Filter by:This is a global, multicenter, prospective, observational registry of patients with Pompe disease, including those with late-onset pompe disease (LOPD) and infantile-onset pompe disease (IOPD). Both untreated patients and those being treated with an approved therapy for Pompe disease are eligible to participate. The objectives of the registry are: - To evaluate the long-term safety of Pompe disease treatments through collection of data that describe the frequency of adverse events (AEs)/serious adverse events (SAEs) occurring in Pompe disease patients - To evaluate the long-term real-world effectiveness of Pompe disease treatments - To evaluate the long-term real-world impact of Pompe disease treatments on quality of life (QOL) and patient-reported outcomes (PROs) - To describe the natural history of untreated Pompe disease
Previous studies have indicated that 13C-MRS in the ultra-high 7T magnetic resonance (MR) field is a potential non-invasive measurement method for assessing changes in muscle glycogen levels in PoD patients. However, in a single study, increases in glycogen intermediates were observed using the even more sensitive 31P-MRS technique in a mouse model of PoD and in glycogen storage disease III in humans. In fact, glycolytic intermediates such as phosphomonoesters (PME), measured by phosphorus-31P-MRS in PoD mouse models, were superior to 13C-MRS in monitoring disease progression and quantifying glycogen, indicating a significant clinical potential of 31P-MRS in humans. It has been shown that 31P-MRS can reliably quantify age- and weight-related differences as well as changes in thyroid function in human muscle metabolism. This study conducted by our institute demonstrates that the technique possesses the necessary sensitivity to measure these subtle muscular metabolic changes. However, there are currently no human 31P-MRS muscle data available for PoD. Therefore, we propose a proof-of-principle study to address this knowledge gap and contribute to establishing a new sensitive muscular biomarker that quantifies the primary disease mechanism, namely glycogen formation, for future longitudinal studies on PoD.
This is a worldwide, descriptive safety study collecting data on women and their offspring exposed to avalglucosidase alfa during pregnancy and/or lactation, to assess the risks of avalglucsodiase alfa on pregnancy and maternal complications and adverse effects in the developing fetus, neonate, and infant. - Outcomes in exposed infants, including growth and development, will be assessed through at least the first year of life. - Data will be collected for approximately 10 years.
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.
Pompe's disease is a lysosomal storage disease of autosomal recessive genetic transmission due to a deficiency in acid alpha glucosidase. This enzyme deficiency leads to glycogen overload in all cells but with a more marked expression in muscle cells. There is a great variability in the clinical manifestations and in the age of onset of symptoms depending on whether the enzyme deficiency is partial or total. The prevalence is estimated at 1 in 40,000. There is a specific treatment based on enzyme replacement therapy
In patients with Pompe disease (PD) a progressive abnormal lysosomal glycogen storage in muscle tissue leads to impaired muscle function and to degeneration of muscle fibers. Children and adults with PD present with limb-girdle muscular weakness, diaphragm weakness and impaired breathing ability. Further, patients with classic infantile PD suffer from hypertrophic cardiomyopathy. To date, the muscle pathology and the extent of the disease can be assessed using invasive techniques (e.g., muscle biopsies) or imaging (e.g., MRI). These techniques are time consuming, and especially in young patients, require anesthesia, which increases the acute risk of respiratory failure. Multispectral optoacoustic tomography (MSOT) allows the detection of specific endogenous chromophores like collagen, myoglobin or hemoglobin by using a non-invasive approach comparable to conventional ultrasound. Instead of sound waves, MSOT illuminates tissue with near-infrared light of transient energy, which is absorbed and results in thermo-elastic expansion of certain molecules. This expansion generates ultrasound waves that are detected by the same device. Multispectral illumination and unmixing then allows the precise localisation and quantification of muscle-specific subcellular structures. MSOT has already been demonstrated the potential to visualize the muscular structure and the clinical extent of muscular disease in patients with Duchenne muscle dystrophy and differentiates those patients from healthy volunteers. The aim of the study is to establish glycogen as a novel PD-specific imaging target using MSOT-imaging. It intends to identify a PD-specific muscle pathology-signature by quantification of already established targets (collagen, myoglobin, hemoglobin, glycogen if applicable). This signature will aid in differentiating PD from other muscular pathologies and healthy volunteers and will ultimately serve as a potential non-invasive monitoring biomarker.
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.
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.
The purpose of this study is to better understand the long-term health effects of Pompe disease and to determine if there are any abnormal changes in the brain and peripheral nerves. Additionally, the investigators will study the relationship between the abnormal changes in brain, nervous system findings, and developmental outcomes. The investigators will collect clinical information from clinic visits as well as assessments such as neuroimaging (magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), and diffusion tensor imaging (DTI)), cognition, academic skills, speech and language function, physical therapy and quantitative muscle ultrasound. Subjects will be in this study for at least 3 years and up to 6 years.
Clinical specimens are required from individuals with Pompe Disease to support process and analytical development for a genetically modified autologous bone marrow cell product currently in preclinical research, FTX-PD01. The intent is for this product to be investigated in a subsequent clinical trial under a future FDA IND to treat Pompe Disease. Enrolled participants provide a venous blood specimen (approximately 20mL) to be used in preclinical studies and research and development of FTX-PD01. Subjects may eventually be asked to undergo mobilized leukapheresis for bone marrow stem cell collection and their specimens will be used to further develop the FTX-PD01 cell product, including a cGMP compliant process to be applied under the future FDA IND.
