Outcome Measures

Primary Outcome Measures :

1. Hemoglobin [ Time Frame: Baseline, months 9, 12 and 24 ]
   Median and interquartile range. Baseline is the value obtained from the parent study: PB-06-005 for 30 and 60 Units/kg arms and PB-06-002 from Switchover arm.

Secondary Outcome Measures :

1. Chitotriosidase [ Time Frame: Baseline, months 9, 12 and 24 ]
   Chitotriosidase. Baseline is the value obtained from the parent study: PB-06-005 for 30 and 60 Units/kg arms and PB-06-002 from Switchover arm.
2. Spleen Volume [ Time Frame: Baseline, months 12 and 24 ]
   Spleen volume measured by MRI (or ultrasound). Baseline is the value obtained from the parent study: PB-06-005 for 30 and 60 Units/kg arms and PB-06-002 from Switchover arm.
3. Platelet Count [ Time Frame: Baseline, months 9, 12, 24 and 33-36 ]
   Platelet count. Baseline is the value obtained from the parent study: PB-06-005 for 30 and 60 Units/kg arms and PB-06-002 from Switchover arm.
4. Liver Volume [ Time Frame: Baseline, months 12 and 24 ]
   Liver volume by MRI or Ultrasound. Baseline is the value obtained from the parent study: PB-06-005 for 30 and 60 Units/kg arms and PB-06-002 from Switchover arm.
