Filter by:This Phase 3 study will evaluate the efficacy and safety of 2.0 mg/kg/week BMN 110 and 2.0 mg/kg/every other week BMN 110 in patients with mucopolysaccharidosis IVA (Morquio A Syndrome). There is currently no standard accepted treatment for MPS IVA other than supportive care. Enzyme replacement therapy (ERT) may be a potential new treatment option for MPS IVA patients. BMN 110 is administered to MPS IVA patients by IV infusion, allowing cellular uptake by the mannose-6-phosphate receptor and transportation to the lysosomes. This enzyme uptake into the lysosomes is hypothesized to promote increased catabolism of keratan sulfate (KS) in tissue macrophages, hyaline cartilage, other connective tissues, and heart valve, and reduce the progressive accumulation of KS which is responsible for the clinical manifestations of the disorders.
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).
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.
Sanfilippo syndrome, or Mucopolysaccharidosis (MPS) III, is a rare lysosomal storage disease (LSD) caused by loss in activity of 1 of 4 enzymes necessary for degradation of the glycosaminoglycan (GAG) heparan sulfate (HS) in lysosomes. MPS IIIA results from deficiency of the enzyme heparan N-sulfatase (sulfamidase). MPS IIIA symptoms arise on average at 7 months of age, with the average age of diagnosis at 4.5 years for the majority of patients. The central nervous system (CNS) is the most severely affected organ system in patients with MPS IIIA, evidenced by deficits in language development, motor skills, and intellectual development. In addition, there are abnormal behaviors including but not limited to aggression and excess motor activity/hyperactivity that contribute to disturbances in sleep.Overall, individuals with MPS IIIA have a marked developmental delay and significantly reduced lifespan of 15 years of age on average. The purpose of this study is to determine the safety and tolerability of rhHNS via ascending doses administered via an a surgically implanted intrathecal drug delivery device (IDDD) intrathecal (IT) route once monthly (or every two weeks) for 6 months in patients with MPS IIIA.
Rationale: Chemotherapy administration before a donor stem cell transplant is necessary to stop the patient's immune system from rejecting the donor's stem cells. When healthy stem cells from a donor are infused into the patient, the donor white blood cells can provide the missing enzyme that causes the metabolic disease. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving a monoclonal antibody, alemtuzumab, before transplant and cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening. This may be an effective treatment for inherited metabolic disorders. Purpose: The design of this study is to achieve donor cell engraftment in patients with standard-risk inherited metabolic diseases with limited peri-transplant morbidity and mortality. This will be achieved through the administration of the chemotherapy regimen described. The intention is to follow transplanted patient for years after transplant monitoring them for complications of their disease and assisting families with a multifaceted interdisciplinary approach.
This study is being conducted to demonstrate the safety and clinical efficacy of Aldurazyme treatment in MPS I patients
This multicenter, open-label study is designed to assess safety, dose-response using pharmacokinetic (PK) and pharmacodynamic (PD) measures, and clinical efficacy of BMN 110 in subjects between 5 and 18 years of age, diagnosed with Mucopolysaccharidosis IVA (MPS IVA).
This is a 24-month study of the use of laronidase administered into the spinal fluid to treat cognitive decline in mucopolysaccharidosis I (MPS I). MPS I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Laronidase is the manufactured form of the enzyme alpha-l-iduronidase. MPS I is a heterogeneous disease with several clinical phenotypes ranging from the most severe, Hurler syndrome, to the attenuated forms, Hurler-Scheie and Scheie. Although patients with milder forms of MPS I may not have grossly observable problems with cognition, these patients do have learning difficulties that are apparent in school and with neuropsychological testing. The goal of this study is to evaluate whether intrathecal recombinant human alpha-l-iduronidase (rhIDU) injections can stabilize or improve cognitive decline in individuals with MPS I.
This multicenter, multinational, longitudinal study will quantify endurance and respiratory function in subjects diagnosed with MPS IVA and will better characterize the spectrum of symptoms and biochemical abnormalities in MPS IVA disease over time.
This is a one-year extension study of the use of laronidase into the spinal fluid to treat spinal cord compression in mucopolysaccharidosis I. Mucopolysaccharidosis I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Spinal cord compression occurs in this condition due to accumulation of material called glycosaminoglycans (GAG). Laronidase is the manufactured form of the enzyme alpha-l-iduronidase that is deficient in mucopolysaccharidosis I patients. The aim of this study is to determine whether laronidase is safe and effective when given into the spinal fluid as a potential non-surgical treatment for spinal cord compression due to mucopolysaccharidosis I disease.
