CAMBRIDGE, Mass.--(BUSINESS WIRE)--
(Nasdaq: AXLA), a clinical-stage biotechnology company focused on leveraging endogenous metabolic modulators (EMMs) to pioneer a new approach for treating complex diseases and improving health, today announced positive top-line data from AXA1125-003.
AXA1125-003 is a placebo-controlled, randomized, multi-arm clinical study assessing the impact of AXA1125 and AXA1957 on safety, tolerability and effects on structures and functions of the liver, as measured by a comprehensive panel of imaging and soluble biomarkers related to metabolism, inflammation and fibrosis. Both of these distinct product candidates are proprietary compositions of amino acids and derivatives that have been designed to support liver health. In this non-IND study, 102 adult non-alcoholic fatty liver disease (NAFLD) subjects with presumed nonalcoholic steatohepatitis (NASH), based on inclusion criteria, were enrolled and dosed in a 2:2:2:1 ratio to receive AXA1125, one of two AXA1957 doses, or placebo administered twice daily for 16 weeks. Study subjects were stratified based on the presence or absence of type 2 diabetes.
Results from the study showed that AXA1125 and AXA1957 were generally well-tolerated, with sustained reductions noted for both product candidates versus placebo in key biomarkers of metabolism, inflammation and fibrosis over 16 weeks. Overall, as compared to placebo, AXA1125 demonstrated larger and more consistent reductions in clinically relevant biomarkers than AXA1957. Among subjects receiving AXA1125, 39% achieved a ≥30% relative reduction in liver fat content (MRI-PDFF), 39% achieved a ≥17 U/L reduction in alanine aminotransaminase (ALT), and 35% achieved a ≥80 mSec reduction in corrected T1 (cT1). Among the 11 subjects with type 2 diabetes receiving AXA1125, a greater proportion achieved each of these thresholds. Emerging evidence suggests that these thresholds of activity increase the likelihood of histopathological improvement in NASH subjects. Notably, the above results were seen without impacting mean body weight or serum lipids.
Manu Chakravarthy, M.D., Ph.D., Chief Medical Officer of Axcella, said, “In AXA1125-003, we were seeking to evaluate safety and tolerability while also determining what differential responses may be seen from AXA1125 and AXA1957 across markers of metabolism, inflammation and fibrosis. It is gratifying that multifactorial activity and a favorable tolerability profile were noted for AXA1125 in this multi-arm, placebo-controlled randomized study, which replicates findings from our previous clinical study in subjects with NAFLD and type 2 diabetes. We believe that these data, coupled with AXA1125’s oral route of administration and favorable tolerability profile to date, reinforce its potential to meaningfully improve the lives of patients with NASH.”
“These data indicate that AXA1125 holds the potential to be a first-line therapy in NASH, with impressive, concordant metabolism, inflammation and fibrosis activity as well as a favorable tolerability profile with no meaningful changes to serum lipids and body weight,” said Stephen A. Harrison, M.D., Medical Director of Pinnacle Clinical Research in San Antonio, TX, visiting professor of Hepatology at the University of Oxford, UK and the principal investigator of AXA1125-003. “Additionally, in the majority of subjects with type 2 diabetes receiving AXA1125, clinically relevant thresholds of activity were observed in non-invasive tests that suggest a higher probability of positive outcomes histopathologically. This is a potential differentiator and is particularly encouraging given that nearly 40% of the NASH population is diabetic and the disease is known to be more severe in these patients.”

AXA1125 and AXA1957 were both generally well tolerated in the study. The adverse events (AEs) experienced in ≥10% of subjects were gastrointestinal (diarrhea, nausea, reduced appetite) and upper respiratory infection. Gastrointestinal AEs were generally mild and transient, self-resolving in two to three weeks on average. Two serious adverse events were reported, both of which were determined to be unrelated to study product administration.
“The findings from this clinical study further validate the strength of our EMM platform and its ability to identify product candidates with the potential to address complex diseases in a multi-targeted manner,” said Bill Hinshaw, President and Chief Executive Officer of Axcella. “Given the strength and consistency of data on AXA1125, we have selected it as our product candidate for NASH and have decided that we will not reinitiate our AXA1957-002 pediatric study, which had recently been suspended due to COVID-19. In the months ahead, we plan to engage with the U.S. Food and Drug Administration (FDA) to discuss our investigational new drug (IND) application for AXA1125, proposed Phase 2b clinical trial in adults and pediatric development program. We give our thanks to the many subjects and investigators who participated in AXA1125-003 and will continue working diligently toward our goal of providing them with an effective and safe treatment option.”

About Endogenous Metabolic Modulators (EMMs)
EMMs are a broad family of molecules, including amino acids, that regulate human metabolism. Axcella is developing a range of novel product candidates that are comprised of multiple EMMs engineered in distinct combinations and ratios to simultaneously impact multiple metabolic pathways to modify the root causes of various complex diseases and improve health.
About Axcella’s Clinical Studies
Each of the company’s clinical studies to date, including AXA1125-003, are or have been conducted as non-investigational new drug application (IND) clinical studies under U.S. Food and Drug Administration regulations and guidance supporting research with food. These studies evaluate product candidates for safety, tolerability and effects on the normal structures and functions in humans, including in individuals with disease. They are not designed or intended to evaluate a product candidate’s ability to diagnose, cure, mitigate, treat or prevent a disease. If Axcella decides to further develop a product candidate as a potential therapeutic, as is the case with AXA1665 and AXA1125, any subsequent clinical studies will be conducted under an IND.
