T-cell therapy for stubborn Epstein-Barr virus after transplants
This trial tests an immune therapy made from EBV-targeted T-cells to treat EBV infections that do not improve with standard anti-viral medicines. It may help by strengthening the body’s ability to fight EBV after certain transplants or immune problems.

Testing tumors linked to viruses, HIV, and immune disorders
This study collects and analyzes tumor tissue to learn what drives certain cancers and growths linked to viruses, HIV, and immune system problems. Results may help researchers understand disease causes and point to better future treatments.
Bethesda, MarylandAges 18 years+ - NCT03299608Recruiting
Breath test to quickly detect infections in blood cancer patients
This study tests whether a quick breath test can detect infections early in people receiving intensive treatment for certain blood cancers or bone marrow transplant patients. If it works, it could help doctors find infections faster and adjust treatment sooner.
LeuvenAges 18 years+ - NCT03325855Recruiting
Fecal transplant registry for patients and donors
This study is a national “registry” that collects information from people who get fecal microbiota transplant (a stool-based treatment) and from people who donate stool. It helps researchers understand who receives these treatments and how they do over time.
Phoenix, ArizonaAges Any age - NCT03334006RecruitingPhase 2
Tested special immune-targeting treatment after abdominal infection surgery
This Phase 2 study tests whether Pentaglobin®, a blood-product made from immune proteins, helps critically ill people with severe abdominal infection (peritonitis) after the infection source is surgically cleaned up. It targets patients with signs of strong inflammation and severe illness.
ViennaAges 18 years+ - NCT03337932Recruiting
Shorter doxycycline course for multiple early Lyme skin rashes
This study looks at how long to take doxycycline for people who have multiple early Lyme disease skin rashes. It may help find the shortest effective treatment duration while keeping side effects low.
LjubljanaAges 18 years+ - NCT03365609Recruiting
Testing different treatment plans for H. pylori in children
This study compares four ways to treat H. pylori (a stomach germ) in children, to see which works best. It may help families by finding more effective or tolerable treatment options.
Shanghai, Shanghai MunicipalityAges 6–18 - NCT03378102RecruitingEarly Phase 1
AdV-targeted T cells for adenovirus after bone marrow transplant
This trial tests a custom immune cell treatment (T cells made to recognize adenovirus) for people whose adenovirus infection is not improving or who cannot tolerate standard antiviral medicines after a bone marrow transplant. It aims to help your body control the virus and prevent organ complications.
Cleveland, OhioAges 3 months+ - NCT03394365RecruitingPhase 3
Tabelecleucel for EBV-related lymphoma after transplant treatment failure
This trial tests tabelecleucel, an immune therapy, for people whose EBV-associated post-transplant lymphoproliferative disease (PTLD) did not respond to rituximab and/or chemotherapy. It may help your immune system better control EBV-driven lymphoma after a transplant.
Duarte, CaliforniaAges Any age - NCT03401398RecruitingPhase 3
Hydrocortisone for children with septic shock in the ICU
This Phase 3 trial tests whether giving stress-dose hydrocortisone can improve outcomes for children with septic shock in the pediatric intensive care unit (PICU). It is designed for children who are already receiving strong medicines to support blood pressure because of a serious infection.
Tucson, ArizonaAges 1 month–17 years - NCT03413683Recruiting
Studying frailty in older adults living with HIV
This study looks at frailty (feeling weak, having trouble with daily activities, or losing strength) in people age 50 and older who are living with HIV. It may help researchers understand frailty in HIV and how to better support older adults.
ShatinAges 50 years+ - NCT03418441Recruiting
Study infections of the brain and spinal fluid in Denmark
This trial focuses on people in Denmark who may have an infection in the brain or the fluid around the brain and spinal cord. Researchers aim to collect and compare diagnostic results for different infection types (viral meningitis, bacterial meningitis, encephalitis, and others) to help confirm the cause and guide care.
AalborgAges 18 years+ - NCT03449706Recruiting
Tracking immune changes in early HIV
This study looks closely at how your immune system and HIV infection markers change right after a new HIV diagnosis. It may help doctors understand the earliest stages of HIV and improve how infections are measured and followed over time.
Ghent, Oost-VlaanderenAges 18–65 - NCT03450005Recruiting
CandiReg registry for invasive Candida infections
This study is a hospital registry that collects health and test information about people with confirmed invasive Candida (a fungal infection). It may help doctors understand who gets these infections and how they spread, which can improve future diagnosis and care.
Cologne, North Rhine-WestphaliaAges Any age - NCT03465683Recruiting
Study of germ carriage that produces ESBL enzymes
This study looks at whether certain bacteria that carry ESBL enzymes are spreading between people. To join, you would need lab-confirmed evidence that you carry these bacteria based on routine samples taken during usual care.
BaselAges 1 year+ - NCT03474029RecruitingPhase 2/Phase 3
Daily rifapentine treatment test for latent tuberculosis infection
This trial studies whether taking rifapentine every day is safe and helps prevent active tuberculosis (TB) in people who have latent TB infection. It aims to find the best way to stop TB from becoming a serious illness later.
Denver, ColoradoAges Any age - NCT03476941RecruitingPhase 2
Antibiotic wash for abscesses with a drain
This Phase 2 study tests whether putting antibiotic fluid through a drain helps treat an abscess inside the abdomen after it’s been drained. It may help improve infection control while the drain is in place.
Iowa City, IowaAges 18–80 - NCT03482245Recruiting
Study how body clock proteins affect immune responses in infections
This study looks at how your body’s daily “clock” proteins may influence your immune response during certain serious infections requiring hospital care. If you qualify, researchers will compare immune signals during treatment to better understand what could improve care.
St Louis, MissouriAges 18–65 - NCT03491605Recruiting
Follow-up study for people with high EBV virus levels
This study tracks health outcomes over time in people who have a high level of the EBV virus in their blood. It may help researchers understand what happens in chronic (long-lasting) EBV infection and which outcomes to watch for.
Wuhan, HubeiAges Any age - NCT03492762RecruitingEarly Phase 1
PET scan study of lung inflammation in never or current smokers
This early research study uses special PET scans to look at lung inflammation linked to a target called CCR2. It may help researchers understand inflammation biology and future treatments, using scan results instead of an investigational drug.
St Louis, MissouriAges 21 years+ - NCT03509961RecruitingPhase 2
Reducing total body radiation for children with leukemia transplants
This study looks at whether some children and young adults with B-ALL can safely get a transplant without total body irradiation (TBI), based on special leukemia test results. It’s meant to help lower radiation-related risks while keeping leukemia control strong.
Birmingham, AlabamaAges 1–25 - NCT03515031Recruiting
Compare two oxygen masks for breathing failure from pneumonia
This trial compares two ways of giving oxygen—high-flow nasal tubes versus a Venturi face mask—for adults with pneumonia causing acute breathing failure. It aims to see which method works better to improve breathing and recovery.
BergamoAges 18 years+ - NCT03524222Recruiting
Home hospital care for adults after sudden illness
This trial tests whether certain adults can safely receive hospital-level care at home instead of staying in the hospital, using a home care team. It may help you recover in your own home if your condition fits their plan and you have support at home.
Boston, MassachusettsAges 18 years+ - NCT03527433Recruiting
