iBio Provides Update on Next-Gen COVID-19 Development

– Manufacture of the first batch of drug substance under cGMP conditions –

– Analysis of data from the ongoing challenge study –

BRYAN, Texas, Aug. 16, 2022 (GLOBE NEWSWIRE) — iBio, Inc. (NYSEA: IBIO) (“iBio” or the “Company”), a developer of next-generation biopharmaceuticals and pioneer in sustainability FastPharming® Manufacturing System, today provided an update on IBIO-202, its next-generation vaccine candidate under development for multivariate COVID-19 disease.

The Company recently completed its first manufacturing cycle of its proprietary core antigen under cGMP conditions using its FastPharming System. Unlike commercially available first-generation COVID vaccines that seek to provide immunity by presenting an antigen based on the spike (“S”) protein that mutates frequently – resulting in periods of waning immunity and the spread new variants1 – IBIO-202 uses part of the nucleocapsid (“N”) protein, which is more highly conserved.2 The newly produced antigen N is currently undergoing release testing and if it clears, it is intended for use in clinical studies of IBIO-202.

“This is another important step in our mission to develop a ‘last dose’, not a ‘next dose’ of a COVID-19 vaccine,” said Tom Isett, chief executive officer of iBio. . “We believe there is a substantial unmet need for a vaccine that protects against existing – and potentially new – variants and for longer periods of time. While currently available advanced protein-based COVID-19 vaccines have undoubtedly prevented serious illness and death for millions of people, hospitalizations and deaths have nevertheless recently increased again in the United States.3 This is mainly due to specific mutations in the virus’s spike protein, such as those associated with the BA.5 variant, which cause existing vaccines to offer less protection or shorter periods of immunity.

On July 26 Future of COVID Vaccines Summit, these recent developments prompted Raj Panjabi, MD, MPH, director of the White House Office of Pandemic Preparedness, to state that “predicting where the virus will go is difficult, but so is asking people to get vaccinated two or three times a year. year. It’s a huge challenge. So we need long-lasting vaccines. We need vaccines that provide broader, longer-lasting protection. We need vaccines that offer protection against multiple variants. Ultimately, we need vaccines that can protect us no matter what mother nature throws at us.”3

Last month, Senate Appropriations Committee Chairman Patrick Leahy (D-VT), in partnership with the chairs of the subcommittees responsible for national health care and global health, Patty Murray (D-WA) and Chris Coons (D-DE), presented an additional funding bill of $21 billion to provide the resources needed to prepare for the next phase of the COVID-19 pandemic and fight other emerging infectious diseases. This important legislation includes $750 million for next-generation COVID-19 vaccines to protect against worrisome variants of today and tomorrow and underscores the need to sustain and increase domestic manufacturing capacity.

“We continue to engage directly with these members and other members of Congress about funding opportunities for next-generation COVID-19 vaccines,” Isett added. “In addition, we regularly maintain direct dialogue with administration officials about the need and value of funding iBio’s work in this area.”

In addition, iBio has confirmed that it is in the process of compiling and analyzing initial data from IBIO-202’s Enabling New Drug (“IND”) challenge studies.

About iBio’s COVID-19 Vaccine Development Program

In November 2020, iBio began exploring a second-generation N-protein-based COVID-19 vaccine program. In July 2021, iBio announced positive results from variable-dose preclinical studies that demonstrated that IBIO-202 could generate a robust, antigen-specific memory T cell response. Additionally, T-cell priming was achieved by intramuscular and intranasal administration, allowing further exploration of multiple routes of administration and their respective advantages. In September 2021, iBio submitted a pre-IND dossier for IBIO-202 to the FDA. In November 2021, the company announced that it had entered into a collaboration agreement with a leading innovator in the field of microarray patch systems to assess the feasibility of intradermal delivery of a COVID-19 vaccine antigen. Based on comments received from the FDA, in January 2022 iBio announced that it was pursuing IND-Enabling studies for IBIO-202, administered intramuscularly. Today, the company announced that it has completed its first production of its proprietary core antigen under cGMP conditions in support of the production of drug substance IBIO-202. Further information on the COVID-19 vaccination program is available on the Company’s website.

The scientific rationale for targeting the N protein of SARS-CoV-2

iBio believes the N protein represents an important target for next-generation COVID-19 vaccines for several reasons. First, the N protein is abundantly expressed during infection and contains several immunogenic epitopes. Second, protein N is more highly conserved than protein S and therefore new variants may be less likely to escape vaccine protection. Third, research has shown that protein N appears to be significantly more effective than protein S in stimulating the activation of antibody-dependent natural killer cells, a critical component of the adaptive immune response that the SARS-CoV-2 virus attempts to mount. ‘to avoid.2,4.5,6,7
