Filter by:This is a multiregional open-label extension (OLE) to assess the safety, tolerability, and efficacy of long-term treatment with tividenofusp alfa (DNL310), an investigational central nervous system (CNS)-penetrant intravenous (IV) enzyme replacement therapy (ERT) for Hunter syndrome (MPS II). Participants who complete at least through the Week 49 visit in Study DNLI-E-0002 and do not discontinue study intervention early and participants who complete Study DNLI-E-0007 will be enrolled in this OLE. All participants will receive DNL310 for up to 5 years from the time of entry in this OLE. Participants, site staff, and the Sponsor will remain blinded to the original treatment assignment for participants entering this OLE from Study DNLI-E-0007.
The goal of this observational study is to characterize the epidemiology and natural history of MPS diseases by building a retrospective and prospective collection of extensive phenotypic data from French MPS patients.
The study is an extension of two previous studies (HGT-HIT-046 [NCT01506141] and SHP609-302 [NCT02412787]). Participants must have completed one of the previous studies. The main aim of this study is to collect more information about the safety of the treatments, idursulfase-IT and elaprase, in children and adults with Hunter syndrome and cognitive impairment. Participants will receive the same treatment as in the previous studies.
The Mucopolysaccharidoses (MPS) are a family of genetic metabolic disorders, caused by specific enzyme deficiencies which result in accumulation of partially degraded glycosaminoglycans (GAGs) within various tissues. As GAGs are common in the body a number of different organ systems can be affected. Involvement of the upper and lower respiratory tract in MPS Type II results in significant airway compromise, with progressive airway obstruction being responsible for a significant proportion of the morbidity and mortality associated with this condition. Hearing loss is a universal finding in MPS, with a third of patients suffering with severe profound hearing loss. There is an unmet need for strong clinical evidence to guide treatment of head, neck and respiratory disease in MPS disorders. A Core Outcome Set (COS) describes the minimum outcome data that should be measured in a clinical study for a particular condition. The lack of an agreed COS for MPS II in general, and specifically head, neck and respiratory disease, makes comparison between studies difficult. There is also a lack of information detailing patient and parent perspectives on the MPS disorders. The ideal COS for head, neck and respiratory disease associated with MPS II would combine both patient/parent and clinician opinion and could be used in the design of all subsequent clinical studies. Following literature review the investigators have created a list of outcomes previously reported for qualitative and quantitative studies investigating head, neck and respiratory disease in MPS II. For the proposed research the investigators will seek opinions of patients, parents, clinicians and scientists to rate these outcomes via the Delphi method. Outcomes scored highest by patients, parents, clinicians and scientists will form a COS for head, neck and respiratory disease in MPS II. The development of a COS can help limit variability outcomes in studies investigating different interventions in MPS II.
As the HGT-HIT-046 (NCT01506141) and SHP609-302 (NCT02412787) studies will be closed, this post-trial access (PTA) program provides TAK-609 to participants in these studies for whom the benefit:risk ratio of continued treatment with idursulfase-IT remains positive.
Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
Patients with MPS II have a clinical disorder marked by progressive brain disease, neurological and somatic 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 IDS gene) in MPSII patients. Following treatment with the gene therapy patients will be followed up for a minimum of 2 years.
This is an international prospective and retrospective registry of patients with Lysosomal Storage Diseases (LSDs) to understand the natural history of the disease and the outcomes of fetal therapies, with the overall goal of improving the prenatal management of patients with LSDs.
An extension of Global Phase III open-label, multicenter designed to evaluate the Long-term safety and efficacy of study drug for the treatment of the MPS II.
The main aim of this study is to evaluate the ability of a prophylactic immune tolerizing regimen (ITR) to prevent or reduce the development of high titer anti-idursulfase antibodies in treatment-naïve participants with Hunter syndrome. In this open label, single arm study, all participants will receive ELAPRASE treatment and a prophylactic ITR. Participants will be treated with ELAPRASE for up to 104 weeks. The prophylactic ITR will start 1 day prior to the start of ELAPRASE. The prophylactic ITR will consist of a 5-week cycle of: Rituximab (intravenously [IV], weekly for 4 weeks); Methotrexate (oral, 3 times per week for 5 weeks) and intravenous immunoglobulin (IVIG) (IV, every 4 weeks of the cycle). Following the completion of 1 cycle, an assessment will be made at Month 6, 12, and 18 regarding the need for administering another 5-week cycle of the ITR. Participants will be in the study for approximately 112 weeks (including 6 weeks for screening, up to 104 weeks for treatment, and 2 weeks for follow-up).
