Active clinical trials for "Glycogen Storage Disease Type II"

This Phase I/II open-label, randomized, dose-escalation study will assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of VAL-1221 versus Myozyme®/Lumizyme® in participants with late-onset glycogen storage disease-II (GSD-II) (Pompe disease)

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.

Hypothesis: the effectiveness of treatment of Pompe disease with rhGAA enzyme replacement therapy (ERT) is limited at least in part because patients develop antibodies against the provided rhGAA enzyme. Treatment with Zavesca® prior to infusion may dampen or eliminate the anti-rhGAA immune response in patients receiving ERT, thereby allowing for greater ERT efficacy. Treatment with Zavesca® before a enzyme replacement therapy (ERT) may decrease the severity of, or eliminate infusion associated reactions (IAR) in people with Pompe Disease receiving ERT.

This is a Phase 2 open-label, multiple dose study of BMN 701 administered by IV infusion every 2 weeks (qow) to patients with late-onset Pompe disease.

Study 701-301 is a single-arm, open-label, switchover study in patients with late-onset Pompe disease who have been receiving treatment with recombinant human acid alpha-glucosidase (rhGAA) for 48 weeks or longer. Ambulatory patients who have mild to moderate respiratory impairment will switch directly to receive BMN 701 20 mg/kg by IV infusion every other week. All participants will receive active drug. No dose of existing therapy will be missed - experimental drug is started immediately.

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.

Funding Source- FDA OOPD The purpose of this study is to investigate the safety and efficacy of clenbuterol on motor function in individuals with late-onset Pompe disease (LOPD) who are treated with enzyme replacement therapy (ERT).

In this study the study team proposes to investigate the efficacy of albuterol on motor function of individuals with Late Onset Pompe Disease (LOPD) who are receiving enzyme replacement therapy, given albuterol was well-tolerated in patients with Late Onset Pompe Disease.

A Phase 1/2, open-label, multicenter, multiple dose escalation study of BMN 701 administered by intravenous infusion every 2 weeks over a 24-week treatment period to patients with late-onset Pompe disease.

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 exploratory study is to evaluate the safety and efficacy of alternative dosing regimens of alglucosidase alfa in patients with Pompe disease who have not demonstrated an optimal response to the standard dosing regimen of 20 mg/kg every other week after a minimum of 6 months treatment immediately prior to study entry.
