Gene Therapy
Infusion of autologous CD34+ cells genetically modified by the EF1αS-ADA (EFS-ADA) lentiviral vector (LV) Busulfan: Busulfan is used for non-myeloablative conditioning Polyethylene glycol-modified adenosine deaminase (PEG-ADA): PEG-ADA enzyme replacement therapy (ERT) is discontinued at Day 30 +/- 3 days from date of infusion of OTL-101.
Historical Control Group
Historical data from patients with Severe Combined Immunodeficiency Due to ADA Deficiency (ADA-SCID) who were treated with Hematopoietic Stem Cell Transplantation (HSCT): Historical data from a database of ADA-SCID patients treated with allogeneic HSCT from Great Ormond Street Hospital (GOSH) and Duke University Children's Hospital were collected as comparator group.

Population: Historical control groups/arms are not included in the analysis population for this outcome measure as these subjects did not receive gene therapy, and so measurement of VCN levels is not relevant

Vector copy number in the PB granulocyte fraction that was T cell depleted, is a surrogate for amount of engrafted genetically modified Hematopoietic stem cell (HSC) that are producing granulocytes every 3-5 days. VCN analysis was performed by Droplet Digital PCR (ddPCR) on DNA extracted from peripheral blood granulocytes.

Population: HSCT Controls With MRD arm is not included in the analysis population for this outcome measure as dAXP data was not reported between 17-30 months post-HSCT for any patients in this arm.

Decreased dAXP levels coincide with increased ADA enzyme activity, detoxification was used to demonstrate functional ADA enzyme production from the introduced ADA transgene. The threshold for detoxification was \<100 μmol/L.

Population: Historical control groups/arms are not included in the analysis population for this outcome measure as these subjects did not receive gene therapy, and so measurement of VISA is not relevant

Vector Integration Site Analysis (VISA) allowed determination of the distribution of vector integration sites in each subject's genome, as well as the relative clonal abundance. VISA was to be considered abnormal for a subject if, in 2 or more instances during the course of follow-up, a single integration site was found to represent \>30% of the total integration sites detected.

The infections of interest in this study were severe infections or opportunistic infectious episodes, defined as infections requiring hospitalization or prolonging hospitalization and/or documented infections by opportunistic pathogens. Infections that took place in the first 3 months of follow-up post treatment were excluded from calculations to avoid possible bias introduced in the data by the effects of conditioning.
