About us

We are a Health Research Board (HRB) – funded network aiming to increase activity in rare disease clinical trials in Ireland. Through collaboration with patients, researchers and industry, we support development of rare disease clinical trials, trial methodology and researcher training, while keeping the patient voice at the centre of everything we do.

Why join the Rare Disease Clinical Trial Network?

International Expertise

The network is a collaboration hub that links with international expertise and advocacy groups to exchange ideas, build capacity, foster partnerships and speed up innovation in rare disease research.

Patient Led

Our public and patient involvement (PPI) activities ensure that the patient voice is at the heart of everything we do. This leads to better quality research and outcomes that meet the needs of the rare disease community.

Greater Access to Clinical Trials

Our international collaborations, PPI activities and support for industry & researchers help to increase the quantity and quality of rare disease clinical trials in Ireland.
