Active clinical trials for "Glycogen Storage Disease"

Primary Objective: To evaluate the safety profile of avalglucosidase alfa in participants with infantile-onset Pompe disease previously treated with alglucosidase alfa. Secondary Objective: To characterize the pharmacokinetic profile of avalglucosidase alfa and to evaluate the preliminary efficacy of avalglucosidase alfa in comparison to alglucosidase alfa.

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.

This is a prospective cohort study of children with GSD1b to evaluate their outcome after using empagliflozin for neutrophil defects.

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.

The project is a prospective study in which patients affected by adult-onset Pompe disease with c.-32-13T>G mutation in the GAA gene will be followed-up during two years to describe the natural history using clinical, imaging, histological and molecular parameters. Secondary objectives are: To identify biomarkers for assessing efficacy of future therapies based on correcting aberrant alternative splicing in Pompe patients with c.-32-13T>G mutations. To determine effectiveness of antisense oligonucleotide chemistries to restore full length GAA transcripts, GAA protein and GAA enzyme activity in fibroblasts and myoblasts obtained from skin and muscle biopsies as well as leucocytes of Pompe patients with c.-32-13T>G mutations.

Primary Objective: To describe the effect of routine practice with alglucosidase alfa in patients with IOPD ≤6 months of age, on invasive ventilation-free survival after 52 weeks of treatment. Secondary Objectives: To describe the effect of routine practice with alglucosidase alfa on invasive ventilation-free survival and survival at 12 and 18 months of age, as well as on change in left ventricular mass (LVM) Z score, Alberta Infant Motor Scale (AIMS) score, body weight, body length, and head circumference Z scores, and urinary glucose tetrasaccharide (Hex4), at Week 52 of treatment. To describe the safety, tolerability, and immunogenicity of alglucosidase alfa in the routine practice of IOPD treatment.

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.

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) 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.

The primary objective of this study is to collect whole blood from patients diagnosed with Glycogen storage disease type 1B, which will be used to support the investigation of potential therapies that address the genetic basis of this disease.

Collection and review of clinical information related to glycogen branching enzyme (GBE) deficiency, diagnosed as Glycogen Storage Disease Type IV (GSD IV) or Adult Polyglucosan Body Disease (APBD generated during clinic visits.
