European Rare Diseases Research Alliance (ERDERA) Joint Transnational Call 2026

With an estimated overall budget of 380 million euros until 2031, ERDERA aims to have a major impact on rare diseases by supporting patient driven research to develop new treatments and diagnostic pathways and harnessing the potential of health and research data, Artificial Intelligence (AI) and digital technologies.

The European Union contributes around 150 million euros to this co-funded partnership via Horizon Europe, while the rest of the funding comes from member states, countries associated to Horizon Europe and in cash and in-kind contributions from public and private partners.

Built on the solid foundations laid by the European Joint Programme on Rare Diseases (EJP RD), ERDERA brings the community, the data and the resources together to accelerate prevention, diagnosis and treatment.
