Readout from Legacy Ultimovacs DOVACC Phase II Trial Concludes UV1 Programme as Previously Guided

Oslo, 26 June 2026 – Zelluna (OSE: ZLNA) , a company pioneering allogeneic "off-the-shelf" T Cell Receptor-based Natural Killer (TCR-NK) cell therapies for the treatment of solid cancers, today announces that the NSGO-CTU sponsored Phase II DOVACC clinical trial (NCT04742075) investigating the Ultimovacs UV1 cancer vaccine, inherited through the business combination between the two companies in 2025, did not meet the primary endpoint. This concludes the previously communicated wrap-up phase of the UV1 cancer vaccine programme and Zelluna now considers the programme closed.
