iBio Inc., a biotech innovator and biologics contract manufacturing organization, has selected IBIO-201, its LicKM-ubunit vaccine, as its leading candidate for the prevention of SARS-CoV-2 infection.
 
iBio previously announced that preclinical immunization studies with IBIO-200 and IBIO-201, combined with select adjuvants from the Infectious Disease Research Institute (IDRI), induced anti-SARS-CoV-2 antibodies. Additional data from cell-based pseudovirus neutralization assay testing demonstrate that IBIO-201 induced the production of more anti-spike neutralizing antibodies than IBIO-200 in immunized mice.
 
“Our decision to evaluate IBIO-200 and IBIO-201 in tandem, and in combination with multiple adjuvants, proved beneficial given the results observed with IBIO-201 in preclinical studies,” said Tom Isett, chairman & CEO of iBio. “While IBIO-201 produced significantly higher anti-spike neutralizing antibody titers than IBIO-200, we are still encouraged by the potential of IBIO-200.”
 
Isett continued, “We plan to conduct more focused studies on each of IBIO-200 and IBIO-201, with the goal of advancing IBIO-201 to toxicology studies ahead of planned clinical development. Meanwhile, we intend to continue preclinical development of IBIO-200 and our virus-like particle platform as a potential ‘plug-and-play’ vaccine development system.”
 
iBio continues to work with IDRI and the Texas A&M University System, and expects to engage additional collaborators for further characterization and testing of IBIO-201 prior to performing GLP toxicology studies.
