Active clinical trials for "Mucopolysaccharidoses"

MPS IIIA is predominantly a central nervous system disease causing cognitive disability, progressive loss of acquired skills, behavioral and sleep disturbance. LYS-SAF302 is a gene therapy which is intended to deliver a functional copy of the SGSH gene to the brain. This is a phase 2-3 study to assess the efficacy in improving or stabilizing the neurodevelopmental state of MPS IIIA patients.

This is a multicenter, non-interventional, long-term follow-up (LTFU) study in participants who have been treated with ABO-101 in a prior trial. Eligible participants will undergo clinical evaluations at prespecified intervals for 3 years from the last visit in the prior clinical trial (up to 5 years post-treatment).

This study evaluates the efficacy and safety of three doses of GC1111 in patients with Hunter Syndrome. Participants will be randomized to one of three doses of GC1111 or comparator.

The objectives of this study are to describe the clinical and biochemical characteristics and course of disease progression in participants with Mucopolysaccharidosis type IIIB (MPS IIIB)

The purpose of this study is to evaluate the efficacy and side effects of donor hematopoietic cells using chemotherapy regimen without total-body irradiation in children undergoing a hematopoietic stem cell transplant for Mucopolysaccharidosis. The blood stem cells will be derived from either related donor or unrelated umbilical cord blood or haploidentical donor.

This is a standard of care treatment guideline for patients with the diagnosis of mucopolysaccharidosis type IH (MPS I, Hurler syndrome) who are being considered as candidates for first hematopoietic stem cell transplantation (HSCT) according to a University of Minnesota myeloablative HSCT protocol.

Hunter syndrome (Mucopolysaccharidosis II, [MPS II]) is a rare, genetically linked lysosomal storage disease (LSD) caused by deficiency of the enzyme, iduronate-2-sulfatase (I2S). Most MPS II patients will present with some degree of neurodevelopmental involvement, ranging from severe cognitive impairment and behavioral problems to mildly impaired cognition. This is an observational study; no investigational treatment will be administered. The primary objective of this study is to evaluate the neurodevelopmental status of pediatric patients with MPS II over time and to gain information to guide future treatment studies in this patient population.

The objectives of this program are: to further characterize the natural progression of MPS VI disease; to generate and disseminate information on the care and management of MPS VI patients to clinical and medical professionals; to provide a resource to physicians and patients by providing information for optimizing patient care based on aggregate data; to characterize the clinical response to long-term Naglazyme® (galsulfase) treatment; to further characterize the long-term safety of Naglazyme® treatment.

Evaluate the clinical progression in patients with MPS IIIA who are untreated with any investigational product and to obtain standardized assessments: neurocognitive, behavioral, sleep-wake habits and effect of MPS IIIA on the quality of life of patients and their families.

Neuroinflammation and oxidative stress have been shown to be present in persons with mucopolysaccharidosis type I (MPS I), but their effect on disease severity and disease progression is unknown. The investigator intends to employ brain magnetic resonance spectroscopy (MRS), a non-invasive technique, along with analysis of neuroinflammation and oxidative stress biomarkers in the blood, to measure and determine the level of oxidative stress and neuroinflammation, and their impact on clinical variability in MPS I patients.
