E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Pompe disease (acid alpha-glucosidase deficiency) |
|
E.1.1.1 | Medical condition in easily understood language |
People with Pompe disease have low levels of an enzyme called acid alpha-glucosidase. This enzyme helps the body control levels of glycogen (a type of carbohydrate) |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Long-term safety and pharmacokinetics (PK) of neoGAA |
|
E.2.2 | Secondary objectives of the trial |
Long-term effect of neo-GAA on pharmacodynamic and exploratory efficacy variables |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients with Pompe disease who previously completed a neoGAA study.
The patient and/or their parent/legal guardian is willing and able to provide signed informed consent, and the patient, if <18 years of age, is willing to provide assent if deemed able to do so.
The patient (and patient’s legal guardian if patient is <18 years of age) must have the ability to comply with the clinical protocol.
The patient, if female and of childbearing potential, must have a negative pregnancy test [urine beta-human chorionic gonadotropin] at baseline
|
|
E.4 | Principal exclusion criteria |
The patient is concurrently participating in another clinical study using investigational treatment.
The patient, in the opinion of the Investigator, is unable to adhere to the requirements of the study.
The 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.
