| Experimental: Study Epochs 1-4<br>Epoch 1 (13 weeks): Pharmacokinetic (PK) assessment at 2nd to last infusion (in all participants ≥12 years of age). Participants will be treated intravenously once every 3 or 4 weeks at same monthly equivalent dose as prior to the study. Epoch 2 (12-16 weeks): PK assessment (in first 15 participants ≥12 years of age) at 9th infusion to determine adjusted dose for Epoch 3 and individually adapted dose for Epoch 4. Participants will be treated subcutaneously every 7 days at a dose of IGSC, 20% that is 145% of the weekly equivalent of the IV dose in Epoch 1. Epoch 3 (12 weeks): Participants will be treated subcutaneously every 7 days using the adjusted dose determined in Epoch 2. The individually adapted dose for use in Epoch 4 will also be determined. Epoch 4 (40 weeks): Participants will be treated subcutaneously once every week at the individually adapted dose determined in Epoch 3.

| Quality of Life- Pediatric Quality of Life Inventory^TM (PEDS-QL^TM) (Observer: Parent) for the Age Group 2 to 7 Years | The Peds-QL is a generic Health-Related Quality of Life (HR QoL) instrument designed specifically for a pediatric population. It captures the following domains: general health/activities, feelings/emotional, social functioning, school functioning. Higher scores indicate better quality of life (QoL) for all domains of the Peds-QL. This modular instrument uses a 5-point scale: from 0 (never) to 4 (almost always). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. 4 dimensions (physical, emotional, social, & school functioning) are scored. 2 summary scores (Psychosocial Health Summary, and Physical Health Summary) are presented, along with a total score. | Up to 20 months (throughout entire study) |
