Mucopolysaccharidosis clinical trials at UC Health
9 in progress, 4 open to eligible people

  • A Prospective Natural History Study of Mucopolysaccharidosis Type IIIB (MPS IIIB)

    open to eligible people ages up to 18 years

    This is a natural history study for children up to 18 years of age who have been diagnosed with Mucopolysaccharidosis Type IIIB (MPS IIIB, also known as Sanfilippo Syndrome Type B). Mucopolysaccharidosis type IIIB is a severe neurodegenerative disorder. The information gathered from this trial may help inform the design and interpretation of subsequent interventional studies. No clinical intervention or study drug is provided by BioMarin in this study.

  • Mucopolysaccharidosis (MPS) VI Clinical Surveillance Program (CSP)

    open to all eligible people

    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.

  • RGX-121 Gene Therapy in Patients With MPS II (Hunter Syndrome)

    open to eligible males ages 4 months to 5 years

    RGX-121 is a gene therapy which is intended to deliver a functional copy of the iduronate-2-sulfatase (IDS) gene to the central nervous system. This study is a safety and dose ranging study to determine whether RGX-121 is safe and tolerated by patients with MPS II.

  • Study to Evaluate the Safety and Efficacy of Adalimumab in MPS I and II

    open to eligible people ages 5 years and up

    Randomized, double-blind, placebo-controlled, parallel-group, single-center study followed by open-label phase, to evaluate the effects of adalimumab compared to placebo on the change from baseline in joint and skeletal disease in children and adults with mucopolysaccharidosis (MPS) I or II.

  • A Study of Mucopolysaccharidosis Type IIIB (MPS IIIB)

    Sorry, in progress, not accepting new patients

    Mucopolysaccharidosis type IIIB (MPS IIIB, also known as Sanfilippo Syndrome Type B) is a severe neurodegenerative disorder. The purpose of this study is to learn more about the health problems in patients with MPS IIIB and how to measure these problems over time. It will particularly look at how the disease develops in young children. This is an observational study, so no experimental drug will be given. The results from this study will help us design future studies to measure whether these health problems get better when we give experimental drug for MPS IIIB.

  • A Treatment Extension Study of Mucopolysaccharidosis Type IIIB

    Sorry, accepting new patients by invitation only

    The primary objectives of this study are to evaluate the long-term safety and tolerability of BMN 250 administered to subjects with MPS IIIB by an implanted ICV reservoir and catheter and to evaluate the impact of long-term BMN 250 treatment on cognitive function in patients with MPS IIIB as assessed by developmental quotient (DQ).

  • Ascending Dose Study of Genome Editing by the Zinc Finger Nuclease (ZFN) Therapeutic SB-913 in Subjects With MPS II

    Sorry, in progress, not accepting new patients

    The purpose of the study is to evaluate the safety, tolerability and effect on leukocyte and plasma Iduronate 2-Sulfatase (IDS) enzyme activity of ascending doses of SB-913. SB-913 is an intravenously delivered Zinc Finger Nuclease (ZFN) Therapeutic for genome editing. It inserts a correct copy of the IDS gene into the Albumin locus in hepatocytes with the goal of lifelong therapeutic production of the IDS enzyme.

  • Extension Study of Intrathecal Enzyme Replacement for Cognitive Decline in MPS I

    Sorry, accepting new patients by invitation only

    This is a five-year extension study of the pilot study, "Intrathecal Enzyme Replacement for Cognitive Decline in MPS I". Participants must have completed the pilot study to participate in this study.

  • Open-label Study of Anakinra in MPS III

    Sorry, not yet accepting patients

    Sanfilippo syndrome, or mucopolysaccharidosis type III (MPS III), is a disorder of metabolism, associated with insufficient production of a lysosomal enzyme needed for normal cell function. As a consequence of the cellular dysfunction, patients with this disorder develop progressive, irreversible neurodegeneration. Sadly, to date no evidence-based treatments are available. Inflammation has been connected with disease pathogenesis in the MPS disorders. Therapies aimed at decreasing inflammation are currently being studied in many MPS disorders and benefits in both brain and other parts of the body have been reported.Decreasing interleukin-1 (IL-1) in an animal model of MPS III showed benefits in brain disease and behavior. Thus, we think that anakinra (Kineret), which decreases IL-1 levels in the body, will improve behavioral and other problems in children with MPS III. Anakinra is approved by the FDA for treatment of rheumatoid arthritis (RA) and neonatal-onset multisystem inflammatory disease (NOMID). It is not approved for any MPS disorder. The design of this study is an open-label, single center, pilot study of 20 participants with MPS III. There will be an initial screening visit, followed by an 8-week observational period, then a 36-week treatment period, and finally another 8-week observational period to determine any effects of withdrawal from the treatment. During visits the participants will undergo a medical history, a physical examination, and anthropometric measurements. Blood, urine, and stool will be collected for biomarker levels and safety laboratory studies. Questionnaires will be completed with questions related to behavior, stooling, sleep, and activities of daily living. Seizure and movement disorders will be monitored as well. The most common risks of receiving anakinra, based on RA and NOMID experience, include local injection site reactions, headache, nausea, vomiting, arthralgia, and flu-like symptoms. The most serious potential risk is a serious infection and neutropenia. However, because so few people with MPS have been treated with anakinra, all the risks related to MPS patients receiving anakinra are not currently known. Additional risks related to taking part in the study include some pain, bruising, and/or bleeding due to blood draws/peripheral IV placement, and discomfort with completing some of the questionnaires. The expected potential direct benefits include, but are not limited to, improved behavior, sleep, stooling, communication, mood, and gait; as well as decreased seizure frequency, disordered movement and fatigue. However, there is no guarantee that participants will get any benefit from being in this study.
