EVX-03

Data from three separate clinical trials documents the strong ability of the AI-Immunology™ platform to select clinically relevant vaccine targets Strongest outcomes are generated by the top-ranked AI-Immunology™ vaccine targets, thereby linking AI-vaccine design with real-world evidence This underscores the platform’s unique potential in selecting effective vaccine targetsThe ongoing generation of relevant clinical data allows for continuous refinement of AI-Immunology™ thereby broadening the commercial potential of the platform COPENHAGEN, Denmark, October 9, 2024 – Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company specializing in developing AI-Immunology™ powered vaccines, has now evidence from three different clinical trials validating the vaccine target predictions of its AI platform. Evaxion has developed three personalized cancer vaccine candidates with the use of its AI-Immunology™ platform. Two of these – EVX-01 and EVX-02 – have completed clinical phase 1 testing and EVX-01 is currently in phase 2, while the third – EVX-03 – is an IND-ready vaccine candidate. The AI-Immunology™ platform identifies cancer vaccine targets, so called neoantigens, and assigns a prediction score reflecting the likelihood of each vaccine target to elicit a specific immune response against the tumor. In all three clinical trials, a statistically significant correlation was observed between the AI-Immunology™ prediction scores and the immunological responses measured in the patients, with the most robust responses being generated by vaccine targets with the highest AI-Immunology™ prediction scores. Further, in the one trial where it was assessed, a statistically significant correlation was demonstrated between AI-Immunology™ prediction scores and Progression Free Survival (PFS) in patients, underscoring the platform's ability to identify vaccine targets with meaningful clinical impact. “We are proud to have collected such strong clinical data documenting the unique predictive capabilities of the AI-Immunology™ platform across several clinical trials. The correlation between the platform’s prediction score and clinical outcome is unique and provides very solid guidance for the further development of personalized cancer vaccines based upon AI-Immunology™. Generating highly relevant clinical data is very important for our ability to apply constant learning loops, allowing for the continuous development of AI-Immunology™,” says Christian Kanstrup, CEO of Evaxion.

Promising clinical data from Phase 1 and 2a studies with EVX-01 and EVX-02 were presented at AACR and ASCO in Q2 2023A novel proprietary genetic vaccine adjuvant was presented at Evaxion’s R&D Day in May. The technology is an integral part of the next-generation cancer vaccine, EVX-03, planned for phase 1 clinical trial application in Q4 2023*Promising results on EVX-B1, a Staphylococcus aureus vaccine candidate, were presented at the Staphylococcal Diseases Gordon Research Conference in New Hampshire, USA, in Q2 2023.Financial agreement secured with Global Growth Holding Limited (GGHL) totaling up to USD 20 millionCash and cash equivalents of $7.1 million at June 30, 2023 sufficient to fund operations into December 2023 *Subject to additional funding in the range of $5-10 million secured before initiation COPENHAGEN, Denmark, Aug. 18, 2023 (GLOBE NEWSWIRE) -- Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion” or the “Company”), a clinical-stage biotechnology company specializing in the development of AI-driven immunotherapies, today provided a business update and announced its second quarter 2023 financial results. “At Evaxion, we believe that AI-powered, personalized cancer vaccines have the potential to transform the care of patients with melanoma and other cancers. Early-stage clinical data reported at AACR 2023 and ASCO23 indicated that patients treated with our vaccines, EVX-01 or EVX-02, in combination with a checkpoint inhibitor, experienced a treatment benefit, with good overall tolerability” said Per Norlén, Chief Executive Officer of Evaxion. “These data support the potential clinical utility for personalized cancer immunotherapy and the opportunity to advance our next-generation, DNA-based candidate, EVX-03, towards clinical trials in cancer patients.” “Additionally, at a time of positive industry data and renewed interest in personalized cancer vaccines, Evaxion is making excellent scientific progress. Utilization of two new, proprietary technologies, including the AI platform ObsERV™, which enables identification of novel cancer antigens called ERVs, which are patient-specific cancer targets of viral origin, plus our novel genetic adjuvant, are believed to further enhance the efficacy of EVX-03,” said Per, concluding, “On a separate note, we were pleased to present preclinical proof-of-concept data at the Gordon Conference showing that EVX-B1 can clear staphylococcus infections. Taken together, these clinical advances and proof-of-concept milestones highlight the potential for Evaxion’s AI-powered technology to address unmet medical needs in oncology and infectious diseases. The recent completion of an up to $20 million USD financing will support progression of our current studies and operations, while initiation of EVX-03 phase 1 activities are subject to additional funding." Anticipated milestones Q4 2023 - Interim results of EVX-01 Phase 2 trial in melanomaQ4 2023 – Clinical trial application for EVX-03* *Subject to additional funding in the range of $5-10 million secured before initiation Recent Milestones (April to August 2023)Completion of financing commitments totaling up to USD 20 million Evaxion announced completion of a financing commitment totaling up to $20 million with Global Growth Holding Limited, available in tranches over the next three years.

Promising preclinical data presented at the Staphylococcal Diseases Gordon Research Conference Preclinical data showed EVX-B1, a vaccine against Staphylococcus aureus (S. aureus) containing AI-identified antigens, is highly protective against S. aureus disease in pre-clinical models and that EVX-B1 effectively clears S. aureus infections. Promising early clinical data presented for EVX-01 and EVX-02 EVX-01 presentation at ASCO23. Phase 1 results showed positive clinical responses in 8 out of 12 patients receiving EVX-01 in combination with a checkpoint inhibitor. The trial also met primary endpoints for tolerability and safety, with only mild AEs being related to EVX-01.EVX-02 presentation at AACR 2023. Phase 1/2a results showed that all 10 patients with late stage melanoma who completed EVX-02 treatment demonstrated robust and treatment-specific immune responses and were relapse-free at their last assessment. R&D Day Highlights Preclinical Data on genetic adjuvant technology R&D Day 2023. In a series of talks from its scientists and collaborators, Evaxion provided an introduction to its proprietary genetic adjuvant technology developed to enhance the effectiveness of DNA and mRNA vaccines. The genetic adjuvant can be encoded into either DNA or mRNA vaccines to boost the immune response. Preclinical data show that the technology boosts both B cell and T cell immune responses, making it applicable to a wide range of vaccines, both for cancer and for infectious disease.
