Active clinical trials for "Glycogen Storage Disease"

Primary Objective: Long-term safety and pharmacokinetics (PK) of avalglucosidase alfa Secondary Objective: Long-term effect of avalglucosidase alfa on pharmacodynamic and exploratory efficacy variables

Primary Objective: To evaluate the safety and tolerability of neoGAA in treatment naïve and alglucosidase alfa treated late-onset Pompe disease patients. Secondary Objective: To evaluate the pharmacokinetics, pharmacodynamics of neoGAA in treatment naïve and alglucosidase alfa treated late-onset Pompe disease patients. To evaluate the effect of neoGAA on exploratory efficacy endpoints in treatment naïve and alglucosidase alfa treated late-onset Pompe disease patients.

This study is aimed to investigate that whether the higher dose ERT improve safety and clinical outcomes of Pompe disease patients. Also, wish to develop a new therapeutic recommendation and hope that it could improve the long-term outcomes of Pompe diesease patients.

Pompe disease (also known as glycogen storage disease Type II) is a rare autosomal recessive metabolic muscle disease caused by the deficiency of acid α glucosidase (GAA), an enzyme that degrades lysosomal glycogen. As opposed to the exclusively cytoplasmic accumulation of glycogen that occurs in other glycogen storage disorders, Pompe disease is characterized by organelle bound (lysosomal) and extra-lysosomal accumulation of glycogen in many body tissues, ultimately leading to multisystemic pathology. The overall objective of this study was to evaluate the long-term growth and development of participants with infantile-onset Pompe disease with alglucosidase alfa before 1 year of age. Participants were to be followed for a 10-year period.

Pompe disease (also known as glycogen storage disease Type II) is caused by a deficiency of a critical enzyme in the body called acid alpha-glucosidase (GAA). Normally, GAA is used by the body's cells to break down glycogen (a stored form of sugar) within specialized structures called lysosomes. In patients with Pompe disease, an excessive amount of glycogen accumulates and is stored in various tissues, especially heart and skeletal muscle, which prevents their normal function. The overall objective is to evaluate the safety, pharmacokinetics (PK) and efficacy of Myozyme treatment.

Pompe disease (also known as glycogen storage disease type II, "GSD-II") is caused by a deficiency of a critical enzyme in the body called acid alpha-glucosidase (GAA). Normally, GAA is used by the body's cells to break down glycogen (a stored form of sugar) within specialized structures called lysosomes. In patients with Pompe disease, an excessive amount of glycogen accumulates and is stored in various tissues, especially heart and skeletal muscle, which prevents their normal function. This study is being conducted to evaluate the safety and effectiveness of recombinant human acid alpha-glucosidase (rhGAA) as a potential enzyme replacement therapy for Pompe disease. Patients diagnosed with infantile-onset Pompe disease who are less than or equal to 6 months old will be studied.

This study will be an open-label, prospective, interventional feasibility pilot project to study the efficacy, safety, and tolerability of UX007 (triheptanoin) on reducing hypoglycemic events in patients with GSD I. Subjects will serve as their own control. Five (5) subjects who are treatment naïve to UX007 (triheptanoin) and are already on standard dietary therapy for GSDI will be enrolled. The primary objective is to evaluate the efficacy, safety, and tolerability of UX007 (triheptanoin) in patients with GSD I. The secondary objectives include evaluating the effect of UX007 (triheptanoin) on maintaining the duration of normoglycemia between meals based on glucose monitoring (Preventing and reducing the frequency of hypoglycemia); reduction/stabilization of the dose of cornstarch; and the prevention of increased liver steatosis based on ultrasound with elastography.

This study examines the effects of individualized diet and exercise plans on muscle strength, quality of life and respiratory function in Pompe disease. Subjects will be given a diet and exercise plan based on their individual needs, which will be followed for 16 weeks. Participants will also be provided with an activity tracker in order to track their exercise activities, access to an app that will allow them to input their daily food intake, and they will also come to the University of Florida for exercise tests, respiratory tests and questionnaires.

Primary Objective: To determine the effect of avalglucosidase alfa treatment on respiratory muscle strength measured by percent (%) predicted forced vital capacity (FVC) in the upright position, as compared to alglucosidase alfa. Secondary Objective: To determine the safety and effect of avalglucosidase alfa treatment on functional endurance (6-minute walk test, inspiratory muscle strength (maximum inspiratory pressure), expiratory muscle strength (maximum expiratory pressure), lower extremity muscle strength (hand-held dynamometry), motor function (Quick Motor Function Test), and health-related quality of life (Short Form-12).

McArdle disease is a metabolic myopathy characterised by the absence of glycogen phosphorylase in skeletal muscle. Sodium Valproate is part of a group of drugs known as histone deacetylase inhibitors, which have a direct effect on chromatin. Recently a drug trial in an animal model of McArdle disease showed that sodium valproate stimulated the expression of a different isoform of the missing enzyme in skeletal muscle. A safety and feasibility study of sodium valproate in people with McArdle disease has been carried out in London (UK) and Copenhagen (DK) since January 2015. Participants will receive 20mg/Kg/day of sodium valproate for 6 months. The primary outcome measure is exercise performance assessed by cycle ergometry. Pre and post-treatment skeletal muscle biopsies will be performed to assess for glycogen phosphorylase. Together with blood analyses for safety. Additional functional exercise tests will be performed.
