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 .

It is rich in immunoglobulins, lactoferrin, lysozyme, lactoperoxidase, growth factors and bioactive peptides. Colostrum has higher levels of protein, fat, vitamins, and minerals when compared to milk. This enables full development of the newborn calf in addition to immunity against several pathogens. * Immuron’s proprietary technology platform combines the natural human nutrition & health benefits of bovine colostrum with a novel class of specifically targeted oral polyclonal antibodies that offer delivery within the gastrointestinal (“GI”) tract and can be used to target viruses or bacteria and neutralize the toxins they produce at mucosal surfaces.

Clostridioides Difficile IMMURON’S CLINICAL PROGRAMS – OPPORTUNITY ASSESSMENT › Immuron’s development of IMM - 124E (hyperimmune bovine colostrum) as a prescription medication has the potential to address this unmet need › Primary care physicians (PCP)s impressed with clinical efficacy endpoint targets demonstrating > 80% protection against the development of diarrhea. › If base case efficacy targets are reached, IMM - 124E would mostly be used by travelers going to the highest risk areas (e.g., rural Central America/Asia/Africa). › Based on the estimated market size and pricing, the base case yearly revenue in USA for IMM - 124E is projected at US$102M . › Reaching higher efficacy goals could broaden use. L u C m o a r n p i o t y r a * t e Opp or t u n ity Assessment for IMM - 124E › Infectious disease experts reacted favorably to the IMM - 529 MOA, and its unique ability to target three elements of the rCDI infection – the spores, vegetative cells, and Toxin B › Non - microbiome approaches (such as IMM - 529) are still appealing to experts, who noted that clinical trial efficacy (reduction in relapse rate) and cost/access will be the key drivers of clinical use in recurrent patients, not mechanism of action › Based on the estimated market size, anticipated payer restrictions, pricing, and competition, base case yearly revenue in USA for IMM - 529 is conservatively projected at US$93M for the target patient population (limited to 2nd recurrence and later based on trial design and payer coverage) › Positioning IMM - 529 earlier than second recurrence and/or efficacy targets could lead to higher uptake.
