Using brain-related “seeds” to help diagnose Alzheimer’s disease
This study looks for specific markers (“seeds”) that may help doctors diagnose Alzheimer’s disease and distinguish it from other memory or thinking conditions. If you are in the right age range and can complete memory testing and provide a sample, you may help validate a diagnostic approach.

Congenital heart disease transplant registry study for adults
This study collects and shares anonymous information about adults being considered for a heart transplant because of a congenital (from birth) heart problem or an inherited heart muscle condition. The goal is to better understand these patients and support research that may improve care.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT04799470Recruiting
Testing new brain-stimulation patterns for Parkinson’s with DBS
This study tests whether different deep brain stimulation settings can improve symptoms in people with Parkinson’s who already have an implanted DBS system in the subthalamic nucleus (STN). To join, you must already have the specific Medtronic device and show good brain signal and symptom response after surgery.
Omaha, NebraskaAges 19–80 - NCT04806347RecruitingPhase 1
Stem cell transplant using a half-matched donor for children and young adults
This trial studies a type of stem cell transplant (bone marrow transplant) that uses a donor who is only half-matched to the patient, often a parent or sibling. It is for children and young adults with certain blood diseases, including sickle cell disease, thalassemia, bone marrow failure, and immune disorders. The transplant aims to replace the diseased blood-forming cells with healthy ones from the donor.
Madison, WisconsinAges 3 months–25 years - NCT04848740Enrolling by invitation
Tested implant for worsening thin corneas
This trial looks at whether placing a donor-like cornea “lenticule” implant can help people whose cornea is getting worse, becoming thin, and causing blurry or reduced vision. The goal is to see if the implant can improve corneal clarity and vision in progressive disease.
PristinaAges 20–60 - NCT04833907Enrolling by invitationPhase 1/Phase 2
Gene therapy study for typical Canavan disease in children
This early-phase trial tests a gene therapy medicine (delivered by a one-time infusion) for children with typical Canavan disease. It aims to improve safety and help evaluate whether the treatment may benefit children over time.
Dayton, OhioAges 3 months–5 years - NCT04819841RecruitingPhase 1/Phase 2
Gene correction using your own stem cells to improve sickle disease
This trial tests a gene-correction treatment that changes sickle hemoglobin (HbS) into normal hemoglobin (HbA) using your own stem cells. It may help reduce severe sickle cell complications for people with severe disease who meet specific safety and medical criteria.
Los Angeles, CaliforniaAges 12–50 - NCT03671889Recruiting
Ultrasound treatment to open the brain barrier for Alzheimer’s
This trial tests a non-surgical ultrasound procedure (called MR-guided focused ultrasound) meant to temporarily “open” the brain’s protective barrier so treatments may work better for Alzheimer’s disease. It also looks at safety and how well people tolerate the procedure and related tests.
Delray Beach, FloridaAges 50–85 - NCT04697966Recruiting
Smartphone mindfulness program for teens and what predicts improvement
This study tests an app-based mindfulness training program for adolescents ages 13–18 and looks at what helps predict which teens improve. It may be helpful if you’re looking for a structured mindfulness practice and want to understand what changes in your thinking and feelings over time.
Belmont, MassachusettsAges 13–18 - 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+ - NCT04770584Recruiting
Fear and avoidance study in PTSD and healthy volunteers
This study looks at how people with current PTSD—or people without PTSD—respond to fear and avoiding things they might find threatening. It may help researchers understand these patterns and how they differ after trauma.
Houston, TexasAges 18–70 - 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+ - NCT04698421Recruiting
Blood and tissue sample collection for rare autoimmune nerve diseases
This study collects biological samples (like blood or other specimens) from people with rare neurological conditions that may involve the immune system. Your samples may help researchers better understand these diseases.
ToulouseAges 6–99 - NCT04698291Recruiting
Study how genetic differences affect calming immune signals
This study looks at how genetic changes may affect special “calming” immune molecules that help the body resolve inflammation. You may be invited if you already joined the Genes & Health project and had your genome analyzed, and you meet safety and health criteria.
LondonAges 18 years+ - NCT04753970RecruitingPhase 1/Phase 2
Study uses retina changes to assess blood vessel health
This study looks at the back of your eyes (the retina) to see if it reflects blood vessel health in the brain. It may help doctors find easier ways to track conditions related to small blood vessel disease.
Jacksonville, FloridaAges 18 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 - NCT04726241RecruitingPhase 1/Phase 2
Testing blood and bone marrow samples in young leukemia patients
This trial looks at blood and bone marrow samples from children and teens whose leukemia has come back or is hard to treat. The goal is to better understand the disease and guide future options for these patients.
Birmingham, AlabamaAges Up to 22 years - NCT04744116RecruitingEarly Phase 1
Cord blood cell therapy added to ruxolitinib for steroid-resistant GVHD
This trial studies whether adding cord-blood–derived cells to ruxolitinib can improve steroid-resistant acute graft-versus-host disease (GVHD) affecting the lower gut or liver. It’s meant for people who are not getting better (or are worsening) despite adequate steroid treatment.
Houston, TexasAges 12–80 - 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+ - NCT04731857Recruiting
Genetic testing results study for rare diseases
This study looks at how well different genetic tests (whole exome/genome sequencing and standard genetic tests) work for diagnosing rare genetic diseases and inherited cancer conditions. It may help confirm which testing approach provides the clearest results for families.
TübingenAges Any age - 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.
