Study of body fat in people with obstructive sleep apnea
This study looks at how body fat (“adipose tissue”) may differ in people with obstructive sleep apnea. You may be asked for consent and could be asked to stop certain medicines short-term so researchers can take a safe fat sample.
Rochester, MinnesotaAges 18–60 - NCT03372317Recruiting
Tau brain PET imaging study for adults ages 55–90
This study uses a brain scan called PET to look at tau (a brain protein) and how it relates to thinking and memory. It may help researchers understand early brain changes, though it’s mainly for healthy people living near Columbia who have had an amyloid PET scan before.
New York, New YorkAges 55–90 - NCT03314974RecruitingPhase 2
Stem cell transplant study for blood cancers
This Phase 2 study tests a strong (myeloablative) stem cell transplant using donor stem cells (allogeneic transplant) for certain blood and bone marrow cancers. The goal is to see how well this approach works and whether it can improve outcomes for people who need transplant-level treatment.
Minneapolis, MinnesotaAges Up to 60 years - NCT03368092RecruitingPhase 3
Inhaled medication to prevent lung failure after severe trauma
This trial tests whether inhaled dornase alfa can reduce the risk of respiratory (lung) failure in adults with severe trauma who are on a breathing machine in the ICU. If it works, it may help patients spend less time with dangerous breathing complications.
StrasbourgAges 18 years+ - NCT03067181RecruitingPhase 3
Active surveillance and chemotherapy for germ cell tumors
This study looks at how to manage germ cell tumors in children and young adults using careful monitoring for some patients and chemotherapy for others. It aims to see whether these approaches can control the cancer while avoiding unnecessary treatment when possible.
Birmingham, AlabamaAges Any age - NCT03254667Enrolling by invitation
Track outcomes in adults with moderate-to-severe psoriasis
This study keeps track of how people with moderate-to-severe psoriasis do over time while using Siliq or other approved treatments. It may help researchers understand how treatments compare in real life.
Bridgewater, New JerseyAges 18–99 - NCT03178149RecruitingPhase 1
Study of a new eye treatment for dry macular degeneration
This Phase 1 trial tests the safety and side effects of ASP7317 in older adults whose central vision is worsening from dry age-related macular degeneration (geographic atrophy). If you qualify, you would receive treatment in the study eye and be closely monitored for about a year.
Phoenix, ArizonaAges 50 years+ - NCT03028246Recruiting
Safety study using focused ultrasound for certain brain tumors
This study tests whether a focused ultrasound treatment is safe for children and young adults who have a non-cancerous (benign) tumor in the center of the brain. It mainly checks safety, and it also includes monitoring before and during treatment to reduce risks like bleeding or imaging-related problems.
Washington D.C., District of ColumbiaAges 5–22 - NCT03136146RecruitingPhase 2
Chemo for return or non-responsive blood cancers
This Phase 2 study tests a combination chemotherapy plan for certain leukemia and lymphoma types that have come back or did not respond. It may help shrink or control disease when standard treatment is no longer working.
Houston, TexasAges 15 years+ - NCT03035851Recruiting
Exercise program for older adults at risk of memory decline
This trial tests whether a structured aerobic (heart-pumping) exercise program can improve memory and thinking in older adults who feel memory trouble but have not been diagnosed with dementia. It focuses on people who are “at increased risk” due to common health factors like high blood pressure or diabetes.
Calgary, AlbertaAges 50–80 - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - NCT03150693RecruitingPhase 3
New treatment for young adults with CD22-positive ALL
This Phase 3 trial tests adding inotuzumab ozogamicin to standard chemotherapy for newly diagnosed CD22-positive B-cell acute lymphoblastic leukemia (ALL). It may help more patients achieve remission and reduce the risk of the leukemia coming back, while also checking safety and tolerability.
Birmingham, AlabamaAges 18–39 - NCT03067467Recruiting
MRI scan study of brain tumors using special carbon imaging
This trial uses a special MRI scan that shows how “metabolism” (how cells use fuel) differs in brain tumors. It may help researchers better understand tumor biology and how tumors may respond to treatment, without using chemotherapy or radiation as part of the study.
Dallas, TexasAges 18–70 - NCT03264352RecruitingPhase 4
Treatment for slightly high blood pressure in type 2 diabetes
This trial tests an intervention to help adults with type 2 diabetes who have “high-normal” blood pressure (not severely high). If you qualify, you may learn whether this approach improves blood pressure and related health outcomes over time.
Guangzhou, GuangdongAges 45–79 - NCT03117010Recruiting
Study of adults with suspected or confirmed HLH
This study follows adults who have findings that suggest HLH, a serious immune problem. It may help doctors better understand the condition by tracking patients over time and comparing symptoms and test results.
SeoulAges 18–80 - NCT03286335Recruiting
Proton radiation for slow-growing or benign brain tumors
This trial studies proton radiation therapy for adults with certain benign or slow-growing brain tumors. It aims to see how well tumors can be controlled, and how treatment affects quality of life and side effects.
Boston, MassachusettsAges 18 years+ - NCT03274050Recruiting
Testing robotic surgery for children and adults needing operations
This trial studies how well and how efficiently robotic surgery works in both children and adults who need a procedure where robotic surgery is appropriate. It may help surgeons plan safer, smoother operations and improve operating-room efficiency.
Paris, ParisAges Any age - NCT02703220RecruitingPhase 4
Sleep apnea treatment in older adults
This study tests whether certain medications can help older adults with mild to moderate sleep apnea breathe better during sleep. It aims to improve sleep quality and safety for elderly patients.
Detroit, MichiganAges 60–89 - NCT02682667Recruiting
Providing blood samples for cancer immunotherapy research
This study collects and stores blood/tissue samples (called biospecimens) to support immunotherapy research at the cancer center. If you may qualify, your samples help researchers test new immune-based cancer treatments.
Bethesda, MarylandAges 18–120 - NCT02830308Recruiting
Adult study evaluating endocrine and metabolic health
This trial enrolls adults with known or suspected hormone (endocrine) or metabolism-related conditions for clinical evaluation. The goal is to help doctors assess and better understand what’s causing these health problems.
Bethesda, MarylandAges 18–100 - NCT02701153Recruiting
Short pre-surgery radiation for soft-tissue sarcoma
This trial tests a short course of radiation before surgery to shrink a soft-tissue sarcoma and make it easier to remove. It may help by improving how well the tumor can be removed, while studying safety and effectiveness for this cancer type.
