Intrathecal and Intravenous Lentiviral Gene Therapy for X-linked Adrenoleukodystrophy (X-ALD)

Not applicable Interventional Shenzhen Geno-Immune Medical Institute · NCT03727555

This study is testing a new gene therapy for X-linked adrenoleukodystrophy to see if it can help improve symptoms and slow down the disease in patients with different stages of the condition.

What this trial studies

This clinical trial evaluates the safety and efficacy of a novel gene therapy approach for treating X-linked adrenoleukodystrophy (X-ALD) using a self-inactivating lentiviral vector to correct the defective ABCD1 gene. The therapy involves both intrathecal and intravenous injections to directly address the genetic defect associated with this severe neurological disorder. The study aims to include patients with varying stages of the disease, including those who already exhibit symptoms, thereby expanding treatment opportunities beyond traditional hematopoietic stem cell transplantation. The trial will assess the impact of this innovative approach on neurological function and disease progression.

Who should consider this trial

Good fit: Ideal candidates for this study are X-ALD patients aged 1 year and older who have a confirmed diagnosis and are willing to participate in the trial.

Not a fit: Patients who are HIV positive, have stabilized their condition through other treatments, or have severe infections or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for patients with X-ALD, potentially improving their neurological function and quality of life.

How similar studies have performed: While gene therapy approaches for genetic disorders are being explored, this specific application for X-ALD using a lentiviral vector is relatively novel and has not been extensively tested in prior studies.
