Clinical Trial Alert: Phase 3 Study of IgPro20 in Adults with Dermatomyositis

Researchers partnering with CSL Behring, are seeking adults living with dermatomyositis to participate in a phase 3 clinical trial to evaluate the safety, efficacy, and duration of effect of IgPro20 (human immunoglobulin G) to treat dermatomyositis. IgPro20 is being evaluated for the ability to reduce inflammation and modify the abnormal immune response that causes dermatomyositis, thereby potentially reducing disease symptoms and improving function in people with the disease.

This study is a randomized, double-blind, placebo-controlled study with an open-label extension. This means that participants will be randomly assigned to either IgPro20 or an inactive placebo control over the course of the study. The total trial duration for each participant will be at least one year, with monthly visits in the first year and less frequent visits thereafter. Following the study period, all eligible participants will have the opportunity to receive IgPro20 during an open-label extension period.

The drug/placebo will be administered subcutaneously (under the skin). The effect of IgPro20 will be evaluated by a measure known as “responder status” based on Total Improvement Score (TIS) assessments, which incorporate the findings of physical and clinical tests conducted on weeks 17, 21, and 25 of the study.

To be eligible, individuals must meet the following inclusion criteria:

• Diagnosis of at least probable idiopathic inflammatory myopathies (IIM) per European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) Classification Criteria
• Disease severity defined by physician global activity visual analog scale (VAS) with a minimum value of 2 cm on a 10 cm scale and MMT-8 ≤ 142 or CDASI total activity score ≥ 14
• Corticosteroid daily dose less than or equal to 20 mg prednisolone equivalent

Individuals may not be eligible to participate if they meet the following exclusion criteria:

• Cancer-associated myositis
• Evidence of active malignant disease or malignancies diagnosed in the previous 5 years
• Physician Global Damage score ≥ 3, or clinically relevant improvement between Screening Visit and Baseline
