Safety and Efficacy Evaluation of Repeat neoGAA Dosing in Late Onset Pompe Disease Patients.

Completed · Phase 1

Conditions studied: Pompe Disease, Glycogen Storage Disease Type II (GSD II), Acid Maltase Deficiency

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• For both Group 1 and Group 2:
• Male or female patients with confirmed acid α-glucosidase (GAA) enzyme deficiency from any tissue source and/or confirmed GAA gene mutation and without known cardiac hypertrophy.
• Patient willing and able to provide signed informed consent
• Patient is able to ambulate 50 meters (approximately 160 feet) without stopping and without an assistive device. Use of assistive device for community ambulation is appropriate.
• Patient has a forced vital capacity (FVC) in upright position of ≥50% predicted.
• The patient, if female and of childbearing potential, must have a negative pregnancy test [urine beta-human chorionic gonadotropin (β-hCG)] at baseline.
• Group 2 patients only:
• The patient has been previously treated with alglucosidase alfa for at least 9 months.

You may not qualify if…

• For both Group 1 and Group 2:
• Patient is wheelchair dependent.
• Patient requires invasive-ventilation (non-invasive ventilation is allowed).
• Patient is participating in another clinical study using investigational treatment.
• Patient, in the opinion of the Investigator, is unable to adhere to the requirements of the study.
• Patient has clinically significant organic disease (with the exception of symptoms relating to Pompe disease), including clinically significant cardiovascular, hepatic, pulmonary, neurologic, or renal disease, or other medical condition, serious intercurrent illness, or extenuating circumstance that, in the opinion of the Investigator, precludes participation in the study or potentially decreases survival.
• Patient cannot submit to MRI examination because of a formal contraindication such as a pacemaker, implanted ferromagnetic metals, anxiety disorder, etc.
• Group 1 only:
• Patient has had previous treatment with alglucosidase alfa or any other enzyme replacement therapy (ERT) for Pompe disease.
• Group 2 only:
• Patient has a high risk for a severe allergic reaction to neoGAA (i.e. previous moderate to severe anaphylactic reaction to alglucosidase alfa and/or patient has immunoglobulin (Ig) E antibodies to alglucosidase alfa, and/or a history of sustained high immunoglobulin G (IgG) antibody titers to alglucosidase alfa that in the opinion of the investigator suggest a high risk for an allergic reaction to neoGAA).
• The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
