Study of causes and progression of low CD4 blood cells
This study looks for what causes and how idiopathic low CD4 cells happen over time, using blood and tissue samples. It may help doctors learn why this occurs and how to better track people with it.
Bethesda, MarylandAges 18 years+ - NCT01200953Recruiting
Study care after contact with serious infectious germs
This study helps doctors manage people who may have been exposed to, infected with, or are recovering from dangerous infectious germs (including emerging outbreaks). It may help by setting safe evaluation and care steps after these high-risk exposures.
Bethesda, MarylandAges 3–99 - NCT01905709Recruiting
Fecal transplant to treat recurring C. difficile infection
This trial studies using a fecal microbiota transplant (FMT)—healthy gut bacteria moved from a screened donor—to help treat recurring or hard-to-control C. difficile infection. It may help restore a healthier gut environment when standard treatments keep failing or the infection returns.
Englewood, New JerseyAges 18 years+ - NCT01212003Recruiting
Study of how tuberculosis develops over time
This study follows people with suspected or confirmed tuberculosis (TB), whether they have inactive “latent” TB or active TB. It helps researchers better understand TB’s natural course and may improve future testing and care by allowing collection and storage of samples.
Bethesda, MarylandAges 2–100 - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.
Sioux Falls, South DakotaAges Any age - NCT00341744Recruiting
Access to learning for children with low vision
This trial aims to help children with low vision access the visual environment needed for school, especially for learning to read. It may help by supporting how vision is used for reading in everyday school activities.
Nashville, TennesseeAges 3–21 - NCT00404989Recruiting
Pregnancy drug safety registry for people with HIV treatment
This trial is a pregnancy registry that collects information about birth outcomes when certain HIV medicines are taken during pregnancy. It helps detect any major birth defects so future pregnancies can be safer.
Wilmington, North CarolinaAges 12–60 - NCT01875588Recruiting
Long-term study of thinking and memory in adults with HIV
This study looks at how thinking and memory change over time in adults with HIV and compares them with adults without HIV. Researchers will do regular visits and brain/cognitive testing to understand what affects thinking and memory and to learn what might help.
Bethesda, MarylandAges 18–110 - NCT01829204Recruiting
Health study registry for vaginal conditions
This study is building a database (a secure record) to learn about vaginal/vulva conditions in women. You may be invited if you’re coming in for a routine women’s health visit or you’re being seen for a vaginal concern, and you can share information safely.
Midland, TexasAges 21–75 - NCT01520844Recruiting
HIV cohort study comparing people on and off treatment
This study follows adults with HIV over time to compare different groups based on how stable their virus levels are. It may help researchers understand who can safely interrupt treatment and who should stay on it, and how immune health changes.
Le Kremlin-BicêtreAges 18–85 - NCT02038166Recruiting
Measuring nasal function in adults with chronic sinus symptoms
This study tests a specialized way of measuring how your nasal lining responds in people with chronic rhinosinusitis (long-lasting sinus inflammation). The goal is to see whether the nasal measurement is usable and safe, and to help better understand chronic sinus disease.
Birmingham, AlabamaAges 18 years+ - NCT02007356RecruitingPhase 2
Donor immune cell infusions for viral infections after stem cell transplant
This trial studies whether directly infusing donor-made immune cells (virus-fighting T-cells) is safe and feasible in people who still have viral infections after a stem cell transplant. It may help your body control infections from adenovirus, CMV, or EBV when standard antiviral treatments aren’t working.
BaselAges 18–65 - NCT01940757RecruitingPhase 1
Testing hookworm infection for adults who have never had it
This early-phase study tests whether deliberately infecting you with hookworm larvae placed on the skin is safe and how your body responds. It may help researchers understand treatments for hookworm-related conditions, but it involves being intentionally infected.
Washington D.C., District of ColumbiaAges 18–45 - NCT00825929Recruiting
Drug levels in HIV treatment during pregnancy
This study measures how HIV medicines move through your body during pregnancy by collecting blood samples after you take your regular treatment. It may help improve understanding of dosing and drug levels in pregnant people living with HIV.
BrusselsAges 18 years+ - NCT01137643Recruiting
Sharing blood and tissue samples for blood cancer research
This trial collects tissue, blood, and other body fluid samples from people with blood-related cancers. The goal is to help researchers study these diseases by building a source of samples for future testing.
Chapel Hill, North CarolinaAges 18–120 - NCT01206920Recruiting
DC study following HIV prevention and care experiences over time
This study follows people who receive HIV care in Washington, DC and people using HIV prevention medicines (like PrEP) to understand health needs and outcomes over time. It may help improve how HIV care and prevention are delivered in local clinics.
Washington D.C., District of ColumbiaAges Any age - NCT01397669Recruiting
Study immune differences in HIV and HIV-negative adults
This research compares the immune system in the gut lining, spinal fluid, lymph nodes, and blood between people living with HIV and people not living with HIV. Results may help scientists understand how immunity works and how it differs with HIV.
Bangkok, BangkokAges 18–50 - NCT01371630RecruitingPhase 1/Phase 2
Inotuzumab plus chemotherapy for certain types of childhood-like leukemia
This early-phase trial studies how well a targeted drug (inotuzumab ozogamicin) combined with chemotherapy treats acute lymphoblastic leukemia (ALL). It may help people with newly diagnosed ALL who may not tolerate standard intensive chemotherapy, especially older adults.
Houston, TexasAges 18 years+ - NCT01492036Recruiting
Long-term follow-up for people who received gene therapy
This study follows people for many years after they receive gene therapy (a treatment that uses lab-made genetic material). It mainly checks long-term safety and health outcomes and may help doctors understand how gene therapy works over time.
Houston, TexasAges Any age - NCT01913132Recruiting
PICO study after groin surgery incisions
