Plain-language summary
MPS IIIA, also known as Sanfilippo A, is an inherited lysosomal storage disease (LSD). MPS IIIA is caused by a deficiency in sulfamidase, one of the enzymes involved in the lysosomal degradation of the glycosaminoglycan (GAG) heparan sulfate (HS). The natural course of MPS IIIA is characterized by devastating neurodegeneration with initially mild somatic involvement. The aims of the present study is to assess the dose related safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of SOBI003, a chemically modified recombinant human (rh) Sulfamidase developed as an enzyme replacement therapy (ERT).

Inclusion criteria
✓. Informed consent obtained from the patient's legally authorized representative(s)
✓. Patients with MPS IIIA, as confirmed by both:
✓. Chronological age of ≥12 and ≤72 months (i.e., 1 to 6 years) at the time of the first SOBI003 infusion and a developmental age ≥12 months at screening as assessed by the Vineland Adaptive Behavior Scales, Second Edition (VABS-II)
✓. Medically stable patient who is expected to be able to comply with study procedures
✕. Patients is currently receiving psychotropic or other medications which in the investigator's opinion, would be likely to substantially confound test results
✕
What they're measuring
1
Safety as Measured by Adverse Events Frequencies (by Type and Severity)
Timeframe: From start of first infusion up to Week 24
. Significant non-MPS IIIA-related central nervous system (CNS) impairment or behavioral disturbances, which in the investigator's opinion, would confound the scientific integrity or interpretation of study assessments
✕. Prior administration of stem cell or gene therapy, or ERT for MPS IIIA
✕. Concurrent or prior (within 30 days of enrolment into this study) participation in a study involving invasive procedures
