Filter by:The purpose of this study is to determine whether growth hormone is a safe and effective treatment for short stature in children with Mucopolysaccharidosis type I, II, and VI.
The purpose of this study is to see if treatment with an antigen-specific immunosuppressive can decrease or stop an antibody response to laronidase (Aldurazyme®) during enzyme replacement therapy with laronidase in severe Mucopolysaccharidosis I (MPS I) participants.
This protocol (GENEFU) provides a mechanism for the 15-year followup period that the FDA requires for all participants in gene transfer protocols and assures that adequate followup can be maintained for a wide variety of participants on different individual gene therapy protocols at St. Jude Children's Research Hospital. GENEFU serves as an umbrella protocol for long-term follow-up (LTFU) for recipients of gene therapy/gene marked (GT/GM) products at St. Jude Children's Research Hospital. The FDA has recommended methods to assess the risk of delayed adverse events after GT/GM and has provided specific requirements regarding the duration and design of LTFU observations. This protocol is intended to provide LTFU in accordance with the FDA guidelines for those who received a GT/GM product as part of a St. Jude-sponsored clinical trial or compassionate use treatment plan. The protocol calls for a physical examination or general health evaluation and collection of required blood samples annually for up to 15 years after the last receipt of a GT/GM product. Goals will be to obtain clinical histories in order to detect late clinical outcomes suggestive of retroviral or lentiviral disease, including but not limited to cancer/second malignancies, neurologic disorders, autoimmune disorders, and hematologic disorders. Blood samples will be archived and tested when clinically or scientifically indicated, as in the event of development of a second malignancy. This prospective cohort study will utilize descriptive statistics in the analysis of long-term late effects outcomes. It offers a uniform approach to long-term safety monitoring in research participants who have received a gene-transduced product as part of St. Jude-sponsored GT or GM protocols and compassionate use treatment plans.
Eligible research subjects will receive an unrelated umbilical cord blood transfusion as a possible cure for their inherited metabolic disease. A portion of cord blood cells (ALD-101) will be separated from the cord blood unit and given approximately 4 hours after the standard cord blood transfusion. The study will test if the supplemental cells will increase the speed at which normal levels of circulating blood cells are re-established after transplant.
This protocol will examine whether the enzyme alpha-L-iduronidase (Laronidase), delivered into the spinal fluid of patients with Hurler syndrome at intervals before and after bone marrow transplant, is a safe and effective approach to slow the neurologic degeneration seen in Hurler patients undergoing transplantation.
Study TKT024EXT was a long-term, single-arm, open-label extension of Study TKT024, a one year Phase 2/Phase 3 registration study. The primary objective of this extension study was to collect long-term safety and clinical outcome data in Mucopolysaccharidosis II (MPS II), also known as Hunter Syndrome, from the Phase 2/Phase 3 Study TKT024. All patients enrolling into this study received weekly active treatment with idursulfase, the primary dosing regimen investigated in Study TKT024. Hunter Syndrome is an X-linked recessive lysosomal storage disease caused by a deficiency of iduronate-2-sulfatase, an enzyme required to catabolize glycosaminoglycans (GAGS) in cells. As a result, GAGs accumulate in the lysosomes leading to cellular engorgement, organomegaly, tissue destruction, and organ system dysfunction. Hunter Syndrome is a rare disease with an estimated incidence of 1 in 162,000 live births.
The objective of this study is to determine the safety of once weekly dosing of idursulfase 0.5 mg/kg administered by intravenous (IV) infusion for male Hunter syndrome patients ≤ 5 years old.
The purpose of this study is to determine if laronidase is present in the breast milk of post-partum women receiving Aldurazyme® (laronidase) and the effects of Aldurazyme (laronidase) on the growth, development, and immunologic response of their breastfed infants.
The purpose of the study is to evaluate the safety and efficacy of two dose levels of Naglazyme in infants under the age of one year who have MPS VI by monitoring physical appearance, x-ray of the skeletal system and growth.
This is a multi-center, open label, study conducted to evaluate the safety of laronidase administered by intravenous drip infusion in Japanese patients with MPS I disease. Following baseline evaluation, patients will receive weekly infusions of JC0498 at an intravenous dose of 100 units/kg. Patient safety will be monitored continuously throughout the trial. In addition, the effects of JC0498 treatment in this patient population will be assessed by periodically evaluating aspects of MPS I disease in patients at scheduled intervals over the duration of the trial. Since patients may be eligible for the trial if they have received JC0498, a portion of the data may be captured retrospectively and recorded onto the case report forms (CRFs). This study represents the first good clinical practice (GCP) effort to characterize MPS I in the Japanese population and evaluate the effects of JC0498 on disease manifestations.
