Intrathecal and intravenous LV gene therapy: Direct IT and IV LV gene therapy to deliver high levels of LVs at 1-2×10\^9 multiplicity of infection/ml which carry normal ABCD1 gene
Study summary
This is a Phase I/II clinical trial of gene therapy for treating X-linked adrenoleukodystrophy using a high-safety, high-efficiency, self-inactivating lentiviral vector (LV) TYF-ABCD1 to functionally correct the defective gene. The objectives are to evaluate the safety and efficacy of the intrathecal and intravenous lentiviral gene transfer clinical protocol.

Primary outcome measure(s)
Safety evaluation of IT and IV injections of lentiviral TYF-ABCD1, determined by number of participants with treatment-related adverse events (AEs), according to scheduled assessments, vital signs, & physical examinations as assessed by CTCAE v4.0. — Minimum 1 day, maximum 1 year follow up Safety of direct IT and IV injections of lentiviral TYF-ABCD1, determined by number of participants with treatment-related adverse events (AEs), according to scheduled assessments, vital signs, \& physical examinations as assessed by CTCAE v4.0. AEs \& clinically significant abnormalities (meeting grade 3, 4, or 5 criteria according to CTCAE) will be summarized by maximum intensity \& relationship to study drug(s). Grade 1 \& 2 AEs will be summarized if related to study therapy.
Altered disease progression — Minimum 6 months, maximum 3 year follow up Altered disease progression based on biochemicaland neurological analysis.
Assess disease progression — Minimum 6 months, maximum 3 year follow up Assess disease progression based on MRI brain imaging analysis.
