Functional neutrophil defect

This study tests an experimental drug called AVTX-803 in people with leukocyte adhesion deficiency type II (LAD II), a rare genetic condition that weakens the immune system and leads to frequent infections. The trial will compare the drug against a period without treatment to see…

This phase 3 study is testing the long-term safety and effectiveness of AVTX-803, a form of L-fucose, in people with leukocyte adhesion deficiency type II (LAD II), a rare genetic disorder that weakens the immune system. Only 2 participants who completed a previous study are enro…

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…

Researchers at Johns Hopkins University are studying whether neuromuscular ultrasound and MRI can serve as reliable markers of swallowing muscle problems in people with inclusion body myositis (IBM). The study compares imaging and clinical findings in 30 participants, including p…

This study collects blood stem cells from adults aged 18-40 with DOCK8 deficiency, LAD-1, or GATA2 deficiency. Participants receive daily injections of G-CSF for 5 days to move stem cells into the blood, then undergo a single leukapheresis procedure to collect them. The cells are…

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 aims to understand why some people are more prone to fungal infections, especially from Candida yeast. Researchers will collect blood, saliva, urine, and tissue samples from people with immune disorders, their family members, and healthy volunteers. No treatment is giv…

This study is building a large database of health information from 5,000 people with ALS and other motor neuron diseases. Participants share details like symptoms, test results, and disease progression during regular clinic visits. The de-identified data is then shared with resea…
