Inclusion Criteria
  1. Provide informed consent from a competent custodial parent or guardian with legal capacity to execute a local Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved consent.

  3. Have a confirmed diagnosis of CALD as defined by abnormal VLCFA profile and cerebral lesion on brain MRI.

  4. Depending on the cohort, the subject must:

    • Be scheduled for allo-HSCT evaluation at a study site (prospective cohort only),
    • Have received an allo-HSC infusion and be consented in time to complete the Month 24 Visit on study (partial prospective/retrospective cohort only), or

NameTimeMethod
Incidence and timing of neutrophil engraftment.1-48 (± 1) months post allo-HSC infusion

Incidence of engraftment failure or allograft rejection.1-48 (± 1) months post allo-HSC infusion
Proportion of subjects who experience either ≥Grade II acute (Graft versus Host Disease) GVHD or chronic GVHD.1-48 (± 1) months post allo-HSC infusion
Number of emergency room visits.1-48 (± 1) months post allo-HSC infusion
Number and duration of in-patient hospitalization.1-48 (± 1) months post allo-HSC infusion
Secondary Outcome Measures
NameTimeMethod
MFD-free survival48 (± 2) months post allo-HSC infusion
Change from Baseline in Loes score1-48 (± 2) months post allo-HSC infusion
Change from Baseline in Neurological Function Score (NFS)1-48 (± 2) months post allo-HSC infusion
Frequency and timing of resolution of gadolinium enhancement on MRI, if applicable1-48 (± 2) months post allo-HSC infusion
Incidence of Major Functional Disabilities (MFDs).1-48 (± 2) months post allo-HSC infusion
