aHUS Alliance Action is dedicated to supporting patients with atypical Hemolytic Uremic Syndrome (aHUS), particularly by improving their access to vital information on treatment trials. The organization has formed a significant partnership with ClinicalTrials.eu. This collaboration aims to benefit aHUS patients, especially in Europe, by providing a search engine on ClinicalTrials.eu with up-to-date information on relevant clinical trials available in seven languages, including dedicated pages for aHUS.
