This study tests a new drug called TCC1727 combined with other medicines (benmelstobart, olaparib, or topotecan) in people with advanced solid tumors, including lung, stomach, endometrial cancer, and melanoma. The goal is to find the safest dose and see if the combination helps s…

This study tracks 50 children and adults with non-malignant disorders like immune deficiencies and anemias who receive a stem cell transplant after a reduced-intensity chemotherapy regimen. The goal is to see if this approach improves survival and reduces severe graft-versus-host…

This study is testing a less intense chemotherapy and radiation regimen before a stem cell transplant for children and young adults up to age 55 with non-cancerous blood disorders like immune deficiencies, anemias, and metabolic diseases. The goal is to see if this gentler prepar…

This trial tests a gene therapy for children with X-linked severe combined immunodeficiency (SCID-X1), also known as 'bubble boy' disease. Participants receive a low dose of busulfan followed by an infusion of their own blood stem cells that have been genetically corrected with a…

This program offers extra stem cells from a half-matched family donor to patients who are getting a cord blood transplant for serious blood cancers or immune disorders. The goal is to help the bone marrow recover more quickly while the cord blood cells take over permanently. It i…

This study tests whether daily treatments with slightly elevated carbon dioxide (hypercapnia) can improve breathing and reduce sleep apnea in Veterans with spinal cord injury. About 30 adults with chronic spinal cord injury or able-bodied people with sleep apnea will receive the …

This study is looking for the genes that cause certain immune system problems. Researchers want to understand why some people get sick and others don't, even in the same family. Up to 5,000 people with immune disorders and their relatives will give blood or cheek cell samples for…

This study aims to learn more about how diseases related to blood clots, the immune system, and blood vessels start and change over time. Researchers will enroll up to 1,000 people aged 5 and older, including those with these conditions, their healthy relatives, and healthy volun…

This study is observing up to 3,500 people with immune system problems, including rare genetic conditions like chronic granulomatous disease and severe combined immunodeficiency. Researchers will track how these diseases change over time through blood tests, imaging, and checkups…

This study looks at the tiny organisms living on our skin—like bacteria and fungi—and how they might differ in people with eczema (atopic dermatitis). Researchers will collect skin samples from healthy volunteers and patients aged 2 to 40 with moderate to severe eczema, as well a…
