Farmington, ConnecticutAges 18 years+ - NCT04365855Recruiting
Study of fatty liver risk in local adults
This study looks at how common fatty liver disease is and what factors may be linked to it in adults in Olmsted County. You may be asked about health history, alcohol use, and possibly to undergo MRI scans.
Rochester, MinnesotaAges 18 years+ - NCT04375631RecruitingPhase 1
Study of chemo plus donor stem cell transplant for blood cancers
This Phase 1 trial tests a specific chemotherapy plan followed by a reduced-intensity donor stem cell transplant for people with relapsed or treatment-resistant acute myeloid leukemia (AML), certain myelodysplastic syndromes (MDS), or chronic myelomonocytic leukemia (CMML). It may help by using donor stem cells to rebuild the bone marrow after intensive cancer treatment, in people who are not responding well to standard therapies.
Seattle, WashingtonAges 18 years+ - NCT04374799RecruitingPhase 3
Heparin vs placebo during cardiac catheterization
This trial tests whether giving heparin (a blood thinner) during a specific type of heart procedure is safer and works better than not giving it. It focuses on patients where the blood supply in the hand’s artery connection is functioning properly.
Hamilton, OntarioAges 18 years+ - NCT04307615Recruiting
Oxygen versus CPAP during emergency lung fluid episodes
This trial tests whether regular oxygen or CPAP (a breathing-support machine) works better for people who have swimming-induced pulmonary edema, a sudden buildup of fluid in the lungs after swimming. It may help doctors choose the safest and most effective breathing treatment in an emergency.
FalunAges 18 years+ - NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Phoenix, ArizonaAges birth–20 years - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT04372875Recruiting
Help for teens using health tech in the emergency room
This trial tests whether using a health information technology tool in the emergency department can improve sexual health care and reduce health disparities for teens. It focuses on gathering survey and screening information so care can better meet needs.
Washington D.C., District of ColumbiaAges 15–21 - NCT04343365Recruiting
