POP Biotechnologies Announces Phase 3 Trial Interim Results Published for COVID-19 Vaccine Based on POP BIO SNAP(TM)

BUFFALO, NY / ACCESSWIRE / September 27, 2024 / POP Biotechnologies (POP BIO), a Buffalo, NY-based biopharmaceutical company, is pleased to announce the publication of positive findings in a peer-reviewed paper in the Journal of Medical Virology entitled “Interim safety and immunogenicity analysis of the EuCorVac-19 COVID-19 vaccine in a Phase 3 randomized, observer-blind, immunobridging trial in the Philippines“.

Developed by POP BIO’s partner EuBiologics of South Korea, the COVID-19 vaccine, EuCorVac-19 (ECV-19), demonstrated promising safety and immunogenicity in a large-scale Phase 3 clinical trial conducted in the Philippines. Developed as a recombinant vaccine displaying the receptor binding domain (RBD) of the SARS-CoV-2 virus on immunogenic liposomes, ECV-19 is designed to generate an immune response targeted against the RBD while maintaining a favorable safety profile. The vaccine utilizes POP BIO’s spontaneous nanoliposome antigen particle (POP BIO SNAP™) technology to display the RBD on the surface of nanoparticles, thereby enhancing vaccine efficacy.

The study, involving 2,600 participants, compared ECV-19 to the COVISHIELD™ adenoviral-vectored vaccine. Participants were randomly assigned to receive either vaccine, following a two-dose regimen spaced four weeks apart. Interim results indicate that ECV-19 not only produced significantly higher levels of neutralizing antibodies but also showed a reduced incidence of mild side effects after the first dose.

“ECV-19 elicited a strong immune response, with a higher seroresponse rate and greater neutralizing antibody levels against both the original Wuhan strain and the Omicron variant,” said lead author Jonathan Lovell, a cofounder of POP BIO and a professor of Biomedical Engineering at the University at Buffalo. “These findings suggest that ECV-19 could be a tool in the ongoing fight against COVID-19 but also establish proof of principle for the underlying liposome-display of protein antigens.”

The interim analysis also highlighted that ECV-19 maintained a favorable safety profile, with fewer reported cases of localized and systemic side effects compared to the CS vaccine after the initial dose.

A EuBiologics official said: “Based on the clinical results, the process for registration is currently underway in the Philippines. Moving forward, we can update the COVID-19 vaccine by simply replacing the antigen, depending on strategic decisions. With the platform technology now validated, we expect to accelerate the development of vaccines not only for COVID-19 but also for other indications, including RSV and HZV, both in Phase 1 testing, as well as Alzheimer’s Disease.”

Further analysis will provide additional insights into the long-term protection offered by ECV-19. The trial is registered on ClinicalTrials.gov (NCT05572879).
