NEW YORK, May 09, 2022 (GLOBE NEWSWIRE) -- iBio, Inc. (NYSEA:IBIO) (“iBio” or the “Company”), a developer of next-generation biopharmaceuticals and pioneer of the sustainable FastPharming® Manufacturing System, announced today a poster presentation on IBIO-101, the Company's monoclonal antibody candidate for the treatment of solid tumors. The presentation will take place at Frontiers in Cancer Immunotherapy 2022 by the New York Academy of Sciences from May 9-11.
Preclinical evaluation of IBIO-101, produced with iBio’s FastPharming and GlycaneeringSM Systems, showed equivalent efficacy and potency compared with this IL-2 sparing anti-CD25 antibody made using traditional mammalian cell culture methods (RTX-003 from RubrYc Therapeutics, Inc.). Additionally, iBio’s proprietary afucosylation technology enabled the engineering of a more potent version without incremental intellectual property access costs. The Company now plans to advance its Glycaneered anti-CD25 monoclonal antibody for the depletion of regulatory T cells (“Tregs”) to the clinic next year.
Dillon Phan, PhD, iBio’s Vice President and Head of Early Research and Development, will present the poster, titled "Plant-Based Expression and Glyco-Engineering of Novel IL-2 Signaling Permissive Anti-CD25 Antibodies for Effective Treg Depletion in Cancer", which highlights:
- A CD25 epitope-survey using a novel artificial intelligence/machine learning platform to identify one epitope and corresponding antibodies with particularly high antibody-dependent cellular cytotoxicity (“ADCC”) activity.
- The production of a Glycaneered version of IBIO-101, which significantly increased effector function resulting from afucosylation using a deltaXT/FT N. benthamiana host compared with a fucoslyated form of the molecule.
- Binding of IBIO-101 specifically to CD25+ cancerous cells with high affinity.
- Preserved IL-2 signaling to effector T cells via pSTAT5.
- Potent ADCC activity in killing cancer cells.

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 FastPharming Manufacturing System; the ability to produce IL-2 sparing anti-CD25 antibody using the FastPharming Manufacturing System with efficacy and potency equivalent to other manufacturing systems; the ability to produce a more potent version of IL-2 sparing anti-CD25 antibody; and the ability to file an IND for the anti-CD25 monoclonal antibody. 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 the Company 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.
