Primary Outcome(s)

Primary end point(s): Proportion of responders in the 2.0 g/kg Octagam 10% and placebo arms at Week 16. A responder is defined as a subject with an increase from baseline (Week 0) of =20 points on the Total Improvement Score (TIS) and who has not met "Confirmed
Deterioration" criteria at 2 consecutive visits as defined in Section 4.3.1 up to (including) Week 16.

Secondary Objective: To evaluate the beneficial effect of Octagam 10% in subjects with active DM by assessing different parameters and scores at Week 16 and Week 40;
To confirm the sustained benefit of treatment with Octagam 10% by assessing the primary response measures at Week 40;
To evaluate the safety and tolerability of Octagam 10% in subjects with DM.

Timepoint(s) of evaluation of this end point: Week 16

Main Objective: To provide confirmatory data on the beneficial effect of 2.0 g/kg of Octagam 10% given every 4 weeks compared with placebo in subjects with active DM based on the percentage of responders at Week 16.

Secondary Outcome(s)

Secondary end point(s): -Proportion of TIS responders by improvement category (minimal, moderate, major) at Week 16 and Week 40.
-Mean change from baseline (Week 0) to end of First Period (Week 16) in the modified Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI).
- Mean change from end of First Period (Week 16) to end of Extension Period (Week 40) in the modified CDASI.
-Mean change from Baseline (Week 0) to end of First Period (Week 16) and Extension Period (Week 40) in:
- SF-36v2 Health Survey;
- Individual 6 CSM used for TIS calculation.
- Mean TIS from Baseline (Week 0) to end of First Period (Week 16) and from Baseline (Week 0) to end of Extension Period (Week 40).
- Time to minimal, moderate and major improvement in TIS.
- Time to confirmed deterioration in the First Period and overall.
- Proportion of subjects in each treatment arm who met confirmed
deterioration criteria up to (including) Week 16

Timepoint(s) of evaluation of this end point: Week 16 and 40
