Filter by:Establish of high-risk screening criteria to earlier identify possible childhood LOPD for early treatment and better prognosis. Therefore, validation of the high-risk screening criteria for childhood LOPD will be critical for identifying children of LOPD in Taiwan.
Pompe disease is known as glycogen storage disease type II, an autosomal recessive disease that results from acid alpha-glucosidase (GAA) deficiency leading to lysosomal glycogen accumulation. Patients with classic infantile form have less than 1% of enzyme activity, which explains severe impairment before one year with rapid death without treatment, while later-onset form shows progressive symptoms later in childhood (juvenile form) or adulthood (adult form). Enzyme replacement therapy (ERT) consists of periodic intravenous infusion of missing GAA produced by the recombinant method. ERT improves significantly the cardiac function and the children's survival in classic infantile form. This therapy has been approved for all patients with Pompe's disease in the United States and the European Union since 2006, but its efficacy was not clear for patients with later-onset form. Recent studies show motor improvement in adult patients, but there is little published data for the juvenile form disease. A separate analysis of juvenile form is justified as patients are still in a developmental stage and show clinical symptoms early in life, may have more severe disease and a different response to ERT. The recommendation is no treatment in the absence of clinical symptoms, but the consensus does not stratify patients into juvenile- or adult-onset form. ERT is an expensive long-term therapy, and its administration every 2 weeks in the hospital is a great limitation for patients. Therefore, an evaluation of the treatment effect in patients with the juvenile form is necessary.
The project will use carbon-13 magnetic resonance spectroscopy to assess whether high glycogen levels in skeletal muscle of patients with Glycogen Storage Diseases is a prelude for muscle damage. Patients with Glycogen Storage Diseases will be examined using carbon-13 MR-spectroscopy to quantify the glycogen levels in lumbar, thigh and calf-muscles. The pattern of glycogen concentration will be compared to the pattern of muscle atrophy found in the literature.
This is a single group, treatment, Phase 3, open-label study to assess efficacy, safety, pharmacokinetic (PK), pharmacodynamics (PD) of avalglucosidase alfa in treatment-naïve male and female participants with IOPD. Study details include: - Study duration: Screening - up to 4 weeks; - Primary Analysis Period (PAP) - 52 weeks; - Extended Treatment Period (ETP) - 52 weeks; - Extended Long term Treatment Period (ELTP) - 104 weeks; 4-week follow-up period for a total study duration - up to 4.08 years. - Treatment duration: Up to 4 years - Visit frequency: every other week and potentially every week
The primary aim is to characterize the prevalence, severity and quality of musculoskeletal nociceptive pain in adult patients with neuromuscular disorders (NMD). The secondary objectives are to evaluate whether severity and distribution of muscle pain is associated with muscle function, and to assess whether muscle pain is associated with alterations of muscle elasticity and muscle stiffness. Results of patients with neuromuscular disorders will be compared to age- and gender-matched healthy volunteers. Approx. 70 patients with neuromuscular disorders and 20 healthy volunteers will be enrolled, including patients with the following neuromuscular disorders: histologically confirmed inclusion body myositis (IBM), genetically confirmed late-onset Pompe disease (LOPD), genetically confirmed spinal muscular atrophy type 3 (SMA3), genetically confirmed facio-scapulo-humeral muscle dystrophy (FSHD), genetically confirmed myotonic dystrophy type 1 or type 2 (DM1, DM2). The duration of patient recruitment will be around 12 months.
Primary Objective: To describe the effect of routine practice with alglucosidase alfa in patients with IOPD ≤6 months of age, on invasive ventilation-free survival after 52 weeks of treatment. Secondary Objectives: - To describe the effect of routine practice with alglucosidase alfa on invasive ventilation-free survival and survival at 12 and 18 months of age, as well as on change in left ventricular mass (LVM) Z score, Alberta Infant Motor Scale (AIMS) score, body weight, body length, and head circumference Z scores, and urinary glucose tetrasaccharide (Hex4), at Week 52 of treatment. - To describe the safety, tolerability, and immunogenicity of alglucosidase alfa in the routine practice of IOPD treatment.
This is a Phase 3, open-label, multicenter study to evaluate the safety, efficacy, PK, PD, and immunogenicity of cipaglucosidase alfa/miglustat treatment in ERT-experienced and ERT-naïve pediatric subjects with IOPD.
This project is a randomized controlled trial to use a mobile health journal, called Zamplo (formerly known as MyHealthJournal or ZoeInsights), to record patient reported outcomes (PROM) in patients with metabolic disorders. The objective of the study is to assess the feasibility, acceptability and potential effectiveness of the Zamplo. The primary hypothesis is as follows: The Zamplo platform will significantly increase patient activation at 6 months post-baseline, defined as an individual's knowledge, skill, and confidence for managing their health and health care. The primary outcome is as follows: Patient activation following the use of Zamplo will serve as the primary outcome of interest and will be measured by the Patient Activation Measure (PAM) 13. The PAM 13 shows the degree of the patient's ability to manage their health with confidence by providing a total patient activation score. Brief Background: This project is a randomized controlled trial to use a mobile health journal, called Zamplo, to record patient reported outcomes (PROM) in patients with metabolic disorders. Zamplo is a software as a service (SaaS) digital platform on both iOS and Android platforms that allows real-time entry of patient symptoms and response to medications. It provides the patients with an interface to see their progress, store questions that they will ask at the next clinic visit, record their health data and use their data to engage in their health outcomes. MAGIC Clinic Ltd., which is the largest clinic in Alberta that manages metabolic disorders such as Fabry disease, Pompe disease, and Gaucher disease, will provide access to Zamplo to patients free-of-charge to evaluate its utility in managing the symptoms of their disease. Brief Study Design: The study is a two-armed randomized controlled design with 1:1 allocation to treatment (Zamplo app group) or control (usual care) arms, with assessments at four time points: baseline, 1 month, 3 months (primary outcome), 6 months and 12 months follow-up post-baseline. This is an open-label trial. The investigators intend to recruit 150 participants in this study, with 75 of them being controls. Inclusion Criteria: Adult patients with a diagnosis of metabolic disease Access to a smartphone with data connection Willingness to devote 10-15 mins of time in a day to log medications and notes Able to speak and write English sufficiently to complete questionnaires. Exclusion Criteria: Insufficient cognitive function to participate in the study The use of any electronic application requires some competency with the software on a cellphone, downloading the application and entering the data. Some patients who are elderly may not be familiar with this technology and would be excluded.
Our aims are to investigate the acute and long term effect of ERT on exercise capacity; comparing the effect of different ERT dosages (as prescribed by the clinician according to clinical judgment) and assessing the relationship between enzyme blood level and exercise capacity. Such evaluation may allow a more objective quantification of the response to ERT.
Health related quality of life (HrQoL), is "the patient's subjective perception of the impact of his disease and its treatment on his daily life, physical, psychological and social functioning and well-being" and thus constitutes a patient reported outcome (PRO) of utmost importance. Generic HrQoL instruments can by definition not capture disease-specific parameters nor are they sensitive enough to detect their changes. In this study, a disease-specific HrQoL questionnaire for children and adolescents will be developed. Patients and parents will be involved in focus groups and interviews to identify relevant contents. The instrument will be tested for validity and reliability.
