Edmonton, AlbertaAges Any age - NCT04707781Recruiting
Database study for people at risk of lung scarring
This trial is a study database that collects information from adults who have other illnesses that can increase the risk of developing interstitial lung disease (lung scarring). It may help researchers better understand who is at risk and how outcomes change over time.
GrazAges 18 years+ - NCT04710576RecruitingPhase 2
Axatilimab for chronic graft-versus-host disease
This trial tests a new drug called axatilimab to help patients whose chronic graft-versus-host disease (a condition where transplanted immune cells attack the body) isn't responding well to standard treatments. Researchers want to find the right dose and see if it can improve symptoms and quality of life.
Birmingham, AlabamaAges 2 years+ - NCT04708587Recruiting
Choosing the right anti-platelet duration for advanced kidney disease
This study looks at the best length of anti-platelet medicine (which helps prevent stent clots) after a new type of heart stent. It specifically focuses on people with advanced chronic kidney disease, where bleeding and clot risks can be higher.
SeoulAges 19–84 - NCT04709900Recruiting
Tests for stable chest pain using heart scans and pressure measurements
This trial studies how well different heart tests (imaging the blood flow and measuring blood pressure in the heart) work for people with stable chest pain. It may help guide safer, more accurate evaluation when you are not having a heart attack.
CopenhagenAges Any age - NCT04715568RecruitingPhase 4
Testing how smoke exposure affects heart health
This study looks at whether being exposed to secondhand tobacco smoke at work affects heart and blood vessel health. It may help researchers understand which people are at higher risk and how the body responds to that exposure.
San Francisco, CaliforniaAges 40 years+ - NCT04715984Recruiting
Testing brain-circuit targets during DBS surgery in Parkinson’s
This study looks at how brain connections involved in movement may relate to thinking and memory problems in Parkinson’s disease. It happens during a deep brain stimulation (DBS) operation, using tests while the surgeon is placing an electrode.
Nashville, TennesseeAges 40 years+ - NCT04720560Recruiting
Study how immune cells affect fatty liver disease
This study looks at how certain immune cells (“regulatory B cells”) may contribute to metabolic fatty liver disease. You might be able to join if you’re an adult with fatty liver but not pregnant and not on certain treatments.
AsyutAges 18–80 - NCT04724941Recruiting
Screening for alpha-synuclein in early Parkinson’s risk
This study looks for changes in a protein called alpha-synuclein in people who may be in the early “prodromal” stage before Parkinson’s symptoms fully appear. It may help researchers find early markers and understand who is more likely to develop Parkinson’s disease.
KielAges 50–99 - NCT04731246Recruiting
Eye-movement testing in people with early Parkinson’s
This study uses video recordings of your eye movements to learn more about Parkinson’s disease. It may help researchers better tell Parkinson’s apart from other movement conditions and understand how the disease affects the brain early on.
MonacoAges 18 years+ - NCT04735627Recruiting
Real-time monitoring of levodopa levels in Parkinson’s
This study checks whether measuring levodopa (a Parkinson medicine) in real time can help better understand Parkinson medication effects. You may be asked to wear/perform study monitoring while taking your usual carbidopa/levodopa tablets.
San Diego, CaliforniaAges 40–85 - NCT04740541Recruiting
Diet study for adult men with Crohn’s disease
This study looks at how a specific amino-acid (threonine) diet affects adults with Crohn’s disease and signs of intestinal inflammation. It may help researchers understand what dietary protein needs could support more stable disease.
Toronto, OntarioAges 18–49 - NCT04740580RecruitingEarly Phase 1
Test glutathione for brain inflammation in Alzheimer’s
This early-stage study tests whether taking glutathione can affect brain “inflammation” and metabolism in people with Alzheimer’s disease. You might benefit from a new treatment approach, while helping researchers understand what works best for early Alzheimer’s-related brain changes.
Houston, TexasAges 55–85 - NCT04741646RecruitingPhase 2
Ferric citrate for kids with chronic kidney disease
This Phase 2 study tests ferric citrate, a medicine that helps control phosphate and iron balance, in children with chronic kidney disease. It may help slow problems related to kidney disease by improving lab measures like phosphate levels.
