– AI-powered technology enables rapid, simultaneous progress of antibodies against challenging targets –
The anti-EGFRvIII antibody was specially engineered to enhance its ability to attack cancer cells and has proven effective in a mouse model for head and neck cancer. In preclinical studies, iBio’s anti-EGFRvIII antibody demonstrated a 43 percent reduction in tumor growth compared to untreated animals. iBio developed the antibody using its patented AI epitope steering technology. This innovative approach allows iBio to target a specific variant of the Epidermal Growth Factor Receptor (EGFR) found in tumors without affecting the normal version of the receptor present in healthy tissue. By focusing solely on the tumor-specific variant, iBio aims to reduce potential side effects.
In addition to the anti-EGFR program, iBio’s CCR8 antibody has proven effective in a mouse model for colon cancer. Preclinical studies show the anti-CCR8 molecule inhibited tumor growth and achieved a 22 percent reduction in tumor size compared to its pre-treatment dimensions. Using its patented AI epitope steering platform, iBio specifically engineered the anti-CCR8 molecule to enhance its ability to attack cancer cells without affecting its close relative, CCR4, even though their binding regions are highly similar. This selective targeting demonstrates the power of iBio's epitope steering platform and is believed to minimize potential side effects.
In a recent study involving a humanized mouse model of squamous cell carcinoma, iBio’s TROP-2 x CD3 bi-specific antibody demonstrated a significant 36 percent reduction in tumor size within just 14 days after tumor implantation, and after only a single dose. iBio's TROP-2 x CD3 was engineered using its proprietary EngageTx™ T-cell engager antibody platform, which represents a cutting-edge approach to developing next-generation bispecific antibodies for immuno-oncology applications. TROP-2 x CD3 is a bispecific antibody targeting an overexpressed cell surface protein in multiple solid tumors, including breast, lung, colorectal, and pancreatic cancers. iBio is currently exploring whether the molecule also shows efficacy in other solid tumors.

FORWARD-LOOKING STATEMENTS
Certain statements in this press release constitute "forward-looking statements" within the meaning of the federal securities laws. Words such as "may," "might," "will," "should," "believe," "expect," "anticipate," "estimate," "continue," "predict," "forecast," "project," "plan," "intend" or similar expressions, or statements regarding intent, belief, or current expectations, are forward-looking statements. These forward-looking statements are based upon current estimates and assumptions and include statements regarding the Company’s anti-EGFRvIII antibody reducing potential side effects by focusing solely on the tumor-specific variant and the potential to further develop and initiate IND-enabling studies for all three molecules to support the continued advancement of the Company’s therapeutic pre-clinical pipeline. While the Company believes these forward-looking statements are reasonable, undue reliance should not be placed on any such forward-looking statements, which are based on information available to us on the date of this release. These forward-looking statements are subject to various risks and uncertainties, many of which are difficult to predict that could cause actual results to differ materially from current expectations and assumptions from those set forth or implied by any forward-looking statements. Important factors that could cause actual results to differ materially from current expectations include, among others, the Company’s ability to generate successful results from the molecules, including reducing side effects, continue to execute its growth strategy; its ability to obtain regulatory approvals for commercialization of its product candidates, or to comply with ongoing regulatory requirements; regulatory limitations relating to its ability to promote or commercialize its product candidates for specific indications; acceptance of its product candidates in the marketplace and the successful development, marketing or sale of products; its ability to maintain its license agreements; the continued maintenance and growth of its patent estate; its ability to obtain or maintain the capital or grants necessary to fund its research and development activities and whether the Company will incur unforeseen expenses or liabilities or other market factors; successful compliance with governmental regulations applicable to its manufacturing facility; competition; its ability to retain its key employees or maintain its NYSE American listing; and the other factors discussed in the Company’s filings with the
