View clinical trials related to Morquio A Syndrome.
Filter by:Morquio A disease is a devastating systemic skeletal disease in which detailed progression and pathogenesis remain unknown. The proposed project aims to establish a non-invasive objective assessment that can be applicable to all ages of patients to better understand the progress of their disease and the most serious clinical problems (cervical instability and stenosis, tracheal obstruction, hyperlaxity of joints, hip dysplasia, and small lung capacity). The outcome of this project will lead to a more precise understanding of the skeletal/pulmonary compromise and defining clinical endpoints in this disease for future clinical trials of current or developing therapies.
Mucopolysaccharidoses (MPS) are multisystemic diseases with significant clinical overlap between their types, with cardiac problems being among the most commonly observed manifestations and are also among the main causes of mortality in these patients. For some of the cardiovascular manifestations, such as aortic root dilation and valve diseases, there is no effective treatment currently available. Losartan, on the other hand, has been shown to be an effective drug for dilation of the aortic root, at least in animal models. This study aims to evaluate the safety and efficacy of losartan in patients with MPS VI and other mucopolysaccharidoses.
The objectives of this program are: to characterize and describe the Mucopolysaccharidosis IV type A (MPS IVA) population as a whole, including the heterogeneity, progression, and natural history of MPS IVA; to evaluate the long-term effectiveness and safety of Vimizim®, including, but not limited to, the occurrence of serious hypersensitivity reactions, anaphylaxis, and changes in antibody status; to help the medical community with the development of recommendations for monitoring MPS IVA patients and reports on patient outcomes to optimize patient care; to collect data on other treatment paradigms, and evaluate the prevalences of their use and their effectiveness; to characterize the effects and safety of Vimizim treatment 5 years from enrollment in the Registry for patients under 5 years of age; to monitor pregnancy exposure, including maternal, neonatal, and infant outcomes; and to monitor patients who have completed the MOR-005 and MOR-007 clinical trials. These patients will be encouraged to enroll in the applicable Registry Substudy and will be monitored using the MOR-005 and MOR-007 assessment schedules, respectively.
Mucopolysaccharidosis IV, also known as MPS IV or Morquio disease, is a rare autosomal recessive genetic lysosomal storage disorder. Research thus far regarding Morquio, has primarily focused on the physical aspects of the various diseases. Less attention has been paid to the psychological toll of these diseases, whether they are direct symptoms or reactions to living with a chronic progressive disease. Prior to 2013, there was neither a cure nor treatment (other than palliative) for Morquio disease. In the latter half of 2013, ERT became available to the broader population of patients with Morquio A disease through BioMarin's Expanded Access Program. In a previous study, entitled "Psychological Concomitants of Morquio syndrome" the present investigator enrolled 20 adult subjects with Morquio into a pilot study to estimate a baseline incidence of psychological symptoms and overall quality of life. Subjects were all over the age of 18. Data from this study were published in 2015. The present study extends this research into psychological health with Morquio via a comparison of psychological issues and quality of life before and after treatment (i.e. ERT). As ERT does not cross the blood-brain barrier, it would be unlikely to improve organic psychological symptoms, but may improve any reactive psychological symptoms caused by living over time with this chronic progressive genetic disease. The present study thus seeks to follow adult patients with Morquio A disease as they begin ERT and track their psychological health every 6 months for a duration of 2 years. Adult patients with Morquio disease are invited to participate. Subjects will complete three different self-report questionnaires, the Achenbach System of Empirically Based Assessment (ASEBA) Adult Self-Report (ASR), the Short Form 36-item Health Questionnaire (SF-36), and the Brief Pain Inventory (BPI). Group aggregate data 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.
The Expanded Access Program (EAP) is an open-label, multicenter program to: 1. Provide patients who have been diagnosed with Mucopolysaccharidosis IVA (MPS IVA) access to BMN 110 until commercial product is available 2. Collect additional information on the safety and tolerability of BMN 110 administration in patients with MPS IVA Patients enrolled in the EAP will receive 2.0 mg/kg intravenous infusions of BMN 110 every week during the program.
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 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.
This open-label Phase 2 study will evaluate the safety and efficacy of weekly 2.0 mg/kg/wk infusions of BMN 110 in pediatric patients, less than 5 years of age at the time of administration of the first dose of study drug, diagnosed with MPS IVA (Morquio A Syndrome) for up to 208 weeks.
This Phase 3 extension study will evaluate the long-term efficacy and safety of BMN 110 2.0 mg/kg/week and/or BMN 110 2.0 mg/kg/every other week in patients with mucopolysaccharidosis IVA (Morquio A Syndrome).
This multicenter, open-label extension study is designed to assess long-term efficacy and safety of 2.0 milligrams (mg)/kilogram(kg)/week of BMN 110 in patients diagnosed with Mucopolysaccharidosis IVA (MPS IVA). Patients with MPS IVA, who enrolled in a prior BioMarin sponsored clinical study of BMN 110 (NCT00884949; Study Identification Number MOR-002), were eligible to enroll in this study (except patients who enrolled in NCT01275066; Study Identification Number MOR-004).
