New study probes immune system in rare disease patients
NCT ID NCT06605378
First seen Jun 27, 2026 · Last updated Aug 18, 2026 · Updated 2 times
Summary
This study looks at how common certain antibodies and inflammatory markers are in people with chronic granulomatous disease (CGD). Researchers will measure levels of adenovirus-fighting antibodies and inflammatory cytokines in blood samples from 60 adults and children with CGD. The goal is to better understand the immune system in CGD, which may help guide future treatments.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * The participant must have been diagnosed with CGD based on the referring physician's confirmation that NADPH oxidase activity is ≤5% (i.e., the percentage of dihydrorhodamine-positive \[DHR+\] cells is ≤5% by flow cytometry) OR based on confirmed pathogenic mutation in a CGD associated gene (CYBB, CYBA, NCF1, NCF2, NCF4, or CYBC1). * The participant or the participant's legally authorized guardian or representative (if applicable) must be capable of giving signed informed consent. * The participant (with assistance from the participant's legally authorized guardian/representative or primary caregiver, if applicable) must be capable of complying with the requirements and restrictions listed in the protocol and informed consent form (ICF). Exclusion Criteria: * The participant has undergone an allogeneic bone marrow transplant or investigational gene therapy. * The participant is unable to comply with the sample collection procedure based on investigator judgment.
