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
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
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.
