Halted Human Pharmacology (Phase I)- Other Severe combined immunodeficiency based on genetic defect in the Recombinase Activating Gene 1 (RAG1)

Phase I/II clinical trial of autologous hematopoietic stem cell gene therapy in rag1-deficient severe combined immunodeficiency

EU CTIS ID: 2023-510204-50-00

What this study is testing

To evaluate the effect of RAG1 gene therapy on overall survival To evaluate the efficacy of RAG1 gene therapy in achieving reconstitution of the T and B cell immune system in patients with RAG1-SCID at 6 months To evaluate the safety and tolerability of the RAG1 gene therapy product, including identification of short- and long-term adverse events

Who can take part

You may be able to join if

  • RAG1-deficient SCID as confirmed by genetic analysis
  • Peripheral blood T cells < 300/μL and/or naïve T cells < 1/μL
  • Age < 2 years
  • Age at least 8 weeks by the time of busulfan and fludarabine administration
  • Lack of an available HLA-matched donor (HLA-identical sibling or 10/10 (A, B, C, DR, DQ) allele-matched (un)related donor)
  • Signed informed consent (parental or guardian)

You likely can't join if

  • Omenn syndrome
  • Previous allogeneic HSCT
  • Significant organ dysfunction/co-morbidity (including but not limited to): Mechanical ventilation, Shortening fraction on echocardiogram <25%, Renal failure defined as dialysis dependence, uncontrolled seizure disorder.)
  • Any other condition that the investigator considers is a contraindication to collection and/or infusion of transduced cells for that individual or indicate patient's inability to follow the protocol, for example contraindication f to busulfan, major congenital abnormalities, ineligible to receive anaesthesia, or documented refusal or inability of the family to return for scheduled visits.
  • Human immunodeficiency virus (HIV) infection or Human T-cell Leukemia Virus (HTLV) infection.
