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+ - NCT01558804Recruiting
Study for children with strep throat using beta-lactam antibiotics
This study looks at children ages 5–15 who test positive for Group A strep (often called strep throat). It may help by testing an antibiotic approach with beta-lactam medicines for children who are expected to need treatment.
Madison, WisconsinAges 5–15 - 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 - NCT01868373Enrolling by invitationPhase 1
Fecal transplant study for hard-to-treat C. difficile diarrhea
This Phase 1 study tests defined fecal microbiota (healthy gut bacteria) given to people with C. difficile diarrhea that didn’t go away or came back soon after antibiotics. It may help by restoring a healthier balance of gut bacteria so the infection can stop recurring.
Houston, TexasAges 18 years+ - 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+ - NCT02048332RecruitingPhase 1/Phase 2
Donor immune cells for preventing infections after stem cell transplant
This trial studies donor-made immune cells (T-cells) given after a stem cell transplant to help your body fight infections. It aims to test how safe the treatment is and whether it supports the immune system in the months after transplant.
Akron, OhioAges 4 weeks+ - NCT00571389Recruiting
Collecting blood cells from people with cancer or COVID-19
This study collects blood cells using a special blood-draw procedure called leukapheresis (for some participants) and other samples. It aims to better understand cancer and immune-related cells, which may help researchers design or improve future treatments.
Huntersville, North CarolinaAges 5 years+ - NCT00411983Recruiting
Long-term follow-up for people in the HIV-NAT studies
This study checks in with people who have joined HIV-NAT research in the past or are joining it now, to learn how their HIV and treatment outcomes look over time. It may help improve future care and research for people living with HIV.
BangkokAges 18 years+ - NCT00187512Recruiting
Study of how HIV treatment changes outcomes over time
This is an observational study (not a new drug) that tracks how living with HIV can change over time in different treatment situations. It may help researchers understand long-term effects of the modern “protease inhibitor era” and improve future care.
San Francisco, CaliforniaAges 18 years+ - 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 - NCT01202305Recruiting
Lymph node biopsies to study HIV in different patients
This study uses a small tissue sample from an often-accessible lymph node to learn how HIV affects the body. It may help researchers understand why some people control HIV better than others.
San Francisco, CaliforniaAges 18–70 - NCT00796146Recruiting
Study people newly infected with HIV to learn early changes
This study enrolls adults with a very recent (“acute”) HIV infection to follow them over time and better understand what happens early after infection. Your participation may help researchers improve how acute HIV is detected and managed.
Bangkok, BangkokAges 18 years+ - NCT01137825Recruiting
Older patient cancer registry for a health check
This study is a registry that collects information from older adults who may be dealing with cancer. It includes a short health and function check to help doctors understand needs and guide care, even for people who turn out not to have cancer.
Boone, North CarolinaAges 65 years+ - NCT01244802Enrolling by invitation
Study of immune memory after yellow fever vaccination
This study looks at how your immune system “remembers” the yellow fever vaccine over time. It may help researchers understand long-term immune protection and how it varies between people.
Decatur, GeorgiaAges 18 years+ - NCT00704626Enrolling by invitation
Blood antibody tests in autoimmune brain and nerve diseases
This study looks at blood “auto-antibodies,” which are immune proteins that may attack the body, in people with certain brain and nerve conditions. It may help researchers better understand these diseases and how the immune system is involved.
Sacramento, CaliforniaAges 18 years+ - NCT01161199Recruiting
Leukapheresis study in people living with HIV
This trial uses a special blood-filtering procedure (leukapheresis) along with blood tests to better understand how HIV affects the body. It may help researchers learn more about HIV “pathogenesis,” which means what drives disease in different people.
San Francisco, CaliforniaAges 18 years+ - NCT00307281Recruiting
Emphysema and COPD patient registry with sample storage
This study enrolls people who have emphysema/COPD into a research registry and collects health information and biological samples. It may help researchers understand the disease better and improve future treatments.
Pittsburgh, PennsylvaniaAges 21 years+ - NCT00032513Recruiting
Genetic study of chronic active Epstein-Barr virus disease
This research study looks for genetic factors that may explain why some people develop severe, long-lasting Epstein-Barr virus (EBV) infection. Researchers will study blood and tissue samples from patients with this rare condition, their healthy relatives, and unrelated volunteers to understand the disease better.
Bethesda, MarylandAges 1–120 - NCT00001971Recruiting
Evaluation of patients with liver disease
This research study evaluates people with liver disease or at risk for liver disease, and compares them with healthy volunteers. The goal is to better understand liver disease and improve how doctors diagnose and treat it.
Bethesda, MarylandAges 2–100 - NCT00001355Recruiting
Understanding immune system cell defects and family patterns
This research study investigates problems with immune system cells called phagocytes that help fight infections. Researchers will study patients with suspected immune defects and their blood relatives to better understand these conditions and develop better care.
Bethesda, MarylandAges 1 month–100 years - NCT00001352Recruiting
Understanding Why Some People Get Fungal Infections
This study looks at genetic reasons why some people are susceptible to a serious fungal infection called cryptococcosis. Researchers will collect blood samples and perform genetic testing to understand the immune system differences that make certain individuals more vulnerable to this infection.
Bethesda, MarylandAges 18–99 - NCT00001316Recruiting
Study viral levels in blood and lymph node tissue with HIV
This study measures how much HIV is in your blood and lymph node tissue. If you qualify, you would also allow blood and other tests (including genetic and hepatitis screening), which may help researchers better understand how HIV affects the body.
Bethesda, MarylandAges 18–100 - NCT00001778Recruiting
Understanding HTLV Infection and HAM/TSP Disease
This research study evaluates people with HTLV infection, a virus that can cause a nerve disorder called HAM/TSP. Researchers want to better understand who gets this condition and why, which may help develop future treatments.
Bethesda, MarylandAges 18–120 - NCT00018044Recruiting
Study of mycobacterial infections and immune system
This study looks at how the body fights mycobacterial infections (a type of bacteria) and aims to find immune problems that make some people more prone to these infections. It may help us understand why some people get sick and could lead to better treatments.
