MELBOURNE, Australia, May 08, 2023 (GLOBE NEWSWIRE) -- Immuron Limited (ASX: IMC; NASDAQ: IMRN), an Australian based and globally integrated biopharmaceutical company that has developed two commercially available oral immunotherapeutic products for the treatment of gut mediated diseases, is pleased to announce that the US Naval Medical Research Center (NMRC) has received approval from the US Food and Drug Administration (FDA) to proceed with the clinical evaluation of a new oral therapeutic targeting Campylobacter and Enterotoxigenic Escherichia coli (ETEC) developed in collaboration with Immuron. The FDA has removed a clinical hold on the Investigational New Drug (IND) application allowing the NMRC to proceed with its plans to evaluate the efficacy of the hyperimmune product to prevent infectious diarrhoea caused by Campylobacter and ETEC which is now active.

The safety and protective efficacy of the product will be tested utilising two controlled human infection-model clinical trials, with one trial focusing on the ability of the hyperimmune product to protect volunteers against ETEC infections, and the second trial focusing on moderate to severe campylobacteriosis. A total of 60 volunteers divided into two inpatient cohorts will be enrolled in the randomized, placebo-controlled trials and randomly assigned to either Cohort 1 ETEC or Cohort 2 C. jejuni controlled human infection models (https://www.who.int/publications/i/item/9789240037816).

The first clinical study will be conducted at the Johns Hopkins University (JHU) Center for Immunization Research (CIR) Inpatient Unit, located at the Johns Hopkins Bayview Medical Campus. The study population will include 30 healthy participants (males or non-pregnant, non-nursing females), aged 18-50 years. Commencement is subject to ethics approval from the Institutional Review Board.

Infectious diarrhoea is the most common illness reported by travellers visiting developing countries and among US troops deployed overseas. The morbidity and associated discomfort stemming from diarrhoea decreases daily performance, affects judgment, decreases morale and declines operational readiness. The first line of treatment for infectious diarrhoea is the prescription of antibiotics. Unfortunately, in the last decade, several enteric pathogens have had an increasing resistance to commonly prescribed antibiotics. In addition, traveller’s diarrhoea is now recognised by the medical community to result in post-infectious sequelae, including post-infectious Irritable Bowel Syndrome and several post-infectious autoimmune diseases. A preventative treatment that protects against enteric diseases is a high priority objective for the US Military.

About Traveller’s Diarrhoea

Traveller’s Diarrhoea is a gastrointestinal infection with symptoms that include loose, watery (and occasionally bloody) stools, abdominal cramping, bloating, and fever, Enteropathogenic bacteria are responsible for most cases, with enterotoxigenic Escherichia coli (ETEC) playing a dominant causative role. Campylobacter spp. are also responsible for a significant proportion of cases. The more serious infections with Salmonella spp. the bacillary dysentery organisms belonging to Shigella spp. and Vibrio spp. (the causative agent of cholera) are often confused with Traveller’s Diarrhoea as they may be contracted while travelling and initial symptoms are often indistinguishable.
