Highlights:

● Immuron Board approves IMM-529 cGMP manufacturing and to proceed with FDA pre-IND submission

● Recruitment and screening update for Travelan® Controlled Human Infection Model (CHIM) Clinical Trial

Melbourne, Australia, June 22, 2023

Dear Immuron Limited Shareholders (ASX: IMC; NASDAQ: IMRN),

Immuron is pleased to announce that it has approved proceeding with IMM-529 cGMP manufacturing and to proceed with FDA pre-IND submission.

IMM-529 was developed for treatment of Clostridioides difficile (C. difficile) which is an anaerobic, spore-forming, gram-positive bacillus typically associated with gastrointestinal disease. Transmission of C. difficile occurs by ingestion of spores either through person-to-person contact, animal-to-person contact or environment-to-person contact. C. difficile infection (CDI) can cause life-threatening diarrhoea and is the leading healthcare-related gastrointestinal infection in the world.¹

Lumanity, a leading lifescience consulting company conducted an opportunity assessment of IMM-529. Infectious disease experts reacted favourably to the IMM-529 mechanism of action, and its unique ability to target three elements of the CDI infection – the spores, vegetative cells, and Toxin B. Base case yearly revenue in USA for IMM- 529 was estimated at US$92M for the target patient population (limited to second recurrence and later). Positioning IMM-529 earlier than second recurrence could lead to higher uptake. The global CDI market was estimated to increase to $1.7B by 2026, according to a report by GlobalData.²

Pharmaron have scheduled 96 telehealth screening interviews since recruitment for the planned Travelan clinical study was initiated at the end of May 2023 (ASX announcement 30 May 2023). To date 81 potential candidates have been selected for in-person screening visits which are anticipated to commence on the 28 June 2023 at Pharmaron’s Clinical Research Facility Inpatient Unit located in Baltimore, Maryland US. The Phase II clinical trial is designed to evaluate the safety and protective efficacy of Travelan® compared to a placebo in a controlled human infection model (CHIM) in up to 60 healthy participants (males or non-pregnant, non-nursing females), aged 18-50 years.

Thank you for your support.

About Travelers’ diarrhea

Travelers’ diarrhea 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 travelers’ diarrhea as they may be contracted while travelling and initial symptoms are often indistinguishable.
