Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients will be followed for 8 years after gene therapy. After completing participation in this study, subjects will be offered enrollment into an approved long term follow-up (LTFU) study which will enable continued follow-up for up to 15 years post-treatment (per regulatory guidelines for follow up of patients treated with ATMPs).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Treatment
Gene therapy (autologous, CD34+ cell enriched cells fraction containing HSCs, transduced with the IDUA LV encoding for the human IDUA gene and cryopreserved in cryoformulation medium)
Frozen autologous CD34+ hematopoietic stem and progenitor cells genetically modified with the lentiviral vector IDUA LV, encoding for the α-L-iduronidase cDNA, in their final formulation medium.
The drug product target dose is more or equal to 8x10\^6 CD34+ cells/Kg, with a minimum dose of 4x10\^6 CD34+ cells/Kg and a maximum dose of 35x10\^6 CD34+ cells/Kg.
The product will be injected intravenously.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Sex: Males and Females
* Age: ≥ 28 days and ≤ 11 years old
* Biochemically and molecularly proven MPS IH
* Lansky index \>80%
* Indication to hematopoietic stem cell transplant
* Lack of a non-heterozygous (for mutated IDUA) HLA-matched sibling donor or a ≥7/8 (4 digits high-resolution typing) HLA-matched cord blood donor with a cellularity ≥5 x 10\^7 Total Nucleated Cells (TNC)/Kg after 1-month search.(This criterion will not apply to patients whose country of origin does not offer unrelated donor cord blood transplantation).
* Adequate cardiac, renal, hepatic and pulmonary functions
Exclusion Criteria
* Severe, active viral, bacterial or fungal infection at eligibility evaluation
* Patients affected by neoplasia or family history of familial cancer syndromes
* Cytogenetic alterations associated with high risk of developing hematological malignancies
* History of uncontrolled seizures
