What this trial measures

  • Overall Survival (OS) at Month 6 Post HCTMonth 6 Post HCT

    Assess the overall survival (OS) for participants after hematopoietic stem cell transplantation (HCT) for treatment of Severe Combined Immunodeficiency (SCID). The time to this event is the time from HCT to death or last follow-up (whichever occurs first). All participants will be followed for a minimum of 6 months from HCT. Overall survival will be estimated at 6 months.

  • Overall Survival (OS) at Year 2 Post HCTYear 2 Post HCT

    Assess the overall survival (OS) for participants after hematopoietic stem cell transplantation (HCT) for treatment of Severe Combined Immunodeficiency (SCID). The time to this event is the time from HCT to death or last follow-up (whichever occurs first). All participants will be followed for a minimum of 6 months from HCT. Overall survival will be estimated at 2 years.

  • Overall Survival (OS) at Year 5 Post HCTYear 5 Post HCT

    Assess the overall survival (OS) for participants after hematopoietic stem cell transplantation (HCT) for treatment of Severe Combined Immunodeficiency (SCID). The time to this event is the time from HCT to death or last follow-up (whichever occurs first). All participants will be followed for a minimum of 6 months from HCT. Overall survival will be estimated at 5 years.

  • Overall Survival (OS) at Year 8 Post HCTYear 8 Post HCT

    Assess the overall survival (OS) for participants after hematopoietic stem cell transplantation (HCT) for treatment of Severe Combined Immunodeficiency (SCID). The time to this event is the time from HCT to death or last follow-up (whichever occurs first). All participants will be followed for a minimum of 6 months from HCT. Overall survival will be estimated at 8 years.
