Immuron completes in-patient phase of IMM-124E Phase 2 clinical trial

The inpatient challenge phase of the Travelan^® clinical study led by Principal Investigator Dr Mohamed Al- Ibrahim at the Pharmaron CPC FDA inspected Clinical Research Facility Inpatient Unit located in Baltimore, Maryland US, has been completed. The double-blind study was separated into two cohorts of approx. 30 subjects (60 in total) dosed with Travelan or placebo for two days prior to challenge continuing for a total of 7 days. All study participants were challenged with Escherichia coli, monitored for symptoms, and treated with antibiotics. Safety data at two weeks and 4 weeks post challenge has been collected and the final 6 month follow up interviews will be initiated in January 2024 and are expected to be completed in April 2024. Headline results from the clinical trial are anticipated to be reported in June 2024. The Phase 2 clinical trial is designed to evaluate the safety and protective efficacy of Travelan^® compared to a placebo in a controlled human infection model (CHIM). The primary efficacy outcome is prevention and/or reduction of moderate to severe diarrhea. ClinicalTrials.gov Identifier: NCT05933525.

Immuron completes in-patient phase of CampETEC Phase 2 clinical trial

The NMRC has recently completed the in-patient stage of the campylobacter challenge clinical study. The clinical study is being led by Principal Investigator Dr Kawsar Talaat, MD at the Johns Hopkins University (JHU) Center for Immunization Research (CIR) Inpatient Unit, located at the JHU Bayview Medical Campus, Baltimore, Maryland. U.S. A total of 30 participants were enrolled in the study, of which 27 participants were dosed with either the Investigational Medical Product or placebo and all subjects were challenged with Campylobacter. All study volunteers have now been treated with antibiotics and discharged from the clinic. The study participants will return as outpatients for several follow-up visits, with the last patient last visit scheduled to be completed in June 2024. Headline results from the clinical trial are anticipated to be reported in H2 2024. The Phase 2 clinical trial is designed to evaluate the safety and protective efficacy of the new product manufactured by Immuron compared to a placebo in a controlled human infection model (CHIM). The primary efficacy outcome is prevention and/or reduction of moderate to severe diarrhea. ClinicalTrials.gov Identifier: NCT06122870.

Immuron Limited

Uniformed Services University Travelan^® clinical field trial reaches 50% recruitment

USU’s Infectious Diseases Clinical Research Program (IDCRP), the UK Ministry of Defence and the New York City Travel Clinic are jointly conducting the randomized clinical trial to evaluate the efficacy of Travelan^® in Travelers’ Diarrhea. The P2TD study is a randomized, double-blind, placebo controlled multicenter clinical trial designed to evaluate the effectiveness of IMM-124E (Travelan^®) passive immunoprophylaxis verses a placebo, during deployment or travel to a high-TD risk region (ClinicalTrials.gov Identifier: NCT04605783). All study participants (868 in total) will be randomized to Travelan^® or placebo (434 per arm).

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: 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 Defence 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.

Completion of IMM-529 drug substance manufacture by CSIRO

Immuron ’s manufacturing campaign for a new therapeutic product which targets the Clostridioides Difficile (C. Diff) bacteria, IMM-529 drug substance was completed in December 2023 by CSIRO Agriculture and Food. IMM-529 is the second therapeutic drug candidate the company is planning to take into the clinic and has been specifically developed to target (i) toxin B, (ii) spores and (iii) vegetative cells of Clostridioides Difficile (C. Diff) which are thought to be the primary cause of C. Diff disease recurrences. A research services agreement has recently been executed with Monash University to assist with vaccine manufacture and stability testing of the Investigational Medical Product to support the pre-IND information package. A research services agreement has also been executed with VivoPharm Global Preclinical Services to conduct a GLP compliant toxicity study in rodents. The study protocol has been submitted and approved by the Animal Ethics Committee and the study is planned to commence in Q1 2024. The company is working towards submitting a Pre-IND information package to the U.S. Food and Drug Administration (FDA) in H1 2024.

Invitation to present at The Military Health System Research Symposium (MHSRS)

The MHSRS is the U.S. Department of Defense’s premier scientific meeting that focuses specifically on the unique medical needs of the Warfighter. This annual symposium brings together 3,000 healthcare professionals, researchers, U.S DoD leaders and decision markers as well as various funding bodies. The company attended the meeting as an Exhibitor and presented two posters at the event. One entitled ‘Clinical Evaluation of an Oral prophylactic for prevention of Travelers diarrhea in active-duty military assigned abroad.’ The company was also invited by the Medical Technology Enterprise Consortium (MTEC) to showcase Immuron and its collaborative work with the U.S. Department of Defense including an overview of the current MTEC award entitled ‘Biologics license application of a bovine immunoglobulin supplement that prevents travelers’ diarrhea caused by enterotoxigenic Escherichia coli (ETEC).’ The Naval Medical Research Command (NMRC) also presented a poster at the symposium on the new oral therapeutic targeting Campylobacter and Enterotoxigenic Escherichia coli (ETEC) developed in collaboration with Immuron. The NMRC poster is entitled ‘Research and Development of Hyperimmune Bovine Colostrum Products for the Prevention of Travelers’ Diarrhea.’ Copies of the presentations are available on the Company’s website. https://www.immuron.com.au/product-science/

Directors’ report

31 December 2023

(continued)

Your directors present their report on the consolidated entity consisting of Immuron Limited and the entities it controlled at the end of, or during, the half-year ended 31 December 2023.

Directors

The following persons were directors of Immuron Limited during the whole of the half-year and up to the date of this report:

Mr Paul Brennan, Independent Non-Executive Chairman

Dr Roger Aston, Independent Non-Executive Director

Mr Daniel Pollock, Independent Non-Executive Director

Mr Stephen Anastasiou, Independent Non-Executive Director

Prof. Ravi Savarirayan, Independent Non-Executive Director

Principal activities

We are a commercial and clinical-stage biopharmaceutical company with a proprietary technology platform focused on the development and commercialization of a novel class of specifically targeted polyclonal antibodies in the treatment of diseases associated with the gastrointestinal tract. We believe that we can address this significant unmet medical need. Our polyclonal antibodies are orally active and offer localized delivery within the gastrointestinal (“GI”) tract. As our products do not cross from the gut into the bloodstream, they potentially offer much improved safety and tolerability, without sacrificing efficacy. We currently market our flagship commercial products Travelan^® and Protectyn^® in Australia, both products are listed medicines on the Australian Register for Therapeutic Goods. Travelan^® is an over-the-counter product indicated to reduce the risk of travelers’ diarrhea and is sold in pharmacies throughout Australia. Protectyn^® is currently sold online and in health practitioner clinics and is marketed as an immune supplement to help maintain a healthy digestive function and liver. We also market Travelan^® in Canada where it is licensed as a natural health product indicated to reduce the risk of travelers’ diarrhea, and presently market Travelan^® in the U.S. as a dietary supplement for digestive tract protection.

We believe that our lead drug candidates, currently in clinical development have the potential to transform the existing treatment paradigms for moderate to severe campylobacteriosis, Enterotoxigenic Escherichia coli (ETEC) infections, travelers’ diarrhea and for Clostridiodes difficile infections.

Classification as trade receivables

Trade receivables are amounts due from customers for goods sold or services performed in the ordinary course of business. They are generally due for settlement within 30 days and therefore are all classified as current.

Trade receivables are recognised initially at the amount of consideration that is unconditional unless they contain significant financing components, when they are recognised at fair value. The group holds the trade receivables with the objective to collect the contractual cash flows and therefore measures them subsequently at amortised cost using the effective interest method.

Financial assets

The group classifies the following as financial assets recognised at fair value through profit or loss (FVPL) as part of Immuron’s strategic investment in Ateria:

	●	Immuron was entitled to 735,000 share options with a total exercise price of £1,470,000 that expired on 31 July 2023. Immuron elected not to exercise 735,000 share options during the period ending 31 December 2023.

	●	Immuron may receive up to 471,306 shares as Ateria consideration receivable based on performance targets which is deemed highly probable for the period ending 31 December 2023. Refer to Note 9 for further information.

Recognised fair value measurements

Fair value hierarchy

This section explains the judgements and estimates made in determining the fair values of the financial instruments that are recognised and measured at fair value in the financial statements. To provide an indication about the reliability of the inputs used in determining fair value, the group has classified its financial instruments into the three levels prescribed under the accounting standards. An explanation of each level follows underneath the table.

Recognised fair value measurements (continued)

Fair value hierarchy (continued)

There were no transfers between different levels for recurring fair value measurements during the period.

The group’s policy is to recognise transfers into and out of fair value hierarchy levels as at the end of the reporting period.

Level 1: The fair value of financial instruments traded in active markets (such as publicly traded derivatives and equity securities) is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the group is the current bid price. These instruments are included in level 1.

Level 2: The fair value of financial instruments that are not traded in an active market (e.g. over-thecounter derivatives) is determined using valuation techniques that maximise the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.

Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3. This is the case for unlisted equity securities.

Valuation techniques used to determine fair values

The assessed fair value of Ateria contingent consideration receivable at reporting date was determined at arm’s length using the last offered share price of £1.38 on 24 November 2023 and the expected number of shares to be received of 471,306. Given positive progress being made in establishing brand identity and sales growth, the most recent capital raising price continues to be the best determination of fair value for Ateria’s shares given that they do not trade on an active market. No reasonably possible changes would result in a material change in value.

The number of shares to be received in Ateria is dependent on the financial performance of Ateria. If Ateria achieves a revenue goal for the calendar year 2023 of above £1 million, the number of shares to be received reduces on a linear basis. No shares are received if revenue exceeds £3,191,732. At the reporting date, Immuron expects 100% of shares to be received.

7	Share-based payments

Options were granted to key management personnel in 2022 but were subject to shareholder approval that was not obtained until 21 November 2023. The options have been expensed over the vesting period from when the service period commenced in 2022 and lmmuron have revised the estimate of fair value at the grant date of 21 November 2023.The adjustment of $30,501 relates to the difference between the estimated fair value and the grant date fair value of these options. The fair value at the shareholder approval date was lower than the fair value at the estimated grant date. The assessed fair value of options at grant date was determined using the Black-Scholes option pricing model that takes into account the exercise price, term of the option, security price at grant date and expected price volatility of the underlying security, the expected dividend yield, risk-free interest rate for the term of the security and certain probability assumptions. Refer to Note 10 for further information.

Performance rights were granted to key management personnel and employees during the period for the year ended 30 June 2024. These can be settled in cash or shares and lmmuron have recognised a liability as at 31 December 2023. The performance rights are based on non-market key performance indicator (KPls). They have been expensed over the service period based on an estimate of KPls are expected to be achieved by 30 June 2024. The expense for the period ended 31 December 2023 was $124,416.

13 Basis of preparation of half-year report

This consolidated interim financial report for the half-year reporting period ended 31 December 2023 has been prepared in accordance with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Act 2001.

The consolidated financial statements of the Immuron Limited group also comply with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

These consolidated financial statements do not include all the notes of the type normally included in an annual financial report. Accordingly, this report is to be read in conjunction with the annual report for the year ended 30 June 2023 and any public announcements made by Immuron Limited during the interim reporting period in accordance with the continuous disclosure requirements of the Corporations Act 2001.

The accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period, unless otherwise stated. The Interim Financial Statements have been approved and authorised for issue by the board on 28 February 2024.

(a) Income and revenue recognition

(i) Sale of hyperimmune products

Revenue arises mainly from the sale of hyperimmune products. To determine whether to recognize revenue, the group follows the process of identifying the contract with a customer, identifying the performance obligations, determining the transaction price, allocating the transaction price to the performance obligations and recognizing revenue when performance obligations are satisfied.

Revenue from the sale of hyperimmune products is recognized at a point in time when or as the group transfers control of the assets to the customer upon delivery of the products or in the case of consignment sales when the distributor sells the product to the customer . The general standard payments terms for customers are 30 days.

There is no significant cost to obtain the contract. However, there is variable consideration due to rebates, discounts and refunds. The variable amount of consideration is allocated entirely to the distinct good that is consistent with the amount of consideration to which the group expects to be entitled in exchange for transferring the promised goods to the customer. The group offers rebates of up to 15% to some loyal customers in Australia. There are no warranties. Returns and refunds are provided where this is outlined in a customer agreement. The group does not have a formal policy in place relating to stock returns. In cases where we have a contract in place with a distributor, and that contract includes a stock return policy, we will adhere to the policy listed in the contract. For all other distributors, stock returns are negotiated on a case-by-case basis. The exception to this is where is short dated to within 3 months. In this case we will offer replacement stock or a refund.

b	complying with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Regulations 2001.

Basis for Conclusion

We conducted our review in accordance with ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity. Our responsibilities are further described in the Auditor’s responsibilities for the review of the financial report section of our report. We are independent of the Company in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audit of the annual financial report in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code.

Directors’ responsibility for the half-year financial report

The Directors of the Company are responsible for the preparation of the half-year financial report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the Directors determine is necessary to enable the preparation of the half-year financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error.

Auditor’s responsibility for the review of the financial report

Our responsibility is to express a conclusion on the half-year financial report based on our review. We conducted our review in accordance with Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity, in order to state whether, on the basis of the procedures described, we have become aware of any matter that makes us believe that the half-year financial report is not in accordance with the Corporations Act 2001 including giving a true and fair view of the Group’s financial position as at 31 December 2023 and its performance for the half-year ended on that date, and complying with Accounting Standard AASB 134 Interim Financial Reporting and the Corporations Regulations 2001.

A review of a half-year financial report consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Australian Auditing Standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.
