Ravulizumab Outcomes in Polish Patients with aHUS
This observational study in Poland follows patients with atypical hemolytic uremic syndrome who are treated with ravulizumab to see how they do over time in real-world clinical care.
-
Ravulizumab for people with clinical aHUS
This study will test whether ravulizumab raises platelet counts in people diagnosed with clinical atypical hemolytic uremic syndrome (aHUS), including those with certain infections (excluding pneumococcal and STEC), pregnancy/postpartum, recent kidney transplant, malignant hypertension, or autoimmune conditions.
-
National Registry for Rare Kidney Diseases
This study is collecting health information from people with rare kidney diseases to help improve treatments and create better care guidelines.
-
Using RNA sequencing to diagnose rare genetic diseases
This study is testing if a new RNA sequencing method can help find the genetic causes of rare diseases in people who haven't been diagnosed after other tests.
-
Switching from anti-C5 antibody treatment to iptacopan for aHUS patients
This study is testing if switching to a new treatment called iptacopan can help people with atypical hemolytic uremic syndrome (aHUS) feel better after using a different medication.
-
Understanding rare gene mutations in atypical hemolytic uremic syndrome for personalized therapy
This study is testing how rare gene mutations in people with atypical hemolytic uremic syndrome can help doctors create personalized treatments to improve their health.
-
Long-term evaluation of iptacopan for patients with atypical hemolytic uremic syndrome
This study is testing how well the medication iptacopan works and how safe it is for people with atypical hemolytic uremic syndrome over a longer period of time.
-
Registry for patients with rare diseases
This study is creating a central registry for people with rare diseases to help connect them with researchers and improve treatments.
-
Registry for patients with Atypical Hemolytic-Uremic Syndrome
This study is collecting information from people with Atypical Hemolytic-Uremic Syndrome to see how the disease progresses in those treated with eculizumab or ravulizumab and those who aren't treated at all.
