Pompe DiseaseGlycogen Storage Disease Type II2 more

Pompe disease 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 infants with severe cases of Pompe disease (called Classical Infantile Pompe disease), an excessive amount of glycogen accumulates and is stored in various tissues, especially heart, skeletal muscle, and liver, which prevents their normal function. This study 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 Classical Infantile Pompe disease who have a small, but inactive, amount of natural GAA enzyme present in their bodies (called Cross-Reacting Immunologic Material-Positive or "CRIM (+)" patients), will be studied.

Glycogen Storage Disease Type II

Primary Objective: To evaluate effect of 52-week treatment with Alglucosidase Alfa in the extension of survival and improvement of cardiomyopathy measured by Left Ventricular Mass Index in Chinese patients with infantile-onset Pompe Disease. Secondary Objectives: To observe the improvement of physical growth, motor and cognitive development of 52-week treatment with Alglucosidase Alfa in infantile-onset Pompe Disease from the baseline. To observe the efficacy on survival free of invasive ventilation, use of any ventilation support of 52- week treatment with Alglucosidase Alfa in Chinese patients with infantile-onset Pompe Disease. To evaluate the safety and tolerability of Alglucosidase Alfa in Chinese patients with infantile-onset Pompe Disease.

Albuterol in Individuals With Late Onset Pompe Disease (LOPD)

Pompe Disease

Albuterol is a drug approved by the US Food and Drug Administration (FDA) for treating breathing problems such as asthma. Studies have shown that albuterol may be beneficial in improving muscle function in people with late-onset Pompe disease. The purpose of this study is to evaluate whether albuterol is safe and effective for improving muscle function in people with late-onset Pompe disease, whether or not they are receiving enzyme replacement therapy (ERT). For this study, albuterol is considered an investigational drug. The word "investigational" means albuterol is not approved by the FDA for individuals with late-onset Pompe disease.

Late-Onset Treatment Study Extension Protocol

Pompe Disease (Late-Onset)Glycogen Storage Disease Type II (GSD-II)2 more

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 objective of this extension study is to assess the long-term safety and efficacy of alglucosidase alfa treatment in patients with Late-Onset Pompe Disease who were previously treated under the placebo-controlled, double-blind study AGLU02704 (NCT00158600).

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 and efficacy of rhGAA in patients with advanced Late-onset Pompe disease.

rhGAA in Patients With Infantile-onset Glycogen Storage Disease-II (Pompe Disease)

Glycogen Storage Disease Type IIPompe Disease2 more

Glycogen Storage Disease Type II ("GSD-II"; also known as Pompe disease) 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 GSD-II, 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 GSD-II. Patients diagnosed with infantile-onset GSD-II who are greater than 6 months old, but less than or equal to 36 months old will be studied.

Pompe Disease (Late-Onset)Glycogen Storage Disease Type II (GSD II)1 more

This is an open-label, multicenter study of participants with late-onset Pompe disease naive to treatment with enzyme replacement therapy (ERT). The primary objective of this study is to evaluate glycogen clearance in muscle tissue samples collected pre and post alglucosidase alfa treatment in participants with Late-Onset Pompe disease. The secondary objectives are to characterize the disease burden in participants with late-onset Pompe disease and explore imaging, histologic, and functional assessments in these participants and to explore potential plasma or urine biomarkers relative to late-onset Pompe disease and participant's response to treatment with alglucosidase alfa (Myozyme®/Lumizyme®/GZ419829).

Developing a Management Approach for Patients With "Late-Onset" Pompe Disease

Pompe DiseasePompe Disease (Late-onset)1 more

This is an observational study with no study related treatment of interventions. The purpose of the study is to investigate and document disease specific clinical symptoms in newborns, infants and children with Pompe disease without cardiomyopathy identified in newborn screening(NBS). There will be baseline, months 6 and months 12 visits for infants and newborns (infants study). For children of ages 24 months to 54 months, there will be baseline, year 1 and year 2 visits (children study). The study has four goals: To study and record disease specific clinical symptoms in newborns, infants and children with Pompe disease without cardiomyopathy (disease of the heart muscle) in the first year of life identified through newborn screening (NBS) To devise an approach to characterize early musculoskeletal (muscles and joints) involvement in subjects with the "late-onset" GAA variant identified by NBS including ability to collect research information via virtual health platforms. To determine criteria to start preventative therapies including enzyme replacement therapy (ERT) in patients with clinical features of Pompe disease identified via NBS To document parental coping and anxiety/emotional distress overtime using quality of life questionnaires after a child is diagnosed with late onset Pompe disease via NBS
