April 6, 2022; OSLO, Norway and DALLAS, USA: The Coalition for Epidemic Preparedness Innovations (CEPI) and Vaxxinity, Inc. (Nasdaq: VAXX), a US company pioneering the development of a new class of immunotherapeutic vaccines, today announced that they will co-fund the ongoing global pivotal Phase 3 clinical trial of Vaxxinity’s next generation UB-612 COVID-19 vaccine candidate as a heterologous – or ‘mix-and-match’ – booster dose. CEPI will provide up to $9.25m in funding.
The Phase 3 trial, which began in the US earlier this year, is evaluating the ability of UB-612 to boost COVID-19 immunity against the original strain and multiple variants of concern including Omicron – in people aged 16 years or older, who have been previously immunized with an authorized COVID-19 vaccine. Prior to joining the trial, participants will have received a primary regimen of one of the vaccines developed by Oxford- AstraZeneca, Pfizer-BioNTech, Sinopharm, or Sinovac, all of which are being distributed by COVAX, which primarily supplies to low- and middle-income countries (LMICs). Participants are being assessed for safety and immunogenicity after a single booster dose of UB-612, or a homologous booster (i.e., a booster dose of the same vaccine the participant has received before), enabling comparisons between UB-612 and other regimens. Details on the Phase 3 UB-612-305 clinical trial can be found at clinicaltrials.gov using Identifier NCT05293665.
Approximately 1,000 healthy adults will take part in the Vaxxinity-sponsored multi-center international trial, with the first subjects already dosed in the US. The primary immunogenicity analyses will be available in the second half of 2022. If successful, this trial may enable global authorizations, including in high income countries and LMICs.
Data on mix-and-match combinations of vaccines – like those being assessed in this trial – will contribute to the design of flexible vaccination strategies aimed at controlling COVID-19 and combatting emerging SARS-CoV-2 variants. UB-612 can be manufactured at scale and data generated so far support storage conditions that potentially make it especially suitable for use in LMICs. In line with CEPI’s Equitable Access Policy, all data from the clinical trial will be shared through open-access publications and via scientific meetings to ensure that all can benefit from the research, and that the data can be used to inform the recommendations of policy makers and regulatory authorities on the use of COVID-19 vaccines.

Expanding access to COVID-19 vaccines by filling R&D gaps
This is the latest programme to be funded in response to a CEPI Call for Proposals launched in January 2021 which aims to address current gaps in our clinical knowledge of vaccine performance both now and in the long term, in order to expand access to COVID-19 vaccines as part of the global vaccination rollout. Examples of such gaps include assessment of the safety and effectiveness of COVID-19 vaccines in pregnant women, infants and children, and immunocompromised populations, as well as studies on booster doses, length of vaccine efficacy, mix-and-match strategies, and dosing intervals. In response to this Call for Proposals, CEPI is also funding a study of COVID-19 vaccines in immunosuppressed and transplant patients, a project to expand access to BBIBP-CorV in Africa, a clinical trial of mix-and-match combinations of vaccines in Pakistan, and a mix-and-match booster study in Taipei. In addition, CEPI has previously announced funding to support a mix-and-match study led by the University of Oxford, and is supporting trials to evaluate fractional COVID-19 booster shots in multiple countries.
This work forms part of CEPI’s next 5-year plan, published in March 2021, which aims to reduce or even eliminate the future risk of pandemics and epidemics. As part of this plan CEPI is working to strengthen our defences against COVID-19 and reduce the risk of future coronavirus pandemics, by optimizing our current vaccines, addressing variants of concern, developing next-generation COVID-19 vaccines, and initiating the development of broadly protective or universal coronavirus vaccines.
CEPI is an innovative partnership between public, private, philanthropic, and civil organizations, launched at Davos in 2017, to develop vaccines against future epidemics. Prior to COVID-19 CEPI’s work focused on developing vaccines against Ebola virus, Lassa virus, Middle East Respiratory Syndrome coronavirus, Nipah virus, Rift Valley Fever virus and Chikungunya virus – it has over 20 vaccine candidates against these pathogens in development. CEPI has also invested in new platform technologies for rapid vaccine development against unknown pathogens (Disease X).
During the current pandemic, CEPI initiated multiple programmes to develop vaccines against SARS-CoV-2 and its variants with a focus on speed, scale and access. These programmes leverage the rapid response platforms developed by CEPI’s partners prior to the emergence of COVID-19 as well as new collaborations. The aim is to advance clinical development of a diverse portfolio of safe and effective COVID-19 vaccine candidates and to enable fair allocation to these vaccines worldwide through COVAX.
CEPI’s 5-year plan lays out a $3.5 billion roadmap to compress vaccine development timelines to 100 days, develop a universal vaccine against COVID-19 and other Betacoronaviruses, and create a “library” of vaccine candidates for use against known and unknown pathogens. The plan is available at: http://www.endpandemics.cepi.net.
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. 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 virus neutralizing antibodies, broad T-cell immunity against SARS-CoV-2 variants and a strong booster memory recall inducing high levels of neutralizing antibodies against Delta, Omicron and other variants. UB-612 is now in a pivotal Phase 3 trial.
Vaxxinity, Inc. is a purpose-driven biotechnology company committed to democratizing healthcare across the globe. The company is pioneering a new class of synthetic, peptide-based immunotherapeutic vaccines aimed at disrupting the existing treatment paradigm for chronic disease, increasingly dominated by monoclonal antibodies, which suffer from prohibitive costs and cumbersome administration. The company’s proprietary technology platform has enabled the innovation of novel pipeline candidates designed to bring the efficiency of vaccines to the treatment of chronic diseases, including Alzheimer’s, Parkinson’s, migraine, and hypercholesterolemia. The technology is also implemented as part of a COVID-19 vaccine program. Vaxxinity has optimized its pipeline to achieve a potentially historic, global impact on human health.
