Axcella Presents Data at The Liver Meeting™ Providing New Mechanistic Insights on Observed Multifactorial Effects of its Liver Product Candidates

  • AXA1665 enhances amino acid metabolism and improves ammonia disposal in subjects with mild and moderate hepatic insufficiency
  • AXA1125 impacts key biochemical pathways and molecular mediators regulating amino acid catabolism, insulin sensitivity, inflammation and fibrogenesis
  • Data reinforce product candidates’ potential to address unmet needs in hepatic encephalopathy (HE) and nonalcoholic steatohepatitis (NASH)

CAMBRIDGE, Mass.–(BUSINESS WIRE)–Axcella Health (Nasdaq: AXLA), a biotechnology company pioneering the research and development of novel interventions to address dysregulated metabolism and support health, today announced that it will present new data on the company’s liver product candidates at The Liver MeetingTM, the Annual Meeting of the American Association for the Study of Liver Diseases (AASLD), being held this week in Boston. Two poster presentations highlight mechanistic data from preclinical and non-IND clinical studies of two of its investigational candidates, AXA1665 and AXA1125.

“Simultaneous dysregulation in multiple pathways is a fundamental feature of complex diseases such as hepatic encephalopathy (HE) and nonalcoholic steatohepatitis (NASH),” explains Dr. Manu Chakravarthy, M.D., Ph.D., Axcella’s SVP of Clinical Development and Chief Medical Officer. “In order to effectively address these conditions, a safe, multifactorial approach is required. We are excited to share our latest clinical findings, which both affirm and deepen our mechanistic understanding of the ways in which AXA1665 and AXA1125 may impact key biochemical and molecular pathways.”

Poster #0432 showcases the distinctive pharmacokinetic profile of AXA1665, as compared to a standard protein supplement, with improved nitrogen and ammonia handling by AXA1665 in subjects with hepatic insufficiency.

  • AXA1665 enhanced anabolism-associated amino acids (AAs) and the clearance of ammoniagenic aromatic AAs (e.g., phenylalanine and tyrosine, which are inversely related to health consequences in patients with cirrhosis).
  • AXA1665 administration, relative to the control group, demonstrated a decrease in fasted plasma ammonia concentration, with increased blood urea nitrogen (within the normal range) suggestive of enhanced ureagenesis.

Poster #2134 further delineates mechanisms underlying the previously reported observations of AXA1125 from a non-IND clinical study.

  • No increases were observed in basal plasma branched chain amino acid (BCAA) levels despite the AXA1125 composition containing 24g of BCAAs per day. These findings are at least partially due to increased BCAA catabolism, as shown by the induction of the BCAA metabolite, C5-OH/C3-DC, induced by AXA1125.
  • Propensity to improve insulin sensitivity was supported by enhanced insulin-dependent glucose uptake in primary human hepatocytes treated with the components of AXA1125.
  • Coordinated effects of AXA1125 to dampen the inflammatory and fibrogenic responses were manifested by decreased proinflammatory (Trp, Kyn, YKL-40) and fibrogenic (Pro, His) markers.

About Endogenous Metabolic Modulators

Endogenous metabolic modulators (EMMs) are a broad family of molecules, including amino acids, which fundamentally impact and regulate human metabolism. Our AXA Candidates are comprised of EMMs that individually have a history of safe use as food. We believe that, unlike conventional targeted interventions currently used to address dysregulated metabolism, EMM compositions have the potential to directly and simultaneously modulate multiple metabolic pathways implicated both in complex diseases and overall health.

About Non-IND Clinical Studies

Axcella conducts Institutional Review Board (IRB)-approved, non-investigational new drug application (Non-IND) clinical studies in humans with its AXA Candidates under U.S. Food and Drug Administration regulations and guidance supporting research with food. In these studies, Axcella evaluates in humans, including in individuals with disease, AXA Candidates for safety, tolerability and effects on the normal structures and functions of the body. Non-IND, IRB-Approved Clinical Studies are not designed or intended to evaluate an AXA Candidate’s ability to diagnose, cure, mitigate, treat or prevent a disease. If Axcella decides to further develop an AXA Candidate as a potential therapeutic, subsequent studies will be conducted under an IND.

Internet Posting of Information

Axcella uses its website, www.axcellahealth.com, as a means of disclosing material nonpublic information and for complying with its disclosure obligations under Regulation FD. Such disclosures will be included on the company’s website in the “Investors and News” section. Accordingly, investors should monitor such portions of the company’s website, in addition to following its press releases, SEC filings and public conference calls and webcasts.

About Axcella Health

Axcella is designing and developing AXA Candidates, compositions of endogenous metabolic modulators, or EMMs, engineered in distinct ratios, designed to target and maximize the fundamental role that EMMs play in regulating multiple metabolic functions. Axcella’s AXA Candidates are generated from its proprietary, human-focused AXA Development Platform. Axcella believes its expertise and capabilities in EMMs position it to become a preeminent biotechnology company reprogramming metabolism to address a diverse set of complex diseases and support health. Axcella’s AXA Development Platform has already produced a pipeline of product candidates in programs targeting liver, muscle and blood. Axcella was founded by Flagship Pioneering.
