Full Press Release Details
COPENHAGEN, Denmark, November 20, 2025 - Evaxion A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company specializing in developing AI-Immunology™ powered vaccines, is successfully advancing its novel multi-component cytomegalovirus (CMV) vaccine program, EVX-V1, with new data demonstrating protective effects of lead antigens in the program.
With our AI-Immunology™ platform, we have uncovered novel antigens that are entirely new to the CMV vaccine research field. These previously unexplored CMV-antigens induce specific immune responses, inhibit viral infection and reduce cell-to-cell spread in cellular and animal viral infection models. These are significant discoveries since very few protective CMV-antigens have been identified despite decades of intensive research.
The new findings add to earlier data demonstrating that Evaxion’s proprietary AI-optimized pre-fusion glycoprotein B (gB) antigen effectively neutralizes CMV. This enhanced gB antigen constitutes a key component of EVX-V1, which combines AI-discovered antigens with AI-optimized conventional antigens to attack the virus from multiple, complementary angles. This broader multi-targeted strategy is expected to strengthen the protective potential of the future vaccine.
“We are very excited by the new data demonstrating the unique capability of AI-Immunology™ to find novel protective vaccine targets where no others have been able to do so. This further exemplifies how our technology enables the discovery of potentially groundbreaking new therapies and offers hope for improved prevention of CMV infections, an area of significant medical need”, says Birgitte Rønø, CSO and interim CEO of Evaxion.
Evaxion continues the preclinical advancement of the EVX-V1 program with further identification, investigation and optimization of antigens. In parallel, Evaxion is actively exploring strategic partnerships to accelerate development and ensure a seamless transition into non-clinical and clinical phases.
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.
