Boston, MassachusettsAges 1 day+ - NCT03052283Recruiting
Abdominal symptom score test for people with cystic fibrosis
This trial helps create and check a patient-friendly questionnaire that measures abdominal (belly) involvement in cystic fibrosis. It may help your care team better track symptoms over time.
Brandenburg an der HavelAges Any age - NCT03128996RecruitingPhase 1/Phase 2
Bone marrow transplant with lighter chemo for non-cancer illnesses
This early-phase study tests a safer “lighter” conditioning chemo plan before a bone marrow transplant for people with non-cancer blood and immune disorders. It aims to reduce transplant risk while using donor marrow that does not match perfectly in the HLA type.
New Haven, ConnecticutAges 1 day–21 years - NCT03308916Recruiting
Screening for liver scarring risk using noninvasive tests
This study checks people who are at higher risk for liver scarring by using noninvasive tests. If those tests suggest significant scarring, the study may consider further testing, but not everyone will need a biopsy.
OdenseAges 30–75 - NCT03326921RecruitingPhase 1
T cell treatment for leukemia after a bone marrow transplant
This early-phase trial tests an immune “T cell” therapy made to recognize a specific leukemia target. It is for people whose acute leukemia has come back (relapsed) or did not fully respond after receiving a donor stem cell transplant.
Seattle, WashingtonAges Up to 80 years - NCT03425526RecruitingPhase 1
Donor T-cell treatment for adenovirus illness in immune-weakened people
This early-phase study tests donor immune cells (T cells) to treat people who have adenovirus infection or adenovirus-related disease but have a weakened immune system. It may help your body fight the virus, especially in cases where other treatments may not be enough.
Houston, TexasAges Any age - NCT03617237Recruiting
Radiation patient registry for cancer and non-cancer cases
This study keeps records to understand outcomes for people who had radiation treatment (or were evaluated for it) since 2000. It may help doctors compare results for different conditions and treatment approaches, including cancer and non-cancer problems.
Dallas, TexasAges 18–99 - NCT03773159Recruiting
Testing a blood clot test using whole blood flow
This trial tests a new lab device that measures how well your body forms primary blood clots while blood is kept in flowing conditions. It may help doctors better assess bleeding or clotting tendencies and guide future care.
BesançonAges 18 years+ - NCT03803553RecruitingPhase 3
Testing blood tumor DNA treatment after stage III colon surgery
This trial studies how to find tiny hidden cancer cells after stage III colon cancer surgery using a blood test. If the blood test shows tumor DNA, you may get additional treatment to lower the chance of cancer coming back.
Boston, MassachusettsAges 18 years+ - NCT03835767RecruitingPhase 2
Predicting food allergy from blood IgE levels in eczema patients
This study looks for blood test patterns that may predict whether a child with eczema (atopic dermatitis) is likely to have a food allergy. If you join, you may do supervised oral food challenges with a placebo and the suspected foods to see what triggers symptoms.
Bethesda, MarylandAges 3–21 - NCT03865914Recruiting
Study linking diabetes kidney findings to biopsy results
This study looks at people with type 2 diabetes who have kidney problems and relates their symptoms and lab findings to what is seen on kidney biopsy. It may help doctors better understand what is driving kidney damage in diabetes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04049591Recruiting
Higher vs lower heparin dose during planned heart stent procedure
This trial compares a higher versus lower dose of heparin (a blood thinner) during a planned PCI, which is a heart procedure to open blocked arteries using a stent. It may help hospitals and patients know which dosing approach is safest and works well during the procedure.
Hamilton, OntarioAges 18 years+ - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Duarte, CaliforniaAges 18–75 - NCT04187729Recruiting
Precision Genomics Biobank for People Seen in Clinic
This study builds a large DNA and health information “biobank” from adults who visit Intermountain Health. It may help researchers understand how genes relate to health and disease by comparing “healthy” people with people who have medical conditions.
Murray, UtahAges 18 years+ - NCT04229056Recruiting
Computer training to improve thinking and planning after stroke or Parkinson’s
This trial tests computer-based “self-training” to improve executive function, such as working memory—your ability to hold and use information in mind. It’s for adults with a prior stroke, cardiac arrest, or Parkinson’s disease who have trouble on a specific working-memory task.
CopenhagenAges 18–100 - NCT04286308Recruiting
Testing brain-speech recordings during DBS for movement disorders
This study looks at how brain and speech networks work while people with Parkinson’s disease, essential tremor, or dystonia are getting deep brain stimulation (DBS). It may help doctors better understand and possibly improve speech outcomes for people receiving DBS.
Boston, MassachusettsAges 18–85 - NCT04397484RecruitingPhase 4
Compare two local anesthetics after foot nerve blocks
This study tests whether lidocaine or levobupivacaine works better for how a nerve block behaves after foot surgery. It may help doctors choose the anesthetic that provides more reliable pain control after surgery.
Shatin, New TerritoriesAges 18–75 - NCT04441151Recruiting
Pulmonary rehab for adults on high-flow oxygen therapy
This trial tests whether pulmonary rehabilitation (supervised breathing and activity training) improves outcomes for adults who need high-flow oxygen. You may be eligible if your breathing and heart/vital signs are stable and your oxygen level is above a certain threshold.
Beijing, Beijing MunicipalityAges 18–100 - NCT04444128Recruiting
Testing heart risk assessment using MRI T1 mapping
This study checks whether an MRI heart scan measure called “T1 mapping” can improve how doctors estimate heart disease risk in everyday people. You may join if you’re an adult and can have a contrast-enhanced heart MRI safely.
Frankfurt am Main, HesseAges 18 years+ - NCT04505865Recruiting
Mindfulness program to reduce inflammation in heart disease
This trial studies whether a mindfulness (stress-reducing) program can lower “vascular inflammation” (inflammation in blood vessel walls) in people with stable coronary disease. It may help by improving stress and related inflammation markers while you stay on your usual heart medicines.
Boston, MassachusettsAges 45–65 - NCT04521790Recruiting
Biopsy-guided treatment for suspected inflammation of the heart
This study looks at people 18 and older with suspected myocarditis (inflammation of the heart). It uses an inner-heart biopsy and tailored treatment based on the likely cause to improve diagnosis and care, especially for people with different heart rhythm or non-rhythm symptoms.
