Deltaretrovirus infections

This study tests a stem cell transplant to control peripheral T-cell lymphoma in people whose cancer has not responded to standard treatments. Participants receive a donor's stem cells after chemotherapy or antibody therapy to prepare their body. The goal is to see if this approa…

This early-stage trial tests a new gene therapy for certain T-cell lymphomas that have come back or not responded to treatment. The therapy uses a patient's own white blood cells, modified to attack cancer cells that carry a protein called CCR4. Up to 60 adults will receive the m…

This Phase 2 trial compares the drug dolutegravir alone versus dolutegravir combined with tenofovir in 146 adults with HTLV-1 infection and related symptoms. The main goal is to see if the combination lowers the virus level more effectively and improves pain, spasticity, and musc…

This study tests a new treatment called OJP-001 for people with adult T-cell leukemia/lymphoma (ATLL) that has come back after prior therapy. The treatment uses a light-sensitive drug and a machine to treat the blood outside the body, aiming to kill cancer cells. The study will c…

This study tests whether using early drug monitoring and a dose-adjustment calculator can help infants under 90 days old with sepsis reach target vancomycin levels more quickly. Currently, doctors must wait 24-48 hours to check drug levels, which can delay effective treatment. Th…

This phase II trial is testing whether the drug ruxolitinib, taken as a daily pill after a stem cell transplant, can help prevent T-cell lymphoma from coming back and reduce the risk of graft-versus-host disease (GVHD). The study will enroll 44 adults with various T-cell lymphoma…

This study tests whether giving patients donor-derived immune cells (VSTs) on a regular schedule can prevent dangerous viral infections after a stem cell transplant. 180 participants will be randomly assigned to receive VSTs either on a fixed schedule or only when a virus is dete…

This early-phase trial is testing a combination of donor natural killer (NK) cells and the drug mogamulizumab in 12 patients with relapsed or refractory cutaneous T-cell lymphoma or adult T-cell leukemia/lymphoma. The NK cells are grown in the lab and given 'off the shelf' to boo…

This study compares two ways of giving the antibiotic cefepime to very sick patients with sepsis in the ICU. The new method adjusts the dose based on the patient's kidney function, using only standard doses. The main goal is to see if this approach is easy for doctors to use and …

This study tests whether specially grown donor immune cells (viral-specific T-cells) can safely treat viral infections that often occur after a stem cell transplant. These infections can be serious and sometimes don't respond to standard antiviral drugs. The approach aims to boos…

This study tests whether giving zinc supplements along with standard antibiotics can reduce deaths and improve recovery in young infants (0-59 days old) hospitalized with severe infections like sepsis or pneumonia. About 3,250 babies in Tanzania will receive either zinc or a plac…

This phase 2 trial tests a two-step, lower-intensity transplant method for people with various blood cancers. The goal is to see if this gentler approach reduces the chance of dying from the transplant itself. About 63 participants will receive a combination of radiation, chemoth…

This phase 2 trial is testing a five-drug combination for a rare, aggressive type of T-cell leukemia called ETP-ALL. The study aims to see if this mix can help more patients achieve remission after their first treatment. About 27 newly diagnosed adults will receive the drugs, and…

This study tests whether the drug mogamulizumab can prevent adult T-cell leukemia/lymphoma (ATL) in people infected with HTLV-1 who are at high risk. About 134 participants will receive low doses of the drug over several weeks. The goal is to see if it can reduce the virus levels…

This study follows people infected with HTLV-I virus, some of whom develop a rare spinal cord condition called HAM/TSP. Researchers will track changes in symptoms, immune system markers, and virus levels over time. The goal is to better understand why only a few infected people g…

This study looks at how the immune system changes with age and how that affects the risk of infections in people 60 and older. Researchers will collect blood, urine, stool, and other samples from elderly patients with infections and healthy older adults. By analyzing immune cells…

This study collects blood, bone marrow, and tumor samples from 500 adults with cancer or pre-cancerous conditions. Researchers will use these samples to learn more about how cancers behave and why some respond differently to treatments. Participants provide samples over time and …

This study collects blood, urine, bone marrow, and tissue samples from over 1,200 adults with lymphoid cancers or precancerous conditions. The goal is to help researchers better understand cancer biology, which may lead to new methods for diagnosing or treating these diseases. No…

This study aims to improve how doctors evaluate and manage people who have been exposed to bioterrorism agents (like anthrax) or emerging infectious diseases (like SARS or new flu strains). Up to 200 participants, including patients and healthcare workers, will be monitored and t…

This study collects blood, urine, bone marrow, and tumor samples from people with hairy cell leukemia and other blood cancers, as well as from healthy volunteers. Researchers will use these samples to study the diseases and develop new treatments called immunotoxins, which use an…

This study is creating a large database of information and tissue samples from 1,000 people with T-cell lymphoma. Researchers will use this data to learn more about the disease and how to improve patient outcomes. Participants provide medical information and optional blood and na…

This study tests a new, lightweight ultrasound device called NeoDoppler that can be gently placed on a newborn's soft spot (fontanelle) to continuously measure blood flow in the brain. Researchers will enroll 180 preterm and full-term infants, including those with conditions like…

This study is looking at whether early signs of inflammation in the blood can help identify which patients with infections are at risk for serious complications like sepsis. Researchers will follow 4,200 adults with confirmed or suspected infections, as well as healthy controls, …

This study looks at how the antibiotic ceftazidime avibactam behaves in 30 children with severe infections who are in intensive care, some on life support. Researchers will measure drug levels in the blood to understand the right dose. The goal is to improve treatment for life-th…

This study looks at how the antifungal medicine caspofungin behaves in children with severe infections, especially those with liver problems or on life support like ECMO. Researchers will measure drug levels in the blood to understand dosing needs. About 60 children in intensive …

This study will collect data from 2,000 children admitted to pediatric intensive care units (PICUs) with severe infections across major Chinese cities. Over 10 years, researchers will track which germs cause these infections, how they are treated, and patient outcomes. The goal i…

This study looks at two common antibiotic combinations given to hospitalized adults with infections: vancomycin plus piperacillin-tazobactam, or vancomycin plus cefepime. The goal is to see if one is less likely to cause kidney injury than the other, using more sensitive markers …

This study looks for new ways to kill T-cell leukemia and lymphoma cells by disrupting their internal balance of reactive oxygen species. Researchers will test drug combinations in lab-grown cells and in samples from 120 patients with resistant disease. The goal is to find treatm…
