Bethesda, MarylandAges 18–100 - NCT00977977RecruitingPhase 2
Rituximab plus cyclosporine for membranous kidney disease
This trial tests whether rituximab (an immune-targeting medicine) plus cyclosporine (another immune medicine) can better control protein leakage in the urine for people with idiopathic membranous nephropathy. It may help reduce long-lasting kidney damage risk when standard treatments like ACE inhibitor or ARB don’t control the protein level.
Bethesda, MarylandAges 18–90 - NCT00668187Recruiting
Study of the natural history of gangliosidosis
This study follows people with gangliosidosis to better understand how the condition changes over time. You may be asked to complete thinking/behavior tests and, if you have late-onset disease, get a head MRI (a painless scan) to help researchers track changes in the brain.
Minneapolis, MinnesotaAges Any age - NCT00794352Recruiting
Studying immune brain and nerve conditions with tests and samples
This study looks at how immune-related brain or spinal cord illness shows up using exams, MRI scans, and sometimes a spinal fluid test (lumbar puncture), plus collected blood and other samples. It may help researchers better understand these conditions and improve future diagnosis or treatments.
Bethesda, MarylandAges 1 month–99 years - NCT01631617RecruitingPhase 2
Atopic dermatitis treatments and how they affect skin
This Phase 2 study tests different treatments for atopic dermatitis (eczema) by looking at changes in skin health. It may help people find safer, more effective ways to control moderate to severe eczema and related skin infections.
Bethesda, MarylandAges 2–50 - NCT02530983Recruiting
Survey study for people after esophagus surgery
This study is a survey. It asks people about their experiences after esophagus surgery (either removing part of the esophagus or rebuilding it). It may help doctors understand what happens to patients over time and improve future care.
Rochester, MinnesotaAges 18 years+ - NCT02817997Recruiting
Registry for people with Castleman disease worldwide
This trial is a worldwide registry that collects basic medical information from people diagnosed with Castleman disease. It helps researchers learn about real-world care and outcomes across different ages and care settings.
Philadelphia, PennsylvaniaAges Any age - NCT02543996Recruiting
Providing blood or tissue samples to study disease
This study collects and stores biological samples (like blood and cord blood) to help researchers understand what causes disease. You may be asked to provide samples during pregnancy, delivery, or from an affected person, depending on eligibility.
Bethesda, MarylandAges 1 month–100 years - NCT02504879Recruiting
Study of melorheostosis progression and genetic causes
This study follows adults with suspected or confirmed melorheostosis to understand how the condition develops and what outcomes to expect. It may help researchers better understand the disease and its genetic factors.
Bethesda, MarylandAges 18–90 - NCT02649985RecruitingPhase 1/Phase 2
PET brain scan study for several brain and mood conditions
This early-phase study uses PET and MRI brain scans to better understand brain changes in multiple sclerosis, Alzheimer’s disease, and other neurological or mood conditions. The goal is to test whether these scans can show disease-related differences and guide future treatments.
Boston, MassachusettsAges 18–85 - NCT02769975Recruiting
Check children and teens with hormone and metabolism problems
