• New preclinical data demonstrates that CMV antigens identified with Evaxion’s AI-Immunology™ platform trigger targeted immune responses
• Results also showcase the successful design of a proprietary prefusion glycoprotein B (gB) antigen with ability to neutralize the virus
• Evaxion is advancing these new findings to develop a multi-component CMV vaccine candidate
• About 1 in 200 babies is born with congenital CMV infection and the virus infects approximately 60% to 70% of adults in developed countries. No approved CMV vaccine exists today

COPENHAGEN, Denmark, November 12, 2024 - Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company specializing in developing AI-Immunology™ powered vaccines, announces new positive preclinical data from its ongoing cytomegalovirus (CMV) vaccine program named EVX-V1. The data will be presented today at the 9th International Conference on Vaccines Research & Development, taking place in Boston, USA.

The data demonstrates that the antigens identified with Evaxion’s AI-Immunology™ platform effectively trigger targeted immune responses, including induction of both CMV reactive B and T cells. To further enhance vaccine effectiveness, Evaxion has additionally designed a proprietary prefusion gB antigen, a well-established CMV vaccine component known to offer partial virus neutralization. New preclinical data confirms that Evaxion’s proprietary gB antigen successfully induced a specific immune response comparable to that of the conventional gB antigen.

Based on these findings, we expect to combine AI-Immunology™ identified CMV vaccine antigens with our proprietary prefusion gB antigen in a future vaccine candidate. This novel multi-target approach stands out from traditional methods focusing on a limited set of glycoproteins involved in viral entry. Combatting the virus from numerous angles is expected to enhance the efficacy of our future vaccine.

The new data has been generated in collaboration with Expres2ion Biotechnologies as part of the research collaboration initiated in December 2022. The antigens identified through Evaxion’s AI-Immunology™ platform have been produced using ExpreS2ion’s ExpreS2™ technology.

“We are pleased with these positive outcomes of the initial preclinical studies in our CMV vaccine program, demonstrating our AI-Immunology™ platform’s ability to identify novel antigens to combat viral diseases. These encouraging data bring us one step closer to developing an effective CMV vaccine. Our AI-Immunology™ platform enables a novel and broader approach to tackling CMV, and we look forward to presenting the findings at the conference and engaging in discussions with virology experts,” says Birgitte Rønø, CSO of Evaxion.

About cytomegalovirus (CMV)

About 1 in 200 babies is born with congenital CMV infection. About 1 in 5 babies with the infection will have congenital disabilities or other long-term health problems. CMV infects approximately 60% to 70% of adults in developed countries and nearly 100% in developing economies, driving demand for CMV treatment. Despite decades of research, no CMV vaccine has been approved to date.

CMV treatment market size was valued at $474.6 million in 2023 and is anticipated to register an annual growth (CAGR) of 6.6% between 2024 and 2032. This growth is propelled by increasing awareness and prevalence of CMV infection and the development of new and effective treatments.

CMV is the most complex of all herpes viruses and is a widespread infection transmitted in body fluids. Once infected, the virus stays for life. People with weakened immune systems, including organ transplant patients, can develop severe symptoms affecting, for example, eyes, lungs, and liver, and congenitally infected babies may suffer from intellectual disability and loss of vision and hearing.
