Phase 3 Extension Study of the Safety and Efficacy of Aldurazyme® (Laronidase) in Mucopolysaccharidosis I (MPS I) Patients - Full Text View

Purpose

This study is being conducted to collect additional long-term efficacy and safety data of Aldurazyme® (laronidase) patients with MPS I disease. Patients who were previously enrolled in the Phase 3 Double-Blind Study will be enrolled in this study.

Primary Outcome Measures:

Change From Baseline to Week 182 in Percent Predicted Forced Vital Capacity (FVC) [ Time Frame: Baseline to Week 182 ]
Percent Predicted Forced Vital Capacity: the maximal exhaled breath volume following a maximal inhaled breath. Overall change from Baseline to Week 182 in percent predicted FVC = (observed value)/(predicted value) * 100%). A higher value indicates a greater response.
Change From Baseline to Week 182 in Six Minute Walk Test (6MWT) [ Time Frame: Baseline to Week 182 ]
Six Minute Walk Test: Distance walked (measured in Meters) in 6 minutes. A longer distance indicates a greater response.

Secondary Outcome Measures:

Change From Baseline to Week 182 in Apnea/Hypopnea Index (AHI) [ Time Frame: Baseline to Week 182 ]
Apnea/Hypopnea Index (AHI): Number of absent (apnea) and shallow (hypopnea) breaths per hour of sleep. A greater decrease in events indicates a greater response.
Change From Baseline to Week 182 in Liver Volume [ Time Frame: Baseline to Week 182 ]
Liver Organ Volume: Volume of liver measured by Magnetic Resonance Imaging (MRI). Greater decrease in volume indicates a greater response.
Change From Baseline to Week 182 in Child Health Assessment Questionnaire/Health Assessment Questionnaire (CHAQ/HAQ) Disability Index Score [ Time Frame: Baseline to Week 182 ]
CHAQ/HAQ = Patient questionnaire that measures the degree of disability on a scale of 0 (no disability) to 3 (maximal disability). A lower score indicates a greater response.
Change From Baseline to Week 182 in Active Joint Range of Motion (ROM) [ Time Frame: Baseline to Week182 ]
Active Joint Range of Motion (ROM): Shoulder Flexion Ability to maximally raise one's arm overhead without assistance. Shoulder range of motion (mean of left and right arms) measured in degrees (0-180) by goniometry. Greater degree of flexion indicates greater response.

Other Outcome Measures:

Change From Baseline to Week 182 in Urinary GAG Level [ Time Frame: Baseline to Week 182 ]
Urinary Glycosaminoglycan (GAG) Levels:

>> Concentration of GAG relative to creatinine in urine. A greater decrease in GAG level indicates a greater response.
