Vaxart announced today that it received a project award valued at up to $453 million through the Rapid Response Partnership Vehicle (RRPV). The RRPV is a Consortium funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) in the U.S. Department of Health and Human Services (HHS).
The funds will be used to conduct a Phase 2b comparative study evaluating Vaxart’s oral pill COVID-19 vaccine candidate against a U.S. Food and Drug Administration (FDA)-approved mRNA vaccine comparator. In preparation for the trial, Vaxart created and manufactured under Good Manufacturing Practice (GMP) standards a next-generation oral COVID-19 vaccine tablet candidate that — based on preclinical data — is more potent than Vaxart’s prior COVID-19 vaccine constructs.
Funding under the award will be provided in two parts with approximately $65.7 million available immediately to continue study start-up activities, and the remainder of approximately $387.2 million provided when Vaxart and BARDA have determined that the study may further proceed and paid over the course of the study. Currently, Vaxart anticipates initiating enrollment as early as summer 2024. An interim analysis for vaccine efficacy compared to an approved mRNA comparator may occur as early as the first quarter of 2025.
“We are grateful to BARDA for this funding, which will enable Vaxart to conduct a Phase 2b trial for our COVID-19 oral pill vaccine candidate. This trial will evaluate whether our oral pill vaccine candidate compares favorably against an approved mRNA injectable vaccine,” said Dr. James F. Cummings, Vaxart’s Chief Medical Officer. “We are excited to explore the results of this head-to-head comparison. Previous research showed that our earlier COVID-19 vaccine constructs triggered long-lasting immune responses and induced a cross-reactive immunogenic response against all tested SARS-CoV-2 variants.”
“Vaccine delivery has relied primarily on injection for more than 150 years. This funding from BARDA will assist us in determining whether we can bring a transformational, next-generation approach to global vaccination,” said Steven Lo, Vaxart’s Chief Executive Officer. “We believe our oral pill vaccine platform can better meet societal needs not just for COVID-19, which is now in the endemic phase, but for other infectious diseases that present significant endemic and pandemic threats.”
Vaxart was the first U.S. company to complete a Phase 2 clinical trial of an oral vaccine for COVID-19. In earlier clinical trials, Vaxart demonstrated its COVID-19 vaccine candidates generated robust cross-reactive mucosal IgA responses, boosted immune responses to existing COVID-19 vaccines, increased neutralizing antibodies against Omicron 4/5, and had a benign tolerability profile.
Funding for this award was received under Project NextGen, a $5 billion initiative by HHS to develop new, innovative vaccines and therapeutics that provide broader and more durable protection against COVID-19 than the first generation COVID-19 vaccines and medicines. This project has been funded with federal funds from HHS; ASPR; BARDA, under Other Transaction (OT) number 75A50123D00005.
