Systemic-onset juvenile idiopathic arthritis

This study tests a new oral medication, upadacitinib, in children aged 1 to 17 with active systemic juvenile idiopathic arthritis (sJIA), a rare and serious form of arthritis that can affect the whole body. About 90 participants will receive either upadacitinib or the standard in…

This study is testing the long-term safety and effectiveness of the drug filgotinib in children and adolescents aged 8 to 17 with juvenile idiopathic arthritis. Participants must have already completed a previous filgotinib study and shown improvement. The goal is to see if the d…

This study tests a new medicine called MAS825 for people with Still's disease, a rare inflammatory condition causing fever, rash, and joint pain. About 20 children and adults with active disease will receive the drug to see if it safely controls symptoms. The goal is to improve d…

This study looks at how patients with Familial Mediterranean Fever (FMF) and Still's disease (including systemic juvenile idiopathic arthritis and adult-onset Still's disease) use the drug canakinumab (Ilaris) over the long term. Researchers will track 160 patients across Europe …

This study is for children and teens aged 1 to 17 with systemic juvenile idiopathic arthritis (sJIA), a condition that causes joint swelling and fever. Researchers are testing different doses of the drug sarilumab to find the best amount that works and is safe. The study involves…

This study watches children and adults who are already taking or about to start Ilaris for hereditary periodic fever syndromes or systemic juvenile idiopathic arthritis. Researchers will track side effects and how well the drug controls symptoms over 16 weeks. No new medicine is …

This study is testing a less intense chemotherapy and radiation regimen before a stem cell transplant for children and young adults up to age 55 with non-cancerous blood disorders like immune deficiencies, anemias, and metabolic diseases. The goal is to see if this gentler prepar…

This study compares two types of hip replacement materials in 100 adults aged 18 to 65 who need a total hip replacement. One group gets a ceramic-on-polyethylene implant where the polyethylene is infused with vitamin E to reduce wear. The other group gets a standard ceramic-on-ce…

This study tests whether sleeping near a special device that claims to emit 'biophotons' can reduce chronic severe arthritis pain. About 102 adults with long-term arthritis pain will use either the active device or a placebo (inactive) device for 12 weeks. Researchers will measur…

This study tests two ways to manage pain after hip replacement surgery. One group gets a nerve block plus a second nerve block; the other gets a nerve block plus wound numbing. The goal is to see which method reduces pain and the need for opioid painkillers. About 102 adults havi…

This study tests whether eating freeze-dried wild blueberry powder every day for 12 weeks can improve gut health, reduce inflammation, and ease joint pain in adults with arthritis. Fifty participants will take either the blueberry powder or a placebo, with a 2-week break between …

This study aims to learn more about the genetics and natural history of autoinflammatory diseases, which cause repeated fevers and inflammation. Researchers will study up to 5,000 people, including patients, their relatives, and healthy volunteers. Participants provide blood and …

This study will analyze DNA from up to 20,000 people, including those with immune disorders and their relatives, to find genetic variants linked to conditions like atopy, autoimmunity, and primary immunodeficiency. Researchers will also study how best to return genetic results to…

This study aims to understand the causes and progression of systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD) by observing up to 2,000 participants over time. Researchers will collect medical history, blood samples, and genetic data to identify …

This study will follow 200 people who have had a complex or revision hip replacement at University Hospitals Leuven. The goal is to track how many need another surgery and why, and to improve care by learning from real-world results. No new treatment is being tested—this is an ob…

This study aims to better understand VEXAS syndrome and other autoinflammatory conditions by analyzing participants' DNA from blood, saliva, or skin samples. Researchers hope to discover new genetic variants that cause or contribute to these diseases. The study enrolls people of …

This study looks at whether sulfasalazine, a drug for inflammatory arthritis, makes the standard diabetes blood test (HbA1c) falsely low. That could mean diabetes goes undiagnosed or is undertreated in these patients. Researchers will use continuous glucose monitors and fasting b…

This study aims to learn how well heart scans (MRI, ultrasound, PET) can detect and predict outcomes in people with suspected or known inflammatory heart diseases. Researchers will follow 5,000 adults for one year to see how often heart involvement is confirmed and how it affects…

This study is looking at 50 children and adults with rare autoinflammatory diseases—conditions where the immune system causes inflammation without a clear reason. Researchers want to find what leads to a faster diagnosis, what factors are linked to these diseases, and which treat…

This study is creating a large collection of joint fluid and blood samples from 500 people with different types of arthritis. Researchers will use these samples to test new biomarkers that could help diagnose arthritis earlier and monitor how the disease changes over time or with…

This study is for people with certain autoinflammatory diseases (like NOMID, DIRA, CANDLE, SAVI, and others) and their healthy relatives. Researchers want to learn more about what causes these diseases and how they affect the body over time. Participants will have medical tests a…

This study aims to create a large collection of blood samples and medical information from 800 people with autoimmune or inflammatory skin diseases. Researchers will use these samples to find new biomarkers and better understand what causes these conditions. The goal is to help d…

This study is looking for new genes and biological markers that cause systemic autoinflammatory diseases (SAIDs), a group of rare conditions that cause repeated fevers and inflammation. Researchers will analyze the DNA and blood of 300 patients to find disease-causing mutations a…

This study will follow 500 adults and children with Still disease, a rare inflammatory condition causing fever, joint pain, and rash. Researchers aim to compare how the disease affects different age groups, identify early markers, and improve care. No new treatments are being tes…

This study looks at how often people can return to sports at least three years after total knee replacement. It compares three different types of knee prostheses to see if one type leads to better sports participation. The study will include 660 adults who had their first knee re…

This study looks at people with autoinflammatory diseases or AA amyloidosis who have genetic changes that are hard to interpret. Researchers want to understand if these changes actually cause the disease. The goal is to improve diagnosis and knowledge, not to test a new treatment…
