Filter by:It is a phase I open-label single-dose, dose-escalation cohort study to evaluate of the tolerance, safety, and pharmacokinetics of GNR-055 in healthy volunteers
Respiratory system affects in mucopolysaccharidosis (MPS) disease. Respiratory system symptoms are seen in almost every MPS patients and respiratory failure is one of the most common causes of death in this population. The aim of the study was to evaluate respiratory muscle strength and endurance, cough effectiveness and functional capacity in MPS patients and to defined the factors that affected the respiratory problem in this.
Phase I/II, open label, multicenter, multinational (Japan, Brazil and the US) extension study of JR-171-101 for the treatment of MPS I
The main objective of this study is to evaluate the long-term safety and tolerability of ABO-102 in participants with MPS IIIA.
Multicenter, open-label, single-group, designed to evaluate the long term efficacy and safety of study drug for the treatment of the MPS II.
This is a single center, Phase 1/2 study in which patients with Hurler syndrome who have previously undergone allogeneic hematopoietic stem cell transplantation are treated with autologous plasmablasts engineered to express α-L-iduronidase (IDUA) using the Sleeping Beauty transposon system.
This is a multicenter, multiregional, open-label study to assess the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of tividenofusp alfa (DNL310), an investigational central nervous system (CNS)-penetrant enzyme replacement therapy (ERT), designed to treat both the peripheral and CNS manifestations of Mucopolysaccharidosis type II (MPS II; Hunter syndrome). Participants, whose physicians feel they are deriving benefit, will have the opportunity to be reconsented into a safety extension and then an open-label extension for continued evaluation.
Phase I/II, open-label, multicenter, multinational (Japan, Brazil and US),designed to evaluate the safety, pharmacokinetics and explore the efficacy for the treatment of mucopolysaccharidosis type I (MPS I).
Patients with MPS IIIA have a clinical disorder marked by severe and progressive brain disease and neurological symptoms due to the accumulation of undigested glycosaminoglycans in all cells of the body. This study will be the first in human clinical trial to explore the safety, tolerability and clinical efficacy of ex vivo gene therapy (autologous CD34+ cells transduced with a lentiviral vector containing the human SGSH gene) in MPSIIIA patients. Following treatment with the gene therapy patients will be followed up for a minimum of 3 years.
Mucopolysaccharidosis (MPS) are a group of inherited, metabolic diseases caused by a deficiency of lysosomal enzymes that degrade glycosaminoglycans (GAGs). Loss of their activity results in cellular accumulation of GAGs fragments leading to progressive multi-system manifestations, with respiratory impairment. The cellular and molecular mechanisms responsible for the pulmonary impairment remain largely unknown. Specific GAGs, such as those accumulating in MPS, may act as potent inhibitors of some respiratory enzymes, like lysosomal cathepsins, depending on the nature of GAGs and their concentration. It is well established that deregulation of cathepsins levels plays a major role in the pathophysiology of some chronic respiratory diseases, such as cystic fibrosis. The role of cathepsins and their inhibitors in respiratory samples of MPS patients has never been studied. This study will focus on the status/activity of these proteases and their endogenous inhibitors in the sputum or tracheal aspiration of patients with MPS. Our main hypothesis is that high levels of GAGs in MPS patients impair the physiological activity of cathepsins and their inhibitors.
