E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine the efficacy of subcutaneous immunoglobulin octanorm in the maintenance treatment of DM patients who have previously responded to IGIV therapy. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of this study are: •to assess other efficacy outcomes at the end of study (Week 32 or Drop-out Visit); •to assess the effect of octanorm on Quality of Life measures; •to assess the treatment compliance of home treatment with octanorm; to evaluate the safety and tolerability of octanorm in subjects with Dermatomyositis

Subjects who have responded to IGIV treatment as assessed by the treating physician and being on a stable dose for at least 3 months on 2 g/kg bodyweight (+/- 10%) prior to study enrolment. 3. For subjects being on other medication(s) for the treatment of DM (immunosuppressants, corticosteroids): a) subject was on such medication(s) at the start of IGIV treatment in the first place, and b) received such medication(s) for at least 3 months prior to study enrolment and at a stable dose for at least 4 weeks prior to study enrolment at the maximally allowed conditions as per Table 2 (see section 4.2.1). 4. MMT-8 score ≥144, with at least 3 other CSM to be normal or near normal as per the following criteria: Visual Analogue Scale [VAS] of patient global disease activity ≤2 cm, physician’s global disease activity ≤2 cm, extra-muscular disease activity ≤2 cm; no muscle enzyme >4 times upper limit of normal due to myositis, Health Assessment Questionnaire [HAQ] ≤0.25. 5. Males or females 18 to <80 years of age. 6. Voluntarily given, fully informed written consent obtained from subject before any study-related procedures are conducted. 7. Subject must be capable and willing to understand and comply with the relevant aspects of the study protocol

E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of patients with clinically important deterioration during the treatment period up to Week 32.
