A Study to Evaluate Administration of SBT101 Gene Therapy in Adult Patients With Adrenomyeloneuropathy (AMN)

Description

This is a Phase 1/2 randomized, blinded, dose-escalation study to evaluate the safety and efficacy of intrathecal (IT) administration of SBT101, a recombinant adeno-associated virus serotype 9 (AAV9) containing a functional copy of the human adenosine triphosphate (ATP)-binding cassette transporter subfamily D member 1 (ABCD1; hABCD1) gene, in adult patients with adrenomyeloneuropathy (AMN) aged 18-65 years. Patients will receive a single dose of SBT101 via IT route (or an imitation procedure) and will be followed for safety and efficacy for 2 years. Patients receiving SBT101 will be followed for an additional 3 years (5 total) for Safety. Patients receiving an imitation procedure will be offered the opportunity to receive SBT101 after 2 years, as data indicate.

Conditions

AMN, AMN Gene Mutation, X-ALD

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Diagnosed with X-linked adrenoleukodystrophy (ALD), including proven mutation in the ABCD1 gene through confirmatory genetic testing, and supported by elevated circulating VLCFA levels.
  • 2. Clinical evidence of spinal cord involvement but still able to ambulate independently
  • 1. Evidence of or past diagnosis of inflammatory cerebral disease.
  • 2. 15 years or more have elapsed since the initial onset of myeloneuropathy manifestations such as walking or running difficulties, bladder dysfunction, increased muscular tone, spasticity, weakness, balance problems, etc.
  • 3. Contraindications for MRI procedure and/or contrast materials.
  • 4. Contraindication to steroids, sirolimus, tacrolimus, and/or anesthetic medications.
  • 5. Unstable adrenal function (e.g., untreated or inappropriately treated adrenal insufficiency).
  • 6. History of diabetes or abnormal fasting plasma glucose (≥126 mg/dL) or hemoglobin A1C ≥6.5%.
  • 7. Patients who have received a gene therapy.
