Filter by:The purpose of this study is to determine whether the administration of iduronate-2-sulfatase enzyme in a weekly or every other week therapy frequency is safe and efficacious in patients with MPS II.
The purpose of the study is to evaluate the ability of rhASB versus placebo to enhance endurance in patients with Mucopolysaccharidosis VI (MPS VI), as evidenced by an increase in the number of meters walked in the 12 minute walk test at Week 24 compared with baseline.
The purpose of the study is evaluate the efficacy, safety, and pharmacokinetics of weekly intravenous infusions of 1 mg/kg recombinant human N-acetylgalactosamine 4-sulfatase (rhASB) in patients diagnosed with Mucopolysaccharidosis VI (MPS VI)
The purpose of the study is to evaluate the safety, efficacy and pharmacokinetics of two dose levels of weekly intravenous infusions of recombinant human N-acetylgalactosamine 4-sulfatase (rhASB) for a minimum of 24 weeks in patients diagnosed with MPS VI.
OBJECTIVES: I. Evaluate bronchoalveolar lavage fluid and serum obtained from pediatric patients with storage disorders prior to allogeneic hematopoietic stem cell transplantation (HSCT) for the presence of proinflammatory cytokines and for the production of nitric oxide by alveolar macrophages to identify possible risk factors for pulmonary complications. II. Investigate the underlying mechanism for the development of significant pulmonary complications in these patients during HSCT. III. Evaluate bronchoalveolar lavage fluid and serum obtained from these same patients at the time a pulmonary complication develops post-HSCT, or at 60 days post-HSCT if there has been no pulmonary complications.
OBJECTIVES: I. Evaluate the safety and feasibility of treating mucopolysaccharidosis II (mild Hunter syndrome) by lymphocyte gene therapy. II. Determine the levels of iduronate-2-sulfatase enzyme in these patients attained by infusing increasing doses of lymphocytes transduced with a retroviral vector designed for insertion and expression of this iduronate-2-sulfatase gene (L2SN). III. Determine the duration of survival of these transduced cells in these patients. IV. Determine whether monthly infusion of L2SN-transduced lymphocytes accomplishes metabolic correction (as measured by glycosaminoglycan excretion), decrease in liver or spleen volume, any therapeutic effect upon cardiac and pulmonary dysfunction, or any other effects from treatment.
