Immuron Aims to Secure FDA Approval for IMM-124E to Prevent Travelers’ Diarrhea


Key Points

  • Immuron to develop U.S. registration dossier for IMM-124E for Travelers’ Diarrhea
  • Company anticipates significant inflection in sales with successful FDA registration of IMM-124E
  • Company to pursue rapid path for clinical development of IMM-124E
  • Travelan® safely and effectively marketed for well over 10 years in Australia and currently sold in U.S. and Canada as dietary supplement and natural health product, respectively, with limited marketing

MELBOURNE, Australia, April 11, 2019 (GLOBE NEWSWIRE) -- Immuron Limited (ASX: IMC; NASDAQ: IMRN), an Australian biopharmaceutical company focused on developing and commercializing oral immunoglobulin therapeutics for the treatment of gut mediated diseases, today announced plans to pursue clinical development of IMM-124E, its bovine polyclonal antibody drug candidate, through a formal FDA registration pathway as a drug to prevent travelers’ diarrhea (TD).  

The Company currently markets and sells Travelan® as a Therapeutic Goods Administration (TGA) listed medicine for prevention of travelers’ diarrhea in Australia, and also markets Travelan® in the U.S. and Canada as a dietary supplement, and natural health product, respectively, for digestive tract protection. Travellers diarrhea affects between 30 and 60% of over one billion international travellers every year and symptoms of nausea, vomiting, fever, stomach cramps and diarrhea, can last up to 7 days. Travelan® has been shown in clinical studies to be an effective preventative against TD when taken as instructed.

“This is an important strategic initiative towards enhancing commercialization of the Travelan®/IMM-124E franchise,” said Dr. Gary S. Jacob, CEO of Immuron Limited.  “It is important to note that Travelan® and IMM-124E, our drug candidate presently in clinical development in gut mediated diseases, are one and the same.  We believe seeking FDA registration for IMM-124E as a drug to prevent travelers’ diarrhea offers the potential for substantial sales benefits to Immuron. We are moving aggressively forward to develop IMM-124E through the FDA by planning to file an Investigational New Drug (IND) application for prevention of travelers’ diarrhea, and pursuing with FDA a rapid path for its clinical development.”

Immuron forecasts IMM-124E’s potential peak annual sales at over USD $100 million annually as an FDA approved drug to prevent TD.

IMM-124E recently completed a non-alcoholic steatohepatitis (NASH) trial and is currently being evaluated in ongoing clinical trials in alcoholic steatohepatitis (ASH) and pediatric non-alcoholic fatty liver disease (NAFLD).  The Company expects top-line data from the clinical trial of IMM-124E in ASH patients to be released by late 2Q 2019. Immuron is focused on establishing whether statistically-significant reductions in systemic lipopolysaccharide (LPS) endotoxin, observed in the completed Phase 2 trial in NASH patients, are observed in the ASH trial where lowering systemic LPS is the primary endpoint for the trial. Together with the completed trial in NASH patients, the Company will be looking to determine IMM-124E’s potential in treating conditions where systemic LPS is believed to play a critical role.

About IMM-124E

IMM-124E is a first-in class, oral polyclonal antibody therapy developed to target the endotoxin lipopolysaccharide (LPS) and other pathogenic bacterial components in the human gastrointestinal tract reducing LPS-related inflammation and systemic translocation. In a recent study completed in 133 biopsy-proven NASH patients where patients were treated with either IMM-124E or placebo for 6 months, treatment with IMM-hjjj124E resulted in a statistically significant reduction of serum LPS levels when compared to placebo. In addition, biomarkers associated with inflammation were also reduced by IMM-124E including ALT, AST and cytokeratin-18. In addition to the adult NASH study, IMM-124E is also being evaluated in two NIH funded Phase II proof-of-concept studies of IMM-124E in children with pediatric NAFLD and adults with  alcoholic steatohepatitis.
