    Time frame: At week 16

    Proportion of responders in the 2.0 g/kg Octagam 10% and placebo arms at Week 16 relative to baseline (Week 0). A responder being defined as a patient with an increase of ≥20 points on the Total Improvement Score (TIS, a scale from 0 to 100; 20-39 points being minimal improvement, 40-59 points being moderate improvement, and ≥60 points being major improvement

Secondary outcomes

  1. Proportion of TIS Responders by Improvement Category at Week 16

    The TIS (Total Improvement Score) is a scale from 0 to 100 that allows for the discrimination between minimal, moderate and major responders depending on their improvement in the combined 6 CSM: ≥20 to 39 points being minimal improvement, ≥40 to 59 points being moderate improvement, and ≥60 points being major improvement.

    Primary: Total number of all patients who had at least minimal, moderate, or major response.

    At Least Moderate: Number of patients who had moderate or major response. At Least Major: Number of patients who had a major response.

  2. Proportion of TIS Responders by Improvement Category at Week 40

    Time frame: 40 weeks

    The TIS (Total Improvement Score) is a scale from 0 to 100 that allows for the discrimination between minimal, moderate and major responders depending on their improvement in the combined 6 CSM: ≥20 to 39 points being minimal improvement, ≥40 to 59 points being moderate improvement, and ≥60 points being major improvement.

    At Least Minimal: Total number of all patients who had minimal, moderate, or major response.

    At Least Moderate: Number of patients who had moderate or major response. At Least Major: Number of patients who had a major response.

  3. Mean Change From Baseline (Week 0) to End of First Period (Week 16) in the Modified Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI)

    Time frame: First 16 weeks

    The modified CDASI has 3 activity measures (erythema, scale, and erosion/ulceration) and 2 damage measures (poikiloderma and calcinosis) which are assessed over 15 body areas. In addition, Gottron's papules on the hands are evaluated both for activity and damage. Lastly, the activity of periungual changes and alopecia is assessed.

    Absence of skin lesions as described above is scored with "0" for each of the above described areas. Skin lesion will be scored with at least "1" (present), some lesions will be graded from "1" (less severe) to "2" (severe); others with "1", "2" or "3". For the total activity score as well as for the total damage score the sub-scores will be added up. The score for total activity ranges from 0 to 100, for total damage from 0 to 32 points. Higher scores indicate greater disease activity or greater disease damage respectively.

  4. Mean Change From End of First Period (Week 16) to End of Extension Period (Week 40) in the Modified Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI)

    Time frame: From week 16 to Week 40

    The SF-36 is a multi-purpose, short-form health survey with only 36 questions. It yields an 8-scale profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary measures and a preference-based health utility index.

    SF-36 scores ranging from 0 to 100. 0 represented the lowest possible score (worst health state) and 100 represented the highest possible score (best health state), with scores in between representing the percentages of the total possible score achieved by respondents on a given scale.

  7. Mean Change From Baseline (Week 0) to End of First Period (Week 16) and Extension Period (Week 40) in Physician's Global Disease Activity

    Time frame: From start of the trial till Week 40

    10 cm VAS assessing global disease activity from "No evidence of disease activity" to "Extremely active or severe disease activity"; Disease Activity being defined as potentially reversible pathology or physiology resulting from the myositis). Assessment completed by physician. 0 is lowest score and 10 is highest score. Higher score associated with worse outcome.

  8. Mean Change From Baseline (Week 0) to End of First Period (Week 16) and Extension Period (Week 40) in: Patient Global Disease Activity

Higher score associated with worse outcome.

  9. Mean Change From Baseline (Week 0) to End of First Period (Week 16) and Extension Period (Week 40) in: MMT-8

    Time frame: From start of the trial till Week 40

    Manual Muscle Testing - MMT-8; a set of 8 designated muscles tested bilaterally [potential score 0 - 150]. Higher score associated with better outcome.

  10. Mean Change From Baseline (Week 0) to End of First Period (Week 16) and Extension Period (Week 40) in: Health Assessment Questionnaire

    Time frame: From start of the trial till Week 40

    Health Assessment Questionnaire (HAQ); a generic rather than a disease-specific instrument; comprised of 8 sections: dressing, arising, eating, walking, hygiene, reach, grip, and activities. There are 2 or 3 questions for each section. Scoring within each section is from 0 [without any difficulty] to 3 [unable to do]. For each section the score given to that section is the worst score within the section. The 8 scores of the 8 sections are summed and divided by 8). Assessment completed by patients. Lowest score 0 highest score 24. Higher score associated with worse outcome.

    Time frame: From start of the trial until Week 40

    10 cm VAS assessing extra-muscular activity from "No evidence of disease activity" to "Extremely active or severe disease activity". It encompasses an overall evaluation for the disease activity in all the extramuscular organ systems and excludes muscle disease activity. Assessment completed by physician. 0 is lowest score and 10 is highest score. Higher score associated with worse outcome.

  17. 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 frame: Up to 40 weeks

    The TIS (Total Improvement Score) is a scale from 0 to 100 that allows for the discrimination between minimal, moderate and major responders depending on their improvement in the combined 6 CSM: ≥20 to 39 points being minimal improvement, ≥40 to 59 points being moderate improvement, and ≥60 points being major improvement.

  18. Time to Minimal, Moderate and Major Improvement in TIS

    Time frame: Up to 40 weeks

    When interpreting these time to event evaluations, one has to keep in mind that eventually all patients were treated with octagam 10%, so that differences in time to response for the Overall Period reflect this delayed start of treatment rather than the true difference between treatment with octagam 10% and placebo.

  19. Time to Confirmed Deterioration in the First Period and Overall

    Time frame: Up to 40 weeks

    Confirmed deterioration is defined as disease worsening on 2 consecutive visits. Worsening criteria are defined as either Physician's Global Disease Activity worsening ≥2cm and Manual Muscle Testing worsening ≥20% or Extra-muscular Activity worsening ≥2cm or any 3 of the following scores worsening by ≥30%: Physician's Global Disease Activity, Manual Muscle Test, Extra-muscular Activity, Patient's Global Disease Activity or Health Assessment Questionnaire.
