Extension of Study HGT-SAN-055 Evaluating Administration of rhHNS in Patients With Sanfilippo Syndrome...
Sanfilippo SyndromeSanfilippo syndrome, or Mucopolysaccharidosis (MPS) III, is a rare lysosomal storage disease (LSD) caused by loss in activity of 1 of 9 enzymes necessary for degradation of the glycosaminoglycan (GAG) heparan sulfate (HS) in lysosomes. MPS IIIA results from deficiency of the enzyme heparan N-sulfatase (sulfamidase). In the absence of this enzyme, intermediates of the HS degradation process accumulate in the lysosomes of neurons and glial cells, with lesser accumulation outside the brain. MPS IIIA symptoms arise on average at 7 months of age, with the average age of diagnosis at 4.5 years for the majority of patients. Patients present a wide spectrum and severity of clinical symptoms. The central nervous system (CNS) is the most severely affected organ system in patients with MPS IIIA, evidenced by deficits in language development, motor skills, and intellectual development. In addition, there are abnormal behaviors including but not limited to aggression and excess motor activity/hyperactivity that contribute to disturbances in sleep.Overall, individuals with MPS IIIA have a marked developmental delay and significantly reduced lifespan to 15 years of age on average. The purpose of this study is to collect long term safety and tolerability data in patients with MPS IIIA who previously received rhHNS in study HGT-SAN-055 (NCT01155778).

Mucopolysaccharidosis IIIType B (MPS IIIB)1 moreThis study evaluated the safety and tolerability of intravenous (IV) administration of SBC-103 in previously studied, SBC-103 treatment naïve patients with mucopolysaccharidosis III, type B (MPS IIIB, Sanfilippo B) who participated in the NGLU-CL01 study. The NGLU-CL01 study was a non-interventional study that evaluated structural brain abnormalities and blood brain barrier (BBB) integrity by magnetic resonance imaging (MRI) and cerebrospinal fluid/serum albumin index.
An Extension Study to Determine Safety and Efficacy for Pediatric Patients With MPS Type IIIA Disease...
Sanfilippo SyndromeMucopolysaccharidosis (MPS)This extension study will allow participants to continue receiving treatment with HGT-1410 and to initiate treatment in patients who received no-treatment in Study HGT-SAN-093, and will evaluate the long-term safety and efficacy of the study drug.
A Treatment Study of Mucopolysaccharidosis Type IIIB
MPS III BMucopolysaccharidosis Type IIIBThe study's primary objectives are to evaluate the safety and tolerability of AX 250 administered to subjects with MPS IIIB via an ICV reservoir and catheter and to evaluate the impact of AX 250 on cognitive function in patients with MPS IIIB as assessed by the Development Quotient.

Mucopolysaccharidosis (MPS)Sanfilippo syndrome, or Mucopolysaccharidosis (MPS) III, is a rare lysosomal storage disease (LSD) caused by loss in activity of 1 of 4 enzymes necessary for degradation of the glycosaminoglycan (GAG) heparan sulfate (HS) in lysosomes. MPS IIIA results from deficiency of the enzyme heparan N-sulfatase (sulfamidase). MPS IIIA symptoms arise on average at 7 months of age, with the average age of diagnosis at 4.5 years for the majority of patients. The central nervous system (CNS) is the most severely affected organ system in patients with MPS IIIA, evidenced by deficits in language development, motor skills, and intellectual development. In addition, there are abnormal behaviors including but not limited to aggression and excess motor activity/hyperactivity that contribute to disturbances in sleep.Overall, individuals with MPS IIIA have a marked developmental delay and significantly reduced lifespan of 15 years of age on average. The purpose of this study is to determine the safety and tolerability of rhHNS via ascending doses administered via an a surgically implanted intrathecal drug delivery device (IDDD) intrathecal (IT) route once monthly (or every two weeks) for 6 months in patients with MPS IIIA.
Intracerebral Gene Therapy for Sanfilippo Type A Syndrome
Mucopolysaccharidosis Type III ASanfilippo Disease Type AThe clinical trial P1-SAF-301 is an open-label, single arm, monocentric, phase I/II clinical study evaluating the tolerance and the safety of intracerebral administration of adeno-associated viral vector serotype 10 carrying the human SGSH and SUMF1 cDNAs for the treatment of Sanfilippo type A syndrome The treatment plan consists on a direct injection of the investigational medicinal product SAF-301 to both sides of the brain through 6 image-guided tracks, with 2 deposits per track, in a single neurosurgical session. The primary objective is to assess the tolerance and the safety associated to the proposed treatment through a one-year follow up. The secondary objective is to collect data to define exploratory tests that could become evaluation criteria for further clinical phase III efficacy studies. Four patients will be included in the clinical trial and will be followed during one year. The enrollment and the follow-up of the patients will take place at Bicêtre Hospital. The Neurosurgery will be performed at Necker-Enfants Malades Hospital. Safety will be evaluating on clinical, radiological and biological parameters.
A Study to Assess the Safety and Tolerability of SOBI003 in Pediatric MPS IIIA Patients
Sanfilippo Syndrome Type A (MPS IIIA)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).
