French biotechnology firm ErVimmune has successfully closed the first tranche of its Series A financing, securing $19.8 million to advance its lead cancer vaccine candidate into clinical trials. This pivotal funding coincides with the appointment of seasoned biotech executive Eric Halioua as the new Executive Chairman of its board. The combined developments signal a significant step forward for the company's mission to treat cancers that are unresponsive to current immunotherapies.


A New Frontier in Cancer Immunotherapy

ErVimmune's lead candidate, ErVac01, is a next-generation therapeutic vaccine targeting novel tumor antigens derived from Human Endogenous Retroviruses (HERVs). These viral remnants in the human genome are expressed in cancer cells, making them ideal targets for the immune system. The vaccine is designed as an "off-the-shelf" product, avoiding the complexities and costs associated with personalized therapies.

The primary focus is on "cold" tumors, such as triple-negative breast cancer and ovarian cancer, which have notoriously poor responses to existing checkpoint inhibitors. By utilizing a collection of HERV-derived epitopes, ErVac01 is engineered to be effective across a broad global population. The upcoming first-in-human clinical trial will be a crucial step in establishing the vaccine's safety and immunogenicity.

Securing Strategic Investment

The $19.8 million financing was supported by an international syndicate of investors, demonstrating strong confidence in ErVimmune's innovative approach. The round included participation from existing shareholder Seventure Partners and was joined by new investor SPRIM Global Investments. This capital will also enable the company to access additional non-dilutive funding from Bpifrance and the France 2030 program.

Investors have expressed enthusiasm for the company's direction, with Seventure Partners highlighting the technology as a new frontier in cancer immunotherapy. SPRIM Global Investments noted that the financing marks an inflection point in validating ErVimmune’s antigen discovery platform. Both see the clinical advancement of ErVac01 as a decisive step toward creating a new era of shared cancer immunotherapies.

Bolstering Governance with Industry Expertise

To guide its transition into a clinical-stage company, ErVimmune has appointed Eric Halioua as Executive Chairman of the board. Halioua brings a wealth of experience in strategic leadership, capital raising, and corporate development within the biotechnology sector. His appointment is timed to strengthen governance and provide expert oversight as the company navigates its next critical phase of growth.

Halioua's distinguished career includes founding four biotech companies and serving as CEO of PDC*line Pharma and Promethera Biosciences. He has successfully raised over $199 million from global venture capital firms and has been instrumental in several M&A transactions and IPOs. Halioua stated he looks forward to supporting the team in clinical execution and building a leading immuno-oncology company.


With a substantial Series A funding round secured and a highly experienced executive at its helm, ErVimmune is strongly positioned to advance its pioneering cancer vaccine platform. The upcoming clinical trial for ErVac01 represents a critical milestone in the quest to transform treatment paradigms for patients with aggressive, hard-to-treat cancers. The company's progress will be closely watched as it aims to translate its innovative science into tangible benefits for patients worldwide.
