Study Arms:
- Placebo (Type: PLACEBO_COMPARATOR): Subjects randomized to placebo will receive 4 infusions of placebo every 4 weeks during the blinded First Period (16 weeks). If confirmed deterioration (deterioration at 2 consecutive visits) during the First Period, subjects will be switched to Octagam 10%. After response assessment at Week 16, all subjects with no confirmed deterioration and subjects switched to Octagam 10% due to confirmed deterioration but without further confirmed deterioration during the First Period will continue to receive 2.0 g/kg of Octagam 10% every 4 weeks during the subsequent 6-months open-label Extension Period. At Week 28, subjects who are stable on 2.0 g/kg Octagam 10% can be switched to 1.0 g/kg Octagam 10%, at the discretion of the investigator. Subjects randomized to placebo and switched to Octagam 10% due to confirmed deterioration, who deteriorate also during Octagam 10% treatment at 2 consecutive visits will drop-out after response assessment at Week 16 and will not enter the Extension Period.
- Octagam10% (Type: EXPERIMENTAL): Subjects randomized to Octagam will receive 4 infusions of 2.0 g/kg Octagam 10% every 4 weeks during the blinded First Period (16 weeks). If confirmed deterioration (deterioration at 2 consecutive visits) during the First Period, subjects will be switched to the alternate treatment. After response assessment at Week 16, all subjects with no confirmed deterioration during the First Period will continue receiving 2.0 g/kg of Octagam 10% every 4 weeks during the subsequent 6-months open-label Extension Period. At Week 28, subjects who are stable on 2.0 g/kg Octagam 10% can be switched to 1.0 g/kg Octagam 10%, at the discretion of the investigator. Subjects randomized to Octagam and switched to the alternate treatment due to confirmed deterioration will drop-out after response assessment at Week 16 and will not enter the Extension Period.

Based on this trial design, predict the completion outcome and termination type (if applicable).
