- Results in new study showed INO-4800 vaccine-induced neutralizing antibodies and T cell responses against UK, South African and Brazilian variant strains
- Paper entitled, “INO-4800 DNA Vaccine Induces Neutralizing Antibodies and T cell Activity Against Global SARS-CoV-2 Variants,” submitted for peer review and available via preprint in bioRxiv
INOVIO today announced the results of a study focusing on the human immune responses induced by INOVIO’s DNA vaccine candidate for COVID-19, INO-4800, against variants of concern. The results showed that INO-4800 induced a robust T cell response against all spike protein variants tested, which the company believes will be key in providing protection against SARS-CoV-2 variants, in addition to providing similar levels of neutralizing activity against both the UK and Brazilian variants as those against the original strain. The study, entitled “INO-4800 DNA Vaccine Induces Neutralizing Antibodies and T cell Activity Against Global SARS-CoV-2 Variants,” has been submitted for peer review and can be viewed at https://www.biorxiv.org/content/10.1101/2021.04.14.439719v1.
Dr. J. Joseph Kim, INOVIO’s President & CEO, said, “These results are consistent with our expectation that INO-4800, which was found to be well-tolerated and able to produce a balanced immune response in our Phase 1 trial, is able to generate both neutralizing antibodies and robust T cell responses – both of which will be essential to protect against the emerging variants of concern.”
Regarding INO-4800 development Dr. Kim said, “We will report Phase 2 results in 2Q, and, with FDA concurrence, expect to move into Phase 3 in the second quarter of this year. Our COVID vaccine’s projected safety profile, its stability at room temperature for more than a year, and likely ability to safely boost numerous times positions INOVIO’s COVID-19 vaccine as an important factor in addressing the virus in its pandemic and endemic states.”
