E.3 | Principal inclusion criteria |
Patient with a RS-SCID caused by mutation of the Artemis gene and a clinical diagnosis of SCID documented in the medical record - Absence of an HLA genoidentical donor - Age ≤ 1 year - The patient can be treated by gene therapy without delay in case of life threatening infections compromising the short-term prognosis. Active life threatening infections are defined as: viral respiratory infection, CMV infection, adenovirus infection, disseminated BCGitis or other infections grade ≥ 4 according to CTCAE scale . - Parental, guardian's patient signed informed consent |

E.5 End points |
E.5.1 | Primary end point(s) |
(repeat as necessary)26 English Safety of ARTEGENE drug product, is assessed by: • Incidence of transplant related mortality up to 100 days post treatment • Frequency and severity of clinical AEs and laboratory parameters throughout the whole period of the research • Incidence of RCL measured at 3 months The efficacy of successful transduction of CD34+ by the vector and the injection of autologous gene-modified hematopoietic stem cells is evaluated by the assessment of T and B cells reconstitution in Artemis deficient patients after transplantation. |
L'innocuité du médicament ARTEGENE est évaluée par: • Incidence de la mortalité liée à la greffe jusqu'à 100 jours après le traitement • Fréquence et gravité des EI cliniques et des paramètres de laboratoire pendant toute la durée de la recherche • Incidence de RCL mesurée à 3 mois L'efficacité d'une transduction réussie de CD34 + par le vecteur et l'injection de cellules souches hématopoïétiques génétiquement modifiées autologues est évaluée par l'évaluation de la reconstitution des cellules T et B chez des patients déficients en Artemis après transplantation.
