Amniotic stem cell treatment for calciphylaxis
This early-phase study tests a stem cell therapy made from amniotic (placenta) tissue for people with calciphylaxis. If you qualify, the goal is to see whether this treatment is safe and potentially helpful for this rare, painful condition.
Nanjing, JiangsuAges 18–75 - NCT04599621Recruiting
Testing treatment for heart pain with anxiety or depression
This trial looks at people who have coronary artery disease and unstable or certain stable chest-pain symptoms, especially when anxiety or depressive symptoms are also present. The goal is to see how the study approach helps heart symptoms when mental health symptoms occur at the same time.
SamarkandAges Any age - NCT04601363Recruiting
Personalized spine registry for people with spinal hardware
This registry follows people who recently had spinal surgery where custom (patient-specific) spine hardware (like rods) was placed. It collects consent and health questionnaires to learn how these implants affect patients over time.
Aurora, ColoradoAges 10–85 - NCT04602325Recruiting
Blood and brain injury biomarker study for inherited metabolic disorders
This trial studies blood and other measurable signs (biomarkers) that may reflect brain injury after certain inherited metabolic conditions. Results may help doctors better detect and understand brain effects from these illnesses, especially episodes that affect the brain.
Washington D.C., District of ColumbiaAges 7–18 - NCT04604782RecruitingPhase 1/Phase 2
Regadenoson study in children to test safety and dosing
This trial tests how safe regadenoson is in children and how the body handles it after dosing. It also uses a heart “stress test” with MRI (CMR) when doctors feel it’s needed.
ParisAges 4 weeks–18 years - NCT04606459Recruiting
Device trial for hard-to-treat heart chest pain from small vessels
This trial tests whether a small pressure-reducing device placed in a heart vein (the coronary sinus) can reduce symptoms in people with ongoing chest pain from tiny blood vessel problems. It is for angina that has not improved despite standard heart medicines, and only if special heart tests show reversible reduced blood flow.
Mainz, Rhineland-PalatinateAges 18–85 - NCT04606732Recruiting
Tracking heart risk changes after COVID-19 hospitalization
This study looks at how COVID-19 affects heart health over time in people who were hospitalized. Your results may help doctors predict prognosis and understand who is at higher heart risk after recovery.
BolognaAges 18 years+ - NCT04607174Recruiting
Test knee muscle activation in people with nerve or movement disorders
This study checks how well your knee muscles “turn on” during guided, controlled knee movements. It may help researchers understand movement problems and improve testing or therapies for neuromotor (nerve/movement) disorders.
Milan, MIAges 18–70 - NCT04612322Recruiting
Study registry for microvascular angina patients
This registry study collects information from adults with microvascular angina (chest pain from small blood vessels in the heart). It may help researchers better understand how to assess and manage this condition over time.
Mainz, RLPAges 18–85 - NCT04613921Recruiting
Liver transplant study for severe worsening liver failure
This study looks at when liver transplant is offered and what outcomes happen in people with cirrhosis who have severe “acute-on-chronic” worsening. It may help doctors decide which patients benefit most from transplant and improve care after listing or not listing.
Los Angeles, CaliforniaAges 18–80 - NCT04615065Recruiting
Biobank study collecting emergency data for very sick patients
This study collects health and sometimes blood sample information from people arriving at the emergency department with high-risk or serious conditions. The goal is to build a large emergency “biobank” to help researchers better understand and improve urgent care.
