Type IV hypersensitivity disease

This study tests whether a stem cell transplant can cure people with serious immune system disorders. Participants, aged 4 to 69, receive healthy donor stem cells to rebuild their immune system. The goal is to see if the transplant can permanently fix the immune defect and elimin…

This study tests whether a stem cell transplant from a healthy donor can help people with severe primary immunodeficiencies. Participants aged 4 to 75 receive chemotherapy before the transplant to prepare their body. The goal is to see if the procedure is safe and can improve imm…

This study tests a drug called soquelitinib in 15 people aged 16 and older with autoimmune lymphoproliferative syndrome (ALPS). The goal is to see if the drug can shrink an enlarged spleen or lymph nodes and improve low blood cell counts. Participants take the pill twice daily fo…

This phase 2 study tests whether giving emapalumab or a combination of fludarabine and dexamethasone before a stem cell transplant can reduce inflammation and help the donated cells take hold better. The trial involves 39 people with primary immune regulatory disorders or autoinf…

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 study looks at the safety of a nasal spray called neffy compared to a standard epinephrine shot for treating allergic reactions. It involves 600 people aged 4 and older who have an allergic reaction during a food challenge or allergy shot session. The goal is to see if the s…

Researchers at Peking University First Hospital are building a prospective cohort of 2,000 people with plasma cell disorders, including multiple myeloma, amyloidosis, and related conditions. Participants give blood, bone marrow, and urine samples before and after treatment, and t…

This study follows people with autoimmune lymphoproliferative syndrome (ALPS) and their relatives over many years. Researchers will collect blood and tissue samples, track symptoms, and study genetics to better understand why the immune system attacks the body. The goal is to lea…

This study will follow 30 adults who have received vaccines or antibody treatments for COVID-19 or monkeypox. Researchers will take blood and optional nasal swabs over time to measure how well the body's antibodies neutralize these viruses. The goal is to better understand how lo…

This study creates a registry for adults with plasma cell disorders, such as multiple myeloma and amyloidosis. Researchers will collect health information and optional blood samples to better understand these conditions. The goal is to gather data that could support future resear…
