Study design details

• Main study objective:
  The objective of the registry is to collect long term safety and effectiveness outcomes for patients that have received Strimvelis™.
• Outcomes:
  Assessment of: Effectiveness: Survival, Treatments of interest, Immune reconstitution, metabolite detoxification, Vector copy number, severe infections, non-immunological manifestations, Pediatric development and PRO Safety: Reported AEs and SAEs, Laboratory blood test results, Fertility/pregnancy related outcomes, RIS analysis and replication competent retrovirus.
• Data analysis plan:
  This is an exposure registry without a comparison group and no inferential hypothesis testing will be performed. All data, including patient demographics, laboratory values, and AE/SAE rates will be summarized using descriptive statistics.
