Study of how craniofacial differences develop over time
This study follows children and adults with craniofacial (head/face) differences to learn how their growth changes over time. It also enrolls unaffected family members and healthy volunteers to compare what is “typical,” using scans and optional genetic testing.
Bethesda, MarylandAges 2–100 - NCT02417740Recruiting
Study of the natural course of noncirrhotic portal hypertension
This study follows people with noncirrhotic portal hypertension (NCPH) or people at risk for it to better understand how the condition progresses over time. It does not sound like a medication trial—more like careful monitoring to learn what happens in different people.
Bethesda, MarylandAges 12–100 - NCT02302742Recruiting
Registry for triple-negative breast cancer and inherited mutation carriers
This registry studies people with triple-negative breast cancer or inherited “HBOC” gene mutations (like BRCA, PALB2, PTEN, TP53). It collects information to better understand risk, outcomes, and how these cancers behave—helping future research and care.
Hays, KansasAges Any age - NCT02315521Recruiting
Pregnancy care study for babies with LUTO
This study tests a standardized plan of prenatal (during pregnancy) care for pregnancies where the baby has LUTO, regardless of when the diagnosis was made. It may help families by testing whether consistent prenatal monitoring and management improves outcomes for babies with this condition.
Houston, TexasAges 3 months–2 years - NCT02346435Recruiting
Watch small kidney growths, with added follow-up later
This registry follows people who have a small kidney mass found by chance on recent scans. It helps doctors understand the best timing for monitoring and possible treatment, to improve safety and outcomes.
Baltimore, MarylandAges 18–100 - NCT02391519Recruiting
Study how high altitude affects body energy signaling
This study compares how the body responds to high altitude around the time of a planned C-section, including a signal involved in energy use. It may help researchers understand why pregnancy and blood-vessel function can differ at higher elevations.
Aurora, ColoradoAges 18–45 - NCT02382601Recruiting
Study of pregnancies with slow fetal growth
This study follows pregnancies where the baby appears smaller than expected on ultrasound. It may help researchers better understand why this happens and how to monitor care over time.
Aurora, ColoradoAges 18–45 - NCT02491099RecruitingPhase 2
Afatinib for recurring HER2-positive uterine cancer
This trial tests afatinib, a targeted pill, in people whose uterine serous cancer has a specific HER2 (HER2/neu) tumor marker. It aims to shrink tumors or control the cancer when it keeps coming back.
Tucson, ArizonaAges 18–100 - NCT02601339Recruiting
NIRS monitoring in premature babies with brain fluid problems
This study uses a special light-based monitor (NIRS) to track blood flow in the brain of premature infants. It compares babies in different conditions related to bleeding, fluid buildup, or other brain fluid changes to help doctors understand what monitoring can show.
Boston, MassachusettsAges birth–1 year - NCT02193542Recruiting
Study of breathing tube and epidural difficulty in childbirth
This study observes how often pregnant people have a difficult airway (trouble placing a breathing tube) or difficult neuraxial placement (like an epidural) during childbirth. It helps doctors improve safe delivery care.
Boston, MassachusettsAges Any age - NCT02411773RecruitingPhase 1
Test a nerve-blocking medicine in kidney disease
This Phase 1 study tests whether a medicine that reduces nerve signals (“sympatholysis”) is safe and how it affects people with chronic kidney disease. It may help researchers understand new ways to protect the kidneys, but the main goal here is safety.
Decatur, GeorgiaAges 18–75 - NCT02321007Recruiting
Study placenta function in healthy and pregnancy complications
This study examines how the placenta works in normal pregnancies and in pregnancies with certain complications. Your answers and pregnancy information may help researchers understand why complications like growth problems or preterm birth happen.
Aurora, ColoradoAges 18–45 - NCT02497521Recruiting
Registry for adults with ADPKD starting tolvaptan
This registry study collects information about adults with autosomal dominant polycystic kidney disease (ADPKD) who are starting or already taking tolvaptan. It may help researchers understand how tolvaptan is used in real life and what outcomes look like over time.
Müllheim, Baden-WurttembergAges 18 years+ - NCT02496104Recruiting
Study brain “habituation” in preterm and full-term babies
This study looks at how babies’ brains get used to repeated sights or sounds (habituation) in both preterm and full-term infants. It may help researchers understand early brain development differences and improve care for newborns.
BrestAges 2 days–2 months - NCT02333604Recruiting
Cancer experience registry for patients and caregivers
This registry collects information about the experiences of people with cancer and the people who care for them. Joining could help researchers better understand needs and improve support, without requiring cancer treatment changes.
Washington D.C., District of ColumbiaAges 18 years+ - NCT02578810Recruiting
Testing blood pressure drug signals in pregnancy with severe preeclampsia
This trial studies how certain blood markers and brain-wave signals change in pregnant people with severe preeclampsia, especially when it leads to eclampsia (seizures). The goal is to better understand warning signs and treatment response to keep mother and baby safer.
Kuala LumpurAges 18–50 - NCT02609269Enrolling by invitation
Study using your Decipher genetic test results
This study uses the Decipher genetic test results you already had to help researchers learn how to improve cancer care. You may be included simply because you previously completed that specific test.
Ages Any age - NCT02235857Recruiting
Device treatment study for children with focal segmental kidney scarring
This trial studies a medical device (the Liposorber LA-15) in children with focal segmental glomerulosclerosis (FSGS), a kidney condition that can cause heavy protein loss in the urine. It may help by improving disease control when standard treatments have not worked, were hard to tolerate, or can’t be used.
Loma Linda, CaliforniaAges Up to 21 years - NCT01950572Recruiting
Biopsy study to learn about mesothelioma and related cancers
This study collects tissue samples (biopsies) and health information to better understand malignant mesothelioma and certain related solid tumors that may produce a protein called mesothelin. It may help future research and treatments, and you can only join if your diagnosis is confirmed and it’s safe for you to have the tissue taken.
