Filter by:UX003-CL201 is an open-label Phase 1/2 study to assess the safety, efficacy, and dose of UX003 in MPS 7 patients via intravenous (IV) administration every other week (QOW) for 36 weeks with up to an additional 36 weeks from the optional continuation period. Up to 5 participants, who are between 5 and 30 years of age inclusive, will be enrolled and treated with UX003. The initial 12-week treatment period will be followed by a 24-week forced dose titration period to assess the optimal dose. Participants who complete both the initial treatment and forced dose titration periods will continue treatment in a 36- week continuation period.
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.
Mucopolysaccharidosis IV, also known as MPS IV or Morquio disease, is a rare autosomal recessive genetic lysosomal storage disorder. Research thus far regarding lysosomal storage diseases (LSDs) in general, including Morquio, has primarily focused on exploring the causes of and finding a treatment for the physical aspects of the various diseases. Less attention has been paid to the psychological or emotional toll of these diseases, whether they are direct symptoms of the diseases themselves or reactions to living with a chronic progressive disease. It is well established in the health psychology literature, however, that the interaction between our physical health and our psychological health is bidirectional; that is, just as our physical health affects us emotionally (e.g. chronic pain can contribute to depression), so can our psychological health affect us physically (e.g. anxiety can contribute to feelings of chest pain). It is thus critically important to pay attention to the emotional and psychological symptoms associated with all lysosomal storage diseases, including Morquio, and expand our treatment standard of care to include mental health treatment, if necessary. The first step in understanding and treating psychological conditions in Morquio disease is determining the natural occurrence of psychological symptoms in this population in comparison with non-medical populations. As little has been done in this regard, a pilot study documenting the occurrence rate of psychological issues and overall quality of life in patients with Morquio is the first item in order and will be the focus of this study. Approximately 20 patients with Morquio disease will be invited to participate, recruited through Emory's Lysosomal Storage Disease Center, as well as through attendance at Morquio support groups and relevant regional, national and/or international meetings. Once consented, patients will be asked to complete three different self-report questionnaires, including the Achenbach System of Empirically Based Assessment (ASEBA) Adult Self-Report (ASR) or Older Adult Self-Report (OASR) questionnaire, the Short Form 36-item Health Questionnaire (SF-36), and the Brief Pain Inventory (BPI). Group aggregate data only will be reported; individual questionnaire content and results will be held confidential, except as in accordance with Georgia law relating to reporting of child or elder abuse, suicidal and/or homicidal intent. Completion of these questionnaires will complete subjects' participation in this pilot study.
The purpose of this study is to find out more about some of the unusual chemicals (called oligosaccharides) that can occur naturally as a result of processes in the body. Researchers want to look at how these chemicals change with time and how they change between different patients with MPSIVA. These unusual chemicals were recently discovered in the urine from patients with MPSIVA. The investigators would like to study these chemicals before a specific enzyme replacement therapy is used. If the investigators understand how these chemicals change, the investigators may be able to use them to monitor this condition in the near future as well as help doctors know whether certain therapies work well in their patients.
BACKGROUND/OBJECTIVE: Quantitative urine screening for mucopolysaccharides (MPS) has been the primary method for detecting mucopolysaccharidoses in children. This method may not be sufficiently sensitive and may miss some patients with arylsulfatase B (ARSB) deficiency. Investigators propose to identify patients retrospectively and prospectively who carry a diagnosis of spondyloepiphyseal dysplasia, multiple epiphyseal dysplasia, bilateral proximal femoral epiphyseal dysplasia, or bilateral Legg-Calve-Perthes. For these patients, investigators will perform enzyme testing on a blood sample which will identify MPS VI or IVA. Patients who have an earlier diagnosis of MPS are likely to have better health outcomes with medical management. Therefore, it is important to determine effective diagnostic methods. Investigators believe that bilateral hip involvement should alert the clinician to the possibility of MPS VI and further examination. The purpose of this study is to test the hypothesis that the correct diagnoses of two MPS storage disorders are delayed in patients with bilateral proximal femoral epiphyseal dysplasia and normal quantitative urine MPS studies.
The primary objective of this study is to evaluate the effect of 2.0 mg/kg/week BMN 110 in a patient population that has limited ambulation, in a period of up to 144 weeks.
The aim of the present study is to compare intraocular pressure (IOP) values assessed with Ocular Response Analyzer to the classical gold standard of IOP measurement, to Goldmann applanation tonometry by mucopolysacchyridosis-, Fabry-patients and healthy controls. We want to investigate biomechanical characteristics of the cornea and their influence on the IOP-measurements.
This study is being done to learn how many children and young adults who come to pediatric rheumatology clinics may have mucopolysaccharidosis (MPS). The study tests for 4 of the types of MPS: I, II, IVA, and VI. This can help researchers decide whether to create a screening program for MPS at pediatric rheumatology clinics. This study is being done in rheumatology clinics because the first symptoms of MPS are often joint problems such as stiff joints, and rheumatologists may be the first doctors that a patient with MPS visits. The study will also evaluate the utility of dried blood spot testing for MPS.
The primary objective of this study was to evaluate the safety of a 2.0 mg/kg/week and a 4.0 mg/kg/week of BMN 110 in patients with Morquio A syndrome for up to 196 weeks. Secondary objectives were to investigate the effect of the two doses on exercise capacity for up to 196 weeks. In addition, the pharmacokinetic (PK) parameters of both doses of BMN 110 was assessed.
Study IDS116406 will be a non-interventional, phlebotomy study in Hunter Syndrome patients who are currently being treated with idursulfase, an enzyme replacement therapy, and in at least a single patient who is naïve to treatment, if possible to recruit. All patients enrolled into the study will have a single blood draw for the analysis of antibodies induced by this enzyme replacement therapy (idursulfase). Patient samples with positive responses to antibodies induced by idursulfase will be used to further evaluate whether the antibodies induced by idursulfase bind to GSK2788723 molecules in vitro and if these antibodies neutralize the bioactivity of GSK2788723 in vitro. Each subject will have a screening visit, which may occur at their regularly scheduled out-patient visit. If the patient consents to participate in the study, a blood sample (total volume of approximately 3mL) for immunogenicity analysis will be drawn before their current treatment infusion
