15 Clinical Trials for Pompe Disease
Pompe disease is a genetic condition which causes muscle weakness over time. People with Pompe disease have a faulty gene that makes an enzyme called acid alpha-glucosidase (or GAA). This enzyme breaks down a type of sugar called glycogen. Without this enzyme, there is a build-up of glycogen in the cells of the body. This causes muscle weakness and other symptoms. Pompe disease can happen at any age, but in late-onset Pompe disease, symptoms generally start from 12 months old onwards. The standard treatment for people with Pompe disease is to receive regular infusions of the GAA enzyme. This is known as enzyme replacement therapy. However, people can build up antibodies against the GAA enzyme over time. Gene therapy is used to treat conditions caused by a faulty gene. It works by replacing the faulty gene with a working gene inside the cells of the body. The working gene is delivered into the cells using certain viruses as carriers (vectors). Viruses are often used as carriers as they can easily get inside cells. The genetic material of the original virus is replaced with the working gene, so only the working gene gets inside the cells. A common virus used as a carrier in gene therapy is the adeno-associated virus (or AAV). This is like an adenovirus, which causes the common cold. The original type of AAV does not cause any harm to humans. However, people that have previously been infected with the original type of AAV may have built up antibodies against AAV. These antibodies may stop the AAV carrier with the working gene getting inside the cells. Researchers want to learn more about antibody levels against AAV and the GAA enzyme in people with late-onset Pompe disease. They also want to learn about other substances in the blood that provide more information about late-onset Pompe disease. These are known as biomarkers. In this study, older teenagers and adults with late-onset Pompe disease will take part. They will not have had gene therapy using AAV. There will be 2 groups - those who have never had enzyme replacement therapy, and those who have had enzyme replacement therapy for 6 months or more. No study treatment will be given during the study, but blood and urine samples will be taken for testing. The main aims of the study are to check antibody levels against AAV8 (a type of AAV) in people with late-onset Pompe disease who had not received any treatment using AAV, to check antibody levels against the GAA enzyme in people previously treated with GAA as part of enzyme replacement therapy, to check levels of biomarkers for Pompe disease, and to check for medical problems. In the study, people will visit the study clinic several times. Some visits may be in the person's home. The first visit is to check if they can take part. Those who can take part will have a medical examination, and have their vital signs checked. Vital signs include blood pressure, heart rate, breathing rate and temperature. Blood samples will be taken to check antibody levels against the GAA enzyme and against AAV8. Blood and urine samples will also be taken to check for biomarkers for Pompe disease. Blood and urine samples will be taken about every 4 months for up to 2 years.
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
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.
This is a longitudinal natural history study of Infantile Pompe disease. The investigators will regularly collect and review medical information regarding the diagnosis of Pompe disease, response to enzyme replacement (ERT) using alglucosidase alfa (Lumizyme/Myozyme) and response to immunosuppressive therapy in cases at risk for developing or those who have developed high and sustained antibodies to ERT. To follow the long-term outcomes, we will collect medical records including but not limited to the diagnosis, clinical parameters, assessments for clinical monitoring, and laboratory values including antibody testing results.
The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: * To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. * To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. * To characterize the Pompe disease population. * To evaluate the long-term effectiveness of alglucosidase alfa.
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.
Study Objectives: 1) assess the safety and feasibility of high-dose inspiratory muscle training (IMT) delivered remotely in Late-onset Pompe Disease (LOPD) and 2) determine its effects on respiratory and patient-reported outcomes.
This is a Phase 3, open-label, multicenter study to evaluate the safety, PK, efficacy, PD, and immunogenicity of Cipaglucosidase Alfa/Miglustat treatment in enzyme replacement therapy (ERT)-experienced and ERT-naïve pediatric subjects with Pompe disease, aged 0 to \< 18 years
This Sub-registry is a multicenter, international, longitudinal, observational, and voluntary program designed to track pregnancy outcomes for any pregnant woman enrolled in the Pompe Registry, regardless of whether she is receiving disease-specific therapy (such as ERT with alglucosidase alfa or avalglucosidase alfa) and irrespective of the commercial product with which she may be treated. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician. The primary objective of this Sub-registry is to track pregnancy outcomes, including complications and infant growth, in all women with Pompe disease during pregnancy, regardless of whether they receive disease-specific therapy, such as ERT with alglucosidase alfa or avalglucosidase alfa.
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.
FLOWER is a completely virtual, nationwide, real-world observational study to collect, annotate, standardize, and report clinical data for rare diseases. Patients participate in the study by electronic consent (eConsent) and sign a medical records release to permit data collection. Medical records are accessed from institutions directly via eFax or paper fax, online from patient electronic medical record (EMR) portals, direct from DNA/RNA sequencing and molecular profiling vendors, and via electronic health information exchanges. Patients and their treating physicians may also optionally provide medical records. Medical records are received in or converted to electronic/digitized formats (CCDA, FHIR, PDF), sorted by medical record type (clinic visit, in-patient hospital, out-patient clinic, infusion and out-patient pharmacies, etc.) and made machine-readable to support data annotation, full text searches, and natural language processing (NLP) algorithms to further facilitate feature identification.
