Evaxion宣布新数据探索使用人工智能设计的个性化癌症疫苗EVX-01治疗后的免疫反应

Evaxion A/S (NASDAQ:EVAX) ("Evaxion"), a clinical-stage TechBio company specializing in developing AI-Immunology™ powered vaccines, announces new data exploring immune responses following treatment with AI-designed personalized cancer vaccine EVX-01. The data was presented today in a poster session at the Society for Immunotherapy of Cancer (SITC) 2025 Annual Meeting taking place in National Harbor, Maryland.

Developed with Evaxion's AI-Immunology™ platform, EVX-01 is designed to target multiple neoantigens - cancer unique proteins arising from mutations - and to induce a clinically relevant immune response. The new biomarker and immune data stems from the phase 2 trial evaluating EVX-01 in combination with MSD's (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) in patients with advanced melanoma (skin cancer).

Longitudinal patient blood samples were collected before, during and after treatment to unravel treatment-induced changes in specific immune cell populations. More specifically, circulating T-cell subsets were characterized aiming at increasing the understanding of the immune responses induced by EVX-01. In subsets of analyzed patients, clinical responses were accompanied by a rapid and sustained induction of EVX-01-specific T-cells.

"We are pleased with the opportunity to present these exploratory translational data at a conference as important as SITC as we continue to add to EVX-01's strong data package. Having presented the two-year clinical efficacy data from the phase 2 trial just last month at the European Society for Medical Oncology 2025 congress, we are encouraged by the interest in EVX-01 from the medical community", says Birgitte Rønø, CSO and interim CEO of Evaxion.
