Active; Recruiting

Is my child eligible to participate in the study?

Take a brief eligibility survey. Key criteria for eligible patients include the following, but a full list of inclusion and exclusion criteria are available here.

  • Diagnosis of MPS IIIA
  • Age 6 months to 2 years or children older than 2 years with a minimum cognitive Developmental Quotient (DQ) of 60 or above

What will be required of patients and their families?

  • Up to two screening visits.
  • A treatment visit, once eligibility is confirmed. Patients will be admitted to the hospital for gene transfer and will stay for approximately 48 hours for observation.
  • Patients and their caregiver(s) will be required to stay near the clinical site for 30 days after gene therapy is administered.
  • After gene transfer, a total of nine follow up visits will take place at the clinical site, with the last visit occurring 24 months after gene transfer.
  • Home visits for collection of blood in between the follow-up visits to the clinical site.
  • Additional visits may be required for eligible patients receiving long-term follow-up care.
  • Frequently Asked Questions.

About the Study

MPS IIIA, or Sanfilippo syndrome type A, is caused by a build-up of toxic sugars called glycosaminoglycans (GAGs) because of a mutation in the gene encoding the SGSH enzyme. The study involves a one-time intravenous administration of ABO-102 using an adeno-associated virus vector 9 (AAV9) to deliver a normal copy of the SGSH gene. The delivery of the normal SGSH gene may allow cells to produce the SGSH enzyme responsible for breaking down GAGs. After treatment, patients are followed for 24 months to assess safety and efficacy.
