The new data demonstrates EVX-04’s complete expression in human cells, including correct transcription and translation. Further, EVX-04 is secreted in human cells, enabling immune recognition and activation.

The data also shows that all ERV antigens included in EVX-04 drive specific immune responses both in mice (in vivo) and human cells (in vitro) across different human immune profiles. These vaccine-induced immune cells mediate targeted cell-killing, highlighting EVX-04’s potential as a new effective therapeutic cancer vaccine.

Data will be presented at a poster presentation at the European Hematology Association (EHA) 2026 Congress taking place in Stockholm, Sweden, on June 13, 2026.

“We are excited to share the new data on EVX-04, which could potentially greatly improve treatment options for AML patients. We are successfully executing the preclinical activities and in parallel preparing the regulatory filing for clinical testing and are looking forward to discussing the data and the program at the EHA congress,” says Birgitte Rønø, CSO & COO of Evaxion.
