New biomarker and immune data from the ongoing phase 2 trial with EVX-01 will be presented at the American Association for Cancer Research (AACR) Annual Meeting These data will further add to the already strong clinical data package for EVX-01The trial remains on track for two-year clinical efficacy data readout in the second half of 2025

COPENHAGEN, Denmark, March 25, 2025 - Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company specializing in developing AI-Immunology™ powered vaccines, will present new data for its lead asset EVX-01 at a poster session at the American Association for Cancer Research (AACR) Annual Meeting taking place in Chicago April 25-30, 2025. Designed with Evaxion’s AI-Immunology™ platform, EVX-01 is a personalized cancer vaccine currently being evaluated as a treatment for advanced melanoma (skin cancer).

Evaxion will present new biomarker and immune data obtained from the ongoing phase 2 trial. These will further add to EVX-01’s already strong clinical data package.

“We are proud to be selected by the AACR’s scientific committee to present new data at this very renowned and important scientific meeting. This is a testament of the high scientific value of the EVX-01 clinical program, and we are excited to get the chance to present and discuss the data with a big audience in the field of melanoma research”, says Birgitte Rønø, Chief Scientific Officer of Evaxion.
