iBio Reports Progress on its Bio-Better Rituximab Collaboration with CC-Pharming

- Presentation Demonstrates Advantages of iBio’s Recently Launched FastGlycaneering Development Service™ -

NEW YORK, Dec. 16, 2019 (GLOBE NEWSWIRE) -- iBio, Inc. (NYSE AMERICAN:IBIO) presented results of the application of its new FastGlycaneering Development Service™ to enhance potency of recombinant proteins at last week’s Antibody Engineering & Therapeutics conference in San Diego, CA. Specifically, the presented data demonstrated  the ability to deploy iBio’s glycan engineering technologies and plant-based manufacturing platform to rapidly develop and produce biobetters, such as the biobetter rituximab (“iBio Rituximab”) product candidate currently being developed in collaboration with CC-Pharming Ltd.

Dr. Sylvain Marcel, iBio’s Vice President of Protein Expression Sciences, highlighted laboratory results showing how iBio’s FastGlycaneering Technology enables greater N-linked glycosylation customization and control. In the case of iBio Rituximab, antibody dependent cellular cytotoxicity was increased 30-fold; potency, as measured by half maximal effective concentration, was substantially improved versus the control antibody; and iBio’s glycan engineering methods were shown to be capable of producing antibodies with more homogeneous and fully human glycosylation patterns.

“This study demonstrated that our complementary glycan engineering technology can improve the activity of therapeutic antibodies, which is instrumental in the development of antibodies with higher potency,” stated Dr. Marcel. “These data represent a very positive development within our collaboration with CC-Pharming and, in addition, highlight iBio’s ability to produce antibodies with more homogeneous and humanized glycosylation patterns, which can help our other clients and partners achieve their target product profiles.”

In addition to joint work on a biobetter rituximab, iBio and CC-Pharming are undertaking joint product assessments in other categories that, in some cases, may reach the commercial stage faster than is possible with therapeutic antibodies. The companies expect to use iBio’s FastGlycaneering Technology for any glycoproteins selected from the initial candidate pool for advancement to commercial development.

In August 2019, iBio granted to CC-Pharming an exclusive, royalty-bearing commercial license to iBio Rituximab product candidates for the territory of China, as well as a research license to iBio’s FastPharming System™ and know-how for the evaluation of multiple product opportunities.
