- 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+ - NCT02898987Recruiting
Study quality of care for adults living with HIV
This trial looks at how care is being provided to adults with HIV who may be on treatment or not, and regardless of immune strength. It may help improve future care plans by identifying what works best in real-world settings.
BelfortAges 18 years+ - NCT02761200Recruiting
Study pause of HIV treatment in people already enrolled
This study looks at what happens when HIV treatment (ART) is intentionally paused in people who are already enrolled in a specific research study (RV254) and recently joined a protocol that included an earlier treatment pause. It may help researchers understand safety and how to manage treatment changes, but it has strict participation and consent requirements.
Bangkok, BangkokAges 18 years+ - NCT02699736Enrolling by invitation
HIV and hepatitis C study in European adults
This study follows people living with HIV who also have hepatitis C antibodies, to better understand how HIV and hepatitis C affect health over time. You may be able to join if you meet the age and enrollment requirements, even if your hepatitis C virus level is currently undetectable.
Buenos AiresAges 16 years+ - NCT02877303RecruitingPhase 2
Frontline drug treatment for newly diagnosed B-cell leukemia
This trial tests a combination of targeted and chemotherapy medicines as first treatment for newly diagnosed B-cell acute lymphoblastic leukemia (ALL) or related lymphoblastic lymphoma. It aims to improve how well treatment controls the leukemia and how long people can stay in remission.
Houston, TexasAges 14 years+ - NCT02738645Recruiting
Study of pneumonia patients in the ICU
This study follows people who are admitted to a respiratory intensive care unit (a special ICU for breathing problems) because they have pneumonia. It may help doctors better understand pneumonia in ICU patients and improve care in the future.
Beijing, Beijing MunicipalityAges 18 years+ - NCT02996656Recruiting
Antibiotic prevention for skin bacteria in shoulder surgery
This study checks whether giving an antibiotic “ahead of surgery” can reduce problems from common skin bacteria (Propionibacterium acnes) during primary shoulder surgery. It may help lower the risk of infection around the new joint/repair.
Montreal, QuebecAges 18 years+ - NCT02863757Recruiting
Follow-up study for chronic hepatitis B with fatty liver
This study follows people who have chronic hepatitis B and also have fat buildup in the liver (nonalcoholic fatty liver disease). It’s looking at how these conditions behave over time and what may help, using information collected during follow-up visits.
Hong Kong, Hong KongAges Any age - NCT02190266Recruiting
Study genetics and cause of hard-to-treat Valley fever
This study looks at why “Valley fever” is difficult to treat or has spread beyond the lungs, and how a person’s genetics may be involved. You may be asked for blood or other samples for genetic testing and for storing samples for future research.
Bethesda, MarylandAges 2–100 - NCT02471378Recruiting
Testing a malaria vaccine in pregnant people with malaria
This study looks at lab tests for malaria vaccine candidates in pregnant women who currently have malaria. It may help researchers understand which vaccine approaches are safest and most promising for pregnancy.
BamakoAges 15–25 - NCT02511002Enrolling by invitation
Long-term follow-up after an influenza challenge study
This study keeps track of how your body’s immune responses change over time after an influenza exposure. Researchers may use stored blood samples to study specific antibody levels, which could help improve future flu vaccines or treatments.
Bethesda, MarylandAges 18–120 - NCT02639299Recruiting
Screening healthy adults for malaria vaccines and drug studies
This study screens healthy adults to see who can join future malaria vaccine or investigational malaria drug studies, including a controlled malaria exposure. It may help researchers test safer vaccines/drugs, but participation requires good health and strict medical eligibility.
Bethesda, MarylandAges 18–50 - NCT02435810Recruiting
Study of infections and inflammation affecting the nervous system
This study looks at how infections or inflammation involving the brain and spinal cord work, using patient data and samples. It may help researchers better understand these illnesses and improve future care.
Bethesda, MarylandAges 2–110 - NCT02471352Recruiting
Share skin samples for dermatology research
This study collects and stores biological samples (biospecimens) from people with skin conditions, people at risk, or healthy volunteers. It helps researchers better understand dermatologic diseases and support future skin research.
Bethesda, MarylandAges 1 day–100 years - NCT02579967RecruitingPhase 2
Stem cell transplant for primary immune system disorders
This study tests whether an allogeneic stem cell (bone marrow) transplant can correct an inherited immune problem in people with severe primary immunodeficiencies. It may help reduce life-threatening infections and improve quality of life, depending on your overall health and donor match.
Bethesda, MarylandAges 4–75 - NCT02200276Recruiting
Flu shot study for adults over 75
This study looks at getting an influenza (flu) vaccine in adults age 75 and older. It may help doctors understand how to safely give flu shots to older adults.
Baltimore, MarylandAges 75 years+ - NCT02437981Enrolling by invitation
PrEP for HIV prevention in high-risk adults in Thailand
This trial checks how well PrEP pills (TDF/FTC) prevent HIV in people who are at high risk and are HIV-negative. It may help you understand whether PrEP is a good prevention option for your situation.
Bangkok, PathumwanAges 18 years+ - NCT02545478Recruiting
Testing blood markers in people with and without infection
This study looks at blood test “markers” to tell the difference between infection and non-infectious illness. It may help doctors recognize infection earlier and avoid confusion with other conditions.
Boston, MassachusettsAges 18 years+ - NCT02456974Recruiting
Testing how antibiotics are dosed in children’s intensive care
This study looks at whether giving common antibiotics in certain dose schedules (either through a drip over time or continuously) is done in a way that fits pediatric intensive care needs. It may help improve antibiotic treatment for children who are very sick and need antibiotics.
GhentAges 1 day–16 years - NCT02271243Recruiting
Find the source of bloodstream infections from central line germs
This study uses special genetic testing of bacteria from blood to figure out where central-line bloodstream infections come from. Results may help doctors better identify the source and improve prevention and treatment.
Boston, MassachusettsAges Any age - NCT02437526Enrolling by invitation
Testing an HIV treatment pause to see if cure is possible
This study looks at whether some people with HIV can keep the virus controlled even if they temporarily stop HIV medicines (an “analytic treatment interruption”). If you qualify, it may help researchers learn what it would take for an HIV cure.
Rochester, MinnesotaAges 18 years+ - NCT02532452RecruitingPhase 2
T-cells made to fight a specific virus
This Phase 2 study gives you special “virus-targeting” immune cells (T-cells) to help your body control a current viral infection or virus that has come back (reactivated). It may help reduce the virus activity while you are immunocompromised, meaning your immune system is weaker than usual.
Akron, OhioAges 2 days+ - NCT02357238Recruiting
Study of genetics in people with uveitis
This study looks at genetic (inherited) differences in people with uveitis. The goal is to better understand what may cause uveitis and potentially help with future treatments.
Cleveland, OhioAges 6 years+ - NCT02193295Recruiting
Testing how changing fats affects insulin resistance
This study tests how “lipid” (fat) changes in the body affect insulin resistance, which is when the body doesn’t respond to insulin as well as it should. Because it’s done in healthy people, it’s mainly looking at basic biology and may help guide future treatments.
