NCT ID: NCT06150820 Recruiting - Clinical trials for Pompe Disease (Late-onset)

A Study About Antibody Levels and Biomarkers in the Blood in People With Late-onset Pompe Disease

Start date: February 1, 2024
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05272969 Recruiting - Clinical trials for Pompe Disease (Late-onset)

Pompe & Pain - Study to Assess Nociceptive Pain in Adult Patients With Pompe Disease

Start date: March 31, 2022
Phase:
Study type: Observational

The primary aim of this nationwide, explorative, cross-sectional study in Germany is to characterize the prevalence, severity and quality of musculoskeletal pain in adult patients with late-onset Pompe disease (LOPD). The secondary objectives are to evaluate whether muscle pain is associated with muscle function, to assess whether muscle pain is associated with alterations of muscle tissue, and whether vitamin D metabolism and polymorphisms of ACE and ACTN3 genes may contribute to an increased level of perceived musculoskeletal pain. In a second step, exome sequencing of genes associated with musculoskeletal pain will be analyzed. Results of LOPD patients will be compared to patients with neuromuscular disorders with a similar distribution of muscle weakness and/or musculoskeletal pain.

NCT ID: NCT05083806 Recruiting - Pompe Disease Clinical Trials

MSOT in Pompe Disease

SPOT_PD
Start date: May 17, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04929002 Recruiting - Clinical trials for Pompe Disease (Late-onset)

Carbon-13 Magnetic Resonance Spectroscopy in Glycogen Storage Diseases

Start date: December 10, 2021
Phase:
Study type: Observational

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.

NCT ID: NCT04907162 Completed - Healthy Clinical Trials

Musculoskeletal Nociceptive Pain in Participants With Neuromuscular Disorders

Start date: April 15, 2021
