The Mechanistic Biology of Primary Immunodeficiency Disorders

Plain-language summary
Background:
Primary immunodeficiency disorders, or PIDs, are diseases that weaken the immune system. This makes it easier for a person to get sick. Some PIDs are mild and may not be diagnosed until later in life. Other kinds are severe and can be identified shortly after birth. Researchers want to learn more about PIDs by comparing data from relatives and healthy volunteers to people with a PID.
Objective:
To learn more about PIDs, including their genetic causes.
Eligibility:
People ages 0-90 with a PID or their healthy biological relatives the same ages
Healthy volunteers ages 18-75
Design:
Participants will be screened with a medical history, physical exam, and HIV blood test. They may have a pregnancy test.
Participants may repeat the screening tests.
Blood taken at screening will be used for genetic tests and research tests. Participants will be told test results that affect their health. Some blood will be stored for future research.
Adult participants with a PID may have a small piece of skin removed. The area will be numbed. A small tool will take a piece of skin about the size of a pencil eraser.
Researchers may collect fluid or tissue samples from PID participants regular medical care. They will use them for research tests.
Participants with a PID will have 3 follow-up visits over 10 years (for infants, 2 years). Visits will include a physical exam, medical history, and blood draw.
Participants with a PID and their relatives will be called once a year for 10 years. They will talk about how they are feeling and if they have developed any new symptoms or illnesses.

Inclusion criteria
. Subjects must meet one of the following 4 criteria:
. Patients (age 0-90 years) with a clinical diagnosis of a form of PID (either known or unknown). PID is defined by laboratory and/or clinical findings on two or more occasions that are consistent with a defect in innate or adaptive immunity. Specific PIDs are defined by the International Union of Immunological Societies guidelines. These subjects must also be willing to undergo genetic testing and to allow their biospecimens to be modified into iPS cells. Women of childbearing potential, or who are pregnant or lactating, may be eligible. The volume of blood collected for research purposes will be reduced, and no skin biopsies will be performed for research purposes in consideration of their safety.
. Infants identified at birth with positive newborn screening for SCID and confirmed to have T-cell lymphocytopenia. These subjects must be willing to undergo genetic testing.
. Biological relatives (age 0-90 years) of a subject who meets criterion 1a or 1b but who do not have a PID themselves. All relatives must be willing to undergo genetic testing. Women of childbearing potential, or who are pregnant or lactating, may be eligible. The volume of blood collected for research purposes will be reduced in consideration of their safety.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Identification of unique clinical phenotypes associated with known genetic causes of PID.
Timeframe: 10- 15 years
2
Identification of genetic variants that are associated with PID.
Timeframe: 10-15 years
Trial details
NCT IDNCT03394053
SponsorNational Institute of Allergy and Infectious Diseases (NIAID)
. Healthy volunteers (age 18-75 years) who are not related to another study subject, who do not have a PID, whose weight is greater than 110 pounds, do not have a history of any heart, lung, or kidney disease, or bleeding disorders, do not have a history of viral hepatitis (B or C), and have a negative HIV screening test.
. All subjects must be willing to allow their samples to be stored for future research.
Exclusion criteria
. Subjects with secondary causes of immunodeficiency are excluded from this study. Secondary causes of immunodeficiency include HIV infection and immunodeficiency that is deemed to be secondary to chronic use of immunosuppressive medications or chemotherapeutic agents.
. Any condition that, in the opinion of the investigator, contraindicates participation in this study.
