Study to Evaluate Efficacy and Safety in Chinese Patients With Late Onset Pompe Disease With Alglucosidase Alfa Treatmen (APOLLO-LOPD)
Study Overview
Primary Objective:
To evaluate the effect of one-year Alglucosidase alfa treatment on motor function [Six-minute walk test (6MWT) and lung function predicted Forced vital capacity (FVC)] among Chinese Late Onset Pompe Disease patients above 5 years old.
To evaluate the safety of Myozyme 20mg/kg, IV biweekly in Chinese LOPD patients above 3 years old.
Secondary Objective:
To evaluate the effect of one-year treatment with Alglucosidase alfa on improvement of manual muscle test (MMT), Maximal inspiratory and expiratory pressure (MIP and MEP)], Quick Motor Function Test scores, and health-related quality of life (SF-12) among LOPD patients over 5 years old.
Study details
Study duration per participants is approximatively 56 weeks including a 52-week treatment period.
Eligibility Criteria
You may be eligible for this study if you meet the following criteria:
-
Conditions:
Pompe's Disease
-
Age: 3 Years
-
Gender: All
Inclusion criteria :
- Patients (or and patient's legal guardian) must provide written informed consent prior to any study-related procedures
- The patient must be ≥ 3 years of age at the time of enrollment.
- For patient ≥ 3-year and < 5-year old: must be able to walk 10 meters or climb 4-step stairs independently.
- For patients ≥5-year old
- Must be able to ambulate 40 meters in 6 minutes without assistance ii. Must be able to successfully perform repeated forced vital capacity (VC) measurements in upright position of ≥ 30% predicted and ≤85% predicted.
- The patient has confirmed Pompe's Disease with at least 2 of the following condition,
- GAA enzyme deficiency from any tissue source.
- 2 confirmed GAA gene mutations.
- muscle pathology meet the diagnosis of Pompe disease.
- The patient (and patient's legal guardian if patient is legally minor as defined by
local regulation) must have the ability to comply with the clinical protocol.
- The patient, if female and of childbearing potential, must have a negative pregnancy test (beta-human chorionic gonadotropin) at baseline.
Exclusion criteria:
- Use of invasive ventilatory support (Invasive ventilation is defined as any form of ventilatory support applied with the use of an endotracheal tube.)
- Use of non-invasive ventilatory support while awake and in an upright position. (Non-invasive ventilation is defined as any form of ventilatory support applied without the use of an endotracheal tube.)
- Previously treated with Enzyme Replacement Treatment.
- A Female patient of childbearing potential with a positive pregnancy test.
- Wheelchair dependent.
- The patient has a major congenital anomaly.
- The patient has a medical condition, serious intercurrent illness, or other extenuating circumstance, in the opinion of the Investigator, may significantly interfere with study compliance, including all prescribed evaluations and follow-up activities.
- The patients with ≥5-year old are unable to ambulate 40 meters without assistance or unable to successfully perform repeated FVC of >30% and <85% predicted (upright).
