Deployed US military personnel, essentially representing a long-term traveller population, are particularly affected given their population dynamics and the context in which they seek care and treatment (<a href="https://www.globenewswire.com/Tracker?data=Xv9WFRAhdEQRn7Utr1MwPHm453PnBQ3ORjNEisqoIxrWczM-MWpOaGribJbeo2PfNheJB7-Wbl4D9DOAAxFLV2Q1lBaPKAe3P_s28NUl9gz_3OQ3ljyz1Gk8FYKFyj-lIs5hM5sto50GXwTpXMO2kw9G3kZYONPe2XjwulIQ9hKC94Sbn9PF1IIiDpRudYSWORjS9-bRVr-ONy_1k9IC1ug50Op27Q-hps0Lt860jMs=" rel="nofollow" target="_blank" title="Connor et al., 2012">Connor et al., 2012</a>). Diarrhea is the leading infectious disease threat to the overall health and preparedness of deployed US armed forces, with diarrheagenic E. coli, Campylobacter spp., and Shigella spp. among the most commonly reported etiologies (<a href="https://www.globenewswire.com/Tracker?data=lp0KNxmG_jjPfWbC9_ordwbIc3RZX1NQtEbcoHT9IODfAib1Khlwg-Zre1ylxa7gJlOhckb_ChPfCOwPW8InKxvJvcGjKdTBwfs7P1SDk0eCisvI-NI4iJr5UTlichAi" rel="nofollow" target="_blank" title="Riddle et al., 2006">Riddle et al., 2006</a>). Immuron Platform Technology Immuron’s proprietary technology is based on polyclonal immunoglobulins (IgG) derived from engineered hyper-immune bovine colostrum. Immuron has the capability of producing highly specific immunoglobulins to any enteric pathogen and our products are orally active. Bovine IgG can withstand the acidic environment of the stomach and is resistant to proteolysis by the digestive enzymes found in the Gastrointestinal (GI) tract. Bovine IgG also possesses this unique ability to remain active in the human GI tract delivering its full benefits directly to the bacteria found there. The underlying nature of Immuron’s platform technology enables the development of medicines across a large range of infectious diseases. The platform can be used to block viruses or bacteria at mucosal surfaces such as the Gastrointestinal tract and neutralize the toxins they produce. IMM-124E (Travelan®) IMM-124E was developed using Immuron’s platform technology. IMM-124E is produced from the colostrum of birthing cattle that have been immunised during pregnancy with a vaccine containing the outer antigens of multiple human derived ETEC. A total of 13 ETEC strains are used in the vaccine to produce high levels of antibodies against selected surface antigens from the most common strains of ETEC. (<a href="https://www.globenewswire.com/Tracker?data=-LZMRdd6hIgaFc5n7QzkEsc8qQTAWa8s5dwyI9GeFRvjUf2yguwiLA-JKlq2RdSt8oeBCfIZyl_lI5aj4DTExF8YzWWFdkO0lrRikwXJ0V9v-u6SjJDBk7KNab-HZ07r" rel="nofollow" target="_blank" title="Otto et al., 2011">Otto et al., 2011</a>) The resultant hyperimmune colostrum IMM-124E from ETEC vaccinated cows contains significant levels of polyclonal antibodies specific for ETEC antigens LPS, CFA-I and Flagellin (<a href="https://www.globenewswire.com/Tracker?data=IyriVaUscPRSTFrgTb-xKaRamOB-vUGeRP1-ljqRFUUtaPFih0gqtRJZensPCztBwIyLazG60FLxdhgMeUB-0jY16zmMc-FwXsb3tTPFmPlIuIz633lUwmTMIW55TpluWXmv06z1qXSEiPzX3ODGKA==" rel="nofollow" target="_blank" title="Sears et al., 2017">Sears et al., 2017</a>). The antibodies produced in IMM-124E have been found to have a stronger binding and neutralizing activity (than the antibodies of unvaccinated cattle) against a wide range of LPS antigens including both the variable O-polysaccharide region and the preserved oligosaccharide core ‘R’ region of LPS from the 13 serotypes used in the ETEC vaccine. IMM-124E is manufactured into a tablet form referred to as Travelan®. IMM-529 Immuron is developing IMM-529 as an adjunctive therapy in combination with standard of care antibiotics for the prevention and/or treatment of recurrent Clostridioides difficile infection (CDI). IMM-529 antibodies targeting Clostridioides difficile (C. diff) may help to clear CDI infection and promote a quicker re-establishment of normal gut flora, providing an attractive oral preventative for recurrent CDI. Immuron is collaborating with Dr. Dena Lyras and her team at Monash University, Australia to develop vaccines to produce bovine colostrum-derived antibodies. Dairy cows were immunised to generate hyperimmune bovine colostrum (HBC) that contains antibodies targeting three essential C. diff virulence components. IMM-529 targets Toxin B (TcB), the spores and the surface layer proteins of the vegetative cells. This unique 3-target approach has yielded promising results in pre-clinical infection and relapse models, including (1) Prevention of primary disease (80% P =0.0052); (2) Protection of disease recurrence (67%, P &lt;0.01) and (3) Treatment of primary disease (78.6%, P&lt;0.0001; TcB HBC). Importantly IMM-529 antibodies cross-react with whole cell lysates of many different human strains of C. diff including hypervirulent strains. To our knowledge, IMM-529 is, to date, the only investigational drug that has shown therapeutic potential in all three phases of the disease (<a href="https://www.globenewswire.com/Tracker?data=lxmQjkE72ovF3teHwxZAqPIQNDH1VWBMxEbqBGG8KrwilQakJkt-3k1R96ujeAvKmlVJqVcid8rZAyeOR6Nyxp_DenHGRWvZtW8nzuxb8P_sy0Z1r9xRLJbvSg4nxc-B" rel="nofollow" target="_blank" title="Hutton et al., 2017">Hutton et al., 2017</a>).

Irritable bowel syndrome (IBS) is a common condition where you experience symptoms related to your digestive system. This is sometimes linked to certain foods, lifestyle habits and stress levels or mood. IBS affects around 3 out of every 10 people. Females are more likely than males to be affected. Some key symptoms of IBS include: abdominal pain or discomfort; stomach bloating and wind; chronic diarrhoea or constipation, or alternating between the two.(<a href="https://www.globenewswire.com/Tracker?data=Lz6qIaUOheE8qWw67wXI2ZvURmUrLyg8kpC1BoHkzD3y9R9bmVc0im3Xka8c5tqRmlso3l2mSwkeak6-9otxv3ZfP63GBctEh7eiHlHQkt9sgEAHLaxwUqFJFU9lCJozG1bavRKuzFmqZ0PiUwRnXw==" rel="nofollow" target="_blank" title="healthdirect.gov.au">healthdirect.gov.au</a>) According to available data, the IBS treatment market in Australia is estimated to be a part of the broader "Digestives &amp; Intestinal Remedies" market, generating a revenue of around AU$221.14 million in 2025, with a projected annual growth rate of 3.28%.(<a href="https://www.globenewswire.com/Tracker?data=8yl4ZGuRnCtO_ICCCZ8IVVEsEHV5gYkveyhICPgd6chY0DmQBbVk6ob5JwQ5WFWFjPBgMBOqp8Bx_P7nN2B2TOcJzYkMwWJ94WGSsil33cuRaxT8D3hwbzYrSBk4B_MSkazG230zru4ucr7yZnaXadRJOD3xaoWhF_sdgCQ-quLm0Yp34PJbTuoHVmh7Znh9" rel="nofollow" target="_blank" title="Statista">Statista</a>) References Connor P, Porter CK, Swierczewski B and Riddle MS.
