Summary

This trial is evaluating a gene therapy to treat adrenomyeloneuropathy, a hereditary nervous system disorder. Patients will receive a single dose of the treatment or a fake treatment, and be closely monitored for safety and efficacy for 2 years.

Who is the study for?
Adults aged 18-65 with adrenomyeloneuropathy (AMN), able to walk, diagnosed with X-linked adrenoleukodystrophy (ALD) confirmed by genetic testing and high VLCFA levels. Not eligible if they have unstable adrenal function, prior gene therapy, MRI or anesthesia contraindications, diabetes/high blood sugar, inflammatory brain disease history, or over 15 years since myeloneuropathy onset.
What is being tested?
The trial is testing SBT101 gene therapy for AMN via a one-time spinal injection compared to an imitation procedure. It's a blind study where patients are monitored for safety and effectiveness over two years; those on SBT101 continue follow-up for three more years.
What are the potential side effects?
Potential side effects aren't specified but may include reactions related to the intrathecal route of administration such as headache or back pain, immune responses to the viral vector or inserted gene product, and typical risks associated with long-term monitoring like infection.
