Evaxion and Pantherna announce promising preclinical mRNA vaccine data

COPENHAGEN, Denmark and HENNIGSDORF, Germany, Feb. 08, 2023 (GLOBE NEWSWIRE) -- Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion” or the “Company”), a clinical-stage biotechnology company specializing in the development of AI-powered immunotherapies and Pantherna Therapeutics GmbH (“Pantherna”), a biopharmaceutical company developing advanced nanoparticle solutions for the delivery and expression of mRNA therapeutics, today announced preclinical proof of concept for the combination of the two companies’ key technologies.

The preclinical data demonstrate that tumor neoantigens identified by Evaxion’s AI platform, PIONEER, drive a strong immune response and lead to complete inhibition of tumor growth in a preclinical model when delivered using Pantherna’s proprietary lipid nanoparticle mRNA platform (PTXΔLNP^®, PTXmRNA^®).

“We are extremely pleased with the preclinical data that clearly demonstrate the potential for our combined technologies. The data provide further evidence that immunogenic sequences identified by Evaxion’s AI platforms are able to drive a relevant immune response on multiple vaccine platforms, including mRNA. This opens up many opportunities in our current and future immuno-oncology and infectious disease programs,” says Birgitte Rønø, CSO at Evaxion.

“We are encouraged by the data and see an enormous potential of combining Evaxion’s AI-based antigen discovery engines with our state-of-the-art mRNA-LNP platforms. The preclinical data substantiate the relevance of enhancing the efficiency of mRNA actions in the body and validates the ability of our platform to induce an immune response,” says Klaus Giese, CEO at Pantherna.

In continuation of these positive findings, Evaxion and Pantherna will further explore optimal LNP formulations to effectively deliver mRNA and DNA-encoded antigens identified by Evaxion’s AI platforms.
