The objectives of this study are to characterize MPS VII disease presentation and progression and assess long-term effectiveness and safety, including hypersensitivity reactions and immunogenicity of vestronidase alfa.
The primary objective of the study is to evaluate the long-term safety of UX003 in subjects with MPS 7.
The primary objective was to evaluate the effect of UX003 treatment in pediatric MPS VII participants less than 5 years of age on safety, tolerability, and efficacy as determined by the reduction of urinary glycosaminoglycans (uGAG) excretion.
The Phase 3 study will use a novel randomized, intra-subject placebo-controlled, single crossover design, referred to as Blind Start, to evaluate the safety and efficacy of UX003. The Blind Start is a novel design whereby participants will be randomized to 1 of 4 groups, each representing a different treatment sequence, and will cross over to UX003 at different pre-defined time points in a blinded manner. All groups will receive a minimum of 24 weeks treatment with 4 mg/kg UX003 every other week (QOW).
This single-institution, phase II study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) using busulfan- and fludarabine-based conditioning regimens with busulfan therapeutic drug monitoring (TDM) for patients with various inherited metabolic disorders (IMD) and severe osteopetrosis (OP).
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.
The primary objective of this clinical trial is to evaluate the ability to achieve and sustain donor engraftment in patients with lysosomal and peroxisomal inborn errors of metabolism undergoing hematopoietic stem cell transplantation (HCT).
