Rhea-AI Filing Summary

Evaxion A/S reports a strategic refocus of its oncology R&D pipeline by introducing EVX-05, an AI-designed, off-the-shelf therapeutic vaccine program targeting glioblastoma, while discontinuing the EVX-03 program as part of portfolio management. EVX-05 uses the company’s AI-Immunology™ platform to identify conserved endogenous retrovirus (ERV)-derived antigens shared across glioblastoma patients.

Evaxion is collaborating with Duke University School of Medicine, where Professor Mustafa Khasraw’s team is expected to conduct initial clinical testing, potentially in a cost-efficient phase 1 trial. Management states that EVX-05 development costs fit within existing budgets and that the company’s cash runway continues into the second half of 2027. A conference call on August 20, 2026 will cover Q2 2026 results and the new program.

Positive

  • Cash runway maintained into second half of 2027 despite adding EVX-05, as management states the program’s costs are covered by existing budgets, supporting ongoing development without shortening the funding horizon.
  • New EVX-05 glioblastoma vaccine program launched with a collaboration at Duke University School of Medicine, providing access to world-leading clinical expertise and a potentially cost-efficient path to initial clinical testing.

Negative

  • EVX-03 program discontinued and removed from Evaxion’s R&D pipeline as part of portfolio management, reducing the number of active cancer vaccine programs in development.

AI-Immunology™ technical
"developing novel vaccines with its pioneering AI-Immunology™ platform"
ai-immunology™ is the use of artificial intelligence techniques to analyze immune system data and guide the discovery, design and testing of immune-based diagnostics, vaccines and therapies. It matters to investors because it can speed up research, reduce costs and reveal promising drug targets that traditional methods might miss—like using a powerful search engine to find a few needles in a vast haystack of biological signals—potentially increasing the chance and pace of commercial returns.

FAQ

What did Evaxion A/S (EVAX) announce about its R&D pipeline on this 6-K?

Evaxion announced a refocus of its R&D pipeline, launching EVX-05, an AI-designed off-the-shelf glioblastoma vaccine program, and discontinuing the EVX-03 program as part of portfolio management while keeping its stated cash runway unchanged.

What is EVX-05 in Evaxion A/S (EVAX)’s new program?

EVX-05 is described as an off-the-shelf therapeutic glioblastoma vaccine. It targets conserved endogenous retrovirus (ERV)-derived antigens identified using Evaxion’s AI-Immunology™ platform, aiming to offer a novel immunotherapy approach in a cancer with high mortality and limited treatment options.

Evaxion is collaborating with Duke University School of Medicine on EVX-05. Professor Mustafa Khasraw and his team are expected to conduct initial clinical testing, providing world-leading clinical expertise and a potentially cost-efficient way to run a phase 1 trial.

What is the medical need Evaxion A/S (EVAX) targets with EVX-05?

EVX-05 targets glioblastoma, described as the most aggressive malignant primary brain tumor. The company cites an incidence of 3.19 per 100,000 people in the U.S., a median age of 64 years, and about 50% of patients dying roughly one year after diagnosis.

EXHIBIT 99.1

Evaxion expands and refocuses R&D pipeline with EVX-05, an AI-designed off-the-shelf brain cancer vaccine program

  • EVX-05 is an off-the-shelf therapeutic glioblastoma (brain cancer) vaccine designed based on patient tumor samples. It targets novel conserved antigens identified using Evaxion’s AI-Immunology™ platform
  • Glioblastoma is characterized by high mortality rates and significant unmet medical needs. EVX-05 is being developed as a novel therapeutic approach to treat glioblastoma
  • Evaxion is collaborating with a world-leading academic medical research institution, which is expected to conduct initial clinical testing of EVX-05
  • Evaxion maintains its cash runway into second half of 2027 as its R&D pipeline is refocused with the addition of EVX-05 while the EVX-03 program is discontinued

COPENHAGEN, Denmark, August 17, 2026 - Evaxion A/S (NASDAQ: EVAX) (“Evaxion”), a clinical-stage TechBio company developing novel vaccines with its pioneering AI-Immunology™ platform, expands it pipeline of cancer vaccine programs with EVX-05 against the deadly brain cancer glioblastoma.

We are collaborating with experts from Duke University School of Medicine to develop EVX-05. This program targets endogenous retrovirus (ERV)-derived antigens shared between glioblastoma patients, which AI-Immunology™ has unique capabilities in identifying. These ERV-antigens constitute a novel source of highly attractive targets for off-the-shelf cancer vaccines.

With its new therapeutic concept, EVX-05 is being developed as a novel therapeutic approach for glioblastoma. Current therapies are often inadequate, meaning glioblastoma remains one of the most aggressive and deadly cancers.

“We are delighted to transform our discoveries in glioblastoma into a promising new vaccine program with EVX-05, which could hold a significant therapeutic potential in area of massive unmet medical need. We have an outstanding collaboration with Duke University and now see the huge benefits of combining their extensive disease understanding and clinical expertise with the unique target discovery capabilities of AI-Immunology™,” says Birgitte Rønø, CSO and COO of Evaxion.

"Patients with glioblastoma continue to face limited treatment options and poor outcomes,” said Mustafa Khasraw, M.D., professor at Duke University School of Medicine. “The potential of ERVs as therapeutic targets has long been acknowledged, if we can unlock this potential, it would be a significant advancement towards improving care.”

World-leading expertise
Evaxion is currently undertaking optimization of a lead vaccine candidate for the EVX-05 program as part of advancing it towards initial clinical testing. This is expected to be carried out by Professor Khasraw and his team, allowing for world-leading clinical expertise and knowledge of patient needs to help guide clinical development. The collaboration also potentially allows a cost-efficient way for Evaxion to study EVX-05 in a clinical phase 1 trial.

EVX-05 builds on the same ground-breaking ERV-targeting concept as EVX-04, Evaxion’s vaccine candidate against acute myeloid leukemia. This confirms the broad applicability of the concept across cancers where immunotherapies remain inadequate and conserved immunogenic antigens can be identified.

Both programs draw on learnings from the EVX-03 program, which has now been discontinued and removed from our R&D pipeline as a matter of portfolio management. The costs related to EVX-05 are captured within Evaxion’s existing budgets and hence does not impact on our cash runway, which continues to stretch into second half of 2027.

Conference call and webcast
This coming Thursday, August 20, Evaxion’s Executive Management will host a conference call and webcast at 8.30 ET/14.30 CET today, presenting our Q2 2026 business update and financial results as well as taking questions. EVX-05 will be one of the topics discussed.

About glioblastoma
Glioblastoma is the most aggressive malignant primary brain tumor. It has an incidence rate of 3.19 per 100,000 persons in the United States and a median age of 64 years (National Institute of Health).

No cure exists for glioblastoma, and treatment outcomes remain poor: 50% of patients die approximately one year from diagnosis (New England Journal of Medicine, 2005).
