New treatment option for Severe Combined Immunodeficiency
Official title Autologous Gene Therapy for Artemis-Deficient SCID
ClinicalTrials.gov ID: NCT03538899
What this study is testing
What is AProArt-CD34?
AProArt-CD34 is an investigational medicine, given as an once-weekly infusion into a vein, being studied as a potential treatment for severe combined immunodeficiency.
Also referred to as lentiviral gene therapy using AProArt.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study aims to determine if a new method can be used to treat Artemis-deficient Severe Combined Immunodeficiency (ART-SCID), a severe form of primary immunodeficiency caused by mutations in the DCLRE1C gene. This method involves transferring a normal copy of the DCLRE1C gene into stem cells of an affected patient.
- Phase 2: a mid-size study of how well it works
- Which group you join is decided by chance.

Who can take part
Ages 2 and older
You may be able to join if
- ≥2.0 months of age at initiation of busulfan conditioning
- New diagnosis of typical or minimally leaky ART-SCID, as defined by the criteria below:
- Artemis deficiency with bi-allelic pathogenic or likely pathogenic mutations in DCLRE1C; AND
- CD3 count \ 50/µL and \<300/uL and with restricted T cell receptor Vb diversity; AND
- CD45 cell response to mitogens (PHA) \< 50% of the lower limit of normal range for the lab (leaky ART-SCID).
You likely can't join if
- Presence of a medically eligible HLA-matched sibling
- Evidence of HIV infection by polymerase chain reaction or p24 antigen testing.
- Unable to tolerate general anesthesia and/or marrow harvest or insertion of central venous catheter.
- Any one of liver function tests AST, ALT, gamma-glutamyl transpeptidase (GGT) \>5X the upper limit of normal for lab and/or total bilirubin \>2.0...
- Presence of any severe medical conditions making a patient unsuitable for busulfan administration
- Presence of a recognized second gene mutation that results in an autosomal dominant or recessive disorder intrinsic to hematopoietic cells and that...

- Presence of any severe medical conditions making a patient unsuitable for busulfan administration
- Presence of a recognized second gene mutation that results in an autosomal dominant or recessive disorder intrinsic to hematopoietic cells and that could be treated by an allogeneic HCT.
- Presence of a medical condition indicating that survival is predicted to be less than 4 months, such as the requirement for mechanical ventilation, severe failure of a major organ system, or evidence of a serious...
- A social situation indicating that the family may not be able to comply with protocol procedures and recommended medical care and follow-up.
- Other conditions which in the opinion of the Principal Investigator and/or co-investigators, contra-indicate the infusion of transduced cells or study participation.
