NCT ID NCT06605378

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.
