• The clinical trial of the customized cancer vaccine EVX-01 met its main endpoints of security and tolerability
• Constructive clinical responses had been reported in eight out of 12 EVX-01 treated individuals
• Higher-high-quality neoantigens, predicted by AI technologies, had been related with longer progression-absolutely free survival
• Powerful vaccine-particular immune responses had been induced in all 12 EVX-01 treated patients 
• Larger EVX-01 dose induced a stronger immune response and was related with enhanced clinical outcome

COPENHAGEN, Denmark, June 03, 2023 (GLOBE NEWSWIRE) — Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion” or the “Company”), a clinical-stage biotechnology organization specializing in the improvement of AI-powered immunotherapies, now presented promising clinical information from its EVX-01 Phase 1 dose escalation trial in metastatic melanoma at the 2023 ASCO annual meeting in Chicago, Illinois. 

The Phase 1 trial effectively met main endpoints for security and tolerability of EVX-01 in metastatic melanoma individuals and demonstrated good clinical responses in eight out of 12 (67%) treated individuals. In addition, Evaxion’s proprietary AI technologies PIONEER™ was in a position to determine higher-high-quality cancer vaccine targets, so-named neoantigens, related with longer progression-absolutely free survival.

“We are excited that our AI technologies could successfully determine vaccine neoantigens related with much better clinical responses and longer progression-absolutely free survival. And the information recommend a therapy impact, with response prices practically double of these observed in historical information for checkpoint inhibitors. Our findings in this study position us properly to prospectively determine individuals who will advantage from customized cancer immunotherapy for our upcoming trials, potentially generating the advantage for individuals even higher,” mentioned Per Norlén, Chief Executive Officer of Evaxion. 

The study demonstrated the capacity of the PIONEER™ platform to determine vaccine targets that are related with enhanced patient outcomes. Stratification primarily based on PIONEER™ scores outperformed tumor mutational burden as a predictive biomarker, with individuals obtaining higher-high-quality neoantigens displaying much better therapy responses and longer progression-absolutely free survival. 

The evaluation of therapy-connected immune responses revealed strong neoantigen T-cell responses in all 12 individuals, mediated by activated CD4+ T cells in all instances and CD8+ T cells in 7 out of 12 individuals. Additional, immune response magnitude correlated with the vaccination dose.  

“The good association among clinical outcome and prevalence of immunogenic cancer neoantigens validates the PIONEER™ platform for its use for customized cancer vaccines and emphasizes the significance of a robust AI technique for designing neoantigen vaccines. In addition, the dose-dependent raise in responses has been instrumental for Phase two dose choice in the ongoing clinical trial. We have fantastic expectations on the upcoming interim Phase two benefits that are planned to be presented later this year,” Per Norlén continues. 

About the Phase 1 Study with EVX-01 
The open-label, single-arm, single-center Phase 1 study, titled “Personalized Neo-antigen Vaccine in Sophisticated Strong Tumors (NeoPepVac)” (ClinicalTrials.gov Identifier: NCT03715985), was performed in collaboration with DTU, SSI, the center for genomic medicine at Rigshospitalet and CCIT-DK and aimed to assess the security and efficacy of EVX-01 vaccine in mixture with anti-PD1 (pembrolizumab or Nivolumab) in individuals with metastatic melanoma. The style consisted of a number of 15-27mer peptides comprising one particular or additional patient-particular neoantigens formulated with the novel liposomal adjuvant CAF®09b to potentiate immune responses. The main objective was to decide the security and tolerability of the mixture of EVX-01 and a checkpoint inhibitor. Added objectives had been to evaluate manufacturing feasibility, immune responses, and clinical efficacy.
