Vaxxinity Initiates Rolling Submission for UB-612 COVID-19 Vaccine with MHRA (UK)

September 12, 2022

DALLAS, Sept. 12, 2022 (GLOBE NEWSWIRE) -- Vaxxinity, Inc. (Nasdaq: VAXX), a U.S. company pioneering the development of a new class of immunotherapeutic vaccines, today announced that it has initiated a rolling submission to the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom for conditional marketing authorization of its UB-612 COVID-19 vaccine as a heterologous boost to authorized primary series vaccines. UB-612 is currently being assessed in a Phase 3 pivotal trial as a booster vaccine for subjects who have received primary immunization with mRNA, adenovirus vector, or inactivated virus vaccines. Vaxxinity reiterates its plan to have a topline readout of the Phase 3 trial in the fourth quarter of 2022.

“Authorizations by stringent regulatory authorities such as the MHRA could open the pathway for UB-612 to reach countries with high unmet needs,” said Mei Mei Hu, CEO of Vaxxinity. “Because so many low and middle income (LMIC) countries look to stringent regulators' decisions as a reference, we anticipate that MHRA authorization, if achieved, could ultimately enable Vaxxinity to market UB-612 in a number of LMIC countries across the globe, which is the heart of Vaxxinity’s mission. Additionally, this authorization is a pathway to grant WHO emergency use listing (EUL), which would provide another option for getting UB-612 to countries through the COVAX program.”

About UB-612

UB-612 is the first multitope subunit protein/peptide-based vaccine candidate for SARS-CoV-2, which is designed to activate both B- and T-cell arms of the immune system directed against multiple structural viral antigens. Phase 1 and Phase 2 trials of UB-612 conducted in ~4000 participants have shown UB-612 to be well tolerated with no vaccine-related serious adverse events. The most striking findings were induction of long-lasting humoral and T-cell immunity, and a strong booster memory recall inducing high levels of neutralizing antibodies against Delta, Omicron, and other SARS-CoV-2 variants. UB-612 is now in a pivotal Phase 3 trial. More details on the trial can be found at using Identifier NCT05293665.
