ExpreS2ion Biotech

The data indicate that the antigens identified through Evaxion’s AI-Immunology™ platform and produced using ExpreS2ion’s ExpreS2™ technology successfully trigger targeted immune responses, including activation of CMV reactive B and T cells. To further enhance efficacy, Evaxion designed a prefusion gB antigen, a proven CMV vaccine component shown to offer partial protection in human trials leveraging ExpreS2ion’s platform. Preclinical data confirm that this proprietary gB antigen induces specific immune responses, similar to traditional gB antigens. The companies plan to emphasize this prefusion gB antigen in a multi-antigen vaccine approach to enhance CMV protection.

Farshad Guirakhoo, Chief Science Officer, commented

“Despite decades of research, CMV vaccines remain challenging. We’re encouraged by preclinical data showing that our ExpreS2-produced prefusion gB, designed using Evaxion’s AI, generates strong immune responses in mice. This novel antigen will likely be a key component of our upcoming multi-antigen vaccine candidate for clinical trials.”

About cytomegalovirus (CMV)

According to the National Library of Medicine (August 2023), 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, as well as the development of new and effective treatments. CMV is the most complex of all herpes viruses, and it 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.
