Outcome Measures

Primary Outcomes (4)

  • The short-term safety and tolerability after hematopoietic stem cell transplanation

    The absence of engraftment failure or delayed hematopoietic reconstitution (prolonged aplasia), defined as Absolute Neutrophil Count (ANC)\<500/μl with no evidence of Bone Marrow recovery, requiring cellular back-up administration.

    2 months

  • Incidence of Treatment-Emergent Adverse Events(For MLD)

    It will be evaluated on the basis of adverse events reporting and monitoring of the systemic reactions to cell infusion (fever, tachycardia, nausea and vomiting, joint pain, skin rash).

    72 hours

  • Incidence of Treatment-Emergent Adverse Events(For ALD)

    It will be evaluated on the basis of adverse events reporting and monitoring of the systemic reactions to cell infusion (fever, tachycardia, nausea and vomiting, joint pain, skin rash).

    72 hours

  • The long-term safety safety after hematopoietic stem cell transplanation

    The absence of adverse affects in the long-term follow-up of HSCGT-treated patients, like hematopoietic system disease.

    up to 8 years

Secondary Outcomes (6)

  • ARSA activity for MLD

    up to 8 years

  • VLCFA level for ALD

    up to 8 years

  • Magnetic Resonance imaging (MRI) score

    up to 8 years

  • Functional independence measure (FIM) score

    up to 8 years

  • Vector copy number (VCN)

    up to 8 years

  • +1 more secondary outcomes

Study Arms (1)

transduced CD34+ hematopoietic stem cell

EXPERIMENTAL

Transplantation of autologous CD34+ hematopoietic stem cells transduced with ARSA/ABCD1 encoding lentiviral vector. Dosage: 2x10\^6/Kg (Minimum)to 20x10\^6/Kg (Maximum) transduced CD34+ cells at bedside for infusion

Genetic: transduced CD34+ hematopoietic stem cell

Interventions

Autologous hematopoietic stem cells (HSCs) collected from the mobilized peripheral blood and transduced ex vivo with a Lentiviral vector encoding the human ARSA(for MLD)/ABCD1(for ALD) cDNA(complementary DNA). Dose: ≥ 2x10\^6 transduced CD34+ cells/Kg (maximum 20x10\^6) at bedside for infusion.

transduced CD34+ hematopoietic stem cell

Eligibility Criteria

Age1 Year - 16 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Confirmed diagnosis as MLD by ARSA genetic diagnosis, MRI(Magnetic Resonance Imaging)and low ARSA A activity (below 20% of normal level);
  • The patient' symptoms and lesions have not been developed to the end stage of MLD.
  • age \< 16.0 years at symptom onset
  • Confirmed diagnosis as ALD by ABCD1 genetic diagnosis, abnormal MRI imaging, abnormal high level of very long chain fatty acid (VLCFA) and adrenocorticotropic hormone (ACTH);
  • The patient' symptoms and lesions have not been developed to the end stage of ALD.
  • age \< 16.0 years at symptom onset

You may not qualify if:

  • At a pre-symptomatic stage of of MLD;
  • ARSA activity \>50% compared to healthy individuals;
  • End stage of MLD;
  • Other complications, ie. Cancer;
  • human immunodeficiency virus(HIV) RNA and/or hepatitis C virus RNA and/or hepatitis B virus DNA positive patients;
  • Patients who underwent allogenic hematopoietic stem cell transplantation with evidence of residual cells of donor origin.
  • Serious organ dysfunction;
  • were enrolled in other clinical trials in the 6 months prior to screening;
  • had any other concern that hampered the compliance or safety as judged by the investigator;
  • Adult
  • No evidence of brain lesions;
  • Normal level of VLCFAs in blood;
  • End stage of ALD;
  • Other complications, ie. Cancer;
  • human immunodeficiency virus(HIV) RNA and/or hepatitis C virus RNA and/or hepatitis B virus DNA positive patients;
  • +5 more criteria
