Recent clinical data confirms significantly improved predictive power of Evaxion's AI-Immunology™ platform

• Improved precision of the AI-Immunology™ platform in predicting clinically relevant vaccine targets boosts the potential of its AI-derived vaccine candidates
• The improvement has been achieved through iterative learning and the integration of advanced bioinformatics and machine learning techniques
• In the ongoing phase 2 trial with personalized cancer vaccine EVX-01, 79% of the AI-Immunology™ predicted vaccine targets triggered a tumor-specific immune response, a significant increase from 58% observed in the EVX-01 phase 1 trial
• The precision level seen with AI-Immunology™ in predicting targets triggering the desired immune response is very encouraging compared to other approaches
• The ability to select vaccine targets eliciting a tumor-specific immune response is pivotal for a vaccine’s clinical efficacy and resulting commercial potential
  
  

COPENHAGEN, Denmark, October 3, 2024 – Evaxion Biotech A/S (NASDAQ: EVAX) ("Evaxion”), a clinical-stage TechBio company specializing in developing AI-Immunology™ powered vaccines, continues to gather clinical evidence for the steady improvement of its AI-Immunology™ platform.

The platform’s precision has significantly improved between the two clinical trials with Evaxion’s personalized cancer vaccine EVX-01. In the ongoing phase 2 trial, 81 out of 103 (79%) vaccine targets assessed to date triggered a tumor-specific immune response, a notable increase from the 58% observed in the phase 1 trial completed last year.

The high number of immune-active vaccine targets is observed across all patients. The ability to trigger a broad and consistent tumor-specific immune response is pivotal for a vaccine’s clinical efficacy and, thereby, critical for the vaccine’s commercial potential and ability to address unmet medical needs.

"As a truly AI-first TechBio company, Evaxion rests on our leading AI-Immunology™ platform and its continued improvement remains a top priority for us. It is, of course, very pleasing to see that we are successful in that work, reaching 79% of identified vaccine targets triggering an immune response in the ongoing EVX-01 phase 2 trial. This compares very favorably to data reported from other personalized cancer neoantigen trials. We are further pleased that the clinical outcome data are also very strong, providing us with a compelling AI-Immunology™ derived investigational vaccine candidate.” says Christian Kanstrup, CEO of Evaxion.

The improvement of the AI-Immunology™ platform's predictive capabilities results from iterative learning loops, optimization based on clinical data and the integration of novel bioinformatic and machine learning methodologies.
