Ibio (0JV0) Risk Analysis

Throughout the drug development process, we must continually demonstrate the activity, safety, and tolerability of our product candidates in order to obtain regulatory approval to further advance our clinical development, or to eventually market it. Even if any of our product candidates demonstrate adequate biologic activity and clear clinical benefit, any unacceptable side effects or adverse events, when administered alone or in the presence of other pharmaceutical products, may outweigh these potential benefits. We may observe adverse or serious adverse events or drug-drug interactions in preclinical studies or clinical trials of our clinical product candidate, which could result in the delay or termination of its development, prevent regulatory approval, or limit its market acceptance if it is ultimately approved. Adverse events caused by any of our product candidates could cause reviewing entities, clinical trial sites or regulatory authorities to interrupt, delay or halt clinical trials and could result in the denial of regulatory approval. If an unacceptable frequency or severity of adverse events are reported in any clinical trials we may conduct for our product candidates, our ability to obtain regulatory approval for such clinical product candidate may be negatively impacted. In addition, adverse events caused by any product candidate administered in combination with our product candidates could cause similar interruptions and delays, even though not caused by our product candidates. Furthermore, if any of our products are approved and then cause serious or unexpected side effects, a number of potentially significant negative consequences could result, including: - regulatory authorities may withdraw their approval of the clinical product candidate or impose restrictions on its distribution or other risk management measures;- regulatory authorities may require the addition of labeling statements, such as warnings or contraindications;- we may be required to conduct additional clinical trials;- we could be sued and held liable for injuries sustained by patients;- we could elect to discontinue the sale of the clinical product candidate; and - our reputation may suffer. Any of these events could prevent us from achieving or maintaining market acceptance of the affected clinical product candidate and could substantially increase the costs of commercialization.

We conduct, and may continue to conduct, certain clinical trials and clinical development activities in Australia. As a result, we are subject to Australian laws, regulations and regulatory authorities, including the Australian TGA, HREC and other governmental and institutional bodies that oversee clinical research. Compliance with these requirements may be complex, time-consuming and costly and may differ significantly from the regulatory requirements applicable in the United States and other jurisdictions in which we may seek marketing approval. Clinical trials conducted in Australia are subject to risks that may be outside of our control, including delays in obtaining regulatory and ethics committee approvals, changes in applicable laws, regulations or regulatory interpretations, difficulties in patient enrollment and retention, shortages of qualified investigators or clinical trial sites, and challenges associated with managing trial activities across multiple jurisdictions. In addition, Australian regulatory authorities may suspend, terminate, delay or require modifications to a clinical trial if safety concerns arise or if regulatory requirements are not satisfied. Any such actions could delay the development of our product candidates, increase our development costs and adversely affect our ability to obtain regulatory approval on a timely basis or at all. Furthermore, data generated from clinical trials conducted in Australia may be subject to additional review by the FDA and other foreign regulatory authorities. There can be no assurance that data obtained from Australian clinical trials will be accepted by the FDA or other regulators without additional studies or analyses. If regulatory authorities determine that additional clinical trials are required, or if they question the adequacy, integrity or applicability of data generated in Australia, our development timelines could be significantly extended, our costs could increase substantially, and commercialization of our product candidates could be delayed or prevented. In addition, conducting operations internationally exposes us to risks relating to currency fluctuations, cross-border data privacy requirements, supply chain disruptions, geopolitical events, changes in tax laws, employment matters and other legal and operational uncertainties. The occurrence of any of these events could adversely affect our clinical development programs, financial condition, results of operations and prospects.

Our Phase 1 clinical trial of IBIO-600 is subject to significant risks and uncertainties, including the risk that the trial may be delayed, suspended, or terminated due to adverse events, regulatory actions, or other unforeseen circumstances. Clinical trials are inherently risky, and the results of early-stage trials may not be predictive of results in later-stage trials. Even if our Phase 1 trial generates positive safety and pharmacokinetic data, there can be no assurance that IBIO-600 will demonstrate sufficient efficacy in subsequent trials to support regulatory approval. Additionally, the Phase 1 trial is being conducted in Australia under a Clinical Trial Notification scheme rather than an FDA-approved IND, and there can be no assurance that the FDA will accept data from this study to support a future U.S. IND application or marketing approval. We have engaged a CRO to manage the trial, and we are dependent on their performance to recruit participants, conduct the study in compliance with applicable regulations, and deliver reliable data. Any failure or delay by our CRO could materially impact our clinical development timeline and increase our costs. Furthermore, as a company that has only recently transitioned to clinical stage, we have limited experience managing clinical trials and may encounter unexpected challenges in trial execution, data management, regulatory interactions, or manufacturing clinical supply.

We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. The enrollment of patients depends on many factors, including: - the patient eligibility and exclusion criteria defined in the protocol;- the size of the patient population required for analysis of the trial's primary endpoints;- the willingness or availability of patients to participate in our trials;- the number and location of participating trial sites;- the proximity of patients to trial sites and any limitations on travel or access to trial sites;- the design of the trial;- our ability to recruit clinical trial investigators with the appropriate competencies and experience;- clinicians' and patients' perceptions as to the potential advantages and risks of the product candidate being studied in relation to other therapies;- our ability to obtain and maintain patient consents; and - the risk that patients enrolled in clinical trials will drop-out of the trials before completion of their involvement in the study. For example, we may not be able to continue our Phase 1 clinical trial of IBIO-600 if we are unable to locate and enroll a sufficient number of eligible overweight or obese adults in Australia to participate in the trial as required by the Australian TGA. As of the date of the filing of this Annual Report, 31 of the 32 planned participants have been enrolled in the SAD portion of the Phase 1 clinical trial of IBIO-600. Our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials in such clinical trial site. Delays in patient enrollment may result in increased costs or may affect the timing or outcome of our current Phase 1 clinical trial of IBIO-600 or future clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates. Even if we are able to enroll a sufficient number of patients in our clinical trials, if the pace of enrollment is slower than we expect, the development costs for our product candidates may increase, and the completion of our trials may be delayed or our trials could become too expensive to complete.

Any interim, initial or preliminary data or results from clinical trials, including interim top-line results and other results published from our clinical trials may materially change as more patient data become available. Preliminary, initial, interim or top-line results also remain subject to audit, validation and verification procedures that may result in the final data being materially different from the data we previously published. As a result, interim, initial or preliminary data may not be predictive of final results and should be viewed with caution until the final data are available. We may also arrive at different conclusions, or considerations may qualify such results, once we have received and fully evaluated additional data. Differences between preliminary, initial or interim data and final data could adversely affect our business. There is a high failure rate for drugs and biologics proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical development even after achieving promising results in earlier studies, and we cannot be certain that we will not face similar setbacks. Many drugs have failed to replicate efficacy and safety results in larger or more complex later stage trials. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain regulatory approval. If we fail to produce positive results in our ongoing and planned preclinical studies and clinical trials with IBIO-600, IBIO-610 or any of our other product candidates, or if a regulatory authority interprets and analyzes the results as not positive, the development timeline and regulatory approval and commercialization prospects for our product candidates, and, correspondingly, our business and financial prospects, may be materially adversely affected.

We recently became a clinical stage biopharmaceutical company leveraging the power of Artificial Intelligence (AI) for the development of precision antibodies for obesity, cardiometabolic and cardiopulmonary diseases. Prior to August 23, 2021, when we entered into a series of agreements with RubrYc, we were focused on our CDMO business. We have never generated any product revenue from the development of precision antibodies, do not expect to generate revenue in the near future and do not have any products approved for sale. Our operations to date have been primarily focused on developing our product candidates. In June 2026, we dosed the first participant in a Phase 1 clinical trial of IBIO-600 in Australia; however, we have not yet completed any clinical trials. Consequently, predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing product candidates. All of our existing product candidates are in early stages of development and will require extensive additional clinical evaluation, regulatory review and approval, significant marketing efforts and substantial investment before they could provide us with any revenue.

We have a limited number of product candidates, with IBIO-600 in a Phase 1 clinical trial and our other candidates in preclinical development, focused primarily on obesity, cardiometabolic and cardiopulmonary diseases. During fiscal year 2026, we completed a strategic pivot away from immune-oncology, fully impairing our IBIO-101 asset and ceasing active marketing of our oncology programs. As a result, our pipeline is now concentrated in a single therapeutic area, which increases our exposure to setbacks in that area. It is possible that we may never be able to develop a marketable product candidate. We expect that a substantial portion of our efforts and expenditures over the next few years will be devoted to our product candidates in the cardiometabolic and obesity fields. Accordingly, our business currently depends heavily on the successful development, regulatory approval and commercialization of these product candidates, which may not receive regulatory approval or be successfully commercialized even if regulatory approval is received. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of product candidates are and will remain subject to extensive regulation by the FDA and other regulatory authorities in the United States and other countries that each have differing regulations. We are not permitted to market any product in the United States unless and until we receive approval from the FDA, or in any foreign countries unless and until we receive the requisite approval from regulatory authorities in such countries. We have never submitted an NDA or BLA to the FDA or comparable applications to other regulatory authorities and do not expect to be in a position to do so for the foreseeable future. Obtaining approval of an NDA or BLA is an extensive, lengthy, expensive, and inherently uncertain process, and the FDA may delay, limit or deny approval of its product for many reasons. Because we have limited financial and managerial resources, our focus is limited to the development of multiple product candidates. As a result, we may forego or delay pursuit of opportunities with other technologies or product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending and the spending of our clients and collaborators may not yield any commercially viable products. We have based our research and development efforts largely on our technologies and product candidates derived from such technologies. Notwithstanding our large investment to date and anticipated future expenditures in these technologies, we have not yet developed, and may never successfully develop, any marketed products using these technologies. As a result, we may fail to address or develop product candidates based on other scientific approaches that may offer greater commercial potential or for which there is a greater likelihood of success. We also may not be successful in our efforts to identify or discover additional product candidates using our technologies. Research programs to identify new product candidates require substantial technical, financial, and human resources. These research programs may initially show promise in identifying potential product candidates yet fail to yield product candidates for clinical development.

Because we have limited financial and managerial resources, we focus on specific product candidates derived from or enhanced by our technologies or that have been identified and partially developed by our clients or collaborators. As a result, we may forego or delay pursuit of opportunities with other technologies or product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending and the spending of our clients and collaborators may not yield any commercially viable products. We have based our research and development efforts largely on our technologies and product candidates derived from such technologies. Notwithstanding our large investment to date and anticipated future expenditures in these technologies, we have not yet developed, and may never successfully develop, any marketed products using these technologies. As a result, we may fail to address or develop product candidates based on other scientific approaches that may offer greater commercial potential or for which there is a greater likelihood of success. We also may not be successful in our efforts to identify or discover additional product candidates using our technologies. Research programs to identify new product candidates require substantial technical, financial, and human resources. These research programs may initially show promise in identifying potential product candidates yet fail to yield product candidates for clinical development. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements on terms less favorable to us than possible.

All but one of our product candidates are still in preclinical development. Our ability to generate product sales revenues for our own products, which we do not expect will occur for many years, will depend heavily on the successful development and eventual commercialization of our product candidates. The success of our product candidates will depend on several factors, including the following: - completion of preclinical studies and clinical trials with positive results;- receipt of marketing approvals from applicable regulatory authorities;- obtaining and maintaining patent and trade secret protection and regulatory exclusivity, which may exceed patent exclusivity, for our product candidates;- making arrangements with third-party manufacturers for commercial manufacturing capabilities;- launching commercial sales of our products, if and when approved, whether alone or in collaboration with others;- successfully maintaining existing collaborations and entering into new ones throughout the development process as appropriate, from preclinical studies through to commercialization;- acceptance of the products, if and when approved, by patients, the medical community and third-party payors;- effectively competing with other products;- obtaining and maintaining coverage and adequate reimbursement by third-party payors, including government payors, for any products we successfully develop;- protecting our rights in our intellectual property portfolio; and - maintaining a continued acceptable safety profile of the products following approval. If we or our collaborators do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully develop and commercialize our product candidates, which would materially harm our business. The risks associated with our product candidates not proceeding through clinical development is high. We expect it will be many years before we commercialize any product candidate, if ever. The product candidates we are developing are unproven, which makes it difficult to accurately predict the challenges we may face with respect to our product candidates as they proceed through development. It is also impossible to predict whether our clinical trials will proceed through registrational trials and when or if any of our product candidates will receive regulatory approval. To obtain the requisite regulatory approvals to commercialize any product candidates, we must demonstrate through extensive preclinical studies and lengthy, complex and expensive clinical trials that our product candidates are safe and effective in humans. We commenced our first human clinical trial in June 2026. Clinical testing can take many years to complete, and its outcome is inherently uncertain. Commencing any future clinical trials is subject to finalizing the trial design and submitting an application to the FDA or a comparable foreign regulatory authority. Even after we make our submission, the FDA or comparable foreign regulatory authority could disagree that we have satisfied their requirements to commence our clinical trials or disagree with our trial design, which may require us to complete additional studies or trials, amend our protocols or impose stricter conditions on the commencement of clinical trials. While we believe that data we and our collaborators have obtained from preclinical studies of iBio technology-derived and iBio technology-enhanced product candidates has validated these technologies, our technologies have not yet, and may never lead to, approvable or marketable products. Even if we are successful in further validating our technologies and continuing to build our pipeline, the potential product candidates that we identify may not be suitable for clinical development for many possible reasons, including harmful side effects, limited efficacy or other characteristics that indicate that such product candidates are unlikely to be products that will receive marketing approval and achieve market acceptance. If we and our collaborators do not successfully develop and commercialize product candidates based upon our technologies, we will not obtain product or collaboration revenues in future periods, which likely would result in significant harm to our financial position and adversely affect our stock price.

Human clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time-consuming. We estimate that clinical trials for our product candidates would take at least several years to complete. Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical trials. Commencement and completion of clinical trials may be delayed by several factors, including: - obtaining an IND application with the FDA or foreign equivalent to commence clinical trials;- identification of, and acceptable arrangements with, one or more clinical sites;- obtaining IRB or Ethics Committee ("EC") approval to commence clinical trials;- unforeseen safety issues;- determination of dosing;- lack of effectiveness during clinical trials;- slower than expected rates of patient recruitment;- inability to monitor patients adequately during or after treatment;- lower than expected rates of patient completion of clinical trials;- inability to obtain supply of our drug candidate in a timely manner;- inability or unwillingness of medical investigators to follow our clinical protocols; and - unwillingness of the FDA or foreign equivalent, or IRBs/ECs to permit the clinical trials to be initiated. In addition, we, IRBs/ECs, the FDA, the Australian TGA or other regulatory authorities may suspend our clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or if IRBs/ECs, the FDA, the Australian TGA or other regulatory agencies find deficiencies in our submissions or conduct of our trials.

Preclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and has an uncertain outcome. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical trial do not necessarily predict final results. We and our licensees may experience numerous unforeseen events during, or as a result of, preclinical testing and the clinical trial process that could delay or prevent the commercialization of product candidates based on our iBio technologies, including the following: - Preclinical or clinical trials may produce negative or inconclusive results, which may require additional preclinical testing, additional clinical trials or the abandonment of projects that we expect to be promising. For example, promising animal data may be obtained about the anticipated efficacy of a therapeutic protein product candidate and then human tests may not result in such an effect. In addition, unexpected safety concerns may be encountered that would require further testing even if the therapeutic protein product candidate produced an otherwise favorable response in human subjects. - Initial clinical results may not be supported by further or more extensive clinical trials. For example, a licensee may obtain data that suggest a desirable immune response from a product candidate in a small human study, but when tests are conducted on larger numbers of people, the same extent of immune response may not occur. If the immune response generated by a product candidate is too low or occurs in too few treated individuals, then the product candidate will have no commercial value. - Enrollment in any clinical trials that we or our licensee's conduct may be slower than projected, resulting in significant delays. The cost of conducting a clinical trial increases as the time required to enroll adequate numbers of human subjects to obtain meaningful results increases. Enrollment in a clinical trial can be a slower-than-anticipated process because of competition from other clinical trials, because the study is not of interest to qualified subjects, or because the stringency of requirements for enrollment limits the number of people who are eligible to participate in the clinical trial. - We or our potential licensees might have to suspend or terminate clinical trials if the participating subjects are being exposed to unacceptable health risks. Animal tests do not always adequately predict potential safety risks to human subjects. The risk of any candidate product is unknown until it is tested in human subjects, and if subjects experience adverse events during the clinical trial, the trial may have to be suspended and modified or terminated entirely. - Regulators or institutional review boards may suspend or terminate clinical research for various reasons, including safety concerns or noncompliance with regulatory requirements. - Any regulatory approval ultimately obtained may be limited or subject to restrictions or post-approval commitments that render the product not commercially viable. - The effects of iBio technology-derived or iBio technology-enhanced product candidates may not be the desired effects or may include undesirable side effects. Significant clinical trial delays could allow our competitors to bring products to market before we or our licensees do and impair our ability to commercialize our technologies and product candidates based on our technologies. Poor clinical trial results or delays may make it impossible to license a product candidate, or reduce its attractiveness to prospective licensees, so that we will be unable to successfully develop and commercialize such a product candidate. Clinical trials are risky, lengthy, and expensive. We will incur substantial expense for, and devote significant time and resources to, preclinical testing and clinical trials, yet we cannot be certain that these tests and trials will demonstrate that a product candidate is effective and well-tolerated or will ever support its approval and commercial sale. For example, clinical trials require adequate supplies of clinical trial material and sufficient patient enrollment to power the trial. Delays in patient enrollment can result in increased costs and longer development times. Even if we, or a licensee or collaborator, if applicable, successfully complete clinical trials for our clinical product candidate, we or they might not file the required regulatory submissions in a timely manner and may not receive marketing approval for the clinical product candidate. We cannot assure you that our clinical product candidate will successfully progress further through the drug development process or will ultimately result in an approved and commercially viable product.

We commenced independent operations in 2008, and our operations to date have included organizing and staffing our company, business planning, raising capital, acquiring and developing our proprietary technologies, running a contract development and manufacturing organization ("CDMO"), identifying potential product candidates and undertaking, in house and through third parties, preclinical trials and clinical trials of product candidates derived from our technologies. Prior to the end of calendar year 2022, we shifted our focus away from generating revenue as a CDMO service provider to the development of vaccines and therapeutics for commercialization and thereafter to immune-oncology therapeutics.  Our current focus is on precision antibodies for obesity, cardiometabolic and cardiopulmonary diseases. In June 2026, we dosed the first participant in a Phase 1 clinical trial of IBIO-600, our long-acting anti-myostatin antibody, in Australia. With the exception of IBIO-600, all of our other  product candidates are still in preclinical development and there is a risk that we will be unsuccessful in developing or commercializing any product candidates. We have not yet demonstrated our ability to successfully complete any clinical trials, obtain regulatory approvals, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. Consequently, any conclusion you reach about our future success or viability may not be as predictive as it might be if we had a longer operating history. Even if we receive regulatory approval for the sale of any of our product candidates, we do not know when we will begin to generate significant revenue from such product candidates, if at all. Our ability to generate revenue depends on a number of factors, including our ability to: - set an acceptable price for our products and obtain coverage and adequate reimbursement from third-party payors;- establish sales, marketing, manufacturing and distribution systems; add operational, financial and management information systems and personnel, including personnel to support our clinical, manufacturing and planned future clinical development and commercialization efforts and operations as a public company;- manufacture commercial quantities of product candidates at acceptable cost levels;- achieve broad market acceptance of our product candidates in the medical community and with third-party payors and consumers;- attract and retain an experienced management and advisory team;- launch commercial sales of our products, whether alone or in collaboration with others; and - maintain, expand and protect our intellectual property portfolio. Because of the numerous risks and uncertainties associated with development and manufacturing product candidates, we are unable to predict if we will generate significant revenue. If we cannot successfully execute on any of the factors listed above, our business may not succeed, and we may never generate significant revenue.
