MELBOURNE, Australia, May 09, 2022 (GLOBE NEWSWIRE) -- Immuron Limited (ASX: IMC; NASDAQ: IMRN), an Australian biopharmaceutical company focused on developing and commercializing oral immunotherapeutic products for the prevention and treatment of gut pathogens, today is pleased to provide shareholders and the market with a progress update on the planned clinical trial to evaluate the efficacy of Travelan® and two third party non-antibiotic products in Travelers’ Diarrhea

USU’s Infectious Diseases Clinical Research Program (IDCRP), the UK Ministry of Defense and the New York City Travel Clinic are jointly planning to conduct the randomized clinical trial to evaluate the efficacy of three commercially available nutraceutical products for TD and inform strategies for Defense Force Health Protection. The P4TD study is a randomized, double-blind, placebo controlled multicenter clinical trial designed to evaluate the effectiveness of 3 nutraceuticals: A prebiotic (Bimuno®), a probiotic (Florastor®) and IMM-124E (Travelan®) passive immunoprophylaxis verses a placebo, for prophylaxis during deployment or travel to a high-TD risk region ( Identifier: NCT04605783)All study participants (1336 in total) will be randomized to one of the three active products or placebo (334 per arm).

USU have completed the manufacture of the first batches of investigational medicinal products and shipment of these to the first clinical trial sites is now complete. USU are anticipating recruitment of study participants to commence in June 2022 and expect to complete clinical trial enrolment in approximately 18 months.

The clinical protocol has also been amended to extend the treatment period from 13 days to 22 days to cover the COVID-19 quarantine period still required by some countries. The extended time is necessary as those travelers required to quarantine upon arrival who may be still at risk of diarrhea symptoms during this period. The protocol amendment has now been submitted to the ethics board for approval and recruitment will commence once approval has been granted.

The Problem: Travelers’ diarrhea (TD) remains a highly prevalent disease that impacts operational readiness of military personnel and is also debilitating civilian travel. In addition to its acute morbidity, TD is associated with acquisition of antimicrobial resistance genes and long-term sequelae. Current mitigation strategies including pre-travel counseling and antibiotics for prevention and treatment have important limitations, and there are currently no licensed, pathogen-specific vaccines for TD prevention.

The Approach: Prebiotics, probiotics and passive immunotherapy may offer safe and relatively inexpensive preventive strategies by promoting gut resistance to enteropathogens, and potentially lessening the use of antibiotics. USU’s Infectious Diseases Clinical Research Program (IDCRP), the UK Ministry of Defense and the New York City Travel Clinic are jointly conducting a randomized clinical trial to evaluate the efficacy of these nutraceutical products for TD prevention and inform strategies for Force Health Protection.
