💬In plain words
What the trial is, and whether it could suit you
Background:
CGD is caused by a gene mutation. For people with CGD, their cells cannot kill germs well, so they can get frequent or life-threatening infections. Researchers want to see if a new procedure can help a person s cells kill germs for a short time. It uses messenger RNA (mRNA) to deliver correct instructions for the gene mutation to the cells.
Objective:
To test a procedure in which mRNA is added to a person s blood cells.
Eligibility:
Males aged 18-75 with CGD with a mutation in the gene that makes the protein gp91phox.
Design:
Participants will be screened with:
Medical history
Physical exam
Blood and urine tests
Swab to test for strep throat
Some screening tests will be repeated during the study.
Participants will be admitted to the NIH Clinical Center hospital for at least 7 days. They will have apheresis. For this, a medicine is injected under their skin to pre

📋 Eligibility rules (as published)
* INCLUSION CRITERIA:
Individuals must meet all of the following criteria to be eligible for study participation:
* Males aged 18 to 75 years
* CGD confirmed by DHR and deficiency subtype confirmed by protein analysis and/or genetic sequencing
* Has a physician at home for follow-up care
* Able to provide informed consent
* For men who engage in activities that can result in pregnancy, agree to use contraception when engaging in sexual activities that can result in pregnancy. Contraception must be used from screening through 3 months after the CGD-Grans infusion. Acceptable methods of contraception include the following:
* Hormonal contraception
* Male or female condom
EXCLUSION CRITERIA:
Individuals meeting any of the following criteria will be excluded from study participation:
* Clinically unstable due to moderate to severe acute systemic infections as defined by persistent resting tachypnea, tachycardia, or hypoxia of \>20% from baseline and hypotension.
* Current or history of stage 4 chronic kidney disease or estimated glomerular filtration rate \[eGFR\] \<30 mL/min/1.73 m\^2 within 90 days of baseline.
* Unstable diabetes mellitus with hemoglobin A1c \>7.0% and fasting serum glucose \>200 mg/dL at screening.
* Current or history of heart failure stage D as defined by the American College of Cardiology Foundation/American Heart Association guidelines.
* History of arrhythmias that are symptomatic and deemed clinically unsafe for participation by NIH CC Cardiology consultation.
* Current or history of invasive cancers that require chemotherapy within 5 years of screening.
* Active hepatitis B, C, or HIV infections at screening.
* Unstable hypertension requiring addition of new anti-hypertensives within 2 weeks of screening.
* Impaired renal function that is unstable, with serum creatinine \>3.0 mg/dL and rising.
* Serum transaminases and bilirubin that are \>3 x the upper limit of normal.
NOTE: For prospective subjects who, per PI assessment at screening, have abnormal liver function tests, and/or a significant history of liver disease, and/or liver-related complications of CGD, and who otherwise meet eligibility criteria \[i.e. those who do NOT meet any of the exclusion set forth herein\], a hepatology consult will be required at screening, and participation must be approved in writing by hepatology to the PI.
* Electrocardiogram abnormalities indicative of acute myocardial injury, or arrhythmias that presents anesthetic risks, at screening.
* Anemia with hemoglobin \<8 g/dL (transfusions to correct anemia permitted).
* Thrombocytopenia (platelets \<50 x10\^9 cells/L) (platelet transfusions to correct thrombocytopenia permitted).
* Profound thrombocytopenia (platelet counts \<10,000/microliter) that is not reversible with platelet transfusions.
* Abnormal prothrombin time/partial thromboplastin time (PT/PTT) values outside the ranges accepted at the NIH CC that are not corrected or that cannot be attributed to presence of Lupus anticoagulant (commonly found in CGD patients).
* Inherited bleeding disorder that precludes line placement.
* Severe oxygen-dependent pulmonary disease that increases risks of procedures that may require sedation.
* History of or current evidence of alcohol or illicit drug abuse or dependence.
* Participation in a clinical protocol that includes an intervention that, in the opinion of the investigator, may affect the results of the current study.
Subjects will be selected in an equitable manner from the available pool of potentially eligible individuals, without regard to factors such as gender, race, ethnicity, socioeconomic status, etc, except for age and sex.
