  • 02 Confirmed diagnosis of CGD due to p47phox deficiency (confirmed mutation in the NCF1 gene by molecular genetic testing).
  • 03 Absent or > 95% reduced biochemical activity of NADPH oxidase in a dihydrorhodamine flow cytometric test.
  • 04 Male or female aged ≥ 18 months and have a body weight ≥ 10 kg the time of signing the informed consent or assent.
  • 05 One or more ongoing or recurrent severe infectious and/or inflammatory complications, at the discretion of the Investigator.

You likely can't join if

  • 01 Participant or parent/legal guardian is unable or unwilling to comply with the protocol requirements
  • 10 Inability to stop using interferon-gamma at least 30 days prior to administration of the study intervention.
  • 11 Participation in another interventional clinical study within 6 months prior to enrolment.
  • 12 Presence of any condition that, in the opinion of the Investigator, may compromise the safety or compliance of the participant or would preclude the participant from successful completion of the study or would interfere with interpretation of the study results.
  • 02 Availability of a willing 10/10 HLA-matched (A, B, C, DR, DQ) sibling donor unless there is an unacceptable risk associated with an allogeneic HSCT procedure.
  • 03 Previous allogeneic HSCT.
