All AKR-001 Dose Groups Met Week 12 Efficacy Endpoints in NASH Phase 2a BALANCED Study

All AKR-001 dose groups met the primary endpoint, with statistically significant absolute reductions in liver fat of 12-14%

All AKR-001 dose groups met the secondary endpoint of relative reduction in liver fat, with the 50mg and 70mg dose groups achieving >70% relative reductions

Blinded tolerability profile appears consistent with results from previous clinical trials evaluating AKR-001 in patients with Type 2 diabetes

SAN FRANCISCO, CA, USA I March 31, 2020 I Akero Therapeutics, Inc. (Nasdaq: AKRO) today announced that all three AKR-001 dose groups in the BALANCED study met the primary endpoint of absolute change from baseline in liver fat as measured by magnetic resonance imaging – proton density fat fraction (MRI-PDFF) – at week 12. Results for the primary endpoint as well as other week 12 efficacy endpoints are summarized in the table below.

***p<0.001, versus placebo

"The magnitude and rate of improvements in liver fat content and ALT observed over 12 weeks in the BALANCED study are among the most robust NASH clinical trial results reported to date," said Stephen Harrison, M.D., medical director of Pinnacle Clinical Research. "AKR-001 is emerging as one of the most promising drug candidates in development for this serious disease."

The BALANCED study is an ongoing randomized, double-blind, placebo-controlled study in NASH patients. While the study remains blinded, the tolerability profile appears consistent with results from previous clinical trials evaluating AKR-001 in patients with Type 2 diabetes. The adverse events observed most frequently in prior trials were mild/moderate gastrointestinal events and injection site reactions.

After 12 weeks of treatment, patients who have achieved at least a 30% relative reduction in liver fat are eligible for an end-of-study biopsy. Across the AKR-001 dose groups, 75-85% of patients are eligible for biopsies. As of March 30, 2020, 25 end-of-study biopsies have been collected from a total of 50 eligible patients.

We expect to report the top-line safety/tolerability, laboratory measures and paired biopsy data from the BALANCED study in the second quarter of this year. The extent to which the COVID-19 pandemic will interfere with collection of the remaining biopsies and data from other scheduled clinical visits, including the safety follow-up visit at week 20, is unclear. We are delaying the planned initiation of the BALANCED study cohort C in NASH patients who have compensated cirrhosis (F4), Child-Pugh Class A.

"We are encouraged by these results, which support continued development of AKR-001 for treatment of NASH," said Andrew Cheng, M.D., Ph.D., president and CEO of Akero. "AKR-001 has the potential to provide NASH patients with an important treatment option when there are still no approved therapies. We look forward to the full data set with anticipation and are preparing for the next steps in AKR-001's development."

About NASH
NASH (non-alcoholic steatohepatitis) is a serious form of NAFLD (non-alcoholic fatty liver disease) and is estimated to affect 17 million Americans. NASH is closely linked to the obesity and diabetes epidemics seen around the world. 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. NASH is a leading cause of liver transplants in the US and Europe.

About the BALANCED Study
The Phase 2a BALANCED study is a multicenter, randomized, double-blind, placebo-controlled, dose-ranging trial in biopsy-confirmed adult patients with NASH. The main study enrolled a total of 80 patients. Participants were randomized to receive weekly subcutaneous doses of AKR-001 or placebo for up to 16 weeks, with safety and tolerability followed through week 20. The primary efficacy endpoint for the study is absolute change from baseline in hepatic fat fraction measured by magnetic resonance imaging – proton density fat fraction (MRI-PDFF) at week 12. Secondary measures include change from baseline in ALT at 12 weeks, the number of patients who had a decrease of ≥2 points in the NAFLD activity score (NAS) at 24 weeks and safety and tolerability measures.

About AKR-001
AKR-001 is Akero's lead product candidate for NASH, currently being evaluated in the ongoing Phase 2a BALANCED study. AKR-001 is designed to reduce liver fat and inflammation, reverse fibrosis, increase insulin sensitivity and improve lipoproteins. 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, AKR-001 offers convenient once-weekly dosing and has been well-tolerated in clinical trials to date.

About Akero Therapeutics
Akero is a cardio-metabolic NASH company dedicated to reversing the escalating NASH epidemic by developing pioneering medicines designed to restore metabolic balance to improve overall health. The company's lead product candidate, AKR-001, is currently being evaluated in an ongoing Phase 2a clinical trial. Akero Therapeutics is headquartered in San Francisco, CA.
