90 Clinical Trials for Various Conditions
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.

Glycogen Storage Disease Type II
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.
Pompe Disease
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.

Pyridostigmine is an acetylcholinesterase inhibitor, which degrades acetylcholine at the neuromuscular junction. Based on recent studies, pyridostigmine may be an effective adjuvant treatment for people with Pompe disease, as it increases the functional impact of this neurotransmitter. Hypothesis: the use of pyridostigmine in Pompe disease will improve transmission of acetylcholine across the neuromuscular junction, skeletal muscle function, respiratory function, and quality of life.
Pompe Disease
This study intends to evaluate dynamic respiratory motor performance as a valuable measure of pulmonary function in adults with late-onset Pompe disease. The investigators will adopt a strategy that includes comprehensive evaluations of respiratory volume, flow, and timing parameters during resting and loaded breathing. These evaluations will then be associated to the standard clinical measure of maximal inspiratory pressure, the static inspiratory muscle function, as well as magnetic resonance imaging of thoracic expansion and diaphragmatic descent at rest and with exertion. Outcomes in participants with late-onset Pompe disease will be contrasted to the function of age- and gender-matched control subjects. This approach will enable the investigators to evaluate the relationship between dynamic diaphragmatic function and respiratory motor function.

Pompe Disease
A recombinant AAV vector has been generated to carry the codon-optimized acid alpha-glucosidase (coGAA) gene expressed from a human desmin enhancer/promoter (DES). The proposed clinical trial is a within-participant, double-blind, randomized, phase I controlled study evaluating the toxicology, biodistribution and potential activity of re-administration of rAAV9-DES-hGAA injected intramuscularly into the TA. Nine participants (18 to 50-years old) who reside within the United States with Late-Onset Pompe Disease (LOPD) will be included. The goal of the immune modulation strategy is to ablate B-cells (Rituximab and Sirolimus) prior to the initial exposure to the study agent in one leg and the subsequent exposure of the same vector to the contralateral leg after four months. At each study agent dosing, the contralateral leg will receive excipient. Patients will act as their own controls. Repeated measures, at baseline and during the following 3 months after each injection, will assess the safety, biochemical and functional impact of the vector.
