Outcomes of the 2nd International Conference on CRNs for Rare Diseases


In December 2025, the second International Conference on Clinical Research Networks (CRNs) for Rare Diseases was held in Heidelberg, Germany. Co-organised by the European Rare Diseases Research Alliance (ERDERA), Rare Diseases International (RDI) and the International Rare Diseases Research Consortium (IRDiRC), this event brought together members of the global rare disease community to explore innovative solutions for advancing clinical research, with a particular focus on strengthening capacity in low- and middle-income countries (LMICs).
The final report from the conference is now available online, providing key insights and reflections from organisers and speakers. The report also highlights the strategic objectives of the roadmap for strengthening global rare disease CRNs, and identifies a detailed roadmap of activities to implement by 2027:
- Publish a map of existing CRNs to identify complementarities and gaps, facilitating collaboration
- Agree on data harmonization and interoperability among CRNs
- Select diagnostic pilot sites to inform CRN clinical pathways
- Increase LMIC participation, such as through national patient hubs and country-level awareness campaigns
- Implement more inclusive, patient-led clinical trials in order to increase access to trials
- Develop sustainable, transparent multi-stakeholder governance
- Improve care pathways and quality of life for people living with a rare disease, drawing on existing models such as the Australian Rare Care Centre
- Expand diagnostic and interoperability pilots, launch international policy recommendations, and publish common KPIs for assessing diagnostic timelines, trial recruitment diversity and data quality
