F3 patient population, 68% (p<0.001) and 40% (p=0.053) of the 50mg EFX and 28mg EFX groups, respectively, experienced at least a one-stage improvement in fibrosis without worsening of MASH, compared to 14% for placebo.

“We believe the statistically significant 2-stage improvement in fibrosis without worsening of MASH observed in approximately one in three EFX-treated patients sets EFX apart,” said Andrew Cheng, M.D., Ph.D., president and chief executive officer of Akero. “Today’s results show that longer exposure to EFX has the potential to yield sustained fibrosis improvement as well as widening anti-fibrotic treatment responses across the treated patient populations. We look forward to continuing our evaluation of EFX in patients with pre-cirrhotic MASH and cirrhosis due to MASH in our ongoing Phase 3 SYNCHRONY program, in which two out of three studies are actively enrolling.”

About MASH

MASH (metabolic-associated steatohepatitis) is a serious form of MASLD (metabolic-associated steatotic liver disease) 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. There are no approved treatments for the condition and MASH is the fastest growing cause of liver transplants and liver cancer in the United States and Europe.

About the HARMONY Study

The Phase 2b HARMONY study is a multicenter, randomized, double-blind, placebo-controlled, dose-ranging trial in biopsy-confirmed adult MASH patients with fibrosis stage 2 or 3. The study enrolled a total of 128 patients, randomized to receive once-weekly subcutaneous dosing of 28mg or 50mg EFX, or placebo for 24-weeks, 126 of whom received at least one study dose. The primary efficacy endpoint for the study was the proportion of subjects who achieve at least one-stage fibrosis improvement without worsening of MASH at week 24. Week 96 secondary measures included ≥1 stage fibrosis improvement and no worsening of MASH, 2-stage fibrosis improvement without worsening of MASH, at least one-stage fibrosis improvement and MASH resolution, change from baseline in liver enzymes, noninvasive markers of liver fibrosis, glycemic control, lipoproteins, and body weight as well as safety and tolerability measures.

About EFX

Efruxifermin (EFX), is Akero’s lead product candidate for MASH, currently being evaluated in the ongoing Phase 2b SYMMETRY, Phase 3 SYNCHRONY Histology, and Phase 3 SYNCHRONY Real-World studies. EFX has been observed to reduce liver fat and inflammation, reverse fibrosis, increase insulin sensitivity and improve lipoproteins in multiple clinical trials. This holistic profile 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. 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 metabolic dysfunction-associated steatohepatitis (MASH), a disease without any approved therapies. Akero’s lead product candidate, EFX, is currently being evaluated in two ongoing Phase 3 clinical trials: the SYNCHRONY Histology study in patients with pre-cirrhotic MASH (F2-F3 fibrosis) and the SYNCHRONY Real-World study in patients with MASH or MASLD. A third clinical trial, the SYNCHRONY Outcomes study in patients with cirrhosis due to MASH, is expected to be initiated in the first half of 2024. The Phase 3 SYNCHRONY program builds on the results of two Phase 2b clinical trials, the HARMONY study in patients with pre-cirrhotic MASH and the SYMMETRY study in patients with cirrhosis due to MASH. Akero is headquartered in South San Francisco. Visit us at akerotx.com and follow us on LinkedIn and Twitter for more information.
