Filter by: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.
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).
